Resource reuse sterilization device in liquid fermentation process

The utility model discloses a resource reuse sterilization device in a liquid fermentation process. The device consists of a heating system, a feed liquid sterilization system, a cooling water system and a resource recovery system, feed liquid is distributed by the liquid distributor and uniformly distributed on the filler, a liquid film is formed on the filler, gaps are filled with the feed liquid, high-pressure steam from the steam bag is sprayed out through the air spraying holes, and the steam is in full contact with the liquid film on the filler, so that the heat exchange area is increased, the heat exchange effect is not influenced under the condition that non-condensable gas exists, and the heat exchange efficiency is improved. Compared with an existing sterilizer, the sterilization effect is better; the sterilized feed liquid enters the evaporation chamber after being throttled, redundant moisture of the feed liquid is evaporated in the evaporation chamber, and the drying effect is achieved while cool
