Abstract

An experimental apparatus featuring dual flat belt rubbing method was designed and constructed. An experiment was conducted to determine the torque requirement and the threshing capability of the method. Three rice varieties, i.e., Arborio (Javanica Type), Bluebonnet 50 (Indica Type) and Koshihikari (Japonica Type) were used in the experiment. The more rice panicles that were inserted between the belts gap, required more torque to thresh the grain. The torque required to thresh rice with a 1mm belt clearance was larger than that for a 2mm belt clearance. Bluebonnet 50 (Indica type), which is well known as a high shattering rice, threshed better than the other varieties. In contrast, Koshihikari (Japonica type), which is a low shattering rice, more unthreshed grains were found than threshed grains. The amount of damaged grain of Bluebonnet 50 was the lowest among other three varieties tested. The dual flat belt threshing mechanism transported the threshed grain to the rear part of the machine.
