In this paper author practised measurements on the hulling function of Centrifugal Rice Huller, giving one paddy at a time under various revolutions of the impeller.
1. The lower limit of revolution of the impeller for hulling action is about 500-1000 r. p. m., and the upper limit about 4000 r. p. m.
2. S-figured curves in fig. 1 and 3 show the relation between revolution of impeller and hulling rate of paddy.
3. Fig. 2 and 4 indicate the characteristics curves of the hulling property of paddy to given revolution of impeller.
4. Broken rice is assumed to be chiefly occured by the second impact-process.
