Fish Feed Processing Machine

Applications Of Fish Feed Processing Machine

The feed industry is the most industrialized industry in agriculture. It is the link that connects the planting industry, breeding industry, and animal product processing industry, and plays a pivotal role in agriculture. In the feed industry, the production technology of aquatic fish feed is very different from the traditional processing technology of livestock and poultry feed.

According to the characteristics of the variety of aquatic fish feeds, large changes in raw materials, high requirements for grinding fineness and poor material fluidity, the design of the production process generally adopts secondary grinding and mixing of secondary ingredients to complete the processing of powdered raw materials; and pressed by the fish feed pellet making machine into shape, and then the pellet for fish is processed into the finished product packaging system through drying, grease spraying, cooling and screening and other fish feed production processes.

Fish pellet feed has the advantages of uniform nutrient distribution, high digestibility, easy storage and no automatic classification, etc., and it is increasingly widely used in the aquaculture industry. Pelleting by fish feed processing machine is an important link in the fish feed making process of pellet feed, which directly affects the quality of pellet feed.

Reducing fish feed processing machine wear and power consumption, reducing production costs, ensuring pelleting quality and increasing pelleting output are the goals that fish feed companies and fish feed manufacturers pursue in the fish feed making process of producing pellets.

Technical Features Of Fish Feed Processing Machine

1. The fish feed processing machine adopts advanced hole layout technology and die hole structure make pellets uniform and smooth.
2. Long service life, mould and gear＞5000h. The fish food making machine can process fast sinking feed with about 30% starch.
3. The fish feed production machine can produce 100% floating feed and 100% sinking feed only with two-layer and three-layer conditioner.
4. The fish food production machine can reduce the dependence of feed formula and save the cost of raw materials.
5. Precise and unique fish food processing machine ring die pelletizing structure increases oil content up to 12%.

Working Principle Of Fish Feed Processing Machine

For preparing the pellet for fish, the fish feed making raw materials need to be converted into powdered form by fish feed grinding machine. The resultant mixture is then put into the hopper of the fish feed making machine. A very high pressure is exerted due to the continuous rotation of the roller and the mixture gets passed through the holes made in the pellet machine ring die. As the holes are cylindrical in shape, the fish food pellets take the same shape and then while coming out from the other end of the fish pellet making machine die they are cut into the desired length.

How to control the water resistance of fish food pellets made by fish feed making machine?

Fish food pellets refers to the pellet for fish produced by pressing the processed powdered compound feed through a fish feed pelleting machine, which has comprehensive nutrition and strong stability.

Compared with powdered feed, fish pellets has many advantages, such as not easy to collapse in the water, not easy to pollute the water body, easy to digest and absorb, etc., which are favored by the majority of farmers. How to judge whether fish pond food pellets is of high quality, the water resistance standard is very important.

Water resistance of fish food pellets made by fish food making machine

The water resistance of fish feed pellet made by fish feed making machine refers to the resistance to solubility of feed in water, and usually means the rate of loss of fish feed pellets in water under specified conditions.

Many national standards stipulate that the water resistance of fish food pellets must be at least 30 minutes. Poor water resistance of fish food pellets made by fish food making machine will cause feed to dissolve in the water before it is eaten, resulting in wastage of feed and polluting water quality.

Reasons for poor water resistance of fish food pellets made by fish feed making machine

The reasons for poor water resistance of general fish food pellets are:

1. The tempering time is short and the tempering temperature is low, resulting in insufficient tempering, low temperature, insufficient maturity, and insufficient moisture.
2. The content of cohesive raw materials such as starch is insufficient.
3. The compression ratio of the fish feed making machine ring die is too low. Generally, under the premise of a certain feed ingredient composition and ratio, the larger the compression ratio of the fish feed processing machine ring die aperture, the longer the water resistance time of the fish food pellets.
4. The fish food pellets fat content is too high or the crude fiber content is too high.
5. The crushing fineness is not enough. The particle size of the fish food pellets raw material is too large and the stability of the particles is poor, and excessive pulverization will increase the production cost. Especially fish feed requires stricter crushing particle size.
6. The composition and ratio of fish food pellets raw materials, the composition and ratio of fish food pellets raw materials have a greater impact on the water resistance of fish food pellets made by fish feed making machine.
   The greater the proportion of some feed ingredients in the fish feed formula, the better the water resistance of the fish food made by fish feed making machine. In fish feed production process, the high cohesiveness of slightly crushed starch is often used to improve the water resistance of fish feed pellets, and it can also be improved by adding a binder.

How to control the water resistance of fish food pellets made by fish feed making machine?

• Increase the moisture content of the fish feed making raw material, adjust the angle of the blades to extend the conditioning time, and increase the conditioning steam of the fish feed pelleting machine.
• Add steam to the interlayer of the fish feed pelleting machine conditioner, and add post-curing and stabilizing equipment if necessary.
• Adjust the fish feed formula to appropriately increase the starch content, reduce the fat and crude fiber content; add binders if necessary.
• Increase the compression ratio of the fish feed making machine ring die and increase the fineness of the fish feed pellet.
• Pay attention to choosing the appropriate cooling time and cooling air volume, so as not to affect the hardness and wear resistance of the fish feed pellet made by fish food making machine. In the fish feed production process for fish pellets, there are many factors that affect the water resistance of fish pellet feed by fish food making machine.

The above are the reasons and improvement methods, which are only for reference by the majority of fish feed producers.
