Description
Technical field
The present invention relates to oil processing field, specifically a kind of refined rice bran oil combination degumming alkali refining method.
Background technique
Beating the oil chaff that rice comes out can extract oil, this is just rice bran oil, and rice bran oil is the pair as obtained in paddy processing process
Product rice bran, a kind of Rice oil produced with squeezing method or lixiviation process, private refining rice bran oil tech is also immature at present, Japan
Sensational rice bran oil poisoning once occurred, nine divisions of China in remote antiquity one, the field great Mu city Grain Processing Corporation eats oilmill, in life
When producing rice bran oil, in order to reduce cost profit-push, low price degumming raw material is used in scouring processes, degumming effect difference is held simultaneously
It easily causes harm to the human body, as the raising and people of China's rice intensive processing industry integral level are to the battalion of oils product
The attention of health-care effect is supported, the industrial chain of rice bran oil is gradually forming, and market potential will gradually discharge, and have certain production capacity
The enterprise of scale can obtain rapidly the larger market share by technical advantage, but it is safe and non-toxic be still need the step of pursuing with
Method.
Summary of the invention
To solve the above-mentioned problems, the present invention proposes a kind of refined rice bran oil combination degumming alkali refining method.
A kind of refined rice bran oil combination degumming alkali refining method, specific step is as follows：
(1) oil stirring is thrown：By in 10 tons of Rice bran crude oil investment alkali refining tank, start uniform stirring；
(2) steam heats：Steam is opened to Rice bran crude oil and is heated to 70 DEG C；
(3) add phosphoric acid：Diluted phosphoric acid is added in Rice bran crude oil and is quickly stirred to react 15 minutes；
(4) adding sodium hydroxide：Sodium hydroxide needed for free fatty acid is totally removed is calculated according to the acid value of Rice bran crude oil
30% sodium hydroxide solution is added in amount；
(5) heating reaction：Rice bran oil is warming up to 80 DEG C, is reacted 5 minutes；
(6) add salt water：Salt water and the stirring of 500 liter of 10% concentration are added in rice bran oil, it is seen that after crystalline particle, immediately
Stop stirring；
(7) stratification：By rice bran oil stratification 6 hours or more, lower layer's soap stock is released；
(8) salt water secondary cleaning：Rice bran oil is washed two times with the salt water of oil mass 5%, soap stock is released, obtains edible vegetable oil.
The amount of sodium hydroxide in the step (3) needs to remove itself acid value, and the phosphoric acid is to have in 50 liters
30% concentration, the temperature of Rice bran crude oil is maintained at 70 DEG C when the described addition phosphoric acid.
Salt water in the step (6) is 10% concentration, the same oil temperature of the temperature of salt water, the salt water of the oil mass 5%
It is 500 liters.
The beneficial effects of the invention are as follows：Combine purification Rice bran crude oil with sodium hydroxide using phosphoric acid, physically method of refining
So that technique simplifies, equipment investment is low, and environmentally friendly, refining effect is good；Twice using salt water cleaning, Rice bran crude oil has been ensured
Internal cleaning, purity is high.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below it is right
The present invention is further described.
Embodiment：
A kind of refined rice bran oil combination degumming alkali refining method, specific step is as follows：
(1) oil stirring is thrown：By in 10 tons of Rice bran crude oil investment alkali refining tank, start uniform stirring；
(2) steam heats：Steam is opened to Rice bran crude oil and is heated to 70 DEG C；
(3) add phosphoric acid：Diluted phosphoric acid is added in Rice bran crude oil and is quickly stirred to react 15 minutes；
(4) adding sodium hydroxide：Sodium hydroxide needed for free fatty acid is totally removed is calculated according to the acid value of Rice bran crude oil
30% sodium hydroxide solution is added in amount；
(5) heating reaction：Rice bran oil is warming up to 80 DEG C, is reacted 5 minutes；
(6) add salt water：Salt water and the stirring of 500 liter of 10% concentration are added in rice bran oil, it is seen that after crystalline particle, immediately
Stop stirring；
(7) stratification：By rice bran oil stratification 6 hours or more, lower layer's soap stock is released；
(8) salt water secondary cleaning：Rice bran oil is washed two times with the salt water of oil mass 5%, soap stock is released, obtains edible vegetable oil.
The amount of sodium hydroxide in the step (3) needs to remove itself acid value, and the phosphoric acid is to have in 50 liters
30% concentration, the temperature of Rice bran crude oil is maintained at 70 DEG C when the described addition phosphoric acid.
Salt water in the step (6) is 10% concentration, the same oil temperature of the temperature of salt water, the salt water of the oil mass 5%
It is 500 liters.
Combine purification Rice bran crude oil with sodium hydroxide using phosphoric acid, physically method of refining simplifies technique, and equipment is thrown
Provide low, environmentally friendly, refining effect is good.
Twice using salt water cleaning, the cleaning inside Rice bran crude oil has been ensured, purity is high.
The grease phosphorus content of three other depickling methods, the comparative test of yield and color are resettled according to above-described embodiment,
As a result as follows：
| Method of refining | Grease phosphorus content/ppm | Yield/% | Color |
| First degumming chemical deacidification again | 150 | 65 | Kermesinus |
| First degumming physical deacidification again | 180 | 71 | Peony |
| Solvent method degumming depickling | 160 | 66 | Peony |
| Combination degumming depickling | 100 | 72 | Light red |
As a result：Using the present invention relative to other traditional depickling methods, grease phosphorus content of the present invention is low, high income, and color is inclined
It is light, purity is high.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these variation and
Improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent
Object defines.
