Abstract
The invention discloses a refining process of cannabis oil. The refining process mainly comprises the steps: removing impurities, degumming, decoloring, deodorizing and the like. In a refining process, impurities which are harmful to a human body and go against grease storage and use in oil are removed, substances which are beneficial to the health of a human body are remained, and physical and chemical characteristics are not damaged. The cannabis oil contains much linoleic acid and linolenic acid, and when the two fatty acids are deodorized, if the temperature and the time are not well held, trans-fatty acids are very easily generated in reactions. According to the refining process, through strictly controlling the temperature and the time in a refining process, the generation of the trans-fatty acids is reduced, and the cannabis oil with higher quality is obtained.
Description
Technical field
The present invention relates to a kind of refinery practice of grease, especially a kind of refinery practice of fiery sesame oil.
Background technology
Hemp Seed is again cannabis,fructus or numb benevolence, is the dry mature fruit of moraceae plants hemp.Hemp Seed contains rich in protein, unsaturated fatty acids, also has the trace element of the needed by human such as Yelkin TTS, linolenic acid, VITAMIN and calcium, iron mineral.Food have ease constipation stomach, enriching yin qi-restoratives, aid digestion, improving eyesight protects the liver, effect of getting rid of illness and lengthening one's life, and the diseases such as old man's constipation, hypertension and hypercholesterolemia had to special curative effect, and fiery fiber crops are unique oil plants that can be water-soluble.
In the refining process of fiery sesame oil, we should remove harmful in oil, be unfavorable for grease storage and the impurity using, the material at the healthy and helpful place to human body, should not destroy its physics-chem characteristic.In fire sesame oil, contain more linolic acid, linolenic acid, and these two kinds of lipid acid are in the time that deodorization is processed, bad if temperature and time is controlled, the generation trans fatty acid that can be very easy to react, greatly reduces its nutritive value and pharmaceutical use.
Therefore, to those skilled in the art, obtaining a kind of high-quality pure natural, trans fatty acid by refining, to produce few fiery sesame oil be problem demanding prompt solution.
Summary of the invention
The invention provides a kind of refinery practice of fiery sesame oil, effectively overcome deficiency of the prior art, preserve natural component and physiologically active substance in oil plant, reduced the generation of trans fatty acid.
The present invention adopts following technical scheme for achieving the above object:

(3) grease of separating from whizzer is heated to 85～95 ℃, being transported to vacuum drier is dried, after dry, 70～80% oil is heated to 100～110 ℃, enter bleaching tower decolouring, 20～30% oil is entered to size mixing tank and the gac that adds to be entered and after the tank of sizing mixing is sized mixing, is transported to bleaching tower and keeps 30～35 minutes, oil after decolouring enters leaf-type filter and filters, and is then cooled to 60～70 ℃, then filters;
(4) step 3 was processed to oil input deaerator, to remove oxygen and the moisture in oil, oil after gassing is transported to deodorizing tower after being heated to 230～240 ℃, each layer of deodorizing tower is full of oil, in the time that temperature reaches 170～180 ℃, pass into steam, the lipid acid distilling out and other fat by deodorizing tower top are reclaimed by trap condensation, processed oil condenses to 40～50 ℃, is delivered to finished pot until detect after qualified.
Impurity described in step 1 comprises saponin, hydro carbons, superoxide, free fatty acids, carbohydrate and derivative protein.
Described in step 2, the massfraction of aqueous citric acid solution is 50～60%.
Described in step 2, the massfraction of aqueous sodium hydroxide solution is 2～3%.
Described in step 4, the vacuum keep of deaerator is at 0.08～0.1MPa.
Described in step 4, the absolute pressure of deodorizing tower maintains 500～600Pa.
Described in step 4, every layer of bottom of deodorizing tower is furnished with steam jet.
The present invention has reached following beneficial effect:
1, it is not too high that the present invention has strictly controlled the temperature in deodorizing tower, avoids producing too much trans fatty acid;
2, the present invention has well controlled the residence time of grease in deodorizing tower, has reduced the destructiveness to fatty acid structure.
