 Use reverse pressure cooking.In simple terms, compressed air is used to pass into the pot to increase pressure to prevent cans from being raised and jump caps. The operating procedure is analyzed as follows: the compressed air is a poor heat conductor, and the steam itself has a certain pressure.So in the sterilization heating process, do not put compressed air, but only to reach the sterilization temperature in the heat preservation state.After sterilization, when cooling, stop the supply of steam, cooling water into the spray pipe.As the temperature in the pot drops, the steam condenses, and the pressure in the pot decreases using compressed air to compensat
