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 figure shows a glass bottle aseptic packaging device of Dole Inc., which is composed of an empty bottle sterilizer, a sterile ring-type 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. Since the surface of the glass bottle is only exposed to 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 connected.
262' (; Superheated steam remains sterile, the direct-injection girth filler will inject the aseptic product into the bottle at a constant flow rate. The aseptic capper is similar to a normal automatic steam jet vacuum bottle sealer, but with overheating. The steam is kept sterile, and it can be used for the capping of the swivel cap and the swivel cap, and the caps are automatically oriented and arranged in the cap feeder to be sent to the cap sterilizer, which is automatically placed on the bottle cap that has been filled into the capping machine after being sterilized with superheated steam. , Then automatic capping, packaging products sent out of the machine.
