Author : Browne Donahue | Published On : 10 Apr 2026

In the production of extruded feed, the major equipment is a screw fish feed pellet extruder. The material is fed into the fish feed pellet extruder, and also the screw screw pushes the product to create an axial flow.

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

As the pressure progressively raises, the temperature boosts accordingly. When the paste material is expelled from the die opening, under the action of a solid stress distinction, the product is puffed by floating fish feed making machine, dehydrated and also cooled down. you can find out more puffed product hangs, porous, crisp, and also has excellent palatability and flavor.

The fish feed pellet extruder puffing innovation appear the conventional processing modern technology, makes the physical residential or commercial properties of the feed adjustment qualitatively, substantially promotes the advancement of the feed handling market as well as the reproducing industry, and is a significant innovation in the feed market.

The fish feed pellet extruder puffing process is a process that integrates different operations such as blending, working, shearing, home heating, and air conditioning. The following is a particular evaluation from the aspects of density control, automated control and power saving and also consumption decrease.

1. Thickness control modern technology

In the extrusion process of fish feed pellet extruder, there are several variables that affect the density of feed, such as refining innovation, fish feed pellet extruder equipment, refining specifications, process control, feed raw materials, formula and more.

It is possible to manage the product density by transforming the raw material or formula, however it has little application worth; by changing the screw configuration, the density control of the extruded feed item can be realized, but the operation is inconvenient. Thickness control can also be attained by adjusting the operating criteria.

Furthermore, in the fish feed pellet extruder handling of aquatic feed, in order to meet the feeding demands of water pets, the ups and also downs of aquatic feed should be controlled, and the ups and also downs of feed are carefully pertaining to density, so density control is used in the manufacturing of marine extruded feed.

Modern technology is especially essential. Currently, regulating the density of extruded products is mostly attained by controlling the stress as well as temperature level. The major techniques are as adheres to:

( 1 )Open a stress relief hole on the extruding cavity, and also plug the stress alleviation opening when creating floating feed, so regarding satisfy the needs of high temperature and also high pressure for processing floating feed.

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


These materials are extruded by fish feed pellet extruder to the end of the extruding dental caries and after that compressed to acquire a hefty feed with high bulk density. This stress alleviation opening can also be utilized to evacuate, to make sure that the material sheds part of the water vapor throughout the forced motion.

This fish feed pellet extruder process technique realizes the control of the thickness of the extruded product by regulating the stress in the extruding tooth cavity, as well as the output will certainly not be affected due to the fact that the feeding amount does not need to be minimized.

( 2) A pressure regulating gadget is included the floating fish feed extruder machine (pressurization prior to the die). pellet mill in Costa Rica of the fish feed pellet extruder is to set up a shut-off shutoff between the extrusion dental caries and also the discharge theme to readjust the pressure difference in between the extrusion tooth cavity and the outside of the extrusion dental caries.

( 2 )Pressure reducing technology (post-mold pressure). A brand-new kind of density control system was established for aquafeed. This thickness control system of fish feed pellet extruder embraces pressurized reducing innovation to maintain a specific positive pressure in the reducing chamber.

When the product enters the cutting chamber from the puffing chamber, since the boiling point of water increases with the pressure, the flash dissipation can be lowered to control the degree of development of the material, and the starch particles are promptly strengthened in the cutting chamber, and also the material no more enters the typical pressure from the cutting chamber.

The favorable stress of the reducing chamber can be recognized by inputting compressed air with an air pump, and also the fan can be switched off when releasing.

This fish feed pellet extruder process technique stays clear of controlling other elements that influence the level of growth, therefore lowering the need for hands-on procedure, and at the same time, the controllability is stronger than other approaches.

Presently, this brand-new fish feed pellet extruder modern technology has actually not been used in China, however this innovation transcends to the exhaust method in regards to density control of extruded products and also operation and use, and is a brand-new instructions for the growth of extruded innovation.

( 4) Controlling the opening price of the template. By transforming the opening price of the discharge design template, the pressure distinction prior to and also after the design template can be changed, 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 automatic control of the fish feed pellet extruder extrusion process refers to the rapid and also exact control of the process criteria by equipping the extrusion equipment with a computer-aided control system.

The application of automated control innovation in the fish feed pellet extruder puffing process can not only boost work effectiveness, but likewise enhance product high quality security. Models of automatic control at home as well as abroad

There are researches on all sides. The automatic control modern technology of the fish feed pellet extruder puffing process has made terrific progress, and also a visualization control system of the puffing process has been created. The extruding system of fish feed pellet extruder based on solution industrial configuration software application understands the visual control of the extruding process

The sensing unit can be utilized to conduct on-site discovery and responses on the operating parameters of the fish feed pellet extruder, instantly change the pertinent functioning specifications of the floating fish feed pellet machine, as well as understand various predetermined by the driver.

Working criteria, with formula storage space, report printing, alarm system, dynamic display and also recording of functioning specifications. Foreign computer system automated control technology has already been used in the field of feed processing

In the entire fish feed pellet extruder process, it has been established from a solitary computer control system to an advanced automated control system, which can display shade images in the main control space, computer program control and interaction network for floating fish feed making machine operation, it can finish all manufacturing procedures without unmanned operation.

As a whole, the automated control of puffing in feed handling abroad has actually been developing towards the direction of integrating with product high quality.

While the introduction of computer systems in my nation is generally to fix the problem of manufacturing automation, only concentrating on the monitoring of equipment procedure in the production process as well as the control of stand-alone equipment. It has actually not played its due function in enhancing product quality as well as various other facets.

3. Power saving in extrusion process.

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

Currently, it is generally with the study of low energy usage processing technology and the influence of primary process criteria on power intake, as well as the establishment of matching mathematical versions to achieve the objective of energy conserving and also usage decrease.

In order to minimize the power consumption in the fish feed pellet extruder puffing process, some domestic feed suppliers mainly take measures from the process. For instance, in the production process of nursing pig feed, the corn resources utilized is not full puffed product, yet part of the puffed product and part of the traditional material.

In the later fish feed pellet extruder granulation process, processes such as growth and low temperature granulation are utilized to make certain that the energy intake each product is minimized.

From the above evaluation, it can be seen that it is still a traffic jam trouble how the process criterion study in the fish feed pellet extruder puffing process can be symbolized in lowering power intake and also can be realized in actual production.

4. Application of extrusion in floating fish feed processing.

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

( 1 )The processing temperature is high as well as the dampness web content is large, and also the product can be completely matured and broken down. The pellets are of top quality and also the feed titer is high;
( 2 )The adjustable series of pellet density is big, which can adapt to the requirements of different feeding items and different feeding atmospheres.

( 1) Puffed suckling pig feed

The crucial signs of suckling pig feed are health and growth to stop suckling pigs from diarrhea. The raw materials are treated with high temperature and also high pressure, on the one hand, it kills pathogenic germs, on the other hand, the starch material is totally cooked, and also the soybean protein is denatured and also purified, to ensure that the product is very easy to absorb and also soak up. Gelatinized starch can stimulate the manufacturing of lactic acid in animals as well as boost the antibacterial capability of animals.

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

① Improved feed titer. Extrusion ripens the starch, which is essential for fish as raw starch is challenging to digest. The starch is prepared, the cohesiveness of the product is boosted, and also the forming result is great. On the property of making sure the high quality of pellets, the formula can be adapted to lower costs.

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

As a result, by readjusting the formula, adjusting the variety and material of starch and also binder, as well as changing the process parameters, that is, adjusting the wetness, stress, temperature level, etc, extruded pellets with various densities can be produced.

( 3) Puffed chicken feed

The formula of chicken feed has high starch product as well as 15% -20% protein product at the same time. For this proportion, despite the dry floating pellet machine or the damp floating pellet machine, the technical efficiency is better.

Experiments have actually revealed that puffing can boost the digestion and also absorption price of feed for chickens. Extruded chicken feed, because of its little mass thickness, can minimize chicken feed consumption, prevent weight problems, and also boost egg production.

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

Ruminants such as livestock as well as lamb can convert non-protein nitrogen (such as urea) into pet healthy protein. The key to including urea to feed is just how to regulate the enhancement amount, consistent feed consumption and also urea decay price. Urea-expanded corn resolves these issues most successfully.

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 increased, and the gelatinized starch and also urea develop a finish structure. Urease preventions hinder the activity of urease. It hinders the release rate of ammonia after urea decomposition from 2 elements, and prevents ammonia poisoning brought on by excess ammonia.

( 5) Rice bran conservation treatment.

Fresh rice bran contains very energetic lipolytic enzymes, which can rapidly decompose the oil contained in rice bran into free lipids.

Fat as well as rancidity, so the storage space efficiency of fresh rice bran is extremely poor. The rancid and also ruined rice bran not just lowers the oil return, however also impacts the development and also advancement of livestock 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 and also stop rancidity and wear and tear. Extrusion has actually become a brand-new pretreatment process in rice bran oil production.

( 6) Cleansing of oilseed dish protein.

Along with soybean cake (dish), the cake (dish) gotten from rapeseed, cottonseed, sunflower seed, castor as well as various other oilseeds likewise contains a certain amount of healthy protein, which is a superb resource of feed healthy protein. However, different oil cakes (including soybean dish) can not be directly utilized to create feed, since they all have a specific amount of anti-nutritional elements or various other harmful parts.


Oil cake (meal) must be purified prior to it can be utilized. Cleansing methods include chemical as well as physical approaches. Oilseed cake (meal) extrusion detoxification is a modern technology applied to oil cake (dish) treatment by extrusion technology.

( 7) Plume puffing processing.

Due to the presence of disulfide bonds and also hydrogen bonds in between feather polypeptide chains, the structure of feather protein is especially stable, as well as pet digestive enzymes are generally not able to absorb and disintegrate, so the plume extrusion modern technology has actually been developed.

After feed pellet machine in Kenya is extruded as well as puffed, its disulfide bond is damaged, the molecular structure is damaged, and also the gastrointestinal enzyme is simple to absorb and also decompose, and also the digestibility is enhanced. The digestibility is associated with the degree of deterioration as well as extrusion temperature.

When the floating pellet machine extrusion temperature level is high, the digestibility of the puffed plume product boosts, however the amino acid content of the item reduces likewise, as well as the protein high quality of the item decreases.

Feather dish has high protein material, yet the amino acid is not stabilized enough. In order to address this trouble, hen viscera, poultry blood as well as plumes can be blended and also refined right into digestive tract feather meal.


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

The use of waste steam and 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 widely used in water, swine as well as ruminant feeds, which has a substantial result on transforming feed quality as well as lowering prices.

With the development of fish feed pellet extruder extruding modern technology, even more extensive research study is needed on exactly how to precisely manage the expansiveness and also extruding high quality of extruded feed, and improve the automation of extruding.
