geon pea. The kernel moisture contentwas progressively reduced by drying at 5 (from 1 down to approximately 4%), or progressively increased by wetting with addition of water (from 1 to about 1%). Figure 3shows that reduced moisture (6%) gives the highest dehulling efciency. When the seed was heat-treated by blowing hot air into the sample, the efciency increased progressively leveling off at 1 1C. However, it was recommended that the temperature be care- fully chosen so that the seed quality is not damaged.

The size of drying yard has no generalized correlation with the capacity of mill, and drying time ranges between 3 and 8 days. Some times thick-layer, sun-drying is fol-lowed, which results in nonuniform drying and breakage during milling. This is crucialpart in premilling treatment and needs consideration. The premilling treatment, as such,varies from miller to miller and thereby results in repeated exposure of grains to millingmachinery, adds to breakage and lowers the dal recovery. Standardization for sequence of operation, including pretreatment for each pulse crops, would help save these losses to greater extent. The hull of the matured soybean kernel is loosely attached to the cotyledons and, therefore, could be detached fairly easily in cracking of conditioned beans. 1% re-duction in bean moisture content promotes dehulling. Heat treatment of beans at 9 for 1 min breaks the bond between hulls and cotyledon. The relative humidity of the drying air is the most signicant factor affecting the level of seed coat cracks in soybean. Cracks increase with increases in drying air temperature, initial moisture content, anddrying rate, and decrease with increased nal moisture content and drying air relativehumidity. Bea
