Bright beer tanks – BBT

Tanks for secondary fermentation and maturation of the beer, also known as BBT, are these where the beer is transferred after its initial fermentation process and separated from the hop yeasts in the CCT. BBT’s design consist torispherical top, cylindrical body and torispherical bottom. These are tanks working under pressure, insulated and equipped like CCT with cooling jacket, safety fittings, washing device and a manhole for inside access and also have hygienic design. BBT’s are special tanks intended only for the second phase of the beer fermentation process. During this phase the beer slowly ferments secondary at low temperature under pressure as it naturally saturates with carbon dioxide which is formed from remaining activity of the hop yeasts. This phase is also called maturation of the beer. It is the longest stage of the beer manufacturing process where taste characteristics are formed. The continuance of the beer maturation process depends on the chosen recipe, temperature and set pressure in the tank.

Depending on the capacity of the brewery, these tanks can be manufacturing in various volumes and sizes, to be suitable for installation in any premises. This type of tanks can be installed outside buildings when needed or when capacity requires larger size, but with construction allowing the proper functioning under external atmospheric conditions.
