A spray coating machine and process accommodates coating pans of various sizes and simplifies cleaning after particulate material in the pan is coated. A selected pan is supported on a trolley carried by a wheeled cart. After the cart is positioned adjacent the coating machine, the trolley and pan are extended into the machine, and then the pan lifted for support by a rotatable drive shaft and castors. The trolley is then removed from the machine, and the door is closed so that the coating process can commence. When coating is complete, the door is opened, and the trolley extended into the machine under the pan and raised for removal of the castors. Then, the trolley and pan are withdrawn from the machine. The trolley does not need cleaning after spraying, since the trolley is outside the machine during spraying of the coating solution.

A system for heating, coating, cooling and screening a granular substrate is provided. The system, such as an apparatus for continuous coating granular particles, includes a preheater apparatus for heating granular particles, a rotary drum having an inlet horizontally coupled to the preheater for receiving heated granular particles directly from the fluidized bed preheater, a coating apparatus positioned within the drum for applying a coating to the heated granular particles, and a cooling apparatus positioned horizontally in association with the drum for cooling the granular particles subsequent to coating.

An apparatus for coating pharmaceutical particles such as drug dosage forms or pellets is provided which includes a drum assembly mounted for rotation about a cylindrical axis of the drum and which includes an outer drum section and an inner perforated drum section mounted concentrically on an interior of the outer drum section such that an annular chamber is formed between the perforated inner drum section and the outer drum section. Two or more baffle plates are attached between an outer surface of the inner perforated drum and an inner surface of the outer drum which are configured to act as baffles to restrain or regulate the flow of air which define two or more compartments depending on the number of baffle plates. One end of the drum assembly includes an end plate with a central aperture for use in loading pellets into the drum and provide access to coating constituents that are pumped into the drum interior during the coating process. An air distribution plate is attached at the other end of the drum and has air flow passageways and is interfaced with an air introduction plate having air inlet and outlet passageways. As the drum rotates the air flow passageways in the distribution plate alternately come into flow communication with the air inlet and outlet passageways in the air introduction plate thereby providing a flow path of air into the perforate inner drum and out of the drum assembly.

The system, such as an apparatus for continuous coating granular particles, includes a preheater apparatus for heating granular particles, a rotary drum having an inlet horizontally coupled to the preheater for receiving heated granular particles directly from the fluidized bed preheater, a coating apparatus positioned within the drum for applying a coating to the heated granular particles, and a cooling apparatus positioned horizontally in association with the drum for cooling the granular particles subsequent to coating.

In the coating apparatus for granular bodies is disposed a rotatable hollow cylindrical drum in which there is an introduction apparatus for granular bodies and at least one movable separating element therein, with which a cycle zone can be partly separated from a downstream cycle zone and a movement of the at least one separating element that leads to release is achievable. An interior of the drum is divided into at least one cycle zone and a further cycle zone. A spray apparatus is disposed in one cycle zone, and an outlet in a cycle zone arranged downstream. A separating element is movable from a closed position into an open position. A separating element has a clear space above the closed subregion and an opening between one cycle zone and a cycle zone arranged thereafter, through which granular bodies can pass.

A drum coater for applying a surface layer on bulk-like materials includes a rotatably mounted drum for accommodating bulk-like materials, inlet and outlet openings, at least one spray nozzle for applying the surface material, a drying device for a drum interior, at least first and second radially-offset mixing tools in the drum, the first mixing tool protruding into the drum interior. The at least one second mixing tool has at least one mixing surface such that the first mixing tool is at least partially arranged on the drum inner surface and the at least one second mixing tool has at least one opening on the at least one mixing surface. A mixing tool to be used in a drum coater to gently blend and/or homogenize bulk-like materials has a first mixing surface angled relative to a second mixing surface, at least one mixing surface having at least one opening.

Methods and apparatus for electrostatic dispensing fluid onto food products are disclosed. An electrostatic dispense system includes a material supply, a voltage block, and a power supply to electrostatically charge a coating material. The electrostatic dispense system further includes a dispense assembly, a conveyor through or by which a food product is configured to be conveyed, and a support that supports at least one liquid outlet of the dispense assembly. The dispense assembly dispenses the electrostatically charged coating material from the at least one liquid outlet onto the food product. The voltage block provides electrical isolation, and includes a pump that pumps the electrostatically charged coating material to the dispense assembly.

A device for wetting particles, in particular wood particles, with an application agent, at least one conduit transporting a fluid as a fluid stream and an end section which forms an outlet. The fluid can be introduced in the direction of the main flow into a container containing the particles, via the outlet. The particles are in the container in a loosened state and/or can be loosened. The application agent, for spraying by a nozzle device with a speed component directed against the main flow direction, can be introduced into the fluid stream and can be guided to the particles by the fluid stream.

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.

The present invention relates to a coating device for small parts, in particular for lacquering mass produced small parts, like e.g. bolts, small plastic parts and similar, and it relates to a method for this purpose with a movable receiver element for receiving and moving the small parts, and a dispenser device, located at the receiver element for continuous or portioned dispensing the coating material into the receiver element, wherein a radiation emitter device is provided in the receiver element for emitting radiation for drying and/or hardening the coating material.
