CO2 gas develops constantly during fermentation. The regulated drainage was traditionally effected via bunging devices. This makes it possible to maintain the necessary pressure inside the tank for the fermentation process constant.
In an open system, the CO2 gas escapes into the environment; in the closed system versions, the CO2 gas is collected and recycled into the process at a later point of time. The development of the CO2 has is made visible during storage phase by a sight glass.
The bunging devices can be integrated into the CIP cleaning by a cleaning sleeve.
