Traditionally groundnut was decorticated by finger tip of hand/ beating on stones etc. which are drudgery prone with time consuming actions.
A sitting groundnut decorticator is an oscillatory type device having cast iron shoes with projections for decortication of groundnut pods. It consist of frame, handle, oscillating arm and sieve with oblong hole. It is operated by a woman worker in sitting posture for which a stool is provided on a wooden platform. The pods are fed in batches of nearly 1.5 kg i.e. up to half of its hopper capacity so that oscillating arm can easily be operated. For proper decortication, the shoes, which are mounted on oscillating arm need to be adjusted. The women workers prefer the sitting type groundnut decorticator due to its low requirement of force and less cardiac cost.
