Abstract

L'invention concerne un séchoir à air chaud pourvu d'un récipient (16) en forme de boîte généralement cylindrique chargé de substances à sécher et présentant une certaine perméabilité, monté de façon amovible dans le corps principal (13) d'un four. De l'air chauffé par le brûleur (5) d'un dispositif chauffant (2) est injecté sous forme d'air chaud (36) dans le partie principale (51) du tube d'un conduit (46) à l'aide d'organes (43) d'alimentation d'air chaud, l'air chaud étant commuté pour n'être alimenté que par un conduit supérieur (52) ou un conduit inférieur (53) en peu de temps, un module (57) de commutation étant situé à l'intérieur du conduit (46). L'air est injecté dans des buses (31 et 32) à injection d'air chaud situées sur les côtés supérieur et inférieur du récipient (16) par le conduit supérieur (52) et le conduit inférieur (53). L'air chaud (36) est injecté, sous forme de flux en spirale, sur les surfaces opposées des buses (31 et 32) à injection d'air chaud à travers des orifices (34) d'injection d'air chaud ouverts dans la même direction et sur approximativement la même circonférence, l'air chaud (36) étant ainsi commuté pour être injecté à travers les conduits supérieur et inférieur en peu de temps, et les substances à sécher sont déplacées verticalement de façon à augmenter l'efficacité de contact de l'air chaud afin d'augmenter l'efficacité de séchage.
