ABSTRACT:
An apparatus produces granules from two-phase mixtures wherein an initial substance is enriched with crystal nuclei in a temperature controlled precrystallizer and the resultant precrystallized melt is fully crystallized on a cooling surface. A droplet former is disposed over the cooling surface and includes inner and outer telescoping tubes. The inner tube communicates downstream with the precrystallizer and has a plurality of outlet orifices for conducting the precrystallized melt outwardly therethrough. The outer and inner tubes are arranged for relative rotation. The outer tube has a plurality of discharge orifices which are intermittently alignable with the outlet apertures in response to relative rotation between the tubes for discharging drops of precrystallized mass onto the cooling surface.
