(CN103173500) 1. One method of making ethanol using persimon, ingredients: Mature persimon 60%-78%; tap water 10%-20%; black koji mold 0.05%-1%; edible alkali 0.1%-2%; citric acid 0.01%-0.5%; gelatin 0.1%-2%; calcium oxide 10%-20%; Its production process step is: (1). Astringent: will persimon clean, warm water at 40 degrees for 24 hours soaking, removing astringency; (2). Crushing: stainless steel crusher, will be broken up into a thick persimon persimon stock solution; (3). Filter: a coarse mesh to the inside of the dope impurities such as persimon terrier and nuclear, filtered to remove; (4). De-tannin: adding an edible base, and the tannin destroyed, insoluble substance being insoluble in water, filtered out; (5). Sugar: stock solution was diluted with water to the sugar content is twelve of the persimmon liquid persimon; (6). Adjusting acid: was adjusted to pH 3 with citric acid and the PH of the persimmon liquid; (7). Tempering: adjust the temperature to 34 degrees, and the incubation continued for 120 hours; (8). Fermentation: after detecting the respective indicator members meet the criteria, in an agitated state, the addition of five percent of yeast, yeast necessitating "wake-up", formulated using the yeast slurry; Method of preparing the yeast was brought into yeast are cultured in warm water at 34 for three hours; (9). Fermentation management: once per day for up and down the fermentation broth, the fermentation is more uniform; not intermittently observed temperature change of the fermentation broth, the best temperature is 34; Is not intermittent detection of the fermentation broth sugar content and alcohol content, sugar content 1% and the alcohol content when 10%, end of fermentation; (10). Distills crude liquid: broth filtration of the fermentation end of the press, the crude liquid was put forth; (11). Distillation: the green liquor subjected to a distillation column, is subjected to distillation, to obtain ninety-five percent ethanol; (12). Distillation: a distillation device, and the step (11) obtained ethanol content is increased to 99.5% or more; (13). Purified: the step with a calcium oxide (12) further purifying the ethanol obtained, to produce a fuel ethanol.
