Rapeseed is the seed of brassica napus, a crucifer crop, called brassica seed, which has long pod bearing, more pod bearing and full grain. The rapeseed is one of main oil crops and honey source crops in China, the kernel of the rapeseed is one of main varieties of oil and fat preparation raw materials, and after the rapeseed is harvested, impurities such as broken leaves, epidermis and the like are inevitably mixed in the rapeseed, so the rapeseed needs to be screened and removed before entering an oil press device.

Therefore, the research and development of the rapeseed fine-selection device is one of the technologies which are urgently to be solved in the industry development. Patent CN 210045580U discloses a sesame classificator for sesame processing, which integrates the cooperation of air blowing and a screen mesh to separate larger impurities and smaller dust, thereby achieving the purpose of good classificator effect; the patent CN 108543710A discloses an agricultural rapeseed screening machine, and the screening frame moves left and right to carry out secondary screening on rapeseeds, so that the screening effect of the rapeseeds is improved.

Based on the research and development, the invention develops the oil raw material selection device which can automatically select, dry, facilitate collection and thoroughly screen impurities, and the application of the oil raw material selection device in selecting vegetable oil such as rapeseed, sesame and the like.
