Floating fish feed pellet extruder technology
In the manufacturing 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 the screw screw pushes the product to form an axial flow.

At the same time, as a result of the mechanical rubbing between the screw and also the product, the material and the barrel, as well as the material inside the product, the product is highly squeezed, mixed, and also sheared, and consequently, the material is further refined and homogenized.

As the pressure progressively boosts, the temperature increases as necessary. When the paste material is ejected from the die hole, under the action of a solid pressure distinction, the product is puffed by floating fish feed making machine, dried out and also cooled down. The puffed item hangs, permeable, crisp, as well as has great palatability and also flavor.

The fish feed pellet extruder puffing technology breaks through the typical handling modern technology, makes the physical residential or commercial properties of the feed modification qualitatively, considerably promotes the development of the feed handling industry as well as the reproducing industry, as well as is a significant technology in the feed market.

The fish feed pellet extruder puffing process is a process that integrates numerous procedures such as blending, kneading, shearing, heating, and cooling. The following is a particular evaluation from the elements of thickness control, automated control and also energy conserving and also consumption decrease.

1. Thickness control innovation

In the extrusion process of fish feed pellet extruder, there are many factors that affect the density of feed, such as processing technology, fish feed pellet extruder equipment, processing parameters, process control, feed resources, formula and so forth.

best pellet mill supplier 2026 is possible to control the product density by altering the raw material or formula, yet it has little application worth; by transforming the screw setup, the density control of the extruded feed item can be understood, yet the procedure is inconvenient. Density control can additionally be achieved by adjusting the operating parameters.

Additionally, in the fish feed pellet extruder handling of marine feed, in order to meet the feeding demands of water pets, the ups and downs of aquatic feed need to be controlled, and also the ups and also downs of feed are very closely related to thickness, so density control is used in the manufacturing of aquatic extruded feed.

Technology is specifically important. Today, regulating the thickness of extruded products is primarily achieved by managing the pressure as well as temperature. The main methods are as complies with:

( 1 )Open a pressure relief opening on the extruding dental caries, and connect the stress alleviation hole when creating floating feed, so as to satisfy the demands of high temperature and also high pressure for handling floating feed.

Open up the pressure relief opening when feeding, to make sure that when the material reaches the stress alleviation hole, the pressure in the sleeve is partly launched, as well as at the same time, some water vapor is likewise released from the stress relief hole.


These products are extruded by fish feed pellet extruder to the end of the extruding dental caries and afterwards compressed to get a hefty feed with high bulk density. This pressure relief hole can additionally be made use of to leave, to make sure that the product loses part of the water vapor throughout the forced motion.

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

( 2) A pressure regulating tool is added in the floating fish feed extruder machine (pressurization before the die). The stress policy of the fish feed pellet extruder is to mount a shut-off shutoff in between the extrusion dental caries and also the discharge design template to adjust the stress difference in between the extrusion dental caries and also the outside of the extrusion dental caries.

( 2 )Pressure cutting innovation (post-mold stress). A new type of density control system was developed for aquafeed. This density control system of fish feed pellet extruder adopts pressurized cutting modern technology to keep a certain positive pressure in the reducing chamber.

When the product goes into the cutting chamber from the puffing chamber, considering that the boiling point of water boosts with the pressure, the flash evaporation can be minimized to manage the level of expansion of the product, and the starch molecules are promptly solidified in the cutting chamber, and the product no more enters the typical stress from the reducing chamber.

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

This fish feed pellet extruder process method avoids managing various other variables that impact the degree of development, therefore decreasing the demand for manual operation, and at the same time, the controllability is more powerful than various other approaches.

At present, this brand-new fish feed pellet extruder modern technology has not been used in China, but this innovation is superior to the exhaust approach in regards to density control of extruded items and procedure as well as usage, as well as is a new direction for the growth of extruded innovation.

( 4) Managing the opening rate of the template. By transforming the opening rate of the discharge layout, the stress distinction prior to and also after the theme can be altered, so regarding accomplish the objective of controlling the density of the product. The hole is blocked.

2. Automatic control of fish feed extrusion process

The automatic control of the fish feed pellet extruder extrusion process describes the quick and also precise 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 improve work efficiency, but likewise boost item high quality stability. Designs of automatic control in the house and also abroad

There are researches on all sides. The automated control modern technology of the fish feed pellet extruder puffing process has made fantastic development, as well as a visualization control system of the puffing process has been established. The extruding system of fish feed pellet extruder based on solution industrial arrangement software application recognizes the aesthetic control of the extruding process

The sensor can be used to perform on-site discovery as well as feedback on the operating parameters of the fish feed pellet extruder, instantly change the pertinent functioning criteria of the floating fish feed pellet machine, and understand numerous pre-programmed by the operator.

Working parameters, with formula storage, report printing, alarm, vibrant screen and recording of functioning specifications. International computer automated control innovation has actually already been used in the field of feed processing

In the entire fish feed pellet extruder process, it has been established from a single computer system control system to an advanced automatic control system, which can present color images in the central control room, computer system program control and communication network for floating fish feed making machine procedure, it can finish all manufacturing procedures without unmanned procedure.

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

While the introduction of computer systems in my nation is generally to resolve the issue of manufacturing automation, only concentrating 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 improving product quality and other facets.

3. Power conserving in extrusion process.

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

At present, it is mostly via the study of reduced power consumption processing modern technology and the influence of major process criteria on power usage, and also the establishment of equivalent mathematical designs to accomplish the function of power saving and also consumption decrease.

In order to reduce the energy usage in the fish feed pellet extruder puffing process, some domestic feed manufacturers mostly take measures from the process. For instance, in the production process of suckling pig feed, the corn basic material utilized is not full puffed material, but part of the puffed product and part of the standard product.

In the later fish feed pellet extruder granulation process, processes such as development and also reduced temperature granulation are utilized to make certain that the power intake each item is decreased.

From the above analysis, it can be seen that it is still a bottleneck problem exactly how the process specification research study in the fish feed pellet extruder puffing process can be personified in minimizing power intake and also can be understood in actual manufacturing.

4. Application of extrusion in floating fish feed processing.

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

( 1 )The handling temperature is high and the moisture web content is large, and the product can be fully grown and weakened. The pellets are of top quality and also the feed titer is high;
( 2 )The flexible series of pellet thickness is big, which can adjust to the requirements of different feeding items and also different feeding atmospheres.

( 1) Puffed suckling pig feed

The essential indicators of suckling pig feed are hygiene as well as growth to prevent suckling pigs from diarrhea. The raw materials are treated with high temperature and high pressure, on the one hand, it kills pathogenic microorganisms, on the other hand, the starch material is fully cooked, as well as the soybean healthy protein is denatured and also detoxified, to ensure that the material is very easy to digest and absorb. Gelatinized starch can promote the production of lactic acid in pets as well as boost the antibacterial ability of animals.

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

① Enhanced feed titer. Extrusion ripens the starch, which is important for fish as raw starch is hard to digest. The starch is prepared, the cohesiveness of the product is boosted, as well as the developing effect is excellent. On the premise of making sure the top quality of pellets, the formula can be adjusted to minimize prices.

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

As a result, by changing the formula, adjusting the variety as well as content of starch and also binder, as well as adjusting the process parameters, that is, adjusting the moisture, pressure, temperature level, and so on, extruded pellets with various thickness can be created.

( 3) Puffed chicken feed

The formula of chicken feed contains high starch product as well as 15% -20% healthy 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 revealed that puffing can improve the food digestion and absorption price of feed for chickens. Extruded chicken feed, as a result of its little mass thickness, can lower chicken feed consumption, prevent obesity, and enhance egg production.

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

Ruminants such as livestock and also sheep can convert non-protein nitrogen (such as urea) right into pet healthy protein. The trick to adding urea to feed is how to manage the enhancement amount, uniform feed intake as well as urea decomposition price. Urea-expanded corn fixes these problems most successfully.

The urea, corn flour as well as ingredients are mixed in a certain percentage and after that get in the floating pellet machine, the corn flour is broadened, and the gelatinized starch and also urea form a covering framework. Urease inhibitors inhibit the task of urease. It inhibits the release rate of ammonia after urea disintegration from 2 facets, as well as prevents ammonia poisoning brought on by excess ammonia.

( 5) Rice bran conservation treatment.

Fresh rice bran has really energetic lipolytic enzymes, which can swiftly break down the oil included in rice bran into free lipids.

Fat as well as rancidity, so the storage space performance of fresh rice bran is very inadequate. The rancid as well as spoiled rice bran not only decreases the oil yield, yet also affects the development and advancement of livestock and also poultry if fed as feed.

Therefore, fresh rice bran should be maintained fresh in time. Extrusion, high temperature, high pressure and also high shear can suspend lipase and also stop rancidity and degeneration. Extrusion has actually become a brand-new pretreatment process in rice bran oil production.

( 6) Cleansing of oilseed meal healthy protein.

In addition to soybean cake (dish), the cake (dish) gotten from rapeseed, cottonseed, sunflower seed, castor and various other oilseeds also consists of a specific amount of healthy protein, which is a superb resource of feed healthy protein. Nonetheless, different oil cakes (consisting of soybean meal) can not be directly made use of to create feed, due to the fact that they all contain a specific quantity of anti-nutritional variables or other unsafe parts.

Oil cake (meal) should be cleansed before it can be used. Cleansing techniques include chemical and physical techniques. Oilseed cake (dish) extrusion detoxing is a contemporary innovation related to oil cake (dish) therapy by extrusion technology.

( 7) Feather puffing processing.

As a result of the presence of disulfide bonds and hydrogen bonds in between feather polypeptide chains, the structure of feather protein is particularly secure, as well as animal gastrointestinal enzymes are generally not able to digest as well as disintegrate, so the plume extrusion modern technology has actually been established.

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

When the floating pellet machine extrusion temperature level is high, the digestibility of the puffed feather item increases, but the amino acid content of the product lowers correspondingly, and the healthy protein quality of the product decreases.

Feather dish has high protein material, yet the amino acid is not balanced sufficient. In order to fix this trouble, hen viscera, hen blood and also plumes can be mixed and processed into digestive tract feather dish.


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

The use of waste steam as well as waste warm for conditioning makes the machine more environmentally friendly and adapts to the fad of the moments. Extrusion innovation of fish feed pellet extruder is extensively used in aquatic, swine as well as ruminant feeds, which has a considerable impact on transforming feed high quality and minimizing costs.

With the development of fish feed pellet extruder extruding innovation, more extensive research study is needed on how to precisely manage the expansiveness and also extruding quality of extruded feed, and enhance the automation of extruding.
