ETHYL ALCOHOL PRODUCTION PROCESS Russian patent published in 1999 - IPC

Abstract RU 2138555 C1

FIELD: alcohol production. SUBSTANCE: starch-containing stock is ground for preparing aqueous suspension, which is thermally treated and saccharificated. Resultant wort is cooled, fermented, and distilled. According to invention, above- mentioned aqueous suspension is dispersed at 60-65 C on rotor-pulsation apparatus in stator-rotor gap at speed gradients from 3,5×105 to 4,5×105 n/s m. Subsequent heat treatment is conducted at 80-90 C for 20-30 min. EFFECT: increased yield and quality of alcohol. 1 dwg, 1 tbl, 4 ex
