[0028] The following are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention.

[0029] An essential oil vacuum extraction device with uninterrupted sampling, such as Figures 1 to 3 As shown, it includes a distillation tank 1, a condenser 2, an oil-water separator 3, a heating device and a vacuum device. The distillation tank 1 is connected to the condenser 2, the condenser 2 is connected to the oil-water separator 3, the heating device is arranged on the distillation tank 1, the vacuum device is connected to the distillation tank 1, and the oil-water separator 3 is connected to a continuous sampling mechanism 6. The continuous sampling mechanism 6 includes a sampling connection pipe 61, a sampling control valve 62, a sampling barrel 63, a sampling ventilation valve 65 and a sampling ventilation pipe 64. The upper end of the sampling connecting pipe 61 is connected to the lower part of the oil-water separator 3, the lower end of the sampling connecting pipe 61 is connected to the upper part of the sampling barrel 63, the sampling control valve 62 is arranged on the sampling connecting pipe 61, the first end of the sampling ventilation pipe 64 is connected to the sampling connecting pipe 61 or the sampling barrel 63, the sampling ventilation valve 65 is arranged on the sampling ventilation pipe 64, the lower part of the sampling barrel 63 is connected to the sampling pipe 66, and the sampling valve 67 is arranged on the sampling pipe 66.

[0030] Traditional essential oil vacuum extraction equipment cannot take samples during the extraction process, and often needs to wait for the extraction to be completed or stopped before taking samples, which makes it difficult to adjust the proportion of spice plants, takes a long time to debug, and has low production efficiency. The utility model uses an uninterrupted sampling mechanism 6 to take samples during the vacuum extraction process, so that the extraction situation can be grasped in real time, which is convenient for accurately adjusting the proportion of spice plants, reducing debugging time, improving production efficiency, and reducing production costs. During extraction, the sampling control valve 62 is kept open. When sampling is required, the sampling control valve 62 is closed and the sampling vent valve 65 is opened to relieve the pressure in the sampling barrel 63. Finally, the sampling valve 67 is opened to take samples without affecting the extraction.

[0031] Specifically, the vacuum device includes an extraction vacuum pump 51 and a sampling vacuum pump 52. The extraction vacuum pump 51 is connected to the upper part of the oil-water separator 3 through a vacuum connecting pipe 31. A vacuum control valve 32 is provided on the vacuum connecting pipe 31. The sampling vacuum pump 52 is connected to the second end of the sampling ventilation pipe 64. During extraction, the sampling control valve 62 is kept closed. After the temperature in the distillation tank 1 reaches 100°C through the heating device, the extraction vacuum pump 51 is started to evacuate until the temperature in the distillation tank 1 drops to 50°C. Then, the extraction is waited for 30 minutes, and finally the pressure is released and the temperature is lowered to take out the essential oil and spice plants.

[0032] When sampling is required, the sampling vacuum pump 52 is started and the sampling vent valve 65 is opened. The sampling barrel 63 is evacuated by the sampling vacuum pump 52 until the vacuum degree in the sampling barrel 63 is the same as the vacuum degree in the oil-water separator 3. Then the sampling control valve 62 is opened to allow the essential oil to flow into the sampling barrel 63. Finally, the sampling control valve 62 and the sampling vacuum pump 52 are closed. After the sampling barrel 63 is depressurized, the sampling valve 67 is opened for sampling. By setting the sampling vacuum pump 52 to evacuate the sampling barrel 63 alone, the sampling control valve 62 can be kept closed during extraction to prevent the water or essential oil in the oil-water separator 3 from entering the sampling barrel 63, thereby facilitating the reflux of the water separated by the oil-water separator 3. In addition, when pre-vacuuming before extraction, the extraction vacuum pump 51 and the sampling vacuum pump 52 can be started at the same time to evacuate, thereby increasing the pre-vacuum speed and further improving production efficiency.

[0033] Specifically, the first end of the sampling vent pipe 64 is connected to the middle of the sampling connection pipe 61, and the sampling control valve 62 is arranged between the sampling vent pipe 64 and the oil-water separator 3. When the sampling control valve 62 is closed, the connection between the oil-water separator 3 and the sampling vacuum pump 52 can be directly cut off, which simplifies the structure and facilitates installation.

After extraction, the pressure is released by opening the pressure relief valve 34, so that the distillation tank 1 is opened to facilitate the next material filling.

[0035] Specifically, a sampling pressure gauge 68 is provided on the upper part of the sampling barrel 63, and a separation pressure gauge 35 is provided on the upper part of the oil-water separator 3. When sampling, the sampling vacuum pump 52 is used and the sampling vent valve 65 is opened. The sampling barrel 63 is evacuated by the sampling vacuum pump 52 until the pressure values ​​of the sampling pressure gauge 68 and the separation pressure gauge 35 are the same. Then, the sampling control valve 62 is opened to allow the essential oil to flow into the sampling barrel 63. The pressure values ​​of the sampling barrel 63 and the oil-water separator 3 are real-timely grasped by the sampling pressure gauge 68 and the separation pressure gauge 35. The operation is simple.

A gas supply pipe 131 is connected between the condenser 2 and the distillation pot cover 13. The reflux pipe 71 passes through the outer tank body 11 and is connected to the upper part of the inner tank body 12. The inner tank body 12 is heated at a low temperature in water insulation through the heating chamber 14 to prevent burning. The spice plants are placed in the material hanging basket 121, and the material hanging basket 121 is located in the middle of the inner tank body 12 through the material installation platform 122 to make it heated more evenly.

[0038] Specifically, the upper edge of the outer tank body 11 is fixedly connected to the outer side wall of the inner tank body 12, the distillation pot cover 13 is set on the upper part of the inner tank body 12, the distillation pot cover 13 is provided with a distillation pressure gauge 132, a safety valve 133, a feeding port 134 and a cover opening hook 135, and a slag discharge pipe 123 is provided at the lower part of the inner tank body 12, the slag discharge pipe 123 extends downward from the outer tank body 11, and a slag discharge cover 124 is provided at the lower end of the slag discharge pipe 123.

[0039] Specifically, the heating device includes an inner heating coil 41 and a steam generator.

Both ends of the inner heating coil 41 extend out of the outer tank body 11 and are connected to the steam generator. The heating chamber 14 is connected to the steam generator through a steam pipe. The heating liquid in the heating chamber 14 is heated by the steam generator to achieve the purpose of low-temperature heating.
