A selection method of melon seeds

Abstract

Disclosed is a fine selection method for melon seeds. Devices adopted by the fine selection method comprise a vibrating screen and a winnowing mechanism, and further comprise a conveying device and acolor-selecting mechanism. The conveying device comprises a loop-locked transparent conveyor belt. A light source facing the transparent conveyor belt is arranged below the transparent conveyor belt.A humidifying pipe is arranged above the transparent conveyor belt. The humidifying pipe communicates with a humidifying device through a pipeline. The color-selecting mechanism comprises a CCD cameralocated above the transparent conveyor belt and located on the rear side of the humidifying pipe. The side part of the transparent conveyor belt is provided with a pushing plate. The pushing plate isin driving connection with a reciprocating moving driving device. The CCD camera is in signal connection with a controlling system. The controlling system is in signal connection with a controlling device of the reciprocating moving driving device. According to the fine selection method for the melon seeds, by spraying wet air to the melon seeds, melon seeds with mildew spots and normal melon seeds are contrasted more clearly, so that identifying is conducted more easily by the color-selecting mechanism.

Description

technical field [0001] The invention relates to a sorting method of melon seeds, which belongs to the technical field of food processing. Background technique [0002] Melon seeds refer to the seeds of melons. There are many types, such as sunflower seeds, pumpkin seeds, and watermelon seeds. Melon seeds can be fried and used as snacks, and can also be used as raw materials for making pastries and protein drinks. At the same time, they are also important raw materials for oil extraction, which is a high-grade and healthy source of oil. [0003] In order to ensure the quality of fried melon seeds, it is an important link to sort melon seeds before frying. The efficiency of manual sorting is low, which cannot meet the needs of large-scale production, and then an automatic sorting melon seed material machine has been produced. The color sorter is an important equipment for melon seed sorting machines. The photoelectric color sorter using linear array CCD technology has become...

Problems solved by technology

[0004] During the harvesting and storage process of melon seeds, affected by the environment, mildew spots are likely to form on the surface of melon seeds, and the mold spots are not easy to appear after the melon seeds are dried, and are easy to be packaged with normal melon seeds to obtain finished products, resulting in low quality of finished products. Therefore, it is necessary to design a selection method for melon seeds
