19. A method for producing plastic parts, the method comprising:
feeding a first liquid plastics starting component and a second liquid plastics starting component to a mixing chamber of a mixing device;
mixing the first liquid plastics starting component and the second liquid plastics starting component in the mixing chamber to form a plastics mixture;
spiraling a coolant around the mixing device to cool the mixing device;
discharging the plastics mixture through a discharge nozzle; and
drying the mixing device using a drying device that at least partially surrounds the mixing device by introducing compressed air into a drying chamber defined between the mixing device and a separation device via a pipe at least partially extending into the drying chamber;
wherein a dew point temperature of the compressed air is below 5° C.
