Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine liquid preparation, and in particular to a continuous closed separation and filtration device for traditional Chinese medicine liquid. Background Art

[0002] In the traditional preparation process of Chinese medicine liquid, the separation and filtration of the liquid is a key step, which directly affects the purity and quality of the final product. With the continuous development of Chinese medicine pharmaceutical technology, the requirements for the separation and filtration of liquid medicine are getting higher and higher. Traditional filtration devices often have the following problems: 1. Low filtration efficiency: Generally, multiple filtrations are required to achieve the expected purity; 2. Discontinuous operation and poor airtightness: When the filter screen is blocked, the existing separation and filtration equipment often needs to open the equipment for cleaning or replacement of the filter screen. The poor sealing makes it easy for the liquid medicine to be exposed to the external environment, resulting in the liquid medicine being contaminated or the efficacy being reduced. At the same time, the operation is discontinuous, which reduces production efficiency. 3. Difficulty in cleaning and replacing filter materials: The replacement and cleaning of filter materials in traditional devices are often difficult, which increases maintenance costs and time.
