The element in wort like the malt sugar ,protein , enzyme and flavor molecule will take series action with beer yeast and hops ,become the beer with abundant alcohol and foam .

According to different brewing method ,the full fermentation period lasts for 8-20 days . Some special brewery plant prefer to keep craft beer for longer time in the oak barrel for deeper mature .

The beer after filtering can be put into bright beer tank for deeper fermentation .Normally the BBT specification is similar like fermentation tank ,also double layer with continuous cooling and insulation device . Sometimes the single layer BBT is also adopt ,putting into the cold room for continuous cooling .

The doubly layers of fermentation system tanks ,valves and pipes are made by stainless steel material . This keeps no rust element to destroy the beer flavor and hygienic condition ,also prolong the equipment using period .

There are different capacity BBT and fermentation tanks available , lasts from the micro brewery 50 liters to 10000 liters .

The detailed specification should adjust according to different brewing technology and customized actual needs . Fermentation tank capacity Vs mash tank capacity is always 1:1 or 2:1 . And the fermentation tank quantity is always 6 or 12 sets .

The wort fermentation period need continuous cooling temperature ,so the stainless steel cooling belts are welted on interior tank layer ,with cold glycol liquid recycle inside .And the PU insulation layer help a lot to save temperature .

The fermentation tanks fixed with plenty safty valves ,avoiding the pressure dangers during fermentation period .
