Abstract

The invention discloses a rapeseed oil hydration degumming method. The method comprises the following steps: heating raw oil of rapeseed oil, which is obtained by performing filtration to remove the residual cake meal, to 80-90 DEG C, storing the heated raw oil in an oil storage tank, and keeping the oil temperature at 80-90 DEG C; preparing a saline solution of 10-15 wt%, heating the saline solution to 80-90 DEG C, storing the heated saline solution in a saline solution tank, and keeping the saline solution temperature at 80-90 DEG C; delivering the raw oil in the oil storage tank to a hydration storage tank at the speed of 0.01-0.03m / s through an oil delivery pipe, adding the saline solution in the saline solution tank to the center of the oil delivery pipe which is 4.0-5.0m away from the hydration storage tank, allowing the raw oil and saline solution to be mixed, and enabling the mixture of the raw oil and saline solution to continuously flow into the hydration storage tank, wherein the speed of addition of the saline solution into the oil delivery pipe is 0.01-0.03m / s; and performing centrifugal separation on the mixture of the raw oil and saline solution in the hydration storage tank to remove gum deposits, thereby obtaining hydration-degummed oil. According to the rapeseed oil hydration degumming method, the saline solution is added to the center of the oil delivery pipe, so the saline solution and oil are uniformly mixed in the pipe, thereby greatly enhancing the hydration efficiency, shortening the hydration time, and greatly reducing the content of phospholipid in the hydration-degummed rapeseed oil.

Description

technical field [0001] The invention relates to a refining process of rapeseed oil, in particular to a hydration and degumming process of rapeseed oil. Background technique [0002] Rapeseed oil is the main edible oil in my country. It is obtained by refining the crude oil obtained from rapeseed by removing impurities, smashing embryos, steaming and frying, and pressing, or by refining the crude oil obtained by removing impurities, frying and pressing. Therefore, hydration and degumming is an important process in rapeseed oil refining, and colloidal impurities such as phospholipids in rapeseed oil can be removed by hydration and degumming. [0003] Hydration degumming is a kind of degumming method in which a certain amount of water (or an aqueous solution of acid, alkali and salt) is added to the crude oil by using the hydrophilicity of peptizing impurities such as phospholipids, so that the peptizing impurities in it absorb water, coagulate and settle. . In the process of ...
