Feed processing device

Abstract

The invention provides a feed processing device, and relates to the field of feed processing. The feed processing device comprises a conveying pipe, a motor a, a motor b, a feeding hopper, a water tank, an extrusion pipe, a pressing mechanism and a supporting frame, a feeding groove is formed in the outer wall of the top end of the conveying pipe, the inner wall of the feeding groove is welded to the feeding hopper, the motor a is arranged on the outer wall of one end of the conveying pipe, an output shaft of the motor a is connected with a spiral auger a through a coupling, the outer wall of the bottom end of the conveying pipe is fixedly connected with the supporting frame through screws, the outer wall of one side of the supporting frame is movably connected with the water tank, and the extrusion pipe is welded to the conveying pipe. According to the feed processing device, cracks on the surfaces of particles caused by different humidity during straw pressing are prevented, feed can be rapidly cooled during extrusion forming, the Maillard reaction during feed pressing is slowed down, the formed feed is flatter and smoother and is not prone to being excessively wet or fragmentary, and meanwhile spraying of straw powder is reduced.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a feed processing device. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds. 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. It is characterized by high crude fiber content (30%-40%), and contains lignin and so on. Although lignocellulose cannot be utilized by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock. The feed pellets processed by the feed pellet machine have a certain hardness, and the chewing time o...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a feed processing device, which solves the problem of adding other nutrients to wheat straw in feed processing to make feed, which can not only avoid straw burning and pollute the environment, but also improve the economic benefits of agriculture. In the large-scale straw press machine, due to the different seasons and different weathers of the straw, the water content of the straw is different, it is difficult to judge and control, it will affect the production quality of the pressed feed, there will be cracks on the surface of the pellets, and even the finished pellets cannot be produced. , granulated, but there are many problems such as powder coming out, lysine from protein or added crystals and reducing sugar can combine under appropriate humid and hot conditions to form indigestible components, which will also reduce the animal's feed absorption efficiency The problem
