2107666 9217273 PCTABS00016 A bed plate (13) for a fluidized bed apparatus is made from a plate (23) from sheet metal and comprises openings (22) for fluidizing air or gas of the so-called "gill type". In order to reduce or prevent fall-through of product, at least one of the edge portions (24, 34) defining the opening (22) has been deformed so as to increase the extension thereof along the plane of the bed plate, and so as to thereby reduce or eliminate the orthographic projection on said plane of the opening (22). Such deformation may comprise compression and/or stretching. The edge portion or portions (24, 34) are preferably deformed to such an extent that a partial overlap is obtained.
Base de lit (13) pour un dispositif à lit fluidisé fabriquée à partir d'une plaque (23) de tôle métallique et comprenant des ouvertures (22) pour l'air ou pour le gaz de fluidisation, du type << à ailettes >>. Pour diminuer ou empêcher la chute du produit, au moins une des parties du bord (24, 34) délimitant l'ouverture (22) a été déformée de manière à la prolonger dans le plan de la base du lit et de manière à réduire ou à éliminer la projection orthographique de l'ouverture (22) sur ce plan de l'ouverture. Une telle déformation peut prendre la forme d'une compression et/ou d'un étirage. La ou les parties des bords (24, 34) sont de préférence déformées à un point tel qu'il y a chevauchement partiel.
