Abstract
The invention discloses a method for producing fuel ethanol by using the straws of sorghums; the straws of the sorghums after being crashed are dried into a raw material which is added with water for soaking and then added with high activity yeasts for liquor making; the raw material after inoculation is put into a fermenter, sealed, goes through fermentation at constant temperature, is cooled and then goes through secondary fermentation, thus obtaining the fuel ethanol after the completion of fermentation. The method stores the fresh straws of the sorghums after dehydration and drying, then produces the fuel ethanol by carrying out reconstituted fermentation, is not limited by seasons, has simple technique, short fermentation period and little investment and is applicable to the small-scale industrialized production and promotion in the rural areas of China.
Description
Technical field
The present invention relates to a kind of method of producing alcohol fuel, specifically refer to a kind of method of producing alcohol fuel with broomcorn straw.
Background technology
At present, because whole world fuel supply anxiety, each state is all developing bioenergy energetically.China is a large agricultural country, and the Chinese sorghum resource is very abundant, and the annual broomcorn straw that is produced just reaches 700,000,000 tons.But these resources are not fully used, and major part all is used for feeding animals or is burnt in the field.
The now existing report (patent of utilizing broomcorn straw to ferment to produce alcohol fuel: a kind of method 200710000636.6 of producing fuel ethyl alcohol by ferment), but because the seasonality that broomcorn straw is produced is too strong, only when Chinese sorghum is ripe, just can be utilized, so this method is difficult to realize suitability for industrialized production.This shows that the broomcorn straw storage is a hot research field.Existing report divides the horizontal heap of buttress, perpendicular stocking and storing to hide the good broomcorn straw of harvesting, but the time of this method storage be no more than 4 months, and sugar loss is serious.Seek a kind of can be with the broomcorn straw Long-term Storage, prolong the production phase of utilizing the broomcorn straw fermentation, zymotechnique is simple, the cycle is short, invest little method comes producing fuel ethyl alcohol by ferment to meet China's current demand.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method of producing alcohol fuel with broomcorn straw, and this method is with the broomcorn straw Long-term Storage, and prolongation utilizes its fermentative production phase to produce a kind of method of alcohol fuel.
Technical problem of the present invention is solved by following scheme: a kind of method of producing alcohol fuel with broomcorn straw, it is characterized in that: the disintegrating Chinese sorghum stalk is dried into raw material through 60-70 ℃, add doubly by the 3-5 of raw materials quality and to add water, soaked 0.5-3 hour, insert highly active dry yeast by 1 ‰-3 ‰ of raw materials quality again, then the above-mentioned raw material of planting of taking over is rendered in the mash-back, sealing, preceding 2-4 days interior in 28 ℃ of-30 ℃ of ferment at constant temperature, be cooled to 15-22 ℃ then and fermented 3-6 days again, distillation promptly gets alcohol fuel after the fermentation ends.
Advantage of the present invention is: adopt method of the present invention that fresh broomcorn straw is dehydrated the back storage, the rehydration producing fuel ethyl alcohol by ferment is not subjected to the restriction in season then; And technology is simple, fermentation period is short, investment is little, is applicable in China's rural area Small Scale Industry production to promote.

Embodiment
Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
(1) drying treatment of sweet sorghum stalk: pulverize the 900kg sweet sorghum stalk with pulverizer, be dried into raw material for 65 ℃ then, cryodrying place preservation;
(2) rehydration: take by weighing the raw material of 100kg, add 400kg water, soaked 1.5 hours;
(3) inoculation: activation medium is a 4kg sucrose, 50 premium on currency, pH nature; Bacterial classification is highly active dry yeast 0.2kg; Culture temperature during activation is 28 ℃; Activate after 3 hours insert above-mentioned in the raw material of immersion treatment;
(4) go into the bucket fermentation: throw in the above-mentioned material of planting of taking in mash-back, sealing in 28 ℃ of ferment at constant temperature, is cooled to 20 ℃ then and fermented 6 days again in preceding 3 days;
(5) fermentation ends distillation:, promptly obtain alcohol fuel with the distillation of the material after the fermentation ends.
(6) repeat comparison:, repeat eight months with dried sweet sorghum stalk repeating step every month 2,3,4,5.
The mensuration of physical and chemical index in the fermenting process: in the single batch fermentation process of above embodiment, ferment after 9 days, the reducing sugar utilization ratio reaches (film reagent titration measuring) more than 70% in the raw material, and transformation efficiency reaches 67%, spirituosity degree 3.45% in the fermentation groove liquid (gas-chromatography instrument method mensuration); Continuous nine months repeated experiments data variation is little.
Claims (1)
1, a kind of method of producing alcohol fuel with broomcorn straw, it is characterized in that: the disintegrating Chinese sorghum stalk is dried into raw material through 60-70 ℃, add doubly by the 3-5 of raw materials quality and to add water, soaked 0.5-3 hour, and inserted highly active dry yeast by 1 ‰-3 ‰ of raw materials quality again, then the above-mentioned raw material of planting of taking over is rendered in the mash-back, sealing, in 28 ℃ of-30 ℃ of ferment at constant temperature, be cooled to 15-22 ℃ then and fermented 3-6 days again in preceding 2-4 days, distillation promptly gets alcohol fuel after the fermentation ends.
