Background:
In the Indian subcontinent, pulses are mostly consumed after dehusking and splitting, in form of dal. During traditional cottage scale pulse milling, grains are soaked and sundried to loosen the grip of the seed coat over cotyledons, followed by milling in hand-operated stone chakkies. The capacity of stone chakkies is low and the husk is removed manually using a hand winnower (Soop). This involves drudgery to rural/farm women who usually perform processing operations:
Technology Details:
IIPR Dal Chakki comprises the feed hopper, vertical rubber-steel disk mechanism (chakki) and cyclone separator helps in dehusking and splitting of pretreated pulse grains. From the hopper, grains fall on the feeding auger which allows uniform feeding to the chakki. Dehusking and splitting take place simultaneously between stationary rubber and rotating steel disks. Husk and small cotyledon particles are removed from the milled product and collected in a gunny bag with help of a cyclone separator. Driven by 1.5 hp single phase motor IIPR Dal Chakki and gives the capacity of 75-125 kg/h for different pulses.
