ing and grading of pulses is used for gota separation and dal grading. three- and four-compartment rotary sieve is used for gotaseparation and dal grading, respectively. Some manufacturers supply reciprocating-typescreen with 3- to 5-mmstroke length for gota separation and dal grading. combination of rotary screen cleaner for raw material cleaning and reciprocating screens for gota separation and dal grading is also employed by some millers. The sizeof perforations vary depending on the type of grain to be processed. The specicationsof the machine vary with the manufacturer and capacity of particular unit (see Table .These units are built in wooden or mild steel frame and are used for the separation ofgota, splits, and brokens. The dal grader receives the product from the splitting unit andgrades gota, dal in two grades, brokens, and powder. 3.7 Pulse Conditioning and Dehusking for Modern Mills conditioning unit consists of two sets of tempering bins, two pulse heating units, each having separate motorized blowers, air heat exchangers, grain-heating chambers, and feedhoppers. The temperature is controlled thermostatically. This entire unit is used for condi- tioning grain to loosen the husk. 3.8 Gota Conditioning and Splitting Unit for Modern Mills gota-conditioning unit consists of motorized blower, air heat-exchanger, gota heating chamber, and thermostatic temperature control arrangement for gota heating and oneblower for the aeration chamber, with mechanized delivery outlet for aerating gota with moist air. The unit provides the conditions necessary for treating the gota for loosening the binding of the cotyledons and minimizing the breakage during splitting. 4 DEHULLING CHARACTERISTICS The dehulling characteristic of any pulse is exhibited by the ease of dehusking and split- ting. Dehusking is measured as the percentage of the original weight that has been de- hulled. The splitting quality is reected in the percentage of whole splits obtained afterdeh
