Description

Technical Field

[0002] Angelica sinensis is a traditional Chinese medicine with both nutritional and medicinal value. It is the dried root of the Apiaceae plant, and is traditionally found in Minxian County, Gansu Province, and Sichuan Province. Modern clinical pharmacological studies have shown that angelica sinensis has benefits such as nourishing and promoting blood circulation, regulating menstruation, and alleviating pain. Its volatile oil, one of the main components of angelica sinensis, is complex and diverse, with ligustilide being its primary constituent. Angelica sinensis volatile oil has various pharmacological effects, including antibacterial, anti-inflammatory, anti-Alzheimer's, and anti-cardiovascular effects.

[0003] With the development of modern science and technology, the research and development of natural medicines have become increasingly in-depth. Different extraction methods for angelica have emerged, such as steam distillation extraction, supercritical CO2 extraction, microwave-assisted technology, etc. People can choose appropriate extraction methods according to different needs and conditions to improve the extraction efficiency and quality of angelica volatile oil.

As the raw materials in the raw material tank 82 decrease, the quantitative detection mechanism 86 will make the raw material tank 82 move upward. When the trigger plate 83 touches the trigger 85, the solenoid valve 87 is closed, and the addition of raw materials stops. Then, the distillation device 2 is closed, the first cooling water inlet 34 and the second cooling water outlet 45 are connected to the cold water pump, the device is started, the working pressure and temperature are set, and the equipment starts working. The distilled gas passes through the distillation inlet pipe 36 and enters the straight cooling device 3. The liquid is cooled and flows into the cooling device through the distillation outlet pipe 46 for sufficient cooling. The liquid then flows back into the distillation cylinder 21 through the reflux pipe 49 for secondary distillation and purification. The liquid then flows to the bending cooling device 4 through the above steps. The liquid flows into the filter device 5 from the bending cooling device 4 through 54 and the filter liquid inlet pipe. The liquid is filtered by the filter device 5 to filter out some residues. The liquid then flows into the separation device 6 through the separation liquid inlet pipe 62. Water and volatile oil are separated in the separation device 6. The water flows out from the liquid outlet tap 63, and the volatile oil passes through the liquid storage valve 64 and flows to the liquid storage tank 71 for storage. When the volatile oil needs to be used, it can be collected through the liquid outlet 72.
