- a blending container;
- auger means displacable into and out of said blending container;
- said auger means being rotatable within said container for mixing ingredients contained in said blending container and having cutter means rotatable with respect to said auger means, said cutter means being rotatable at a different angular velocity from said auger means and in the same angular direction as said auger means, said cutter means being effective to cut large poritons of said ingredients contained in said blending container into smaller portions; and
- means for causing recirculation of at least a portion of the ingredients within the container during mixing.
- 2. A blending apparatus according to claim 1 wherein said auger means includes a fluted portion for advancing materials in a first direction and notch means formed in said auger means for permitting flow of said materials in a direction generally opposite to said first direction to effect said recirculation.
- 3. A blending apparatus according to claim 1 including means for uniformly lowering the temperature of the inner surface of the blending container.
- 4. Apparatus according to claim 3 wherein said means for lowering the temperature of the inner surface of the blending container comprises a cooling ring on at least a portion of said blending container and means for lowering the temperature of said cooling ring.
- 5. Apparatus according to claim 4 wherein said cooling ring is in surface contact with the external surface of said blending container and said means for lowering the temperature of said cooling ring is secured to said cooling ring.
- 6. Apparatus according to claim 1, 2, 3, 4 or 8 including means for rotating said auger means and means for rotating said cutter means at an angular velocity which is not equal to the angular velocity of rotation of said auger means.
- 7. Apparatus according to claim 1, 2, 3, 4 or 5 wherein said auger means is mounted on a first shaft, said cutter means is mounted on a second shaft, and wherein said first and second shafts are concentric.
- 8. Apparatus according to claim 6 wherein said auger means is mounted on a first shaft, said cutter means is mounted on a second shaft, and wherein said first and second shafts are concentric.
