Vacuum Degassing Machine for Juice Processing

Introduction of Vacuum Deaerating Machines

The Vacuum Deaerating Machine is specially designed for juice, tea drinks, flavored water, energy beverages, and functional drinks that require dissolved oxygen removal before mixing and filling.

By using a high-vacuum environment, the machine efficiently removes oxygen, prevents oxidation, maintains product color, preserves original flavor, and improves beverage stability and shelf life.

This system is widely used in beverage factories, juice production lines, PET bottle filling lines, and aseptic hot-fill lines.

Why Deaeration is Essential

During beverage processing, dissolved oxygen can cause:

• Oxidation & color changes

• Off-flavor and aroma loss

• Lower CO₂ retention in carbonated beverage bases

• Shortened product shelf life

• Higher risk of bacteria growth

Our vacuum deaerator solves all of these problems.

Main Features of Vacuum Deaerating Machines

✔ High-Efficiency Oxygen Removal

• Vacuum chamber reduces dissolved oxygen to less than 0.5 mg/L

• Ensures stable beverage quality before mixing or filling

✔ Low-Temperature Vacuum Operation

• Oxygen removal under low temperature to avoid heat-induced flavor loss

✔ Stable & Continuous Degassing

• Inline design allows continuous oxygen removal

• Suitable for medium and large-scale production lines

✔ Improved Beverage Taste & Consistency

• Enhances clarity and flavor retention

• Improves CO₂ absorption for carbonated beverage preparation

✔ Hygienic & Food-Grade Construction

• SUS304 or SUS316 stainless steel

• All parts meet food safety standards

✔ CIP Cleaning Compatible

• Fully CIP-connected

• No need for manual cleaning

Working Principle of Vacuum Deaerating Machines

1. Beverage enters the vacuum tank through a special spray nozzle.

2. Under high vacuum, the surface area increases and dissolved oxygen escapes quickly.

3. Deaerated beverage flows to the storage tank, ready for mixing, homogenizing, or filling.

4. Vacuum is maintained automatically by a high-performance vacuum pump.

This process ensures stable and consistent deaeration with minimal energy consumption.

Applications of Vacuum Deaerating Machines

Ideal for removing dissolved oxygen from:

• Fruit juice (apple, orange, mango, pineapple, etc.)

• Tea beverages (black tea, green tea, herbal tea drinks)

• Functional drinks

• Flavored water

• Syrups and concentrated beverage bases

• Dairy beverages (optional configuration)
