Abstract: By means of a method for the uniform distribution of a small amount of liquid onto the surface of finely divided solids, characterised in that the said liquid is sprayed by means of one or more ultrasonic jet(s) onto the finely divided solids to be treated before or during, or before and during mixing of the said solids in a mixing apparatus, granules, powder or dusts can be dedusted by the use of very small amounts of liquid. The method according to the invention is also suitable for applying emulsions, solutions, dispersions or melts onto the surface of solid particles. The invention also relates to an apparatus for carrying out the said method, characterised in that one or more ultrasonic jet(s) is or are combined with a mechanical or pneumatic mixer.

Abstract: The lyogel particles are arranged in a packed bed and a dry gas passed through from top to bottom. The gas is passed into the bed from above, at an inlet temperature of 100-200 deg C. The blower stream velocity is between 1 and 40 cm/s. The packed bed has a thickness of 20 to 100 cm and rests on a device acting as an outlet from the packed bed which allows the gas to pass but not the Lyogel particles. The exiting gas is recirculated in a 1st phase, fresh gas being used in a 2nd phase drying.
