Abstract
Description
Technical Field
[0001] This utility model relates to the field of peanut kernel quality grading and screening technology, and in particular to a peanut kernel grading and screening device. Background Technology
[0002] The quality of peanut kernels directly determines the quality of the processed product. Therefore, it is necessary to use a peanut kernel quality grading and screening device to separate peanut kernels of different qualities. Traditional peanut kernel quality grading and screening devices mainly consist of a feeding system, a detection system, a control system, and a rejection system. Peanut kernels enter the device through the top hopper, and the device then uses the color sorting principle to screen peanut kernels of different qualities. Unqualified peanut kernels are blown out, while qualified ones are retained, thereby achieving the purpose of grading.
[0003] However, when screening peanut kernels, the outer skin of the peanut kernels is easy to fall off and mix with the kernels, which affects the screening effect. At the same time, manual feeding is required when screening peanut kernels, which greatly reduces the screening efficiency. Therefore, it is necessary to design a peanut kernel grading and screening device. Utility Model Content
