12 defects analysis and countermeasures affecting the quality of pensions

LIMA Fish Feed Machine,Chicken Feed Machine

The puffed aquatic feed is a new aquatic product that is gradually accepted and promoted by the majority of farmers with a low pollution, low waste, high efficiency and high conversion of feed. In recent years, my country’s aquatic feed production has grown rapidly, and the development of shrimp and precious special aquatic products is very fast. In th special aquatic feed, extruded puffed particulate feed has become the main product form. Since the extruded puffed aquatic feed production line is more new, especially the control technology of the operating conditions of the extruded duffling machine is not perfect, many do tic feed manufacturers on the processing technology and production characteristics of the puffed aquatic product feed is still in the continuous exploration. And the stage of development, the quality of the feed products produced by each manufacturer will have a large difference. Even with the same manufacturer’s quality of the same variety products in different batch products, there may be greater fluctuations. Unable to ensure the stability of physical properties. After years of production practices.
It is considered that the following defects generally occur in the processing of extruded materials: 1) Uneven particle size and length; 2) Particle pores; 3) Particle deformation; 4) Particle hardness is not enough; 5) Particle water resistance is not good, viscoelasticity Poor; 6) The incisions of the particles are not neat and oblique; 7) The swelling of the particles is not high; 8) The particles are submerged in water; 9) The particles are large at one end and small at the other; Tail; 12) Peeling of the surface of the particles. After years of practical experience in production, the author summarizes some problems that often occur in the processing of puffed materials, and proposes corresponding solutions. 1. Uneven particle size and length Uneven size and length of feed particles will not only affect the appearance of the feed, but also affect its palatability and water resistance time inconsistency, resulting in unnecessary waste. In addition, it will also become an excuse of a farmer complaint. 2. Particle pores the particles are more pore, but the outer surface is not only affecting the appearance of the feed, but the feed is easily broken in the transportation process, causing unnecessary waste. It is not easy to sink during feed feed, and the floating time is long. Service Livestock 3, Particle Deformation Not Circle Particles Deformation, may be due to mold hole Deformation, or due to excessive moisture, extruding deformation during transportation during the mold. Therefore, the high-temperature puffed feed for the just drawn is preferably used, so that the surface of the particles can be quickly formed of a layer of colloidal wrap, not only the fragmentation of the particles, but also the shape of the granules can be rounded. However, the moisture of the particles during the gas transportation is very heavy, and it needs to be dried as soon as possible. The particle deformation is not far, causing the particle size uneven, affecting its right level. Service Livestock 4, Particle Hardness is Not Hardness is Deformation Resistance. The feed hardness is not enough, which will cause the feed to deform in the handling, which affects the appearance of the feed. It may cause the feed to dissolve in the water before being fed, or it may be that the moisture is large, and the feed is not easy to store, and it is easy to produce mildew. 5, Particles Water Water Resistance Sexually refers to the anti-solubility capacity of the feed in water, which is usually expressed in the amount of loss rate of feed in water under the predetermined conditions. The poor feed resistance of feed can result in dissolution in water before being fed, causing unnecessary waste, and pollutes water quality. Natural viscoelasticity, resulting in poor goodness of feed. 6, Particle Insulation Not Neglings, Junjun Serving the Feed Production of Livestock Production A neat particles, unregulated, deformed particles affect the appearance of the feed. It is generally caused by unreasonable adjustment of the incision and cutter, and may be due to the fact that the amount of charge is too large. 7, Granular Prestige Rate Not High , Solulent Time Long, affect its right level and digestibility. The high content of the lipid compound will reduce expansion, when the fat content is 17 to 22%, the product is influentially or non-influential. The particle pensive rate will result in a short time to float in the water, which is easy to sink into the bottom of the water, causing unnecessary waste.. 8, Granules have Shenshui Phenomenon Granules have a water phenomenon, It is the reason why the puff coefficient is too low, the material is too heavy. Some particle floating materials If there is a water phenomenon, one is to cause unnecessary waste, and the other is that it is difficult to observe the fish to eat. 9, Particles A big – Granules A big small, Impact feed is beautiful, it is easy to cause feed fracture, and the powder rate is improved, and the preparation is lowered. 10, Particle Forming Double Swipe Double Concave Particle Double Sidap Shape, the amount of feed is uneven, the proportion of water and steam is unreasonable, and this is usually the case. Unregulated particles, not only affect the appearance of the feed, but also cause more feed powder, affecting its right level. 11, Particle Tail Particles Tail, Many Reasons Mainly a problem of cutters. Feed particles with tail, but not only affect the appearance of feed, will also lead to more feed powder. 12, Particle Surface Test Surface Deleting Early During Transportation Process Producing dust, surface peeling may be lacking in water, and it is also possible to be affected by molds and cutters in processing processes. It not only affects the beauty of the appearance of the feed, but also causes more feed powder. The moisture is added, and the formed material is too soft, easy to deform, generally should be divided into water at 25 to 30%. Surplising can also affect the water resistance of the feed. The quality of the product is doubtful to the quality of the product.
