Traditional shelling in some countries is done by hand or by some form of mortar and pestle,or some country use manual peanut sheller machine.it requires a lot of labor. With the peanut sheller machine, the user loads the desired crop at the feeder downside. HT series peanut shelling machine is mainly composed of feeding hopper,shelling cylinder,motor, frame, fan, separation sieve etc. The structure and work principle is almost same of peanut sheller.Basically with hand-feeding, double drum for shelling, wind blowing, gravity separation sieve for selecting.
The peanut sheller machine are capable of shelling the same variety of crops such as jatropha curcas, shea, dried coffee etc. Start the machine,this peanut shelling machine need feed material manually first ,the fan creates centrifugal force, which pushes the nuts upside of the feeder automatically. There, the nuts are pulled down by gravity. As they descend, the gap of the roller cylinders gradually narrows. The shell of each nut is broken at the point where the gap is sufficiently narrow and the rotor motion causes sufficient friction to crack open the shell. The tapered gap allows a range of nut sizes to be shelled. The kernels and broken shell fragments fall into the output of material and are later separated by screen.if you wanna clean hulled peanut better ,you can use a grain cleaner machine .
