The utility model relates to the technical field of chemical separation and evaporation and distillation applications, and specifically provides a short-range evaporation device with a scraper that absorbs the advantages of traditional simple distillation and industrial short-range evaporators, and greatly increases the evaporation area by means of an inner rotating scraper so that the material forms a film on the inner wall of the evaporation chamber, and at the same time improves the heat transfer efficiency, thereby improving the efficiency and selectivity of the evaporation distillation. At the same time, by using feed and discharge pumps, the process is continuously operated and can be widely used in chemical separation and evaporation and distillation, as well as evaporation and distillation of organic and bioactive materials, especially the separation and extraction of traditional Chinese medicine and plant essential oils.
