ABSTRACT:
A tray for supporting particulate material in an apparatus for processing. The tray includes an upper plate which has pluralities of associated groupings of first apertures formed therein. The tray also includes a lower plate which has a plurality of second apertures formed therein. Each of said second apertures corresponds with, and generally underlies, one of the associated groupings of first apertures formed in the upper plate. Further, the tray also includes a plurality of staybolts which extend between the upper and lower plates. Each staybolt has a first end which circumscribes an associated grouping of first apertures and defines a shoulder in engagement with a lower surface of the upper plate. Each staybolt also has a second end received through one of the second apertures. Each staybolt also has a wall defining a conduit passing therethrough from the first to the second end thereof. The conduit serves to direct fluid having passed through a corresponding second aperture, through the corresponding associated grouping of first apertures. Spacing and positioning of first apertures in one associated grouping relative to an adjacent grouping of first apertures is such that distribution of all of the first apertures is generally uniform throughout the upper plate.
