Material dewatering apparatus
First Claim
1. A pneumatic de-watering apparatus or wet product comprising a cyclone chamber connected to a fan with blades, each blade causing individual flow vortices to be formed downstream of the fan which in turn combine to form cyclonic flow within the cyclone chamber characterized in that the cyclone chamber comprises at least a vortex flow forming section having vortex flow forming means to cause reformation of vortex flow within the cyclone chamber on dissipation of the vortex flow along the cyclone chamber remote from the fan.

Abstract
The invention provides a pneumatic dewatering apparatus (1) for wet product. The apparatus (1) comprises essentially a cyclone chamber (2) connected to a centrifugal fan (3). Various vortex flow forming stations (6), each followed by a vortex shedding station (7), are mounted within the cyclone chamber (2). Tight centripetal vortices are formed and are then shed such that water is delivered out the cyclone chamber (2) into a sump (42).

53. A pneumatic method of dewatering wet product comprising:
-
introducing the wet product into a cyclone chamber; delivering air into the chamber; successively forming and shedding vortices within the chamber to violently treat the product to cause the relevant constituents to atomize, expand, boil, chill, shear, gasify, disassociate and cavitate.
