Description

Technical Field

[0001] The invention relates to the technical field of emu oil extraction, and in particular to an extraction device and a method for anti-inflammatory and absorption-promoting emu oil. Background Art

[0002] Emu oil is a type of oil extracted from the fat sac on the back of the emu. It has natural anti-inflammatory properties and deep penetration ability. It can directly reduce inflammation in inflamed joints and may have a certain relieving effect on arthritis.

[0003] Traditional emu oil extraction processes include supercritical carbon dioxide extraction, molecular distillation, etc. Some of these methods have complex process flows and require expensive instruments, while other methods, although relatively simple process flows, require deodorization at high temperatures, which will lead to changes in active ingredients such as unsaturated fatty acids in emu oil, thereby reducing the use value of emu oil.

[0004] In order to solve the above problems, Chinese invention patent CN116463169A discloses an emu oil extraction and purification device, which uses a Soxhlet extractor to extract emu oil, and a receiving chamber containing an adsorbent is provided in the siphon of the Soxhlet extractor, and the extracted emu oil is deodorized and / or decolorized by the adsorbent in the receiving chamber.

[0050] Reference Figure 5 The condenser 500 includes an outer tube body 510, an inner tube body 520 and a central tube 530 which are arranged concentrically. A cooling liquid circulation cavity with closed ends is formed between the outer tube body 510 and the inner tube body 520.

[0051] In this embodiment, in order to facilitate installation and removal of the basket 540, the upper end of the basket 540 is connected to the lower end of the inner tube body 520 of the condenser 500 through a threaded interface.

[0052] The lower end of the extrusion rod 600 passes through the central tube 530 and is provided with a filter press plate 610, the upper part of the frame 100 is provided with a movable frame 110, the upper end of the extrusion rod 600 passes through the movable frame 110 and is provided with an upper baffle 620 limited to the upper side of the movable frame 110, the extrusion rod 600 is provided with a lower baffle 630 located between the condenser 500 and the movable frame 110, and the outer sleeve of the extrusion rod 600 is provided with a spring 640 supported between the lower baffle 630 and the movable frame 110.

[0053] The lifting mechanism is installed on the moving frame 110 and is used to drive the condenser 500 to move up and down.

[0054] Reference Figure 1 The lifting mechanism includes telescopic cylinders 700 symmetrically arranged on both sides of the extraction pipe 400. The telescopic cylinders 700 are specifically electric telescopic cylinders. A support frame 550 is provided outside the condenser 500. The upper ends of the telescopic cylinders 700 are respectively fixed on the moving frame 110, and the lower ends of the telescopic cylinders 700 are respectively fixed on the support frame 550. In this way, the condenser 500 can be driven to rise and fall by controlling the synchronous extension and contraction of the two telescopic cylinders 700.

[0055] In this embodiment, the mobile frame 110 uses a translational method to move the condenser 500. Specifically, refer to Figure 1 , rail grooves 111 are symmetrically arranged on both sides of the frame 100, and both sides of the mobile frame 110 are respectively installed in the corresponding rail grooves 111 through rollers 112.

[0057] The embodiment of the present invention also provides a method for extracting anti-inflammatory and absorption-promoting emu oil, comprising the following steps:

[0058] Step S10, loading the emu oil extraction raw material into the net basket 540, and installing the net basket 540 at the lower end of the inner tube body 520 of the condenser 500;

[0059] Step S20, controlling the moving frame 110 to move the condenser 500 to the top of the extraction tube 400, and controlling the lifting mechanism to drive the condenser 500 to descend until the lower end of the condenser 500 is inserted into the upper end of the extraction tube 400;

[0060] Step S30, loading the extraction solvent into the extraction container 200 and installing the extraction container 200 at the lower end of the filter tube 300;

[0061] Step S40, heating and evaporating the extraction solvent in the extraction container 200, the extraction solvent vapor enters the air guide pipe 430 from the lower part of the filter tube 300, and enters the upper part of the extraction tube 400 through the air guide pipe 430, and then enters the condensation chamber of the condenser 500 through the vent hole 521 on the tube body 520 in the condenser 500 for condensation and liquefaction, the liquefied extraction solvent flows into the extraction tube 400 and extracts the extraction raw materials in the basket 540, when the solution in the extraction tube 400 is higher than the siphon tube 420, the solution in the extraction tube 400 is sucked into the upper part of the filter tube 300 through the siphon tube 420, and flows into the extraction container 200 after adsorption and filtration by the adsorption filter element 310 in the filter tube 300;

[0062] Step S50, repeating step 40 to extract the emu oil multiple times;

[0063] Step S60, after the extraction is completed, the switch valve 411 is controlled to open, the lifting mechanism drives the condenser 500 to rise, and the filter pressing plate 610 at the lower end of the squeezing rod 600 squeezes the extraction raw material in the basket 540, so as to discharge the residual solution in the extraction raw material, and the discharged solution is discharged into the upper part of the filter tube 300 through the connecting tube 410, and flows into the extraction container 200 after adsorption filtration by the adsorption filter element 310 in the filter tube 300;

[0064] Step S70, after the basket 540 at the lower end of the condenser 500 is lifted out of the extraction pipe 400, the movable frame 110 is driven to move the basket 540 to the unloading area, and then the lifting mechanism is controlled to drive the condenser 500 to descend until the filter press plate 610 exits the basket 540;

[0065] Step S80, the basket 540 is removed from the lower end of the condenser 500, and the extraction raw material residue in the basket 540 is poured out.

[0066] When the present invention is used to take and place the raw materials for extraction, the net basket 540 can be lifted out of the extraction tube 400, and the net basket 540 can be removed from the condenser 500, so that the raw materials for extraction can be easily taken and placed. Moreover, during the normal extraction of emu oil, the extraction liquid in the extraction tube 400 can be sucked into the filter tube 300 through the siphon tube 420, and after being adsorbed and filtered by the adsorption filter element 310 in the filter tube 300, it flows into the extraction container 200. When the net basket 540 is lifted out of the extraction tube 400 after the extraction is completed, the filter plate 610 at the lower end of the squeezing rod 600 will be pressed by the spring 640. The filter residue in the basket 540 is squeezed, and the switch valve 411 on the connecting pipe 410 is opened at this time. The squeezed extraction solution can flow into the filter tube 300 through the connecting pipe 410, and after adsorption filtration by the adsorption filter element 310 in the filter tube 300, it flows into the extraction container 200. This not only meets the adsorption and filtration of the emu oil extraction solution in the whole process, but also can reduce the solution residue in the raw material residue during the slag discharge. Under the premise of ensuring the same extraction degree of the extracted raw materials, the number of extractions can be reduced by 2-3 times, thereby reducing the extraction time of the emu oil and reducing energy consumption.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
