Method for producing particulate goods |
摘要 |
In the method for producing a particulate material (58) from an at least partially liquid material (35) containing a solvent and/or dispersant, this material (35) is atomized in a process chamber (21) into droplets which are frozen to particles (131) by contact with a freezing fluid. The particles (131) are then dried by freeze-drying in the or in another process chamber (22) having a filter (18) at the top. For the freeze-drying, cooled process gas is passed upward from below through the process chamber (22) and through the filter (18) in such a way that at least a substantial part of the particles (131) rest against the filter (18) at least for a substantial part of the freeze-drying taking place in the process chamber (22). This makes it possible to dry a batch of particles (131) in a short time.
