Extractor
An extractor which provides significant features over structures known in the prior art. The present improved structure employs nozzles which eject a jet of fluid upwardly into a granular or flake product being conveyed on a transfer conveyor.
1. An extractor, comprising:
a porous screen on which material to be processed is deposited for transmission along an axis; and
a fluid passage formed through the porous screen and over a plenum mounted to an underside of the porous screen, the plenum being in fluid communication with a reservoir of fluid and configured to eject the fluid upwardly through the fluid passage and into the material to be processed on an upper surface of the porous screen, thereby influencing a texture of the material to be processed.
2. The extractor in accordance with claim 1 wherein said fluid passage comprises a slit extending substantially a full width of said porous screen in a disposition generally perpendicular to said axis.
3. The extractor in accordance with claim 2 further comprising agitation means mounted within said plenum.
4. The extractor of claim 1 , wherein said porous screen comprises a blank section and said fluid passage comprises a slit extending generally perpendicular to said axis, said plenum being positioned to eject the fluid upwardly through the slit and into the porous screen and material to be processed deposited thereon.
5. An extractor, comprising:
conveyor means on which granular or flake material is deposited for transmission from a first end to a second end, said conveyor means comprising alternating segments of porous material and blank sections; and
a plurality of nozzles positioned in each blank section of said conveyor means, each of said plurality of nozzles being configured to direct a jet of fluid upwardly into the granular or flake material, thereby causing the jet of liquid to disperse into of the granular or flake material and influence a contour of the granular or flake material.
6. The extractor in accordance with claim 5 wherein said conveyor means is porous.
7. The extractor in accordance with claim 5 further comprising a manifold mounted to an underside of each blank section of said conveyor means, said manifold being in fluid communication with a plurality of generally linearly aligned orifices formed therein to thereby provide the plurality of nozzles.
8. The extractor in accordance with claim 7 further comprising a source of fluid in fluid communication with said manifold to deliver fluid to said manifold.
9. The extractor in accordance with claim 8 wherein said manifold comprises a pipe, and wherein said plurality of generally linearly aligned orifices are aligned along a first axis extending generally transverse to said run of said conveyor means.
10. The extractor in accordance with claim 9 further comprising agitation means mounted within a pipe manifold.
11. The extractor in accordance with claim 10 wherein said agitation means is configured to rotate about a second axis substantially parallel to said first axis.
12. The extractor of claim 5 , wherein said conveyor means comprises a screen.
