GROUNDNUT DECORTICATOR
Function
For separating kernels from groundnut pods.
Brief description
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.
Working
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.
Benefits
The productivity of workers increased tremendously than traditional practice apart from safety of workers.
The reduction of drudgery with the equipment per kg of pods decorticated is to the tune of 74 and 79% in case of standing and sitting type decorticator respectively.

GROUNDNUT STRIPPER
Function
For stripping on groundnut pods.
Brief description
The groundnut stripper consists of a square frame of vertical legs and a horizontal strip of expanded metal fixed on each side of the frame in the form of comb. The stripping of the pods is accomplished by drawing a handful of vines across the comb with a slight force. The structure facilitates its use by four women simultaneously. A small adjustable stool was fabricated for the operator to sit and perform the stripping operation.
Working
The height of the stool can be adjusted from 28-40 cm. this design eliminates knee pain and numbness while stripping in sitting posture at ground level. The frame was provided with telescopic support legs which enable the subjects to adjust the height of the frame from the ground level to suit their convenience to avoid postural discomfort. Also the hitting of the elbow against the abdomen while stripping is eliminated
Benefits
Higher output i.e. 350 kg of pods/day can be obtained as against 200 kg in case of conventional stripping.
Squatting posture is avoided which minimizes stress at knee.

ROTATORY MAIZE SHELLER
Function
For shelling maize from dehusked cob.
Brief description
It is a manually operated equipment consisting of a frame, a flywheel, a hopper and three s helling
gears.
Working
With one hand a person operates the equipment whereas cobs are fed by the other hand one by one. The shelled cobs come out through the port on other side.
Benefits
Output is very high and the equipment is suitable for farmers growing large quantity of maize
The chances of injury to fingers are eliminated thus making the operation safer for workers.

PEDAL OPERATED PADDY THRESHER
Function
For threshing of paddy.
Brief description
This thresher consists of a cylinder with wooden/aluminum strips. The wire loops are embedded/
welded on these strips. The cylinder is given a rotary motion from the foot pedal through a power
transmission system. The paddy bundles are threshed with hold method.
Benefits
It helps to reduce the drudgery involved in paddy threshing operation as bending posture is
avoided and arms are not to be raised for above shoulder height as in case of traditional
method i.e. beating on a platform/stone.

HANGING TYPE GRAIN CLEANER
Function
For separating impurities like stubbles, chaff, dirt and broken received with grain after threshing.
Brief description
It consists of main frame, grading screen, draper rod, rubber grip over handle, shutter etc. Four ropes are tied on the hooks provided on main frame of cleaner and hanged on any elevated point or hooksattached to the ceiling.
Working
It is operated in oscillating mode. The handle height of cleaner from ground should be at waist height of operator. Based on the size of grain, screen may be selected. Slow movement of cleaner is required after pouring grain on top of screen so that grain goes slowly down the cleaner box and chaff/ stubbles are remained on top of screen. After collecting the chaff from top of screen, gentle movement of cleaner is done to remove dirt, broken and finer chaff etc. present in the grain. Thereafter, it is taken out in a bag that is hanged on a sack holder by opening shutter of cleaner.
Benefits
The productivity of the worker increased more than four times as compared to traditional thereby reducing drudgery.
