Hypro BBT is designed in accordance with sound engineering practice and hygienic industry norms. The mechanical design of the tank is based on relevant ASME section VIII for dish shell & GEP. Where the code regulations are not precisely defined for a given situation, practical experience has been applied for. Process design (Heat transfer areas are based on a tailor-made computer-based program developed by our company & As per Hygienic Process Design & Practice.
Bright beer tanks are used in a brewery for following operations.
- Maintain the temperature of filtered /Bright Beer to –10 C
- Maintain CO2 counter pressure on beer in order to avoid CO2 loss
- Transfer beer under CO2 counter pressure to bottle/can filler
Young Beer from Unitank goes for the filtration process and then is filled in the BBT batch-wise. Young beer from unitank, at –10 C, and pressure at 1.5 bar, in this case, is transferred to filter section. Before beer comes in BBT, the inside pressure of BBT is kept under working pressure e.g. at 1 bar, and when the beer starts to come in pressure gets developed and excess pressure (e.g.in excess of 1.5 bar) will be vented out from the pressure safety valve on a tank top. However, it is advisable to maintain the pressure of @ 1 bar by manually throttling the valve on the CIP-gas line connected to the CO2 vent. This Beer is maintained at the same temperature i.e. – 10C. Considering some Heat Loss BBT is given a cooling jacket with glycol circulation.
This area is provided on the conical part & bottom part of the shell. Temperature is automatically maintained in the BBT by a PC-PLC based system. The control logic has been defined in the control logic document. In order to avoid CO2 loss, CO2 counter pressure shall be maintained during beer transfer to bottle filler.
