Straw feed briquetting process

Abstract

The invention discloses a straw feed briquetting process. The straw feed briquetting process comprises the following steps: S1, straw harvesting: selecting harvested high-quality straw, and removing withered and rotten parts in the straw; S2, straw cutting: cutting the straw into equal-length or short straw sections for subsequent use through a cutting machine; and S3, straw scattering: adding thecut equal-length or short straw sections into a rolling machine for rubbing so as to destroy thick and hard skin and hard stem knots of the straw and rub the straw into a filamentous structure. According to the invention, the straw is rubbed into the filamentous structure, and then rapid low-temperature freezing and dehydration in a vacuum state are performed; compared with natural drying, nutrient substances in the straw and the green color of the straw can be effectively reserved, the taste and the color of the straw are enhanced, and the straw is highly attractive to livestock; and the straw is convenient to store and transport after microbial anaerobic fermentation, digestion and absorption by livestock, compression into blocks, sealing and packaging.

Description

technical field [0001] The invention relates to the technical field of straw feed, in particular to a briquetting process of straw feed. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after the seeds are harvested. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource, and straw is also a roughage. [0003] Straw can be supplied to livestock as feed after bundling and briquetting, which not only saves straw from burning and reduces pollution, but also recycles straw and reduces animal husbandry costs. After the straw is harvested, the straw is dehydrated by 50%-60% under natural light conditions, and then bundled or brique...

Problems solved by technology

[0003] Straw can be supplied to livestock as feed after bundling and briquetting, which not only saves straw from burning and reduces pollution, but also recycles straw and reduces animal husbandry costs. After the straw is harvested, the straw is dehydrated by 50%-60% under natural light conditions, and then bundled or briquetting, but the time is longer, and the color of the straw will gradually turn yellow, and the nutrients in the straw will fade with time. increase and loss
