Abstract
The invention relates to a method for producing fuel ethanol by sweet sorghum straws, and the process flow comprises the following steps: 1. squeezing sweet sorghum straws by a squeezer; 2. mixing alcohol yeast with warm water with a temperature of 30 DEG C, and performing activation for 1-2 hours; 3. adjusting the total sugar concentration of sugar juice to be 17-20%, adding a nitrogen source, a phosphorus source, and a preservative with an adding amount of 0.1-0.2% on a basis of dry yeast, performing fermentation in a fermentation tank at 28-33 DEG C for 45-60 hours; 4. performing distillation by a simple ethanol distillation tower; 5. when the ethanol concentration reaches more than 70%, transferring the liquid to a multistage rectifying tower for continuous distillation so as to obtain high-concentration ethanol. The beneficial effects of the invention are that: sweet sorghum straws are used for fuel ethanol production by fermentation, which, on one hand, adds alternative energy of fuel ethanol which is free of pollution and is environment-friendly, and on the other hand, saves food, makes full use of agricultural resources, and reduces production cost.
Description
Technical field
The present invention relates to energy field, a kind of sweet Chinese sorghum pole is produced the method for alcohol fuel specifically.
Background technology
Sweet sorghum claims again sugared Chinese sorghum, is a mutation for common grain sorghum.It is the same with grain sorghum, and output is high, and its advantage is one mu of cane that can produce up to 4-5 ton sugar degree 17-21%.Sweet sorghum plant is up to more than 4 meters, 3.2 times of left and right that the output of the carbohydrate of synthesized is general corn.Waterlogging, drought-enduring, Salt And Alkali Tolerance, adaptability is extremely strong, anti-more than 10 ℃, and accumulated temperature reaches the area of 2600-4100 ℃ and all can cultivate.
In order to develop substitute energy, State Planning Commission has set up specially and has promoted the use of vehicle-use alcohol gasoline work leading group, and popularizes use vehicle-use alcohol gasoline in an all-round way with announcing Tenth Five-Year Plan Period at the beginning of calendar year 2001.But from economic benefit angle, consider, with grain, manufacture alcohol fuel cost too high, and can increase the weight of pressure.
Summary of the invention
The object of this invention is to provide a kind of sweet Chinese sorghum pole and produce the method for alcohol fuel.
Technical scheme of the present invention is: a kind of sweet Chinese sorghum pole is produced the method for alcohol fuel, and its technical process is
1, sweet sorghum syrup squeezing: adopt squeezing machine that sweet sorghum is squeezed;
2, activated yeast: distillery yeast is mixed to activation 1-2h with 30 ℃ of warm water;
3, syrup fermentation: the total sugar concentration of syrup is adjusted to 17-20%, adds auxiliary, by dry yeast, its addition is 0.1-0.2%, in fermentor tank in 28-33 ℃ of fermentation 45-60h;
4, ethanol simple distillation: adopt easy ethanol distillation tower to distill;
5, professional rectifying: adopt Multistage rectifying tower continuous still battery, obtain high concentration ethanol.
Preferably: described auxiliary has nitrogenous source, phosphorus source, sanitas.
Preferably: during described ethanol simple distillation, alcohol concn need reach more than 70%.
Usefulness of the present invention is: adopts sweet sorghum to carry out producing fuel ethyl alcohol by ferment, increased the alternative energy on the one hand, and alcohol fuel is pollution-free, and environmentally friendly; On the other hand, save food, make full use of agricultural resource, reduced production cost.
