Method and a drum coater for coating small items, such as tablets, and a coating system comprising such drum coaters
The drum coater comprises a substantially cylindrical drum (11) with a peripheral wall and a substantially horizontal axis of rotation. The method comprises providing a coating zone within the drum, feeding tablets into the drum, spinning the drum containing the tablets at a rotational speed such that a substantially annular bed of tablets is created, providing means for creating a cascade (19) of tablets at least in a part of the coating zone and spraying the tablets in the coating zone.

Device for producing a granulate
A device for granulating coarse material is disclosed herein. Examples of course material include pulverulent solids such as powder, grain, or mixtures thereof. The device includes a rotor, a screen, and an automatic distance adjusting unit. The rotor is configured to rotate/oscillate and press the coarse material through the screen in order to produce a granulate with a smaller granulate unit size compared to the coarse material. The automatic distance adjusting unit is configured to adjust a distance between the rotor and the screen.

Printing head module
A printing head module for a 3-D printing apparatus includes a 3-D print head, an ink-jet print head and a baking module. The 3-D print head includes a melting module and a base-material nozzle to print a plurality of staking layers. The ink-jet print head is connected to the 3-D print head and includes an ink nozzle to dispense ink on each stacking layer. The baking module is disposed between the 3-D print head and the ink-jet print head and includes a fan, a discharge casing and a heating module. The fan includes an air-discharge side facing the base to provide an air flow. The discharge casing is disposed on the air-discharge side. The heating module is disposed between the fan and the discharge casing to heat the air flow and the heated air flow being blown out via the discharge casing for drying the ink layer.
Apparatus for powder coating of particles
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.

Dry powder processing
A method for forming a pelletised evaporite mineral product, the method comprising: pulverising an evaporite mineral feedstock to form a dry powder, mixing the dry powder with a binder in the presence of a liquid to form an intermediate blend; and processing the intermediate blend using a pelletiser to form pellets principally composed of the evaporite mineral.
