What is the working principle of pumpkin seed shelling machine?

• Firstly,we need to  know the comprises of shelling machine.
• The sheller comprises a frame, a fan, a rotor, a single-phase motor, the screen (size 2), into the hopper, vibration screen, belt pulley and the transmission belt.
• Then, let  me introduce the working principle.
• The machine normal operation, the quantitative seeds continuously and evenly into the hopper, the seeds in the rotor friction, collision, strike repeatedly under the action of broken, broken grain and seeds in the seed shell rotary pressure and blow rotor under the screen through certain pore size (peanut first threshing by large hole sieve, small after the election, the Qing replaced fruit second times) and small screen filtration and separation. The melon seed shell and granule are blown out of the machine body under the action of the blowing force of the rotary fan, and the heavy weight peanut granules are screened by vibrating screen to reach the purpose of cleaning.
