Abstract

The performance of paddy and rice separator was theoretically and experimentally investigated as a function of change in separator sieve angle, paddy moisture content and feeding ratios. The separator performance was evaluated in terms of separator productivity, crack percentage, separator efficiency and energy requirements. The theoretical analyses reveal that the optimum sieve speed of 0.5 m/sec. (200 rpm) is recommended to prevent riding of material on the sieve surface. The experimental results reveal that the separator performance was in the optimum region under the following conditions:

Sieve angle of 15 deg.
Paddy moisture content of 14%.
Feeding ratio of 0.80

Main Subjects

Processing Engineering of Agricultural Products
