Description

Technical Field

[0001] The utility model belongs to the technical field of traditional Chinese medicine concentration, in particular to a device for extracting and concentrating traditional Chinese medicine with ethanol. Background Art

[0002] The rationality, energy saving, cleaning convenience and extraction efficiency of the Chinese medicine ethanol extraction device design are important factors affecting the Chinese medicine ethanol extraction process. The existing extraction devices still have certain defects in controlling production continuity, production capacity, energy saving and consumption reduction, and extraction rate.

[0003] Specifically:

[0004] 1. Poor production continuity. The ethanol extraction process requires soaking extraction, concentration, alcohol precipitation, ethanol recovery, ethanol blending and cleaning. In order to ensure the continuity of production, a reasonable pipeline connection structure needs to be designed to ensure the effective and orderly connection between one process and the next. It is important to ensure the automatic transmission of materials without human intervention. Some existing devices cannot guarantee the continuity of production and require human intervention in the middle to proceed to the next step.

[0005] 2. In terms of energy saving and consumption reduction, ethanol is needed in the process of ethanol extraction of traditional Chinese medicine. During the design of the device, ethanol needs to be recycled and reused to ensure the maximum utilization of raw materials. The existing equipment is still lacking in ethanol recovery and utilization rate, and there is a lot of room for improvement;

[0006] 3. In terms of production capacity and flexibility, in the existing equipment, when more extracts need to be concentrated, there is a certain gap in the production capacity supply, and it cannot meet the needs of more than two process extractions for the same batch of extracts; in terms of extraction rate, the existing equipment structure design, connection structure, and automation level have a lot of room for improvement, and the drug extraction rate needs to continue to improve.
