Device and method for cooling and inserting a flow of pulverulent or granular materials in a storage container

摘要

The device has a conveyor line (9) through which the mass flow is guided and is placed in contact with a cryogenic cooling medium at a nozzle (8). The nozzle opens out in a storage container with a nozzle opening. The nozzle is equipped with a mixer chamber, in which the conveyor line is led in with an outlet section. The cooling medium inlet with an outlet section is arranged in a peak angle to the longitudinal axis of the inlet line in inclined manner such that a cooling medium flow is discharged in the direction of the nozzle opening from the cooling medium inlet. An independent claim is also included for a method for cooling a powder-shaped material.
