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.
