This peanut shelling machine is used to shell peanut; can separate shells and kernels with high-efficiency and almost without damage to the kernel; and the shelling rate can be ≥95%, the breaking rate is≤5%. Peanut Shelling Machine consists of rasp bar, stake, intaglio, fan, gravity separator and second bucket, etc. The whole machine frame is made of high-quality steel and the shelling chamber is made of stainless steel. After starting, the shells of peanuts are shelled by the rolling force between the rotating rasp bar and the fixed intaglio, and then shells and kernels fall through the grid mesh down to the air duct, and the fan blows shells out. The kernels and the unshelled small peanuts fall into the gravity separator. The separated kernels are sent upward to the outlet and the separated unshelled small peanuts are sent downwards to the elevator, and the elevator sends the unshelled peanut to the fine grid mesh to be shelled again until the whole batch of peanuts are all shelled.
