In order to realize the mechanized shelling operation and improve the shelling efficiency in rubber fruit processing, a sheller mechine was developed. The shelling principle of the proposed mechanism is based on the ripping and rubbing effects produced by the compression and shearing action together. The shelling unit comprises cutting means, pressing means and separating means. The rubber fruit to be shelled fall into the cutting unit by gravity and are shelled by cutting and squeezing action. The shelled kernels and the broken shell drop to the separating means to be separated. The shelling machine is simple, easy to operate and lower cost, and can be as the reference for the development and comprehensive utilization of rubber fruit.
