Abstract
The invention concerns an apparatus for the removal of moisture from particulized, solid food products, comprising; a housing (9); a perforated plate (2), creating two chambers (3, 4) in the housing (1), gas-inlets (5, 6), present below the perforated plate (2); an outlet (8) in the perforated plate (2), provided with a removable plug (9); heating means (15, 18) for the gases. The invention further concerns a process for the removal of moisture from solid, small particles, by subjecting these particles, while in an annular, fluidized bed to a heat treatment for a specific time.

Apparatus for the removal of a fluid component from particulized solid materials comprising:
- a housing (1)
- a perforated plate (2) separating the housing (1) into two chambers, a first chamber (3) and a second chamber (4), the first chamber (3) being a gas introduction chamber and the second chamber (4) being a reaction/drying chamber, whereby:
- the first chamber (3) is provided with two separated gas inlets which are a first inlet (5) and a second inlet (6)
- the first gas inlet (5) being present in a bottom (7) of the first chamber and providing an axial direction to the gas and
- the second gas inlet (6) being present below the plate (2) and providing a tangential direction component to the gas
- the perforated plate (2) is provided with an outlet opening (8) which is provided with a removable plug (9) for the opening and closing of the outlet opening (8)
- mean (10) for feeding the solid particulized material into the second chamber (4)
- a gas outlet system (17) for the removal of the gases from the second chamber
- heating means (15, 18) for the heating of the gases introduced via the first gas inlet (5) and the second gas inlet (6).
Process for the removal of a fluid component from particulized solid material in a reactor by treatment gases having two components, wherein the solid particulized material is fluidized by a preheated gas providing to the solid particles an axial velocity component and a preheated gas providing to the solid particles a tangential velocity component, which is introduced in the reactor below a perforated plate that forms a barrier between an introduction chamber for the treatment gases and a reaction chamber in such a way that during the heat treatment the solid particles form a fluidized, annular bed of particles, at a temperature and for a time sufficient to remove the fluid component without overburning of the solid particulized material, whereupon the treated solid particulized material is separated from the reactor as end product, while thereafter fresh solid particulized material, from which the fluid component still must be removed, is introduced in the reactor.
