Bottle Inverted Sterilizer

FAQ: Bottle Inverted Sterilizer

1. What is a bottle inverted sterilizer?

A bottle inverted sterilizer is an inline thermal sterilization machine used to sterilize the bottle neck, inner cap area and upper bottle wall after hot filling. The filled bottle is automatically inverted so that the hot beverage contacts the cap and neck area.

2. How does the bottle inverted sterilizer work?

After hot filling and capping, bottles enter the machine and are gradually inverted by 90°–180°. They remain inverted for a preset holding time, usually 30–60 seconds, before returning to the upright position and moving to the cooling tunnel.

3. What beverages can be processed with this machine?

The bottle inverted sterilizer is mainly used for hot-fill beverages, including fruit juice, nectar, tea, functional drinks, vitamin beverages, herbal drinks and some low-viscosity dairy beverages.

4. What bottle sizes and capacities are supported?

The machine is suitable for PET bottles from approximately 150 ml to 2 L. Depending on the bottle type and production requirements, capacity can range from 2,000 to 36,000 bottles per hour.

5. Does the machine require steam or chemical sterilization?

No. The bottle inverted sterilizer uses the heat of the hot-filled beverage for thermal sterilization. It does not require additional steam or chemical disinfectants, which helps reduce energy consumption and simplify operation.

6. Can the sterilizer be connected to an existing production line?

Yes. It can be installed between the hot filling and cooling sections of an existing beverage line. The inversion angle, holding time, bottle format and conveyor layout can be customized according to the customer’s production requirements.

7. What information is needed for a quotation?

Please provide the beverage type, bottle material and size, filling temperature, required holding time and production capacity. Nancheng Machinery can then recommend a suitable bottle inverted sterilizer configuration.
