Beer processing relies on steam to provide heat source to complete processes such as gelatinization, saccharification, filtration, fermentation, canning, sterilization and disinfection. Pass the high-temperature steam generated by the steam generator into the pipelines of the gelatinization pot and the saccharification pot and heat them in sequence to fuse and gelatinize the rice and water, and then continue to heat to complete the saccharification process of the gelatinized rice and malt. In these two processes, the materials The required temperature depends on the heating time, so attention should be paid to adjusting the temperature of the brewing steam generator. It is understood that beer fermentation temperatures are divided into: low-temperature fermentation, medium-temperature fermentation and high-temperature fermentation. Low-temperature fermentation: vigorous fermentation temperature is about 8℃; medium-temperature fermentation: vigorous fermentation temperature is 10-12℃; high-temperature fermentation: vigorous fermentation temperature is 15-18℃. The general fermentation temperature in China is 9-12℃
After the saccharification is complete, it is pumped into the filter tank to separate the wort and wheat grains, continue to be heated and boiled and sent to the fermentation tank. The fermentation tank maintains a certain temperature all year round and produces carbon dioxide and alcohol under the action of yeast. After half a month of storage you get the finished product of beer.
The specific process of beer fermentation:
1. Soak barley malt in hot water to release maltose and form maltose juice.
2.After the wort juice is separated from the grains, it is boiled and hops are added for flavoring.
3. After the wort is cooled, add yeast for fermentation.
4. Yeast converts sugar juice into alcohol and carbon dioxide during fermentation.
5. After the fermentation is completed, it must be stored at controlled temperature for another half month to allow the beer to mature.
From the beer fermentation process, we can see that whether it is soaking in hot water, boiling or temperature-controlled storage, it is inseparable from heat, and the gas steam generator is a good heating method, with fast gas production and high thermal efficiency. , pure steam, multi-level temperature control and fully automatic operation, which can provide interlocking quality control for beer production.
In order to maintain a good taste of beer, when selecting steam equipment, it is recommended that the material be stainless steel. It has good antibacterial and antioxidant capabilities, making it easy to clean and sterilize; at the same time, the steam purity is extremely high, which is beneficial to maintaining the taste of beer. Therefore, in modern beer fermentation gas steam generators, in addition to whether the steam temperature can be adjusted at any time, the equipment must maintain a certain pressure. In addition, the selection of equipment materials cannot be careless.
Nobeth's special steam generator for brewing can be professionally customized according to your needs to create the equipment that best meets your production needs. The electronic control system can be operated with one button and the temperature and pressure are controllable. It is the best choice for brewing and fermentation.
