A dry powder coating apparatus for coating pharmaceutical solid dosage forms includes a housing; a drum coater; a powder coating system; a liquid spray system; a ventilation system; a heating system; a touch screen control panel; and an operation box. The drum coater may have a truncated cone on both sides, in which one side is opened and another side is closed. The drum coater is horizontally placed inside the operation box along its axis and fixed on a rotatable shaft and a motor drives the rotatable shaft and rotates the drum coater about its own axis.

A method for coating parts in a dip-spin process includes dipping the parts to be coated a coating liquid and spinning the parts in a planetary centrifuge in at least a first planetary basket arrangement and a second planetary basket arrangement, which each provide a maximum receiving volume. The planetary centrifuge includes a main rotor rotating about a main rotor axis of rotation. The at least two planetary basket arrangements rotate about their planetary axes of rotation, wherein the planetary axes of rotation are arranged on the main rotor spaced from the main rotor axis of rotation. The first planetary basket arrangement is rotated about its respective planetary axis of rotation in the opposite direction to the second planetary basket arrangement during centrifugation, and the filling of the receiving volume is carried out at up to 50% of the maximum receiving volume of the planetary basket arrangement.

A coating apparatus and method are disclosed for coating tablets with a film, in which the tables transit through a drilled first container where they are coated, then exit the first container and are removed from a rotating element provided on the periphery of a plurality of removal members that are spaced angularly apart from one another, in which each removal member removes a quantity of tablets, raises the removed tables as far as a certain height and then discharges the tablets into a chute that conveys the tablets into a second rotating drilled container, with delicate transfer of the coated tablets from one container to the next.

A method for coating bulk material uses a coating apparatus to produce a continuous flow of coated material having a predetermined stationary coating weight gain. Coating material is sprayed on the bulk material in two phases within respective first and second rotatable tubular containers of the coating apparatus. In the first rotatable container, the bulk material is partially coated with a pre-set weight gain. In the second rotatable container, the bulk material is sprayed with a coating material to obtain a bulk material coated with the predetermined stational coating weight gain. A transition phase is provided between the two spray periods during which a load of coated bulk material from the first container is transferred at a transfer flow rate to the second container while a new load of bulk material is fed to the first container at the same flow rate as the transfer flow rate.

A reactor for coating a device is provided. The reactor comprises a hollow body and a port. The hollow body is for supporting the device. The port is in fluid communication with the hollow body for exchanging a coating fluid. In use, the device is moveable within the hollow body from a stacked orientation to an unstacked orientation. Processes for coating devices and systems thereof are also provided.

Coating apparatus (20) includes a pair of juxtaposed bodies (22, 24, 112, 114, 112a, 114a, 138, 140) defining a nip region (30, 126, 126a, 150) therebetween, with each presenting a periphery (26, 28, 116, 118, 116a, 118a, 144, 146) and being rotatable in opposite directions, respectively. The peripheries (26, 28, 116, 118, 116a, 118a, 144, 146) of the bodies (22, 24, 112, 114, 112a, 114a, 138, 140) are provided with a series of indentations (32, 120, 120a, 148). Liquid coating material is directed onto the bodies (22, 24, 112, 114, 112a, 114a, 138, 140) through an outlet (100, 110, 158) during rotation of the bodies (22, 24, 112, 114, 112a, 114a, 138, 140). This generates an adjustable spray or fog flow pattern (108) for effective coating of a substrate.

Coating apparatus (20) includes a pair of juxtaposed, cylindrical bodies (22, 24) defining a nip region (30) therebetween, with each presenting a periphery (26, 28) and being rotatable in opposite directions, respectively. The peripheries (26, 28) of the bodies (22, 24) are provided with a series of laterally extending notches (32), optionally oriented to provide chevron patterns (68) with apices (32a) and diverging legs (70a, 70b); the patterns (68) are positioned so that the apices (32a) first pass through the nip region (30), with the legs (70a, 70b) in trailing relationship. Liquid coating material is directed onto the bodies (22, 24) through an outlet (100, 110) during rotation of the bodies (22, 24). This generates an adjustable spray or fog flow pattern (108) from the apparatus (20) for effective coating of a substrate.

When a slurry 41 obtained by dispersing a rare-earth-compound powder in a solvent is applied to sintered magnet bodies 1, and dried to remove the solvent in the slurry and cause the surfaces of the sintered magnet bodies to be coated with the powder, and the sintered magnet bodies coated with the powder are heat treated to cause the rare-earth element to be absorbed by the sintered magnet bodies, the sintered magnet bodies having had the slurry applied thereto are dried by being irradiated with near infrared radiation having a wavelength of 0.8-5 m, to remove the solvent in the slurry, and cause the surfaces of the sintered magnet bodies to be coated with the powder. As a result, the rare-earth-compound powder can be uniformly and efficiently applied to the surfaces of the sintered magnet bodies.

Transfer rings for use in coating substrates and methods of utilizing same are disclosed. The transfer rings disclosed herein are useful in efficiently moving a plurality of substrates between different process chambers. For instance, the transfer rings are designed to collectively move a plurality of stents between coating and sintering chambers.
