Abstract

Claims (22)

1. An apparatus for vertical transfer of whole nuts from a first elevation to a second, lower elevation, the apparatus comprising:

a run extending between an entrance and an exit, and including a plurality of alternatingly arranged conveying panels;

each conveying panel inclined to horizontal and having a variable effective conveying width; and

at least one arcuate turn-around disposed between respective conveying panels;

wherein the variable effective conveying width is selected based on a predetermined mass flow rate of nuts such that whole nuts move along the run in a continuous stream without tumbling, and wherein each nut is in contact with adjacent nuts in its respective layer;

each conveying panel having an undulating cross-sectional shape along at least part of the panel length in a direction of the run, the undulating cross-sectional shape forming peaks and troughs that define at least one channel for transferring the continuous stream of nuts;

the at least one channel defining at least part of the variable effective conveying width.

2. The apparatus of claim 1 , wherein;

the undulating cross-sectional shape defines at least one peak height;

the variable effective width has a first value when a height of the stream of nuts does not exceed the at least one peak height such that the nuts flow only within the at least one channel; and

the variable effective width has a second value when the height of the stream of nuts exceeds the at least one peak height.

3. The apparatus of claim 2 , wherein:

the undulating cross-sectional shape defines at least a first peak height and a second peak height greater than the first peak height;

the variable effective width has a first value when the height of the stream of nuts does not exceed the first peak height, such that the nuts flow only within channels formed by the first peak height;

the variable effective width has a second value when the height of the stream of nuts exceeds the first peak height, but does not exceed the second peak height; and

the variable effective width has a third value when the height of the stream of nuts exceeds the second peak height.

4. The apparatus of claim 1 , wherein each conveying panel is inclined at approximately 30 degrees to horizontal.

5. A method of vertically transferring whole nuts from a first elevation to a second, lower elevation, the method comprising:

providing whole nuts to a transfer apparatus having a run extending between an entrance and an exit, and including a plurality of alternatingly arranged conveying panels between the entrance and exit, each conveying panel inclined relative to horizontal and having a variable effective conveying width;

wherein the variable effective conveying width is selected based on a predetermined mass flow rate of nuts such that whole nuts move along the run in a continuous stream without tumbling, and wherein each nut is in contact with adjacent nuts in its respective layer;

each conveying panel having an undulating cross-sectional shape along at least part of the panel length in a direction of the run, the undulating cross-sectional shape forming peaks and troughs that define at least one channel for transferring the continuous stream of nuts;

the at least one channel defining at least part of the variable effective conveying width.
