Abstract

La invención se relaciona con un método para secar sales con un contenido de agua para cristalización en aparatos convectivos que adicionalmente se pueden calentar indirectamente. La invención se caracteriza principalmente porque el proceso de secado se lleva a cabo con un contenido de humedad del gas de secado por encima de un nivel determinado. El gas que rodea las partículas de sal durante el proceso de secado por lo tanto tiene una humedad específica. De esta forma, se influye positivamente la velocidad de secado.
