Abstract
The invention relates to a method for preparing fuel ethanol by taking apple slag as raw material. It comprises following steps: (1) selecting apple slag got after apple juice production as raw material; (2) saccharifying: a. adding cellulase into apple slag (0.1- 1 active enzyme unit for every 1 g apple slag), stirring evenly, saccharifying at constant temeprature 45 Deg. C for 24 hours; b. adding water for immersion and filtering: adding warm water with its amount 2 times of that of saccharified apple slag, immersing at 30 Deg. C for 2 hours, filtering and getting clean sugar solution, the sugar content is 10 -13%, (3) fermenting: taking distillery yeast as bacteria, the inoculation is 10%, anaerobic fermentation at 30 Deg. C for 5 days; (4) distilling. The invention is characterized by enlarged raw material for fuel ethanol production, solution of server environmental pollution caused by fruit slag, and good economic and social benefit.
Description
Technical field
The present invention relates to a kind of is the method for raw material liquid producing fuel ethyl alcohol by ferment with the apple residue.
Background technology
China is maximum in the world apple production state, produces 1200 ten thousand tons in fresh fruit per year, and the trend of increase is arranged.The apple processing industry also grows up thereupon, the apple residue biomass are processed the tankage (20%--35% that is about the apple amount) of industries such as can, fruit juice, jam and fruit wine as apple, total amount is very considerable, has 10% to carry out processing treatment at present approximately, and all the other are all discharged as refuse.Because wherein water content height (60%--70%), sugar and nutrition content height, thus the apple residue biomass very easily rotten, smelly, turn sour, living mosquito maggot, surrounding environment has been caused serious pollution.Have serious crisis and cause under the background of serious environmental pollution at traditional energy such as coal, oil etc., alcohol fuel is renewable with it, non-environmental-pollution, use technology advantage such as reach a standard enjoys government and society to pay attention in motor vehicle.
Summary of the invention
The object of the present invention is to provide a kind of is the method for raw material liquid producing fuel ethyl alcohol by ferment with the apple residue, to reduce production costs, economizes on resources.
To achieve these goals, having technical program of the present invention lies in adopting a kind of is the method for raw material liquid producing fuel ethyl alcohol by ferment with the apple residue, may further comprise the steps:
(1) chooses raw material: choose and produce Sucus Mali pumilae apple residue afterwards;
(2) saccharification:
A, add cellulase in apple residue, every gram apple residue adds by the live amount of unit of 0.1-1 enzyme, stirs, 45 ℃ of following constant temperature saccharification 24 hours;
B, soak and filter: add the warm water of 2 times of amounts in the apple residue after saccharification, 30 ℃ were soaked 2 hours down, filtered, and obtained limpid liquid glucose, and sugar degree is 10-13%;
(3) fermentation: with the distillery yeast is bacterial classification, and inoculum size is 10%, 30 ℃ of anaerobically fermenting 5 days;
(4) distillation.
Filtration in the step (2) adopts Plate Filtration equipment to filter.
Distillery yeast in the step (3) is a Nanyang distillery yeast 1308.
Tower distillation or pillar distillation are adopted in distillation in the step (4).
Production method of the present invention is that main raw material is produced alcohol fuel with the tankage such as the apple residue of fruit product processing industry, has been to utilize the nutritive substance in the pomace to keep saccharomycetic growth with existing comparing with starchy material production alcoholic acid fermentation process; The producing and ethanol in sugared next life that has utilized Mierocrystalline cellulose in the pomace and hemicellulose components to transform to form, the productive rate that adopts method of the present invention to produce alcohol fuel is 7.22%, promptly per 100 tons of apple residues can produce 7.22 tons of ethanol (99.5%, v/v), the production efficiency height, cost is low; And adopt the method for the present invention to have expanded the raw material for fuel ethanol production scope greatly, solved pomace surrounding environment has been caused the problem of severe contamination, have good economic benefits and social benefit, help applying.
In addition, adopt every performance of the alcohol fuel of method production of the present invention to meet the GB requirement.
Embodiment
Of the present invention is the method for raw material liquid producing fuel ethyl alcohol by ferment with the apple residue, may further comprise the steps:
(1) chooses raw material: choose and produce Sucus Mali pumilae apple residue afterwards;
(2) saccharification:
A, add cellulase in apple residue, every gram apple residue is pressed the live amount of unit of 0.1-1 enzyme and is added, and stirs, 45 ℃ of following constant temperature saccharification 24 hours; (wherein, 1 enzyme live unit be every gram or every milliliter of cellulase form 1 μ mol reducing sugar at per minute conversion of substrate Xylo-Mucine (CMC-Na) amount)
B, soak and filter: add the warm water of 2 times of amounts in the apple residue after saccharification, 30 ℃ were soaked 2 hours down, adopted Plate Filtration equipment to filter, and obtained limpid liquid glucose, and sugar degree is 13%;
(3) fermentation: with Nanyang distillery yeast 1308 is bacterial classification, and inoculum size is 10%, 30 ℃ of anaerobically fermenting 5 days;
(4) adopt the distillation of tower distillation or pillar.
It should be noted last that: above embodiment is the unrestricted technical scheme of the present invention in order to explanation only, although the present invention is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the present invention, and not breaking away from any modification or partial replacement of the spirit and scope of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
