Description
Technical field
The present invention relates to natural plant pefume to purify field, particularly a kind of agalloch eaglewood Edgeworthia chrysantha extraction system.
Background technology
Agalloch eaglewood trees are Thymelaeceae (Thymelaeaceae) agalloch eaglewood category (Aquilaria) suspension culture of Aquilaria sinensis (Aquilaria
Sinensis (Lour.) Gilg) and congener agalloch eaglewood (Aquilria agallocha Roxb.) trees.When its trunk meets with
Bitten by insect and sting, will secrete grease automatically in trunk after natural calamity or artificial injury, this is also oneself of nature trees
More property, secreted grease among nature by certain specific fungal infection after, it is this with the gradual passage of time
Grease can give out a kind of unusual fragrance, and this brownish black grease in trunk is exactly agalloch eaglewood Edgeworthia chrysantha.Because of its exclusive fragrance,
It is commonly used for preparing spices and perfume.
The conventionally employed steam distillation extraction of agalloch eaglewood Edgeworthia chrysantha, elapsed time is long, active ingredient is easily destroyed；Also there is use
Organic solvent such as ethanol, gasoline or petroleum ether extraction, there are the problem of inflammable and explosive dangerous and organic solvent residual.Therefore, product
The unfavorable factors such as matter is low, high energy consumption and pollution are big, seriously limit the development and application of agalloch eaglewood Edgeworthia chrysantha.
People, which begin attempt to extract from agalloch eaglewood Edgeworthia chrysantha woody part using supercritical CO 2 extraction technology, to be contained
There is the mixing medicinal extract of agalloch eaglewood Edgeworthia chrysantha.Existing extraction kettle is hollow, and it is broken that agalloch eaglewood Edgeworthia chrysantha wood is directly inserted in inside, and carbon dioxide is from extraction
Bottom portion enters, and flows through agalloch eaglewood Edgeworthia chrysantha wood and broken is extracted.Due to can not fairly evenly divide when agalloch eaglewood Edgeworthia chrysantha wood is broken to be inserted
Cloth, loosely, some positions are closer for some positions so that the extraction path of carbon dioxide is easy for from loose position warp
Cross, close position cannot effectively extract, and cause yield not high, extraction efficiency is also low.
The content of the invention
In order to overcome the shortcomings of the prior art, the present invention provides a kind of efficiently agalloch eaglewood extraction system, its extraction yield,
Efficiency significantly improves.
To achieve the above object, the purpose of the present invention is be achieved in that：A kind of efficiently agalloch eaglewood extraction system, including overcritical
Carbon dioxide abstraction kettle, it is characterised in that：The supercritical carbon dioxide extracting kettle includes：Housing；Be placed in housing by shell
Body inner space is divided into the spacer mechanism of several extraction sections of longitudinal arrangement；It is communicated in the air inlet pipe of housing bottom, air inlet
Pipe include respectively with the one-to-one branched pipe in each extraction section.
Several described extraction sections and housing axis parallel.
The cross section of the extraction section is polygon, circle, ellipse or irregular shape.
The cross section of the extraction section is quadrangle.
Carbon dioxide abstraction condition is：Extracting pressure is 20~40MPa, and extraction temperature is 35~70 DEG C, extraction time 1
~4h.
Compared with prior art, extraction kettle inner space is separated into several extraction sections by the present invention using spacer mechanism,
So that agalloch eaglewood Edgeworthia chrysantha wood is more uniformly spread, there is independent carbon dioxide pipeline in each extraction section, so as to limit two
Carbonoxide must be flowed along each extraction section, and yield is extracted in identical extraction time and is significantly improved, extraction efficiency improves
20~30%.
Brief description of the drawings
Fig. 1 is the flowage structure schematic diagram of present device；
Fig. 2 is the internal structure schematic diagram of extraction kettle of the present invention；
Fig. 3 is the structure diagram of spacer mechanism of the present invention.
Embodiment
As shown in Figure 1, the present invention is a kind of efficiently agalloch eaglewood extraction system, including pass sequentially through the super of pipeline serial communication and face
Boundary's carbon dioxide abstraction kettle 12 and two-stage separation kettle 13,14.It is carbon dioxide air source 11 and high-pressure pump 16, heater 17, overcritical
Carbon dioxide abstraction kettle 12 connects.14 middle and upper part of afterbody separating still is connected with recycling carbon dioxide storage tank 15, recycles dioxy
Change carbon storage tank 15 to connect with high-pressure pump 16, heater 17, extraction kettle 12 successively, be formed into a loop, realize the circulation profit of carbon dioxide
With.What is discharged from two-stage separation kettle 13,14 bottoms is the mixing medicinal extract that includes agalloch eaglewood Edgeworthia chrysantha.
As shown in Figure 2 and Figure 3, the supercritical carbon dioxide extracting kettle 12 includes：Housing 121；It is placed in housing 121
Enclosure interior space is divided into the spacer mechanism 123 of several extraction sections 122 of longitudinal arrangement；It is communicated in 121 bottom of housing
Air inlet pipe 124, air inlet pipe 124 include divide respectively with the one-to-one branched pipe 125 in each extraction section 122, each branched pipe 125
Corresponding extraction section 122 is not inserted into be supplied.
Several described extraction sections 122 and 121 axis parallel of housing.
The cross section of the extraction section 122 can be polygon, circle, ellipse or irregular shape.
