Abstract: PROBLEM TO BE SOLVED: To obtain two or more fraction having different particle distributions somewhat continuously. SOLUTION: Particulate matter is produced by a continuous fluidized bed spray granulation. In this case, the particulate matter is discharged by a discharge device having classifying effect by an area ratio of time integral of a discharge surface 'f' to floor area F of a fluidized bed causing periodic vibration. By decreasing the area ratio f/F, the vibration is controlled, and by further decreasing it, a change of a amplitude is increased. Fractions of different particle size distributions are obtained by fractionally removing particulate matter during one period. The area ratio f/F is 5 0/00-0.1 0/00.

Abstract: Reducing or preventing foaming in chemical and physical transformation processes in liquid media comprises carrying out the transformation in a buoyancy-free jet reactor with no baffles, which has a tapered lower part and is fitted with a gas injector in a position which facilitates circulation without buoyancy. The reactor contents are thoroughly mixed by gas injection. Also claimed is an apparatus for the above process, with a pipe connection for taking off a high-solids suspension and an inlet tube for a liquid medium above the gas injector, the outlet of this tube being located in the cloud of bubbles formed when the apparatus is working.

Abstract: A fluidized-bed reactor has a chamber (K1) supplied with a continuously sprayed liquid or slurry feed (8.1), a perforate floor for distribution of a fluidizing gas (11.1), an exhaust gas outlet (15.1), and a submerged solids-outlet duct allowing solids to be discharged from a point near the bottom of the bed, to form a moving seal plug of discharging material in the duct, in similar fashion to a siphon An Independent claim is included for: continuous production of coated granules by taking the base granules prepared in a first fluidized reactor chamber as the feed to a second fluidized bed, where a coating material is sprayed on to the granules.

Abstract: The invention relates to an improved process for producing sodium perborate monohydrate by dehydration of sodium perborate tetrahydrate in a fluidised bed by heated air. According to the invention, contact surfaces are arranged within the fluidised bed, the total area of which contact surfaces constitutes 1 - 500 times the area of the gas distribution plate of the fluidised bed. The contact surfaces are expediently designed as heat exchangers, the surface temperature of which is adjusted to 90 to 110@C. The process leads to a sodium perborate monohydrate having particularly high resistance to abrasion; at the same time the energy requirement is lower than in known processes.
