Description

Rapeseed oil production and preparation method
Technical Field
The invention relates to the field of rapeseed processing, in particular to a rapeseed oil production and preparation mode and a production method.
Background
The rapeseeds are seeds of brassicaceae crop rapes, the pod fruits of the rapes are longer, the pod is more, and the grain is full. The oil content in the rapeseeds is higher, and the rapeseeds are one of main oil crops in China. Since the seeds generally need to be screened out of lighter foreign materials such as straw and metallic foreign materials mixed between the seeds before the seeds are pressed and leached into the seeds, a lot of optimization is performed on the screening process of the seeds by those skilled in the related art.
In order to perform more accurate comparison, for example, chinese patent publication No. CN213612497U discloses a rapeseed oil processing and impurity removing device, which is characterized in that when in use, rapeseeds pass through a screen of a roller, larger impurities in the rapeseeds are removed, the first step of impurity removal is performed, when the roller is turned over to the screen to face downwards, the rapeseeds fall down, under the action of a first negative pressure fan, light impurities in the rapeseeds are sucked into one side of the first screen, the rapeseeds are left outside, and then the rapeseeds are shaken off from the first screen for the second time by lifting through a supporting plate.
However, the rapeseed oil processing impurity removal equipment has the following defects that 1, the roller can remove impurities from rapeseed oil only in a rolling mode, the mode is single, and the screened larger impurities in the roller are difficult to timely discharge outwards, so that the screening impurity removal effect of the roller is poor.
2. The method has the advantages that the metallic foreign matters in rapeseeds cannot be screened out, if the rapeseeds subjected to the impurity removal of the comparison file are not subjected to magnetic separation, the metallic foreign matters among the rapeseeds are easy to damage subsequent oil pressing equipment, the quality of rapeseeds after the rapeseeds are formed is also reduced, and if the rapeseeds subjected to the impurity removal of the comparison file are subjected to magnetic separation, the efficiency and the effect of removing the impurities of the rapeseeds are reduced.
Therefore, under the above stated viewpoints, there is room for improvement in the prior art for screening and removing impurities from rapeseed before the production of rapeseed oil.
