The disclosure encompasses systems and methods for performing high temperature and high humidity curing of tablets using air flow delivered from a recirculating air handler to a pan coater of a tablet coating device. The recirculating air handler may be integrated into a preexisting tablet coating device so that the air flow may be delivered by the preexisting air handler or by the recirculating air handler as desired.

The present invention is directed to a process for coating a substrate in a rotating drum, wherein a pocket is created in a substrate bed into which pocket coating materials are delivered. Also provided is a controlled release product produced according to this process, and an apparatus for carrying out the process.

A plasma spray system including a turntable subsystem operable to position a multiple of work pieces on a respective multiple of workpiece mounts; a plasma spray subsystem operable to plasma spray the multiple of work pieces on said turntable subsystem; and an overspray wash subsystem operable to wash the multiple of work pieces on said turntable subsystem subsequent to plasma spray of the multiple of work pieces.

An apparatus including an air blower; a rotary airlock; a receptacle having an inner chamber supplied with a plurality of colorant particles; a water supply; and a mixing chamber. The air blower blows air into a bottom section of the rotary airlock, and the rotary airlock receives colorant particles from an output of the receptacle. A rotor shaft of the rotary airlock rotates to cause colorant particles to be transported to the bottom section of the rotary airlock. Air blown into the bottom section of the rotary airlock mixes with colorant particles transported into the bottom section of the rotary airlock to form an air and colorant particles mixture, which is blown out of a first output of the rotary airlock and combined with water to form a water, air, and colorant particles mixture, which is mixed with material in a mixing chamber. The material may be natural mulch.

A plasma spray system including a turntable subsystem operable to position a multiple of work pieces on a respective multiple of workpiece mounts; a plasma spray subsystem operable to plasma spray the multiple of work pieces on said turntable subsystem; and an overspray wash subsystem operable to wash the multiple of work pieces on said turntable subsystem subsequent to plasma spray of the multiple of work pieces.

A wet powder manufacturing apparatus includes a housing being arranged such that a central axis CL of the cylindrical inner surface extends in a substantially horizontal direction, a plurality of stirring blades provided rotatably about the central axis CL, a rotary plate configured to rotate the stirring blades about the central axis CL such that the wet powder accumulated at the bottom of the cylindrical inner surface is scooped by the stirring blades and then dropped, a driving device configured to impart a rotary force to the rotary plate, a liquid diffusing device configured to diffuse liquid into the drum inner space so as to wet the powder, and a controller configured to control operations of the driving device and the liquid diffusing device. The controller includes control for vibrating the stirring blades.

In a method of coating a particulate material, a particulate material is fed into a mixing chamber. The particulate material is agitated within the mixing chamber and conveyed to a mixing chamber outlet. A coating is directed into the mixing chamber and the flow of the coating is controlled based on the volumetric flow rate of the particulate material into the mixing chamber. The coating includes at least one compound selected from herbicides, insecticides, nutrients, wetting agents, surfactants, fungicides, biologicals, inoculants, and mixtures thereof.

A continuous dosage form coating apparatus uses vibrational impulses to maintain a dosage forms in a fluid state to expose them to a coating material atomized by spraying.

A cleaning arrangement (200) for a coating apparatus (100). The coating apparatus has a base (123) for carrying loose material. The base is rotatable to coat the loose material. The cleaning arrangement includes a base-scraping arrangement (127) and further includes a mounting arrangement (131) by which the base-scraping arrangement is mounted to be reversibly lowered, from a coating position, to a scraping position at which the base-scraping arrangement is positioned to scrape buildup from the base.

A method and a system for coating products are provided. The method includes the steps of applying a coating liquid to a product and removing excess coating liquid from the product. It is desirable to provide a method and system for efficiently and reliably coating delicate or easily deformable products, such as products molded from a pulp fiber slurry. The method includes fixing the product to a receiving portion of a product carrier that is configured in the same shape as the product, such that an exterior surface of the product abuts the interior concave surface of the receiving portion of the device. A coating liquid is applied to the product in the product carrier. The product carrier is affixed to a centrifuging device and the coating liquid is dispersed over the surface of the product using centripetal force.
