Problems solved by technology

[0002] At present, in the pharmaceutical, chemical and food industries, most of the technical improvements related to the extraction and concentration of active ingredients are only aimed at each individual step, such as the application of microwave, ultrasonic and other means to speed up the extraction efficiency in the extraction stage, and the proposed method for the concentration stage Microwave concentration and vacuum concentration, etc.; and most domestic manufacturers design and manufacture these two processes separately, and the operation is also step-by-step, resulting in a great waste of extractants and materials, and volatile extraction Agents are likely to pollute the environment
