The feed pellet machine, as the name suggests, mainly presses feed raw materials into granules through pressing. Its core lies in the coordinated work of the pressure wheel and the mold. The pressure wheel rotates under the drive of the main shaft, pushing the material into the mold hole. Through the special shape of the mold and the pressing effect of the pressure wheel, the material generates shear force and forms particles. This processing method does not require the addition of water. The inside of the particles is matured deeply, the surface is smooth, the hardness is high, and it can be stored for a long time. The feed pellet machine has a simple structure, easy operation and high production efficiency, and can meet the needs of large-scale feed processing.
The working principle of the feed extruder is completely different. It mainly uses extrusion, heating and shearing to instantaneously mature the material under high temperature and pressure, and then suddenly reduces the pressure and temperature to rapidly expand the volume of the material to form puffed matter. This processing method can gelatinize the starch in the feed, denature the protein, and improve the digestibility and nutritional value of the feed. The structure of the feed extruder is relatively complex, including a feeding system, an expansion chamber, a cooling system, a cutting system, etc., and can achieve continuous production.
From the perspective of product form, the feed produced by the feed pellet machine is in a dense granular shape, which not only tastes good, but is also easy to store and transport. The feed produced by the feed extruder takes on a porous and loose expanded shape, which is easier for animals to digest and absorb.
In general, feed pellet machines and feed extruders each have their own unique working principles and structural characteristics, and the feed forms and uses they produce are also different. When choosing which equipment to use, you need to comprehensively consider factors such as the type of feed, the type of animal, and the scale of production.
