When the plant extract is sprayed onto the inner wall of the heating mantle 4 by atomization, the wavy shape of the inner wall of the heating mantle 4 allows enough heating surface to come into contact with the plant extract, thereby making the

evaporation efficiency of the plant extract is increased;

During the rotation of the inlet pipe 2, the stationary shaft 11 is caused by the

Inlet pipe 2 driven to the two scrapers 13 against the inner wall of the

To scrape the heating hood 4, and by scraping the scrapers 13 the on the

Inner wall of the heating mantle 4 remaining plant extract is scraped off by the scrapers 13, causing the plant extract to burn on the inner wall of the

Diameter of the baffle 16 is larger than the diameter of the opening on the

Front of the heating hood 4, the top of the baffle 16 is pivotable with a

Spindle 17 connected, the ends of the spindle 17 are on the inner walls of the

Evaporation container 1 attached on each side, the back of the baffle 16 is provided with a block 18, the block 18 is at the top of the V-shaped
