Product introduction

With the rapid development of the economy, all kinds of pet, fish, shrimp and other feed pellets is increasing quickly, and are moving towards commercialization and scale, the market is unusually hot.  Aquatic feed pellet extruder machinery is a kind of professional feed pellets machine to meet the market demand. The equipment uses corn, soybean and other grains as raw material, directly into the machinery can be expanded into different kind shapes feed pellet which is unique taste, rich nutrition, loved by many pets. Very easy to operate and high production efficiency, aquatic feed pellet extruder machinery can bring you endless profit.

Product advantages

  1. The aquatic feed pellet size can be from 0.9-15mm to feed different size fishes.
  2. aquatic feed pellets produced by this aquatic feed extruder are solid, water resistant and damp resistant.
  3. The puffing aquatic feed pellets can float on the water surface without dissolution for over 12 hours.
  4. Salmonellosis and bacterial infections can be killed by high temperature and high pressure, which makes the pellets more safer for aquatices, shrimps, etc.
  5. Key parts have high processing precision and long service life.
  6. Producing aquatic feed pellets with different diameters can be realized through changing different molds.
  7. Reasonable structure ensures reliable and safe operation.

Raw Materials

The material selection is very wide, such as soybean meal, corn flour, wheat meal, bone meal, meat meal, fish meal and so on. Here is the material requirement:

What is Fish Feed Extrusion Process

Commercial fish feed extrusion process refers to cook the mixture of feed ingredients under high temperature, moisture and high pressure by means of fish feed extruder within short time, whereby the high temperature is a direct result of friction(dry extrusion) or preconditioning and steam injection (wet extrusion). As a technological treatment, extrusion can make it possible to process a variety of fish feed ingredients, such as soybean, corn, rice, peas and raw materials with high water content. According to the moisture content of raw materials treatment, fish feed extrusion process can be divided into two types – dry type extrusion and wet type extrusion.

Dry type extrusion process: in the process of extruding, it adopts the heat from friction for warming materials, forces materials to pass through die hole and gets certain pressure simultaneously under the action of screw extrusion. After extruding out of die hole, materials pressure will decrease sharply and moisture will evaporate so as to achieve the goal of extrusion. During this whole process, water content is always about 15% – 20%.

Wet type extrusion process: its principle is similar to that of dry type extrusion, but it needs to add water and vapor to make moisture up to 20% or even over 30% because the rising of materials temperature depends on the addition of vapor.

Advantages of Aquatic Feed Pellets

  1. Convenient feeding management: extruded aquatic feed can float on water for a long time, which makes it easier to observe aquatic ingestion so as to adjust feeding quantity timely and master aquatic growth and health state.
  2. Slight pollution to environment: with good stability in water, extruded aquatic feed makes it possible to decrease the dissolution and sediment of feed nutrition and then reduce loss and waste, alleviating water pollution.
  3. 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.
  4. In addition, with longer and easier storage period, aquatic 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 aquatic feed has gained great popularity among aquatic farms and other aquaculture industry around the world.
