Application of Glass Bottle High Temperature Sterilization Technology

Glass bottle packaging technology is increasingly oriented towards high strength and light weight, and the thermal shock resistance of glass bottles is also greatly improved. Even if the temperature difference between inside and outside is 800 degrees (above the above, it will not produce cracks, which greatly promotes its asepsis. The application of packaging technology.The British Dairy Research Institute first developed a glass bottle aseptic packaging technology, using 154′(;, 4. 8MPa superheated steam blown to the glass furnace heating 1. 5s -2s, sterilization after filling sterilized milk, The seal forms an aseptic packaging product.

The Dole Inc. glass bottle aseptic packaging device is composed of an empty bottle sterilizer, a sterile ring-built filling device, a bottle cap sterilizer and a capping type aseptic filling bottle machine. The entire system uses overheating to save the sterility of the bottles and caps and maintain the sterility of filling and capping. The empty bottles are sent to the trap inside the sterilizer, which is first pumped into a high vacuum to purify the gas and the air inside the bottle. It is sterilized by 154-c, 0.4MPa wet steam for 1.5s-2s. Because the glass bottle surface only receives instantaneous high heat, the glass bottle is quickly cooled to 49' (before and after it enters the filler). The filler is sterilized in advance and passes through 262' (; the superheated steam remains sterile, the direct injection ring The septum filler injects the aseptic product with a constant flow rate into the bottle.

The aseptic capper is similar to an ordinary automatic steam jet vacuum sealer. However, the use of superheated steam to maintain sterility can be used for swing caps and pressure cap closures. Bottle caps are automatically and directionally arranged from the cap feeders and sent to cap sterilizers. They are automatically placed on the bottle caps that have been filled into the capping machine after being sterilized with superheated steam. The caps are then automatically capped and the finished packaged products are sent out of the machine.
