SUPERHIGH FREQUENCY INSTALLATION FOR DRYING LOOSE MATERIALS Russian patent published in 2003 - IPC

FIELD: superhigh frequency installations for drying loose materials such as grains, sunflower seeds and so on. SUBSTANCE: installation includes vertical drying chamber 1 provided with charging device 2 and having in its lower portion discharging device 3, both devices have bins connected with chamber; superhigh frequency generator 9 with connection unit and blower 6. Novelty is drying chamber including cavities 16,8 for blowing under and suction respectively; casing arranged over generator 9 and provided with inlet and outlet branch pipes; injector 10 with two inlets and two outlets; cyclone 11; air flow splitter 12 having one inlet and two outlets. Drying chamber 1 is rectangular one; it has narrowed lower portion with apertured walls and with discharging device in the form of driven auger. Said lower portion is housed in casing restricting blowing under chamber. Drying chamber also includes charging device in the form of tubes with valves introduced in drying chamber and descended inside it by value equal to 0.1 -0.15 of height of chamber for forming suction cavity over dried material. Superhigh frequency generator 9 includes several (more than two) magnetrons with separate power sources and connection units arranged uniformly over casing on lateral surfaces of drying chamber. Outlet branch pipe of casing over generator 9 is connected with inlet of blower 6 whose outlet is connected with inlet of air flow splitter 12. One outlet of splitter 12 is connected with blowing chamber 16; its second outlet is connected with first inlet of injector 10 whose second inlet is connected with air cavity over dried material. Outlet of injector 10 is connected with inlet of cyclone 11. EFFECT: enhanced efficiency, improved ecology of installation. 1 cl, 2 dwg
