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...
