| abstract |
The invention relates to a dripping device for producing granules (9) from a low-viscosity plastic melt, comprising a molding nozzle (3) with boreholes, in which the plastic melt can be supplied with harmonious pressure vibration such that the plastic melt exiting there from the boreholes forms granule drops (8), a pressurized container (1) in which excess pressure prevails over ambient pressure, with a drop section (f) in a gas space (4) and a cooling section (k) comprising a coolant (5), into which the granule drops are immersed, an output device (10), and a separator (11), wherein the excess pressure in the pressurized container can be set at least as high as the steam pressure of the volatile substances present in the plastic melt, the length of the drop section (f) in the gas space can be set, a collecting device (6) is provided after the drop section (f), and at least one circulation device (7) is provided for the coolant, wherein turbulence in the coolant can be generated by the circulation device. The invention also relates to a corresponding dripping method. |
