When you clean your beer brewery equipment, you may prefer to clean the fermentation tanks with hot water or sterilizing the fermenter tanks with steam, actually it is very dangerous.
Under ordinary pressure, the weight of 1M3 steam at about 560g, but the weight of 1M3 water is 1ton. Means if the steam is condensed, its volume will reduce to 1/1786 of origin. That may cause negative pressure and make the tank dangerous.
Besides, when the discharging speed is much faster than the air flowing in speed; Or when the fermentation tanks washed by hot caustic liquid, the CO2 absorbed by the caustic liquid and caused volume shrinkage; Or the tanks washed by cold water after it is just showered by hot liquid etc. All these operations will cause negative pressure in the fermentation tanks.
So the temperature for cleaning beer fermenters better not exceed 40℃.
If you have any other questions on brewery equipment cleaning, please feel free to talk with us!
