Patent abstract
A method includes operating an apparatus having a mash circulating and recirculating system with pump and fermentation tank, an atmosphere circulating and recirculating system with blower for recirculating atmosphere between the tank and an ethanol-removal station, and an integrated refrigerating heat-transfer system with first coils remote from the tank for condensing out ethanol from the atmosphere, and second coils for warming the mash. The entire apparatus can be up-sized or down-sized for specific applications. In one form, the system includes electrically-driven pump, blower, and refrigeration compressors, with the external energy consumption being entirely electrical and kept surprisingly low.
