In the production of extruded feed, the main equipment is a screw fish feed pellet extruder. The material is fed into the fish feed pellet extruder, and also the screw screw pushes the product to develop an axial flow.At the same time, as a result of the mechanical friction in between the screw as well as the product, the product and also the barrel, as well as the material inside the product, the product is strongly pressed, stirred, and sheared, and consequently, the material is more improved as well as homogenized.As the stress slowly raises, the temperature level increases as necessary. When the paste product is ejected from the die opening, under the activity of a solid stress distinction, the product is puffed by floating fish feed making machine, dehydrated and also cooled down. The puffed item hangs, permeable, crisp, and also has excellent palatability and also flavor.The fish feed pellet extruder puffing technology breaks through the traditional processing modern technology, makes the physical residential properties of the feed modification qualitatively, substantially promotes the advancement of the feed handling market and also the breeding industry, and also is a significant development in the feed industry.The fish feed pellet extruder puffing process is a process that incorporates numerous procedures such as mixing, working, shearing, heating, as well as cooling. The following is a specific evaluation from the elements of thickness control, automatic control as well as energy conserving as well as consumption decrease.1. Thickness control modern technologyIn the extrusion process of fish feed pellet extruder, there are lots of aspects that affect the density of feed, such as processing innovation, fish feed pellet extruder equipment, refining specifications, process control, feed resources, formula and more.It is practical to manage the product thickness by transforming the raw product or formula, but it has little application worth; by transforming the screw arrangement, the density control of the extruded feed product can be realized, but the procedure is inconvenient. Thickness control can also be attained by adjusting the operating specifications.In addition, in the fish feed pellet extruder handling of marine feed, in order to fulfill the feeding demands of aquatic animals, the ups and downs of water feed should be managed, as well as the ups as well as downs of feed are closely pertaining to density, so thickness control is applied in the production of aquatic extruded feed.Technology is especially vital. At present, regulating the density of extruded items is primarily accomplished by managing the stress as well as temperature level. The major methods are as follows:( 1 )Open a pressure alleviation opening on the extruding cavity, and also connect the stress alleviation hole when producing floating feed, so as to fulfill the requirements of heat and high pressure for handling floating feed.Open up the stress alleviation hole when feeding, so that when the product reaches the stress alleviation hole, the stress in the sleeve is partly launched, as well as at the same time, some water vapor is likewise discharged from the pressure alleviation hole.These products are extruded by fish feed pellet extruder throughout of the extruding tooth cavity and then compacted to acquire a heavy feed with high bulk density. This stress alleviation opening can also be utilized to leave, to ensure that the material sheds part of the water vapor throughout the forced activity.This fish feed pellet extruder process approach understands the control of the thickness of the extruded product by regulating the stress in the extruding cavity, as well as the outcome will certainly not be influenced due to the fact that the feeding amount does not need to be decreased.( 2) A stress managing tool is included the floating fish feed extruder machine (pressurization prior to the die). The pressure law of the fish feed pellet extruder is to set up a shut-off shutoff in between the extrusion cavity and also the discharge template to readjust the stress difference in between the extrusion dental caries and also the beyond the extrusion cavity.( 2 )Pressure cutting innovation (post-mold stress). A new sort of density control system was created for aquafeed. This density control system of fish feed pellet extruder takes on pressurized cutting innovation to keep a particular positive pressure in the cutting chamber.When the product gets in the cutting chamber from the puffing chamber, since the boiling point of water raises with the stress, the flash evaporation can be decreased to regulate the level of expansion of the material, as well as the starch particles are instantaneously solidified in the cutting chamber, as well as the material no longer enters the normal stress from the reducing chamber.The positive stress of the reducing chamber can be recognized by inputting pressed air with an air pump, and the follower can be shut off when discharging.This fish feed pellet extruder process approach prevents managing various other elements that affect the degree of expansion, thus decreasing the demand for hand-operated operation, as well as at the same time, the controllability is stronger than various other techniques.Presently, this brand-new fish feed pellet extruder innovation has actually not been used in China, but this innovation transcends to the exhaust technique in regards to thickness control of extruded items as well as operation as well as usage, and also is a brand-new direction for the advancement of extruded innovation.( 4) Managing the opening price of the layout. By altering the opening rate of the discharge theme, the pressure difference before and also after the template can be changed, so regarding achieve the objective of controlling the thickness of the product. The hole is obstructed.2. Automatic control of fish feed extrusion processThe automated control of the fish feed pellet extruder extrusion process describes the quick and specific control of the process parameters by outfitting the extrusion equipment with a computer-aided control system.The application of automated control technology in the fish feed pellet extruder puffing process can not just enhance job effectiveness, however additionally boost product quality security. Designs of automated control in the house and abroadThere are studies on all sides. The automated control innovation of the fish feed pellet extruder puffing process has actually made fantastic progress, as well as a visualization control system of the puffing process has been established. The extruding system of fish feed pellet extruder based on repair industrial configuration software application recognizes the visual control of the extruding processThe sensor can be made use of to carry out on-site detection as well as responses on the operating parameters of the fish feed pellet extruder, immediately adjust the pertinent working criteria of the floating fish feed pellet machine, and also understand various predetermined by the driver.Functioning specifications, with formula storage, record printing, alarm, dynamic display screen as well as recording of working parameters. International computer system automatic control modern technology has actually already been applied in the field of feed handlingIn the whole fish feed pellet extruder process, it has actually been developed from a solitary computer control system to an innovative automated control system, which can show shade pictures in the central control area, computer program control as well as communication network for floating fish feed making machine procedure, it can complete all manufacturing procedures without unmanned procedure.Generally, the automated control of puffing in feed handling abroad has actually been establishing towards the instructions of integrating with product quality.While the introduction of computer systems in my country is mainly to address the issue of manufacturing automation, just concentrating on the surveillance of equipment operation in the production process and the control of stand-alone equipment. It has not played its due duty in improving product quality and also other elements.3. Energy saving in extrusion process.The problem of power conserving as well as usage reduction is the study focus in the fish feed pellet extruder extrusion process.At present, it is generally with the research of reduced energy intake handling innovation and the influence of major process criteria on energy usage, and also the establishment of equivalent mathematical designs to accomplish the function of energy saving as well as intake decrease.In order to decrease the power consumption in the fish feed pellet extruder puffing process, some domestic feed makers mostly take measures from the process. For example, in the manufacturing process of nursing pig feed, the corn basic material made use of is not complete puffed material, yet part of the puffed material as well as part of the traditional product.In the later fish feed pellet extruder granulation process, processes such as growth and also reduced temperature granulation are made use of to make certain that the power usage per unit product is minimized.From the above evaluation, it can be seen that it is still a traffic jam problem how the process specification study in the fish feed pellet extruder puffing process can be embodied in minimizing energy usage and also can be understood in actual manufacturing.4. Application of extrusion in floating fish feed processing.In recent years, the application of fish feed pellet extruder extrusion technology to feed manufacturing is an epoch-making jump in feed production technology. The major benefits of extruded granulation:( 1 )The handling temperature level is high as well as the wetness content is big, and the material can be totally matured as well as deteriorated. The pellets are of good quality as well as the feed titer is high;( 2 )The adjustable series of pellet thickness is big, which can adapt to the needs of numerous feeding objects and various feeding settings.( 1) Puffed suckling pig feedThe essential signs of suckling pig feed are hygiene and also growth to avoid suckling pigs from diarrhea. The raw products are treated with high temperature and high pressure, on the one hand, it kills pathogenic germs, on the other hand, the starch product is totally prepared, and the soybean protein is denatured and also cleansed, so that the product is simple to digest as well as take in. Gelatinized starch can promote the manufacturing of lactic acid in pets and boost the antibacterial ability of animals.( 2) Extruded marine feedThe aquatic feedl is extruded as well as granulated by fish feed pellet extruder, which improves the high quality of the product from all facets.① Enhanced feed titer. Extrusion ripens the starch, which is essential for fish as raw starch is tough to digest. The starch is cooked, the cohesiveness of the product is boosted, and the developing effect is good. On the facility of making certain the high quality of pellets, the formula can be adjusted to minimize costs.② The floating time of pellets in water is regulated by the thickness of pellets, and also the thickness is determined by the level of puffing by fish feed pellet extruder.Consequently, by adjusting the formula, adjusting the range and also web content of starch as well as binder, and also adjusting the process criteria, that is, readjusting the dampness, stress, temperature level, etc, extruded pellets with various thickness can be created.( 3) Puffed chicken feedThe formula of chicken feed includes high starch material and also 15% -20% protein material at the same time. For this proportion, despite the dry floating pellet machine or the wet floating pellet machine, the technical efficiency is better.Experiments have revealed that puffing can boost the food digestion and absorption price of feed for chickens. Extruded chicken feed, because of its tiny bulk density, can minimize chicken feed consumption, prevent weight problems, and boost egg manufacturing.( 4) Puffed cattle feed (urea puffed corn).Ruminants such as cattle and also lamb can convert non-protein nitrogen (such as urea) right into pet healthy protein. The secret to including urea to feed is exactly how to regulate the enhancement quantity, uniform feed intake as well as urea decay rate. Urea-expanded corn addresses these issues most successfully.The urea, corn flour as well as ingredients are mixed in a particular percentage and afterwards go into the floating pellet machine, the corn flour is broadened, as well as the gelatinized starch and also urea create a covering framework. Urease preventions hinder the activity of urease. It hinders the launch rate of ammonia after urea decay from 2 elements, as well as prevents ammonia poisoning caused by excess ammonia.( 5) Rice bran preservation therapy.Fresh rice bran consists of really active lipolytic enzymes, which can rapidly decompose the oil contained in rice bran right into cost-free lipids.Fatty acid as well as rancidity, so the storage performance of fresh rice bran is exceptionally inadequate. The rancid as well as spoiled rice bran not just minimizes the oil return, however likewise affects the development and growth of animals and poultry if fed as feed.For that reason, fresh rice bran have to be kept fresh in time. Extrusion, heat, high pressure as well as high shear can inactivate lipase as well as protect against rancidity as well as deterioration. Extrusion has come to be a brand-new pretreatment process in rice bran oil manufacturing.( 6) Cleansing of oilseed meal protein.In Richi Manufacture to soybean cake (meal), the cake (meal) obtained from rapeseed, cottonseed, sunflower seed, castor and also other oilseeds also includes a particular amount of protein, which is an excellent resource of feed protein. Nevertheless, numerous oil cakes (consisting of soybean dish) can not be directly utilized to develop feed, due to the fact that they all contain a particular amount of anti-nutritional aspects or various other harmful parts.Oil cake (meal) should be detoxified prior to it can be used. Cleansing techniques include chemical and physical methods. Oilseed cake (dish) extrusion cleansing is a modern innovation applied to oil cake (dish) treatment by extrusion innovation.( 7) Feather puffing handling.Because of the existence of disulfide bonds and also hydrogen bonds between feather polypeptide chains, the structure of plume protein is specifically secure, as well as animal digestion enzymes are generally not able to absorb and decay, so the feather extrusion innovation has actually been established.After the feather is extruded and puffed, its disulfide bond is broken, the molecular structure is ruined, and also the digestion enzyme is simple to digest and also disintegrate, and also the digestibility is improved. The digestibility is connected to the degree of destruction and extrusion temperature level.When the floating pellet machine extrusion temperature is high, the digestibility of the puffed feather item increases, but the amino acid content of the item decreases correspondingly, as well as the protein quality of the product lowers.Feather dish has high protein content, yet the amino acid is not stabilized enough. In order to address this trouble, hen viscera, hen blood and also plumes can be mixed and also processed into intestinal tract feather dish.Fish feed pellet extruder extruding innovation is a feed processing innovation established at the end of the 20th century. Stress cutting has an excellent impact on regulating the thickness of extruded items, supplying a new approach for processing high-demand aquafeeds.Using waste vapor and also waste heat for conditioning makes the machine extra eco-friendly and also adapts to the trend of the moments. Extrusion innovation of fish feed pellet extruder is extensively used in marine, swine and also ruminant feeds, which has a significant impact on transforming feed quality and reducing prices.With the advancement of fish feed pellet extruder extruding modern technology, more comprehensive study is required on just how to properly regulate the expansiveness and also extruding quality of extruded feed, and improve the automation of extruding.
