Abstract

La présente invention concerne un appareil permettant de sécher ou de conditionner des solides en vrac, qui comprend un boîtier comprenant une entrée pour recevoir les solides en vrac, et une sortie pour décharger les solides en vrac, une pluralité d'ensembles plaques de transfert de chaleur espacés disposés dans le boîtier entre l'entrée et la sortie pour le passage des solides en vrac qui circulent à partir de l'entrée, à travers des espaces entre les plaques de transfert de chaleur, et un système de distribution de gaz de balayage pour la circulation d'un gaz de balayage dans une première direction dans la direction de circulation des solides en vrac. Le système de distribution de gaz de balayage comprend au moins une vanne pour inverser la circulation du gaz de balayage depuis la première direction vers une seconde direction, opposée à la première direction.
