ABSTRACT:
An improved fluidized bed discharge bin comprising a removable closure covering an opening in the bottom of the bin. The closure is of an inverted pyramidal shape having a square base and an offset nadir. A discharge opening is positioned adjacent to the nadir on the side wall toward which the nadir is offset. An air-permeable member overlies the interior of the closure and is retentively secured between the bin opening and the closure. Positioned at the approximate midsection of each wall is a spacer which prevents the air-permeable member from being compressed in complete surface-to-surface contact with the interior surfaces of the closure. Aeration is introduced into the enclosure through an air inlet correspondingly positioned adjacent to the spacer on one wall of the enclosure. The aeration is readily admitted into the space between the air-permeable material and the interior walls of the closure and allowed to permeate into the bin to fluidize the contents contained in the bin and permit their discharge.
