Abstract: A capsule dusting system is designed to expose capsules to a dusting agent in a controlled manner. The system incorporates a tumbling basket positioned within an enclosure. The tumbling basket is loaded with capsules and is rotatably connected to a drive shaft. A dust injection system meters the dusting agent into the dust injection system. The dust injection system may include a dusting injector that translates between two positions. At one position, the dusting injector is loaded with dusting agent by a powder supply system. At the other position, the dusting injector is positioned to inject the dusting agent into the tumbling basket. A gas is fluidly connected to the dusting injector to cause the dusting agent to disperse into the tumbling basket. The enclosure contains the dusting agent within the system to reduce the environmental, health, and safety hazards associated with airborne particulates.

Abstract: The present invention provides a method and apparatus for dry coating solid dosage forms. The method includes the steps of placing solid dosage forms in a rotatable, electrically grounded housing, and spraying a film forming polymer powder composition into the housing during rotation thereof to form a polymer coating on the solid dosage forms, the polymer powder composition being sprayed using an electrostatic spray gun, and curing the coated solid dosage forms.

Abstract: A method of coating tablets with a high molecular weight polymer wherein the high molecular weight polymer is suspended in a non-solvent, non-aqueous liquid carrier. The liquid carrier may include a low-viscosity binder. Preferably, the binder is included in concentrations of around 1-10% by weight in solution in the carrier. The high molecular weight polymer may be micronized prior to its suspension in the liquid carrier. Once suspended, the liquid is introduced into a spray coating machine such as a partially or fully perforated pan system wherein the tablets are coated as desired.

Abstract: A method and computer program product for simulating a pan coating process estimates at least one of tablet coating uniformity or coated tablet weight uniformity for tablets within a tablet bed of a pan. The simulation includes obtaining a plurality of parameters associated with the pan coating process, selecting tablet paths for each cycle of a simulation tablet in the tablet bed, determining a coating amounts for the tablet based on selected tablet paths, determining cycle times for the tablet, and summing the determined coating amounts and cycle times for the tablet. The simulation is repeated for each of a defined number of simulation tablets representing the tablets within the tablet bed to determine tablet coating uniformity and/or coated tablet weight uniformity for the tablets. Tablet paths and/or cycle times are determined randomly, e.g., in accordance with a Monte Carlo method.

Abstract: A system for coating tablets and other small articles is provided. The system is comprised of an elongate housing containing a drum journalled for rotation about a horizontal axis. The drum has two open ends that receive and discharge a supply of tablets respectively. The drum is rotated about the axis by a drive means to tumble the tablets and advance the tablets through the drum. The system also includes a system for delivering a selected amount of coating to the tablets while they are being tumbled and a feeder for continually feeding tablets at a first end of the housing. The system employs a weir plate for maintaining a depth of tablets within the drum and for controlling the time that the tablets remain in the drum. Finally, the system has a tablet discharge region for receiving tablets for discharge.

Abstract: An apparatus for coating seeds and particulate material includes an elongated tray operably mounted on a support frame with a motor for oscillating the tray to move particulate material from a rearward end to a forward end therealong. The tray includes a perforated support surface with a saw-toothed cross-sectional shape such that the particulate climbs the inclined tread of each sawtooth and drops from the forward end of one tread to the rearward end of an adjacent tread to form a “curtain”. A plurality of spray nozzles are located over the tray to direct coating solution onto the seeds as they move along the tray. Preferably, the nozzles direct spray towards the curtain of falling seeds between the treads. An upper housing on the support frame includes an air plenum which directs air downwardly onto the seeds on the support surface and through the perforated support surface to a second air plenum formed under the support surface.

Abstract: To coat a surface of a medical implant such as an organ part or a synthetic prosthesis with a coating of living cells, the implant is inserted and fixed into a receiving container which is at least partially filled with a nutritive liquid medium containing the coating cells in suspension. Then the receiving container is rotated respectively about two distinct rotation axes, whereby preferably the two rotation motions are independently controllable and the two axes are substantially perpendicular to each other. Each of the two rotation motions can be a continuous rotation through 360°, or a stepwise intermittent rotation through successive rotational angle steps. The parameters of the two rotations about the two axes can be combined as needed for a particular application, for example a continuous rotation about one axis combined with a stepwise rotation about the other axis. The time period and rotational speed of each rotation can also be independently controlled.
