Description

A kind of rapeseed oil production preparation method and production method

technical field

The invention relates to the field of rapeseed processing, in particular to a preparation method and production method of rapeseed oil.

Background technique

Rapeseed is the seed of rapeseed, a cruciferous crop. The siliques of rapeseed are long, have many pods, and the grains are full. Rapeseed has a high oil content and is one of the main oil crops in China. Before the rapeseed is pressed and leached into rapeseed oil, it is usually necessary to screen out the lighter foreign matter and metal foreign matter mixed between the rapeseeds, so those skilled in the related art also carry out the process of screening the rapeseed. Lots of optimizations.

For a more accurate comparison, the Chinese patent with publication number CN213612497U discloses a rapeseed oil processing and impurity removal equipment; The impurities in the rapeseed are removed, and the first step of impurity removal is carried out. When the drum is turned over to the side of the screen, the rapeseed falls, and the light impurities in the rapeseed are sucked into one side of the first filter by the action of the first negative pressure fan. On the side, the rapeseed stays outside, and then lifts through the support plate to shake off the rapeseed from the first filter for the second impurity removal.

However, the above-mentioned rapeseed oil processing and impurity removal equipment still has the following deficiencies in the actual use process: 1. The drum can only remove impurities from the rapeseed oil by rolling, which is relatively simple, and the inside of the drum is The larger impurities screened out are difficult to be discharged outside in time, resulting in poor screening and impurity removal effect of the drum.

2. The metal foreign matter in the rapeseed cannot be screened out. If the rapeseed that has been removed from the above comparison documents is no longer magnetically separated, the metal foreign matter between the rapeseeds will easily cause damage to the subsequent oil extraction equipment. Damage will also reduce the quality of rapeseed after forming rapeseed oil; if the rapeseed processed by the above reference file is subjected to magnetic separation, the efficiency and effect of removing impurities from rapeseed oil will be reduced.

Therefore, under the viewpoint stated above, there is still room for improvement in the technical means of screening rapeseed and removing impurities before producing rapeseed oil in the prior art.

Embodiment two:

Continuing to refer to Fig. 4 and Fig. 5, on the basis of Embodiment 1, it can be seen from the technical solution disclosed above that the arc-shaped plate 84 is in a state of shaking up and down, and the arc-shaped plate 84 in the state of shaking is not conducive to Add raw materials to its upper end, so, in order to facilitate the addition of rapeseed raw materials, a feeding unit 87 is provided at the upper end of the screening rotating rod 81; specifically, the feeding unit 87 includes a screening screen 870, a feeding cylinder 871, a feeding Bucket 872, mounting ring 873, stirring upper plate 874, scraper 875, reinforcing ring 876 and reinforcing connecting plate 877.
