摘要

Millets, nutritious small cereal grains with enormous health benefits, are grown across the world for food and fodder. Due to the typical structure, hardness and small size of grains, dehusking of millets has remained as a constraint. The present investigation deals with the performance evaluation of a low cost table top centrifugal dehuller that was developed. Dehulling experiments were conducted for five millets viz. foxtail, little, proso, kodo, and barnyard millets at three moisture contents (11.1, 13.6 & 16.2% db), and three dehulling speeds (5,000, 5,500 & 6,000 rpm). The moisture content of grains had a significant effect on dehulling performance compared to dehulling speed which had less or negligible effect at times. The highest average dehulling efficiency obtained for foxtail, little and proso millets was 92.7, 91 and 93.5%, respectively, with 13.6% (db) grain moisture content and a dehulling speed of 5,500 rpm. For kodo and barnyard millets, the highest average dehulling efficiency was 80.9% and 74.4%, respectively at 11.1% (db) moisture content and a dehulling speed of 6,000 rpm. For the same experimental combination, the percentage of broken was less than 5% for foxtail, little and proso millets, while for kodo and barnyard millets, it was 5.7 and 9.2%, respectively. The average un-dehulled grain percentage for foxtail, little, proso, kodo and barnyard was 2.4, 5.7, 2.3, 14.2 and 18.1%, respectively. The approximate cost for converting one kg of millet in to rice is about INR 0.97 ($0.01).
