Abstract

On peut réguler la teneur en humidité d'un matériau, tel que des pastilles thermoplastiques (80) dans une trémie (30), en amenant de l'air déshumidifié provenant d'un lit de déshydratant (90) jusqu'à la trémie (30) et en faisant ensuite retourner l'air de la trémie (30) au lit de déshydratant. Un capteur de point de rosée (10) dans le trajet de retour de l'air détermine la teneur en humidité du matériau (80) dans la trémie (30) et, lorsque le point de rosée tombe à un niveau préétabli, une chicane (134) amène le flux d'air de retour à contourner le lit de déshydratant (90) et à retourner à la trémie sans déshumidification. Deux lits de déshydratants sont prévus, l'un est alimenté en continu alors que dans l'autre, le déshydratant est régénéré.
