Sinking Fish Feed Pellet Machine

Applications Of Sinking Fish Feed Pellet 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.

Working Principle Of Sinking Fish Feed Pellet Machine

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.

Parameter And Model Of Sinking Fish Feed Pellet Machine

Difference between using sinking fish feed pellet machine and sinking fish feed extruder machine to process sinking fish food

Production process of sinking fish feed pellet machine for sinking fish feed factory line

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.

Production process of sinking fish feed extruder machine for sinking fish feed factory line

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.

• First, it will be pulverized a second time before making sinking fish food pellets, that is, ultra-fine pulverization, and the fineness of the raw material powder is finer than that of the sinking fish feed pellets machine production.
• The second is the sinking fish feed extruder machine. The feed material temperature in the extrusion cavity is as high as 110-200 degrees, under high pressure, in the environment, continuous mixing, tempering, heating, pressurization, maturation, extrusion, and extrusion of the film hole, suddenly reduce the pressure to form a bulky and porous pellet feed.

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.

1. Water entering properties
   In order to ensure that the pellet feed does not melt for a long time, it is necessary to add a large amount of binders such as high-gluten flour or other animal-absorbable binders to achieve the effect of long-term water retention. The sinking fish feed extruder machine is not used, because it is purely matured, it can become a puffed state after a few hours of water, just like a sponge.
2. Dust
   Pellet feed dust is obviously excess extruded feed.
3. Technology manufacturing cost
   The manufacturing cost of extruded feed is 1-1.5 times the manufacturing cost of pellet feed made by sinking fish pellet feed machine.
4. Absorption problem
   Extruded feed made by sinking fish feed extruder machine has gone through high temperature and pressure to eliminate a lot of bacteria, taste good, and absorb better than similar raw material pellets.
5. Market price
   Because the price of sinking fish feed extruder machine and sinking fish feed factory extruding process cost is much higher, the price of extruded feed is generally higher than that of pellet feed made by sinking fish feed pellet production line, and extruded is generally used to make high-end fish feed.
