Technologies are described for a method of making an encapsulated reactant having a desired shape or size. The method comprises providing solid reactant particles and an encapsulating material. The encapsulating material is heated above its solidification temperature to form a molten, semi-solid, or liquid encapsulating material. The solid reactant particles are added to the molten, semi-solid, or liquid encapsulating material and mixed to disperse the solid reactant particles in the encapsulating material and form a mixture. The mixture may be extruded or formed into the desired shape or size of the encapsulated reactant, or the mixture may be solidified and extruded, granulated, shredded, ground, or pressed into the desired shape or size.

A process of granulation of a urea melt, comprising: adding a first additive containing carboxymethyl starch to one or more first stage(s) of the granulation process, to form a carcarboxymethyl starch containing inner layer of urea granules, and adding a second additive containing calcium lignosulfonate to one or more second stage(s) of the granulation process, downstream said first stages, to form granules with a coating containing calcium lignosulfonate.

A drum coater device (10) for coating tablets, comprising a mixing drum (18) which can be rotated about an axis of rotation (20) and which has an interior (24) for arranging a tablet batch to be coated, further comprising a spraying device for introducing a coating material into the interior, wherein the mixing drum has a hollow-cylindrical, perforated wall which delimits at least part of the interior of the mixing drum, wherein mixing elements for mixing the tablets of a tablet batch are arranged on the inner side, which faces the interior, of the wall, wherein pairs (36) of mixing elements (34a, 34b) form legs which are oriented with respect to one another in a V shape, wherein the distance between the legs of a pair widens from a central annular region, as seen along the axis of rotation, of the wall in the direction of lateral annular regions adjacent to the central annular region.

This coating device 1 comprises a dispersing/mixing part 2, a conveying part 3, and a collecting part 4. A raw material powder and a coating solution are supplied to the dispersing/mixing part 4 as a slurry. In the dispersing/mixing part 2, the slurry (mixture) in which the raw powder and the coating solution have been mixed is dispersed by means of an air flow of a high-pressure fluid into a powder, a film of the coating solution having adhered to the surface of the powder. The powder is introduced from the dispersing/mixing part 2 to the conveying part 3t and is conveyed with the conveying part 3 oriented toward the collecting part 4. While the powder is being conveyed, the coating solution that has adhered to the particle surfaces dries, whereby a powder in which the particle surfaces ares coated with a precursor is produced. A powder flow introduced into the collecting part 4 passes through a bag filter 54. This causes the powder to be captured by the bag filter 54.

A reactor for coating particles includes a stationary vacuum chamber to hold a bed of particles to be coated, a vacuum port in an upper portion of the chamber, a chemical delivery system configured to inject a reactant or precursor gas into a lower portion of the chamber, a paddle assembly, and a motor to rotate a drive shaft of the paddle assembly. The lower portion of the chamber forms a half-cylinder. The paddle assembly includes a rotatable drive shaft extending through the chamber along the axial axis of the half cylinder, and a plurality of paddles extending radially from the drive shaft such that rotation of the drive shaft by the motor orbits the plurality of paddles about the drive shaft.

A process for coating carrier particles with inhalable drug guest particles, the process including providing an apparatus including a processing vessel having solid walls defining a chamber for receiving the particles and adding the particles to the chamber. Next, the cylindrical processing vessel is rotated about an axis to impart a centrifugal force of between 10 and 2100 g on the particles. Further a process coats carrier particles with guest particles, wherein the carrier particles include a material or a drug and wherein the guest particles include a solubility/dissolution controlling agent.

Disclosed is a method of coating fertilizer particles with a coating, the method comprising providing fertilizer particles in a coating unit, one or more steps of applying a coating layer by applying one or more coating components to the fertilizer particles in the coating unit, and at least, partially curing or hardening the coating layer, wherein said curing or hardening involves a chemical reaction of said one or more coating components, discharging the coated fertilizer particles from the coating unit, optionally after a final cure or hardening step, wherein the coating unit comprises a stationary frame and at least two movable elements.

Carriers are disclosed for supporting a plurality of agricultural cores on a plurality of core supports for coating by a flexible film. The plurality of core supports may include a pedestal for supporting a respective agricultural core and a core periphery region having a plurality of bridge elements which couple the pedestal to the connecting structure between the plurality of core supports. The carriers may include a vacuum system that independently communicates a partial vacuum to an aperture in each respective pedestal and a plurality of apertures in the core periphery region of a respective core support between the bridge elements.

A modular coating drum for use in a production or laboratory coater for coating a material with a solution or a suspension. The modular coating drum includes a perforated sidewall between two removable drum end plates, each of the drum end plates attached to an end of the perforated sidewall by a releasable fastener. The drum end plates can be used with two different sizes of sidewalls.
