The peanut sheller is an agricultural processing machine designed to remove shells from peanuts efficiently while minimizing kernel breakage. It typically consists of a feeding hopper, shelling chamber, rotating drum or beater system, concave sieve, blower for separation, and separate outlets for kernels and shells. The machine is powered by an electric motor or engine and is built with a strong metal frame to withstand continuous operation. It improves productivity by replacing manual shelling and ensuring cleaner, faster peanut processing.

In operation, dried peanuts are fed into the hopper where they enter the rotating shelling chamber. The rotating drum or beaters rub and impact the pods against the concave surface, breaking the shells and releasing the kernels. A built-in blower and sieve system then separate the lighter shells from the heavier kernels. Clean kernels are discharged through one outlet while shells are expelled through another. Proper adjustment of feeding rate and clearance helps reduce kernel damage and improve shelling efficiency.
