Inventors include Herrmann, Thomas; Chatterjee, Michael; Seifert, Alexander; Jafeld, Marco; and Fellmann, Stefan.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: A method for the preparation of a dried powder in a fluidized bed dryer is disclosed. The method is characterized by periodically carrying out a level decrease in which the height of the fluidized bed within the fluidized bed dryer is reduced to a basic height which is from 30% to less than 95%, preferably from 50% to 75% of the setpoint height. It has been surprisingly found that by periodically carrying out the level decrease, plugging and a reduction of heat transfer over time may be mitigated or even avoided.
