Peanut sheller takes off the peanut shell by quickly rotating the body and keeps the peanut kernels intact. During the working process, peanuts firstly enters the feeding hopper quantitatively, uniformly and continuously. The peanut is smashed by repeated blowing, friction and collisions of the rotor. Peanut kernels and the broken peanut shells under the rotation of the rotor of wind pressure and blow, through a certain aperture sieve (peanut threshing with big hole mesh for the first time, after cleaning the small fruit skin changing sieve into a small hole on the second shell), then, peanut shells, particles are rotating fan blow force, the lightweight of peanut shell was blown out of the body, peanut kernels by a screening of vibrating screen to achieve the purpose of cleaning.
