Glass Bottle Berry Juice Production Line in Europe: Installation And Commissioning Case Study

A beverage production line is not a collection of machines placed in sequence. It is an integrated process system in which product preparation, thermal treatment, filling, bottle handling, utilities, controls and downstream equipment must operate under coordinated conditions.

This distinction becomes especially important during site installation.

A filling machine may perform correctly during factory testing, but final production performance is determined only after the equipment is installed in the customer's plant and connected to the actual process piping, electrical system, conveyors and utilities. At this stage, machine alignment, product-transfer stability, glass bottle handling, line interlocks and upstream-downstream capacity matching become as important as the performance of the individual filler.

Nancheng Machinery's latest 2000BPH glass bottle berry juice production line in Europe is currently entering this system-integration phase.

The project includes berry juice processing equipment, sterilization, glass bottle rinsing, filling and capping, continuous spray treatment and conveying systems. The main product-contact sections are manufactured from SUS304 stainless steel.

Following international transportation, the main production equipment, stainless-steel tanks, filling system, spray-treatment equipment, conveyors, water-treatment equipment and supporting units have arrived at the customer's facility and have been progressively positioned inside the production area.

The next project stage will focus on process piping, electrical connection, individual-machine commissioning and complete-line coordinated testing.

For this type of glass bottle juice production line, the key engineering task is not simply to complete mechanical installation. It is to verify that every section of the process can operate together at the required production conditions.

That includes stable beverage preparation, controlled product transfer, reliable glass bottle conveying, compatible thermal treatment, sufficient utility capacity, correct machine-to-machine communication and balanced line throughput.

This European berry juice project therefore provides a practical case for examining how a beverage line moves from equipment delivery to integrated production engineering.

European Berry Juice Project: From Equipment Delivery to Site Integration

International delivery marks an important project milestone, but it does not establish production capability.

Before shipment, individual machines can be inspected under controlled factory conditions. Once the equipment reaches the customer's plant, a new set of engineering variables appears: actual floor conditions, equipment elevations, pipe routes, electrical distribution, utility capacity, maintenance clearance, bottle supply and upstream-downstream machine interaction.

The European berry juice project has already completed the manufacturing, packaging, international transportation and unloading stages. Major machines have been transferred into the customer's production workshop, while the factory infrastructure has been prepared in parallel for installation. The main machines, curved bottle conveyors and continuous spray-treatment equipment have been initially positioned to support the next mechanical, piping and electrical stages.

This transition from delivery to site integration is critical because problems that are invisible during isolated machine testing often become apparent when the machines are connected.

The process system must supply the filler continuously. The filler must handle the actual glass bottle correctly. The capping section must operate at compatible speed. The downstream thermal-treatment section must accept upstream output without creating excessive accumulation. Utilities must remain stable when the complete line operates simultaneously.

These interfaces ultimately determine production stability.

Engineering Design Basis: Define the Juice, Bottle and Process First

The design of a berry juice production line should begin with the beverage and package rather than with a filling-machine model.

Two projects can have the same nominal BPH requirement while requiring substantially different process equipment.

A low-viscosity filtered beverage and a berry product containing suspended fruit material may need different pumps, piping, tank arrangements, product passages and cleaning strategies. The target output alone does not describe these requirements.

A practical design basis should establish the following parameters before equipment configuration is frozen.

The current European project information does not specify Brix, pH, viscosity, pulp concentration or particle size. Those values should therefore remain part of the project-specific process documentation rather than being assumed in a public case study.

This distinction is important in technical content. Engineering decisions should be based on confirmed process data rather than generic values copied from another juice project.

For formulations requiring controlled mixing, homogenization, storage or thermal processing before filling, the upstream process section must be engineered together with the packaging system. Nancheng's Juice Beverage Preparation System provides a broader reference for this upstream process architecture.

Why Berry Juice Cannot Be Engineered Like Bottled Water

Water and berry beverages may pass through similar-looking filling equipment, but their product behavior can be very different.

Water is generally low in viscosity and contains no fruit solids. Berry-based beverages may contain dissolved sugars, natural pigments, suspended material or pulp, depending on the formulation.

These characteristics influence pumping, product circulation, heat transfer, pipeline design and cleaning.

A narrow product passage that performs well with water may not be suitable for a juice containing suspended particles. A process circuit that can be rinsed quickly after water production may require more controlled cleaning after handling a colored, sugar-containing beverage.

This is why a fruit juice processing line should not be created by simply adding a juice filler to a water-production layout.

The product characteristics influence the entire process architecture.

Map the Complete Glass Bottle Juice Production Line as One System

A strong production-line design follows the complete product and container flow rather than treating individual machines as independent purchases.

For this type of project, the engineering sequence can be divided into several connected functional sections.

The engineering value lies in the relationships between these sections.

The filler cannot operate continuously when upstream product preparation supplies beverage intermittently. A downstream spray-treatment tunnel can become the effective production bottleneck if its sustainable throughput is lower than the filler output. Bottle conveyors must provide sufficient decoupling between machines without creating excessive glass-to-glass pressure.

The complete process should therefore be designed around the required finished production rather than around one machine's maximum rating.

For a broader view of how beverage preparation, filling, thermal treatment and downstream packaging are combined, see Nancheng's 2000BPH Juice Production Line solution.

Site Layout and Equipment Positioning Before Final Installation

Equipment positioning is not simply a logistics activity.

It establishes the physical references for conveyor alignment, sanitary piping, utilities, cable routes and maintenance access.

Before permanent fixing, the actual production floor should be compared with the approved layout.

Machine Centerline and Transfer Alignment

The centerlines of connected machines influence bottle stability at every transfer point.

A small alignment error may not create an obvious problem during slow manual movement. At production speed, however, the same error can cause repeated bottle contact, unstable transfers or jams.

This is particularly important around the filler infeed, filler discharge, conveyor transitions and the entrance and discharge of post-fill treatment equipment.

Equipment Elevation

Machine elevation has similar importance.

Conveyor surfaces and transfer plates must align correctly for glass bottle handling. Process equipment elevation can also influence pipe routing, drainage and pump conditions.

Equipment should therefore be leveled and verified before final piping is completed.

Machine Footprint Is Not the Required Installation Area

A machine drawing normally shows the physical footprint of the equipment.

It does not represent the complete operating and maintenance envelope.

A practical layout also requires space to open electrical cabinets, remove motors and pumps, access filling valves, inspect capping components, service conveyors and clean around the equipment.

This principle is also central to Nancheng's existing beverage layout methodology: a compact layout remains useful only when the equipment is serviceable.

Saving a small amount of floor area during installation can create significant maintenance difficulties over the lifetime of the plant.

Glass Bottle Handling: Transfer Stability, Breakage and Controlled Accumulation

Glass bottles require different conveying priorities from lightweight PET containers.

They are rigid, comparatively heavy and susceptible to mechanical impact.

For this reason, conveyor engineering forms part of filling-line performance rather than functioning only as transportation between machines.

Guide Rails and Bottle Transfer Points

Guide rails should stabilize the selected bottle without generating unnecessary side pressure.

Actual settings depend on bottle diameter, profile, height and center of gravity.

Every transfer between two conveyors or between a conveyor and a machine represents a potential disturbance. Reducing unnecessary transitions and maintaining correct alignment improves bottle stability.

Accumulation Pressure and Breakage Risk

Accumulation conveyors are valuable because they prevent every short machine interruption from immediately stopping the complete line.

However, excessive accumulation is not automatically beneficial for glass.

Uncontrolled bottle-to-bottle pressure can increase impact and breakage risk. The system therefore needs sufficient buffering without allowing excessive contact pressure to develop.

There Is No Universal Conveyor Buffer Length

Buffer requirements cannot be determined from BPH alone.

The appropriate accumulation capacity depends on the bottle, production speed, machine-stop frequency, typical interruption duration, restart behavior and available factory space.

The objective is controlled decoupling between machines.

The objective is not to install the longest possible conveyor.

Process Piping Design for a Berry Juice Production Line

Once the major equipment positions are verified, the process-piping system connects the upstream preparation equipment with the filling section.

Pipework directly influences flow stability, pressure loss, product recovery, sanitation and cleaning.

Pipe Diameter Must Match Actual Process Flow

There is no universal pipe diameter for juice processing.

An undersized pipe can generate unnecessary pressure loss and increase pump demand. An unnecessarily large pipe can increase product hold-up, cleaning volume and product losses during changeover.

The correct diameter depends on required flow, product properties, pump characteristics and process conditions.

Product Hold-Up Should Be Controlled

Long and unnecessarily complex product routes retain more beverage inside the process circuit.

That can increase product loss during production changeovers and increase the volume of water and cleaning chemicals required during sanitation.

Where practical, beverage preparation and filling should therefore remain reasonably close.

This does not mean selecting the shortest pipe route at all costs.

The route must also remain drainable and maintainable.

Drainability Is Part of Hygienic Design

Pipe routing should minimize unintended low points and areas in which juice or cleaning liquid can remain after production.

This becomes more important with beverages that can leave sugar, pigment and organic residues.

Poor drainage can increase cleaning time and make sanitation less repeatable.

Valves and Instruments Must Remain Accessible

A technically correct pipe route can still be poorly engineered if important valves, sensors or pumps cannot be accessed for maintenance.

Process performance, cleanability and serviceability should therefore be evaluated together.

Hygienic Design: SUS304 Is the Starting Point, Not the Complete Answer

The European project's main product-contact sections use SUS304 stainless steel.

Material selection is important, but stainless-steel grade alone does not define hygienic performance.

Cleanability also depends on internal surface quality, welding, pipe geometry, valve design, gasket installation, drainage, product dead zones and the arrangement of the cleaning circuit.

A stainless-steel pipeline can still retain product if the geometry prevents effective drainage.

Designing the Product Circuit for Cleaning

Cleaning requirements should be considered while the process circuit is being designed.

For a CIP-capable system, the engineering team should identify which tanks, pipelines, valves and filling-product circuits are included in the cleaning route.

Flow must reach the required surfaces and the circuit must be capable of draining after cleaning.

This is more meaningful than simply stating that a production line is "equipped with CIP."

The important engineering issue is whether the required product-contact circuits can be cleaned repeatedly and returned to the defined hygienic condition.

Berry Juice Residues Increase the Importance of Cleanability

Berry beverages can leave more visible and persistent residues than plain water.

Sugars, pigments and organic material may remain on tanks, pipes and valves if cleaning coverage is poor.

For that reason, good sanitary design reduces not only hygiene risk but also changeover time, water consumption, chemical consumption and production loss.

Thermal Integration Between Berry Juice and Glass Bottles

Thermal processing should be evaluated as a system rather than as one temperature set point.

The relevant process may include heating, holding, product transfer, filling, closure, post-fill treatment and cooling.

Each stage affects the condition entering the next stage.

Processing Temperature and Filling Condition Are Different Variables

The product leaving a thermal-treatment system does not necessarily reach the filler under exactly the same conditions.

Pipe length, transfer time, intermediate storage and production interruptions can influence the product condition at the filling machine.

The thermal process therefore needs to be considered across the complete product path.

Glass Bottles Introduce Thermal-Stress Considerations

Glass has good rigidity but can be sensitive to rapid temperature changes.

The acceptable thermal profile depends on the bottle design, wall distribution, glass quality and bottle manufacturer's specification.

For this reason, a fixed universal maximum temperature difference should not be applied to every glass bottle project.

The heating and cooling profile must match the actual bottle and validated product process.

Post-Fill Spray Treatment: Thermal Control and Line Capacity

The European project includes a continuous spray-treatment section.

From an engineering perspective, this machine is not simply a conveyor fitted with spray nozzles.

Its performance depends on the interaction between temperature zones, spray conditions, residence time, conveyor speed and bottle characteristics.

Conveyor Speed Influences Thermal Performance

Changing conveyor speed changes the residence time inside each section of the tunnel.

A mechanical speed adjustment can therefore alter the thermal process.

Line speed and thermal treatment cannot always be adjusted independently.

The Spray Tunnel Can Become the Actual Bottleneck

A filler rated above the sustainable capacity of the downstream treatment section does not create a production line with the filler rating.

If the tunnel limits continuous output, the tunnel defines the stable line speed.

This illustrates one of the most important principles in complete-line engineering:

the real bottleneck is determined by system interaction, not by the largest or most expensive machine.

Utilities Required Before Juice Line Commissioning

Many production problems that appear to be machine faults originate in the utility system.

A machine can operate correctly during isolated testing but become unstable when multiple machines operate simultaneously.

For the European project, factory infrastructure preparation has been progressing together with machine positioning.

Utilities should be confirmed before complete-line commissioning.

Electrical Demand Must Be Evaluated at Line Level

Installed electrical load and normal simultaneous operating demand are not identical values.

The electrical distribution system should be engineered around the actual operating sequence of the plant.

Compressed Air Supply Must Remain Stable

Pneumatic valves, cylinders and actuators depend on stable compressed-air conditions.

Pressure drop through the factory distribution network should be considered in addition to compressor rating.

Heating and Cooling Capacity Must Match the Process

Thermal processing and post-fill treatment can create substantial heating and cooling demand.

These requirements should be calculated from the process equipment and simultaneous operation rather than estimated only from filler BPH.

Drainage Is a Production Utility

Cleaning, equipment washing and thermal systems can discharge significant volumes of water.

Insufficient drainage can interrupt sanitation and production even when the machinery itself is operating correctly.

Define Utility Battery Limits Before Site Installation

International beverage projects require clear responsibility boundaries.

The equipment supplier may provide the machine-side utility connection. The customer may provide the main plant supply. A local contractor may be responsible for the pipe, cable or service connection between them.

These boundaries are commonly described as battery limits.

They should be defined before site installation rather than during commissioning.

Clear battery limits reduce ambiguity over electrical distribution, process piping, compressed-air lines, water connections, drainage and heating or cooling utilities.

This is particularly important when the machinery supplier, customer engineering team and local installation contractor are working in parallel.

Electrical Integration: From Machine Automation to Line Automation

Individual machine automation and complete-line automation are not the same concept.

A filler may operate perfectly in manual or stand-alone automatic mode. Stable production requires it to respond correctly to upstream and downstream conditions.

Upstream and Downstream Communication

If downstream equipment stops, upstream bottle flow needs to respond before uncontrolled accumulation develops.

If the product supply system cannot maintain the required condition, the filling section may also need to react according to the control philosophy.

Depending on the project architecture, machines can exchange run, ready, fault, demand and backup signals.

Interlocks Protect the Complete Process

Typical control functions can include bottle-backup detection, product-level protection, pump interlocks, conveyor interlocks, guard monitoring and emergency-stop communication.

The specific PLC sequence depends on the supplied equipment.

The engineering principle remains the same: a local machine fault should be managed in a way that prevents unnecessary secondary problems elsewhere in the line.

Line Balancing: Rated BPH vs. Saleable Production Output

BPH is useful for equipment selection, but it should not be treated as equivalent to factory output.

A filler rated at a particular speed does not automatically produce the same number of finished bottles every hour.

This distinction is also emphasized in Nancheng's Complete Beverage Filling Line Layout Guide, which separates individual machine rating from stable line speed, net production and final packaged output.

A line can lose output because of product preparation, bottle supply, capping, thermal processing, labeling, packing, cleaning, changeovers or repeated short stops.

Identifying the Real Bottleneck

The bottleneck is the process section that restricts sustainable production under real operating conditions.

It may be the filler, but it may also be the upstream processing system, bottle-handling system, spray tunnel or downstream packaging equipment.

For this reason, commissioning should verify complete-line behavior rather than demonstrating only that the filler can briefly reach its nominal BPH.

The engineering target is stable finished output.

Installation and Commissioning Sequence for the European Juice Line

The next confirmed stages of the European project are process-pipe connection, electrical wiring, individual-machine commissioning and complete-line coordinated testing.

A staged commissioning sequence makes fault isolation easier and reduces the number of variables introduced at one time.

Equipment Positioning and Mechanical Alignment

Machine position, level, conveyor interfaces and mechanical clearances should be verified before permanent connections are finalized.

Layout corrections are considerably easier before stainless piping and fixed utility services are completed.

Process Piping and Utility Connections

Product lines and utilities are then connected according to the approved site design.

Flow direction, pipe routing, accessibility and drainage should be checked during installation rather than after product commissioning.

Electrical and I/O Verification

Motors, sensors, actuators, safety circuits and machine-to-machine signals should be verified individually.

Correct physical wiring does not automatically guarantee correct PLC response, so both input and output functions need checking.

Dry Running

Where appropriate, bottle movement and mechanical sequences can first be tested without beverage.

Dry testing is useful for identifying conveyor-direction errors, guide adjustments, unstable transfers and control-sequence problems.

Water Testing

Selected process and filling circuits can then be tested with water or another agreed medium.

This allows technicians to check pumps, valves, leakage, flow and control functions with lower product-loss risk.

Product Commissioning and Speed Ramp-Up

Actual product introduces the real beverage characteristics into the line.

Operating speed should normally be increased progressively while filling behavior, capping, bottle movement, thermal treatment, accumulation and interlocks are observed.

The target should not be one short maximum-speed demonstration.

It should be stable and repeatable production.

FAT vs. SAT: Two Different Engineering Verification Stages

Factory Acceptance Testing and Site Acceptance Testing have different objectives.

Factory Acceptance Test: Verify Equipment Before Shipment

FAT is carried out under agreed factory test conditions before shipment.

Depending on the project scope, it can verify mechanical operation, controls, alarms, bottle handling, safety functions and agreed equipment-performance criteria.

Its primary purpose is to identify equipment-related issues before international transportation.

Site Acceptance Test: Verify the Installed System

SAT takes place after installation at the customer's production facility.

It introduces the actual site conditions: customer utilities, final piping, electrical infrastructure, equipment positions, project containers and machine interfaces.

SAT therefore evaluates the installed production system rather than simply repeating factory testing.

Acceptance Criteria Should Be Defined Before Testing

A meaningful acceptance test should define the test conditions in advance.

Relevant items can include test medium or product, bottle and closure specification, production speed, test duration, package-quality criteria and allowable interruption conditions.

Without predefined criteria, statements such as “the line runs well” remain subjective.

Five Engineering Risks That Can Delay a Glass Bottle Juice Line Start-Up

Layout Frozen Before Site Verification

Actual building dimensions, floor conditions, doors, columns and drainage positions can differ from early layout assumptions. Permanent fixing before site verification can create unnecessary mechanical and piping rework.

Utilities Sized Below Simultaneous Demand

Utilities that support one machine during isolated testing may become insufficient when the complete line operates.

Poorly Drained Product Piping

Unintended liquid retention increases sanitation difficulty, cleaning time and product losses.

Insufficient Glass Bottle Buffer Control

Too little accumulation causes unnecessary complete-line stops, while excessive uncontrolled accumulation can increase bottle contact and breakage risk.

Downstream Equipment Becomes the Capacity Bottleneck

Additional filler capacity provides little practical benefit if the downstream thermal-treatment or packaging system cannot sustain equivalent output.

Pre-Start Engineering Checklist for a Glass Bottle Juice Production Line

A pre-start checklist is valuable because it forces the project team to evaluate the production system as a whole.

Successful motor rotation alone does not demonstrate plant readiness.

Engineering Lessons From the European Glass Bottle Berry Juice Project

Equipment Delivery Is Only a Project Milestone

The European project confirms the importance of separating logistics completion from engineering completion.

Major equipment has arrived safely and is being positioned, but the project still requires process, utility, control and commissioning integration before regular production.

System Interfaces Determine Production Stability

Most complete-line problems develop at interfaces.

The important boundaries include process system to filler, filler to conveyor, conveyor to thermal treatment, machinery to factory utilities and individual PLCs to the complete control architecture.

Rated Capacity Must Be Verified at Line Level

An individual machine reaching rated speed does not demonstrate equivalent finished production.

Actual capacity must be proven with the connected process operating together.

Commissioning Converts Installed Machinery Into a Production System

This is the central engineering purpose of commissioning.

Mechanical, electrical and process systems are progressively tested until the line can operate as one coordinated manufacturing system.

Why Choose Nancheng Machinery for a Glass Bottle Juice Production Line?

Selecting a supplier for a glass bottle juice production line involves more than comparing filling-machine specifications.

The project requires coordination between beverage processing, packaging, utilities, layout and site commissioning.

Engineering Starts With the Product and Package

Nancheng's project approach begins with the beverage, bottle, closure, production requirement and available factory conditions.

This provides a stronger design basis than selecting a standard filling-machine model first and attempting to adapt the remaining equipment afterward.

Upstream Processing and Filling Are Considered Together

Stable filling depends on stable product preparation.

Mixing, storage, thermal treatment, pumping and product transfer therefore need to be matched to the filling section.

The engineering objective is continuous process compatibility rather than independent machine selection.

Complete-Line Integration Extends Beyond the Filler

The project scope can include layout planning, product-processing interfaces, filling and capping, conveyors, post-fill treatment, utilities, control communication and commissioning.

Nancheng's Turnkey Beverage Line Solutions describes this broader system-level approach to beverage project planning and integration.

Site Installation Is Treated as an Engineering Stage

The current European project illustrates this clearly.

Equipment delivery has been followed by site positioning, while subsequent work includes piping, electrical connection, individual equipment commissioning and complete-line coordination.

Installation is therefore treated as part of the engineering process rather than as a simple mechanical assembly task.

The Final Target Is Stable Line Performance

A short run at maximum filler speed is not the final measure of project success.

The more meaningful objective is stable, repeatable production in which product preparation, glass bottle handling, filling, capping, post-fill treatment, utilities and controls remain coordinated.

That system-level performance is what converts installed machinery into commercially useful production capacity.

Frequently Asked Questions About Glass Bottle Juice Production Lines

What Equipment Is Included in a Glass Bottle Juice Production Line?

A complete project may include water treatment, juice preparation, thermal processing, storage tanks, pumps, sanitary pipelines, glass bottle preparation, rinsing, filling, capping, post-fill thermal treatment, conveying, labeling and secondary packaging.

The final configuration depends on the beverage, package, closure, production process and required finished output.

How Is a Berry Juice Filling Line Different From a Water Filling Line?

Berry beverages can differ from water in viscosity, dissolved solids, suspended material, thermal-processing requirements and sanitation demand.

These differences can affect tanks, pumps, pipework, filling passages and cleaning-system design.

What Utilities Are Required for a Juice Production Line?

Typical requirements can include electrical power, process water, cleaning water, compressed air, heating media, cooling water and drainage.

The required capacities should be calculated from the confirmed complete-line configuration and simultaneous operation.

How Much Conveyor Buffer Does a Glass Bottle Filling Line Need?

There is no universal buffer length.

The required accumulation depends on line speed, bottle geometry, machine-stop behavior, restart time and the degree of decoupling required between connected equipment.

Glass bottle contact pressure must also be considered.

What Is the Difference Between FAT and SAT for a Beverage Filling Line?

FAT verifies equipment before shipment under agreed factory conditions.

SAT verifies the installed system after site integration, including customer utilities, final pipework, machine interfaces and actual project conditions.

When Is a Juice Production Line Ready for Commercial Production?

Mechanical installation alone is not sufficient.

Relevant piping, utilities, electrical systems, safety circuits, individual-machine functions, product handling and complete-line performance should be commissioned and verified according to the agreed acceptance plan.

From Delivered Equipment to Stable Commercial Production

A glass bottle juice production line shall be evaluated as a holistic integrated production system rather than a mere assembly of discrete individual machines.

While machine technical specifications, stainless steel material grades and rated bottles per hour (BPH) capacity serve as critical reference benchmarks, they cannot independently determine the final production performance and operational outcomes. Consistent and stable production output hinges on the seamless synergy and efficient coordination of upstream processing procedures, product transfer systems, filling and capping units, glass bottle conveying systems, post-filling treatment processes, as well as utility systems and electrical control systems across the entire line.

The product preparation system must deliver continuous, consistent feed to the filling machine while complying with specified process parameters and sanitary requirements. Sanitary process piping shall be designed to deliver optimal flow characteristics, with full drainability and cleanability to meet food-grade production standards. Bottle transfer via conveyors and machine interconnections must maintain operational stability, eliminating excessive mechanical impact and stacking pressure. Thermal treatment processes need to be precisely aligned with both beverage formulation processing requirements and the structural characteristics of specified glass packaging containers. In parallel, supporting utilities including electric power, compressed air, process water, heating and cooling systems must sustain stable operation during full-line synchronous production.

The European berry juice project is currently advancing into the core system integration phase. All major process equipment has been delivered to the client’s production site and completed preliminary positioning and layout. The subsequent construction phase will cover sanitary process piping installation, electrical system integration, single-machine commissioning and full production line integrated testing.

For manufacturers undertaking similar glass bottled juice production line projects, the engineering implementation workflow shall adopt a standardized system-level methodology: define beverage product attributes and packaging specifications, confirm targeted finished production capacity, formulate the full-process technical scheme, verify equipment interface compatibility, complete on-site system integration, and validate operational performance under actual production conditions.

In this context, equipment delivery merely marks the completion of the equipment supply stage.

A project is deemed fully completed only when the integrated production line achieves stable, repeatable and commercially viable mass production.
