Description

Technical Field

[0001] This utility model belongs to the field of distillation and extraction technology, specifically relating to a distillation and extraction device for extracting essential oil from perfume lemons. Background Technology

[0002] In numerous industries such as fragrance, food, and daily chemicals, perfume lemon essential oil is highly favored for its unique aroma and wide range of uses, becoming an important natural raw material in the market. Distillation extraction is one of the most widely used methods for extracting perfume lemon essential oil due to its advantages such as relatively simple operation, high extraction efficiency, and good preservation of essential oil components and aroma.

[0003] Existing essential oil extraction methods generally employ two types: double-distillation and water-fed distillation. Double-distillation involves placing the material to be distilled on a sieve plate inside a distillation vessel, with a certain amount of water placed below the sieve plate. Heating the water causes it to boil, generating steam. This steam passes through the holes in the sieve plate and heats the material, thus achieving the distillation process. Water-fed distillation, on the other hand, involves directly adding water to the material and then heating it. During heating, the water and material boil together, and the generated steam carries the volatile components from the material out through distillation. Generally, double-distillation is suitable for extracting essential oils that are sensitive to temperature or prone to hydrolysis, such as some floral essential oils like rose and neroli, and some fruit peel essential oils like lemon and orange. These essential oils typically have high volatility, and double-distillation can better preserve their aroma and chemical components.

[0004] When traditional essential oil distillation equipment distills perfume lemon peels, the peels are usually piled up, making it difficult for steam to fully contact them. This results in poor distillation efficiency and low extraction utilization of essential oils from the lemon peels. Summary of the Invention

[0005] In order to overcome the problem that in the traditional essential oil distillation extraction device in the background art, when distilling perfume lemon peel, the lemon peel is usually piled up, making it difficult for steam to fully contact the peel, resulting in poor distillation effect and low extraction utilization rate of essential oil in the lemon peel, this utility model provides a distillation extraction device for extracting essential oil from perfume lemon, which can turn the perfume lemon peel in the distillation tank so that the steam can fully contact the peel.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A distillation extraction device for extracting essential oil from perfume lemon mainly includes a placement rack, a distillation tank, a stirring assembly, and a rotary motor. The placement rack is a hollow annular structure. The distillation tank is installed on the placement rack. The top of the distillation tank is provided with a removable sealing cover. The bottom of the distillation tank is provided with a heating chamber. Above the heating chamber is a distillation chamber. The bottom of the distillation chamber is a mesh support plate. A driven gear disk is provided on the outer wall of the bottom of the distillation chamber. The rotary motor is installed on one side of the distillation tank. A driving gear disk is provided on the output shaft of the rotary motor. The two gear disks mesh and drive each other. The stirring assembly is installed inside the distillation chamber.

[0007] Furthermore, the distillation chamber and the distillation vessel are rotatably connected by bearings.

[0008] Furthermore, the stirring assembly includes a drive motor, a rotating shaft, and stirring blades. The drive motor is mounted on the top of the distillation tank, the rotating shaft extends through the top of the distillation tank to the distillation chamber, a high-temperature resistant sealing ring is provided at the connection between the rotating shaft and the top of the distillation tank, and the stirring blades are mounted on the rotating shaft.

[0009] Furthermore, the stirring blade is an asymmetrical arc-shaped column, with the stirring blade on one side of the rotating shaft bulging downwards and the other side bulging upwards.

[0010] Furthermore, the sealing cap is provided with a steam port, which is connected to the condenser via a connecting pipe.

[0011] The beneficial effects of this utility model are:

[0012] In this invention, the rotary motor meshes with the driven gear at the bottom of the distillation chamber via a drive gear disc, enabling stable power transmission and driving the distillation chamber to rotate. This design, combined with the stirring assembly, prevents material agglomeration and accelerates the release of volatile components. The stirring assembly also prevents material from accumulating on the grid support plate, allowing the material to fully contact the steam and accelerating the uniformity of heating, thereby improving the efficiency of essential oil release. This device, through the combined design of dynamic stirring and rotary distillation, can greatly improve the efficiency of traditional steam distillation. Attached Figure Description

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0019] This utility model discloses a distillation extraction device for extracting essential oil from lemon. The device mainly includes a placement rack 1, a distillation tank 2, a stirring assembly 3, and a rotary motor 4. The placement rack 1 is a hollow annular structure. The distillation tank 2 is mounted on the placement rack 1. The top of the distillation tank 2 is equipped with a removable sealing cover 203. The bottom of the distillation tank 2 is equipped with a heating chamber 201, and above the heating chamber 201 is a distillation chamber 202. The bottom of the distillation chamber 202 is a mesh support plate, and a driven gear disk 6 is provided on the outer wall of the bottom of the distillation chamber 202. The rotary motor 4... Installed on one side of the distillation tank 2, the rotary motor 4 has a drive gear disk 5 on its output shaft, and the two gear disks mesh for transmission. The stirring assembly 3 is installed inside the distillation chamber 202. In this invention, the rotary motor 4 meshes with the driven gear disk 6 at the bottom of the distillation chamber 202 through the drive gear disk 5, which can achieve stable power transmission and drive the distillation chamber 202 to rotate. This design, combined with the stirring assembly 3, can prevent material agglomeration and accelerate the release of volatile components. The stirring assembly 3 can prevent material from accumulating on the grid support plate, so that the material can fully contact the steam, accelerate the uniformity of material heating, and thus improve the efficiency of essential oil release.

[0020] The distillation chamber 202 and the distillation tank 2 are rotatably connected by bearings; this structure can reduce rotational friction resistance and improve transmission stability. The bearing connection allows the distillation chamber 202 to rotate stably in the distillation tank 2 while maintaining a seal, which helps to heat and stir evenly and improve the efficiency of essential oil extraction.

[0021] The stirring assembly 3 includes a drive motor 301, a rotating shaft 302, and stirring blades 303. The drive motor 301 is mounted on the top of the distillation tank 2, and the rotating shaft 302 extends through the top of the distillation tank 2 to the distillation chamber 202. A high-temperature resistant sealing ring is provided at the connection between the rotating shaft 302 and the top of the distillation tank 2. The stirring blades 303 are mounted on the rotating shaft 302. The stirring assembly 3, installed inside the distillation chamber 202, enhances the flow of the lemon peel, reduces dead corners, and ensures that the lemon peel is in full contact with the steam.

[0022] The stirring blade 303 is an asymmetrical arc-shaped column. The stirring blade 303 on one side of the rotating shaft 302 bulges downward and on the other side bulges upward. The asymmetrical arc difference of the arc-shaped column will generate radial shear forces of different intensities, further breaking up the layering of the lemon peel, reducing the stirring dead angle, and enhancing the lateral mixing effect.

[0023] The sealing cap 203 is provided with a steam port 7, which is connected to the condenser through a connecting pipe. Steam enters the connecting pipe from the distillation tank 2 through the steam port 7 of the sealing cap 203, and is then rapidly liquefied through the condenser, finally flowing into the condensate collection bottle for recycling.

[0024] Work process:

[0025] In practical use, the sealing cap 203 is opened, and the shredded lemon peels are spread evenly on the grid support plate at the bottom of the distillation chamber 202. This ensures that steam can penetrate the material layer evenly. The grid structure can support the material and prevent debris from clogging the heating chamber 201 below. Then, the removable sealing cap 203 is installed and connected to the condenser through the connecting pipe. Ensure that the cooling water inlet and outlet directions are correct to form a continuous cooling cycle. Steam is introduced into the bottom heating chamber 201, so that the temperature of the distillation chamber 202 gradually rises to the boiling point of limonene. During the heating process, the grid support plate evenly transfers heat to the material, reducing the risk of local overheating. The rotary motor 4 meshes with the driven gear disk 6 through the active gear disk 5, driving the distillation chamber 202 to rotate as a whole, moving synchronously in the opposite direction to the internal stirring component 3. The stirring component 3 continuously turns the material during rotation, improving the evaporation efficiency of essential oils and preventing uneven heat transfer caused by peel accumulation. This device, through the combination design of dynamic stirring and rotary distillation, can greatly improve the efficiency of traditional steam distillation.

[0026] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
