LOOSE MATERIAL DRIER Russian patent published in 1994 - IPC

FIELD: drying technology. SUBSTANCE: drier has a perforated screen, a case and an air duct coaxially mounted in the case which form an annular chamber. The drier also has a fan and a valve mounted in the air duct for moving along it. A spring which is a high-potential electrode of a high-frequency capacitor is mounted in the chamber. The spring is connected to a current source by a flexible link. The spring is mounted for extension and compression synchronously with the valve depending on the level of the loose material in the bunker. The case and the air duct are low-potential electrodes of the high-frequency capacitor. EFFECT: improved structure. 2 dwg
