Abstract
The invention provides a refining method for producing rice bran oil by utilizing rice bran with low cost and high essential oil acquisition rate. The invention adopts the technical scheme that: water is blended in crude oil, and when phospholipids and water are combined into floccule, a precipitation and separation method is adopted, wherein blended water is 2% of the weight of the crude oil, water blending time is 10 minutes, oil temperature during water blending is 40 DEG C, water temperature is 35 DEG C, stirring speed before and after water blending is 50r/min, and the stirring speed during water blending is 20r/min. The refining method disclosed by the invention effectively improves acquisition rate and quality of essential oil, has low cost and good using effect, saves time and labour, is convenient to use and is applicable to popularization and application.
Description
Technical field:
The present invention relates to a kind of process technology of edible oil, especially a kind of method of refining that utilizes rice bran to produce rice bran oil.
Background technology:
At present, at oil processing industry, usually adopt the method for deposition press filtration or alkali refining that crude oil is refined into edible oil, not only cost is high, and it is low that essential oil obtains rate, and oil is relatively poor, and some also residual harmful substance endangers the healthy of consumer.
Summary of the invention
The object of the invention is exactly the defective that exists to prior art, provides a kind of with low cost, essential oil to obtain the high rice bran that utilizes of rate and produce the method for refining of rice bran oil.Its technical scheme is: be that water mixing is stirred in crude oil, when phosphatide combines to be the method that the floccule post precipitation separates with water.Watering quantity is 2% of a crude oil weight, and the water mixing time is 10 minutes, and the oil temperature is 40 degrees centigrade during water mixing, and water temperature is 35 degrees centigrade.Before the water mixing with water mixing after mixing speed be that per minute 50 changes, the mixing speed during water mixing is that per minute 20 changes.
The present invention effectively raises the rate of obtaining and the quality of essential oil, and is with low cost, time saving and energy saving, easy to use effective, is fit to generally promote the use of.
The specific embodiment
A kind of with low cost, essential oil is obtained the high rice bran that utilizes of rate and is produced the method for refining of rice bran oil, is that water mixing is stirred in crude oil, when phosphatide combines to be the method that the floccule post precipitation separates with water.Watering quantity is 2% of a crude oil weight, and the water mixing time is 10 minutes, and the oil temperature is 40 degrees centigrade during water mixing, and water temperature is 35 degrees centigrade.Before the water mixing with water mixing after mixing speed be that per minute 50 changes, the mixing speed during water mixing is that per minute 20 changes.
Send into fining pot after the crude oil of squeezing out sieved, the mixer that changes with per minute 50 stirs, and stirs 15 minutes; When the oily temperature drop to 40 degree centigrade, mixer speed changes 20 into is changeed, at this moment; Be sprinkled upon 35 degrees centigrade water uniformly slowly and mix on the pasta in the oil, watering quantity is 2% of a crude oil weight, and the water mixing time was controlled at 10 minutes; Accomplish rear stirrer speed and revert to per minute 50 commentaries on classics, continue to stir 20 minutes, stop then stirring; Staticly settled 12 hours, and can isolate the dregs of fat of deposition, essential oil is sent into oil storage tank.
The present invention effectively raises the rate of obtaining and the quality of essential oil, and is with low cost, time saving and energy saving, easy to use effective, is fit to generally promote the use of.The rice bran oil that uses the present invention to produce detects through Dongying City grain and oil inspection center, and acid value is: 1.02, and moisture: 0.17%, assorted matter: 0.02%; Oil is heated to 280 degrees centigrade, and oil colours is constant, and no precipitate does not have any arsenide and mercuride etc., meets country-level edible oil standard.
