Cleaning of feed raw materials

LIMA Fish Feed Machine,Chicken Feed Machine

I. The purpose of cleaning and requires serving livestock in raw materials entering the feed mill, can be divided into vegetable raw materials, animal raw materials, mineral materials and other small varieties of additives. Among them, animal raw materials (such as fish powder, meat powder), mineral raw materials (such as stone powder, calcium hydrogen phosphate), and vitamins, drugs, etc. have been completed during raw material production, generally no longer cleaned. The feed mill is mainly cleaned to be a cereal raw material and its processing by-products. Cleaning of liquid raw materials such as molasses, grease, etc., is placed on the pipe and the like for cleaning. the service livestock feed cereals often mix some sandy, dandruff, straw and other impurities. The prnce of a small amount of impurities has great effect on the quality of the feed finished product. Since the finished feed is widely limited, the feed raw material is cleaned, not exactly not to ensure the content of the finished product, but to ensure the safety production of the processing equipment, reduce equipment losses, and improve processing. health. Processing Factory has two types: Screening method: Slims larger than and less than the feed, Big impurities and small impurities such as straw. Service Animal Magnetic Selection: To partially divide various magnetic impurities. Service Animal Husband In addition, in screening and other processing processes, it is common to drain dust to improve the environmental hygiene in the workshop. , Screening 1. Sliding Structure Service Animal Science Screening is based on materials One operation of the particle size size of the impurities is performed. The material smaller than the screen is smaller than the sieve is a pure material (sieve), which is larger than the impurities of the sieve cannot be cleaned out by the screen hole (sieve), both or the opposite. Subligers commonly used in feed mills include cylindrical (or conical) primary cleaning sieves, powder primary cleaning and planar swing grading sieve. (1) Raster Sieve, the grid sieve at the vote (below) is the first line of defense of the raw material, the main role is the initial cleaning of the raw materials Protective sequencing equipment and workers’ safety. The gap of the grid is determined according to the geometric size of the material. The grain raw material such as corn should be about 30mm, and the oil cake should be around 40 mm. At the same time, the grid sieve has a certain strength, typically welded with a thick 3 mm, a width 2 cm of flat steel or §æ10 mm round steel. It should be fixed to the mouth (lower) mouth, and ensure that there are 8 ~ 10 degs; the inclination is allowed to pour the material in the bag, reduce the labor intensity of workers. the grid sieve of the unloading is made from thick 4 mm, width 5 cm steel sheet. (2The punched screen, punched screen, also known as the screen, is usually made of a thin steel plate (black iron) or galvanized iron plate (white iron). The shape of the screen is circular, rounded, and triangular, as shown in Figure 3-7. The thickness of the screen is generally dependent on the size of the screen, and the sieve surface of the sieve is thinner, the sieve surface of the sieve hole or the severe wear is appropriately thickened to enable the screen surface to have sufficient strength. Over-thick screen, the screen is easy to block when the screen is used, and the strength is not enough, and the thickness of the general sifter is 0.5 to 1.5 mm. (3) Weng Screen, the woven screen can be woven by wire (such as steel wire, galvanized wire, etc.), chemically synthesized wire. The sieve of the knitted screen has a rectangle, square in square. The thickness of the wire used by the woven screen surface is determined according to the size of the screen, and the general diameter is between 0.5 to 1.5 mm, the powder and pellets can be used. 2. Screening Principles A t Sie Machinery Clear the impurities in the feed, and grade feed. The sutation is the difference in particle shape, width, thickness, etc. according to the material particles, so that they become a sieve by the screen surface, and the other portion is left on the screen, thereby separating the feed and impurities, reaching removal. The purpose of impurities, or feed separate from different sizes and different shapes to perform grading treatment. with a circular hole screen or a square surface, which can be separated from the particle width. The width of the feed particles or impurities is smaller than the sieve diameter. When sliding on the screen surface, the particles are established when the particles are small in the hole, and the top end is set to the hole, which is a sieve, beco a sieve, the width is greater than the diameter of the screen Materials become sieves. The long hole sieve can be separated differently according to the thickness of the particles. When the thickness is less than the thickness of the sieve, when the screen is slid, the inclinement is turned to pass through the screen, which is a sieve, and the thickness is greater than the screen thickness. The thickness cannot pass through the screen. For some special long rope heads, flexible impurities such as straw hang on the screen, generally removed in time in time. Service Animal Husband From Material Sieve Status The necessary conditions: particles must be relatively slid on the screen; the particles should be sieved to have a chance to come into contact Screening; if separated by width, the particles desired by the desired sieve must be erected into the screen; The necessary conditions of the above screens are the three eleme of screening: 1 of the materials and sieves are relatively moved; 2 need to be sieved and sieved; 3 has suitable hole shape And size.
