With the further development of fish farming industry, compound fish food pellets have obtained more and more wide applications in virtue of unique advantages including high nutrient, good palatability, strong digestibility and so on. There are 3 types of sinking fish feeds machine available for processing sinking fish feed pellets: sinking pellet machine with two-layer conditioner, three-layer conditioner sinking pellet feed machine and sinking fish feed extruder machine.
Studies have shown that among the many factors that affect the ecosystem and the disease resistance of fishes, the nutrition and quality of feed is one of the key factors. Comprehensive nutrition and high quality, and the use and popularization of compound feed are key signs of technological progress in aquaculture.
As an industry with broad development prospects, how to seize the opportunity? The answer is the leading aquatic feed processing technology and aqua feed equipment.
RICHI is one of the very few companies with the ability to design, manufacture and supply each and every key sinking fish feed making machine in the sinking fish feed plant, as well as designing and building the fish feed production plant as a whole.
Wherever your fish feed plant is located and whether you produce feed pellets for sinking fish, floating fish, shrimp, trout, tropical fish, catfish, tilapia, carp, saltwater fish, prawn, etc., we offer a full range of fish feed processing machines and equipment – from raw material intake to finished feed storage.
Pellet Richi is one of the fish feed machine manufacturers and fish feed plant suppliers in China, we have rich experience of providing complete fish feed plant solutuions and fish feed making machine for various fish feed, shrimp feed, etc.

Under the action of the squeezing force of the ring die and pressure roller of the sinking fish feed machine, the powders with a certain temperature and humidity are close to each other and rearranged. The air contained in the powder particles is gradually squeezed away, and the powder close to each other, the connecting force increases, and finally it is pressed into pellets by sinking fish feed pellet machine with a certain density and strength.
In the granulation process of the sinking fish feed pellet machine, the protein and sugar in the feed become plastic when heated, and the starch is partially gelatinized. Therefore, the granulation process of the sinking pellet feed machine for fish can be said to be an extrusion thermoplastic process, but after the feed is granulated, the gelatinization degree of the starch is generally about 30% or lower, and this is mainly accomplished by steam conditioning.
If you want to increase the gelatinization degree of starch, you must extend the conditioning time or use a conditioning tank. Compared with a sinking fish feed extruder machine, the degree of gelatinization improved by the sinking fish feed machine is limited. However, the sinking pellets for aquatic animals produced by the sinking fish feed pellets machine is very suitable for sinking aquatic animals and benthic prawns and herrings.
Some sinking fish feed manufactuers who process sinking fish food will configure a sink fish feed pellet machine after the pelletizing section, but we generally do not recommend this. After crushing, the surface of the sinking fish food pellets is rough, and it is easy to absorb water to collapse the sinking fish food pellets, which affects the stability of sinking fish feed in water.
If the powder is directly pressed into small fish sinking pellets, the surface of the fish sinking pellets is smooth and not easily corroded by water, which can improve the stability of the fish sinking pellets in water.
In addition, in the sinking fish feeds pelleting machine's granulation processing method, it can be used to emphasize the quality of maturation, the fish feed making material is double-layered or three-layer strengthened and tempered, so that the starch is fully gelatinized, and the digestibility of the bait can also be greatly improved.

First, the different raw materials are pulverized by a fish feed pulverizer, and then the sinking fish feed raw materials are mixed through a fish feed mixer. The mixed fish feed production raw materials are the semi-finished products of the compound sinking fish food.
The next step is the process of making sinking fish food pellets. The pre-mixed compound feed enters the conditioner of the sinking fish feed pellet machine, and then passes through the ring die and pressure roller of the sinking fish feed pellet machine to compress the sinking fish food pellets.
The diameter of the sinking fish feed pellet machine ring die is the diameter of the sinking fish food. When making sinking fish food pellets of different sizes, the sinking fish feed pellet machine ring die of different diameters is used, and the fish sinking pellets extruded are the finished product.
There are two important points: First, the performance of the fish feed grinder will determine the fineness of the raw materials. Second, the temperature at which the crushed powder feed enters the conditioner is about 80-90 degrees.
This temperature can make the powder semi-cooked, and finally the refined powder is pelletized into sinking fish food pellets through the sinking fish feed machine ring die and pressure roller. Therefore, the sinking fish food pellets is semi-cooked feed.
The manufacturing process of sinking fish feed extruder machine is roughly the same as that of pellets, but the extruded sinking fish food has two more processes than sinking feed pellet machine technology.
In addition, the water content of extruded feed is much lower than that of pellet feed. Because water is lost during the high temperature and high pressure process, 1.1 tons of powdered raw materials are made into pellets and only about 1 ton of finished extruded feed.
