Application of fish feed pellet extruder in drifting fish feed processing
In recent years, the application of fish feed pellet extruder extrusion innovation to feed manufacturing is an epoch-making leap in feed manufacturing modern technology. The major benefits of extruded granulation:

( 1 )The processing temperature level is high and the moisture web content is huge, and the product can be fully matured and also deteriorated. The pellets are of good quality and the feed titer is high;
( 2 )The flexible series of pellet density is big, which can adapt to the requirements of various feeding objects as well as different feeding atmospheres.
( 1) Puffed suckling pig feed
The essential signs of nursing pig feed are health and maturation to avoid suckling pigs from looseness of the bowels. The raw materials are treated with high temperature and high pressure, on the one hand, it eliminates pathogenic germs, on the other hand, the starch material is fully cooked, as well as the soybean protein is denatured and cleansed, to make sure that the material is easy to absorb and soak up. Gelatinized starch can stimulate the production of lactic acid in animals and also boost the anti-bacterial capability of animals.

( 2) Extruded marine feed
The water feedl is extruded and also granulated by fish feed pellet extruder, which boosts the high quality of the item from all aspects.
① Boosted feed titer. Extrusion ripens the starch, which is essential for fish as raw starch is difficult to digest. The starch is prepared, the cohesiveness of the product is boosted, and the forming result is excellent. On the property of guaranteeing the quality of pellets, the formula can be gotten used to lower prices.
② The floating time of pellets in water is managed by the density of pellets, and the thickness is identified by the level of puffing by fish feed pellet extruder.
As a result, by adjusting the formula, readjusting the selection as well as material of starch and binder, as well as adjusting the procedure parameters, that is, adjusting the dampness, stress, temperature, etc, extruded pellets with various thickness can be generated.
( 3) Puffed chicken feed
The formula of chicken feed includes high starch product as well as 15% -20% protein material at the same time. For this proportion, no matter the dry drifting pellet equipment or the wet drifting pellet maker, the technological efficiency is better.

Experiments have actually revealed that puffing can enhance the digestion as well as absorption price of feed for poultries. Extruded chicken feed, because of its small mass thickness, can reduce chicken feed consumption, avoid weight problems, and also enhance egg production.
( 4) Puffed livestock feed (urea puffed corn).
Ruminants such as livestock as well as sheep can convert non-protein nitrogen (such as urea) right into animal protein. The trick to adding urea to feed is exactly how to regulate the addition amount, consistent feed consumption and also urea disintegration rate. Urea-expanded corn resolves these problems most successfully.
The urea, corn flour and ingredients are mixed in a certain proportion and after that go into the floating pellet device, the corn flour is broadened, and the gelatinized starch as well as urea develop a finish structure. Urease preventions prevent the task of urease. It prevents the launch rate of ammonia after urea disintegration from 2 elements, and also prevents ammonia poisoning caused by excess ammonia.

( 5) Rice bran conservation therapy.
Fresh rice bran has very active lipolytic enzymes, which can promptly decay the oil had in rice bran into totally free lipids.
Fatty acid as well as rancidity, so the storage space efficiency of fresh rice bran is very bad. The rancid and also ruined rice bran not only lowers the oil return, but likewise impacts the growth as well as advancement of animals as well as fowl if fed as feed.
Consequently, fresh rice bran must be kept fresh in time. Extrusion, high temperature, high pressure as well as high shear can suspend lipase and also stop rancidity and also deterioration. Extrusion has come to be a new pretreatment procedure in rice bran oil manufacturing.
( 6) Detoxification of oilseed dish protein.
Along with soybean cake (meal), the cake (meal) acquired from rapeseed, cottonseed, sunflower seed, castor and also various other oilseeds likewise consists of a certain amount of protein, which is an exceptional source of feed protein. Nevertheless, numerous oil cakes ( consisting of soybean meal) can not be directly used to create feed, due to the fact that they all contain a certain amount of anti-nutritional variables or other unsafe parts.
Oil cake ( dish) should be cleansed prior to it can be utilized. Detoxing approaches consist of chemical and physical methods. Oilseed cake (meal) extrusion cleansing is a contemporary innovation applied to oil cake ( dish) therapy by extrusion modern technology.

( 7) Plume puffing handling.
Due to the presence of disulfide bonds and also hydrogen bonds between plume polypeptide chains, the structure of feather healthy protein is especially steady, and animal digestive system enzymes are basically not able to absorb and also decay, so the plume extrusion modern technology has actually been developed.
After the plume is extruded as well as puffed, its disulfide bond is broken, the molecular structure is ruined, and also the digestive enzyme is very easy to absorb as well as decay, and the digestibility is improved. The digestibility is connected to the level of degradation and extrusion temperature level.
When the drifting pellet machine extrusion temperature level is high, the digestibility of the puffed plume item boosts, however the amino acid material of the product reduces likewise, and the protein high quality of the item lowers.
Feather dish has high protein material, however the amino acid is not stabilized sufficient. In order to address this issue, chicken viscera, poultry blood and plumes can be mixed and also refined right into intestinal plume dish.

Fish feed pellet extruder extruding technology is a feed handling modern technology created at the end of the 20th century. Stress cutting has a excellent result on controlling the thickness of extruded items, providing a brand-new technique for processing high-demand aquafeeds.
Using waste vapor and also waste heat for conditioning makes the equipment a lot more environmentally friendly and adapts to the fad of the moments. Extrusion modern technology of fish feed pellet extruder is widely made use of in water, swine as well as ruminant feeds, which has a considerable effect on transforming feed top quality as well as reducing costs.
With the advancement of fish feed pellet extruder squeezing out modern technology, even more comprehensive research study is needed on exactly how to precisely control the expansiveness and squeezing out quality of extruded feed, and enhance the automation of squeezing out.
