Abstract: The invention relates to a process and an apparatus for pelleting materials capable of forming drops, in which the materials to be pelleted are added dropwise into a coolant liquid bath (5), preferably a liquified gas, hardened and are kept separate on a vibratory conveyor unit (7) with supply of vibratory energy and are completely frozen solid, exploiting the temperature of the cold gas.

Abstract: The invention relates to a process and to a device for pellet-freezing pourable and flowable materials in a low-boiling liquefied gas (11) which is located in the interior of an insulated housing (1) having an aperture for introducing the material to be frozen. To generate a cascade-like flow (12), in which small drops can be frozen individually, coupled with a small surface area requirement of the immersion bath, there is, according to the invention, in the interior of the housing (1), a reaction tube (2) with an agitator (3) which is arranged at the lower end, the charging device (13) for the material to be frozen being arranged above the aperture (18) thereof.
