Detection sorting device and method for rice material

Abstract

The invention provides a detection sorting device for a rice material. The detection sorting device is applied to sorting of transparent rice, white belly rice, pale yellow rice, deep yellow rice, and dark color foreign matter. The detection sorting device comprises a light source including the blue light spectrum and a blue light source which are arranged on the two sides of the rice material to be sorted respectively, and cameras for receiving light source signals are arranged on the two sides of the rice material respectively. The camera at the side with the light source including the blue light spectrum is used for detecting reflected and transmitted light source signals and blue light signals, wherein the light source signals and the blue light signals include the blue light spectrum. The camera on the side with the blue light source is used for detecting reflected and transmitted blue light signals and while signals. Sorting modes are configured according to the requirement for sorting the yellow rice, the requirement for classifying the transparent rice and the white belly rice and the requirement for commonly sorting the yellow rice and white rice. The invention further provides a sorting method. The detection sorting device and method for the rice material have the advantages that brought-out white belly rice is reduced, the pale yellow selecting performance is improved, the three different demands for sorting the yellow rice, the requirement for classifying the transparent rice and the white belly rice and the requirement for commonly sorting the yellow rice and white rice are met at the same time, the sorting adaptability is improved, and larger economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of photoelectric separation, relates to a scheme of color separation and detection, and is used for separation of heterochromatic grain impurities in rice materials. Background technique [0002] Rice usually includes transparent rice, white belly rice, light yellow rice, dark yellow rice, and dark foreign matter (stones, etc.). The sorting of rice mainly includes three requirements: yellow selection, transparent and white belly classification, and yellow and white selection. Among them, choosing yellow is to keep transparent rice and white belly rice in the finished product, and remove light yellow rice, dark yellow rice, and dark foreign matter. Divided into two grades of finished products, the same selection of yellow and white means that the finished product retains transparent rice, and removes belly white rice, light yellow rice, dark yellow rice, and dark foreign matter.

Problems solved by technology

However, this detection scheme can only ensure that the effect of selecting yellow rice is equivalent to that of heterochromatic grain mode for rice materials, that is, when the effect of selecting light yellow rice is the same, the misselection of transparent rice is equivalent.

For a certain type of rice, the effect of selecting yellow rice may be worse than the effect of selecting yellow rice with the same selection of light path as mentioned in the above example.
