Problems solved by technology

Using grain crops as raw materials to produce ethanol energy consumes a large amount of grain, which is the foundation of the national economy. Today, when the world's grain production is insufficient, using a large amount of grain as raw material to produce ethanol is not conducive to people's lives and the national economy development, unreasonable use of resources

Embodiment 1

[0013] Embodiment 1 The method for producing ethanol with sweet sorghum stalks has the following steps:

[0014] 1, get the sweet sorghum stalk, remove the ear and the root of the sweet sorghum stalk, cut the sweet sorghum stalk that removes the ear and the root into 15 mm sections, obtain raw scrap;

[0015] 2. Add water to the raw crushed material, adjust the sugar content to 17.5%, put it into the fermentation tank, control the temperature of the material in the fermentation tank at 30°C, adjust the pH value to 4.3, and obtain the liquid material;

[0016] 3. Add alcoholic yeast in the liquid material, the weight of the alcoholic yeast is 1.0‰ of the sweet sorghum stalk weight, stir evenly, and obtain the inoculated liquid material;

[0017] 4. Ferment the inoculated liquid material at a temperature of 30°C for 52-72 hours to obtain fermented mash;

[0018] 5. Distill the fermented mash in a distillation tower to obtain ethanol with a volume concentration above 95%.

Embodiment 2

[0020] Embodiment 2 The method for producing ethanol by mixed fermentation of sweet sorghum stalk and sweet sorghum has the following steps:

[0021] 1. Take the sweet sorghum stalk, remove the ears and roots of the sweet sorghum stalk, and cut the sweet sorghum stalk with the ears and roots into 10-20 mm sections to obtain raw scrap;

[0022] 2. Add water to the raw crushed material, adjust the sugar content to 17%-18%, put it into a fermenter, control the temperature of the material in the fermenter at 28°C-32°C, adjust the pH value to 4.2-4.5, and obtain a liquid material;

[0023] 3. Add alcoholic yeast into the liquid material, the amount of alcoholic yeast is 0.8‰~1.2‰ of the weight of sweet sorghum stalk, stir evenly, and obtain the inoculated liquid material;

[0024] 4. Take sweet sorghum grains, crush sweet sorghum grains into sweet sorghum noodles above 20 mesh, prepare sweet sorghum noodle water slurry according to the weight ratio of sweet sorghum noodles and wate...

Abstract

The invention is a method for making alcohol with sugar grass stalks, comprising the steps of: (1) taking sugar grass stalks and removing fringes and roots and cutting into 10-20 mm long sections; (2) placing these sections into fermenting cylinder and adding in water, regulating sugar content, temperature and pH value and obtaining liquid material; (3) adding distillery yeast in the liquid material, uniformly blending and obtaining inoculating liquid material; (4) fermenting the inoculating liquid material at 28deg.C-32deg.C for 52-72 h, and obtaining fermented mash; and (5) distilling the fermented mash in distilling tower and obtaining alcohol with a volume concentration of 95% above. And the sugar grass is a high energy crop, easy to plant, and is a new energy source raw material, according with the requirements for circulating economy and sustainable development.

Description

technical field [0001] The invention relates to a method for producing ethanol, in particular to a raw material for producing ethanol. Background technique [0002] As an important chemical raw material, ethanol is widely used in various fields of national economy, especially ethanol has no harmful gas emission after combustion, so it is a kind of pollution-free clean energy. The current energy sources are mainly mineral energy such as coal and oil. Mineral energy resources are limited. As people continue to exploit and use them, mineral energy will gradually decrease or even become exhausted. Ethanol can be produced by fermenting crops containing sugar or starch. It is a renewable energy source. Using crops as raw materials to produce clean energy meets the requirements of environmental protection and circular economy and sustainable development. In the prior art, the raw materials of agricultural crops when producing ethanol by fermentation are mainly food crops such as c...
