One-Tank Fermentation Method Vs Two-Tank Fermentation Method

Single tank fermentation” means that the entire fermentation process is done in the same tank, at which point we refer to the fermenter as a single tank.

The advantages of “single tank fermentation” are simple operation, easy to control temperature, pressure or level, easy to collect or recover yeast, and no need to transfer the beer to another tank, which can reduce the oxidation of beer and reduce the loss of beer. The disadvantage is that the beer is more convective and many residues do not drain well, so the beer does not taste very smooth. In addition, the fermenter is poorly utilized.

Double tank fermentation” means that the primary fermentation takes place in the fermenter and the secondary fermentation takes place in the salting tank.

It has the advantage that the utilization rate is much higher; after the yeast from the primary fermentation is drained, the yeast can settle completely, so the beer looks clearer. The disadvantage is that the beer is easily oxidized during the transfer from the fermentation tank to the bright tank. Therefore, please be more careful during the operation.
