Embodiment 1

[0019] A method for distilling alcohol by mixing straw cellulose dry matter with liquid alcohol fermentation mash, comprising the following steps:

[0020] Step 1: Using corn as a raw material, ferment for 50 hours to prepare a mature liquid alcohol fermented mash with an alcohol content of 11% and a residual sugar content of less than 0.5%; the liquid alcohol fermented mash is then mixed with acidified waste molasses to make the liquid The fermentable sugar content in the alcohol fermented mash is adjusted to 2%, to obtain mixture A;

[0021] Step 2: Crushing the cellulose dry matter of corn stalks with a moisture content of 14% into small pieces with a length of 5-10 mm to obtain raw material B containing cellulose dry matter of straw;

[0022] Step 3: Mix the mixture A obtained in step 1 with the raw material B obtained in step 2 at a ratio of 5:3 and put it into a stirring mixer for the first initial mixing with liquid yeast, and then enter the ribbon mixer to fully Mix e...

Embodiment 2

[0027] A method for distilling ethanol by mixing straw cellulose dry matter with liquid fermented mash, comprising the following steps:

[0028] Step 1: using dried cassava as raw material, fermenting for 58 hours to prepare a mature liquid alcoholic fermented mash with an alcohol content of 12.5% ​​and a residual sugar content of less than 0.2%; the liquid alcoholic fermented mash is then mixed with acidified waste molasses to make The fermentable sugar content in the liquid alcohol fermented mash is adjusted to 4%, to obtain mixture A;

[0029] Step 2: breaking the rice straw with a moisture content of 14% into small pieces of 1-5 mm, and then mixing the rice husks accounting for 10% of the rice straw to obtain the straw-containing cellulose dry matter raw material B;

[0030] Step 3: Mix the mixture A obtained in step 1 with the raw material B obtained in step 2 at a ratio of 5:2 and put it into a stirring mixer for the first initial mixing with liquid yeast, and then enter...

Embodiment 3

[0035] A method for distilling ethanol by mixing straw cellulose dry matter with liquid fermented mash, comprising the following steps:

[0036] Step 1: Using corn as raw material, ferment for 65 hours to prepare a mature liquid alcohol fermented mash with an alcohol content of 14% and a residual sugar content of less than 0.2%; the liquid alcohol fermented mash is then mixed with acidified waste molasses to make the liquid The fermentable sugar content in the alcohol fermented mash is adjusted to 4%, to obtain mixture A;

[0037] Step 2: crushing cotton stalks and dry bagasse with a moisture content of 14% into small pieces with a length of 5-20 mm in a ratio of 1:2, and then mixing them with sawdust to obtain dry material B containing straw cellulose;

[0038] Step 3: Mix the mixture A obtained in step 1 with the raw material B obtained in step 2 at a ratio of 5:2.5 and put it into a stirring mixer for the first initial mixing with liquid yeast, and then enter the ribbon mix...

Abstract

The invention discloses a method for distilling liquid alcohol fermented mash mixed with straw cellulose dry matters to prepare alcohol. The method comprises the following steps: 1, crushing straw and other dry matters containing cellulose into sections with length of 1-20mm to obtain a raw material B; 2, putting the liquid alcohol fermented mash and the raw material B into an auger mixer and primarily mixing with liquid saccharomycete, feeding into a spiral ribbon mixer for sufficiently uniformly mixing to obtain a mixture C; 3, putting the mixture C into a solid-state fermentation tank for fermenting to obtain solid-state fermented grains; 4, continuously feeding the solid-state fermented grains into an automatic continuous alcohol distilling machine to distill light alcohol; and 5, conventionally rectifying the light alcohol to obtain a finished alcohol product. The alcohol produced by adopting the process, no liquid distilled grains or sewage is discharged, the problems of hard control of pollution caused by liquid distilled grains and high alcohol production cost in the prior art can be solved, and the market requirement can be met.

Description

technical field [0001] The invention relates to the technical field of alcohol production, in particular to a method for distilling alcohol by mixing liquid alcohol fermentation mash with straw cellulose dry matter. Background technique [0002] At present, the technology of producing alcohol is mainly divided into two categories. The first category is the preparation of alcohol by liquid method, that is, starchy substances or waste molasses are used as raw materials, and the alcohol distillation waste liquid and liquid wine tank produced in the distillation process are difficult to treat. The environment has brought greater damage and pollution; the second type is the preparation of alcohol by solid-state method, that is, using sweet sorghum as raw material, solid-state fermentation produces alcohol, although there is no liquid wine tank discharge, but because the sugar content of sweet sorghum is not high enough, resulting in The production cost is too high; the third meth...
