1. In a high volume food loaf slicing machine of the kind comprising:
- a loaf support, supporting a food loaf for movement along a downwardly inclined path;
loaf feed conveyor means, positioned at the lower end of the food loaf path, for continuously advancing a food loaf along that path and into a slicing station;
a rotary knife, supported for orbital movement into and out of the slicing station in a direction transverse to the food loaf path, for cyclically cutting individual slices from the loaf as the loaf enters the slicing station, and contained within a blade housing wherein said blade housing comprises upper and lower blade housings;
variable speed main drive motor means;
knife orbit drive connection means, connecting the main drive motor means to the knife to drive the knife through its orbital movement at a slicing rate determined by the speed of the main drive motor means;
conveyor drive connection means, connecting the main drive motor means to the loaf feed conveyor means to drive the conveyor means at a loaf feed rate determined in part by the speed of the main drive motor means;
variable speed knife rotation motor means, connected to the knife to drive the knife through its rotary motion at a cutting rate determined by the speed of the knife rotation motor means and independent of the speed of the main drive motor means;
and a sliced food stacker comprising two pair of stacker grids mounted on vertically movable rotatable support shafts, said stacker located immediately below the slicing station.the improvement comprising;
a large air baffle forming a substantially continuous wall adjacent to the open area of the lower blade housing, said lower housing bounding said large baffle on its ends and bottom, said large baffle bounded on its top by the rotating knife blade as it rotates over it;
a small air baffle mounted on the lower blade housing perpendicular to the plane of the knife blade and radially from the rotary knife orbiter, said small baffle bounded on its bottom and one end by the lower blade housing and on its other end by the rotating blade orbiter and on top by the rotating blade;
and a vent port formed in the lower blade housing wherein said port is sufficiently sized and shaped to allow turbulent air generated by the rotating knife blade to flow down and out of the blade housing rather than over the product to be sliced.

Abstract
A high volume food loaf slicing machine in which a rotating and orbiting knife slices the loaf as it advances through a slicing station. The turbulent air generated by the rotating and orbiting knife is reduced in the vacinity of the stacking slices by baffles and is redirected through a vent port and away from the stacking slices.
