METHOD FOR PRODUCING RECTIFIED ALCOHOL Russian patent published in 2016 - IPC C12P7/06 

FIELD: food industry.

SUBSTANCE: according to the method wort distiller plant includes a digestion column operating at high pressure, epuration, distillation, booster and preliminary purification column operating under atmospheric pressure, and final purification column, concentration of methanol and head impurities alcohol column, in which pressure is below atmospheric pressure. Note here that digestion column is supplied by supplying the top plate with the residue of alcohol column heated by extraction column and heating steam condensate from the epuration boilers, distillation, extraction, distillation columns. Initial wort is heated in heat exchangers by heat of extraction and epuration columns, as well as in wort heater by heat steam condensation with upper plate of epuration column. Deep purification of ethyl alcohol cleaning from impurities is carried out in the epuration and booster columns which have refinery, digestion and concentration parts and operate with supply of hydraulic selection water onto the upper plate.

EFFECT: invention allows to manufacture a high quality product at a reduced cost.
