Extrusion Technology and Feed Production Process Control02020-06-29 00:36:16
Fish feed pellet machine,the main equipment is “screw extruder”. The main kinds are fish feed extruder, soybean/corn extruder, and feather extruder. Fish feed extruder is the common machine in thefish feed production line, which includes a single screw extruder and twin screw extruder. Extrusion Process And Main Kinds Applied In Feed Production The material is fed into the fish feed extruder and moves in the form of an axial flow under the screw power. At the same time, due to the mechanical friction between the screw and the material, the material and the barrel, and the material particles, the material is strongly squeezed, stirred, and sheared. As a result, the material is further refined and homogenized. With the gradual increase of pressure, the temperature rises accordingly. Under the condition of high temperature, high pressure, and high shear, the physical properties of the material have changed as follows: 1. From powder to paste. 2. Gelatinization of starch. 3. Protein denaturation. 4. Partial degradation and refinement of fiber. 5. Pathogenic bacteria were killed. 6. Health indicators are improved. 7. Toxic components were inactivated. When the paste material extruded from the die hole, under the influence of strong pressure difference, the material is expanded, dehydrated, and cooled. The final product is of loose and porous structure, crisp, good palatability, and flavor. Extrusion Process And Characteristics Of Extruded Products 1. Biochemical Process The process of hydrothermal treatment is accompanied by the biochemical change process of the material. Some materials, such as oilseeds and their cakes, contain a variety of anti-nutrients and anti-feeding ingredients. Under certain moisture and certain temperature conditions, these active substances gradually lose their activity, weakening the destruction of digestive enzymes inside the digestive system of animals, which improves absorption rate and reduces excretion. This not only improves the nutrition value of feed, but also reduces waste and environmental pollution. From the view of the biochemical process, the extruder is a “biochemical reactor.” 2. High-temperature and short-term germicidal detoxification process The highest temperature in the puffing process can reach(130-160) °C, while the material in the high-temperature segment is very short, about 5-10 seconds. High temperature can not only kill pathogens and health indications, but also can inactive a variety of harmful factors and enzymes, improving the feed quality. 3. Better chemical stability and longer quality guarantee period High temperatures cause various microorganisms and parasitic ovum to be killed and various enzymes( such ad oxidase, lipase, etc.) are inactivated. That excludes a wide range of factors that contribute to the deterioration of the material. 4. Wide range of process adaptability The extrusion process can not only improve the feeding quality of a variety of common feed materials, but also can process a large number of unconventional materials into high-quality feed materials, which include wild plants, agricultural by-product, slaughter waste and of livestock and poultry, etc. Fish feed extruder can produce a variety of different specifications and quality of livestock poultry materials, aquatic feed, pets feed, etc. At the same time, the extrusion process is also the most effective technique for the detoxification, preservation, and processing of grain cakes and deep processing of grain. 5. High-grade product features Extrusion products are loose and crunchy after being cooled, composite products produced by various components, and Maillard reaction due to high temperature. All these factors constitute better palatability over the original mixture and  have a special flavor. These characteristics induce animal feed to intake, thus increasing feed intake and feed effectiveness. This is completely different from the addition of phagostimulant to the mixture, which often has negative effects. 6. It can produce special feed with different shape According to the user’s requirements, changing the model design can produce different shapes of large particles, large blocks or bar-like materials, such as prawn feed, pet feed, rare animal feed, etc. This is what the ring die pellet machine can’t do. 7. Higher digestion rate For those suckling pigs whose digestive system is not well developed, the starch in the weaning material requires the gelatinization degree of more than 90%. And the aquatic animals also requires the gelatinization degree of the feed should also be higher because their absorption capacity of the original degree is poor. Extruder machine can realize it well. Therefore, it is better to use extruder than ring die pellet machine to produce aquatic products because due to the temperature restriction, the gelatinization degree of starch processed by ring die pellet machine can not be high, which is generally no more than 50%. Gelatinization not only improves digestibility, but also improves granulation and shaping because dextrins are good binders. The gelatinized starch molecules crosslink each other to form a network-like spatial structure, lose some moisture after being instantaneously expanded, and become a skeleton of the expanded product after cooling, so that the product maintains a certain shape.

Application Of Feed Hammer Mill In The Feed Pellet Production Technology02019-11-07 22:36:26
Feed hammer mill is a kind of common feed crushing processing machinery, it can use to crush crops, straw, corn, soybean, and other feed raw materials, users can choose the appropriate diameter of the hammer according to the actual processing needs for replacement. At present, there are two kinds of crushing technology: first crushing and then batching, first batching and then crushing, or the comprehensive application of the two kinds of technology. First Crushing And Then Batching Of The Feed Hammer Mill The first crushing process mainly used for the majority of livestock and poultry feed. The characteristics of the process are according to the nature of raw materials to configure the corresponding feed grinder, in order to obtain economic rationality. First Batching And Then Crushing Because many raw materials in the formula of aquatic feed contain high protein and oil, if the raw materials through the first crushing process, the oil in the raw materials will easily block the small screen holes on the screen of the hammer crusher. So the first crushing process is not suitable for the crushing of such raw materials.The post-crushing process can better solve the problems in the pre-crushing system. After the mixing of various raw materials, their physical properties play a complementary role. The direct mixing of materials after crushing can save the distribution bin and eliminate the arch phenomenon of materials in the bin. The above characteristics make most aquatic feed mills tend to use the post-crushing process.Of course, after the use of the post-crushing process, crushing equipment must configure according to the hardest raw materials in the ingredients. So some soft raw materials will produce excessive crushing, not only increase the crushing energy consumption but also reduce the crushing efficiency. So as to accelerate the grinding equipment, especially the hammer wear. Comprehensive Application Of The Two Kinds Of Technology In the design of the crushing process, the first crushing and thenthe crushing process can also apply comprehensively, which is especially suitable for the materials requiring micro-crushing.Coarsely crush the granular raw materials that need to be crushed, and then mix them with other powdered raw materials, which is a benefit to the even mixing and micro-crushing of the materials. After the second crushing of the material, it needs to be mixed again, which can improve the mixing evenness of the material and the quality of the product. Replace The Hammer Piece Of Wearing Parts Hammer of replacement parts is more convenient, only according to the product manual attached to the purchase of feed crusher machine, it can be easily replaced. The hammer type feed crusher can crush the materials once and twice. The feed material that needs to crush is first crushed and entered into the batching bin. Feed ingredients that do not need to crush can directly feed into the feed bin of the feed pellet machine, then carry out the mixing and other processes. Because of its secondary pulverization characteristics, the feed ingredients can crush more thoroughly and delicately, and animal feeding is easier, thereby increasing the feed intake of the animals. In general, for crushing raw materials of different thicknesses, the feed crushing machine needs to use hammers of different specifications (the main difference is the pore size of the hammer), so as to better crush the material.

Organic Fertilizer Production Line Organic Fertilizer Fermentation Technology02019-10-22 23:42:23
Organic fertilizers contain organic matter, which can provide a variety of inorganic nutrients and organic nutrients for crops, as well as fertilizer and improve the soil. Most of them are farmed locally and are self-contained. Zhengzhou Fusmar Machinery is a professional fertilizer granulator machine manufacturer. The following describes the fermentation technology of organic fertilizers. The Organic Fertilizer Raw Materials The manure and other materials, domestic garbage, sludge, and other fertilizer base materials piled on the flat ground in strips. The trough type turning machine directly puts the material into the tank, the stack width and the equipment stacking width are equal, the height is as high as possible, and the length is as long as possible, such as 50 meters, 100 meters, and so on.The ground can be cement and land, as long as it is level, there is a certain hardness. For every 10,000 tons of production required 5-6 acres of land, the trough type of throwing machine relatively small. The piled livestock manure and other materials, domestic garbage, sludge, and other fertilizer base materials sprinkled with beneficial bacterial fertilizer fermentation. Organic Fertilizer Production Line Fermentation Technology Mixed the straw manure and other materials, domestic garbage, sludge, fermenting bacteria, and so on. With a turning machine or trough-type throwing machine, and deodorize them in 3-5 hours, and heat up to 50 degrees in 16 hours. When the temperature reaches 55 degrees, the oxygen turned up again, and then the mixture starts to mix. When the temperature of the material reaches 55 degrees and the effect of uniform fermentation. Oxygenation and temperature reduction repeated, and the last process repeated until completely decomposed. If the water content of livestock manure and other materials, domestic garbage, sludge, etc. is too high, it is possible to add an auxiliary material containing organic matter. Which is relatively dry to absorb moisture, or to use a reflux method to place the last dried fertilizer underneath to form a strip. In the shape, the manure and other materials with large water content and other materials, domestic garbage, sludge, etc. are placed in the middle, so that the above water seeps below and then turned over. Organic Fertilizer Production Line Equipment The general fertilization process takes 10-15 days. Due to the different climates, it may take 15-20 days. The materials completely decomposed, and truly achieve no odor, no pathogens, no weed seeds, high humus, potassium content increased. Powdered organic fertilizer is made. If the powdered fertilizer wants to make into granular fertilizer, organic fertilizer production line necessary to add equipment such as disc granulator, fertilizer crusher machine, grading sieve, dryer, cooling machine, automatic packaging machine, belt conveyor, and so on.
