Claim 6

The roasting oven and cooling apparatus of claim 2 wherein said cooling means comprises means selectively operable to percolate cold air through said product received from said closed environment, for displacing heat held by said product.

Claim 7

The roasting oven and cooling apparatus of claim 4 wherein said cooling means further comprises side walls containing said received nut product and having means for maintaining said sidewalls at refrigerated temperatures.

Claim 8

The roasting oven and cooling apparatus of claim 5 wherein said means for maintaining said sidewalls at refrigerated temperatures includes pneumatic coils positioned adjacent said sidewalls and supplied with refrigerant fluids.

Claim 9

The roasting oven and cooling apparatus of claim 2 further including a plurality of said rotatable containers, wherein said containers are mounted at the extremity of a structure having a center of rotation about which all said containers are rotated, and further including means for rotating said structure and said plurality of containers about said center of rotation.

Claim 10

The roasting oven and cooling apparatus of claim 7 wherein said center of rotation is horizontally oriented so that during a cycle of rotation, said containers pass through a lower elevation and successively a higher elevation, and wherein each of said rotatable container doors is positioned at a surface of said container substantially at the furtherest distance from said center of rotation, said door being maintained selectively in an opened state by gravity during its pass through said lower elevation to evacuate by gravity all product from said container.

Claim 11

A roasting oven and cooling apparatus, comprising: a. at least one rotatable container having perforations for draining treated and untreated liquids and capable of holding a quantity of nut, bean and seed-like product; b. a closed environment completely enclosing said rotatable container, having means for separately and gravitationally evacuating liquid and for separately and gravitationally evacuating said product, said means comprising guidemeans positioned within said closed environment below said at least one rotatable container and having at least two operational modes, said guidemeans being selectively operable to provide in one mode of operation a guideway for said product and for said liquid substantially to a side of said enclosed environment defining a vector of movement of said product and said liquid in downward and horizontal directions, and selectively operable to provide in a second mode of operation a passage for heat energy vertically through said guidemeans such that heat from said heating means within said closed environment may pass through said guidemeans to said at least one rotatable container, and further having means for receiving said product; c. means within said closed environment for heating and cooling said environment at predetermined times; d. container moving means for providing translational movement of said container through the air within said closed environment; and e. cooling means in connection with said closed environment for receiving said product from said means for separately and gravitationally evacuating said product.

Claim 12
