A comestible freezer has a freezing barrel with a cold wall, an input end and an output end and a feeder therewithin having a ribbon auger flight helix and a stationary blending bar within the helix. A portion of the ribbon auger flight helix has an outward twist or skew diverging from a radial plane through the axis of the helix and outwardly toward the barrel wall whereby to exert a component of thrust on the comestible toward the cold wall. A portion of the ribbon also has an inward twist or skew diverging from the radial plane and inwardly toward the blending bar whereby to exert a component of thrust on the comestible toward the bar.

In a comestible freezer having a freezing barrel with an input end and an output end and a feeder therewithin having an auger ribbon flight helix, the improvement in which the ribbon of the flight helix is skewed with respect to a radial plane through the axis of the helix whereby to exert a radial component of thrust on the comestible and in which the freezer has a fixed blending bar within said helix, said flight ribbon being skewed inwardly toward said blending bar for a portion of its length adjacent the output end whereby to exert a component of thrust on said comestible toward said bar, and in which the freezer has a cold wall, a portion of the flight ribbon adjacent the input end being skewed outwardly toward said cold wall whereby to exert a component of thrust on said comestible toward said cold wall.
