AE 7220 A B S T R A C T The invention relates to a process for the drying and granulation of aspartame through the thermal treatment of a wet mass of aspartame crystals using a hot carrier gas, characterised in that a wet mass of aspartame crystals is supplied, in a continuous process, to a high-speed paddle dryer fitted with a jacket heated to a temperature of 80- 190°C and with paddles, mounted on a central shaft with a controllable speed of rotation, at an adjustable distance from and angle to the jacket, which are positioned so that the required particle size of the granules is realized, the speed of rotation being chosen so that the Froude number is higher than 1, and the supplied product is treated in the paddle dryer for 15-600 seconds, with the simultaneous presence of a carrier gas having an inlet temperature of 100-200°C, and the granular product obtained is discharged from the paddle dryer and, if necessary, dried further - in a manner known per se - in one or more drying steps in other drying equipment. With the use of high-speed paddle dryer aspartame with good microbiological properties is very easily obtained.
