Description

Technical Field

[0001] This invention relates to the field of Artemisia argyi processing equipment, specifically to an Artemisia argyi extract distillation device. Background Technology

[0002] Artemisia argyi extract is generally extracted by steam distillation. The steam distillation device is mainly divided into a steam component, a distillation component, and a condensation component. The steam component generates steam to distill the artemisia argyi in the distillation component. The steam generated during the distillation process enters the condensation component to cool and collect the artemisia argyi extract.

Beneficial effects

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 2. The nozzle is set on the plane of the acute angle side of the rod, so that when the rod rotates, the nozzle is in a cavity that does not come into contact with the mugwort, thus avoiding the blockage of the nozzle by powder and impurities inside the mugwort;

[0021] 3. While the steam box is raised and lowered by the lifting drive unit, the raising and lowering of the steam hood assembly can also be adjusted to achieve the sealing and separation of the steam hood assembly and the shell structure.

[0022] 4. The spiral steam duct is spiral in shape, which can increase the contact area with the cooling water and the cooling stroke. After cooling, the water can be easily discharged from the first drain pipe.

[0023] 5. In practical applications, the screening mesh is used to separate mugwort and water, that is, to separate mugwort and water after washing mugwort, and to separate mugwort and the water produced by distillation after mugwort is distilled; it also acts as a bridging slide when mugwort is discharged.

[0024] 6. Through the mutual coordination and cooperation among the shell structure, stirring components, steam diversion hood components, screening net, spiral steam duct, steam box and lifting drive unit, it is possible to achieve functions such as greatly improving the distillation and extraction efficiency of Artemisia argyi liquid, facilitating the addition and removal of Artemisia argyi, and recycling of water liquid to save resources, forming an inseparable whole.

[0038] A steam discharge structure is provided between the stirring rod structure 308 and the steam box 7. The steam discharge structure is used to eject the steam inside the steam box 7 from the stirring rod structure 308.

In practical applications, the screening net 5 is used to separate mugwort and water, that is, to separate mugwort and water after washing mugwort, and to separate mugwort and the water produced by distillation after mugwort is distilled; it also acts as a bridging slide when the mugwort is discharged. At this time, the outer shell 201 is lowered to the lowest position height under the drive of the first electric telescopic rod 203, and the cross-sectional shape of the screening net 5 is inclined straight, which facilitates the movement of the mugwort on the upper surface of the steam box 7 into the collection box 204 for easy processing.

After cooling, the water can be discharged through the first drain pipe 12. Specifically, two spiral steam ducts 6 are provided, corresponding to the telescopic air guide pipe 404. The two spiral steam ducts 6 can also be interlocked vertically within the cooling water storage chamber 9.

These elastic pressure rods 403b are evenly distributed at equal angles around the central axis of the rotating rod 306. Through the above-mentioned specific structural design, the elastic pressure rod 403b can achieve elastic sealing and pressing between the steam hood assembly 4 and the upper opening edge of the inner shell 205, thereby achieving an elastic and tight connection between the steam hood assembly 4 and the inner shell 205.

The lower end of the gas-liquid channel 307 is open and communicates with the interior of the steam box 7. The gas-liquid channel 307 and the steam channel 308b are connected to each other. Through the above-mentioned specific structural design, during the stirring and turning of the mugwort by the stirring rod structure 308, the steam discharged from the nozzle 308c can achieve all-round distillation contact with the mugwort without dead angles. Furthermore, the nozzle 308c is set on the plane of the acute angle side of the rod 308a, so that the nozzle 308c is in a cavity that does not contact the mugwort when the rod 308a rotates, avoiding the blockage of the nozzle 308c by powder impurities in the mugwort.

[0048] Working principle:

[0049] For usage, please refer to the instruction manual attached. Figure 3 As shown, the lifting drive unit 8 drives the steam box 7 to move upward, causing the steam diversion hood assembly 4 to separate from the upper side of the shell structure 2. A gap is formed between the shell structure 2 and the steam diversion hood assembly 4 for placing mugwort on the upper surface of the steam box 7. The staff places the mugwort on the upper surface of the steam box 7 through this gap and washes the mugwort through the external water pipe. During the washing process, the stirring assembly 3 can stir and turn the mugwort on the upper surface of the steam box 7, making the cleaning more thorough. After washing, the lifting drive unit 8 drives the steam box 7 to continue to move upward, so that the upper surface of the steam box 7 protrudes from the upper opening of the lifting chamber. The water in the mugwort flows through the screening net 5 to the cooling water storage chamber 9, which is used to cool the steam introduced into the spiral steam pipe 6. The lifting drive unit 8 drives the steam box 7 to move downward, thereby driving the stirring assembly 3 and the steam diversion hood assembly 4 to move downward in sequence, until the lower side of the steam diversion hood assembly 4 and the upper side of the shell structure 2 are sealed together, thus sealing the steam chamber.

[0050] The electric heater 18 inside the steam box 7 operates to heat and evaporate the water in the steam box 7. The steam generated by evaporation is discharged sequentially through the gas-liquid channel 307, the steam channel 308b and the nozzle 308c. Thus, while the mugwort is stirred and turned by the stirring rod structure 308, the mugwort can also be distilled. The steam after the mugwort is distilled continues to rise and enters the spiral steam conduit 6 through the steam guide hood assembly 4. After cooling, it is discharged through the first drain pipe 12.

[0051] After distillation, the lifting drive unit 8 drives the steam box 7 to move upward. After the upper surface of the steam box 7 protrudes from the upper opening of the lifting chamber, the operator can quickly scrape the mugwort onto the sieve net 5 with the scraping action of the stirring rod structure 308 of the stirring assembly 3. After sieving, the liquid falls into the cooling water storage chamber 9. After sieving, the first electric telescopic rod 203 drives the upper outer shell 202 to move downward, so that the upper edge of the upper outer shell 202 is lower than the upper edge of the inner shell 205. The mugwort falls from the sieve net 5 into the collection box 204 for collection, and then the operator can process it.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
