How to Make Fish Shrimp Crab Feed

(1) Screening: The impurities in soybeans, corn and rapeseed not only affect the quality of products, but also directly affect the processing equipment and personal safety. The screening equipment removes large and long debris such as grass, straw, hemp rope, paper pieces, soil blocks, leaves, sticks and other debris in the raw materials. The screening process is completely closed, and qualified raw materials after screening are lifted into the silo for temporary storage.

(2) Crushing process: the screened material enters the crusher from the silo through the feeder and is crushed by the impact of the hammer .The particle size of the crushed material is about 01-3mm. The purpose of crushing is to improve the quality of subsequent processes and improve work efficiency.

(3) Heating puffing: The method of item puffing is wet puffing, which is a gelatinization process under the combined effects of moisture, heat, mechanical shear, friction, kneading and pressure difference. Generally, the gelatinization degree can reach 90%-100%.

(4) Cooling of extruded material: In the process of extruding, a large amount of heat is generated due to the introduction of high temperature and high humidity steam while the material is squeezed, which makes the temperature and humidity of the extruded particles higher. For adhesion and mildew, the moisture must be reduced to below 14%, and the temperature must be lowered to below 8°C higher than the air temperature. SKLN counterflow cooler is used for cooling.

(5) Crushing: The cooled material enters the pulverizer through the impeller feeder. The purpose of pulverization is to increase the material The specific surface area can improve the utilization rate of subsequent feed production and increase the contact area of ​​digestive enzymes with the raw materials; reduce the energy consumption of chewing during the animal feeding process, which is beneficial to increase the feed return.

(6) Packaging: Finally, according to market demand, the crushed powder is packaged in plastic bags in the packaging room into finished products for sale.

Advantages of Aquatic Feed Pellets

• High digestive utilization ratio: in the process of extruding, the heat, steam, pressure and other mechanical actions can promote the degree of starch pasting, break and soften the cell wall part of fiber structure and release some digestible materials, which is in favor of the digestion and absorption for aquatic livestock.
• Convenient feeding management: extruded fish feed can float on water for a long time, which makes it easier to observe fish ingestion so as to adjust feeding quantity timely and master fish growth and health state.
• Slight pollution to environment: with good stability in water, extruded fish feed makes it possible to decrease the dissolution and sediment of feed nutrition and then reduce loss and waste, alleviating water pollution.
• In addition, with longer and easier storage period, fish feed via extrusion process, including floating, sinking and slow sinking types, also can satisfy different demands of aquatic animals with various ingestion habits. All in all, extruded fish feed has gained great popularity among fish farms and other aquaculture industry around the world.
