SHAFT-TYPE AIRSLIDE DRIER Russian patent published in 2014 - IPC F26B17/14 

FIELD: heating, drying.

SUBSTANCE: invention refers to machines for drying of loose, slow-loose and granulated materials. A shaft-type airslide drier includes a loading neck, a drying chamber with wedge-shaped ducts located one under another, an unloading neck, and shaft walls with waste air discharge openings. A wall of each drying duct is bent at the height of 100-200 mm from a perforated load-carrying partition wall throughout its length and forms a pocket for removal of waste air with an inclination angle of a side wall of 35-50° in a vertical plane, which provides obstacle-free flow of grain heap from a pocket and 5-15° in a horizontal plane for equalisation of static pressure above the grain layer; pockets are tightly closed with a confuser for collection of waste air.

EFFECT: invention is aimed at intensification, improvement of a uniform and reliable drying process of grain and other loose materials; reducing energy consumed for drying; simpler structure, manufacturability; reducing room air dust content.
