In specific operation, the raw material liquid medicine can be poured into the raw material box 2 for storage by screwing out the stopcock 9. In the process of double-effect concentration processing of the raw material liquid medicine, by opening the liquid inlet valve 11, the raw material liquid medicine in the raw material box 2 will continuously flow into the filter cartridge 4 through the liquid inlet pipe 10, so that the raw materials entering the filter cartridge 4 fall into the truncated cone coarse filter cover 20 and the truncated cone.

The raw material liquid entering the fixed box 14 enters the first-effect heating chamber 5 and the second-effect heating chamber 7 respectively through the infusion pipe 15 and the three-way pipe. Then, by using the first-effect heating chamber 5, the first-effect evaporation chamber 6, the second-effect heating chamber 7 and the second-effect evaporation chamber 8 together, the raw material liquid can be subjected to double-effect concentration processing.
