Description
Technical field
The present invention relates to a kind of is the alcohol crossed circle manufacturing technique of main raw material with the potato class, belongs to fermentation alcohol industrial technology field.
Background technology
Starchy material fermentative production alcohol is one of main method of Alcohol Production.In traditional starchy material fermentation producing wine Seiko skill, size mixing by water through pulverizing, adding for starchy material, liquefaction and saccharification, inoculate then the distillery yeast fermentation (as " alcohol industry handbook one book is introduced, volumes such as Zhang Kechang, light industry press).The average alcohol per ton of traditional zymotic production technique will discharge 12～15 tons of useless mash, useless mash COD
CrMore than 40000～50000mg/L, not only cause serious water resource pollution, also cause a large amount of wastings of resources.
Existing Alcohol Production method of wastewater treatment mainly contains: the concentrate drying method is produced DDGS and first anaerobically fermenting and is produced behind the biogas aeration aerobic treatment etc.The concentrate drying method is produced DDGS and is had problems such as investment is big, working cost height.This method processed waste water energy qualified discharge, but still need to drop into certain working cost, therefore, the concentrate drying method is produced DDGS and is had good social benefit, and does not have economic benefit.Elder generation's anaerobically fermenting produce subject matter one that the method for aeration aerobic treatment behind the biogas exists be take up an area of big, investment is high, the 2nd, later stage aeration aerobic treatment has only to drop into does not have output, the waste water treatment cost of Alcohol Production per ton up to 20 yuan about, the 3rd, waste water treatment is difficult to thoroughly, the waste water COD of discharging
CrStill about 500mg/L.The technology that adopts slops recycle to extinction batching is also arranged, but owing to contain a large amount of organic acids in the useless mash of the distillation after the zymamsis, the pH value is between 3.0～4.0, cause Ye Huamei can not normally bring into play vigor (the suitableeest action pH value of Ye Huamei is between 5.5～6.5) when preparing burden the back liquefying starchiness raw material, cause cost too high, and circulation is batch limited, and a large amount of high-concentration wastewater emission are still arranged, and this method does not adopt on commercial production scale.
Chinese patent application number: 200610097623.0 disclose denomination of invention is: be the alcohol annular production technique of main raw material with the potato class, obtained good effect, but the suitableeest action pH value of saccharifying enzyme is between 4.0～4.5 during owing to saccharification, therefore, after liquefaction finishes, need mineral acids such as additional sulfuric acid or hydrochloric acid to adjust the acidity of liquefier, make its pH value between 4.0～4.5, could add the saccharifying enzyme saccharification.Add mineral acid and not only increased production cost, and, the acid ion that mineral acid is brought into also can influence the anaerobically fermenting of the useless mash of later stage distillation, and contain a large amount of organic acids in the useless mash of distillation, part slops direct reuse is as the acid adjustment water, the alternative mineral acid that adds has better economical effectiveness.
Useless mash reuse of part distillation of the present invention and the described reuse of existing patent are essentially different, in the existing patent, partly or entirely the useless mash of distillation is as process water, get back to ingredient station, and the useless mash of the distillation of the part among the present invention is got back to saccharification workshop section, as the acid adjustment water, variation has all taken place in reuse purpose and reuse means.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, is the alcohol crossed circle manufacturing technique of main raw material thereby provide a kind of with the potato class, and the useless mash of its distillation only needs one step of anaerobically fermenting to handle, and has significantly reduced floor space and investment in fixed assets; Anaerobically fermenting Digestive system reusable edible can be realized the zero release of fermentation waste water, realizes the water resources recycle; The useless mash of part distillation can be got back to saccharification workshop section, can be used as the acid adjustment water, and also can reduce the Alcohol Production cost.
Main solution of the present invention is achieved in that
The present invention is the following processing step of alcohol crossed circle manufacturing technique employing of main raw material with the potato class:
1, getting starch mixes with last batch anaerobically fermenting Digestive system; Starch and last batch anaerobically fermenting Digestive system ratio of mixture are 1: 1.7～3.0;
2, add the Ye Huamei post-heating that stirs, liquefaction is cooled to 58～65 ℃;
3, add the useless mash of batch distillation in the liquefier after cooling, the useless mash add-on of distillation is 10～30% of a liquefier, pH value with mixed solution behind the useless mash of adding distillation is as the criterion between 4.0～4.5: add the saccharifying enzyme saccharification again, saccharification is cooled to 25～40 ℃ after finishing, the access distillery yeast that spreads cultivation, constant temperature culture fermentation 36～72 hours;
4, after the fermentation ends, obtain finished product alcohol through distillation;
5, get following batch of saccharification acid adjustment water of 5～25% conducts of the useless mash total amount of distillation, all the other useless mash are cooled to 50～80 ℃, insert Shang batch active sludge constant temperature anaerobically fermenting and produce biogas;
6, anaerobic fermented liquid reclaims active sludge and Digestive system through solid-liquid separation again, and Digestive system returns burden process and makes the technology water, circulation successively, and the pH value rises to 6.5～7.0 in the Digestive system,
Described Ye Huamei adopts α-Dian Fenmei; The Ye Huamei add-on is: 6～15U/g starch, and the liquefaction Heating temperature is: 80～105 ℃; Liquefying time is: 50～120 minutes;
Described saccharifying enzyme adopts the general goods saccharifying enzyme; The saccharifying enzyme add-on is: 80～150U/g starch, and saccharification temperature is: 58～65 ℃; Saccharification time is: 0～60 minute;
The described distillery yeast access amount that spreads cultivation is 8～12% of a saccharification liquid:
Described starchy material is sweet potato powder or Tapioca Starch etc.
Compared with the prior art the present invention has the following advantages:
The useless mash of tart distillation is through behind the anaerobically fermenting among the present invention, and the organism such as organic acid in the useless mash are degraded to biogas, and the pH value of Digestive system rises, and has guaranteed that the reuse batching of Digestive system can not exert an influence to operations such as liquefaction, saccharification, fermentations; The useless mash of distillation only needs one step of anaerobically fermenting to handle, and has significantly reduced floor space and investment in fixed assets; Do not have fermentation waste water and enter the high aeration aerobic treatment of running cost, and the running cost of anaerobically fermenting is low, the useless mash of distillation of adding alcohol per ton can produce 350m
3The active sludge (can process about 300 kilograms of compound bio matter fertilizers) of the biogas about (mark attitude) (amounting to 350 kilograms of commercial coals approximately) and 200 kilograms, therefore, this technology has good economic benefit; The recycle of anaerobically fermenting Digestive system realizes the zero release of fermentation waste water, does not have fermentable discharge of wastewater, and has saved a large amount of precious water resource; The useless mash direct reuse of part substitutes the mineral acid in the traditional technology, has not only reduced the Alcohol Production cost, also basically eliminate SO
4 -2Deng mineral ion to the issuable inhibition phenomenon of anaerobically fermenting.
