Why does the aquatic feed industry need screw extruder?
Clicks:
With the development and integration of the international puffed fishery industry in recent years, the development of group companies will become stronger and more professional. At the same time, consumer demand for aquatic products is getting stronger and stronger, and quality requirements are getting higher and higher. Therefore, the demand for aquatic equipment in the future will be large-scale, professional and intelligent.
The demand of the aquatic industry is constantly expanding, and the pellets required by the aquatic industry will be more and more. Then, the demand for aquatic feed pellet production lines also will be more and more.
Extrusion processing is a process that raw materials undergo high temperature, high pressure, and instantaneous curing. It integrates transportation, crushing, extrusion, mixing, shearing, high temperature disinfection and molding, and can process thick, high fat, high water. This raw material is incomparable with ordinary production technology, so it is increasingly used in the production of high-end feed and food such as aquatic feed, pet feed, and special breeding.
2.Processing process
Fine crushing of raw materials → ingredients, mixing → puffing → pelletizing → drying → spraying → cooling → metering and packing.
Processing process
3.Expansion effect of fish feed extruder
The expansion effect of the aquatic feed produced by the selected extruder should meet the following requirements:
A. Particle forming rate ≥99%;
B. Particle floating rate = 100%, sinking rate ≥99%;
C. Uniform particle size, consistent color and luster, good water resistance;
D. Floating materials should be kept in water for 10 hours, and sinking materials should be kept in water for 3 hours.
4. the life of the extruder
Screw extruders from different manufacturers have very different service lives due to their different transmission mechanisms, structural characteristics, materials used, and processing techniques. When selecting the extruder, we should first pay attention to whether the overall structure design is reasonable, the manufacturing process of each component, the selection of materials are good, and the wear resistance of the wearing parts. Energy consumption.
At present, the types of formulas on the market can basically be included in the following ten categories, and now there are corresponding mature configurations.
