| Abstract: | Structure, character, principle and application of reduced pressure concentration device are introduced and a comparison on the concentration efficiency and the effect on the content of heating-sensitivity components between the methods of the reduced pressure concentration and rotary thin film concentration is made. The result shows that the reduced pressure concentration has the advantages of large instrument capacity, fast speed, shorter time for heating the concentrated solution, simple operation and high efficiency etc. |
