SUBSTANCE: method involves the isolation of 60-90% mash condensates, their dilution to 30-50% before feeding to a fractionating column, additional purification on the column filled with sorption material followed by feeding to rectification, vapor condensation which were taken from column top in multisection dephlegmator. Part of condensate from the first dephlegmator sections is divided for two flows one of which is removed for processing and another is recovered to the column. Condesate formed in the last dephlegmator sections is recovered to a fractionating column and ready product is removed as vapors from the bottom part of column. EFFECT: improved method of alcohol production. 2 cl
