Abstract
The invention discloses a method for making alcohol from straws, which comprises the following steps: 1. selecting high-quality corn straws, and cleaning; 2. adding corn cob, rice hull, cottonseed hull and sunflower residue as a composite base material; 3. pulverizing the mixture to 145 meshes; 4. hydrolyzing the mixture with distilled water; 5. boiling the hydrolyzed mixture in an iron pan; 6. cooling; 7. diastatic fermentation: fermenting the cooled mixture in a ceramic cylinder with the diameter of 1.5m; and 8. distilling and extracting. The invention provides a novel method for producing alcohol from corn straws, and has the advantages of short development process, high efficiency and low energy consumption, thereby lowering the alcohol production cost and widening the straw application range.

Technical field
The present invention relates to stalk application, particularly relate to a kind of method of utilizing stalk to make alcohol.
Background technology
Alcohol is a kind of important industrial raw material, be widely used in food, chemical industry, medicine and other fields, it is replacing gasoline partly or entirely, there is the advantages such as safety, clean, regeneration, alcohol mainly be take molasses, potato class, cereal as fermenting raw materials production, mainly take corn as raw material, due to population growth and Alcohol Production Cost Problems in China northeast, the corn of take is hard to carry on as raw material production alcohol, and utilizes abundant, cheap maize straw to become inexorable trend for raw material production alcohol.
I am after at present still lower aspect straw utilization rate, general maize straw is except small part is utilized, most of with direct impouring environment of form such as accumulation, waste burnings, causes very big pollution and waste, and the method thermo-efficiency of this direct burning is very low, very large waste stalk resource.Maize straw is mainly Mierocrystalline cellulose, hemicellulose and wooden element, after pre-treatment and hydrolysis, can decompose saccharogenesis, is the favourable resource of making alcohol.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of method of utilizing stalk to make alcohol, thereby have the producing alcohol by using maize straws novel method that the flow process developed is short, efficiency is high, energy consumption is low, reduces Alcohol Production cost, has expanded stalk use range.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of method of utilizing stalk to make alcohol is provided, comprises the following steps:
Step 1: choose the maize straw of high-quality, then clear up the impurity such as silt, stone of maize straw the inside; Step 2: add corn cob, rice hulls, cotton seed hulls, Sunflower Receptacle slag as composite base-material;
Step 3: first maize straw is put into iron hammer pulverizer and pulverized, reach 150mu, then the corn cob in composite base-material, rice hulls, cotton seed hulls, Sunflower Receptacle slag are added successively in pulverizer and carry out co-grinding, reach the compound of 145mu;
Step 4: hydrolysis, with distilled water, compound is soaked and is hydrolyzed for 6～7.5 hours;
Step 5: iron pan boiling, the compound after hydrolysis is put into iron pan and carry out boiling, in pot, put into calcium oxide and soften;
Step 6: cold lack, by compound pull out put on cooling table, carry out cooling fast;
Step 7: diastatic fermentation, it is the ceramic cylinder of 1.5 meters that the compound after cold lack is put into diameter, keeps one deck compound to add distiller's yeast one time during placement, until ceramic cylinder is filled out at 4/5ths o'clock, and cylinder body seal is tight, ferment 5～6 days;
Step 8: distillation extraction, take out after waiting the fermentation of compound in ceramic cylinder, put into distiller and distill, 65%～85% the alcohol that can make.
In preferred embodiments of the present invention, in described step 3, compound is set to by weight percentage: corn cob 10%～15%, rice hulls 5%～10%, cotton seed hulls 2.5%～5.5%, Sunflower Receptacle slag 15%～20%, maize straw 65%～75%.
In preferred embodiments of the present invention, the calcium chloride of putting in pot in described step 5 accounts for 5% of compound.
In preferred embodiments of the present invention, described step 6 adopts air-cooledly carries out coolingly, and the described air-cooled time is in 30min clock.
In preferred embodiments of the present invention, in described step 7, the bed thickness of compound is 15cm.
The invention has the beneficial effects as follows: a kind of method of utilizing stalk to make alcohol, reduces Alcohol Production cost, has expanded stalk use range thereby have the producing alcohol by using maize straws novel method that the flow process developed is short, efficiency is high, energy consumption is low.
