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:
The 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 a 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, the 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 the 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.
