The top of the distillation kettle 1 is connected to the primary purification tower 3 via a pipe, and the top of the primary purification tower 3 is connected to the cooler 4 via a pipe. After the plant extract is heated in the distillation kettle 1, the water vapor containing aromatic components undergoes preliminary purification in the primary purification tower 3, and then enters the cooler 4 for cooling. A semiconductor cooler 47 and a cooling plate 46 are installed on the cooler 4 to reduce the temperature of the heat exchange water. The magnetic stirring motor 43 drives the stirrer 44 to stir the hot water, improving its fluidity. This allows the heat from the water vapor in the serpentine coil 42 to be quickly removed and condensed, turning into a liquid consisting of a layer of essential oil and a layer of hydrosol, which is then discharged. The temperature controller 5 is used to adjust and control the temperature, ensuring that the hot water inside the cooler 4 is kept within the set temperature range. The temperature sensor 48 is used to monitor the water temperature inside the cooler 4 in real time. When the water temperature exceeds the set threshold, the temperature controller 5 is used to adjust the cooling temperature of the semiconductor cooler 47 and the speed of the magnetic stirring motor 43 to achieve a rapid heat exchange and cooling effect.

[0025] The distillation vessel 1 includes a vessel body 11 and a stirrer 12. The stirrer 12 is installed inside the vessel body 11. A water jacket 13 is provided on the outside of the vessel body 11. A thermometer 14, a pressure gauge 15, a level gauge 16 and a pressure relief valve 17 are respectively installed on the vessel body 11.

[0026] The primary purification tower 3 includes a tower body 31 and a bubble cap tray 32, wherein the bubble cap tray 32 is installed inside the tower body 31;

[0027] The cooler 4 includes a housing 41, a serpentine coil 42, a magnetic stirring motor 43, and a stirrer 44. The serpentine coil 42 is installed in the housing 41, the magnetic stirring motor 43 is installed at the bottom of the housing 41, and the stirrer 44 is placed at the inner bottom of the housing 41 and magnetically connected to the magnetic stirring motor 43. The side wall of the housing 41 is provided with an assembly port 45, and a cooling fin 46 is installed in the assembly port 45. A semiconductor cooler 47 is installed on the outside of the cooling fin 46. A temperature probe 48 is installed inside the housing 41. The magnetic stirring motor 43, the semiconductor cooler 47, and the temperature probe 48 are all electrically connected to the temperature controller 5.

[0028] Specifically, the top of the vessel body 11 is provided with a feed inlet 18, and the bottom of the vessel body 11 is provided with a discharge outlet 19.

[0029] In this embodiment, the plant extract is added through the inlet 18, and after distillation, the outlet 19 is used to discharge the waste liquid.

[0030] Specifically, the top of the water jacket 13 is provided with a heat source inlet 110, and the bottom of the water jacket 13 is provided with a heat source outlet 111.

[0031] In this embodiment, hot water is introduced into the water jacket 13 through the heat source inlet 110 to control the temperature inside the distillation kettle 1. After distillation is completed, the hot water is discharged from the heat source outlet 111.

[0032] Specifically, the top of the vessel body 11 is provided with a steam outlet 112, a viewing window 113 and a first reflux port 114, and the lower part of the tower body 31 is provided with a steam inlet 33 and a second reflux port 34 respectively. The steam outlet 112 is connected to the steam inlet 33 through a pipe, and the first reflux port 114 is connected to the second reflux port 34 through a pipe.

[0033] In this embodiment, after the plant extract is heated in the distillation kettle 1, the water vapor containing aromatic components is preliminarily purified by the primary purification tower 3. The core function of the bubble cap tray 32 inside is to serve as a gas-liquid mass transfer contact element. By dispersing the gas through the bubble cap to form small bubbles, the gas-liquid contact area is increased to improve the mass transfer efficiency. This structural feature makes it have higher separation efficiency and operational stability when processing complex materials.

[0034] Specifically, the top of the tower body 31 is provided with a steam outlet 35, and the top of the shell 41 is provided with a pipe interface 49, which is connected to the steam outlet 35 through a pipe.

[0035] In this embodiment, water vapor is introduced from the steam outlet 35 into the cooler 4 for cooling treatment.

[0036] Specifically, the lower part of the housing 41 is provided with a liquid outlet 410, one end of the serpentine coil 42 is connected to the pipe interface 49, and the other end is connected to the liquid outlet 410.

[0037] In this embodiment, when the water vapor in the serpentine coil 42 condenses, it becomes a liquid consisting of a layer of essential oil and a layer of hydrosol, which is then discharged through the outlet 410.

[0038] During use, the plant extract is added through inlet 18, and hot water is introduced into the water jacket 13 through heat source inlet 110 to control the temperature inside the distillation kettle 1. After being heated in the distillation kettle 1, the plant extract generates water vapor. The water vapor containing aromatic components undergoes preliminary purification in the primary purification tower 3. The core function of the bubble cap tray 32 inside the tower is to act as a gas-liquid mass transfer contact element. By dispersing the gas through the bubble cap, small bubbles are formed, increasing the gas-liquid contact area and improving the mass transfer efficiency. This structural feature gives it higher separation efficiency and operational stability when processing complex materials. The extract then enters the cooler 4 for cooling. A semiconductor cooler 47 (mainly composed of a semiconductor cooling chip, a heat sink, and a cooling fan; the heat sink is installed on the hot side of the semiconductor cooling chip, and the cooling fan is installed on the heat sink to dissipate heat from the hot side) is installed on the cooler 4. The cooling plate 46 is used to lower the temperature of the hot water exchanger. The magnetic stirring motor 43 drives the stir bar 44 to stir the hot water exchanger (utilizing the principles of magnetic fields and vortices; when the magnetic stirring motor 43 is energized, it generates a rotating magnetic field that drives the stir bar 44 to move in a circular motion, thereby causing the liquid inside the shell 41 to form a vortex, thus achieving the purpose of stirring the liquid). This improves its fluidity and can quickly remove the heat of the water vapor in the serpentine coil 42 for condensation, turning it into a liquid consisting of a layer of essential oil and a layer of hydrosol that is discharged. The temperature controller 5 is used to adjust and control the temperature to ensure that the hot water exchanger inside the cooler 4 is kept within the set temperature range. The temperature sensor 48 is used to monitor the water temperature inside the cooler 4 in real time. When the water temperature exceeds the set threshold, the temperature controller 5 is used to adjust the cooling temperature of the semiconductor cooler 47 and the speed of the magnetic stirring motor 43 to achieve a rapid heat exchange and cooling effect.

[0039] In summary, in this essential oil distillation equipment, after the plant extract is heated in the distillation kettle 1, the water vapor containing aromatic components undergoes preliminary purification in the primary purification tower 3, and then enters the cooler 4 for cooling. By installing a semiconductor cooler 47 and a cooling plate 46 on the cooler 4, the temperature of the heat exchange water is reduced. The magnetic stirring motor 43 drives the stir bar 44 to stir the heat exchange water, improving its fluidity. This allows the heat of the water vapor in the serpentine coil 42 to be quickly removed, resulting in condensation and the discharge of a liquid consisting of a layer of essential oil and a layer of hydrosol. The temperature controller 5 is used to regulate and control the temperature, ensuring that the heat exchange water inside the cooler 4 remains within the set temperature range. The temperature sensor 48 is used to monitor the water temperature inside the cooler 4 in real time. When the water temperature exceeds the set threshold, the temperature controller 5 is used to adjust the cooling temperature of the semiconductor cooler 47 and the rotation speed of the magnetic stirring motor 43 to achieve a rapid heat exchange and cooling effect.
