Abstract: Bulk rough rice after drying consists of sound whole kernels, immature kernels, empty kernels, damaged kernels, hulled kernels and foreign materials such as straw, weed seed and dust. Fine cleaning of rough rice is an important step after drying to improve rough rice quality and to minimize quality deterioration of rough rice during storage. We developed a system for fine cleaning of rough rice. The system consists of a wind separator, gravity separator and indented cylinder separator. The wind separator removes straw, weed seed, dust and empty kernels by means of an air stream. The gravity separator discharges four streams of material: a mixture of sound whole kernels and hulled kernels; good rough rice product (mostly sound whole kernels); a mixture of sound whole kernels, damaged kernels and immature kernels, which is returned through the wind separator and gravity separator to achieve a complete separation; and a mixture of damaged kernels, immature kernels and empty kernels that is removed from the line. The indented cylinder separator removes hulled kernels from the mixture of sound whole kernels and hulled kernels discharged from the gravity separator. The sound whole kernels separated by the indented cylinder separator are mixed with the good rough rice product from the gravity separator. The fine cleaning system developed in this study enables separation and removal of immature kernels, empty kernels, damaged kernels and hulled kernels and therefore improvement in rough rice quality. The fine cleaning system has been in practical use in Japan.
