Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hot reflux extraction tanks, in particular to a hot reflux extraction tank with automatic residue discharging function. BACKGROUND

[0002] With the development of society, the traditional Chinese medicine industry has ushered in an opportunity for vigorous development. In the production process of medicinal materials, the extraction of effective components is a key link to ensure the quality and efficacy of medicinal materials. The hot reflux extraction tank, as an efficient extraction equipment, is widely used in the production of medicinal materials. It vaporizes the solvent (usually water or ethanol) by heating, and the vapor rises and contacts the medicinal materials, dissolving the effective components in the medicinal materials. Then, the vapor is liquefied and returned to the tank by the condensing device, forming a cycle of extraction. This method can fully utilize heat energy, improve the extraction rate of effective components, and reduce solvent consumption, which is in line with the concept of energy saving and environmental protection. It is of great significance to ensure the quality of medicinal material extraction and improve production efficiency.

[0003] However, the existing hot reflux extraction tank has some problems in use. On the one hand, most of the existing equipment adopts batch production mode, that is, each extraction needs to go through the steps of feeding, extraction, discharging, cleaning, etc. After completing a batch of extraction, the next batch of operation can be carried out. This production method makes the idle time of the equipment longer, cannot realize continuous production, greatly reduces the production efficiency, and is difficult to meet the demand of large-scale medicinal material production. On the other hand, after each extraction is completed, a large amount of medicinal material residue is left in the tank. These residues need to be cleaned manually, which not only wastes time and effort, but also increases the labor intensity of the operators. In addition, frequent manual cleaning also prolongs the production interval time, further reduces the utilization rate of the equipment, and restricts the continuity and efficiency of medicinal material production.
