Abstract

A grain sorting method and a device is provided which serves to continuously and quickly detect the appearance quality of the grains. The grain sorting device includes a feeding mechanism and a scattering mechanism where the grains are separately scattered over the surface of a conveying belt. The conveying belt serves to transfer the grains to a photographing section where they are photographed and inspected by an electric coupling device. Various parameters of the grains are calculated and the inspected results are compared with data stored in a computer. The grains are then sorted into different classifications and respectively collected by a discharging device.
