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

At the same time, due to the mechanical rubbing in between the screw and the material, the product and also the barrel, and also the material inside the product, the material is highly squeezed, stirred, as well as sheared, and consequently, the product is further fine-tuned as well as co-opted.

As the pressure gradually raises, the temperature level enhances as necessary. When the paste product is ejected from the die opening, under the action of a strong stress difference, the material is puffed by floating fish feed making machine, dehydrated as well as cooled down. The puffed product is loose, permeable, crisp, and has great palatability as well as flavor.

The fish feed pellet extruder puffing innovation breaks through the traditional processing technology, makes the physical buildings of the feed change qualitatively, significantly promotes the growth of the feed handling market as well as the reproducing sector, and also is a major innovation in the feed industry.

The fish feed pellet extruder puffing process is a process that incorporates various operations such as mixing, kneading, shearing, home heating, and cooling. The following is a certain evaluation from the aspects of thickness control, automatic control and power saving and also usage reduction.

1. Thickness control modern technology

In the extrusion process of fish feed pellet extruder, there are many factors that affect the thickness of feed, such as refining modern technology, fish feed pellet extruder equipment, processing criteria, process control, feed basic materials, formula and so forth.

It is viable to control the product density by transforming the raw product or formula, but it has little application value; by altering the screw setup, the thickness control of the extruded feed product can be recognized, but the operation is troublesome. Thickness control can likewise be accomplished by adjusting the operating specifications.

Additionally, in the fish feed pellet extruder handling of water feed, in order to meet the feeding needs of water animals, the ups and also downs of aquatic feed must be regulated, and the ups and downs of feed are closely related to thickness, so thickness control is applied in the production of aquatic extruded feed.

Innovation is especially vital. Currently, controlling the density of extruded items is generally achieved by regulating the pressure and also temperature. The main techniques are as complies with:

( 1 )Open up a pressure relief hole on the extruding cavity, and also connect the pressure relief hole when generating floating feed, so as to meet the needs of heat as well as high pressure for handling floating feed.

Open the pressure relief hole when feeding, so that when the product gets to the pressure relief hole, the pressure in the sleeve is partly released, and also at the same time, some water vapor is also released from the pressure alleviation hole.


These materials are extruded by fish feed pellet extruder throughout of the extruding cavity and afterwards compacted to obtain a hefty feed with high bulk density. This stress relief opening can also be utilized to evacuate, so 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 density of the extruded product by managing the stress in the extruding cavity, and also the outcome will certainly not be influenced because the feeding amount does not require to be reduced.

( 2) A pressure controling gadget is added in the floating fish feed extruder machine (pressurization prior to the die). The stress policy of the fish feed pellet extruder is to mount a shut-off valve between the extrusion dental caries as well as the discharge design template to adjust the stress difference between the extrusion tooth cavity and the outside of the extrusion cavity.

( 2 )Pressure reducing innovation (post-mold stress). A brand-new type of density control system was created for aquafeed. This density control system of fish feed pellet extruder adopts pressurized reducing technology to maintain a specific favorable stress in the reducing chamber.

When the product gets in the reducing chamber from the puffing chamber, because the boiling point of water increases with the stress, the flash evaporation can be reduced to control the degree of growth of the material, as well as the starch molecules are instantaneously strengthened in the cutting chamber, and also the material no more enters the normal pressure from the cutting chamber.

The favorable pressure of the cutting chamber can be recognized by inputting compressed air with an air pump, and the follower can be switched off when releasing.

This fish feed pellet extruder process method prevents controlling various other variables that impact the level of growth, thereby minimizing the requirement for hands-on procedure, as well as at the same time, the controllability is stronger than various other methods.

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

( 4) Managing the opening price of the design template. By altering the opening price of the discharge template, the pressure difference prior to and also after the theme can be transformed, so regarding accomplish the function of controlling the thickness 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 describes the quick and also specific control of the process criteria by furnishing 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 improve job efficiency, but likewise enhance item top quality stability. Models of automated control at home and abroad

There are studies on all sides. The automatic control innovation of the fish feed pellet extruder puffing process has actually made terrific progress, as well as a visualization control system of the puffing process has been developed. The extruding system of fish feed pellet extruder based upon repair industrial configuration software application understands the visual control of the extruding process

The sensor can be made use of to carry out on-site discovery and also responses on the operating specifications of the fish feed pellet extruder, immediately adjust the relevant working specifications of the floating fish feed pellet machine, and also realize different preset by the driver.

Working criteria, with formula storage, record printing, alarm system, vibrant display and recording of functioning specifications. Foreign computer automatic control innovation has already been applied in the field of feed processing

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

Generally, the automatic control of puffing in feed handling abroad has actually been developing towards the instructions of integrating with product high quality.

While the introduction of computer systems in my nation is primarily to resolve the problem of production automation, just focusing on the tracking 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 boosting product high quality and also various other elements.

3. Energy conserving in extrusion process.

The issue of power conserving as well as usage reduction is the study focus in the fish feed pellet extruder extrusion process.

At present, it is mainly through the research of reduced energy intake handling innovation and also the influence of primary process specifications on energy consumption, as well as the establishment of matching mathematical models to achieve the purpose of power conserving as well as consumption reduction.

In order to minimize the energy intake in the fish feed pellet extruder puffing process, some residential feed makers generally take measures from the process. For instance, in the manufacturing process of suckling pig feed, the corn raw material used is not complete puffed product, yet part of the puffed material and part of the traditional product.

In the later fish feed pellet extruder granulation process, processes such as expansion as well as reduced temperature granulation are utilized 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 bottleneck trouble just how the process parameter research in the fish feed pellet extruder puffing process can be embodied in reducing power intake and can be realized in actual production.

4. Application of extrusion in floating fish feed handling.

In the last few years, the application of fish feed pellet extruder extrusion innovation to feed manufacturing is an epoch-making jump in feed manufacturing technology. The primary benefits of extruded granulation:

( 1 )The handling temperature is high as well as the moisture content is large, and the material can be completely grown and broken down. The pellets are of high quality and also the feed titer is high;
( 2 )The adjustable variety of pellet thickness is huge, which can adapt to the requirements of various feeding objects as well as various feeding atmospheres.


( 1) Puffed suckling pig feed

The essential indicators of suckling pig feed are hygiene as well as growth to avoid suckling pigs from diarrhea. The raw materials are treated with high temperature as well as high pressure, on the one hand, it kills pathogenic germs, on the other hand, the starch material is fully cooked, as well as the soybean protein is denatured and also detoxed, to ensure that the material is very easy to digest and also take in. Gelatinized starch can boost the manufacturing of lactic acid in animals as well as enhance the anti-bacterial ability of pets.

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

① Improved feed titer. Extrusion ripens the starch, which is necessary for fish as raw starch is challenging to digest. The starch is cooked, the cohesiveness of the product is enhanced, and also the creating impact is excellent. On the facility of making certain the top quality of pellets, the formula can be adapted to reduce expenses.

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

Therefore, by readjusting the formula, adjusting the variety and web content of starch and binder, and changing the process criteria, that is, adjusting the moisture, stress, temperature level, etc, extruded pellets with various densities can be created.

( 3) Puffed chicken feed

The formula of chicken feed includes high starch material and also 15% -20% healthy protein product at the same time. For this percentage, no matter the dry floating pellet machine or the damp floating pellet machine, the technological efficiency is much better.

Experiments have shown that puffing can boost the food digestion as well as absorption rate of feed for poultries. Extruded chicken feed, as a result of its tiny bulk thickness, can lower chicken feed intake, avoid excessive weight, as well as boost egg manufacturing.

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

pellet machine in Kiribati 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 exactly how to regulate the addition amount, consistent feed consumption and urea decay price. Urea-expanded corn resolves these issues most properly.

The urea, corn flour and ingredients are mixed in a particular proportion and after that go into the floating pellet machine, the corn flour is broadened, as well as the gelatinized starch and also urea form a layer framework. Urease inhibitors prevent the activity of urease. It hinders the launch price of ammonia after urea disintegration from 2 elements, as well as stays clear of ammonia poisoning brought on by excess ammonia.

( 5) Rice bran conservation treatment.

Fresh rice bran contains extremely active lipolytic enzymes, which can rapidly decay the oil included in rice bran right into totally free lipids.

Fatty acid and also rancidity, so the storage space efficiency of fresh rice bran is very bad. The rancid and also spoiled rice bran not only lowers the oil yield, but likewise affects the development and development of livestock and poultry if fed as feed.

Consequently, fresh rice bran need to be kept fresh in time. Extrusion, heat, high pressure and also high shear can suspend lipase and also prevent rancidity and also wear and tear. Extrusion has ended up being a new pretreatment process in rice bran oil production.

( 6) Detoxification of oilseed meal healthy protein.

Along with soybean cake (meal), the cake (dish) acquired from rapeseed, cottonseed, sunflower seed, castor as well as various other oilseeds also consists of a particular quantity of healthy protein, which is a superb source of feed healthy protein. However, different oil cakes (consisting of soybean dish) can not be straight utilized to create feed, because they all have a certain amount of anti-nutritional aspects or various other hazardous elements.

Oil cake (meal) need to be purified prior to it can be utilized. Detoxification approaches consist of chemical as well as physical methods. Oilseed cake (dish) extrusion cleansing is a contemporary technology put on oil cake (dish) treatment by extrusion innovation.

( 7) Plume puffing handling.

Due to the existence of disulfide bonds as well as hydrogen bonds between feather polypeptide chains, the framework of feather healthy protein is especially stable, and pet digestive system enzymes are basically unable to absorb as well as decay, so the plume extrusion technology has been developed.

After the plume is extruded and puffed, its disulfide bond is broken, the molecular framework is damaged, and the digestive system enzyme is simple to digest and also disintegrate, and the digestibility is boosted. The digestibility is connected to the level of destruction as well as extrusion temperature.

When the floating pellet machine extrusion temperature level is high, the digestibility of the puffed feather product rises, but the amino acid web content of the product decreases likewise, and also the healthy protein top quality of the product reduces.

Plume meal has high protein material, yet the amino acid is not stabilized enough. In order to address this issue, hen viscera, chicken blood as well as plumes can be mixed and also refined into digestive tract plume dish.


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

The use of waste heavy steam and also waste warm for conditioning makes the machine extra environmentally friendly and adapts to the trend of the times. Extrusion technology of fish feed pellet extruder is extensively utilized in water, swine as well as ruminant feeds, which has a significant impact on changing feed quality and decreasing expenses.

With the growth of fish feed pellet extruder extruding technology, even more comprehensive research is required on exactly how to accurately regulate the expansiveness and also extruding high quality of extruded feed, and also improve the automation of extruding.
