Description
Technical field：
The invention belongs to technical field of fertilizer production, more particularly to a kind of preparation method that amino acid is extracted from chicken feather.
Background technology：
Amino acid is the organic compound that one group of molecular weight differs in size, and is the base unit of synthetic protein, amino acid
Organic nitrogen source, the amino acid of plant available molecular state can be provided.Numerous studies prove that amino acid molecular can be directly by crop
Absorb, to improve crop yield and quality, enhancing crop resistance, improve the ecological environment, thus amino acid fertilizer is as a kind of new
Type fertilizer gradually gets the nod.
Poultry feather is almost a kind of pure keratin.According to surveying and determination, the crude protein content of feather keratin is about left 91%
The right side, containing 10 kinds of amino acid such as abundant lysine, methionine, threonine, tryptophan, histidine, also contain macroelement, micro-
Secondary element, vitamin and some UGFs.Therefore, feather keratin discarded object has very by appropriate processing
Wide application prospect.At present, extract poultry feather in amino acid mainly using acid and alkali hydrolysis method, high-temperature high-pressure hydrolysis and
High pressure swelling method, and these methods not only there is highly energy-consuming, secondary pollution, production cost is high and amino acid destroys big etc. lack
Point, and the amino acid bio activity obtained is low.In recent years, by the continuous development of modern biotechnology, in the prior art
Have and prepare organic fertilizer using microbial fermentation poultry feather to extract amino acid, a kind of poultry as disclosed in CN105000923
Feather amino acid bio-organic fertilizer and preparation method thereof, it is the solution starch gemma bar by using energy efficient secretion keratinase
Bacterium, moist cellulomonas cartae and trichoderma viride fermentation enzymolysis poultry feather and edible fungi residues mixture, then in the ageing stage
Add Anti-bacterium you, dissolving phosphor and dissolving potassium bacterium carry out secondary fermentation, will be decomposed after material by crushing, sieving, poultry is prepared
Feather amino acid bio-organic fertilizer；Not only organic matter and content of humic acid are high for it, can improved soil, and amino acid content
High, species promotes crop yield and improving quality；The functional microorganism of addition can be disease-resistant, additionally it is possible to by slightly solubility in soil
Into the absorbable form utilized, the dosage of agricultural chemicals and chemical fertilizer can be reduced by being applied to production for potassium, phosphorus release, produce safety,
The agricultural product of health, have very wide application prospect.In consideration of it, applicant butchers chicken caused by laying hen chicken group using superseded
The animal matter discarded objects such as hair are primary raw material, by potassium hydroxide Hydrolyze method combination modern biotechnology, are opened by test of many times
Send a kind of preparation method that amino acid is extracted from chicken feather.
The content of the invention：
The purpose of the present invention aims to provide a kind of preparation method that amino acid is extracted from chicken feather, with reference to modern biotechnology
Means and the amino acid primary liquid of potassium hydroxide Hydrolyze method extraction, not only amino acid content is high, wherein containing abundant plant growth
Necessary nutrient, and the fertilizer efficiency containing amino acid fertilizer can be greatly enhanced.
In order to solve the above technical problems, the present invention takes following technical scheme：
A kind of preparation method that amino acid is extracted from chicken feather, comprises the following steps：
1) raw material selects：Selection laying hen, which is butchered, wants raw material based on chicken feather, and its protein content reaches 80%-85%；
2) Feedstock treating：Above-mentioned raw materials are soaked in potassium hydroxide aqueous solution, made in chicken feather containing abundant amino acid
And nutritional ingredient is hydrolyzed, amino acid primary liquid is made；
3) biofermentation：Amino acid primary liquid is added to a certain amount of biology enzyme in round, stirring makes its mixing equal
It is even, and adjust water content to 65%-80%, fermentation temperature and control at 35-55 DEG C, fermentation 7-10 days is carried out, is stirred once daily,
After the chicken feather in amino acid primary liquid is dissolved into chip, then with appropriate phosphorus acid for adjusting pH value produce amino acid fermentation in 5-8
Thing；
4) following process：The amino acid fermentation thing fermented is directly applied as amino acid fertilizer, or further to improve
Product quality and enhancing fertilizer efficiency, amino acid fermentation thing is handled after in reservoir using three-stage filtration, filled by automatic weighing
Installation enters in filling liquid fertilizer bucket, and composite microbiological fertilizer finished product is made.
Above-mentioned raw materials are soaked in 8% potassium hydroxide aqueous solution according to certain weight ratio and are hydrolyzed, and its weight ratio is
1:50。
Further, above-mentioned biology enzyme is serine protease, acid protease, bacillus protein enzyme, vegetable protein
One or more in enzyme, mold protease, Fei Shi chain enzyme bacterias, its addition are the 0.05-0.2% of amino acid primary liquid.
Further, the above-mentioned dosage for being used to adjust the phosphoric acid of pH value is the 0.5~1% of amino acid primary liquid.
Further, the above-mentioned three-stage filtration processing procedure used is successively by 300M high efficiency particulate air filters, 200M strainer
Filter and 100M laminated filters are filtered, and thoroughly remove the granule foreign in amino acid fermentation thing.
Free aminoacid content >=100g/L in the above-mentioned amino acid fermentation thing fermented, water-insoluble≤50g/L.
The beneficial effects of the present invention are：
1) present invention is butchered from laying hen and wants raw material based on chicken feather, and its raw material sources is extensive, compared with broiler breeding and other poultrys
Class excrement is dirty, and the protein content that laying hen butchers chicken feather is up to more than 80%-85%, and combining biology by potassium hydroxide Hydrolyze method sends out
Ferment, chicken feather is first hydrolyzed into the amino acid primary liquid containing potassium element and abundant nutrition composition by hydroxide ion, then pass through various lifes
The effect of thing enzyme makes other oroteins in chicken feather resolve into the amino acid that can be absorbed by plants and utilize, so that the amino obtained
The content of free amino acid is up to more than 15% in acid fermentation thing, the growth of crop is greatly facilitated, and can increase soil
Bioactivity.
2) the amino acid fermentation thing prepared by the preparation method of the present invention can be used directly as amino acid fertilizer fertilizer, also may be used
The nutrient needed for other plant growths is compounded simultaneously, composite microbiological fertilizer product is made, further increases fertilizer efficiency, is improved
The yield and quality of crop.Therefore, the composite microbiological fertilizer product prepared by the method for the present invention can be widely used for all kinds of
Cereal crops, industrial crops, gourd, fruit and vegetable etc., the innoxious synthesis of recycling is being carried out to large-scale cultivation livestock and poultry feces discarded object
While utilization, turn waste into wealth, be more beneficial for the development of green ecological agricultural.
3) preparation method technique of the invention is simple, easily operation, and environmental protection is reliable.
