ABSTRACT:
A method and apparatus for drying particulate material in which the drying and discharge of the particulate material may be superimposed in such a way as to permit continuous drying of particulate material even when the supply is not continuous. The quantity of heat supplied to the particulate material is controlled as a function of signals (i; hi) from temperature sensors mounted in the particulate material, which signals represent temperatures detected locally, and also as a function of a preselectable residence time (Tv) of the particulate material at a temperature within a preselectable target temperature range (min,max) and a preselectable throughput of dried particulate material such that the particulate material discharged has a temperature within the target temperature range (min,max) at least during the residence time (Tv).
