(1)Gelatinizing tank,mash tank, filter tank and boiling tank all adopt closed round manhole. The manhole door must be closed in the production process to reduce the oxygen dissolution in the process of process operation as much as possible. (2)The inlet pipe of the mash and wort should be located at the bottom of the tank to reduce the contact between the mash and wort and oxygen during transportation.
