In the production 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 also the screw screw pushes the product to create an axial circulation.

At the same time, because of the mechanical rubbing in between the screw and the material, the material as well as the barrel, and the product inside the material, the material is strongly squeezed, mixed, and sheared, and also because of this, the material is additional fine-tuned as well as homogenized.

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

The fish feed pellet extruder puffing innovation breaks through the standard processing technology, makes the physical properties of the feed change qualitatively, substantially promotes the growth of the feed processing industry and the reproducing market, and also is a significant technology in the feed industry.

The fish feed pellet extruder puffing process is a process that integrates numerous operations such as blending, working, shearing, heating, and also cooling. The following is a particular evaluation from the elements of density control, automated control as well as energy conserving and intake decrease.

1. Thickness control technology

In the extrusion process of fish feed pellet extruder, there are many factors that impact the thickness of feed, such as processing modern technology, fish feed pellet extruder equipment, processing parameters, process control, feed raw materials, formula and so on.

It is feasible to control the product thickness by transforming the raw product or formula, but it has little application value; by transforming the screw setup, the thickness control of the extruded feed item can be recognized, but the operation is troublesome. Thickness control can additionally be achieved by adjusting the operating specifications.

In addition, in the fish feed pellet extruder processing of aquatic feed, in order to satisfy the feeding requirements of water pets, the ups as well as downs of water feed ought to be regulated, and the ups and also downs of feed are carefully pertaining to density, so thickness control is applied in the production of aquatic extruded feed.

Modern technology is specifically vital. Currently, controlling the thickness of extruded products is mainly achieved by managing the pressure and temperature level. The major techniques are as follows:

( 1 )Open up a stress alleviation opening on the extruding dental caries, and connect the pressure relief opening when producing floating feed, so regarding fulfill the requirements of heat and also high pressure for processing floating feed.

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


These materials are extruded by fish feed pellet extruder to the end of the extruding tooth cavity and after that compacted to obtain a heavy feed with high mass thickness. This stress relief opening can also be utilized to evacuate, to ensure that the product sheds part of the water vapor during the forced activity.

pellet machine in Marshall Islands realizes the control of the thickness of the extruded item by regulating the stress in the extruding dental caries, as well as the result will certainly not be influenced because the feeding amount does not require to be decreased.

( 2) A pressure controling device is added in the floating fish feed extruder machine (pressurization before the die). The pressure law of the fish feed pellet extruder is to set up a shut-off shutoff in between the extrusion cavity as well as the discharge theme to readjust the stress distinction between the extrusion cavity as well as the outside of the extrusion tooth cavity.

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

When the product enters the reducing chamber from the puffing chamber, given that the boiling point of water increases with the pressure, the flash evaporation can be decreased to control the degree of development of the product, as well as the starch particles are instantly solidified in the cutting chamber, and also the material no longer gets in the normal stress 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 follower can be turned off when releasing.

This fish feed pellet extruder process method prevents controlling various other aspects that affect the level of growth, consequently lowering the requirement for hand-operated procedure, as well as at the same time, the controllability is stronger than other techniques.

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

( 4) Managing the opening price of the theme. By transforming the opening rate of the discharge theme, the stress difference prior to as well as after the layout can be transformed, so as to accomplish the purpose of managing the thickness of the product. The hole is obstructed.

2. Automatic control of fish feed extrusion process

The automatic control of the fish feed pellet extruder extrusion process describes the fast and exact control of the process criteria by outfitting 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 performance, however additionally improve product high quality stability. Models of automatic 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 made wonderful progress, and also a visualization control system of the puffing process has actually been created. The extruding system of fish feed pellet extruder based on repair industrial arrangement software application recognizes the visual control of the extruding process

The sensor can be utilized to conduct on-site detection as well as feedback on the operating criteria of the fish feed pellet extruder, instantly adjust the relevant working specifications of the floating fish feed pellet machine, as well as realize various preset by the operator.

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

In the whole fish feed pellet extruder process, it has been created from a solitary computer control system to a sophisticated automated control system, which can present color images in the main control area, computer system program control and also interaction network for floating fish feed making machine procedure, it can complete all manufacturing procedures without unmanned operation.

Generally, the automatic control of puffing in feed handling abroad has been establishing towards the direction of incorporating with item top quality.

While the introduction of computer systems in my nation is mostly to address the problem of production automation, just focusing on the monitoring of equipment operation in the production process and the control of stand-alone equipment. It has not played its due role in enhancing item quality and also other aspects.

3. Energy conserving in extrusion process.

The issue of power saving as well as usage reduction is the research study emphasis in the fish feed pellet extruder extrusion process.

At present, it is mainly with the study of low energy usage processing innovation and the impact of primary process parameters on power consumption, as well as the establishment of matching mathematical versions to attain the objective of energy saving and also usage reduction.

In order to lower the energy intake in the fish feed pellet extruder puffing process, some domestic feed manufacturers primarily take measures from the process. For instance, in the manufacturing process of suckling pig feed, the corn resources made use of is not complete puffed product, however part of the puffed product as well as part of the traditional product.

In the later fish feed pellet extruder granulation process, processes such as development and reduced temperature granulation are made use of to make certain that the energy intake per unit item is minimized.

From the above evaluation, it can be seen that it is still a traffic jam trouble how the process parameter research study in the fish feed pellet extruder puffing process can be personified in minimizing energy usage and also can be recognized in real production.

4. Application of extrusion in floating fish feed handling.

In recent years, the application of fish feed pellet extruder extrusion innovation to feed production is an epoch-making jump in feed production innovation. The primary advantages of extruded granulation:

( 1 )The handling temperature is high as well as the dampness content is large, and also the material can be totally developed and deteriorated. The pellets are of good quality and the feed titer is high;
( 2 )The flexible series of pellet thickness is huge, which can adapt to the demands of numerous feeding items as well as different feeding environments.


( 1) Puffed suckling pig feed

The vital indications of suckling pig feed are health as well as growth to stop suckling pigs from diarrhea. The raw products 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 the soybean protein is denatured as well as detoxed, so that the material is easy to absorb and also absorb. Gelatinized starch can stimulate the production of lactic acid in pets and also enhance the anti-bacterial ability of pets.

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

① Boosted feed titer. Extrusion ripens the starch, which is important for fish as raw starch is challenging to absorb. The starch is prepared, the cohesiveness of the material is boosted, as well as the creating effect is great. On the property of making sure the high quality of pellets, the formula can be adjusted to decrease costs.

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

For that reason, by adjusting the formula, adjusting the selection as well as content of starch and binder, and adjusting the process parameters, that is, readjusting the dampness, stress, temperature, and so on, extruded pellets with different densities can be generated.

( 3) Puffed chicken feed

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

Experiments have revealed that puffing can enhance the digestion and absorption rate of feed for hens. Extruded chicken feed, because of its tiny mass density, can decrease chicken feed intake, prevent weight problems, and enhance egg production.

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

Ruminants such as cattle and also lamb can transform non-protein nitrogen (such as urea) into pet healthy protein. The secret to including urea to feed is how to regulate the addition quantity, consistent feed intake and also urea disintegration rate. Urea-expanded corn resolves these problems most effectively.

The urea, corn flour and ingredients are mixed in a particular percentage and afterwards enter the floating pellet machine, the corn flour is increased, and also the gelatinized starch and urea create a finish framework. Urease preventions inhibit the activity of urease. It inhibits the release price of ammonia after urea decomposition from 2 aspects, and also avoids ammonia poisoning brought on by excess ammonia.

( 5) Rice bran conservation therapy.

Fresh rice bran includes extremely energetic lipolytic enzymes, which can quickly break down the oil contained in rice bran into totally free lipids.

Fat and rancidity, so the storage performance of fresh rice bran is incredibly bad. The rancid and also ruined rice bran not only decreases the oil return, yet additionally influences the development and advancement of animals and also chicken if fed as feed.

Therefore, fresh rice bran should be kept fresh in time. Extrusion, heat, high pressure and high shear can suspend lipase and stop rancidity and also wear and tear. Extrusion has come to be a brand-new pretreatment process in rice bran oil production.

( 6) Detoxing of oilseed meal healthy protein.

Along with soybean cake (dish), the cake (meal) obtained from rapeseed, cottonseed, sunflower seed, castor and other oilseeds also has a certain quantity of protein, which is an excellent source of feed protein. Nevertheless, different oil cakes (consisting of soybean dish) can not be directly used to formulate feed, since they all have a specific amount of anti-nutritional aspects or various other unsafe components.

Oil cake (meal) have to be cleansed before it can be utilized. Detoxification techniques consist of chemical and physical approaches. Oilseed cake (dish) extrusion detoxing is a contemporary innovation related to oil cake (dish) treatment by extrusion innovation.

( 7) Feather puffing processing.

Due to the presence of disulfide bonds and also hydrogen bonds between plume polypeptide chains, the framework of plume healthy protein is particularly steady, as well as animal gastrointestinal enzymes are essentially unable to absorb and disintegrate, so the feather extrusion technology has been established.

After the plume is extruded and puffed, its disulfide bond is damaged, the molecular framework is damaged, and the digestion enzyme is easy to digest and also decompose, and also the digestibility is boosted. The digestibility is related to the level of degradation and extrusion temperature.

When the floating pellet machine extrusion temperature is high, the digestibility of the puffed feather item increases, but the amino acid material of the product decreases alike, and the healthy protein quality of the item reduces.

Feather meal has high protein web content, however the amino acid is not balanced enough. In order to fix this problem, poultry viscera, hen blood and also plumes can be combined and processed into intestinal plume dish.


Fish feed pellet extruder extruding innovation is a feed handling modern technology developed at the end of the 20th century. Stress cutting has a good result on managing the density of extruded products, providing a brand-new method for handling high-demand aquafeeds.

Using waste heavy steam as well as waste heat for conditioning makes the machine more eco-friendly as well as adapts to the pattern of the moments. Extrusion technology of fish feed pellet extruder is commonly used in marine, swine and ruminant feeds, which has a substantial result on altering feed high quality as well as reducing expenses.

With the development of fish feed pellet extruder extruding technology, more thorough research study is needed on exactly how to properly control the expansiveness and extruding top quality of extruded feed, and enhance the automation of extruding.
