Abstract:
1. A drop pelletizing device for producing pellets from a low-viscosity plastic melt, wherein the drop pelletizing device comprises: a. a die plate with holes, in which a plastic melt can be subjected to a harmonic pressure oscillation such that the plastic melt emerging from the holes forms individual pellet droplets; b. a pressure vessel, in which prevails an overpressure above an ambient pressure, wherein the pressure vessel comprises: c. a discharge device adapted to discharge the individual pellet droplets from the pressure vessel and to reduce the overpressure; d. a separator adapted to separate the individual pellet droplets from the coolant; and e. at least one circulating device adapted to agitate the coolant to separate and unclump the individual pellet droplets in the coolant and produce turbulence within the coolant.
