Description

Technical Field

[0001] The utility model relates to the technical field of traditional Chinese medicine processing, in particular to a continuous dynamic extraction device for volatile oil. Background Art

[0002] In recent years, with the improvement of people's living standards, health and wellness have been paid more and more attention by people. Traditional Chinese medicine conditioning and treatment, which can treat both the symptoms and the root causes, are becoming more and more popular, thus contributing to the prosperity of the Chinese herbal medicine planting and processing market.

[0003] There are many Chinese herbal medicines containing volatile oils, most of which are aromatic, especially in the Lamiaceae, Apiaceae, Asteraceae, Rutaceae, Lauraceae, and Zingiberaceae families. Chinese herbal medicines containing volatile oils or volatile oils extracted from them mostly have the effects of sweating, regulating qi, relieving pain, inhibiting bacteria, and correcting flavors. They can evaporate at room temperature and can be distilled with water vapor. Volatile oils mostly have the effects of expectoration, cough relief, asthma relief, wind dispelling, stomachic, antipyretic, analgesic, and antibacterial and anti-inflammatory.

[0004] Currently, there are two main types of conventional volatile oil extraction: dry distillation: placing the medicine in a dry distillation device and heating it to make the volatile components slide out; wet distillation: mixing the medicine with water in a distiller and using water vapor to bring out the volatile components. Among them, the extraction tank, as a container for Chinese medicine and water, is the most important device in the equipment for extracting volatile oils.

[0005] The existing patent (publication number: CN207685229U) discloses a distillation tank and a volatile oil extraction device, which relates to the technical field of plant volatile oil extraction, including a tank body; a heating component is arranged on the outside of the tank body, and a steam component is arranged on the inside of the tank body; the steam component is arranged at the bottom of the tank body. In the above technical scheme, the inside of the distillation tank has a steam component, and the outside has a heating component, so when the plant is distilled, the outside of the distillation tank is also heated by the heating component on the basis of heating the plant by steam, and the enzymatically hydrolyzed plant is distilled by this double heating method. Steam rises from the bottom of the distillation tank and carries the volatile oil in the plant with it. In this process, the heating component can further heat the water soaked with the plant, which can effectively improve the extraction efficiency of the volatile oil. The inventor found the following problems in the prior art during the implementation of the utility model:

[0006] 1. When extracting volatile oil by distillation, the raw materials and water in the extraction tank are relatively static, the raw materials are piled together, the heating is uneven, the extraction efficiency is low, and the extraction is not thorough enough;

[0007] 2. The extraction tank is inconvenient to clean. When the extraction tank reaches the final stage of distillation, the internal water of the extraction tank is lost, and some raw materials remain on the inner wall and the bottom. Most of the raw materials will stick to the inner wall, which is inconvenient to clean later. Utility Model Content

During the extraction process, it always rotates slowly, and the heating is more uniform. The side cleaning rod 203 rotates synchronously, and the cleaning brush 204 scrapes and cleans the inner wall and the bottom of the tank body 101 to prevent the inner wall of the tank body 101 from sticking to the residue. Slag, when the tank body 101 is heated to a certain temperature, water vapor mixed with volatile oil enters the steam pipe 301, and is transmitted to the condenser 303 through the steam pipe 301. The condenser 303 is provided with cold water inside to accelerate the liquefaction of water vapor into liquid and discharge it into the water separator 304. After the extracted raw liquid is precipitated in the water separator 304, the water and oil are separated into layers. Turn the valve to discharge the water into one of the containers 305 first. After the water is discharged, the volatile oil is collected through another container 305.
