A PROCESS FOR DRYING GRANULES AND AN ARRANGEMENT FOR CARRYING OUT THIS PROCESS

摘要

The invention relates to process for the production of granules, more particularly surfactant-containing granules, from a moist starting material in an air-flow dryer (1), the granules dried in the dryer (1) being discharged onto a conveyor (3) by a discharge unit (2) sloping away from the dryer (1). In order to provide a simple and inexpensive process in which overgranulation is avoided, it is proposed that the residence time of the starting material in the dryer (1) be controlled through the speed of the conveyor (3). The invention also relates to an arrangement for carrying out the process.
