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.

An apparatus for producing granules from two-phase mixtures comprising a temperature controlled precrystallizer means for cooling an initial substance enriched with crystal nuclei and wherein the resultant precrystallized melt is fully crystallized on a cooling surface, said apparatus further comprising a droplet former disposed over said cooling surface and including inner and outer telescoping tubes, said tubes having mutually facing surfaces which interengage, said inner tube communicating downstream with said precrystallizer and having a plurality of outlet orifices for conducting the precrystallized melt outwardly therethrough, said outer and inner tubes being arranged for relative rotation, said outer tube having a plurality of discharge orifices which are intermittently alignable with said outlet apertures in response to relative rotation between said tubes for discharging drops of precrystallized mass onto said cooling surface, and means for effecting relative rotation between said inner and outer tubes.
