Application of fish feed pellet extruder in floating fish feed handling
Over the last few years, the application of fish feed pellet extruder extrusion technology to feed manufacturing is an epoch-making jump in feed production technology. The main benefits of extruded granulation:

( 1 )The handling temperature level is high and the moisture material is big, and the product can be fully developed and also broken down. The pellets are of top quality and also the feed titer is high;
( 2 )The adjustable series of pellet density is huge, which can adjust to the needs of various feeding objects and also different feeding environments.
( 1) Puffed suckling pig feed
The vital signs of suckling pig feed are hygiene as well as growth to avoid suckling pigs from diarrhea. The raw products are treated with high temperature as well as high pressure, on the one hand, it kills pathogenic bacteria, on the other hand, the starch product is totally cooked, as well as the soybean healthy protein is denatured as well as detoxified, so that the material is very easy to digest and also soak up. Gelatinized starch can promote the manufacturing of lactic acid in animals as well as boost the anti-bacterial capacity of pets.

( 2) Extruded aquatic feed
The aquatic feedl is extruded as well as granulated by fish feed pellet extruder, which enhances the quality of the product from all aspects.
① Boosted feed titer. Extrusion ripens the starch, which is very important for fish as raw starch is challenging to absorb. The starch is prepared, the cohesiveness of the material is enhanced, as well as the creating impact is great. On the facility of making sure the top quality of pellets, the formula can be gotten used to reduce expenses.
② The floating time of pellets in water is regulated by the thickness of pellets, and the thickness is established by the degree of puffing by fish feed pellet extruder.
Therefore, by readjusting the formula, adjusting the variety as well as content of starch and also binder, and also readjusting the process parameters, that is, changing the dampness, stress, temperature level, and so on, extruded pellets with different densities can be generated.
( 3) Puffed chicken feed
The formula of chicken feed consists of high starch product and also 15% -20% healthy protein product at the same time. For this percentage, no matter the dry floating pellet device or the damp drifting pellet machine, the technical performance is much better.

Experiments have shown that puffing can boost the food digestion as well as absorption rate of feed for poultries. Extruded chicken feed, because of its small mass density, can decrease chicken feed intake, prevent obesity, and also boost egg manufacturing.
( 4) Puffed livestock feed (urea blown corn).
Ruminants such as cattle and lamb can transform non-protein nitrogen (such as urea) right into animal healthy protein. The trick to including urea to feed is how to regulate the enhancement amount, consistent feed consumption and urea decomposition rate. Urea-expanded corn fixes these problems most properly.
The urea, corn flour and also additives are mixed in a specific percentage and after that enter the floating pellet machine, the corn flour is expanded, and the gelatinized starch and urea create a finish framework. Urease preventions inhibit the activity of urease. It prevents the launch rate of ammonia after urea decomposition from 2 aspects, and also stays clear of ammonia poisoning triggered by excess ammonia.
( 5) Rice bran conservation therapy.
Fresh rice bran contains really active lipolytic enzymes, which can quickly decay the oil had in rice bran right into cost-free lipids.
Fat as well as rancidity, so the storage efficiency of fresh rice bran is very poor. The rancid and ruined rice bran not only lowers the oil yield, but additionally influences the growth as well as growth of livestock and poultry if fed as feed.
For that reason, fresh rice bran need to be kept fresh in time. Extrusion, high temperature, high pressure and also high shear can suspend lipase and avoid rancidity as well as wear and tear. Extrusion has come to be a brand-new pretreatment procedure in rice bran oil manufacturing.

( 6) Detoxification of oilseed meal healthy protein.
Along with soybean cake (meal), the cake ( dish) gotten from rapeseed, cottonseed, sunflower seed, castor and also other oilseeds additionally consists of a particular amount of healthy protein, which is an outstanding source of feed healthy protein. Nevertheless, various oil cakes (including soybean dish) can not be directly utilized to develop feed, since they all contain a particular amount of anti-nutritional variables or other unsafe components.
Oil cake (meal) must be purified prior to it can be utilized. Cleansing techniques include chemical and physical approaches. Oilseed cake (meal) extrusion detoxing is a modern-day technology put on oil cake (meal) therapy by extrusion modern technology.
( 7) Feather puffing processing.
As a result of the presence of disulfide bonds and hydrogen bonds in between plume polypeptide chains, the framework of feather protein is particularly secure, and also animal digestive system enzymes are essentially not able to digest as well as decompose, so the feather extrusion innovation has actually been developed.

After the plume is extruded and also puffed, its disulfide bond is damaged, the molecular framework is destroyed, and the digestive system enzyme is very easy to absorb as well as decay, and the digestibility is boosted. The digestibility is related to the degree of destruction and also extrusion temperature level.
When the drifting pellet machine extrusion temperature is high, the digestibility of the puffed feather product rises, yet the amino acid content of the item decreases likewise, and the healthy protein quality of the product lowers.
Plume meal has high protein web content, but the amino acid is not balanced enough. In order to solve this problem, hen viscera, chicken blood as well as feathers can be mixed and also refined into intestinal tract plume dish.
Fish feed pellet extruder extruding modern technology is a feed processing innovation established at the end of the 20th century. Pressure cutting has a excellent impact on regulating the density of extruded products, offering a brand-new technique for processing high-demand aquafeeds.

Using waste steam as well as waste warm for conditioning makes the machine more eco-friendly and also adapts to the pattern of the moments. Extrusion modern technology of fish feed pellet extruder is extensively utilized in aquatic, swine and also ruminant feeds, which has a significant impact on altering feed top quality as well as reducing costs.
With the growth of fish feed pellet extruder squeezing out technology, even more extensive study is needed on just how to precisely manage the expansiveness and also extruding quality of extruded feed, and also improve the automation of extruding.
