Desolventizer toaster
An improved desolventizer toaster. The invention includes a housing. Within the housing, a first set of trays and a second set of trays are mounted. The first trays and second trays are disposed such that they are generally vertically spaced from one another and in a generally parallel disposition with respect to each other. Means for mixing vapors are provided, and they are positioned in a vapor mixing zone which is intermediate the first set of trays and second set of trays.
1. A desolventizer toaster (DT) comprising:
a housing containing a plurality of generally parallel, vertically spaced trays therewithin, a first set of the plurality of trays each having a peripheral edge engaging an inner surface of a wall defining the housing, and a second set of the plurality of trays each having an edge, generally concentric to, and spaced inwardly from said inner surface of said wall defining the housing,
an annular baffle positioned inside of the housing and being configured to restrict fluid passage between the inner surface of the wall defining the housing and the edge of the trays in the second set of trays, thereby causing lower density fluid passing upwardly from said first set of trays and higher density fluid passing downwardly from said second set of trays to intermix.
2. The desolventizer toaster in accordance with claim 1 , wherein said wall defining said housing includes an axially extending annular zone which is generally conical in shape.
3. The desolventizer toaster in accordance with claim 2 , wherein the annular baffle extends radially outwardly from a lowermost of said second trays within said annular zone.
4. The desolventizer toaster in accordance with claim 3 further comprising an annular tube manifold having a multiplicity of circumferentially spaced orifices directing steam radially outwardly to facilitate mixing of vapors.
5. A desolventizer toaster, comprising:
(a) a housing;
(b) a first set of trays mounted within said housing, said first trays being disposed generally vertically spaced and parallel to each other and having peripheral edges engaging an inner surface of a wall defining the housing;
(c) a second set of trays mounted within said housing, said second trays being disposed generally vertically spaced and parallel to each other and to said first set of trays, said second set of trays each having an edge spaced inwardly from said inner surface; and
(d) means for mixing vapors in a vapor mixing zone located between said first set of trays and said second set of trays.
6. A desolventizer toaster in accordance with claim 5 wherein said means for mixing vapors comprises an annular tube manifold having a multiplicity of circumferentially spaced orifices directing steam radially outwardly to facilitate mixing of vapors.
7. A desolventizer in accordance with claim 5 wherein said means for mixing vapors comprises a plurality of axially extending small ducts running external to said housing between said first set of trays and said second set of trays.
8. A desolventizer in accordance with claim 5 wherein said means for mixing vapors comprises an internal baffle.
