Ring die type fish feed pelleting mill
The ring die fish feed pellet machine should be more familiar than the flat die type, because many domestic and foreign feed companies are using ring molding machine. The raw material is fine feed, such as corn, soybean meal, cottonseed meal, and so on, the adhesion rate is high. In addition the granulation with steam conditioner, can advance to the softening and curing effect on the material, ...

Difference Between Dry and Wet Fish Feed Extruder
Fish feed making machine can be divided into dry type and wet type fish feed extruder according to the moisture of the raw materials. 1. Dry type Heating the materials by the frictional force, this floating fish feed extruder machine squeezes raw materials out of the holes of the mold under the action of screw extruder. The pressure and temperature of the pellets sharply decreases when coming out ...

Working Principle of Dry Type Fish Feed Extruder Machine
There is no need to heat outside the machine, through the screw extruding of the raw material, heat is produced and gathered during the rotary working process in the airtight environment, and during the high temperature ripening process, the starch and fiber of the raw material become swell. Then under the pressure-tight condition, material will be formed into pellets by shaping mould. At the ...
