Description
Technical field
The present invention relates to feed processing technology field, the method being specifically related to a kind of cottonseed meal processing feedstuff.
Background technology
China is a Ge Chanmian big country, has an abundant cotton resource, produces Semen Gossypii amount per year up to nearly ten million ton,
Except sub-fraction gives over to kind of a use, remaining for extracting oil, the cottonseed meal produced every year reaches millions of tons.
Wherein the cottonseed meal for feedstuff only accounts for about 15%, and remaining is mostly as Fertilizer application.In cotton cake dregs
Protein content account for 30%-45%, suitable with bean cake, protein content exceeds rice and Semen Tritici aestivi 5-8 times.
Cottonseed meal contains 17 kinds of aminoacid, and wherein lysine content is relatively low, is 1.48%, and arginine content is high,
Reaching 3.6%-3.8%, the ratio of lysine and arginine is considerably beyond the ideal value of 100:120.Vitamin and
Mineral aspect, cotton cake dregs is rich in thiamine in vitamin B complex, and phosphorus content is more than 1.0%, and calcium is the lowest
In 0.03%.
Restriction cottonseed meal is to cry cotton containing one in cottonseed meal as a main cause of feed applications at present
The toxin of phenol (Gossypol), accounts for the 0.7%-4.8% of Semen Gossypii, and gossypol is Malvaceae cotton pigment gland
Polyphenol two naphthalene derivatives produced.Gossypol is a kind of ginger-colored crystal, and fusing point 181-185 DEG C, is that one is many
Unit's compound, has multiple isomer.Gossypol has free state and combined state two kinds, and " bound gossoypol " is
Gossypol is during high temperature steams and fries, and albumen, saccharide in free gossypol and Cottonseed are bound up, it
Not absorbed in digestive system, can quickly excrete with feces, toxicity is the lowest；" free gossypol " is
Active aldehyde radical and the gossypol of activity hydroxy, its toxicity is relatively big, and content exceedes margin of safety, will cause
Growth of animals or poultry is slow, poisoning, breeding potential decline and death.Additionally, containing activity aldehyde radical and activity hydroxy
The phenolic group of free gossypol or phenolic group oxidation product quinonyl can be with the active groups of protein amino acid residues in feedstuff
Group's (such as epsilon-amino, sulfydryl of cysteine of lysine) combines and generates insoluble complex, and also
Can be combined with the proteolytic enzyme in digestive tract, suppress its activity, thus reduce the utilization of protein
Rate.Free gossypol has stimulation to gastrointestinal mucosa, causes gastrointestinal mucosa inflammation and hemorrhage, and can increase
The permeability of blood vessel wall, makes hemocyte and infiltration of plasma to peripheral tissues, causes tissue generation blood plasma of being injured
Infiltration.It also can be combined with protein and ferrum, the effect of ferrum in infringement hemoglobin, causes lacking of poultry
Ferrum anemia.Gossypol makes body severe potassium deficiency, can cause Hypokalemia paralysis disease, liver, nephrocyte and blood vessel god
Through impaired, neural activity is suppressed, sudden cardiac arrest or respiratory paralysis.After free gossypol is dissolved in phospholipid,
Neurocyte accumulates, causes the function of neurocyte to get muddled.
At present, in feedstuff, the biodegrading process of free gossypol mainly has: Physical and chemical method, but this two
The method of kind is respectively provided with the problem that workload is big, process conditions are harsh, gossypol degradation rate is low.
Summary of the invention
The technical problem to be solved is to provide a kind of edible safety, nutritious cottonseed meal
The method of processing feedstuff.
The technical problem to be solved realizes by the following technical solutions:
A kind of method of cottonseed meal processing feedstuff, concrete processing method is as follows:
(1) cottonseed meal after oil expression is put into immersion 6-12 hour in clear water, then take out feeding pressure filter
Filter pressing, retains cottonseed meal filter cake stand-by；
(2) cottonseed meal filter cake is pulverized, cross 60-80 eye mesh screen, be placed in low-temperature cold wind drying machine, in
55 DEG C-60 DEG C keep 30-40 minute；Low-temperature cold wind is used to be dried the effective nutrition one-tenth that can retain cottonseed meal
Point, high temperature is easily destroyed the active component of cottonseed meal；
(3) sending in blender by the cottonseed meal powder after cold air drying, in blender, addition accounts for low simultaneously
Temperature cold air drying after the zymocyte liquid of cottonseed meal grain weight amount 0.5-1%, the Cortex Dictamni extract of 0.2%, 0.5%
Sal, the zinc sulfate of 0.02%, the Chinese liquor of 0.6% and the corn peptide of 0.05%, stir continuously in blender
Mix mixing more than 50 minutes；
(4) the cottonseed meal powder after stirring is stood 2-3 days in the warehouse of 25-28 DEG C, cottonseed meal powder is entered
Row fermentation process, reaches preliminary detoxification purpose；
(5) the cottonseed meal powder after fermentation is pulverized, crosses 80-100 mesh sieve, prepare cottonseed meal powder,
Putting in nylon ball grinder by cottonseed meal powder again, with agate ball as abrading-ball, ball material mass ratio is 5:2,
Under conditions of rotating speed is 140 revs/min, continuous ball milling 2 hours；The fiber group of cottonseed meal is broken up by ball milling
Knit, accelerate the precipitation of gossypol in cottonseed meal；
(6) putting in reactor by the cottonseed meal powder after ball milling, dilute, the addition of water is cotton
1.5-3 times of seed dregs of rice powder weight, injects steam while stirring, makes the steam temperature in reactor reach
110 DEG C-130 DEG C, it is sufficiently stirred for, makes cottonseed meal slurry be heated evenly, by steam heat treated, make thing
Cortex Dictamni extract, zinc sulfate, Chinese liquor and corn peptide in material are filled with free gossypol under the infiltration of steam
Divide reaction and complexation, when tank pressure rises to 0.09MPa, keep 5-20 minute, after tank pressure is down to zero, take
Go out the cottonseed meal slurry after detoxification；
(7) the cottonseed meal slurry after detoxification is sent into pressure filter filter pressing, then filter cake is pulverized dried and get final product
Cottonseed meal feedstuff.
The invention has the beneficial effects as follows: present invention process is relatively simple, equipment investment is few, easy to operate,
Detoxification efficiency is high, the good palatability of the virus-free cottonseed meal feed prepared, and digestibility is high, and antinutritional factor
Content low.
