Author : Link Deleuran | Published On : 17 Mar 2026

In the manufacturing of extruded feed, the major equipment is a screw fish feed pellet extruder. The product is fed into the fish feed pellet extruder, as well as the screw screw presses the material to develop an axial flow.

At the same time, because of the mechanical friction in between the screw and also the material, the material and also the barrel, and also the product inside the material, the material is highly pressed, mixed, and also sheared, and because of this, the material is further fine-tuned as well as homogenized.

As the stress progressively increases, the temperature boosts as necessary. When the paste material is ejected from the die hole, under the action of a strong pressure difference, the product is puffed by floating fish feed making machine, dried out as well as cooled. The puffed product hangs, porous, crisp, as well as has excellent palatability and flavor.

The fish feed pellet extruder puffing technology appear the typical handling modern technology, makes the physical homes of the feed change qualitatively, substantially promotes the advancement of the feed processing industry and also the breeding industry, and also is a significant innovation in the feed sector.

The fish feed pellet extruder puffing process is a process that incorporates numerous operations such as mixing, massaging, shearing, home heating, and also air conditioning. The following is a certain evaluation from the elements of thickness control, automated control as well as power conserving and also usage reduction.

1. Density control technology

In the extrusion process of fish feed pellet extruder, there are numerous variables that affect the thickness of feed, such as processing technology, fish feed pellet extruder equipment, refining specifications, process control, feed raw materials, formula and so on.

It is possible to regulate the product thickness by altering the raw material or formula, but it has little application worth; by altering the screw arrangement, the thickness control of the extruded feed product can be understood, yet the operation is bothersome. Density control can likewise be attained by adjusting the operating specifications.

On top of that, in the fish feed pellet extruder processing of aquatic feed, in order to satisfy the feeding requirements of marine pets, the ups and downs of water feed should be managed, as well as the ups and downs of feed are very closely related to thickness, so thickness control is applied in the manufacturing of marine extruded feed.

Modern technology is especially essential. Today, managing the density of extruded items is mainly accomplished by controlling the pressure and temperature level. The primary approaches are as complies with:

( 1 )Open a stress relief opening on the extruding tooth cavity, and connect the stress relief opening when generating floating feed, so as to meet the demands of heat and also high pressure for processing floating feed.

Open the stress alleviation hole when feeding, to make sure that when the product gets to the stress alleviation opening, the pressure in the sleeve is partially released, and at the same time, some water vapor is also discharged from the stress relief hole.


These products are extruded by fish feed pellet extruder to the end of the extruding dental caries and afterwards compacted to obtain a heavy feed with high bulk thickness. This stress alleviation opening can also be used to leave, to ensure that the product loses part of the water vapor throughout the forced movement.

This fish feed pellet extruder process method realizes the control of the thickness of the extruded product by regulating the stress in the extruding tooth cavity, and also the result will not be influenced since the feeding quantity does not need to be lowered.

( 2) A stress managing device is included the floating fish feed extruder machine (pressurization before the die). The stress guideline of the fish feed pellet extruder is to install a shut-off valve in between the extrusion tooth cavity as well as the discharge template to readjust the pressure distinction in between the extrusion tooth cavity and also the outside of the extrusion cavity.

( 2 )Pressure reducing innovation (post-mold stress). A new kind of density control system was created for aquafeed. This thickness control system of fish feed pellet extruder takes on pressurized cutting modern technology to preserve a particular positive pressure in the reducing chamber.

When the product enters the cutting chamber from the puffing chamber, since the boiling point of water raises with the stress, the flash dissipation can be decreased to manage the level of expansion of the material, and the starch molecules are immediately strengthened in the reducing chamber, and the product no longer goes into the normal pressure from the cutting chamber.

The positive pressure of the cutting chamber can be recognized by inputting compressed air with an air pump, and also the fan can be shut off when releasing.

This fish feed pellet extruder process technique avoids managing various other aspects that impact the level of expansion, thus reducing the requirement for manual procedure, and also at the same time, the controllability is more powerful than other approaches.

At present, this brand-new fish feed pellet extruder technology has not been used in China, but this technology is superior to the exhaust method in terms of thickness control of extruded items as well as procedure and also usage, and also is a brand-new instructions for the growth of extruded innovation.

( 4) Controlling the opening rate of the template. By transforming the opening price of the discharge theme, the pressure distinction before as well as after the layout can be transformed, so as to achieve the purpose of regulating the density of the product. The hole is obstructed.

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 specifications by gearing up the extrusion equipment with a computer-aided control system.

The application of automatic control innovation in the fish feed pellet extruder puffing process can not only boost work performance, yet likewise improve item quality stability. Designs of automatic control in your home and abroad

There are researches on all sides. The automated control technology of the fish feed pellet extruder puffing process has actually made excellent progress, and also a visualization control system of the puffing process has actually been established. The extruding system of fish feed pellet extruder based on solution commercial setup software realizes the aesthetic control of the extruding process

The sensor can be utilized to perform on-site discovery and also feedback on the operating parameters of the fish feed pellet extruder, instantly readjust the appropriate functioning criteria of the floating fish feed pellet machine, as well as recognize numerous predetermined by the operator.

Working parameters, with formula storage space, record printing, alarm system, dynamic display as well as recording of functioning specifications. Foreign computer automated control modern technology has actually currently been used in the field of feed handling

In the whole fish feed pellet extruder process, it has been developed from a solitary computer system control system to an advanced automated control system, which can present shade photos in the central control area, computer system program control and interaction network for floating fish feed making machine procedure, it can finish all production treatments without unmanned procedure.

Generally, the automatic control of puffing in feed processing abroad has been establishing in the direction of the direction of combining with product quality.

While the intro of computers in my nation is generally to fix the trouble of manufacturing automation, just concentrating on the tracking of equipment operation in the production process as well as the control of stand-alone equipment. It has not played its due function in enhancing product top quality and other aspects.

3. Power saving in extrusion process.

The issue of power conserving and usage decrease is the study focus in the fish feed pellet extruder extrusion process.

At present, it is generally with the research of reduced power intake processing modern technology as well as the impact of primary process parameters on energy usage, and also the establishment of corresponding mathematical versions to achieve the function of energy conserving and consumption reduction.

In order to decrease the energy consumption in the fish feed pellet extruder puffing process, some residential feed suppliers mostly take measures from the process. For example, in the production process of suckling pig feed, the corn raw material utilized is not full puffed material, however part of the puffed material and also part of the conventional material.

In the later fish feed pellet extruder granulation process, processes such as growth as well as reduced temperature granulation are used to make certain that the energy intake per unit product is reduced.

From the above analysis, it can be seen that it is still a bottleneck problem how the process parameter research in the fish feed pellet extruder puffing process can be symbolized in lowering energy consumption and can be understood in real manufacturing.

4. Application of extrusion in floating fish feed processing.

Recently, the application of fish feed pellet extruder extrusion technology to feed production is an epoch-making leap in feed production technology. The major benefits of extruded granulation:

( 1 )The handling temperature level is high and the moisture content is huge, as well as the product can be completely grown and also broken down. The pellets are of high quality and also the feed titer is high;
( 2 )The flexible range of pellet thickness is big, which can adapt to the demands of different feeding objects and also different feeding environments.

( 1) Puffed suckling pig feed

The important indications of suckling pig feed are health and maturation to prevent suckling pigs from diarrhea. The raw materials are treated with high temperature and high pressure, on the one hand, it kills pathogenic bacteria, on the other hand, the starch material is completely cooked, as well as the soybean healthy protein is denatured as well as cleansed, to make sure that the material is easy to absorb and absorb. Gelatinized starch can promote the manufacturing of lactic acid in animals and 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 improves the quality of the product from all facets.

① Boosted feed titer. Extrusion ripens the starch, which is necessary for fish as raw starch is tough to absorb. The starch is cooked, the cohesiveness of the material is enhanced, as well as the forming impact is excellent. On the premise of making sure the high quality of pellets, the formula can be gotten used to reduce costs.

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

As a result, by adjusting the formula, readjusting the selection and material of starch and also binder, and changing the process specifications, that is, changing the dampness, stress, temperature, and so on, extruded pellets with various thickness can be produced.

( 3) Puffed chicken feed

The formula of chicken feed includes high starch material as well as 15% -20% protein product at the same time. For this percentage, regardless of the dry floating pellet machine or the damp floating pellet machine, the technological efficiency is better.

Experiments have revealed that puffing can enhance the digestion and also absorption rate of feed for hens. Extruded chicken feed, as a result of its little mass density, can reduce chicken feed intake, stay clear of weight problems, and enhance 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 healthy protein. The key to adding urea to feed is exactly how to regulate the enhancement amount, consistent feed consumption and also urea disintegration price. Urea-expanded corn solves these issues most successfully.

The urea, corn flour as well as additives are mixed in a particular percentage and then go into the floating pellet machine, the corn flour is increased, and the gelatinized starch and urea create a finishing structure. Urease inhibitors hinder the activity of urease. pellet mill machine prevents the launch rate of ammonia after urea decay from 2 aspects, and prevents ammonia poisoning brought on by excess ammonia.

( 5) Rice bran preservation treatment.

Fresh rice bran consists of very energetic lipolytic enzymes, which can rapidly decay the oil contained in rice bran right into complimentary lipids.

Fatty acid and rancidity, so the storage space performance of fresh rice bran is incredibly inadequate. The rancid and ruined rice bran not only reduces the oil return, however additionally influences the development and also growth of livestock and also chicken if fed as feed.

Consequently, fresh rice bran should be maintained fresh in time. Extrusion, high temperature, high pressure and also high shear can inactivate lipase and avoid rancidity as well as wear and tear. Extrusion has actually come to be a new pretreatment process in rice bran oil production.

( 6) Detoxification of oilseed dish healthy protein.

Along with soybean cake (dish), the cake (meal) gotten from rapeseed, cottonseed, sunflower seed, castor as well as various other oilseeds additionally consists of a specific amount of protein, which is a superb source of feed protein. Nonetheless, numerous oil cakes (including soybean meal) can not be directly made use of to create feed, due to the fact that they all have a certain quantity of anti-nutritional variables or other harmful parts.

Oil cake (meal) must be detoxed prior to it can be made use of. Detoxification techniques include chemical and physical techniques. Oilseed cake (dish) extrusion cleansing is a contemporary technology related to oil cake (dish) therapy by extrusion innovation.

( 7) Plume puffing handling.

Because of the existence of disulfide bonds as well as hydrogen bonds between plume polypeptide chains, the structure of plume healthy protein is especially steady, as well as animal digestion enzymes are essentially unable to absorb and disintegrate, so the plume extrusion technology has actually been created.

After the feather is extruded and puffed, its disulfide bond is damaged, the molecular framework is damaged, and the gastrointestinal enzyme is very easy to digest and also disintegrate, as well as the digestibility is boosted. The digestibility is connected to the level of destruction and extrusion temperature level.

When the floating pellet machine extrusion temperature is high, the digestibility of the puffed plume item rises, yet the amino acid content of the product lowers alike, as well as the protein quality of the item reduces.

Plume meal has high protein web content, however the amino acid is not stabilized sufficient. In order to resolve this issue, chicken viscera, poultry blood as well as feathers can be mixed and also processed right into digestive feather dish.



Fish feed pellet extruder extruding modern technology is a feed processing modern technology created at the end of the 20th century. Stress cutting has a good result on managing the density of extruded items, giving a brand-new technique for processing high-demand aquafeeds.

Making use of waste vapor and waste heat for conditioning makes the machine extra environmentally friendly and also adapts to the trend of the times. Extrusion innovation of fish feed pellet extruder is widely used in water, swine and also ruminant feeds, which has a substantial result on altering feed high quality and decreasing costs.

With the growth of fish feed pellet extruder extruding modern technology, more thorough research study is needed on just how to accurately control the expansiveness and extruding top quality of extruded feed, as well as boost the automation of extruding.
