Description

Technical Field

[0001] This utility model belongs to the field of artemisia essential oil processing technology, specifically relating to a separation and determination device for extracting artemisia essential oil. Background Technology

[0002] Artemisia argyi, a perennial herb belonging to the genus Artemisia in the family Asteraceae, is also known as mugwort, wormwood, and medicinal herb. Its plant has a strong aroma, thick, papery leaves covered with short, grayish-white hairs, and white glandular dots and small pits; the flower heads are elliptical, with tubular or goblet-shaped corollas. Artemisia argyi is an important plant resource in traditional Chinese medicine and folk culture. Artemisia argyi essential oil is a volatile aromatic substance extracted from the leaves and stems of Artemisia argyi, possessing a unique aroma and various bioactive components. Rich in flavonoids, alcohols, and trace elements, Artemisia argyi essential oil has antibacterial, antiviral, anti-inflammatory, analgesic, and antioxidant effects, and is widely used in medicine, health care, and beauty. During the processing of Artemisia argyi essential oil, the essential oil and water are usually mixed together during distillation. Since the essential oil is less dense than water, it floats on the surface. Using a separation device, the essential oil and water can be efficiently separated to obtain pure essential oil.

[0003] Currently, most of the separation and testing devices for extracting mugwort essential oil on the market do not have a layered structure inside the distillation tower when heating mugwort. The mugwort raw material is directly put into the distillation tower during heating. Although the volume of mugwort that can be put in is large, the steam generation space is small during the heating process, the gaps between the mugwort are small, and the contact between the steam and the mugwort is insufficient, resulting in a low essential oil extraction rate. Utility Model Content

[0004] The purpose of this invention is to provide a separation and determination device for extracting Artemisia argyi essential oil. By setting multiple perforated partition plates in the distillation tower, Artemisia argyi is evenly spread on each partition plate, thereby increasing the contact area between Artemisia argyi and steam and improving the essential oil extraction rate.

[0007] The base plate is sequentially fixed with a distillation unit, a condensation unit, and a separation unit, which are fixed by a bracket.

[0008] The distillation unit includes a distillation column with a steam outlet at the top. Multiple partition plates are arranged axially within the distillation column, and each partition plate has through holes for steam to pass through.

[0009] The steam outlet of the distillation column is connected to the steam inlet at the top of the condensation unit via a connecting pipe, and the condensation unit forms a water circulation path with the distillation unit via a water supply pipe at the bottom;

[0010] The oil-water outlet of the condensation unit is connected to the inlet of the separation unit via a downwardly inclined conveying pipe. The separation unit is equipped with a stratified liquid outlet.

[0011] In a preferred embodiment, the distillation unit further includes a door disposed on one side of the distillation column, the door being provided with a handle, and the door being sealed by a snap fastener disposed on the side wall of the distillation column.

[0012] In a preferred embodiment, the condensation unit includes a condensation tower with spiral condenser tubes, the inlet and outlet of which are respectively connected to a connecting pipe and a conveying pipe.

[0013] In a preferred embodiment, the side wall of the condensing tower is provided with an inlet and an outlet for condensing water, respectively, and the direction is different from that of the delivery pipe.

[0014] In a preferred embodiment, the separation unit includes a separating tank, the inlet of which is connected to a delivery pipe, a separating hopper is fixedly connected to the bottom of the separating tank, and the separating hopper is equipped with a dispensing valve with valve control.

[0015] In a preferred embodiment, the base plate has a notch at the outlet of the liquid outlet valve to facilitate the placement of the collection bottle.

[0029] like Figures 1 to 2 As shown, a separation and determination device for extracting Artemisia argyi essential oil includes a base plate 1.

[0030] A distillation unit 3, a condensation unit 5, and a separation unit 8, which are fixed in sequence by a bracket 2, are mounted on the base plate 1.

[0031] The distillation unit 3 includes a distillation column 31 with a steam outlet at the top. Multiple partition plates 35 are arranged axially inside the distillation column 31, and each partition plate 35 has a through hole for steam to pass through.

[0032] The steam outlet of the distillation column 31 is connected to the steam inlet at the top of the condensation unit 5 via the connecting pipe 4. The condensation unit 5 forms a water circulation path with the distillation unit 3 via the water supply pipe 6 at the bottom.

[0033] The oil-water outlet of the condensation unit 5 is connected to the inlet of the separation unit 8 via a downwardly inclined conveying pipe 7. The separation unit 8 is equipped with a stratified liquid outlet.

[0034] In the above embodiment, when the device is needed, the handle 33 is pulled to open the door 32, and then the mugwort raw materials are laid on the partition plate 35 so that each layer of mugwort can fully contact the steam. Then the door 32 is closed to start heating the mugwort. The generated steam will enter the condensation unit 5 through the connecting pipe 4. The water injected into the inner cavity of the condensation tower 51 can enter the distillation tower 31 through the water supply pipe 6 to provide a water source for heating the mugwort to generate water vapor. Excess water can be discharged through the outlet 54. After the steam becomes a water-oil mixture in the condensation unit 5, it enters the separation unit 8 through the conveying pipe 7. The separator 82 is made of transparent material. After extraction, the mugwort hydrosol and mugwort essential oil will separate due to their different densities. Then the valve of the liquid outlet valve 83 is turned to extract the mugwort hydrosol first. The dividing line is observed through the separator 82. After the mugwort hydrosol is extracted, the valve of the liquid outlet valve 83 is turned to extract the mugwort essential oil.

[0035] like Figure 3 As shown, the distillation unit 3 also includes a door 32 that can be opened and closed and is provided on one side of the distillation column 31. The door 32 is provided with a handle 33 and is sealed by a buckle 34 provided on the side wall of the distillation column 31.

[0036] In the above embodiment, a sealing ring is provided on the inner side of the door 32 to prevent water vapor leakage during the heating process, and the bottom of the distillation column 31 is provided with a temperature-controllable electric heating device. This is prior art, so it will not be described in detail here.

[0037] like Figure 4 As shown, the condensation unit 5 includes a condensation tower 51 with a spiral condensation tube 52. The liquid inlet and liquid outlet of the condensation tube 52 are connected to the connecting pipe 4 and the conveying pipe 7, respectively. The side wall of the condensation tower 51 is provided with an inlet 53 and an outlet 54 for the inlet and outlet of condensing water, respectively, and the direction is different from that of the conveying pipe 7.

[0038] In the above embodiment, the water used for condensation enters the inner cavity of the condenser 51 from the inlet 53 above the condenser 51, cools and condenses the steam in the condenser tube 52 into an oil-water mixture, and the used water can be transported into the distillation tower 31 through the water supply pipe 6 for recycling, and the excess water can be discharged to a suitable location through the outlet 54 below the condenser 51.

[0039] like Figure 5 As shown, the separation unit 8 includes a liquid separator 81, the liquid inlet of which is connected to the delivery pipe 7, and a liquid separator 82 is fixedly connected to the bottom of the liquid separator 81. The liquid separator 82 is equipped with a liquid outlet valve 83 with valve control.

[0040] In the above embodiment, the separator 82 is made of transparent material, which makes it easy to observe the water level of the oil-water mixture inside.

[0041] like Figure 1 As shown, a notch is provided on the base plate 1 at the outlet of the liquid outlet valve 83 to facilitate the placement of the collection bottle.

[0042] In the above embodiment, a notch is provided on the base plate 1 corresponding to the liquid outlet valve 83, so that the collection bottle can be placed below the liquid outlet valve 83 without being limited by the height between the base plate 1 and the liquid outlet valve 83.

[0043] The working principle of this utility model is as follows: When the device is needed, pull the handle 33 to open the door 32, then place the mugwort raw materials on the partition plate 35 so that each layer of mugwort can fully contact the steam. Then close the door 32 and use the buckle 34 set on the side wall of the distillation tower 31 to close the door 32 and the distillation tower 31 tightly. Start heating the mugwort. The generated steam will enter the condensation unit 5 through the connecting pipe 4. Water is injected into the inner cavity of the condensation tower 51 through the water inlet 53 to condense the steam. After the steam enters the condenser tube 52 through the connecting pipe 4, it can cool and condense the water vapor in the condenser tube 52 into liquid. The condenser tube 52 is spiral-shaped. To ensure rapid cooling of the steam into an oil-water mixture, water injected into the inner cavity of the condenser 51 can enter the distillation tower 31 through the water supply pipe 6, providing a water source for heating the mugwort to generate steam. Excess water can be discharged through the outlet 54. After the steam becomes a water-oil mixture in the condenser unit 5, it enters the separation unit 8 through the conveying pipe 7. The separator hopper 82 is made of transparent material. After extraction, the mugwort hydrosol and mugwort essential oil will separate due to their different densities. The mugwort hydrosol is extracted by turning the outlet valve 83 first. The dividing line is observed through the separator hopper 82. After the mugwort hydrosol is extracted, the mugwort essential oil can be extracted by turning the outlet valve 83.

[0044] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
