Abstract
The invention discloses a rapeseed oil washing method. According to the rapeseed oil washing method, a saline solution at the temperature of 80-90 DEG C is added into crude oil of rapeseed oil processed in a degumming step at the temperature of 70-80 DEG C to perform stirring and washing for one time, then distilled water at the temperature of 80-90 DEG C is added into the crude oil to perform stirring and washing for one time, water is repeatedly added for 1-2 times to wash the crude oil, and undissolved substance contained in the degummed crude oil can be effectively removed to obtain a finished oil product with small impurity content.
Description
Technical field
The present invention relates to fundamentals field.
Background technology
Rapeseed oil squeezes by the seed of rape the liquid obtained, and removing after the undesirable substance such as phosphatide, erucic acid through refining further becomes edible oil, and its cholesterol level is lower, warm in nature, easily absorbs, and is one of main edible oil of China, suitable for all ages.
The producing process of current rapeseed oil generally includes removal of impurities, fries the processes such as seed, squeezing, refining, wherein the process of refining is mainly the process phosphatide in thick for rapeseed oil oil and other various insoluble impurities removed, generally need first through chemistry or physics remove the insolubless such as phosphatide, namely come unstuck, again the thick oil after coming unstuck is carried out washing, dry, namely obtain processed oil after completing this process.
Summary of the invention
The object of the present invention is to provide a kind of insolubles can effectively removed in the thick oil after coming unstuck, obtain the method for washing of the rapeseed oil of the few finished product of foreign matter content.
The present invention is achieved through the following technical solutions above-mentioned purpose:
Will through squeezing, slagging-off, the thick oil temperature of the rapeseed oil obtained after coming unstuck remains 70 ~ 80 DEG C, adding temperature is wherein that the salt solution of 80 ~ 90 DEG C carries out agitator treating 1 time, the mass concentration of described salt solution is 20% ~ 30%, the quality added is 5% ~ 10% of described thick oil quality, thereafter adding temperature is again that the distilled water of 80 ~ 90 DEG C carries out agitator treating 1 time, repeat to add water 1 ~ 2 time, first amount of water and later each amount of water are 15% ~ 20% of thick oil quality, the speed of the stirring described in this step is all 20 ~ 30rpm, after completing said process, thick oily standing separation is gone out the settling of bottom.
A kind of preferred embodiment of the present invention is: the mass concentration of described salt solution is 25%.
Another kind of preferred embodiment of the present invention is: the quality that described salt solution adds is 8% of described thick oil quality.
The present invention effectively can remove the insolubles in the thick oil after coming unstuck, and obtains the method for washing of the rapeseed oil of the few finished product of foreign matter content.
Embodiment
Embodiment 1
