Abstract
This invention has disclosed that one kind super-critical CO2 to extract the seed oil from Spine Grape seed, it includes the following step: (1)Crush Spine Grape seed to dry, crush to 20-50mesh, put it in the material tube of the extraction jar; (2) set up cold case temperature for extraction at - 3 - 3 Deg. C, injet the liquified CO2 into the extraction jar passing through the purify machine and the preheater, the pressure up to l5MPa- 30MPa, the temp. is 35 - 60 Deg. C and the extraction time for 4-5 hours; (3)Separate the CO2 fluid with oil which enters the separation cauldron from extracting jar, the pressure of separating cauldron I is 8MPa- 12MPa, temperature is 35 - 60 Deg. C, the pressure of separating cauldron II keeps being balanced with the way of escape, temperature keeps 35 - 55 Deg. C. Advntages: high efficiency in extracting, energy consumption is low, the products are of high quality, there is no solvent to remain, pollution-free to the environment.
Description
Technical field
The present invention relates to a kind of method of from the Vitis davidi seed, extracting seed of Radix vitis romanetii oil, especially relate to a kind of employing supercritical CO
2Abstraction technique extracts the method for seed of Radix vitis romanetii oil from the Vitis davidi seed.
Background technology
Vitis davidi (Vitis.davidii
) being distributed widely in ground such as Shaanxi, Gansu, Central China, south China and southwest, the western part in Hunan and southern mountain area have abundant wild Vitis davidi to distribute.Fruit seed content is many, and it is heavy by 4%～6% to account for grain.Contain 14%～17% grease in the Vitis davidi seed, the raisin seed oil unsaturated fatty acid content is up to 90%, and wherein linoleic acid content reaches more than 70%.Linolic acid has the effect of anti-hemostasis suppository generation, vasodilation and nourishing brain cell, and vessel softening, reducing cholesterol are had extraordinary effect, contains multiple liposoluble vitamin and mineral element in the raisin seed oil simultaneously, is a kind of high-quality natural product.
At present, extract seed oil and mostly be the organic solvent extraction method from the grape seed, this method is not only extracted long flow path, energy consumption height, low, the serious environment pollution of yield: and the quality product of extraction is relatively poor, purity is low, peculiar smell and dissolvent residual are arranged, had a strong impact on the promotion and application of raisin seed oil.
Summary of the invention
The objective of the invention is to invent that a kind of extraction efficiency height, energy consumption are low, the method for from the Vitis davidi seed, extracting seed of Radix vitis romanetii oil of good product quality, no solvent residue, environmentally safe.
The objective of the invention is to be achieved through the following technical solutions.
It comprises the steps: that (1) pulverizing with the Vitis davidi seed oven dry of cleaning, is crushed to 20～50 orders (preferred 30～40 orders), places the barrel of extraction cylinder, installs sealing-ring, screws plug; (2) extraction ice chest temperature is set to-3 ℃～3 ℃ (preferred version is 0 ℃), opens CO
2Steel cylinder, CO
2Come out from steel cylinder, enter in the ice chest through gas purifier I and liquefy, squeeze into the extraction cylinder by high-pressure pump through cleaner II, preheater I then, boost to 15MPa～30MPa, make it to become supercutical fluid and in the extraction cylinder, extract; Control extraction cylinder temperature is 35 ℃～60 ℃; 4～5 hours extraction time; (3) separation is dissolved with greasy CO
2Fluid from the extraction cylinder after decompression enters separation system, separate in separating still, the pressure of separation reactor I is 8MPa～12MPa (preferred version is 10MPa), and temperature is 35 ℃～60 ℃, the pressure of separation reactor I I keeps and way of escape balance, and temperature keeps 35 ℃～55 ℃.With this understanding, grease and CO
2Realize good separation, and emit CO from the separating still bottom
2Draw from the separating still top, enter ice chest liquefaction, recycle through cleaner I.
Advantage of the present invention is: technical process is simple, the extraction efficiency height, and product is pure, no solvent residue, environmentally safe.
