Floating Fish Feed Making Machine
Floating fish feed making machine, also called floating feed extruder machine, floating fish feed machine. Based on the characteristics of floating fish, floating fish feed pellet making machine refers to floating fish feed machines.
With the continuous development and progress of feed production technology and equipment, in the production process of aquatic feed, floating fish twin screw extruder machines are more and more widely used, and extruded aquatic feed has been gradually applied and developed in production.
Richi Machinery pursues to provide customers with more abundant and systematic integrated floating fish feed production line solutions. The company’s R&D team has invested a lot of money to develop a new floating fish feed machine that can meet the diverse needs of customers with high quality and high output.
Floating Fish Feed Pellet Machine Types
Floating fish feed making machine is a combination of screw and machine boring.
When the material is conveyed to the extrusion cavity by extrusion, the material is subjected to mixing, stirring, friction and shearing forces to form a hydrothermal conditioning environment and play a role in sterilization, promote the comprehensive effects of starch gelatinization, crude fiber degradation, etc.
Due to the pressure difference between the extrusion cavity and the outside world, the material extrusion template hole will expand rapidly to achieve the purpose of puffing. It meets the needs of floating fish feed mills for production capacity and production of different varieties and specifications.
Single Screw Floating Fish Feed Pellet Machine
At present, the mainstream floating fish feed equipment is mainly twin-screw floating fish pellet machine and single-screw floating fish pellet machine.
Twin Screw fish Feed Making Machine
Compared with single-screw floating fish pellet machines, twin-screw floating fish feed pellet mills can be used in a wider range. Due to the assistance of the two screws, the direction of the material during the extrusion process is ideally controlled to avoid reverse gap flow, the material is balanced in force, the residence time in the machine is consistent, and the product is uniform.
Even if the moisture content of the raw material is more than 40% and the oil content is more than 17%, the product with high molding rate can still be obtained. The twin-screw floating feed machine does not need to set up resistance grooves on the inner wall of the machine bore, and there is little material residue in the machine, which is easy to clean up for changing varieties and before shutdown.
To produce high-grade aquatic products or feed raw materials are rich, such as containing high protein, high fat, the moisture range of the raw material is wide, and the diameter of the aquatic product changes greatly, it is more suitable to choose a twin-screw floating fish feed making machine.
In addition, when the product type changes greatly, such as the production of floating, sinking and slow sinking feed, the choice of twin-screw floating fish feed extruder machine is more adjustable, and the parameter settings are also easier to change.

02 Hard Pellet Machine Vs Floating Fish Feed Making Machine
In recent years, with the rapid development of aquafeed, the market awareness has gradually increased, and the demand has also increased year by year. This kind of equipment is required for both the equipment renovation of the old floating fish feed mill factory and the aquatic process equipment of the new floating fish feed production line.
Why use a floating feed extruder machine instead of a traditional fish hard feed pellet machine for processing floating fish feed? At present, extruded feed machinery has become the direction of aquatic feed production equipment, and will definitely replace the existing hard pellet feed machine.
At present, in many countries and regions in Europe, a new model of floating fish feed processing and breeding with extruded pellet feed as the mainstream has been formed. In recent years, with the development of the aquaculture industry in the direction of large-scale, intensive and specialization, its requirements for floating fish feed are getting higher and higher.
The floating fish compound feed produced by traditional ring die fish feed pellet machine exists. Poor stability in water, fast sedimentation, easy to cause feed loss and water pollution and other drawbacks, has become more and more unsuitable for the development of modern aquaculture.
The extruded aquafeed made by floating fish feed making machine can better solve these problems and is an ideal form of feed suitable for the development of modern aquaculture.
However, because the processing technology of aquatic floating fish feed is more complicated than that of hard pellets, in the actual production process, the same feed formula can be used in the aqua hard pellet fish feed production plant, but the product cannot be processed in the extrusion fish feed production line, or the same feed formula is not as good as the extruded floating feed.
The reason is that the temperature is as high as 120-150℃ in the process of puffing and granulation, and the whole floating fish feed mill process is high temperature, high pressure and high humidity, and the functions of most heat-sensitive vitamins, enzyme preparations and microbial preparations are destroyed.
Comparison Of Extruded Pellet Feed And Hard Pellet Feed
According to the feeding situation of floating fish in water, this feed is required to have high water stability and digestion and absorption rate, and it is difficult for traditional pelletizing process to meet the above requirements.
According to different processing techniques, fish feed is divided into hard pellet feed and extruded pellet feed. Although the ingredients of these two pellet feeds are the same, and the cost of extruded pellet feed is higher than that of hard pellet feed, the extruded pellet feed is still have better economic benefits can be produced with floating fish feed pellet machine.
In addition, based on the characteristics of sinking fish and shrimp, traditional fish feed pellet machines can be used. At least two layers of conditioners are required for sinking fish, and three layers of conditioners are required for processing shrimp feed.

Start A Floating Fish Feed Mill Plant
Fish feed extruder machine usually does not work independently, but forms a complete set of floating fish feed mill together with fish food grinder, micro pulverizer, feed mixer machine, fish feed dryer machine, pellet cooler machine, vibrating screen, automatic bagging machine, etc., to achieve accurate processing of different floating fish feed and improve the pertinence of products. increase its market value.
The floating fish feed production line process is: Cleaning – Grinding – 1st Mixing – Ultra-Fine Grinding – 2nd Batching (Micro proportioning, fat adding) – 2nd Mixing – Extrusion & Pelletizing – Drying & Cooling – Crumbling – 1st Screening – Liquid Adding & Coating – Cooling – 2nd Screening – Packaging – Stacking.
After the raw materials are initially cleaned, coarsely pulverized and mixed once, the mixture is pulverized into fine particles by an ultra-fine pulverizer;
Then clean up the impurities in the mixture or classify the mixture according to particle size;
After adding the small material, the mixture is subjected to heat and moisture treatment to make starch gelatinized, protein denatured, and material softened, so that the subsequent extruder can improve the quality and efficiency of granulation, and improve the palatability and stability of the feed. Improve the digestion and absorption rate of feed (conditioning process);
The mixture is formed into a bulky and porous feed through continuous mixing, conditioning, heating and pressurization, aging, extrusion die hole and sudden pressure reduction (expansion process);
After drying, the moisture content of the semi-finished product reaches the specified requirements, and then enters the oil-spraying bin, sprayed with grease by the spraying machine, and then sent to the cooler for cooling;
Finished products that meet the feed pellet size requirements are screened for post-packaging.
The crushing particle size of the raw materials should be below 0.5mm, which is not only conducive to puffing and granulation, but also improves the utilization rate of nutrients in the raw materials; adding water and mixing is a key step, and the moisture content of the raw materials should be controlled between 23% and 30%.
If the moisture is too low, it is difficult to puff, it is easy to block, and the moisture is too high, the puffing may be insufficient and affect the molding; the floating fish feed pelleting generally adopts a wet extrusion floating fish feed extruder, and the raw materials are extruded and pushed by the screw in the floating feed extruder machine.
High temperature and high pressure, the temperature and pressure drop sharply at the moment of passing through the die hole, so that the moisture in the raw material evaporates rapidly, the volume expands, and the specific gravity becomes lighter.

Supplementary Information Of Floating Fish Feed Production
How To Produce High Quality Floating Fish Pellet?
The advantages of floating fish feed are very suitable for modern aquaculture and have good market potential. Therefore, the majority of feed manufacturers should develop extruded floating feed varieties as much as possible.
High-end varieties should also be developed for the widely-raised four domestic fish, tilapia and other medium and low-grade varieties. At the same time, formula quality and production technology should be improved to expand production regulations, reduce floating pellet fish food production costs, and improve feed quality.
Main links affecting the production quality of floating fish pellet:
01 The Focus Of Product Processing Quality Control
The focus of extruded feed before extrusion is:
- whether the nutritional indicators meet the standard;
- whether the screening and removal of impurities is in place;
- whether the crushing particle size and mixing uniformity meet the standard;
- whether the cross-contamination prevention and control situation;
- whether the conditioning and maturation meets the standard, etc.
The focus is on the changes of nutritional indicators, pellet uniformity, specific gravity/floating rate, softening/water resistance time, pellet viscoelasticity after softening, powder content and appearance color.
02 Analysis Of Links Affecting Processing Quality
Recipe Of Raw Materials
The physical and chemical properties of raw materials, material pretreatment and formulation components will affect the processing quality of extruded materials. Specifically, the puffing quality coefficient of the raw material affects the puffing effect and puffing cost of the feed.
Whether the material is impurity-removed, whether the particle size meets the standard, and whether the pre-conditioning treatment is carried out will affect the puffing effect; and the starch, oil and crude fiber content of the feed formula are all in a certain extent, it determines the final effect of feed extrusion.
Floating Fish Feed Equipment
Host structure (uniaxial or biaxial, D:L value, distribution of spiral configuration), process equipment configuration (crushing, screening, drying and spraying) and extrusion die hole parameters (single hole structure and die hole area) will affect the quality of the extruded material.
The amount of water and steam added will affect the pellet size and appearance and color of the product; considering the production capacity demand and actual output of the floating fish feed production line, attention should be paid to the control of filling degree and material residence time when adjusting the screw speed; and the control of extruding temperature and extruding pressure is directly determined. The starch gelatinization degree and puffing degree were measured.
The wear and aging of the floating fish pellet machine and whether the operator is a novice will affect the quality of the extruded product to a certain extent.
This requires us to conduct operation training for novices before taking up the job and formulate a standardized operation manual for reference, and at the same time regularly track the wear of the screw, bushing and mold to decide later maintenance and replacement.

Characteristics Of Floating Fish Feed
The production of fish feed by extrusion floating fish pellet machine is an important research achievement in feed processing. The current floating fish feed making machine can produce floating, slow sinking and sinking feeds according to the needs of aquaculture production. Among them, the extruded floating fish feed has been well popularized and applied due to its special functions and functions that cannot be compared with sinking feeds.
The extruded floating fish feed is convenient for feeding and management
Because the extruded floating fish feed can float on the water surface for a long time, the feeder can observe the feeding situation of the fish well after feeding, and it is convenient to adjust the feeding amount according to the feeding situation of the fish; Changes and how fish come to the surface to feed to learn about their growth and health. Breeders can calculate the amount of bait to be fed according to the species, specifications, quantity, water temperature and feeding rate of the fish to be farmed, and feed them quickly, which not only saves a lot of time, but also improves labor productivity.
Extruded floating fish feed is beneficial to improve feed utilization rate
Due to the high temperature and high pressure processing conditions of extrusion and puffing, the starch in the feed is ripened, and the fat is more conducive to digestion and absorption, and the fiber structure and cell wall are destroyed and softened, and the gossypol in cottonseed meal and the antitrypsin in soybean are destroyed. and other harmful substances, thereby improving the palatability and digestion and absorption rate of the feed.
In addition, due to the physical and chemical changes in the extruding process, the extruded feed generally produces less than 1% of the powder, which directly improves the effective utilization of the feed. Under normal circumstances, the use of extruded floating feed for fish farming can save 5% to 10% of feed compared with powder or other pellet feeds.
The use of extruded floating fish feed can reduce the pollution of water quality
The extruded floating fish feed will not dissolve in the water for a long time, and the high-quality floating fish feed can float for more than 12 hours, and it is easy to observe and control when feeding, so as to reduce or avoid the impact of powder and remaining bait on the water body. pollution, which is extremely beneficial to environmental protection and the growth of fish.
Extruded floating fish feed has a wide range of application prospects. From the perspective of farming methods, extruded floating fish feed has a wide range of applicability, and floating fish feed can be used in pond fish farming, paddy field fish farming, running water fish farming, cage fish farming, industrial fish farming, and intensive farming on large water surfaces.
From the perspective of cultured species, whether it is freshwater fish or marine fish, except for a few benthic fish that are extremely difficult to domesticate to feed on the water surface, they can eat floating fish feed well. For species such as frogs and sea bass with special physiological functions, it is more convenient to use floating feed for breeding, and its superiority can be shown.
According to different species and different growth and development stages, we can produce extruded floating fish feeds that are suitable for their nutritional needs, which can well meet the needs of conventional aquaculture and special aquaculture for their feeds.
What kind of floating fish feed do you want to process? Tilapia feed? Catfish feed? carp feed? Herring feed? Eel feed? Salmon feed? Ornamental fish feed? Shrimp feed? Feel free to contact Richi Machinery for technical support.
Raw Material Selection For Floating Fish Feed
From the perspective of formula technology, floating fish feed can adjust the density and shape of feed, and can adapt to the world’s rich aquaculture species. At the same time, the puffing process improves the digestion and absorption rate of some raw materials, making the formula selection space and width wider. The complex processing technology of fish feed also puts forward higher requirements for raw materials. The following points should be paid attention to:
Pulverized Particle Size
The crushing particle size is very important for the extrusion process of floating fish feed. Coarse material crushing particles will reduce the expansion coefficient of the product and easily block the mold; it will affect the effect of pre-conditioning and extrusion mixing; it will cause great wear and tear on the floating fish feed making machine and high mechanical energy consumption; it will also make the appearance of the product pellets rough. Therefore, it is necessary to determine the most economical particle size according to the product grade and extrusion requirements.
Reasonable and slightly high starch content will increase the expansion coefficient and increase the floating water rate; make the extrusion operation width larger, and it is easy to stabilize the product quality; Improve pellet appearance quality. Better starch raw materials are high-gluten flour, corn flour and potato starch.
Crude Fat Content
For a single-shaft floating fish feed making machine, if the crude fat content of the raw material before extrusion exceeds 8%, the material will be poorly homogeneous during extrusion, the quality will be unstable, the viscosity of the product will be reduced, and the water resistance will be reduced; The force is reduced, and the floatation rate of the product is reduced.
Therefore, when the total fat content of the extruded floating feed exceeds 8% before extrusion, the excess oil should be added by spraying outside to reduce the impact on extrusion processing. It has been confirmed by production practice that high-fat raw materials are beneficial to improve the oil level. The minimum uniform external fuel injection is related to the particle size and surface smoothness. The smaller the particle, the easier it is to be uniform.
The source and content of crude protein of raw materials have a great influence on the extrusion effect. Generally speaking, animal protein has a large difference in puffing performance, while vegetable protein has better puffing performance as a whole. Within a certain range, the crude protein content is increased, the friction coefficient is small, the equipment wear is reduced, the product is well organized, and the viscoelasticity is increased.
Raw Materials For Fur And Shell
The larger the proportion of raw materials such as cottonseed meal, coconut seed meal, rapeseed meal, etc. in the formula, the more difficult the material is to be crushed, and the crushing efficiency decreases linearly. The irregular shape of fur and shell raw materials is also difficult to fine screen, which easily leads to mold blockage and increased production failure rate. For products with many shell raw materials, the bubbles generated during processing are easy to burst, and the appearance of the product particles is poor.
Use Of Hydrophilic Raw Materials
Aquatic adhesives such as polymethyl urea, sodium polyacrylate, etc., monosaccharides or polysaccharides such as sucrose, fructose, pectin or agar, etc., generally decrease the gel-forming ability after extrusion, and the bonding effect is not obvious. The hydrophilic properties of water-based raw materials significantly reduce the extrusion shear force during the extrusion process, resulting in a smaller puffing degree of the finished feed.

The Formula Principle Of Floating Fish Feed
The characteristic of floating fish feed is that it is extruded and has a certain porosity so that the specific gravity of the feed is smaller than that of water and kept floating on the water.
However, different feed materials have different puffing degrees. For some raw materials, such as fish meal, the puffing coefficient is very low. If a large amount of fish meal is used in the formula, it may not puff up. Some raw materials have higher expansion coefficients, such as cornstarch. Therefore, the expansion coefficient of the overall formula should be considered in the formula design, so that the product can meet the expansion requirements.
In addition, the oil content in the floating fish feed production line puffing process also affects the puffing coefficient, and the oil is easily oxidized at high temperature, especially the fish oil in the special aquatic feed. Therefore, for floating feeds with high oil requirements, some oil can only be added by spraying after pelleting, but not all of them can be added during mixing. Generally, it is ideal to control the oil content below 8% during mixing.

Storage Of Extruded Floating Pellet Fish Food
Due to the bulking effect, the extruded floating feed made by floating fish feed pellet making machine contains high porosity from the surface to the inside, so the diffusion rate of oxygen into the feed is many times faster than that of ordinary extruded pellets.
Therefore, extruded floating fish feed is more likely to deteriorate due to oxidation and moisture absorption than ordinary extruded feed. And the preservation conditions of extruded floating fish feed are more severe than ordinary extruded feed.
The pad can separate the floor from the feed, which not only prevents the moisture from the wet floor from directly diffusing into the feed, but also facilitates the ventilation and keeping the feed dry.
The extruded feed is generally sprayed with oil, and this part of the oil is easily exposed to oxygen due to the many pores of the extruded floating fish feed. Therefore, the higher the temperature, the more easily the oil is oxidized and rancid. Secondly, the extruded feed is much more hygroscopic than the ordinary extruded feed, and any moisture in the warehouse space is easily absorbed by the feed. Therefore, it is very important to keep the warehouse dry with good ventilation conditions.
Although the shelf life provided by the manufacturer is generally longer. However, in view of the characteristics of extruded feed that is easy to absorb moisture and easy to oxidize, it is best not to store it in the warehouse for too long, and it is generally best to use it up within 1 week. In addition, if it is stored in the warehouse for a long time, although it is still within the shelf life, it is best to check it carefully before using it. If you find a peculiar smell, it is best not to use it.
Use Of Extruded Floating Fish Feed
The extruded feed floats on the water surface, the feeding situation of the fish is clear at a glance, and it is easy to manage, which is the favorable side of the extruded feed. But the extruded feed is easy to absorb water, fluffy, and has a strong sense of satiety. Therefore, feeding slowly and for a longer period of time is more beneficial than fast feeding.
Secondly, after the extruded feed is sprinkled into the pond, it will quickly absorb the pond water. If the water quality of the pond is not good, the ammonia nitrogen and nitrite are too high, and the bacteria and algae are not good. feed, will greatly affect health, and even life-threatening.
In particular, algae in pond water produce some fat-soluble substances after aging, and these substances are often highly enriched on the oil film on the water surface. If extruded floating fish feed made by floating fish feed making machine is placed on the water surface with such oily film, a large amount of toxins may be absorbed in the feed.
Some fishes that are sensitive to toxins, such as eels, will refuse to eat (spit), while some fishes that are not sensitive to toxins or predatory fish are easily poisoned. There have been cases where channel catfish ingested extruded feeds that absorbed cyanobacterial neurotoxins in ponds. Cases of mass deaths after a few minutes of feeding.
Therefore, the use of extruded floating fish feed made by floating fish feed making machine requires higher water quality. If extruded feed is used in a pond with poor water quality, it is best to soak it with high-quality photosynthetic bacteria or EM bacteria solution first, and let it absorb water before feeding to avoid aquatic animals poisoning.
