Pump feeder and method of mixing edible material

A pump feeder comprising:

• a hopper configured to receive edible material, the hopper including an upper chamber and a lower chamber;
• a first mixing paddle located within the upper chamber;
• a second mixing paddle located within the upper chamber, the first and second mixing paddles being configured to cause movement of the edible material within the upper chamber, wherein the first mixing paddle is configured to cause movement of the edible material from a front portion of the upper chamber, past a central portion of the upper chamber, to a rear portion of the upper chamber, and the second mixing paddle is configured to cause movement of edible material from the rear portion of the upper chamber, past the central portion of the upper chamber, to the front portion of the upper chamber;
• a mixing shaft, wherein the pump feeder is configured such that rotation of the mixing shaft causes the first and second mixing paddles to revolve around an axis defined by the mixing shaft, and the first and second mixing paddles are angled with respect to the axis, wherein the first mixing paddle is located relatively closer to the front portion of the upper chamber, while the second mixing paddle is located relatively closer to the rear portion of the upper chamber;
• a first auger located within the lower chamber;
• a second auger located within the lower chamber, the first and second augers being configured to cause movement of the edible material from a first end of the lower chamber to a second end of the lower chamber;
• and
• an outlet region located at the second end of the lower chamber, the outlet region being configured to connect to an inlet of a pump.
