Abstract
A CO2 supercritical method for extracting chrysalis oil is carried out by drying chrysalis in baker to water content less than 5%, crushing, putting chrysalis particles of 10-80 meshes into extractor, extracting at 15-50 deg. C for 0.5-4 hrs with CO2 flow 15-35kg/h and 10-30MPa, passing needle valve, separator and collector to obtain crude chrysalis oil, and centrifugally removing impurities to obtain final product. It's simple and cheap; it has higher oil-out rate, short production period, gentle operation condition and no residual organic solvent.
Description
Technical field
The invention relates to the manufacture method of bio oil, more particularly, the invention relates to and from silkworm chrysalis, use supercritical CO
2The method of technology extraction silkworm chrysalis oil.
Background technology
At present on grease production, need distillation heating, the easy oxidative rancidity of grease in the sepn process of conventional art extraction method, have dissolvent residual, and shortcoming such as low, the exquisite technology of milling process productive rate is loaded down with trivial details, product color is undesirable.Silkworm chrysalis oil has the good health care effect to human body, be widely used in food, medicine and other fields, yet the various shortcoming that traditional separation method exists can not satisfy human needs to silkworm chrysalis oil, and therefore the new production technique that need invent solves the many disadvantages of silkworm chrysalis oil production aspect.
Summary of the invention
Technical problem: the objective of the invention is to overcome the shortcoming of prior art, a kind of supercritical CO of using from silkworm chrysalis is provided
2Technology is produced the method for silkworm chrysalis oil.Use supercritical CO among the present invention
2Method of extraction has reached the purpose of safe extraction silkworm chrysalis oil as the technology skeleton of extraction silkworm chrysalis oil.
CO
2Critical temperature is at 37.2 ℃, and the effective constituent that can preserve more in good condition in the silkworm chrysalis is not destroyed or changes.The fluidic dissolving power is relevant with the size of its density, and the subtle change of temperature, pressure can cause the variation significantly of fluid density, thereby influences its dissolving power.So by regulating and controlling working pressure, temperature, make effective constituent obtain enrichment, extraction efficiency height, be convenient to control quality product.CO
2Nontoxic, harmless, nonflammable, viscosity is low, surface tension is low, boiling point is low, be difficult for causing environmental pollution.By direct and GC, IR, couplings such as MS, LC, can reflect the concentration of effective constituent in the Pupa bombycis extract objectively, thereby realize extracting integrated with mass analysis.
Technical scheme: the present invention is achieved by following technical proposals: it is below 5% that silkworm chrysalis is dried to water content, with its pulverizing, choose granularity 10-80 purpose silkworm chrysalis grain and place extractor afterwards, the participation in the election extraction temperature is 15～50 ℃, the extraction time is 0.5～4h, CO
2Flow is 15～35kg/h, and extracting pressure is 10～30MPa, can obtain rough silkworm chrysalis oil through needle-valve, separator, collector, obtains purer silkworm chrysalis oil after the centrifugal removal of impurities.
Described exsiccant silkworm chrysalis water content is preferably 3%～5%, and described silkworm chrysalis grain is preferably 20～40 orders, and choosing temperature is 35 ℃, and extracting pressure is 20MPa; CO
2Flow is 35kg/h; The extraction time is 3.5h.
Beneficial effect: supercritical CO
2Abstraction technique is a kind of novel innoxious solvent abstraction technique.This technology is with supercritical CO
2Fluid utilizes under differing temps and pressure the difference in solubility of different substances is separated it, be specially adapted to fat-soluble, boiling point is high, the extraction of heat sensitivity material.Supercritical technology is not only applicable to the exquisiteness of different components in the liquid mixture to be separated, and is widely used in industries such as medicine, chemical industry.Compared with prior art, the present invention has that production technique is simple, oil yield is high, the cycle is short, production cost is low, organic solvent-free is residual and the incomparable advantage of traditional technology such as operational condition gentleness.Having overcome in the sepn process of conventional art extraction method needs distillation heating, the easy oxidative rancidity of grease, has dissolvent residual, and shortcoming such as low, the exquisite technology of milling process productive rate is loaded down with trivial details, product color is undesirable.Extract this health substance of silkworm chrysalis oil and be used for the treatment of and preventing disease from silkworm chrysalis, can turn waste into wealth, the comprehensive utilization natural resource make it to become nexhaustible resource treasure-house.It is the inevitable of history that extraction process is moved towards the modern times by tradition, and along with development of productivity, supercritical extraction technique will promote the desirable kingdom that modern extraction process arrives at people, makes them can be human better service.
