Description

technical field [0001] The invention belongs to the technical field of medicine extraction equipment, and in particular relates to an extraction tank and a medicine liquid extraction method with functions of heat recovery and dynamic circulation extraction. Background technique [0002] The extraction tank is a commonly used leaching and extraction equipment in the pharmaceutical and chemical industry, and is especially suitable for the leaching and extraction of components contained in plant products. The structure of the extraction tank includes a tank body and a jacket heating device. The top of the tank body has a feeding port, the lower part has a liquid medicine discharge port, the upper part of the high end of the tank body has a liquid inlet port or an exhaust port, and the lower part is the overall slag outlet of the pneumatic door. The door is equipped with a liquid filter device. At present, the extraction tanks in the prior art are all heated by jacketed steam, ...

AI Technical Summary

Problems solved by technology

At present, the extraction tanks in the prior art are all heated by jacketed steam, and are extracted by static extraction, which leads to slow heat transfer, high energy consumption, and poor thermal energy utilization during extraction; some extraction tanks are also located at the bottom It is heated directly by steam, so that the steam will cause pollution of the extract and medicine in the extraction tank

Therefore, there are technical problems such as high energy consumption, low extraction efficiency, high use cost, complex process and low production efficiency in the extraction tank of the prior art.
