Problems solved by technology

[0007] Using the above method, compared with the secondary fermentation of the traditional saccharifying enzyme method, using its new fermenting agent instead of saccharifying enzyme, although the degradation rate of the waste starch has been improved to a certain extent, but because this new fermenting The conditions are relatively high, and constant temperature fermentation must be strictly controlled at 25°C to 27°C. The amount of material in the production process is large, and it is difficult to achieve material transportation and effective control of mass transfer and heat transfer during the fermentation process. It does not have a large-scale industry. Necessary conditions for chemicalization, this method is the same as the secondary fermentation of glucoamylase, it belongs to intermittent fermentation, and covers a large area (based on an annual output of 60,000 tons of waste, all of which are converted to produce waste wine, and the secondary fermentation of waste is used For the fermentation process, it is necessary to build 500 standard cellars of 3.8×2.5×2.8m, 8 to 12 standard distillation retorts, covering an area of ​​8,000 square meters; ℃~27℃, there are 300 fermentation towers or fermentation pits, 8~12 standard distillation retorts, and the investment cost is large). During the fermentation process, due to the continuous increase of alcohol concentration, it will affect the further progress of fermentation, resulting in the waste The conversion rate of starch is still low, the production efficiency of distilled grain liquor is low, and the production cost remains high

Abstract

The invention discloses a method for producing white wine by distilled grain continuous solid state fermentation; wherein the preparation of compound fungus liquid includes that diastatic enzyme, cellulase and dried yeast are mixed by parts by weight into compound ferment, warm water at 30-35 DEG C is added, and activation cultivation is carried out at normal temperature, thus obtaining the compound fungus liquid; inoculation includes that the compound fungus liquid and distilled grain after pre-treatment are mixed to be uniform under the conditions of sealing and temperature of 30-32 DEG C and then saccharified; fermentation extract includes the inoculated distilled grain is slowly delivered to a fermentation container at the temperature of 32-35 DEGC under the conditions of sealing and temperature of 30-32 DEG C, solid state fermentation is carried out on the distilled grain in the container, and fermentation product in the distilled grain is extracted by delivering carbon oxide into the fermentation container at regular flow from the moment that the distilled grain is placed into the fermentation container, and then normal pressure condensation is carried out to obtain distilled grain wine. The invention has the standing advantages that technological process is continuous, operation process is simple and quick, energy consumption is low, production cost is low, wine yield is high, distilled grain wine quality is good, and the method is applicable to large scale industrialized production.

Description

Background technique [0002] In the production of solid liquor in China, waste is an inevitable product. According to incomplete statistics, about 2 to 4 tons of waste will be produced for every ton of liquor produced, and the annual output of liquor waste in the country is more than 30 million tons. [0003] Waste grains is the main by-product of liquor production, which has high acidity, water content above 55%, and contains a large amount of crude fat, crude protein, crude fiber, crude starch, vitamins, various trace elements and nitrogen-free extracts, etc. , highly biodegradable, easily corrupted, inconvenient to store, if not disposed of in time, it will cause serious pollution to the ...
