REVOLVING GRAIN DRIER Russian patent published in 2003 - IPC

FIELD: farming. SUBSTANCE: proposed grain drier includes frame on which ring-shaped drying chamber is mounted which is provided with outer and inner guards, drive for rotation around axis of platform whose bottom is made in form of perforated disk; bearing and thrust rollers are secured to bearing tubes. Platform is mounted on bearing rollers smoothly located over circumference. Grain drier includes also material loading and unloading units which are mounted above perforated disk and L-shaped cutoff baffle mounted above perforated disk; transporting working member is mounted under said baffle. Besides that, drier is provided with air duct for delivery of heat carrier. Secured concentrically relative to axis above swivel platform are two cylindrical shells of various diameter which perform function of outer and inner guards. Inlet and outlet holes of loading unit are rectangular in shape. Length of inlet and outlet holes are related as 1:5-15. Length of outlet hole of loading unit is equal to distance between inner surface of outer shell and outer surface of inner shell. Side walls of loading unit are provided with telescopic adjusting plates secured on them; width of these plates is equal to width of lower portion of loading unit. Size of perforations of detachable disk ranges from 0.3 to 2 mm. Outlet hole of air duct is located below perforated disk and is more than its inlet hole. Upper web of cutoff baffle is telescopic; extensible part is turnable towards center of drier through angle of 12 deg. or movable relative to part of upper web. Height of vertical web is equal to 1/4-2/3 of height of upper surface of perforated disk above lower surface of loading unit. Unloading unit is located under perforated disk. Bearing rollers are mounted on each bearing pedestal and thrust bearings are mounted on each 3rd and 4th pedestal. EFFECT: extended functional capabilities; improved quality of dried material; increased productivity. 7 cl, 9 dwg
