High-quality and environment-friendly rapeseed oil refining method as well as rapeseed high-quality refining device used thereby

Abstract

The invention discloses a high-quality and environment-friendly rapeseed oil refining method as well as a rapeseed high-quality refining device used thereby. In order to overcome the defects that theexisting rapeseed oil refining technology and device adopt alkali refining and have high cost and bad effect, the squeezed crude rapeseed oil is filtered and precipitated and is then input into the rapeseed oil high-quality refining device, the temperature is increased to 150 DEG C, heat preservation is conducted for 10 minutes, decoloring and peculiar smell removal are conducted, and 400-mesh vibration filtration is conducted to obtain the pure clear rapeseed oil; and a phosphorus-removing and acid-removing cavity is formed outside a rapeseed oil cavity of the rapeseed oil high-quality refining device, the phosphorus-removing and acid-removing cavity is connected with a steam input mechanism, and a heat transfer wall is arranged between the rapeseed oil cavity and the phosphorus-removingand acid-removing cavity. The device is mainly applied to high-quality and environment-friendly refining of the rapeseed oil and does to need to add sodium carbonate to perform alkali refining, the process is simplified and environment-friendly, the refining cost is low, the efficiency is high, the effect is good, the obtained rapeseed oil has pure color and taste, aftertaste is avoided after storage, and the discharge object is easy to treat to reach the standard.

Description

Technical field [0001] The invention relates to a method and device for refining rapeseed oil, in particular to a method for refining rapeseed oil with high quality and environmental protection and a high-quality refining device for rapeseed oil used in the method. Background technique [0002] Rapeseed oil is abbreviated as "rapeseed oil", which is mainly taken from the seeds of cabbage-type rape and cabbage-type oil, containing 22-49% oil, 21-27% protein, and about 1% phospholipid. The oleic acid content of the unsaturated fatty acids in rapeseed oil is second only to olive oil, with an average content of about 61%. In addition, the content of oleic acid and linoleic acid that are beneficial to the human body contained in rapeseed oil ranks first among various vegetable oils. [0003] The crude oil of rapeseed oil is yellowish and greenish. It is an oil with a particularly high erucic acid content. It has a unique and strong odor (caused by glucosinolate) and needs further refin...

AI Technical Summary

Problems solved by technology

[0005] The deficiencies of existing rapeseed oil crude oil refining technology and devices are that it is necessary to add substances such as edible alkali to carry out alkali refining when refining rapeseed oil, because the substances added in processes such as alkali refining make the color of the obtained rapeseed oil 1. The taste is not pure enough, there will be aftertaste during storage, the refining process is difficult to meet the high-quality and environmental protection standards, and the refining cost is high, the efficiency is low, and the effect and benefit are poor

[0006] There is no report in the existing literature that can better overcome the above shortcomings
