When the bags are produced, each batch should be sampled for inspection. The performance should meet the requirements in the figure below before the high temperature sterilization process can be used. Although each batch of products are qualified in the factory inspection, if the application process is not reasonable, it will also cause bag breakage, which will affect the reputation of the manufacturer. Therefore, the manufacturer should also master the sterilization process to find out the cause of bag breakage.
At present, the domestic high-temperature sterilization process mostly adopts 121 ℃, 30-45min, the equipment is simple, and the operators are mostly small-scale production mode. The equipment schematic diagram is as follows: first, inject high-pressure steam to make the high temperature in the boiler rise to 121 ℃ and keep the constant temperature for 30-45min. If the pressure rises or falls, steam injection or discharge is used to adjust the process, but the pressure must be stable and must not fluctuate. After that, cool air is injected and steam is released at the same time, and the pressure is still stable. After 5min, it stops. Finally, it is cooled by cold water to complete the sterilization process. During this period, the bag will be broken seriously if the pressure fluctuates greatly. Among them, the ts-25c high-temperature cooking pot produced by Beijing landmec Co., Ltd. can achieve the purpose of not breaking the bag by airtight back pressure and cooling water.
