Author : Ball Villadsen | Published On : 30 Mar 2026

In the manufacturing of extruded feed, the main equipment is a screw fish feed pellet extruder. The material is fed right into the fish feed pellet extruder, and the screw screw pushes the material to form an axial flow.

At the same time, due to the mechanical friction in between the screw as well as the product, the product and the barrel, and also the product inside the product, the product is highly squeezed, mixed, as well as sheared, and also therefore, the material is additional improved and homogenized.

As the stress gradually raises, the temperature enhances as necessary. When the paste material is expelled from the die hole, under the activity of a solid pressure distinction, the material is puffed by floating fish feed making machine, dried out as well as cooled down. The puffed product hangs, porous, crisp, as well as has good palatability and also taste.

The fish feed pellet extruder puffing technology breaks through the typical handling modern technology, makes the physical properties of the feed change qualitatively, significantly advertises the advancement of the feed processing market as well as the breeding market, and also is a significant innovation in the feed industry.

The fish feed pellet extruder puffing process is a process that integrates numerous procedures such as mixing, working, shearing, home heating, and also air conditioning. The following is a certain evaluation from the facets of density control, automated control as well as power conserving and also intake reduction.

1. Thickness control modern technology

In the extrusion process of fish feed pellet extruder, there are lots of elements that impact the density of feed, such as refining innovation, fish feed pellet extruder equipment, processing criteria, process control, feed resources, formula and so on.

It is practical to control the item density by changing the raw material or formula, but it has little application worth; by altering the screw configuration, the thickness control of the extruded feed product can be understood, yet the operation is inconvenient. Thickness control can also be achieved by changing the operating parameters.

Additionally, in the fish feed pellet extruder handling of aquatic feed, in order to satisfy the feeding needs of aquatic animals, the ups as well as downs of aquatic feed should be regulated, as well as the ups and also downs of feed are very closely pertaining to thickness, so thickness control is used in the manufacturing of water extruded feed.

Innovation is specifically crucial. Presently, managing the density of extruded items is generally accomplished by controlling the pressure as well as temperature. The major approaches are as adheres to:

( 1 )Open a stress relief opening on the extruding dental caries, as well as plug the pressure relief opening when generating floating feed, so as to fulfill the needs of high temperature as well as high pressure for handling floating feed.

Open up the stress alleviation hole when feeding, to make sure that when the material gets to the pressure alleviation opening, the pressure in the sleeve is partly launched, and at the same time, some water vapor is additionally discharged from the pressure relief opening.


These products are extruded by fish feed pellet extruder throughout of the extruding dental caries and after that compressed to get a hefty feed with high mass density. This stress relief hole can also be used to leave, so that the material sheds part of the water vapor during the forced movement.


This fish feed pellet extruder process method recognizes the control of the density of the extruded item by managing the pressure in the extruding tooth cavity, and also the result will certainly not be impacted because the feeding quantity does not require to be decreased.

( 2) A stress managing tool is added in the floating fish feed extruder machine (pressurization before the die). The stress guideline of the fish feed pellet extruder is to mount a shut-off shutoff between the extrusion dental caries and the discharge template to readjust the pressure distinction in between the extrusion tooth cavity and the outside of the extrusion cavity.

( 2 )Stress cutting modern technology (post-mold stress). A new sort of density control system was established for aquafeed. This density control system of fish feed pellet extruder embraces pressurized reducing innovation to preserve a certain positive stress in the reducing chamber.

When the product enters the reducing chamber from the puffing chamber, because the boiling point of water boosts with the pressure, the flash dissipation can be decreased to control the level of development of the material, as well as the starch molecules are immediately solidified in the reducing chamber, as well as the product no more gets in the regular pressure from the cutting chamber.

The favorable pressure of the reducing chamber can be recognized by inputting compressed air with an air pump, as well as the fan can be turned off when discharging.

This fish feed pellet extruder process approach avoids controlling various other aspects that affect the level of growth, thus minimizing the requirement for manual operation, as well as at the same time, the controllability is more powerful than various other techniques.

Presently, this new fish feed pellet extruder innovation has actually not been applied in China, however this modern technology is superior to the exhaust method in regards to density control of extruded products as well as operation and also use, and also is a new direction for the growth of extruded technology.

( 4) Managing the opening price of the template. By changing the opening price of the discharge layout, the pressure distinction prior to and after the layout can be transformed, so regarding accomplish the purpose of managing the thickness of the item. The hole is blocked.

2. Automatic control of fish feed extrusion process

The automated control of the fish feed pellet extruder extrusion process refers to the rapid and also accurate control of the process parameters by gearing up 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 performance, but likewise boost product high quality security. Designs of automated control in the house and also abroad

There are research studies on all sides. The automatic control innovation of the fish feed pellet extruder puffing process has actually made fantastic progression, and also a visualization control system of the puffing process has been created. biomass pellet machine in Antigua and Barbuda extruding system of fish feed pellet extruder based upon FIX industrial arrangement software application recognizes the visual control of the extruding process

The sensing unit can be used to conduct on-site detection and comments on the operating criteria of the fish feed pellet extruder, immediately change the pertinent working parameters of the floating fish feed pellet machine, and also recognize various preset by the operator.

Functioning specifications, with formula storage, record printing, alarm, vibrant screen and recording of working criteria. Foreign computer system automatic control technology has currently been applied in the field of feed handling

In the entire fish feed pellet extruder process, it has actually been developed from a single computer system control system to an advanced automatic control system, which can show shade pictures in the main control space, computer program control and also communication network for floating fish feed making machine procedure, it can complete all manufacturing procedures without unmanned procedure.

In general, the automatic control of puffing in feed processing abroad has been creating towards the instructions of incorporating with product quality.

While the intro of computer systems in my country is mainly to resolve the issue of manufacturing automation, only focusing on the tracking of equipment operation in the production process as well as the control of stand-alone equipment. It has actually not played its due duty in enhancing item quality and other facets.

3. Power conserving in extrusion process.

The issue of energy conserving and consumption decrease is the study emphasis in the fish feed pellet extruder extrusion process.

Presently, it is mostly through the study of low energy usage handling innovation and the impact of main process parameters on power intake, as well as the establishment of equivalent mathematical versions to achieve the objective of energy saving as well as consumption decrease.

In order to lower the power usage in the fish feed pellet extruder puffing process, some residential feed manufacturers mostly take measures from the process. For example, in the manufacturing process of suckling pig feed, the corn raw material utilized is not complete puffed product, but part of the puffed product and part of the standard material.

In the later fish feed pellet extruder granulation process, processes such as development as well as reduced temperature level granulation are made use of to make sure that the energy consumption per unit product is decreased.

From the above analysis, it can be seen that it is still a traffic jam issue exactly how the process specification research in the fish feed pellet extruder puffing process can be embodied in lowering energy usage as well as can be understood in real manufacturing.

4. Application of extrusion in floating fish feed processing.

In the last few years, the application of fish feed pellet extruder extrusion modern technology to feed production is an epoch-making leap in feed production technology. The primary advantages of extruded granulation:

( 1 )The handling temperature level is high and the wetness material is huge, and also the material can be completely grown as well as weakened. The pellets are of high quality and also the feed titer is high;
( 2 )The flexible series of pellet density is large, which can adjust to the requirements of different feeding items and also different feeding environments.

( 1) Puffed suckling pig feed

The important indications of nursing pig feed are health and growth to prevent suckling pigs from looseness of the bowels. The raw materials are treated with high temperature as well as high pressure, on the one hand, it kills pathogenic microorganisms, on the other hand, the starch material is fully prepared, and also the soybean protein is denatured and also detoxed, to make sure that the material is simple to absorb and absorb. Gelatinized starch can stimulate the production of lactic acid in animals and improve the antibacterial capability of pets.

( 2) Extruded aquatic feed
The water feedl is extruded and granulated by fish feed pellet extruder, which improves the high quality of the item from all elements.

① Enhanced feed titer. Extrusion ripens the starch, which is important for fish as raw starch is challenging to digest. The starch is cooked, the cohesiveness of the material is boosted, and the creating result is great. On the premise of making certain the quality of pellets, the formula can be gotten used to reduce costs.

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

For that reason, by readjusting the formula, adjusting the selection and also content of starch and binder, and changing the process criteria, that is, readjusting the dampness, stress, temperature level, and so on, extruded pellets with different densities can be produced.

( 3) Puffed chicken feed

The formula of chicken feed has high starch product and also 15% -20% healthy protein product at the same time. For this percentage, despite the completely dry floating pellet machine or the wet floating pellet machine, the technical performance is better.

Experiments have shown that puffing can improve the food digestion as well as absorption rate of feed for poultries. Extruded chicken feed, because of its small mass thickness, can reduce chicken feed consumption, avoid weight problems, and also improve egg manufacturing.

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

Ruminants such as cattle and also sheep can transform non-protein nitrogen (such as urea) right into animal protein. The secret to adding urea to feed is exactly how to control the addition amount, consistent feed consumption as well as urea decomposition rate. Urea-expanded corn fixes these problems most efficiently.

The urea, corn flour as well as ingredients are mixed in a certain percentage and afterwards enter the floating pellet machine, the corn flour is expanded, and the gelatinized starch and also urea form a finishing framework. Urease inhibitors hinder the activity of urease. It hinders the launch rate of ammonia after urea decomposition from two aspects, as well as avoids ammonia poisoning caused by excess ammonia.

( 5) Rice bran conservation therapy.

Fresh rice bran consists of very energetic lipolytic enzymes, which can promptly decompose the oil had in rice bran right into free lipids.

Fat and rancidity, so the storage performance of fresh rice bran is very inadequate. The rancid and spoiled rice bran not just lowers the oil yield, but also impacts the development and also development of livestock as well as chicken if fed as feed.

For that reason, fresh rice bran must be kept fresh in time. Extrusion, high temperature, high pressure and high shear can inactivate lipase and also prevent rancidity and degeneration. Extrusion has ended up being a new pretreatment process in rice bran oil manufacturing.

( 6) Detoxification of oilseed meal protein.

In addition to soybean cake (meal), the cake (meal) gotten from rapeseed, cottonseed, sunflower seed, castor and various other oilseeds additionally contains a specific quantity of protein, which is an excellent source of feed healthy protein. Nevertheless, numerous oil cakes (including soybean dish) can not be straight utilized to formulate feed, because they all consist of a particular amount of anti-nutritional aspects or various other unsafe parts.

Oil cake (dish) have to be purified before it can be utilized. Cleansing techniques consist of chemical and also physical methods. Oilseed cake (dish) extrusion cleansing is a contemporary innovation put on oil cake (dish) treatment by extrusion modern technology.

( 7) Feather puffing handling.

Due to the existence of disulfide bonds and also hydrogen bonds between plume polypeptide chains, the framework of plume protein is especially secure, as well as animal digestive system enzymes are primarily unable to absorb as well as decay, so the plume extrusion modern technology has actually been developed.

After the feather is extruded and also puffed, its disulfide bond is broken, the molecular structure is destroyed, and the digestive system enzyme is easy to absorb as well as decompose, and also the digestibility is boosted. The digestibility is associated with the degree of destruction as well as extrusion temperature level.

When the floating pellet machine extrusion temperature level is high, the digestibility of the puffed plume item increases, yet the amino acid material of the item decreases likewise, and also the healthy protein top quality of the item decreases.

Feather dish has high protein web content, yet the amino acid is not stabilized enough. In order to address this problem, chicken viscera, poultry blood and feathers can be combined and processed right into intestinal plume dish.


Fish feed pellet extruder extruding technology is a feed handling innovation created at the end of the 20th century. Pressure cutting has a good result on controlling the density of extruded products, supplying a new approach for processing high-demand aquafeeds.

Using waste vapor as well as waste warm for conditioning makes the machine extra environmentally friendly as well as adapts to the pattern of the moments. Extrusion modern technology of fish feed pellet extruder is commonly utilized in aquatic, swine as well as ruminant feeds, which has a considerable impact on transforming feed top quality and reducing prices.

With the advancement of fish feed pellet extruder extruding modern technology, more thorough study is needed on just how to accurately control the expansiveness and extruding high quality of extruded feed, and also enhance the automation of extruding.
