ABSTRACT:
An apparatus for evenly distributing powdered and granular food product ingredients at a controlled and variable rate. A delivery tube communicates with the interior of a hopper that holds a supply of the ingredient and an auger causes the ingredient to move from the hopper and axially along the tube. The auger has a central body with a large diameter portion extending through the hopper, a small diameter portion disposed within the tube and a land extending along and around the body to define a generally helical flute that serves as an ingredient flow path of variable cross-sectional area. A series of non-circular openings arranged along the tube allow the ingredient to escape in a uniform manner, the effective size of the openings being variable by changing the relative rotational positions of the tube and an apertured sleeve that surrounds the tube. The positions of the openings is also variable by rotating the tube and the sleeve together to further improve the uniformity of distribution.
