The invention relates to a method and a device for producing and treating plastic pellets. According to said method, a melt of the plastic material is granulated to give pellets, the pellets are cooled in a cooling fluid, the pellets are separated from the cooling fluid and the pellets are crystallized. The device according to the invention is characterized by comprising a control unit which monitors the crystallization step and controls the method in such a manner that, in case of a disturbance of crystallization, the pellets are supplied to an intermediate storage alter separation of the pellets from the cooling fluid and, as soon as the disturbance is removed, the pellets temporarily stored in the intermediate storage are supplied to crystallization and are crystallized.

The invention relates to a method and a device for producing and treating plastic pellets. According to said method, a melt of the plastic material is granulated to give pellets, the pellets are cooled in a cooling fluid, the pellets are separated from the cooling fluid and the pellets are crystallized. The device according to the invention is characterized by comprising a control unit which monitors the crystallization step and controls the method in such a manner that in case of a disturbance of crystallization the pellets are supplied to an intermediate storage after separation of the pellets from the cooling fluid and as soon as the disturbance is removed, the pellets temporarily stored in the intermediate storage are supplied to crystallization and are crystallized.

The invention relates to a method for granulating and crystallizing thermoplastic polymers, the granules being contained in a liquid after granulation of a polymer melt and the granules being nucleated in the liquid once the pressure of the liquid is increased and the temperature of the liquid is increased, and the granules being crystallized in the liquid once the pressure of the liquid is again increased and the temperature of the liquid is again increased. According to the invention, the granules are removed from the liquid once the pressure and the temperature of the liquid containing the granules have been reduced.

Device for cooling and granulating molten thermoplastic strands emerging

Device to collect and convey plastic strands, issuing from nozzles, on a discharge plate, over which cooling water flows, with a device to indicate the undisturbed passage of the plastic strands over the discharge plate or their accumulation on the discharge plate. At least one temperature-dependent electric resistor, which triggers a signal by way of a threshold value switch when the specified temperature is exceeded, is attached to a cooling water-free zone on the underside of the discharge plate in the region of impact of the plastic strands.
