What are the advantages and disadvantages of one-pot fermentation and two-pot fermentation? 【Small beer equipment]
A complete set of fine brewing beer equipment mainly consists of: crushing system, saccharification system, fermentation system, refrigeration system, control system, ice water tank, etc.
Fermenter is the main component. How much do you know about the methods, advantages and disadvantages of beer fermentation?
Today, small beer equipment manufacturers share with you.
One-pot fermentation is mainly conducted in the same tank for fermentation and post-ripening.
Advantages: the fermentation broth does not pour the tank, the operation is simple, and the fermentation broth has no chance to contact oxygen.
Disadvantages: the utilization coefficient of the fermentation tank can only reach 80%. compared with the two-tank method, the beer taste of the one-tank method is rough.
The two-tank fermentation is carried out in two tanks for fermentation and post-ripening. The fermentation tank completes the main fermentation, CO2 saturation and diacetyl reduction, and the post-ripening tank completes cold storage and maturation.
Advantages: the fermentation tank is filled with a coefficient of 80%, and the after-ripening tank can be filled with 90%;
The liquor is poured from the fermentation tank and then cooked. It can be cooled by a heat exchanger. The cooling effect is good, and it can be quickly put into cold storage. The cold coagulation is separated well, and the beer taste is refreshing and soft.
Disadvantages: the liquor needs to be poured once, which is complicated to operate and increases the loss of liquor. The back pressure of CO2 should be applied to the after-ripening tank, otherwise there will be more chances of contact with oxygen.
