A rotatable drum has means for spraying a coating material onto a localized area of the cascading tablet surface of a tumbling bed of tablets being rotated in the drum. Means (not shown) is also provided for supplying drying air into the drum to dry the coated tablets. Open-ended tubular members mounted inside the drum, pass through the tumbling bed of tablets and completely beneath the localized area as the drum is rotated. The members thus extract tablets from the stagnant core of the tablet bed and distribute the extracted tablets onto the cascading tablet surface so as to hasten the coating process.
