Device for producing granulates by melt crystallization process, comprises nozzle pre-chamber for receiving melt, nozzles for production of melt drop, tube for cooling the drops and heating means for preventing undercooling of the nozzles
The device for the production of granulates by a melt crystallization process, comprises a nozzle pre-chamber (1) for receiving a melt, nozzles (5) for the production of melt drops (8), a tube (11) for cooling the drops, heating means (13, 14) for preventing undercooling of the nozzles, means for heating the melt in the nozzle pre-chamber, means for heating the melt present in the nozzle pre-chamber, means for production of a positive pressure in the nozzle pre-chamber, and means for production an oscillation of the melt present in the nozzle pre-chamber. The device for the production of granulates by a melt crystallization process, comprises a nozzle pre-chamber (1) for receiving a melt, nozzles (5) for the production of melt drops (8), a tube (11) for cooling the drops, heating means (13, 14) for preventing undercooling of the nozzles, means for heating the melt in the nozzle pre-chamber, means for heating the melt present in the nozzle pre-chamber, means for production of a positive pressure in the nozzle pre-chamber, and means for production an oscillation of the melt present in the nozzle pre-chamber. The nozzles are arranged in nozzle channels (12), which form an opened withdrawal chamber for the cooling tube downstream of outlets (6) of the nozzles. The heating means has an electrical heating element and a heat transfer liquid, which flows around the nozzle. An independent claim is included for procedure for the production of granulates by a melt crystallization process.
