Abstract
The invention discloses a nervonic acid extraction device, which comprises a raw oil pretreatment unit, a saturated fatty acid separation unit and a multi-level fractionation unit which are sequentially communicated; the raw oil pretreatment unit comprises a second flowmeter, a first fine filter and a first plate heat exchanger which are sequentially communicated; the saturated fatty acid separation unit comprises a first heating and stirring tank, a crystallization tank and a plate and frame filter press which are sequentially communicated, wherein the first heating and stirring tank is communicated with the first plate heat exchanger; the multi-level fractionation unit comprises a second heating and stirring tank, a first jacketed fractionation tank, a third heating and stirring tank, a second jacketed fractionation tank and a second fine filter which are sequentially communicated; the reaction conditions are easy to control, the purity of the nervonic acid obtained by separation is high, each specific device involved in the extraction device is a standard device, and extra cost is not needed, so that the extraction cost of the nervonic acid is low. The extraction device has simple structure, and short extraction period of nervonic acid.
Description
Technical Field
The invention belongs to the technical field of extraction of fatty acid in grease, and particularly relates to a nervonic acid extraction device.
Background
Nervonic Acid (NA for short), the general formula of which is C24H46O2Is a monounsaturated fatty acid having the formula: CH (CH)3(CH2)7CH＝CH(CH2)3COOH, relative molecular weight 366.63。
Nervonic acid was first found in mammalian nerve tissue and was named nervonic acid. Foreign research shows that nervonic acid is a core natural component of brain nerve cells and nerve tissues, is a specific substance which is discovered in the world so far and can promote the repair and regeneration of damaged nerve tissues, is an essential 'higher nutrient' for the growth, regeneration and maintenance of nerve cells, particularly brain cells, optic nerve cells and peripheral nerve cells, and has great effects on improving the activity degree of the brain nerves and preventing the aging of the brain nerves.
Nervonic acid is mainly used in the following fields: 1. blending oil: so that the fatty acid ratio of the fatty acid can meet the metabolic requirement of human body. Avoid the occurrence of chronic diseases such as obesity, heart disease, diabetes, hyperlipemia and the like;
2. high oleic acid edible oil: supplementing unsaturated fatty acid (MUFA) unit in the edible oil to make the mass fraction of the MUFA unit be more than or equal to 75%, so as to prevent the cholesterol oxidation of low-density lipoprotein (LDL), improve high-density lipoprotein (HDL), protect blood vessels, and prevent cerebral apoplexy and cardiovascular diseases;
3. functional edible oil: linoleic acid and linoleic acid which can not be synthesized by human bodies and unit unsaturated fatty acid (MUFA) are reasonably blended and fused to meet the functional health requirements of the human bodies, such as memory enhancement, vision improvement, prostate hyperplasia inhibition, blood fat reduction and cardiovascular and cerebrovascular disease prevention;
4. special oil for food processing: processing high-end baked food, spraying, puffing, quick-freezing, roasted food, can, seasoning packet, frying base material, baking tray and high-temperature-resistant food material, and the like;
5. functional special oleic acid: the nervonic acid is called as brain gold by the scientific community, can supplement brain nutrition, repair brain trauma and effectively prevent and treat senile dementia;
6. other fields: such as health products (cod liver oil), cosmetics (skin care oil), industrial oils (lubrication, cutting and polishing, spinning, perforating, etc.).
The existing nervonic acid mainly comes from deep sea fish oil and shark brain, and has high extraction difficulty and high cost.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides a device for extracting nervonic acid.
The technical scheme adopted by the invention is as follows: a nervonic acid extraction device comprises a raw oil pretreatment unit, a saturated fatty acid separation unit and a multi-layer fractionation unit which are sequentially communicated;
