Volatile oil stable collection device in artemisia carvifolia extraction process and control method thereof

Abstract

The invention discloses a volatile oil stable collection device in the artemisia carvifolia extraction process and a control method thereof. The collection device comprises an extraction tank, a steam inlet pipe communicated with the extraction tank, a steam heating valve and a through steam inlet valve arranged on the pipe, a condenser communicated with the extraction tank, a cooling water valve used for adjusting the cooling water flow rate of the condenser, an oil-water separator, a condensate water inlet pipe connected between the condenser and the oil-water separator, an oil collector arranged at the opening of the oil-water separator, an oil collection pipe, a U-shaped pipe used for recycling condensate, an extraction tank return valve arranged on a pipeline between the U-shaped pipe and the extraction tank, an oil collector venting valve, and a U-shaped pipe venting valve. The oil collection pipe has an oil collection opening, and has an oil collection pipe liquid outlet valve disposed outside the oil collector. The device further comprises an oil and water level detection probe disposed in the oil collector and used for detecting the oil and water level. The oil collector venting valve, the oil collection pipe liquid outlet valve and the extraction tank return valve make adjustment according to the detection result of the oil and water level detection probe.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine pharmacy, in particular to a stable collection device for volatile oil in the extraction process of Artemisia annua and a control method thereof. Background technique [0002] Reduning injection is a new drug independently developed by Jiangsu Kangyuan Pharmaceutical Co., Ltd. It is a compound injection of traditional Chinese medicine, which is extracted and refined from three traditional Chinese medicines of honeysuckle, gardenia and Qinghao. [0003] The extraction of volatile oil of Artemisia annua is an important link in the production process of Reduning injection, which plays an important role in the safety, effectiveness and stability of the final product. [0004] The traditional method of extracting the volatile oil of Artemisia annua is: after feeding into the extraction tank used for distillation, manually open the straight-through steam valve connected with the extraction ta...

Problems solved by technology

However, the system is affected by the complexity of the steam system and the proficiency of manual operation. The parameters closely related to the quality such as the liquid level of the condensate, the liquid level of the oil-water interface, and the temperature of the reflux liquid cannot be effectively controlled, which seriously affects the extraction process of the volatile oil of Artemisia annua. Stability and stability of the quality of Artemisia annua volatile oil
