Abstract

The invention provides an alcohol production process with high liquor yield. The alcohol production process comprises the following steps of S1, crushing dried sweet potatoes with skins into sweet potato starch, sieving by a 40-60-mesh sieve, taking oversize products and undersize products as raw materials for blending into powder syrup, and then preparing the powder syrup with water; S2, adding amylase into the powder slurry, and adding a stabilizer, then carrying out liquefaction treatment at 85-105 DEG C to obtain liquefied slurry; S3, adding saccharifying enzyme and xylanase into the liquefied slurry, and performing saccharification treatment at 50-60 DEG C to obtain saccharified slurry; and S4, adding a yeast material, alpha-amylase and a fermentation accelerant into the saccharified slurry for fermentation, and distilling the fermented mash to obtain the alcohol. The alcohol production process with high liquor yield has the advantages of high liquor yield and relatively low reducing sugar and residual total sugar content.

Description

technical field [0001] The invention relates to the technical field of alcohol, in particular to an alcohol production process with a high liquor yield. Background technique [0002] Alcohol is an important industrial raw material widely used in food, medicine, chemical industry, scientific research and other fields. At present, my country's alcohol production has achieved great development. Nowadays, the number of alcohol production enterprises is increasing continuously, and the annual output has ranked third in the world. However, many alcohol enterprises still use relatively traditional production processes, and the production process is far behind. The production level is advanced abroad, and the production efficiency is low and the cost is high. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides an alcohol production process with a high alcohol yield, which can increase the alcohol yield. The technical scheme adopt...
