Water bath double-layer sterilization potThe high temperature of the process water shortens the heating time and improves work efficiency，energy conservation. The process water used in the sterilization process can be recycled, saving energy, time, and manpower, and reducing production costs，Temperature control is stable. Adopting a newly designed liquid flow switching device, the process water continuously switches between upward, downward, left, and right circulation, eliminating blind spots during the sterilization process
