[0001] The invention relates to the technical field of essential oil extraction equipment, in particular to essential oil extraction equipment. Background Art

[0002] Plant essential oil distillation and extraction equipment is a key technical equipment that uses water vapor to extract aromatic compounds from plants. Its core principle is to use high-temperature water vapor to heat the volatile organic compounds in the plant material to evaporate with the water vapor, and then collect the essential oil through condensation. The distillation device is easy to operate and is widely used in industrial-scale production. The extraction efficiency is improved by steam heating.

[0003] The prior art also has the following defects during use: The essential oil extraction equipment in the prior art does not have an ideal utilization rate of steam. When steam fumigating plant materials, it is easy to cause the temperature of the local plant materials to be relatively high, thereby causing uneven extraction of aromatic compounds in the plant materials, affecting the quality of the essential oil extracted by the device. When the essential oil extraction equipment in the prior art cools and liquefies the essential oil by condensation, the contact area between the water vapor carrying the essential oil and the condenser is limited, which causes the essential oil to fall with the condensed water without being completely cooled, which easily causes secondary volatilization of the essential oil, thereby reducing the quality of the essential oil extracted by the device.

The electromagnetic valve 604 is opened and closed in sequence, so that the high-temperature water vapor forms a spiral upward steam vortex inside the distillation component 6, so that while fumigating the plant materials, the plant materials can be loosened and the gaps between the plant materials can be maintained, which can enhance the rectifying effect of the high-temperature water vapor on the plant materials. The side nozzle 601 can guide the internal high-temperature water vapor so that the high-temperature water vapor is discharged from the side to the bottom of the distillation component 6. The jet hole 607 sprays out, thereby facilitating the distillation of the plant material near the side, expanding the heating area of ​​the plant material by the high-temperature steam, and improving the distillation efficiency of the plant material by the high-temperature steam.

The motor 101 can rotate after being energized, thereby driving the driving shaft 104 and the components at its bottom to rotate, and the crushing paddle 103 can rotate synchronously with the driving shaft 104, thereby chopping the plant material entering the crushing trough 1, and cooperating with the particle board 102 to cut the plant material into plant fragments with a diameter of three to five centimeters, thereby facilitating the distillation and extraction of aromatic compounds in the plant.

[0020] Furthermore, a lower barrel 204 is fixedly installed inside the upper shell 2, and the top of the lower barrel 204 is fixedly connected to the control valve 205.

The steam connecting pipe 203 is connected to the steam generator, and the condensation hood 4 is cooled by powering on the control box 202, so that the temperature of the condensation hood 4 decreases, and at the same time, the high-temperature water vapor enters the aeration pipe 603 through the guide pipe 608, and the switch of the aeration pipe 603 is controlled by the solenoid valve 604, so that the high-temperature water vapor is ejected from the bottom jet hole 605 in turn, and at the same time, part of the high-temperature water vapor is ejected from the bottom jet hole 605. Steam enters the side nozzle 601 and is ejected from the lateral jet hole 607, so that the plant raw material is heated by the high-temperature water vapor at the bottom and the side at the same time, so that the aromatic compounds inside the plant raw material evaporate with the high-temperature water vapor, and the extracted high-temperature water vapor and essential oil gradually rise until they come into contact with the inner wall of the condensation hood 4, gradually cool down and liquefy on the inner wall of the condensation hood 4, and flow downward along the inner wall of the condensation hood 4, and flow downward in a spiral under the guidance of the guide groove 401 until it drips on the bottom of the lower shell 3, completing the extraction of the essential oil inside the plant raw material. After the extraction is completed, the distilled plant waste is discharged from the discharge pipe 304 to the collecting tank 501, and the essential oil inside the lower shell 3 is discharged through the drain valve 302, completing the extraction of the plant essential oil.
