The pressure control for conical fermenterUtilizing conical tank for fermenting, it without pressure at the begining. In order to emission bad taste of volatile substances. When recycle CO2 adopt slight pressure(lower 0.01-0.02MPA). In the later period of fermenting that outsight fermenting level re

Indirect cooling method: the refrigerant is a mixture of ethanol or glycol and water, it is cooled in the evaporator box of the ammonia refrigerator, the temperature is generally controlled at around -5°C, the refrigerant flows in from below and out from above.Direct cooling method: The refrigerant
