ciency ofDecomatic was 8.4% and the . . Engineering was 8.7%. The results with broad beanshowed excessive damage to the seed by both machines. There were also large variations among the efciencies from sample to sample; thus, it was concluded that in these type of machines the treatment of the grain is not uniform. 3.5 Husk Separation and Grading Husks are separated by aspiration and sold as animal feed. Some ne brokens are present in the husk and, if separated, can make available an extra quantity for human consumption. Grading adds to the quality of product by separating the dehusked unsplit grains (gota),whole grains, brokens, and dal in two grades. However, problems in separation of gotaand whole grains owing to their same size and shape, leads to repeated exposure of grainsto the machine and breakage during milling. new method of separating whole anddecorticated grain based on their bouncing properties has been reported (. succession of four hard surfaces is used to bounce the whole seed and the decorticated seed. 6% efciency of separation was established in the laboratory trials for pigeon peas. The mixture of brokens and husk is separated from the dehusked pulses and splits by using suction fan or blower and the mixture is used as animal feed. To separate thebrokens for human consumption, the use of specic gravity separator is advocated.This machine gives separation of about 5% brokens available in the mixture. The ma-chine is supplied with three, four, and ve fans, with capacity ranging from 6 to 4 kg/. 3.5.1 Polishing Whole pulses, such as pea, black gram, green gram, and splits (dal), are polished for value- adding. Some consumers prefer unpolished dal, whereas others need dal with attractivecolor (polished dal). Accordingly, dal is polished in different ways such as nylon polish, oilwater polish, color polish, and so on. 3.5.1.1 Removal of Powder and Dust The cylindrical roller mounted with hard rubber, leather, or emery cone polisher, and roller
