Abstract
The present invention relates to a physical and chemical treamtent method of straw and stalks, which is a processing method for raising nutrient components and volume-weight of straw and stalks and uniformly retaining all components simultaneously. Said method includes the following steps: pulverizing straw and stalks to obtain powdered material, adding additive and stirring, feeding them into briquetting machine, at the same time making physical and chemical treatment. When said mixed material is compressed and formed (i,e, physical treatment) to produce temperature, under the action of temperature the chemical treatment agent in the additive can produce chemical action on said material to implement chemical treatment to obtain block feed with high nutrients, large volume-weight and uniform distribution of all components. Said invention product is favourable for transportation and storage, and suitable for implementing industrial production.
Description
The present invention is a physical and chemical straw treating process, is a kind ofly simultaneously agricultural crop straw to be carried out physics, chemically treated processing method.The purpose of handling is to improve feeding of low value roughage such as agricultural crop straw simultaneously to be worth and unit weight, forms a kind of block crude feed product that has definite shape, keeps various uniform ingredients existence.This product nutrition height, unit weight be big, be convenient to that transportation is stored, mechanization is fed and the commercialization circulation.
The utilization rate that present agricultural crop straw is used for feed is very low, China utilize mode mainly be directly feed and ammonification after feed, directly feed and be exactly stalk without any processing or only brokenly just feed by cutting up with a hay cutter, this is a kind of ancient and traditional mode of feeding, because the stalk quality is coarse, digestibility is low, and feed intake is low, if feed stalk, its available energy inlet can't satisfy the needs of keeping of ruminant domestic animal; Feed after the ammonification is that stalk carried out the ammonification processing before feeding, processing method is to inject liquid ammonia after stalk generally is the shape stack sealing that looses, perhaps stalk sprinkling urea liquid mixes the back stack sealing, opening buttress at normal temperatures after several weeks even several months feeds, straw nutrition is worth to make moderate progress, usually can only handle in the cattle farm, feed in the in-situ processing scene; Some countries of Europe adopt basification, and because of the NaOA price is too high, the source lacks, and is not suitable for China's reality.The existing mode product that utilizes is diffusing shape, the roughage shape difference is big, and difference of specific gravity is big, bulk material in the transportation storage process because of the different different discrete phenomenas that produce of the shape of material with proportion, cause various composition uneven distributions, thereby be not suitable for the transportation storage.The principal element of more than utilizing the major defect of method also promptly to influence China's agricultural crop straw utilization is exactly that the straw nutrition composition is low, and unit weight is little and should not transport storage so that product can not batch production production, mechanization operation and commercialization circulation.The present invention makes above problem obtain system simultaneously and solves.
Physical and chemical straw treating process treatment process of the present invention is seen Figure of description one: physical and chemical straw treatment process figure, process is: with the stalk bulk material 1 after the fragmentation, admix additive 2, send into cuber 3, be processed into block roughage 4.The fragmentation here is meant pulverizing, rubs broken and cuts up with a hay cutter broken; Stalk is meant stalk class, shrub fibrid low value roughages such as corn stalk, wheat straw, millet straw, straw, herbage, pasture and water, sunflower bar, sorghum rod, reed, caragana microphylla, sea-buckthorn, branch leaf; Bulk material refers to be suitable for the stalk bulk material of ruminant or the edible granularity requirements of herbivore; Add Ji and comprise aminating agent, basifier, biochemical agent, mineral matter and trace element.Material mixes and stirs and carries and can adopt mechanization when having ready conditions.
Physical and chemical straw treating process of the present invention comprises the physical chemistry processing that stalk is carried out simultaneously.Physical treatment is meant the compression forming process of cuber to material, and its effect has three: the first is compressed bulk material, improves its unit weight, reduces transportation storage space and expense; Its two be block roughage after the compression to have one be shape, keep the various composition uniformities in the material, shape difference when transportation is stored, the different various compositions of proportion particularly mineral matter and trace element are no longer discrete; It three is for chemical treatment provides suitable temperature conditions, quickens chemical treating process.Chemical treatment is meant that chemical treatments (comprising aminating agent, basifier, biochemical agent) in the additive is to the chemical action of stalk.Purpose is to improve the nutrition of agricultural crop straw.Because the high temperature that produces during physical treatment has quickened chemical reaction velocity.Make that product reaches under the normal temperature, in the short time and the inaccessiable treatment effect of single processing.
Block crude feed product crude protein content after physical and chemical straw treating process processing of the present invention is brought up to 8-12% by original 2-5%, and digestibility is brought up to 60-65% by original 30-45%, and feeding to be worth is parity with or superiority over the northeast sheep's hay, and unit weight reaches 400-600kg/m
3This processing procedure is a kind of batch production production process, and product is convenient to transportation and is stored, can the mechanization operation, and the commercialization circulation.
Embodiment 1:
The shape crushing straw material that will loose is compressed into block roughage after admixing aminating agent and one or more other additive compositions.
Embodiment 2:
The shape crushing straw material that will loose is compressed into block roughage after admixing basifier and one or more other additive compositions.
Embodiment 3:
The shape crushing straw material that will loose is compressed into block roughage after admixing biochemical agent and one or more other additive compositions.
Embodiment 4:
The shape crushing straw material that will loose is compressed into block roughage after admixing micro-rare earth and one or more other additive compositions.
Embodiment 5:
The shape crushing straw material that will loose is compressed into block roughage after admixing mineral matter bentonite and one or more other additive compositions.
