The issue of energy saving as well as usage decrease is the research study focus in the fish feed pellet extruder extrusion process.

Presently, it is mostly through the study of reduced energy usage processing technology and the impact of primary process parameters on energy consumption, and the establishment of equivalent mathematical models to attain the objective of energy saving and usage decrease.

In order to lower the power intake in the fish feed pellet extruder puffing process, some residential feed suppliers generally take measures from the process. For example, in the production process of nursing pig feed, the corn resources made use of is not complete puffed product, yet part of the puffed product and also part of the conventional product.

In the later fish feed pellet extruder granulation process, processes such as development and reduced temperature granulation are utilized to guarantee that the power intake per unit product is decreased.

From the above analysis, it can be seen that it is still a bottleneck issue exactly how the process parameter study in the fish feed pellet extruder puffing process can be embodied in lowering energy intake as well as can be understood in real manufacturing.

4. Application of extrusion in floating fish feed handling.

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

( 1 )The processing temperature level is high and the wetness material is large, and also the product can be fully developed as well as weakened. The pellets are of high quality and the feed titer is high;
( 2 )The adjustable series of pellet density is huge, which can adjust to the requirements of various feeding objects and various feeding atmospheres.

( 1) Puffed suckling pig feed

The important indications of suckling pig feed are hygiene and growth to prevent suckling pigs from diarrhea. The raw products are treated with heat as well as high pressure, on the one hand, it kills pathogenic microorganisms, on the other hand, the starch product is fully prepared, and the soybean protein is denatured and cleansed, to ensure that the product is easy to absorb and soak up. Gelatinized starch can promote the production of lactic acid in animals and improve the anti-bacterial ability of animals.

( 2) Extruded water feed
The water feedl is extruded and also granulated by fish feed pellet extruder, which boosts the top quality of the product from all facets.

① Boosted feed titer. Extrusion ripens the starch, which is important for fish as raw starch is hard to absorb. The starch is prepared, the cohesiveness of the product is improved, and the forming result is excellent. On the premise of guaranteeing the quality of pellets, the formula can be adjusted to decrease costs.

② The floating time of pellets in water is managed by the density of pellets, and the density is determined by the degree of puffing by fish feed pellet extruder.

For that reason, by changing the formula, adjusting the range and web content of starch and also binder, and adjusting the process specifications, that is, readjusting the moisture, stress, temperature, and so on, extruded pellets with different thickness can be generated.

The formula of chicken feed includes high starch product as well as 15% -20% healthy protein material at the same time. For this proportion, no matter the dry floating pellet machine or the damp floating pellet machine, the technological performance is much better.

Experiments have actually revealed that puffing can improve the food digestion and absorption rate of feed for poultries. Extruded chicken feed, because of its tiny bulk density, can reduce chicken feed intake, stay clear of excessive weight, and also boost egg manufacturing.

( 4) Puffed livestock feed (urea puffed corn).

Ruminants such as livestock and sheep can convert non-protein nitrogen (such as urea) into pet protein. The key to including urea to feed is just how to manage the enhancement quantity, consistent feed consumption and also urea disintegration rate. Urea-expanded corn addresses these problems most properly.

The urea, corn flour and also ingredients are mixed in a particular proportion and then go into the floating pellet machine, the corn flour is increased, and the gelatinized starch and also urea form a covering framework. Urease preventions inhibit the task of urease. It inhibits the launch rate of ammonia after urea decomposition from two facets, and stays clear of ammonia poisoning triggered by excess ammonia.

( 5) Rice bran conservation treatment.

Fresh rice bran contains very active lipolytic enzymes, which can swiftly decay the oil consisted of in rice bran into totally free lipids.

Fat and rancidity, so the storage performance of fresh rice bran is very inadequate. The rancid and ruined rice bran not only minimizes the oil yield, yet likewise impacts the development and also advancement of livestock as well as fowl if fed as feed.

For that reason, fresh rice bran should be maintained fresh in time. Extrusion, high temperature, high pressure and also high shear can suspend lipase and avoid rancidity and damage. Extrusion has become a brand-new pretreatment process in rice bran oil production.

( 6) Cleansing of oilseed meal protein.

In addition to soybean cake (meal), the cake (dish) obtained from rapeseed, cottonseed, sunflower seed, castor as well as various other oilseeds additionally contains a specific amount of healthy protein, which is a superb resource of feed protein. Nonetheless, numerous oil cakes (including soybean meal) can not be directly made use of to develop feed, because they all contain a specific amount of anti-nutritional aspects or other harmful components.

Oil cake (meal) should be cleansed before it can be utilized. Detoxification techniques include chemical as well as physical methods. Oilseed cake (meal) extrusion detoxing is a modern technology applied to oil cake (meal) treatment by extrusion modern technology.

( 7) Plume puffing handling.

Due to the existence of disulfide bonds and also hydrogen bonds between feather polypeptide chains, the framework of feather protein is particularly stable, as well as pet digestive enzymes are primarily unable to absorb and also decay, so the plume extrusion modern technology has actually been created.

After the feather is extruded as well as puffed, its disulfide bond is broken, the molecular framework is damaged, as well as the digestive system enzyme is very easy to absorb and break down, as well as the digestibility is boosted. The digestibility is associated with the degree of destruction and also extrusion temperature.

When the floating pellet machine extrusion temperature level is high, the digestibility of the puffed feather product rises, however the amino acid content of the product lowers likewise, and the healthy protein quality of the item reduces.

Plume meal has high healthy protein material, however the amino acid is not balanced sufficient. In order to resolve this problem, hen viscera, hen blood and also plumes can be mixed as well as refined into digestive tract plume dish.


Fish feed pellet extruder extruding technology is a feed processing modern technology created at the end of the 20th century. Pressure cutting has a great impact on managing the density of extruded items, providing a brand-new approach for processing high-demand aquafeeds.
