Abstract

An apparatus for distillation of feedstock, including a distillation chamber with an inlet for receiving feedstock and an outlet for discharging feedstock, and a plate for supporting the feedstock in the distillation chamber. The plate is positioned parallel to a substantially horizontal plane across a portion of the distillation chamber, and defines a plurality of transverse apertures extending transversely across a substantial portion of the width of the plate. A plurality of heating rods is included for insertion into the apertures of the plate to heat the plate. The apparatus also includes a conveyor enclosed within the distillation chamber and extending longitudinally across the distillation chamber, the conveyor having a plurality of paddles attached thereto that, when driven by the conveyor, move proximate and parallel to the plate to agitate feedstock on the plate, and to drive the feedstock from the inlet to the outlet of the distillation chamber.

Claims

1. A method of processing feedstock in a distillation device, the method comprising:

a) introducing feedstock into a distillation chamber so that the feedstock rests on a substantially horizontal plate in the distillation chamber, wherein the plate includes transverse heating apertures extending transversely across the full width of the plate from a first end to a second end;

b) inserting elongate heating rods into the transverse heating apertures in the plate, wherein the elongate heating rods extend across the full width of the plate from the first end to the second end;

c) heating the elongate heating rods, so that the elongate heating rods transfer heat to the plate, which in turn transfers heat to the feedstock;

d) agitating the feedstock by driving paddles through the feedstock to move the feedstock laterally, as well as forward and vertically upward; and

e) discharging the feedstock from the distillation chamber.

2. The method of claim 1, further comprising:

arranging the paddles in rows, the lateral position of the paddles of each row varied from that of the paddles in an adjacent row, to increase the lateral and forward movement of the feedstock as the feedstock is agitated.

3. The method of claim 1, further comprising:

orienting the paddles so that as they pass through the feedstock, they move the feedstock vertically upward so that the feedstock is constantly circulated from a position adjacent the plate to a position removed from the plate.

4. The method of claim 1, further comprising:

mixing gases within the distillation chamber prior to venting the gases from the chamber.

5. The method of claim 1, wherein step a) further comprises:

electrically heating the elongate heating rods.

6. The method of claim 1, wherein the plate comprises a plurality of plate sections.

7. The method of claim 1, further comprising inserting a plurality of thermocouples into the transverse heating apertures of the plate to measure temperature of the plate.
