This systerm located between the whirlpool tank and heat exchanger. Including one vacuum air pump,vacuum air tank, wort pump,secondary steam condenser and Siemens PLC control system.Work pressure-0.07Mpa.
Adopt stainless steel 304. Inner polish 0.4μm.The start of this system is use the vacuum air pump to keep the vacuum. After the steam start, use the second steam condenser keep the vacuum degree ,the vacuum air pump no need to work continuous. At the same time,the brewing water condensable second steam absorbed the heat of second steam and the temperature rises ,it is used as saccharificatiom hot water to supplement the reduced hot wort because of wort cooling.
