Jatropha fruit shelling is a cleaning process in which the outer shells are detached from the fruits to produce clean seeds. The seeds can be further processed to produce white kernels by removing the husks (outer coating) from the seeds. The technology of seed cleaning is well established for other crops such as barley, coffee and beans [52–54]. The physical characteristics used to separate the seeds include size, length, weight, shape and surface texture [55]. The most effective differences between the seed/kernel and undesirable material should be firstly identified for the selection of a suitable separation mechanism.
