METHOD FOR COATING PARTICLES
Methods are provided for coating particles characterised by the addition of a powdered excipient, typically during coating. Typically, the coating method comprises Wurster fluidized bed coating. The method provides for coating particles in a coater comprising a coating processing chamber, wherein the particles comprise an active pharmaceutical ingredient. The coated particles are preferably for use in a method of administering an active pharmaceutical ingredient or for use in a method of treating or preventing a disease or condition. The invention further provides a pharmaceutical composition comprising coated particles obtainable by the method of the invention, preferably as part of a liquid formulation for oral administration.
FLUIDIZED BED SYSTEM
A fluidized bed system is a single unitary modular system that packages a circulation fan, a fluidized bed, and a dust collection system within a same structure. The structure is formed to include internal ducts to provide fluid communication between the circulation fan, the fluidized bed, and the dust collection system. The fan provides a flow of air via a pressure duct to the fluidized bed. Particulate is separated from particles included on the fluidized bed by the flow of air being uniformly distributed to the fluidized bed. Particulate separated in a disengagement area and suspended in the flow of air is conducted through a particulate clearance space surrounding the dust collection system. The particulate is captured by the dust collection system and conveyed to a location external to the system.

METHOD AND DEVICE FOR THERMAL ROUNDING OR SPHERONISATION OF POWDERED PLASTIC PARTICLES
A method for shaping a starting material of powdered plastic particles includes the following steps: a) providing powdered plastic particles as a starting material; b) heating the plastic particles in a first treatment space to a first temperature below the melting point of the plastic, the first temperature being determined such that the plastic particles do not yet stick to one another; c) transferring a directed current of the plastic particles thus heated into a second treatment space; d) heating the plastic particles in the second treatment space to a second temperature above the melting point of the plastic; and e) cooling the plastic particles to a temperature below the first temperature.

Device for drying and recovering carbon nanotube product and method for manufacturing carbon nanotube using same
The present invention relates to a device for drying and collecting a product such as a carbon nanotube pellet or aggregate, which can accelerate solvent evaporation by inserting and dispersing high temperature gas into a drying column as well as by a heat source inside and outside of the column, and can quickly remove the evaporated solvent. Further, the device can be used for drying and collecting processes while minimizing product breakage by regulating the gas flow rate and controlling flow of the product in the column. Thus, the device can be effectively applied to mass production of a carbon nanotube pellet product.
