Apparatus for coating tablets

摘要: A fluidized bed apparatus for applying a coating liquid onto the surface of particles includes vertically disposed cylindrical product container having peripheral wall, at least one partition defining centrally located up region and peripherally down region. The further an upper end connected to expansion chamber lower including orifice plate plurality openings passage air or gas. nozzle is through adapted generate spray upwardly into bed. Particles within circulate spray, between inwardly directed discharge jets are positioned along periphery generally adjacent plate. source pressurized gas provide radially flow so that wall displaced towards
