Abstract
Method and apparatus for heating and removing moisture from moist or watery material, wherein a watery material is introduced into one end of a rotating cylindrical drum having a section divided into a number of longitudinally extending compartments including a center compartment and circumferential compartments surrounding the center compartment and each accommodating freely disposed packing members. A hot gas is blown axially through the drum while the packing members in the respective compartments are caused to tumble in contact with the watery material to transfer the sensible heat of the hot gas thereto.
Claims10
A method for heating and removing moisture from watery material, comprising:
- introducing a watery material into one end of a rotating drum having a sectional area divided by perforated partitions into a number of longitudinally extending compartments including a center compartment and circumferential compartments each accommodating and retaining loose packing members disposed to tumble freely within a given compartment;
- blowing hot air axially through said rotating drum from said one end;
- and
- discharging dewatered material and exhaust gas from the other end of the rotating drum.
An apparatus for heating and removing moisture from watery material, comprising:
- a rotatably supported drum of cylindrical shape having an inlet and an outlet at opposite ends;
- a plurality of perforated partitions dividing said drum into a number of longitudinally extending compartments for accommodating packing elements including a center compartment and circumferential compartments around said center compartment each compartment retaining packing elements therein, said perforated partitions all allowing passage of the watery material while blocking passage of the packing elements;
- a feeding duct extending to said inlet of said drum for feeding watery material thereto;
- means for introducing a hot gas axially through said drum;
- and
- means for removing exhaust gas from said drum.
