Description

Technical Field

[0001] The utility model relates to the technical field of food processing and production, in particular to a sterilization device. Background Art

[0002] In the process of producing Guiling Gao, after filling, capping and sealing, the product needs to be sterilized in a sterilizer to increase food safety. The sterilizer is also called a sterilization kettle or a sterilizer.
