The working principle is:

After the normal operation of the machine, the melon seeds will be put into the feeding hopper quantitatively, uniformly and continuously, and the melon seeds will be crushed under the action of repeated strikes, sassafras and collision of the rotor, and the melon seeds grains and crushed melon seeds shells will be filtered and separated through a certain aperture of the sieve under the rotating wind pressure of the rotor. Then, the melon shells and melon particles in the rotating fan under the action of the blowing force, so that the light weight of the melon shells blown out of the body, the heavier weight of the melon particles through the vibrating screen to achieve the purpose of cleaning. Melon seeds with shells from the shelling machine inlet into the shell and by the impeller repeated impact, can be peeled off the shell, and then after screening, you get melon seeds kernel.
