Abstract
The technological process of produce ethanol with sweet sorghum stalk includes the steps of: cleaning sweet sorghum stalk, crushing and squeezing juice, filtering and clarifying with added acid, fermentation, centrifugal separation, extracting ethanol, refining ethanol, etc. Using sweet sorghum stalk with high yield, high saccharide content and low processing cost as material can lower the production cost of ethanol.
Description
What the present invention relates to is a kind of production alcoholic acid new raw material and processing method, is to be raw material production alcoholic acid processing method with sweet sorghum stalk specifically.
Present existing production alcoholic acid raw material has starchy material, and saccharine material, cellulose raw material and synthetic method are produced ethanol.The shortcoming that above-mentioned all raw materials and producing and manufacturing technique exist has: 1. raw materials such as starchy material production ethanol, used corn, rice, wheat, potato class are ploughed and production restriction, can not use in a large number and the production cost height, the Processes and apparatus complexity, power consumption is high, water resources consumption is serious, and is seriously polluted etc.; 2. saccharine material is produced ethanol, used sugarcane, and planting costs such as beet are higher, and extensively model plantation, and sugarcane can only be in China's south plantation, and beet can only be at north; 3. cellulose raw material is because production cost is too high, and China's cellulose raw material of no use is basically produced ethanol; 4. the synthetic method is produced the ethanol product that consumes petroleum, and China's this method also of no use is basically produced ethanol.
Purpose of the present invention for the deficiency of improving prior art provide a kind of can be a large amount of, produce the alcoholic acid raw material at an easy rate and be sweet sorghum stalk and produce the ethanol method.
In order to reach purpose of the present invention, the invention provides following technical scheme: the sweet sorghum stalk is produced the ethanol method, comprise that sweet sorghum stalk cleaning-stalk broken juice-filtration adds an acid clarification-alcohol-centrifugation-load and gets ethanol-ethanol and make with extra care, it is characterized in that: this processing method, use the sweet sorghum stalk to be raw material, through being squeezed the juice by broken, fermentation juice is produced ethanol.
Sweet sorghum stalk of the present invention is produced ethanol method and feature and is also that the sweet sorghum stalk cuts and cuts into chunks, and mixes the sort of quyi and directly sends out alcohol and produce ethanol.
The present invention produces ethanol and compares with present existing production ethanol method, following advantage is arranged: (1) is compared with starchy material: the yield per unit height, 1 mu of sweet sorghum stalk can be produced about 90% ethanol 500kg, and by-product utilization is worth very high, and one mu of the highest of starchy material such as corn, rice or potato class is produced the following ethanol of 300kg; (2) processing unit is simple, because no starchy material is produced the required saccharification treatment facility of ethanol, equipment reduces more than 20%; (3) power consumption is low, and energy output and input ratio are 25: 1, and starchy material is produced alcoholic acid energy output and the input ratio is 5: 1; (4) substantially anhydrous resource consumption, the water owing to containing in the sweet sorghum stalk juice about 70% need not to add water and can send out alcohol; (5) pollute gently, starchy material is produced the BOD value that contains in the poor water of alcoholic acid greatly about every liter of 25000-35000 milligram, and sweet sorghum stalk juice is produced the alcoholic acid water that is pickled with grains or in wine and contained the BOD value and have only every liter of 5000-10000 milligram.
With sugarcane, saccharine materials such as beet are compared, and (1) planting range is more extensive, and latitude 5-55 degree all can be planted; (2) sweet sorghum less demanding to sunlight temperature, soil, moisture content, fertilizer, can extensively plant, planting cost is lower, sowing time is long, all can plant in regional 3--7 month China is most of, about 120 days production phases, so be planted in China's arid, semiarid zone and the areas with soil-erosion problems plantation of sweet sorghum acquire a special sense; The luminous energy output is not produced the alcoholic acid raw material, can also play the effect of forest in season.
Produce ethanol with cellulose raw material and compare, production cost reduces greatly.Produce ethanol with synthesis method and compare, promptly reduced cost, do not strive petroleum products again with other industry, and for petroleum industry has increased new fuel, as: ethanol petrol, ethanol diesel fuel etc.In sum, the sweet sorghum stalk is produced ethanol, and raw material is that cost is low, pollute few, can be in a large number and produce ethanol at an easy rate.Technical process of the present invention is: the cleaning of sweet sorghum stalk, and---the stalk broken juice---filtration adds the acid clarification, and------make with extra care in centrifugation---load is got ethanol---in fermentation by ethanol.
Example one:
With fresh (being no more than 48 hours) sweet sorghum stalk 100kg from gathering in processing, remove topping, blade root system and earth, broken juice, the 95kg that must squeeze the juice (contain and wash marc 15kg water), 200 mesh filter screens filter, and add 30% hydrochloric acid 1kg, clarified 24 hours, get supernatant liquid 90kg, the turbid liquid of lower floor is sneaked into juice extractor and is pressed, adds distillery yeast, fermented 72 hours, distill 80% alcohol 14.5kg
Example two:
With fresh sweet sorghum stalk 100kg, remove blade tip, root system and earth, be cut into the 1-3cm segment, add the distillery yeast 30kg that has brought back to life, mix thoroughly, fermented 120 hours, straight run distillation gets 80% ethanol 15kg.
Example three:
With fresh sweet sorghum stalk 100kg, the 1-3cm segment is cut in cleaning, adds distillery yeast, mixes fermentation 120 hours thoroughly, squeeze the juice distill 80% ethanol 17.8kg.
Claims (3)
1, the sweet sorghum stalk is produced the ethanol method: comprise that sweet sorghum stalk clears up a stalk broken juice one and filter and add acid clarification one fermentation one centrifugation one to extract ethanol one ethanol refining.It is characterized in that: adopting fresh sweet sorghum stalk is raw material, through broken juice or operation such as the fermentation of not squeezing the juice produce ethanol.
2, sweet sorghum stalk according to claim 1 is produced the ethanol method, and it is characterized in that: with fresh sweet sorghum stalk is raw material, cuts into chunks through cutting, and fermentation, distillation slag extract ethanol.
3, produce the ethanol method according to the described sweet sorghum stalk of claim 1, it is characterized in that the sweet sorghum stalk juice of squeezing the juice, ferment uses sap extraction ethanol again.
