Abstract
L'invention décrit un procédé de séchage de matières poreuses contenant de l'humidité dans un réacteur à lit fluidisé. On règle la teneur en humidité des produits sortant par le bas du secheur et entraînés de ce sécheur en introduisant des gaz chauds dans la région de l'espace libre au-dessus du lit fluidisé. On peut utiliser une ou plusieurs tuyères à grande longueur, comportant des orifices à un niveau supérieur à celui du lit fluidisé dans l'espace libre supérieur, pour admettre des gaz chauds directement dans cette région de l'espace libre, en provenance de la boîte à vent du réacteur, sans traverser le lit fluidisé, où l'on peut utiliser un conduit à soupape traversant le dôme réfractaire ou le distributeur de gaz, pour régler l'écoulement de gaz entre la boîte à vent et l'espace libre supérieur. Le procédé peut notamment s'appliquer à des roches phosphatées, à du charbon, à des lignites, à de la matière protéique synthétisée par des monocellulaires et à des polymères.
