Problems solved by technology

[0003] In the prior art, refining is carried out by alkaline washing, and the soap formed by alkali and acid in the oil is used to absorb the pigment in the oil to improve the appearance of the rapeseed oil. This method consumes a lot of fuel and increases the economic cost. In addition, the refined rapeseed oil also The soluble impurities cannot be completely removed, and the removal effect of colloids such as phospholipids is poor, which limits the development of rapeseed oil processing technology

Embodiment 1

[0029] see figure 1 , the rapeseed oil refining device of the present invention, the rapeseed oil passes through the pretreatment equipment 1, the microwave machine 2 can carry out microwave treatment, and then passes through the filter screen 3 to obtain the substance A, and then under the action of the degumming equipment 4 and the temperature controller 5, realize Degumming, and then through the centrifuge 6 to obtain the supernatant B, only need to add 50% sodium carbonate solution, activated clay, and distilled water step by step in the integrated device 7, to realize the deacidification, decolorization, and water washing processes, and finally through the vacuum Drier 8 dries to obtain refined rapeseed oil.

[0030] A kind of rapeseed oil refining method of the present embodiment, comprises the following steps:

[0031] Step 1, pretreatment: place the rapeseed oil at a temperature of 2°C, let it stand for 50 minutes, then perform microwave treatment, and then

[0032] ...

Embodiment 2

[0044] A method for refining rapeseed oil, comprising the following steps:

[0045] Step 1, pretreatment: put the rapeseed oil at a temperature of 2°C, let it stand for 50 minutes, then perform microwave treatment, and then filter to remove impurities to obtain substance A;

[0046] Step 2, degumming: heat up the substance A obtained in step 1 to 30°C, stir at a speed of 65r / min, and stir for 40min, then add tartaric acid, heat up to 40°C, continue to stir for 30min, stir at a speed of 50r / min, then add phosphoric acid, continue Stir for 45min at a stirring speed of 35r / min, then centrifuge to obtain supernatant B;

[0047] Step 3, deacidification: adding the supernatant B into the sodium carbonate solution with a mass fraction of 50%, stirring for 30 minutes at a stirring speed of 35r / min, then adding it to a centrifuge for centrifugation at a centrifugation time of 35min and a centrifugal speed of 40r / min, Substance C is obtained;

[0048] Step 4, decolorization: Stir the ...

Embodiment 3

[0057] A method for refining rapeseed oil, comprising the following steps:

[0058] Step 1, pretreatment: place the rapeseed oil at a temperature of 2°C, let it stand for 50 minutes, then perform microwave treatment, and then

[0059] Filter again to remove impurities to obtain substance A;

[0060] Step 2, degumming: heat up the substance A obtained in step 1 to 30°C, stir at a speed of 80r / min, and stir for 40min, then add tartaric acid, heat up to 40°C, continue to stir for 30min, stir at a speed of 70r / min, then add phosphoric acid, continue Stir for 45min at a stirring speed of 50r / min, then centrifuge to obtain supernatant B;

[0061] Step 3, deacidification: the supernatant B is added to the sodium carbonate solution with a mass fraction of 50%, the stirring time is 30min, and the stirring speed is 50r / min, and then added to the centrifuge for centrifugation, the centrifugation time is 35min, and the centrifugal speed is 40r / min. Substance C is obtained;

Abstract

The invention discloses a refining method of rapeseed oil. The refining method comprises the following steps: step1, pre-treating: putting the rapeseed oil into an environment with the temperature of1 to 3 DEG C and standing for 45 to 55min; then carrying out microwave treatment and filtering to remove impurities, so as to obtain a substance A; step 2, degumming: raising the temperature of the substance A obtained by step 1 to 25 to 35 DEG C under the conditions that the stirring speed is 65 to 75r / min and the stirring time is 35 to 45min; then adding tartaric acid. According to the refiningmethod of the rapeseed oil, disclosed by the invention, an alkali washing manner is not adopted and oil consumption is less, so that the economic cost is reduced; in a degumming process, soluble impurities can be completely removed; meanwhile, the removing effect of colloids including phospholipid and the like is good and the refining method has relatively high utilization value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of rapeseed oil processing, in particular to a method for refining rapeseed oil. Background technique [0002] Rapeseed oil is what we commonly call rapeseed oil, also known as rapeseed oil, coriander oil, canola oil, sesame oil, and canola oil. It is a kind of edible oil squeezed out of rapeseed. It is one of the main edible oils in my country. In the Yangtze River Basin, Southwest, Northwest and other places, the output ranks first in the world. The human body has a high absorption rate of rapeseed oil, which can reach 99%. Therefore, the unsaturated fatty acids such as linoleic acid and vitamin E and other nutrients contained in it can It is well absorbed by the body and has a certain effect of softening blood vessels and delaying aging. From the production process, it can be divided into pressed rapeseed oil and leached rapeseed oil. According to whether the raw material is genetically modified, it can be ...
