Description

Technical Field

[0001] This utility model relates to the field of distillation and extraction technology, specifically to a distillation and extraction device for preparing Artemisia argyi essential oil. Background Technology

[0002] Artemisia essential oil is a volatile aromatic substance extracted from the leaves and stems of Artemisia argyi. Its main components include volatile oils and flavonoids, with the volatile oils possessing various biological activities such as antibacterial, anti-inflammatory, and antiviral properties. Artemisia essential oil has a pungent and bitter taste, and is warm in nature. It primarily enters the liver, spleen, and kidney meridians, possessing multiple effects such as dispelling cold, removing dampness, relieving pain, antibacterial properties, anti-inflammatory effects, warming the meridians, promoting blood circulation, replenishing qi, and enhancing immunity. It can help relieve body pain, soothe muscle tension, improve sleep quality, and can also be used in skin care to promote transdermal drug absorption. The extraction of Artemisia essential oil requires the use of a distillation extraction apparatus.

[0003] For example, authorization announcement number CN218174897U discloses an apparatus for distilling and extracting essential oils from aquatic plants. It includes a distillation kettle, a heater, a condenser, and a water-oil separator. The lower right end of the distillation kettle is connected to the top of the heater, the top of the distillation kettle is connected to the top of the condenser, and the lower end of the condenser is connected to the water-oil separator. The distillation kettle includes a main body, a lid, and a container. The lid is located on the top of the main body, and the container is movably mounted inside the main body. The beneficial effects of this invention, achieved by using layered placement of raw materials, increase the contact area between the raw materials and water vapor, improving extraction efficiency; and the condensed water is discharged into the heater for reuse, making it environmentally friendly and economical.

[0004] In the above-mentioned technology, the raw material is suspended in the container to allow it to fully contact the steam. However, the raw material still accumulates inside the container, resulting in limited contact between the middle part of the accumulated raw material and the steam, which in turn affects the distillation effect. Therefore, there is an urgent need in the market to develop a distillation and extraction device for the preparation of Artemisia argyi essential oil to help people solve the existing problems.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a distillation and extraction device for preparing Artemisia argyi essential oil, comprising a distillation device 1, an isolation plate 101 fixedly connected to the lower end of the distillation device 1, a material container 3 disposed inside the distillation device 1 and above the isolation plate 101, a stirring shaft 302 rotatably connected to the middle of the material container 3, multiple stirring rods 303 fixedly connected to both sides of the stirring shaft 302, a drive motor 102 fixedly disposed inside the distillation device 1 and at the middle of the lower end of the isolation plate 101, a transmission shaft 2 fixedly connected to the output shaft of the drive motor 102, the upper end of the transmission shaft 2 extending through the middle of the isolation plate 101 to the upper end of the isolation plate 101, and limit rods 201 fixedly connected to both ends of the transmission shaft 302. A rotating connector 304 is fixedly connected to the lower end face of the material container 3. A circular slot 305 is provided in the middle of the lower end face of the rotating connector 304. Rectangular slots 306 are connected between the two sides of the circular slot 305 and the outer end face of the rotating connector 304. The upper end of the drive shaft 2 is inserted into the circular slot 305. Two limit rods 201 slide into the two rectangular slots 306 respectively. The drive motor 102 drives the drive shaft 2 to rotate, so that the drive shaft 2 drives the stirring shaft 302 to rotate through the rotating connector 304. In turn, the stirring shaft 302 drives multiple stirring rods 303 to stir the Artemisia argyi raw material in the material container 3, prevent the Artemisia argyi raw material from accumulating, ensure that the steam and Artemisia argyi raw material are in full contact, and improve the distillation efficiency.

[0024] Please see Figure 1-3 The container 3 is made of a mesh structure, allowing steam to enter the container 3 through the mesh structure. The upper end of the container 3 extends out of the upper surface of the distillation device 1 and is fixedly connected to an annular support plate 301. The annular support plate 301 supports the container 3, and the container 3 can be lifted out from the upper end of the distillation device 1 for easy loading and unloading. The upper end of the annular support plate 301 is provided with a top cover 103. A steam generator 4 is connected to one side of the distillation device 1. The distillation device 1 and the steam generator 4 are connected by a steam delivery pipe 401. Steam generated by the steam generator 4 is delivered to the interior of the distillation device 1 through the steam delivery pipe 401. A condenser 5 is provided on the other side of the distillation device 1. An oil-water separator 6 is connected to the lower end of the condenser 5. The upper end of the top cover 103 is connected to the upper end of the condenser 5 through an output pipe 104. The distilled artemisia oil enters the condenser 5 through the output pipe 104 for condensation. After condensation, it enters the oil-water separator 6 for purification.

[0025] Working Principle: In operation, the mugwort raw material is first placed in the holding tank 3. The mesh structure of the holding tank 3 allows steam to freely penetrate and fully contact the mugwort raw material. Then, the drive motor 102 is started, and its output shaft drives the transmission shaft 2 to rotate. The transmission shaft 2 is connected to the stirring shaft 302 via a rotating connector 304, which in turn drives the stirring shaft 302 and its two side stirring rods 303 to rotate inside the holding tank 3, effectively agitating the mugwort raw material, preventing its accumulation, and ensuring that the steam can fully contact all parts of the mugwort raw material, improving distillation efficiency. Simultaneously, the steam generator 4 starts working, and the generated high-temperature steam is sent into the distillation apparatus 1 through the steam delivery pipe 401 to exchange heat with the mugwort raw material, extracting mugwort essential oil. The distilled mugwort essential oil and its accompanying water vapor then enter the condenser 5 through the output pipe 104 for condensation. The condensed liquid then enters the oil-water separator 6 for purification.
