Common andrographis herb refining device

Abstract

The invention discloses a common andrographis herb refining device which comprises a mixing tank, a stirring pipe, rotary joints, a heating box, a delivery pump, a filter pressing assembly and a concentration assembly; a feeding pipe is arranged at the upper end of the mixing tank, and a discharging pipe is arranged at the lower end of the mixing tank; the stirring pipe has a hollow pipe body, twoends of the hollow pipe body are straight pipes, the middle part of the hollow pipe body is continuously bent, and a plurality of blades are arranged on the surface; the rotary joints are respectively arranged at the top and the bottom of the stirring pipe; the heating box communicates with the rotary joint at the bottom of the stirring pipe through a pipeline; the inlet end of the delivery pumpcommunicates with the heating box through a pipeline, and the outlet end communicates with the rotary joint at the top of the stirring pipe through a pipeline; the filter pressing assembly communicates with the discharging pipe; and the concentration assembly is used for concentrating a liquid filtered by the filter pressing assembly. According to the device, common andrographis herb is crushed and extracted in the mixing tank at the same time, so that the extraction period is shortened, a solution is heated uniformly through the rotating stirring pipe, the drug property of common andrographisherb is protected, the caking phenomenon in a tank body is avoided, impurities in the solution are filtered out through the filter pressing assembly, and the quality of a concentrated liquid medicineis improved.

Description

technical field [0001] The invention relates to the field of refining andrographis paniculata, in particular to a device for refining andrographis paniculata. Background technique [0002] Andrographis paniculata (Burm.f.) Nees is recorded in the Chinese Pharmacopoeia 2000 edition one, and is a commonly used traditional Chinese medicine. It has the effects of clearing away heat and detoxification, cooling blood and reducing swelling. At present, there are more than 10 kinds of Chinese patent medicines with Andrographis paniculata as the monarch medicine, including tablets, injections, nasal drops, etc. Its main active ingredients are lactone components such as andrographolide, dehydroandrographolide and deoxyandrographolide. [0003] The main refining process of Andrographis paniculata is alcohol extraction. Add Andrographis paniculata and mix it with absolute ethanol, filter after heating, and use a concentrator to concentrate the filtrate to obtain andrographolide extrac...

AI Technical Summary

Problems solved by technology

[0003] The main refining process of Andrographis paniculata is alcohol extraction. Add Andrographis paniculata and mix it with absolute ethanol, filter after heating, and use a concentrator to concentrate the filtrate to obtain andrographolide extract. The inventor found that during the refining process of Andrographis paniculata, Andrographis paniculata It needs to be crushed and then sent into the tank to be mixed with absolute ethanol. The process is not connected and the efficiency is low. In addition, the current heating tank is usually equipped with a heating wire or a heating layer on the inner wall of the tank. If local heating occurs too quickly, it is easy Agglomeration occurs inside the tank, causing trouble in cleaning
