A kind of rapeseed oil sedimentation tank

Abstract

The embodiment of the invention discloses a rapeseed oil sedimentation tank, which includes a sedimentation tank body, a pure oil discharge pipe is provided on one side of the top of the sedimentation tank body and an impurity outlet is provided on the other side of the bottom, and the inner cavity of the sedimentation tank body is The top is fixed with a filter inner cylinder by a bracket, the top of the filter inner cylinder is provided with a feed pipe and the bottom is provided with a discharge port, the inside of the filter inner cylinder is provided with a preliminary filtering mechanism, and the impurity outlet is connected to a screw feeder , the outlet end of the screw feeder is connected to a secondary filtration recovery mechanism. Through the setting of the secondary filtration recovery mechanism and the return pipe, the present invention has a better filtering effect on rapeseed oil, greatly improves the purification rate of rapeseed oil, and does not cause waste of rapeseed oil. The whole device filters and scrapes impurities The setting can speed up the precipitation of impurities in the rapeseed oil, and can also obtain pure rapeseed oil.

Description

technical field [0001] The embodiment of the present invention relates to the field of rapeseed oil processing, in particular to a rapeseed oil sedimentation tank. Background technique [0002] Rapeseed oil is what we commonly call rapeseed oil, also called coriander oil. It is a transparent or translucent liquid obtained by pressing the seeds of Brassica cruciferae, which is rapeseed. The human body has a high absorption rate of rapeseed oil, which can be Up to 99%, unsaturated fatty acids such as linoleic acid and vitamin E and other nutrients contained in rapeseed oil can be well absorbed by the body, and have certain effects of softening blood vessels and delaying aging. The freshly squeezed rapeseed oil also contains rapeseed oil cake residue and some other granular impurities, which will affect the quality and storage time of the rapeseed oil, so it needs to be filtered after the rapeseed oil is pressed. [0003] In the prior art, a filter structure is generally insta...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, a filter structure is generally installed in the sedimentation tank to assist the precipitation of rapeseed oil and the discharge of pure rapeseed oil, but the disadvantage is that there are still more rapeseed oil in the filtered impurities. This requires secondary treatment, resulting in an increase in processing costs, or directly discharged with impurities, resulting in waste of rapeseed oil
