The various raw materials required by the feed mill are put into storage or put directly into use through certain standardized procedures. Divided into bulk raw material receiving, packaged raw material receiving, liquid raw material receiving.

Clean out the impurities and iron-containing substances in the raw material, and let the clean materials enter the feed hammer mill for crushing. Its significance is to ensure the product quality and ensure the normal operation of the crusher.

The raw materials that need to be crushed enter the buffer bin after going through the cleaning section,and then enter the feed crushing machine. According to the requirements of the formula, the raw materials are crushed to a certain degree of fineness, and then transported to the next section without wind.

According to the requirements of the feed formula, different raw materials are mixed here with additives, oil/fat, medicines, etc. It is accurately weighed through the PLC control program, and the weighing, and mixing process is completed in the shortest time.

The crushed powder materials are pelletized, and feed pellets of different sizes can be produced by changing different ring dies. Pellet feed has comprehensive nutrition and strong stability, which can improve the digestibility of feed by animals, reduce animal picky eating, convenient storage and transportation, and economical.

The temperature of the pellets coming out of the pellet machine is 80 degrees, and the moisture is 15-16%. It is not suitable for packaging, so it needs to enter the counter-flow cooler to slowly cool the pellet feed to room temperature.

Through sieving, the qualified pellets are extracted, the unqualified small pellets or powder feed are sieved out and re-granulated, and the pellets whose geometric size is larger than the qualified pellet product are returned to the pellet crumbler machine for crumbling.

Our conveyors cover all feed processing sections throughout your feed plant.We can customize a conveying system by using any combination of bucket elevators,screw conveyors,scraper conveyors.

Finished feed need to be packed,ready to dispatch.Packaging system offers maximum flexibility. Matching requirements in product suitability and capacity. It is suitable for pellet feed and powder feed products,and can be manual or automatic bagging depends on requirement.

Aquatic animals, like crab, have differences in their living environment, living habits and physiological functions compared with terrestrial animals. These include:

(1) Crab live in water for their life, and their feed must have better stability in water to prevent the loss of feed nutrients and reduce the pollution of feed to the water environment;

(2) Crab have short digestive tract, and their digestive enzyme activity is low, so their digestibility is lower than that of the terrestrial animals. Therefore, the crushing fineness of feed materials is higher, in order to improve the digestibility and utilization of feed;

(3) because of the different living and feeding habits of different types aquatic animals in different growth stages, their nutrition requiment and feed products form differ.

So, the processing technology and processing equipment of Crab feed are different from that of terrestrial animals.

Richi machinery good stability crab feed pellet plant production line can produce various crab feed pellets, including port crab feed, blue crab feed, river crab feed, hairy crab feed, etc. The raw materials of the complete crab feed pellet plant production line include fishmeal, fermented blood meal, bean cake, cotton kernel cake, secondary powder, corn flour, bone meal, yeast powder, multivitamin premix, starch, etc. The final pellet produced is between 0.5 mm-12mm. For example, grass shrimp:0.5mm-3mm pellet, red tail shrimp:0.55mm-3mm pellet, monarch shrimp:0.5mm-3mm pellet, freshwater shrimp:0.5mm-3mm pellet, prawn:0.5m-3mm pellet.

Raw Material

raw materials including grain, fishmeal, bone meal, bean cake, peanut meal, rice bran,wheat bran,clam shell powder,alcohol masterbatch,soybean phosphatide, ,shrimp flour,salmon powder,feed yeast,etc.

How to Make 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 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.
