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. An apparatus for distillation of feedstock, comprising:

a substantially enclosed distillation chamber with an inlet for receiving feedstock and an outlet for discharging feedstock;

a plate enclosed within the distillation chamber for supporting the feedstock in the distillation chamber, the plate positioned parallel to a substantially horizontal plane across a portion of the distillation chamber, the plate defining a plurality of transverse apertures extending transversely across a substantial portion of the width of the plate;

a plurality of heating rods for insertion into the apertures of the plate to heat the plate;

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.

2. The apparatus of claim 1, wherein the paddles are arranged in transverse rows, each row containing three or more paddles separated from one another a predetermined distance so that feedstock can pass between the paddles as the paddles move relative to the plate.

3. The apparatus of claim 2, wherein the transverse position of the paddles in adjacent rows varies so that the feedstock is constantly agitated as the rows of paddles move relative to the plate.

4. The apparatus of claim 1, wherein each paddle has a substantially V-shaped cross-section, with a leading edge and two sides that angle outwardly from the leading edge toward the sides of the distillation chamber, and behind the leading edge in a direction opposite the movement of the paddles, so that as the paddles move through the feedstock they separate and move the feedstock in a forward and lateral direction.

5. The apparatus of claim 4, wherein when each paddle is positioned adjacent the plate so that it is agitating the feedstock, and each paddle is positioned at a negative acute angle relative to the conveyor so that as the paddles move through the feedstock, the feedstock is driven upwardly over the top of the paddles.

6. The apparatus of claim 1, wherein the cross-sectional shape of the distillation chamber includes a substantially horizontal bottom, two substantially vertical sidewalls, and a top having pitched sides meeting at a curved peak, so that as gasses are produced by the distillation process the shape of the chamber will encourage mixing of the gasses in the top thereof.

7. The apparatus of claim 1, further comprising:

a plurality of thermocouples for insertion into the apertures of the plate to measure temperature of the plate.

8. The apparatus of claim 1, wherein the plate comprises a plurality of plate sections.

9. An apparatus for distillation of feedstock, comprising:

a substantially enclosed distillation chamber with an inlet for receiving feedstock and an outlet for discharging feedstock;

a plate enclosed within the distillation chamber for supporting the feedstock in the distillation chamber;

the plate positioned parallel to a substantially horizontal plane across a portion of the distillation chamber;

a conveyor enclosed within the distillation chamber and extending longitudinally across the length of 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;

the paddles arranged in transverse rows, each row containing three or more paddles separated from one another a predetermined distance so that feedstock can pass between the paddles as the paddles move relative to the plate; and

the transverse position of the paddles in adjacent rows varied so that the feedstock is constantly agitated as the rows of paddles move relative to the plate.

10. The apparatus of claim 9, wherein each paddle has a substantially V-shaped cross-section, with a leading edge and two sides that angle outwardly from the leading edge toward the sides of the distillation chamber, and behind the leading edge in a direction opposite the movement of the paddles, so that as the paddles move through the feedstock, they separate and move the feedstock in a forward and lateral direction.

11. The apparatus of claim 10, wherein, when each paddle is positioned adjacent the plate so that it is agitating the feedstock, each paddle is positioned at a negative acute angle relative to the conveyor so that as the paddles move through the feedstock, the feedstock is driven upward over the top of the paddles.

12. The apparatus of claim 9, wherein the plate defines a plurality of transverse apertures extending transversely across a substantial portion of the width of the plate, and wherein the apparatus further comprises:

a plurality of heating rods for insertion into the apertures of the plate to heat the plate.

13. The apparatus of claim 12, further comprising:

a plurality of thermocouples for insertion into the apertures of the plate to measure temperature of the plate.

14. The apparatus of claim 9, wherein the cross-sectional shape of the distillation chamber includes a substantially horizontal bottom, two substantially vertical sidewalls, and a top having pitched sides meeting at a curved peak, so that as gasses are produced by the distillation process the shape of the chamber will encourage mixing of the gasses in the top thereof.

15. The apparatus of claim 9, wherein the plate comprises a plurality of plate sections.
