Based on the advanced technology of similar foreign products, our company has independently developed a PET aseptic cold filling production line. The aseptic cold filling production line adopts aseptic isolation technology to ensure the sterilization of filling materials, packaging environment and packaging containers. Sterilize the bottle and cap by soaking in disinfectant to ensure the sterility of the packaging container. The internal and external surfaces of the equipment are cleaned and sterilized by the SOP method, and the filling environment is kept at positive pressure by using sterile air to achieve a 100-level clean environment. The material pipeline is cleaned and sterilized by CIP and SIP, which ensures that the material after UHT sterilization is not contaminated, and ensures that the final product meets the commercial sterility requirements. The PROFINET bus control technology is used to realize the communication between single machines and the control of the whole line, online display of the running status of the whole line and fault alarm, which greatly improves the level of automatic control and reduces the possibility of human misoperation.



- Adopting modular design, the empty bottle sterilizer, empty bottle washing machine, filling machine and capping machine are combined into a five-in-one unit, and the part above the table is sealed with an isolation cover.
- Empty bottle sterilizer uses empty bottles to be sprayed and sterilized by two sterilizers on the same platform in turn.
- The rinser is designed with sterile water for internal flushing, external washing and draining.
- The filling valve adopts non-contact type, which can effectively prevent secondary pollution.
- Electromagnetic flowmeter is used to measure the filling volume, with high measurement accuracy and easy adjustment of product varieties.
- Equipped with an automatic fake bottle mechanism, which automatically fills fake bottles during CIP cleaning and SIP sterilization.
- Using the Italian AROL upper turret system to ensure the qualification rate and stability of the screw cap.
- Set up centralized automatic lubrication system.
- The interior of pipes and valves in contact with materials are all sanitary standards.

The caps are sent to the capping machine after passing through the cap conveyor, capping machine, sterilizing machine, rinsing with sterile water, and drying with sterile air.
Sterile water system, sterile air filtration device, disinfectant preparation system, steam filtration device and CIP/SIP system are all necessary peripheral equipment for aseptic filling.
The key to aseptic filling of PET bottles is how to realize the aseptic treatment of filling materials, production environment (filling equipment, filling environment), packaging materials (empty bottles, bottle caps), etc. in the filling process to ensure that the final product is commercially sterile.
