Abstract
The invention relates to a production method of a feed. The production method comprises the following steps: drying crop straws, cutting the crop straws into short strips, and carrying out crushing and ball milling to form powdery materials; after carrying out wet mixing on the powdery materials by utilizing 0.3% (weight) of acid solution, putting the powdery materials into a conversion chamber, steaming and heating until the room temperature rises to 100 DEG C, and opening an exhaust gate to exhaust cool air; when the room temperature rises to a conversion temperature of 160 DEG C, maintaining the conversion for 30 minutes, then discharging conversion products, and neutralizing the discharged conversion products by utilizing the same amount of equivalent alkaline solution, so as to obtain the feed.
Description
Technical field
The present invention relates to the production method of feed, particularly crop straw is made to the method for feed.
Background technology
Crop straw often is used as animal feed by people.The total energy content of crop straw is similar to hay, but its nutritive value only be equivalent to hay half or cereal 1/4th, main cause is that its content of lignin is high, protein content is low, so digestibility and palatability are all poor: at present external adopted physics and the method for chemical treatment straw, just contact-making surface or the dissolving part lignin in order to strengthen straw and rumen microorganism, make rumen fluid be easy to infiltrate, but all fundamentally do not change the character of feed.
The purpose of this invention is to provide the processing method that a kind of stalk is processed into feed, to improve the crop straw quality of the fodder, be translated into the nourishing product of nonruminant.By stalk being processed into to the feed supply animal edible, nutriment contained in straw more effectively is converted into the products such as meat, milk by animal, and can solve the area that reduces special feed ground or meadow, improves the food production amount of unit farmland.
Summary of the invention
A kind of production method of feed, crop straw is dried, prescinds, pulverizing, the powdered material of ball milling, by powder material 0.3%(weight) acid solution mix wet after, the conversion chamber of packing into, pass into steam and heat up, room temperature rises to 100 ℃, opens exhaust brake gate discharge cold air, when room temperature rises to the conversion temperature of 160 ℃, maintain transformation time 30 minutes, then emit conversion product, with in the equivalent alkaline solution and the rear feed that obtains.
A kind of production method of feed, comprise crop straw dry, prescind, pulverizing, the powdered material of ball milling, the material water is mixed wet, after the sterilization pack, the access bacterial classification, tighten sack, in conversion chamber, with the temperature of 80 ℃, cultivates 9 days.
the specific embodiment
The institute of plant all is comprised of cell and pectic substance in a organized way, also has cured matter in protective tissue, cutin, and the gap-fill of flanking cell pectic substance, is the primary wall of each cell around pectic substance, and it is inlayed and is formed by cellulose, hemicellulose, lignin.With the propelling of plant life, in the inboard of primary wall, also can add unevenly the secondary wall that one deck is comprised of cellulose.The inboard of secondary wall is protoplast and vacuole.With the maturation of plant cell, the volume of vacuole becomes that large plasmic volume slowly diminishes and the side that is compressed in cell gradually.Protoplast and vacuole contain the nutriments such as the abundant protein that can directly be absorbed by the simple stomach animal digestion, organic acid.In cell, the cell membrane that protoplast and vacuole are formed by cellulose, hemicellulose and lignin surrounds, between cellulose and cellulose, between cellulose and hemicellulose, between cellulose and lignin matter, between lignin matter and hemicellulose, effect by chemistry and physics, turn round and connect together, form and generally be difficult to the firm barrier destroyed.
On cell membrane, single cellulosic molecule is gathered into molecular beam, forms microfibril, and microfibril is mutually assembled and formed macrofibril again, and lignin, hemicellulose are filled between microfibril, between macrofibril.Cellulose is formed by β-D-Glucose condensation, and hemicellulose is the mixture of contract sugared and pentosan more, and the pectin thing is by many contractings sugar and organic acid composition, and lignin is the condensation product of acids.The same with the monose molecule glucose that forms starch, when these polysaccharide unimolecules exist, be exactly nutriment.Usual said crude fibre, in fact comprised all compositions of plant tissue.Asking for the mesotrophic process of crude fibre, is exactly in fact to interrupt glycosidic bond, makes polysaccharide become the process of monose.
It is dry that at first the present invention shines straw (or baking), then enters cutting machine and prescind, then advance feed grinder and pulverize and wear into powder by ball mill, use 0.5%(weight) about acidic materials material is mixed wet, the conversion chamber of packing into, pass into steam.When the conversion chamber temperature rises to 100 ℃, open air bleeding valve and get rid of the cold air in conversion chamber, when temperature rises to 160 ℃, maintain and transform 30 minutes, then conversion product is emitted, then neutralize with the equivalent alkaline matter.By above processing method, smash plant tissue, separate the cell that allows mesoglea be sticky, the loose cell wall structure of folding, allow lignin, hemicellulose break away from the constraint to macrofibril, then pries open macrofibril, make it to disintegrate for microfibril, and then destroy the microfibril structure, make microfibril dissociate into single cellulosic molecule, again, reduce the aggregation degree of cellulosic molecule, make it to become low molecular state by macromolecule, last, interrupt glycosidic bond, make the cellulose of low molecular state generate glucose.Hemicellulose has generated in advance pentose in this process.
Another method of operating of the present invention is: by the powder material water after ball milling, mix wet, access bacterial classification after the sterilization pack, tighten sack, move into conversion chamber under 80 ℃, cultivated and transform with 9 day time, the bacterium be access in synthesizes the polysaccharide in material, lignin digestion, absorption processing the material of self, and finally obtaining crude protein content is 9.68%, the feed that crude fat content is 16.29%.
Embodiment 1:
Claim the 100kg straw, by its oven dry, prescind rear pulverizing, through grinding of ball grinder powdering thing, then use 30%(weight again) hydrochloric acid 0.3kg add water to 200kg and material mixed wet, will mix the wet material conversion chamber of packing into, cover tightly, pass into steam, when the conversion chamber temperature rises to 100 ℃, open drain tap and get rid of the cold air in conversion chamber.When temperature rises to 160 ℃, maintain and transform 30 minutes, then conversion product is emitted, neutralize with the NaOH0.3kg of equivalent concentration the feed that can be used as nonruminant.
Embodiment 2:
Powdery forage water is mixed to wet (humidity Wei Shou Pinch is agglomerating, the hand pine i.e. loose being advisable), pack after sterilization, the access bacterial classification, sack is tightened, moved into conversion chamber and cultivate, transforming under 80 ℃ of conditions of room temperature, with 9 day time, just can obtain containing after crude protein 9.68%, crude fat 16.29% suitable in nonruminant edible feed.
