The briquetting feed industry is an emerging industry in China. It is born in response to the great environmental development that China strongly advocates for sustainable development. Its emergence has a certain role in promoting the adjustment of agricultural industrial structure.
China is a large agricultural country with an annual output of more than 600 million tons of crop straw. These straw resources can be a good feed for a large number of herbivorous livestock such as cattle and sheep if they are effectively processed. However, in the past, due to the relative lag of processing and utilization methods, a large number of straws were burned or weathered, mildewed, wasted resources, polluted the environment, and became a public nuisance. The production of forage/straw briquetting feed technology has effectively solved this problem.
First, the advantages of pasture / straw briquetting feed:
1. Seasonal forage can be processed into a storable four season forage.
In spring and winter, there is a shortage of forage grass and crop stalks, and there are few nutrients, and the animals are generally short of grass. In summer and autumn, various crop stalks and pasture resources are extremely abundant, but they cannot be effectively utilized. Therefore, it is the best way to solve this contradiction by mechanically processing these straw and forage resources into a briquette feed, making it a four-season feed that can be stored for a long time.
2, can achieve the conversion of pasture / straw.
The distribution of straw and pasture resources in China is uneven, the resources in the north and west are abundant, while the resources in the east and south are scarce. The stocks of livestock in the east and the south are increasing every year, and the grass shortage is serious. The briquetting feed technology can heat the common pasture/straw. Compression, the density is 15-20 times that of the original, making it a commodity that can be transported over long distances, making it possible to achieve off-site conversion.
3. It can effectively solve the current situation of "human and animal competition for food" in China.
At present, China's grain and pasture production is insufficient, and the situation of "human and livestock competition for food" has been formed. Feed has become the main bottleneck restricting the development of animal husbandry. How to develop and utilize more than 600 million tons of crop straw resources will accelerate the development of animal husbandry and solve cattle 3. The main way for the contradiction of high quality forage for grass and livestock. The research and development of efficient and reasonable processing and utilization technology of straw resources will be an important technical support for realizing the utilization of straw feed resources, industrialization and large-scale utilization.
4, can increase the palatability and feeding rate of ordinary straw, and enhance the feeding effect.
After the ordinary straw is processed by mechanized briquetting, the palatability of the raw and cooked food is improved, the feeding rate is 100%, easy to digest and absorb; the feeding is convenient, and the mechanized feeding is convenient; the nutritional level is improved.
Second, pasture / straw briquetting feed processing technology:
The processing equipment of the briquetting feed is a forage/straw compression complete equipment, and the equipment consists of a cutting system and a feeding system. The mixing system, compression system and output system are composed of five systems. The production process of the briquetting feed is as follows:
1. After the straw straw raw materials are air-dried and dried, the cutting system is cut by the cutting system, and the length of the cutting is 3-5cm:
2, after the cutting, stir and stack, so that the humidity is even, the moisture is controlled at 20%;
3. Feeding through the conveying system. The feeding requirements are kept uniform and the impurities in the raw materials are removed as much as possible.
4. The raw material enters the agitation system for agitation. The de-ironing device in this system can effectively remove the metal substances in the raw materials.
5. After the agitation, the raw materials enter the compression system for friction extrusion, and the finished product is regularly extruded through the module. The maximum temperature of the outlet can reach more than 100 degrees, and the raw materials are matured.
6. The finished product is output through the cooling output system. After drying/k parts, the general moisture content is below 14%, and the weighing package can be stored and transported.
The specifications of the briquettes feed are generally 30 mm x 30 mm or 32 mm x 32 mm in cross section and 20-80 mm in length.
The briquetting feed is suitable for a wide range of raw materials: alfalfa, leymus, sand-sand, corn stover (core), cottonseed, straw, rapeseed, bean straw, peanut meal (shell), sweet potato, etc. can be processed into roughage; wheat straw, cotton Straw can be processed into industrial raw materials.
Third, the pressure block feeding effect analysis:
After the high temperature compression of crop straw, the palatability, feeding rate and nutritional level were improved.
