Production line and preparation method for straw fiber biological feed

Abstract

The invention discloses a production line and preparation method for straw fiber biological feed, relates to the technical field of straw feed equipment. The production line solves the problem duringstraw softening, the problem during straw fiber preparing, the problems that palatability is poor and the digestion and utilization rate is low due to the fact that straw fiber is mixed with a nitrogen source and nutrients insufficiently and unevenly and industrialized production cannot be realized, and the problem of how to produce high-quality straw by the preparation method of the production line and how to improve the market competitiveness. The production line consists of a straw feeding and conveying device, a straw spiral drive feed horizontal constant steamer, a straw fiber grinder, anitrogen source and nutrient metering and mixing device, a drying machine, a straw fiber and nutrient steam explosion mixing device and a baler. The production line employs a programmable logic controller (PLC) full-automatic control system, and has the advantages that the design is skillful, the process is stable, production capacity is high by straw consumption, the production efficiency is high, and large-scale industrialized production can be realized.

Description

technical field [0001] The invention relates to the technical field of straw feed equipment, in particular to a production line of straw fiber biological feed and a preparation method thereof. Background technique [0002] my country is a large agricultural country with an annual output of more than 600 million tons of crop straw. At the turn of autumn and winter, the burning of corn straw pollutes the air and often causes a lot of smog. How to develop and utilize straw is one of the major issues in contemporary agricultural development. In this regard, in recent years, the state has organized relevant departments and forces such as production, academia, and research to conduct useful explorations for many years, using physical, chemical, and microbial methods to improve the utilization rate of straw, but in general, there is no Fundamentally changing the situation, there are still various problems, such as high cost, not economically cost-effective, difficult, technically ...

Problems solved by technology

[0003] The invention aims at the problem that the existing straw feed cannot solve the problem that the straw is hard and affects the digestion of ruminants, especially for the problem of producing high-quality fiber feed due to the single method of steam explosion and microbial technology, which cannot better destroy the waxy layer of the straw, and the production Due to the limitations of complex procedures and increased costs, through the production line, it is necessary to solve the problem of softening and grinding the straw into fibers and destroying the waxy layer of the outer layer of the straw, and solve the problem of melting and cracking of the lignin between straw fiber cells and between layers of cells , solve the problem of precise measurement of nitrogen source nutrients, solve the problem of thinning lignin and soft texture of straw through steam explosion technology, solve the problem of poor palatability and digestion caused by insufficient and uneven mixing of nitrogen source nutrients and microbial agents for straw feed The problem of low utilization rate and inability to industrialized production; the existing method can not improve the physical structure of straw fiber, the growth of physiologically beneficial microbial flora in livestock such as cattle and sheep and the ability to resist disease immunity are poor, and the The palatability and nutritional value of the feed are not high, the digestibility of ruminants to crop straw feed is poor, the speed of weight gain of cattle and sheep and other livestock is accelerated, and the cost of feed production and market competitiveness are effectively reduced. A straw fiber biological feed is provided. production line and preparation method thereof, the technical scheme to solve the problem is as follows:
