Process and plant for the production of a urea ammonium sulfate granulate. In a first fluidized bed a first spraying liquid is sprayed comprising a urea melt and an aqueous solution of ammonium sulfate, e.g. a (near-) eutectic mixture. The bed temperature is below the crystallization temperature of the sprayed mixture. In a next compartment the granulate is fluidized to form a second fluidized bed. A second spraying liquid comprising a urea melt is sprayed into the second fluidized bed with a bed temperature higher than the bed temperature of the first fluidized bed and lower than the crystallization temperature of the sprayed second spraying liquid.

A process and to an apparatus for production of a granular cannabinoid material essentially soluble in aqueous medium, wherein a matrix liquid composed of a first liquid that dissolves a cannabinoid or composed of a first liquid that dissolves a cannabinoid and a second liquid that forms an emulsion with the first liquid and a cannabinoid dissolved in the first liquid or emulsion is produced. The matrix liquid is dried by convection, and wherein the apparatus has a vessel system having an inlet and a matrix liquid outlet for production of the matrix liquid and a drying apparatus fluidically connected to the matrix liquid outlet of the vessel system.

An apparatus for the production of solid dosage forms is presented, wherein the apparatus comprises a material processing chamber which is operable for manufacturing a product according to a pre-set product formation process path. The apparatus has at least one sensor for continuously monitoring formation of the product in the material processing chamber during the product formation process non-invasively in real time by sensing at least one product functional attribute value and a means for comparing each sensed product functional attribute value with a desirable product functional attribute value for that point on the product formation process path. A controller controls operation of the material processing chamber in response to the sensed product functional attribute value for maintaining the product on the product formation process path.

A method for removing solvent from a solvent containing sweep gas stream obtained from a fertilizer coating process is disclosed. The method can include directly contacting the solvent containing sweep gas stream with an aqueous composition comprising 50% wt/wt to 100% wt/wt of water, condensing at least a portion of the solvent out of the solvent containing sweep gas stream into the aqueous composition to produce a solvent-enriched aqueous composition and a recovered sweep gas stream, and removing the recovered sweep gas stream from the solvent-enriched aqueous composition.
