Author : Browne Donahue | Published On : 17 Feb 2026

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

At the same time, as a result of the mechanical friction between the screw and the material, the product as well as the barrel, and the product inside the product, the product is strongly squeezed, stirred, and sheared, and because of this, the product is further improved and homogenized.

As the pressure slowly boosts, the temperature raises appropriately. When the paste material is ejected from the die opening, under the activity of a strong pressure difference, the material is puffed by floating fish feed making machine, dried out and also cooled. The puffed item is loose, porous, crisp, and also has good palatability and flavor.

The fish feed pellet extruder puffing technology breaks through the typical processing innovation, makes the physical residential properties of the feed change qualitatively, greatly advertises the growth of the feed processing market as well as the reproducing market, and is a major advancement in the feed market.

The fish feed pellet extruder puffing process is a process that integrates different operations such as blending, massaging, shearing, heating, and also cooling. The following is a certain analysis from the aspects of thickness control, automatic control and also energy saving and intake decrease.

1. Thickness control modern technology

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

It is viable to regulate the product density by changing the raw product or formula, but it has little application value; by altering the screw arrangement, the thickness control of the extruded feed item can be realized, yet the operation is inconvenient. feed pellet machine in Kyrgyzstan can likewise be accomplished by changing the operating specifications.

In addition, in the fish feed pellet extruder handling of water feed, in order to meet the feeding requirements of water animals, the ups and also downs of marine feed must be regulated, and also the ups and also downs of feed are closely related to thickness, so density control is used in the production of marine extruded feed.

Technology is especially essential. Today, regulating the thickness of extruded items is mostly accomplished by regulating the pressure as well as temperature level. The primary approaches are as complies with:

( 1 )Open up a stress alleviation opening on the extruding cavity, as well as connect the stress relief opening when creating floating feed, so as to fulfill the needs of high temperature and high pressure for processing floating feed.

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


These products are extruded by fish feed pellet extruder throughout of the extruding tooth cavity and afterwards compacted to get a heavy feed with high bulk thickness. This pressure alleviation hole can additionally be utilized to evacuate, so that the product loses part of the water vapor throughout the forced movement.

This fish feed pellet extruder process technique realizes the control of the density of the extruded product by regulating the pressure in the extruding dental caries, and the outcome will certainly not be influenced because the feeding amount does not need to be minimized.

( 2) A pressure regulating device is added in the floating fish feed extruder machine (pressurization prior to the die). The stress law of the fish feed pellet extruder is to set up a shut-off shutoff between the extrusion dental caries as well as the discharge design template to adjust the stress distinction between the extrusion cavity as well as the outside of the extrusion cavity.

( 2 )Pressure reducing technology (post-mold stress). A new kind of density control system was established for aquafeed. This density control system of fish feed pellet extruder adopts pressurized cutting technology to maintain a certain positive stress in the cutting chamber.

When the product gets in the reducing chamber from the puffing chamber, given that the boiling point of water raises with the stress, the flash evaporation can be decreased to manage the level of development of the material, and also the starch particles are instantly strengthened in the cutting chamber, as well as the product no longer enters the typical stress from the reducing chamber.


The positive stress of the cutting chamber can be recognized by inputting pressed air with an air pump, as well as the fan can be turned off when discharging.

This fish feed pellet extruder process technique stays clear of controlling other elements that influence the level of growth, therefore minimizing the need for hand-operated operation, and also at the same time, the controllability is more powerful than various other approaches.

Today, this brand-new fish feed pellet extruder modern technology has not been applied in China, but this modern technology is superior to the exhaust method in regards to density control of extruded products and also procedure and also use, and also is a new instructions for the development of extruded modern technology.

( 4) Regulating the opening rate of the layout. By altering the opening rate of the discharge layout, the pressure distinction prior to and after the layout can be transformed, so regarding attain the function of managing the density of the product. 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 specific control of the process specifications by outfitting the extrusion equipment with a computer-aided control system.

The application of automatic control modern technology in the fish feed pellet extruder puffing process can not just improve job efficiency, yet additionally enhance product quality security. Models of automated control in your home as well as abroad

There are studies on all sides. The automated control innovation of the fish feed pellet extruder puffing process has actually made excellent progress, and a visualization control system of the puffing process has been established. The extruding system of fish feed pellet extruder based upon repair industrial arrangement software application realizes the visual control of the extruding process

The sensor can be utilized to carry out on-site discovery and also feedback on the operating criteria of the fish feed pellet extruder, instantly change the pertinent working criteria of the floating fish feed pellet machine, as well as realize numerous preset by the driver.

Functioning specifications, with formula storage space, record printing, alarm system, vibrant display and recording of functioning specifications. Foreign computer system automated control technology has already been used in the field of feed handling

In the entire fish feed pellet extruder process, it has been established from a single computer control system to an advanced automated control system, which can present shade images in the main control area, computer program control and communication network for floating fish feed making machine procedure, it can complete all manufacturing treatments without unmanned operation.

As a whole, the automatic control of puffing in feed handling abroad has been creating in the direction of the instructions of integrating with item top quality.

While the introduction of computers in my nation is primarily to fix the trouble of production automation, just concentrating on the surveillance of equipment operation in the manufacturing process and also the control of stand-alone equipment. It has not played its due role in improving product high quality and also various other facets.

3. Energy conserving in extrusion process.

The problem of energy saving and also consumption reduction is the study emphasis in the fish feed pellet extruder extrusion process.

Presently, it is primarily via the study of low power usage processing innovation and also the impact of primary process parameters on power consumption, and also the establishment of matching mathematical designs to achieve the objective of power conserving and usage reduction.

In order to decrease the power consumption in the fish feed pellet extruder puffing process, some residential feed suppliers generally take measures from the process. For instance, in the manufacturing process of suckling pig feed, the corn raw material made use of is not complete puffed product, however part of the puffed material and also part of the traditional product.

In the later fish feed pellet extruder granulation process, processes such as expansion and also reduced temperature level granulation are utilized to make sure that the power intake per unit item is minimized.

From the above analysis, it can be seen that it is still a traffic jam problem how the process specification research study in the fish feed pellet extruder puffing process can be personified in minimizing power usage and also can be understood in real production.

4. Application of extrusion in floating fish feed processing.

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

( 1 )The processing temperature level is high and also the dampness web content is huge, and the product can be totally grown and broken down. The pellets are of high quality as well as the feed titer is high;
( 2 )The flexible variety of pellet density is large, which can adjust to the demands of various feeding items and also different feeding environments.

( 1) Puffed suckling pig feed

The vital indications of nursing pig feed are hygiene as well as maturation to stop suckling pigs from diarrhea. The raw materials are treated with high temperature and high pressure, on the one hand, it kills pathogenic germs, on the other hand, the starch material is completely cooked, as well as the soybean healthy protein is denatured as well as cleansed, so that the material is simple to digest and also soak up. Gelatinized starch can promote the production of lactic acid in animals and also boost the anti-bacterial ability of animals.

( 2) Extruded water feed
The water feedl is extruded as well as granulated by fish feed pellet extruder, which enhances the top quality of the product from all elements.

① Improved feed titer. Extrusion ripens the starch, which is essential for fish as raw starch is challenging to absorb. The starch is prepared, the cohesiveness of the product is boosted, and the creating effect is excellent. On the facility of making sure the top quality of pellets, the formula can be gotten used to decrease expenses.

② The floating time of pellets in water is managed by the density of pellets, as well as the density is figured out by the level of puffing by fish feed pellet extruder.

For that reason, by changing the formula, changing the range and content of starch and binder, and also changing the process parameters, that is, adjusting the dampness, stress, temperature, and so on, extruded pellets with various thickness can be created.

( 3) Puffed chicken feed

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

Experiments have shown that puffing can enhance the food digestion and absorption price of feed for poultries. Extruded chicken feed, as a result of its little mass density, can lower chicken feed consumption, prevent excessive weight, as well as boost egg production.

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

Ruminants such as cattle as well as sheep can transform non-protein nitrogen (such as urea) into animal healthy protein. The trick to including urea to feed is how to control the addition quantity, uniform feed intake as well as urea disintegration rate. Urea-expanded corn addresses these troubles most effectively.

The urea, corn flour and also additives are mixed in a particular percentage and then get in the floating pellet machine, the corn flour is expanded, and the gelatinized starch and urea develop a finishing structure. Urease inhibitors prevent the activity of urease. It inhibits the release rate of ammonia after urea disintegration from two elements, as well as avoids ammonia poisoning triggered by excess ammonia.

( 5) Rice bran preservation therapy.

Fresh rice bran contains extremely energetic lipolytic enzymes, which can rapidly break down the oil included in rice bran right into complimentary lipids.

Fat and rancidity, so the storage space performance of fresh rice bran is very bad. The rancid as well as ruined rice bran not just lowers the oil yield, but additionally influences the growth and also advancement of animals and poultry if fed as feed.

Therefore, fresh rice bran need to be maintained fresh in time. Extrusion, high temperature, high pressure and also high shear can inactivate lipase as well as prevent rancidity and also damage. Extrusion has actually become a brand-new pretreatment process in rice bran oil manufacturing.

( 6) Detoxing of oilseed dish healthy protein.

In addition to soybean cake (dish), the cake (meal) acquired from rapeseed, cottonseed, sunflower seed, castor and also various other oilseeds also consists of a specific quantity of healthy protein, which is an excellent source of feed healthy protein. Nonetheless, various oil cakes (consisting of soybean meal) can not be directly utilized to formulate feed, because they all include a certain quantity of anti-nutritional elements or various other harmful elements.

Oil cake (meal) have to be purified prior to it can be made use of. Cleansing techniques consist of chemical as well as physical approaches. Oilseed cake (dish) extrusion detoxification is a contemporary innovation related to oil cake (meal) treatment by extrusion modern technology.

( 7) Feather puffing processing.

Because of the existence of disulfide bonds as well as hydrogen bonds in between feather polypeptide chains, the structure of feather protein is particularly secure, and pet gastrointestinal enzymes are basically not able to absorb as well as decompose, so the plume extrusion technology has been established.

After the feather is extruded and also puffed, its disulfide bond is broken, the molecular framework is damaged, and the digestive enzyme is simple to digest and decompose, and also the digestibility is enhanced. The digestibility is associated with the degree of destruction as well as extrusion temperature.

When the floating pellet machine extrusion temperature level is high, the digestibility of the puffed plume product rises, but the amino acid content of the item lowers similarly, as well as the protein quality of the product decreases.

Feather dish has high protein web content, but the amino acid is not balanced sufficient. In order to solve this issue, poultry viscera, poultry blood and also plumes can be combined as well as processed right into digestive plume dish.


Fish feed pellet extruder extruding innovation is a feed processing modern technology established at the end of the 20th century. Pressure cutting has a great impact on controlling the thickness of extruded items, giving a new approach for handling high-demand aquafeeds.

Making use of waste vapor and also waste warm for conditioning makes the machine a lot more eco-friendly and also adapts to the pattern of the times. Extrusion modern technology of fish feed pellet extruder is commonly utilized in marine, swine as well as ruminant feeds, which has a considerable result on altering feed top quality and decreasing expenses.

With the advancement of fish feed pellet extruder extruding technology, more in-depth research study is required on how to properly regulate the expansiveness as well as extruding top quality of extruded feed, and improve the automation of extruding.
