Feeding organic material to a heated surface

1. Apparatus for vaporization of powdered material, comprising:

(a) one or more containers each containing possibly distinct powdered materials each having at least one component;

(b) means for fluidizing the powdered material in each container;

(c) means defining a vaporization zone that is thermally isolated from at least one of the containers;

(d) transporting means for receiving fluidized powdered material from each container and delivering such fluidized powdered materials to the vaporization zone; and

(e) means for vaporizing the delivered fluidized powdered materials at the vaporization zone by applying heat.

2. The apparatus according to claim 1 where the transporting means is divided into a first stage transporting means and a second stage transporting means.

3. The apparatus of claim 2 where the first stage transporting means includes an auger mechanism or a translational member.

4. The apparatus of claim 2 where the second stage transporting means includes a rotating disk or a translational member.

5. The apparatus according to claim 1 where the transporting means has a single stage and includes a rotating disk or translational member.

6. The apparatus of claim 1 where the transporting means contains a plurality of cells, each cell receiving a predetermined amount of fluidized powder material.

7. The apparatus of claim 6 where the cells have at least one first size receiving a first predetermined amount of fluidized powder material and at least a second size receiving a second predetermined amount of fluidized powder material.

8. The apparatus of claim 7 where the fluidized powder material in the cell of the first size is delivered from a first container of fluidized powder material and the fluidized powder in the cell of the second size is delivered from a second container of fluidized powder material, where the fluidized powder material of the first container is different from the fluidized powder material of the second container.

9. The apparatus of claim 1 wherein the transporting means includes a screen having openings and the openings are sized to capture fluidized powdered material.

10. The apparatus of claim 6 further including wiping means for removing excess fluidized powder material from the cells and from interstitial areas between cells.

11. The apparatus of claim 1 wherein the transport means includes a moveable member and means for electrostatically transferring fluidized powdered material to the moveable member from the container.
