Filtering-concentrating device and filtering-concentrating method for single-prescription traditional Chinese medicine decoction

Abstract

The present invention discloses a filtrating-concentrating device for filtering and concentrating a single prescription traditional Chinese medicine decoction and comprising a filtrating device (110) and a concentrating device (120) located downstream of the filtrating device (110). The filtering device (110) comprises a filter (21) and a filtering circulation pipeline (22) connected with the filter (21). And the concentrating device (120) comprises a roll type or disc tube type film concentrator (31) and a concentrating circulating pipeline (32) connected with the concentrator. The filter (21) and the concentrator (31) are arranged in axial abutment with each other, so that a clean liquid outlet of the filter formed at its axial end is in fluid communication with a first feed liquid inlet of the concentrator formed at its axial end facing the filter. According to the invention, filtrating and concentrating processes are integrated, so that purified liquid after filtrating circulation directly enters a film concentrating circulation system, and the efficiency is improved; parameterization customization of process parameters of different types of materials can be realized through parameter adjustment of the high-pressure pump; and components are easy to replace and convenient to install.

Description

technical field [0001] The invention relates to the technical field of concentration, in particular to a filter-concentration device for a single-prescribed traditional Chinese medicine decoction and a method for filtering and concentrating a single-prescribed traditional Chinese medicine decoction. Background technique [0002] The development of Chinese medicine has a long history, and the theory of Chinese medicine is extensive and profound. It is an important part of the traditional culture of the Chinese nation and has played an indelible role in the reproduction and survival of the Chinese nation. Since ancient times, traditional Chinese medicine has been taken mainly in the form of decoction orally. However, this method not only needs to spend considerable time and energy to decoct the Chinese medicinal materials before taking the medicine, but also the obtained Chinese medicinal soup is not only difficult to carry and difficult to preserve, so it can no longer meet t...

Problems solved by technology

However, for this method, due to the poor connection between the filtration and concentration process, it is necessary to pay extra manpower and material resources for material transfer and seriously affect the efficiency of the material concentration process.
