MASS-TRANSFER APPARATUS Russian patent published in 1997 - IPC

FIELD: devices for conduction of mass-transfer processes in chemical, pharmaceutical, food and other industries concerned with treatment of solid phase with various liquids. SUBSTANCE: apparatus has horizontal sectional body accommodating longitudinally arranged shaft where mixing paddles and transfer buckets are mounted. Buckets for transfer of solid phase from section to section are installed for turning to attain fuller unloading of solid phase to next section in direction of solid phase motion. Axis of bucket rotation is displaced to the side opposite to bucket motion at a distance equals to 0.03-0.08 of radius of circumference inscribed by bucket center of gravity relative to axis of apparatus shaft. Angle of turn of bucket is regulated by stops located on bucket. EFFECT: improved design. 3 dwg
