Steam from the vapor state into liquid, the volume will be reduced by more than 1200 times, if the sterilization pot in the steam full pot state, quickly into the top of the sterilization pot when the cooling water, due to the rapid condensation of steam may form a vacuum in the pot, which will damage the sterilization pot and pot cans.

Sterilization pot vacuum prevention:

1. In order to prevent this from happening, a suitable size negative pressure safety valve can be installed on the germicidal pot.

2. Prevent the cooling water from entering the top, and the cooling water must be cooled from the bottom of the sterilization pot.

3. Add a check valve to the waterway to prevent the phenomenon of water loss caused by rapid water replenishment.
