Abstract
The invention discloses a preparation method of crop straw feed for Hu-sheep feeding. The preparation method comprises the following steps that firstly, crop straw is simply smashed and ground; secondly, the ground crop straw is subjected to chemical treatment, therefore, the straw is softened, the microstructure is improved, and the blasting effect is conveniently improved; thirdly, the treated straw is subjected to steam explosion treatment; finally, water washing and drying are conducted, and then the crop straw feed is obtained. According to the method, the total sugar content of the straw can be significantly increased, and the degradation rate of cellulose and hemicellulose is increased; meanwhile, after the crop straw is treated through both chemical treatment and the stream explosion technology, not only is the nutritional value increased, but also eggs, mould and viruses in the straw can be killed, and therefore the crop straw is quite suitable as the feeding feed of Hu-sheep.
Description
Technical field
The present invention relates to the preparation method of a kind of animal feed, be specifically related to one and feed as sheep
The preparation method of the crops straw stalk feed supported.
Background technology
China is a large agricultural country, and crop specie enriches, and mainly includes cereal crops warp
Ji crop (oil crop, vegetable crop, flowers and plants, fruit and hobby crop etc.), industry
Crop, forage crop, medical material etc..According to the generally understanding of current people, so-called agriculture
Crop material is the general name of ripe crops stem and leaf (fringe) part, it is common that refer to that crops are being received
Obtaining the remainder after seed, its average product is typically about more than 1 to 2 times of seed.According to
This, the agricultural crop straw of broad sense refers to the various plants agriculturally cultivated remaining after results seed
Remaining part is divided, and the agricultural crop straw of relative narrow sense is primarily referred to as cereal crops, industrial crops and work
Industry crop remainder after results seed and the whole plant of forage crop whole.
Agricultural crop straw is a kind of Organic substance, and wherein carbon, oxygen, three kinds of chemical composition summations of hydrogen account for 95%
Above, remaining is the mineral elements such as potassium, nitrogen, phosphorus, silicon, calcium, magnesium, sulfur, but content is relatively
Low；Organic principle based on cellulose, hemicellulose, secondly be lignin, protein,
Fat, ash.Cellulose in agricultural crop straw, hemicellulose are combined closely with lignin, phase
It is wound around mutually and constitutes crude fibre, be the main component of plant cell wall.
Agricultural crop straw is produced in the whole production process of animal feeding-stuff can be effectively improved fermentation
The key link that product nutrient is worth is: pretreatment, the degraded of cellulose, white microorganism of laying eggs
Application and the control of sweat conditional to saccharide.For pretreatment, the most in practice
Be difficult to find effective, be easy to a large amount of production practices method that cost is the lowest simultaneously；For process
Middle cellulose and hemicellulose, on the one hand its degraded is affected by pretreating effect, another
Aspect is affected by microorganism itself and fermentation.At present about in agricultural crop straw
The degradation effect of cellulose and hemicellulose is the most undesirable, further limit agricultural crop straw and makees
Application for domestic animal, especially feedstuff for hu yang.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of crops fed as sheep
The preparation method of straw feed.
The present invention can be achieved through the following technical solutions:
The preparation method of a kind of crops straw stalk feed fed as sheep, including following step
Rapid:
(1) crops stalk crushing after air-drying, grinds, and grind size is 100 mesh；
(2) agricultural crop straw after grinding under room temperature is immersed in the acetic acid that concentration is 0.1%
In solution, add nanoscale solids acid catalyst, after stirring, soak under enclosed environment
Bubble 3-5h, wherein agricultural crop straw: acetic acid: the weight ratio of solid acid catalyst is 1:8:2；
Described solid acid catalyst includes SO4 2-/Fe2O3、SiO2-Al2O3, molecular sieve catalyst,
One or more in Kaolin and cationic resin；
(3) agricultural crop straw after soaking in step 2 loads in steam-explosion jar, then adds dense
Degree is the ammonia of 5%-15% and the mixed solution of the hydrogen peroxide of 10%, after stirring, continues
Continue and be passed through saturated vapor, after making steam explosion pressure inside the tank be 1.5MPa, open steam explosion button and carry out
Steam explosion, and hold time as 8min；Described straw is 1:1 with the weight ratio of mixed solution,
The weight ratio of ammonia and hydrogen peroxide is 3:1；
(4), after steam explosion terminates, the spherical of the receptor top that is connected with steam-explosion jar is quickly opened
Valve, carries out moment pressure release, after the agricultural crop straw that sudden strain of a muscle is produced enters receptor by pressure reduction, then
Clean with tap water, obtain crops straw stalk feed after drying.
What the present invention obtained has the beneficial effect that 1) its preparation process of the present invention is simple to operate,
Cost is relatively low；2) steam explosion technology is applied the preparation field at animal feeding-stuff, consume energy relatively low,
The suitability is strong, and batch production is easy in the application of this technology, reduces production cost；3)
Adding ammonia and hydrogenperoxide steam generator in steam-explosion jar, the total sugar that can dramatically increase straw contains
Amount, improves the degradation rate of cellulose and hemicellulose；4) in chemical treatment stage, add
Solid acid catalyst can be catalyzed straw at short notice and hydrolyze, agricultural crop straw warp simultaneously
Cross chemical treatment and after steam explosion technology is jointly processed by, not only increase nutritive value, moreover it is possible to kill
Worm's ovum, mycete and virus in straw, is highly suitable as the feed for nursing of sheep.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further illustrated.
Embodiment
The preparation method of a kind of crops straw stalk feed fed as sheep, including following step
Rapid: (1) will air-dry after crops stalk crushing, grind, grind size is 100 mesh；(2)
It is 0.1% that agricultural crop straw after being ground by 1 weight portion under room temperature is immersed in 8 weight portion concentration
Acetic acid solution in, add 2 weight portion nanoscale solids acid catalyst SO4 2-/Fe2O3, stir
After mixing uniformly, under enclosed environment, soak 5h；(3) after 1 weight portion step 2 being soaked
Agricultural crop straw load in steam-explosion jar, then to add the concentration that concentration is 0.75 weight portion be 15%
Ammonia and the mixed solution of the hydrogen peroxide that concentration is 10% of 0.25 weight portion, stirring is all
After even, continue to be passed through saturated vapor, after making steam explosion pressure inside the tank be 1.5MPa, open steam explosion
Button carries out steam explosion, and holds time as 8min；(4) after steam explosion terminates, quickly open with
The globe valve on the receptor top that steam-explosion jar is connected, carries out moment pressure release, dodges the crops produced
After straw enters receptor by pressure reduction, then clean with tap water, obtain crops straw after drying
Stalk feed.
The total sugar content of straw can be dramatically increased by the inventive method, improve cellulose and
The degradation rate of hemicellulose, agricultural crop straw is through chemical treatment and steam explosion technology common point simultaneously
After reason, not only increase nutritive value, moreover it is possible to kill the worm's ovum in straw, mycete and virus,
It is highly suitable as the feed for nursing of sheep.
