APPARATUS FOR PREPLANTING TREATMENT OF POTATO TUBERS IN ELECTROMAGNETIC FIELD Russian patent published in 1997 - IPC

FIELD: agriculture. SUBSTANCE: apparatus has charging vessel 1 positioned above feeding conveyor 2 provided with tension mechanism 3. Hopper 4 is positioned below drive shaft of conveyor 2. Load belt of conveyor is positioned in cavity of stator of three-phase electric engine 5, which is used to create electromagnetic rotating field. Dielectric U-shaped plate 6 is positioned on outer surface of electric engine housing surface and is adapted to carry positive flexible rubberized electrode 7 and negative flexible rubberized electrode 8. Feeding conveyor 2 is connected through V-belt drive with output shaft of electric drive 9. Planting material is simultaneously exposed to DC field and rotating electromagnetic field to promote tuber germination, growing and development of plants. EFFECT: increased yield by improved quality of treatment of planting material and reduced damage to tubers during processing. 1 dwg, 1 tbl
