Abstract: An apparatus for vertical transfer of whole nuts from a first elevation to a second, lower elevation includes a run extending between an entrance and an exit, and having a plurality of alternatingly arranged conveying panels between the entrance and the exit. Each conveying panel is inclined to horizontal and has a variable effective conveying width. The apparatus further includes arcuate turn-arounds disposed between respective conveying panels to facilitate transferring the nuts from one conveying panel to the next lower conveying panel. 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.

Abstract: An apparatus for vertical transfer of whole nuts from a first elevation to a second, lower elevation includes a run extending between an entrance and an exit, and having a plurality of alternatingly arranged conveying panels between the entrance and the exit. Each conveying panel is inclined at approximately 30 degrees to horizontal and has a predefined width. The apparatus further includes arcuate turn-arounds disposed between respective conveying panels to facilitate transferring the nuts from one conveying panel to the next lower conveying panel. The predefined width of the conveying panels 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.
