摘要： Process for coating tablet cores or the like with a film, comprising moving a plurality of tablet cores about within a container, introducing a current of gas through an outlet into said container into the body of moving tablet cores in such manner that a substantially tablet-free gas space is formed just beyond said gas outlet which is surrounded by said moving tablet cores, and spraying a suspension or solution of film-forming material into said current of gas. The process combines the best features of conventional coating processes in a rotating dragee kettle with the advantages of a fluidized bed coating operation.

摘要： 1. IN THE PROCESS OF COATING TABLET CORES OR THE LIKE WITH A COATING COMPRISING PLACING SAID CORES IN A CONTAINER, ROTATING SAID CONTAINER TO MOVE SAID CORES ABOUT, SUPPLYING A SUSPENSION OR SOLUTION OF COATING MATERIAL TO SAID CONTAINER TO COAT SAID CORES AND SUPPLYING A DYRING GAS TO SAID CONTAINER TO DRY THE COATING ON SAID CORES, THE IMPROVEMENT WHICH COMPRISES INTRODUCING SAID DRYING GAS INTO THE BODY OF MOVING TABLET CORES BELOW THE LEVEL THEREOF IN SUCH MANNER THAT A SUBSTANTIALLY TABLET-FREE GAS SPACE IS FORMED JUST BEYOND THE POINT OF DISCHARGE OF SAID GAS, SAID GAS BEING DIRECTED IN THE MAIN DIRECTION OF MOVEMENT OF THE TABLET CORES, SPRAYING OF SAID COATING MATERIAL INTO SAID GAS SPACE TAKING PLACE IN A DIRECTION SUBSTANTIALLY PARALLEL TO THE DIRECTION OF DISCHARGE OF SAID GAS.
