new technique of pneumatic polishing of rice has been conceived
in this study, similar to that of commercial jet polishing of metal surfaces.
In jet polishing of metal surfaces, abrasive particles and pressurized
air are allowed to strike on the metal surface at high speed (Tsai,
Yan, Kuan, &Huang, 2007). High rate of frictionwith these hard abrasive
particles results very effective polishing using simplemechanism. In this
new technique of rice polishing, a modification of the jet polishing has
been tried.
