Abstract
The present invention relates to a cracking agent for plant coarse fibers and a method for treating plant coarse fibers by using the cracking agent for coarse plate fibers. Certain amounts of hydrogen peroxide, alkali and/or water-soluble carbonate and hypochlorite are mixed to form the cracking agent for coarse plant fibers; the cracking agent for coarse plant fibers is added to a coarse plant fiber material with the water content of 10 to 15%, so that the coarse plant fiber material is (chemically) cracked under the hermetic condition for 2 to 7 days and then cracked again at 150 to 300DEG C so as to obtain the cracking agent. Compared with the prior art, the present invention is suitable for various plant fiber materials and has the advantages of high cracking efficiency and low cost.
Description
The present invention relates to a kind of composition of energy cracking plant crude fiber and utilize it vegetable material to be become the method for animal feed or other foodstuff.
Plant crude fiber mainly is meant discarded object (as straw, tangerine bar, wheat husk, corncob etc.) and processing byproduct (as rice husk, system chaff, wheat bran, bean dregs, bagasse etc.) and other plant in the crops production.Except that directly utilizing fiber (as papermaking etc.), because the basic composition unit of plant crude fiber is a glucosyl group, so the plant crude fiber through cracking is widely used as feed, fermentation, food, building, oil, papermaking, the raw material of chemical industry and Edible Fungi, the cleavage method of plant crude fiber has also just become the problem of people's extensive concerns, hydrolysis, enzymolysis, fungi degradation, softening, expanded, methods such as ultramicro grinding are arisen at the historic moment, but these methods are low to the cracking ability of plant crude fiber, and investment is big, complex process, the crude fibre availability is low, the also generation environmental pollution that has.Chinese patent CN1149411A discloses a kind of puffing aid of inventor's invention and has utilized it to handle the method for rice husk and system chaff, it is carbonate to be refueled the puffing aid that lipid grouts and suitable quantity of water be made into add the plant crude fiber raw material, carry out expanding treatment after the mixing, can make the crude fibre of rice husk or system chaff obtain cracking, but the treatable material variety of this method few (only being used for rice husk or system chaff), because pure broken physics cracking, cleavage rate is still not high, expanded energy consumption is high and cause the product cost height under high-temperature and high-pressure conditions, and economic benefit is not high.
The objective of the invention is at the treatable material variety of prior art scheme few, the cost height, lytic effect is bad, the shortcoming that economic benefit is not high, provide a kind of cost low, lytic effect is good, and can handle splitting agent for coarse plant fiber and other using method of various materials.
Technical scheme of the present invention is:
A kind of splitting agent for coarse plant fiber, the parts by weight of its composition and each component are:
A), hydrogen peroxide 10-30,
B), bases and/or water soluble carbonate 1-3,
C), hypochlorite 0.5-3.
In the above-mentioned composition, hydrogen peroxide should be adjusted to and contain H
2O
230% standard; Bases can be NaOH, potassium hydroxide, ammonium hydroxide, calcium hydroxide etc.; Water soluble carbonate can be sodium carbonate, sodium acid carbonate, carbonic hydroammonium etc.; Hypochlorite can be clorox, hypochlorous acid ammonium, calcium hypochlorite etc.
The using method of this splitting agent for coarse plant fiber is: the 10-35% of the gross weight of the plant crude fiber of handling by desire determines the component and the parts by weight of decomposition agent, each component taken by weighing to mix by weight add through preliminary treatment (chopping or pulverize, water content 10-15%) plant crude fiber raw material is (as straw, straw, rice husk, the system chaff, wheat husk, wheat bran, corncob, bean dregs, bagasse etc.) in, mixing was placed in the closed container just cracking 2-7 days, again 150-300 ℃ of condition (as warm ejector, fluid bed dryer, bulking machine, during pneumatic conveying drying bed etc. is provided with) under carry out continuous industryization again cracking promptly get product.
The present invention greatly strengthens the coarse-fibred ability of its cracking owing to added hydrogen peroxide and the hypochlorite with strong oxidation in decomposition agent, and the comparable existing method of lysis efficiency improves 30-50%, all can be suitable for various plant crude fibers; After separating, airtight chemical incipient crack use the physical method cracking just easier again, having overcome former technical scheme only depends on the electric energy effect to form high-temperature high-pressure swelling and the high deficiency of energy consumption height, cost that causes, through using proof, the comparable former method 70-80% that reduces cost can reach goal of the invention fully.
