<p>An air fluidised bed comprises a diffuser sheet (5) of porous sintered polyethylene located between a plenum chamber (4) and a fluidising chamber (6) containing particulate material. An air permeable cover sheet (7) overlies the fluidising chamber. Air introduced into the plenum chamber passes through the diffuser sheet and fluidises the particulate material.</p> |
