Problems solved by technology

[0008] The first method above is to unilaterally improve the utilization rate of straw; secondly, a variety of chemical substances and trace elements are added to the raw material, the raw material composition is complex, the production process is cumbersome and slow; moreover, sealed anaerobic fermentation is mostly used, and the technical requirements are harsh. , the production is difficult, and the quality cannot be effectively guaranteed; in addition, the feed enzymes and living microorganisms are few and low in content, and the nutrient content in the straw is unbalanced, especially the protein content is too low, which limits the application of microbial degradation and fermentation technology, and the nutritional function of the product is not good. complete

Embodiment Construction

[0046] The present invention is further illustrated below by specific preparation examples. The following examples describe in detail the preferred method of the present invention for processing corn stalks, but the examples listed only illustrate the present invention, rather than limiting the scope of protection of the present invention.

[0047] The percentages involved in the present invention refer to percentages by weight.

[0048] 1. First, import 1 ton of corn stalks into the pulping reactor for chemical catalytic hydrolysis, and introduce 4Kg of concentrated sulfuric acid (concentrated hydrochloric acid, citric acid) through the guide pipe, or any mixture of any two acids or any ratio of three acids The mixture is controlled at a reaction temperature of 100°C, flashed, exhausted, back-mixed, preheated, slurried, saturated steam and mechanically stirred for 150 minutes to carry out a chemical catalytic hydrolysis reaction. In the reactor, the organic matter is hydrolyz...

Abstract

The invention relates to a method for preparing feed by rapidly hydrolyzing vegetal biomass. In the method, vegetal biomass is pre-hydrolyzed by acidification at normal pressure by utilizing bi-hydrolysis treatment technology, catalyst is added for high pressure overheating steam hydrolysis cracking, and Mailard reaction is taken in an ammonia fixing tank for fixing ammonia; the shape of water and organic matter in straw is changed in the process, and the water in straw has no phase change, so the produced material has light fragrance. The technological process of the invention can shorten production period, reduce operation cost, improve operation safety and is more beneficial to industrialized production.

Description

technical field [0001] The invention relates to a method for preparing feed, in particular to a method for preparing feed using plant biomass. Background technique [0002] my country's crop by-products-straw resources are abundant, about 700 million tons per year, of which more than 480 million tons can be collected and utilized, but only about 45% of the straw is used as animal feed, industrial raw materials and fertilizer, and the rest of the straw It is inefficiently used as a living fuel, or even discarded and burned on the spot, causing environmental pollution. On the other hand, my country's aquaculture industry is seriously short of feed materials. [0003] At present, the methods for processing straw to produce feed mainly include silage, ammoniation and biological fermentation. For silage straw feed, the stalks of the crops are taken before they are immature, at the cost of reducing or sacrificing the grain output, and it is difficult to form an industrialized prod...
