The invention discloses a method for accelerating aging of liquor by circulating utilization of
distillation cooling water of the liquor, relating to the technical field of
brewing. A device is as follows: a liquor cooler is arranged in a water tank of a cooler, a steam
pipe is arranged at the bottom end of a liquor
distillation device, the liquor
distillation device, the liquor cooler, a liquor aging tank and a liquor
storage tank are fixed through a liquor pipeline, a
heat exchanger is arranged in the liquor aging tank, a water inlet
pipe is inserted into the water tank of the cooler, and the water tank of the cooler, a transfer tank A, the
heat exchanger, a transfer tank B and the water tank of the cooler are fixed through a
water pipe. A method is as follows: injecting the cooling water, distilling fermented grains, condensing liquor steam, circulating the cooling water from the water tank of the cooler to the transfer tank A to the
heat exchanger to the transfer tank B to the water tank of the cooler, and keeping the heat exchanger at the temperature of 50-60 DEG C to always keep the aging temperature of the liquor in the liquor aging tank at 40-50 DEG C so as to be conductive to aging of the liquor and storage of the liquor in a constant-temperature state with molecular association. The method is used for accelerating the aging of the liquor. The method has the advantages of scientific and reasonable concept and structure, and stable and reliable method effects.
