DEVICE FOR LOOSE MATERIAL DRYING Russian patent published in 2011 - IPC F26B11/04 

FIELD: machine building.

SUBSTANCE: device for drying consists of rotating drum sinusoidal, generatrix of which is turned in direction of rotation along spiral. The drum is mounted on rotation axis with concentricity, while its generatrix is made with curvature radius where S is period of sinusoid (twist), A is amplitude of sinusoid. Additionally, the drum with sinusoid profile of generatrix can be made multi-sectional. Length of each section is equal to a period of sinusoid, while cross section is made in form of ellipse, large axis of which is inclined to rotation axis at angle β>arcsin(b/a), where b, a are small and big half-axis of ellipse.

EFFECT: raised efficiency of operation, reduced energy intensity of process, reduced damage of seeds of crop and forest plants.
