Application of fish feed pellet extruder in drifting fish feed handling
In the last few years, the application of fish feed pellet extruder extrusion innovation to feed production is an epoch-making jump in feed manufacturing innovation. The primary benefits of extruded granulation:
( 1 )The processing temperature level is high as well as the wetness material is big, as well as the product can be completely developed and degraded. The pellets are of high quality as well as the feed titer is high;
( 2 )The flexible range of pellet thickness is big, which can adapt to the needs of numerous feeding items and various feeding settings.
( 1) Puffed suckling pig feed
The essential signs of suckling pig feed are health and also growth to prevent suckling pigs from looseness of the bowels. The raw products are treated with heat and also high pressure, on the one hand, it eliminates pathogenic bacteria, on the other hand, the starch material is totally prepared, as well as the soybean healthy protein is denatured and also cleansed, so that the product is easy to digest as well as take in. Gelatinized starch can boost the production of lactic acid in pets as well as improve the anti-bacterial capability of pets.

( 2) Extruded water feed
The aquatic feedl is extruded as well as granulated by fish feed pellet extruder, which boosts the quality of the product from all facets.
① Improved feed titer. Extrusion ripens the starch, which is essential for fish as raw starch is hard to digest. The starch is prepared, the cohesiveness of the material is improved, and also the forming result is great. On the facility of making certain the high quality of pellets, the formula can be adapted to lower prices.
② The floating time of pellets in water is controlled by the thickness of pellets, as well as the thickness is determined by the degree of puffing by fish feed pellet extruder.
Consequently, by readjusting the formula, readjusting the range as well as content of starch and binder, and also adjusting the procedure specifications, that is, adjusting the moisture, pressure, temperature level, and so on, extruded pellets with various densities can be produced.
( 3) Puffed chicken feed
The formula of chicken feed consists of high starch product as well as 15% -20% healthy protein product at the same time. For this proportion, despite the completely dry floating pellet machine or the damp drifting pellet maker, the technological efficiency is better.
Experiments have shown that blowing can enhance the digestion and also absorption price of feed for hens. Extruded chicken feed, because of its small mass thickness, can minimize chicken feed consumption, stay clear of excessive weight, as well as improve egg production.
( 4) Puffed cattle feed (urea puffed corn).
Ruminants such as cattle and also sheep can transform non-protein nitrogen (such as urea) into pet protein. The secret to adding urea to feed is just how to manage the enhancement quantity, consistent feed consumption and urea decomposition rate. Urea-expanded corn fixes these problems most successfully.
The urea, corn flour as well as additives are mixed in a certain percentage and afterwards go into the drifting pellet device, the corn flour is expanded, as well as the gelatinized starch and urea form a finishing framework. Urease inhibitors hinder the activity of urease. It prevents the launch price of ammonia after urea disintegration from 2 facets, and prevents ammonia poisoning caused by excess ammonia.
( 5) Rice bran preservation therapy.
Fresh rice bran consists of very active lipolytic enzymes, which can rapidly decay the oil included in rice bran into totally free lipids.
Fat and also rancidity, so the storage space performance of fresh rice bran is extremely poor. The rancid and also spoiled rice bran not just decreases the oil yield, but likewise influences the growth as well as advancement of livestock and poultry if fed as feed.
As a result, fresh rice bran should be kept fresh in time. Extrusion, high temperature, high pressure and high shear can inactivate lipase and avoid rancidity as well as wear and tear. Extrusion has become a brand-new pretreatment procedure in rice bran oil production.
( 6) Detoxing of oilseed meal healthy protein.
Along with soybean cake ( dish), the cake (meal) acquired from rapeseed, cottonseed, sunflower seed, castor as well as other oilseeds additionally includes a specific quantity of protein, which is an superb source of feed healthy protein. However, numerous oil cakes (including soybean meal) can not be directly made use of to formulate feed, since they all contain a specific quantity of anti-nutritional elements or other hazardous parts.
Oil cake ( dish) need to be cleansed prior to it can be utilized. Cleansing techniques consist of chemical and physical methods. Oilseed cake ( dish) extrusion detoxing is a modern innovation put on oil cake (meal) therapy by extrusion innovation.
( 7) Plume puffing processing.
As a result of the existence of disulfide bonds as well as hydrogen bonds between feather polypeptide chains, the structure of plume protein is especially stable, and animal digestive enzymes are essentially not able to absorb as well as decay, so the feather extrusion innovation has been established.
After the feather is extruded and puffed, its disulfide bond is broken, the molecular structure is ruined, and the digestion enzyme is very easy to digest and disintegrate, and the digestibility is improved. The digestibility is associated with the level of degradation and extrusion temperature.
When the drifting pellet device extrusion temperature is high, the digestibility of the puffed plume product rises, but the amino acid content of the product reduces likewise, and also the protein top quality of the product reduces.
Feather dish has high healthy protein web content, yet the amino acid is not stabilized enough. In order to solve this problem, poultry viscera, hen blood and also plumes can be combined as well as refined right into intestinal plume meal.
Fish feed pellet extruder squeezing out innovation is a feed handling technology created at the end of the 20th century. Pressure cutting has a great impact on controlling the density of extruded products, giving a brand-new approach for processing high-demand aquafeeds.
Making use of waste vapor as well as waste warm for conditioning makes the device extra environmentally friendly and also adapts to the fad of the times. Extrusion innovation of fish feed pellet extruder is extensively used in aquatic, swine and ruminant feeds, which has a significant result on transforming feed high quality as well as reducing costs.
With the development of fish feed pellet extruder extruding technology, even more thorough research is needed on how to accurately manage the expansiveness and extruding top quality of extruded feed, and also boost the automation of extruding.
