Title:
【発明の名称】流動床装置用ベッドプレートおよびその製造方法
Document Type and Number:
Japanese Patent JPH06507116
Kind Code:
A
Abstract:
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.
