Abstract

An improved endless conveyer belt is provided which can carry minute particles of conveyed product such as are found in packed bed applications, without limiting the ability of the conveyor belt to articulate into a spiraling conveyor stack. The perforations in the foraminous bottom member of the conveyor belt can be dimensioned according to the size of conveyed products. The number and placement of the perforations can be chosen to alter gas flow characteristics of the belt.
