The aseptic filling machine maintains positive pressure operation using laminar flow sterile air at Class 100 cleanliness and employs dynamic liquid sealing technology to maintain a sterile environment. The equipment is manufactured using mirror welding technology to ensure smooth, flat welds without any unsanitary corners. Sterilization technologies include packaging material sterilization (such as hydrogen peroxide chemical sterilization and irradiation sterilization), container sterilization (such as chemical agents, ultraviolet light, and hot air), and product sterilization (such as UHT ultra-high temperature instantaneous sterilization, microwave sterilization, high-pressure sterilization, and radio wave sterilization). The Tetra Pak filling machine uses a hydrogen peroxide bath instead of a spray system; this highly efficient and continuous dry sterilization technology extends the aseptic production time from 72 hours to 144 hours.
The filling process uses a bottle-handling method with the bottle neck clamped, ensuring the filling nozzle does not contact the bottle container. Electromagnetic flowmeters or weighing methods are used for metering, and a mass weighing system controls quantitative filling. The product valves and moving parts of the filling head are protected by a vapor barrier. The automated control system utilizes a PLC (Programmable Logic Controller) and HMI (Human-Machine Interface) to achieve fully automated control and online monitoring. The proprietary flexible aseptic filling valve allows for one-button switching of filling modes across the entire production line.
The equipment features CIP (Cleaning in Place) and SIP (Sterilization in Place) systems, with integrated CIP cleaning and SIP sterilization processes. Inline production technologies such as the SIP-Bokma and SIG Cobbrass-Simon Nash combinations enable direct connection between bottle making and filling, reducing intermediate contamination and logistics costs. Cutting-edge technologies include electron beam (eBeam) sterilization technology.
