Abstract
The invention discloses a process for ethanol production from dining and kitchen waste. The industrial ethanol is obtained by enzymolyzing the biological dining and kitchen waste, centrifugal separating, regulating sugar degree and pH value, high temperature sterilizing, inoculating for fermentation, anaerobic fermenting, steaming purification. The process has mild production condition, low energy consumption, no secondary pollution is included, decontamination, reduction and recycling of the dining and kitchen waste are realized.
Description
Technical field
The present invention relates to waste resource regenerative use technology field, particularly kitchen castoff recycling technology is specifically related to a kind of kitchen castoff manufacture alcoholic acid method of utilizing.
Background technology
The city kitchen castoff has high grease, high protein, nutritious, perishable rotten characteristics, its major ingredient has materials such as starch, Mierocrystalline cellulose, protein, lipid, also contain trace elements such as calcium, magnesium, potassium, iron simultaneously, owing to deal with improperly and make kitchen castoff be used for feeding the rubbish pig, refine trench wet goods phenomenon and remain incessant after repeated prohibition, cause huge hidden danger for health and epidemic prevention and food safety and environmental pollution, so kitchen castoff is necessary to carry out individual curing all the time.
Handle at present both at home and abroad changing food waste the most widely method be through after the simple process as feed or directly carry out landfill disposal, therefore fail to make the kitchen castoff resource to carry out maximum using, utilizing biological treatment and additive method that wherein active substance is carried out trans-utilization just has important practical sense.
Energy dilemma has become the important factor of restriction Economic development; in order to alleviate oil pressure; China has just begun pilot program to alcohol fuel in the beginning of this century; the raw material of fermentative Production alcohol fuel mainly is starchiness and saccharide raw material at present; but starch materials is ploughed and production restriction; production cost is high, and planting costs such as saccharide raw material such as sugarcane, beet are higher, and are subjected to the restriction of region and weather.In order to reduce cost, the cellulose family raw material more and more comes into one's own, as patent CN1442483A, CN1283701A, CN1511954A is that fermenting raw materials is produced ethanol with paddy, stalk etc. respectively, but the biomass waste of this fiber-like is difficult to hydrolysis, therefore, though above-mentioned patent is both economical on raw material, also be difficult to scale operation at present.Patent CN1948498A has invented a kind of technology with producing fuel alcohol by kitchen garbage fermentation, this technology utilization glucoamylase carries out saccharification to kitchen castoff to be handled, connect saccharomycetes to make fermentation then and produce ethanol, yet except starchy material, also contain nutritive substances such as cellulose family, protein in the kitchen castoff, only being hydrolyzed with amylase can not be with the whole hydrolysis of the nutritive substance in the kitchen castoff, also be a kind of waste of resource, so the present invention has showed special advantages from the angle of the cost and the utilization of resources.
Summary of the invention
The invention provides a kind of kitchen castoff manufacture alcoholic acid method of utilizing, its working condition gentleness, energy consumption is low, non-secondary pollution.
Technical scheme of the present invention is:
(1), kitchen castoff is sorted, abiotic matter waste is wherein picked out the recovery of classifying;
(2), through the letter sorting after biomass waste mix with water, add amylase, saccharifying enzyme, proteolytic enzyme and cellulase then and carry out enzymolysis, temperature remains on 50-60 ℃, time 2-4h;
Every gram biomass waste adds amylase 6-10U, saccharifying enzyme 50-200U,, proteolytic enzyme 20-50U, cellulase 20-50U;
(3), carry out behind the enzymolysis centrifugally, be protein fodder behind the dry solid substance residue, liquid is enzymolysis solution;
(4), detect the pol and the pH value of enzymolysis solution, and these two parameters are adjusted, the adjustment pol is 10-12%, the pH value is 5-7;
(5), carry out high-temperature sterilization then;
(6), then inoculate yeast saccharomyces cerevisiae and carry out anaerobically fermenting, inoculum size is 8-10%, and leavening temperature 30-34 ℃, fermentation time 60-72h makes at last and contains 8%-10% alcoholic acid fermented liquid;
(7), ethanol is purified: the alcoholic acid fermented liquid is distilled purification, obtain the industrial alcohol product.
Working condition gentleness of the present invention, energy consumption is low, and non-secondary pollution has been realized innoxious, minimizing, the resource utilization of kitchen castoff.
Embodiment
(1), kitchen castoff is sorted, abiotic matter waste is wherein picked out the recovery of classifying;
(2), through the biomass waste after the letter sorting and water with 1: 1 mixed, add then that amylase, saccharifying enzyme, proteolytic enzyme, the amount of cellulase of 6U, 50U, 20U, 20U are added respectively according to every gram biomass waste, heating, temperature remains on 50 ℃, time 4h;
(3), carry out behind the enzymolysis centrifugally, be protein fodder behind the dry solid substance residue, liquid is enzymolysis solution;
(4), detect the pol and the pH value of enzymolysis solution, and these two parameters are adjusted, the adjustment pol is 10%, the pH value is 6;
(5), carry out high-temperature sterilization then;
(6), then inoculate yeast saccharomyces cerevisiae and carry out anaerobically fermenting, inoculum size is 8%, 30 ℃ of leavening temperatures, and fermentation time 60h makes at last and contains 8% alcoholic acid fermented liquid;
(7), ethanol is purified: will contain 8%-10% alcoholic acid fermented liquid and distill purification, and obtain the industrial alcohol product.
