Abstract

The disclosure relates to methods and apparatuses for the production of cheese. In one embodiment, the disclosure relates to methods and apparatuses for making pasta filata cheese. In one embodiment, the disclosure relates to a barrel for a single auger extrude having angular sections of material.

First claim

What is claimed is:

1. A system comprising:
a barrel, the barrel comprising a length, a width, an inlet, an outlet, an interior chamber, and a plurality of angular outer wall elements, each angular outer wall element comprising a first sidewall portion, a second sidewall portion, and a curved bottom base;
wherein each first sidewall portion is welded directly to a second sidewall portion along the entire length of the barrel to form a plurality of continuous and smooth edged ribs that are free of crevices, each rib extending from the inlet to the outlet and protruding inward toward a central axis within the interior chamber of the barrel;
wherein the barrel comprises a middle flange positioned midway between the inlet and the outlet, wherein the middle flange is only welded at the ribs;

an auger, wherein at least a portion of the auger is positioned between the inlet and the outlet of the barrel; and
a jacket, wherein the jacket surrounds the barrel.

2. The system of claim 1 , wherein the angular wall elements are composed of a material selected from the group consisting of stainless steel, steel and aluminum.

3. The system of claim 2 , wherein the material is stainless steel.

4. The system of claim 1 , wherein the first sidewall portion coincides with a first sidewall axis and the second sidewall portion coincides with a second sidewall axis, and wherein the first and second sidewall axes extend to intersect at a vertex to form a central angle of about 15° to about 25°.

5. The system of claim 1 , wherein the first sidewall portion coincides with a first sidewall axis and the second sidewall portion coincides with a second sidewall axis, and wherein the first and second sidewall axes extend to intersect at a vertex to form a central angle of 20°.

6. The system of claim 1 , wherein the jacket is positioned such that a gap exists between the jacket and the barrel, wherein the gap comprises at least ⅜ inches.

7. The system of claim 6 , wherein the jacket comprises a water inlet configured to allow water to flow through the gap between the jacket and the barrel.

8. The system of claim 1 , wherein the barrel comprises at least six angular outer wall elements.

9. The system of claim 7 , wherein the system further comprises a hopper element, wherein the hopper element is connected to the barrel inlet.

10. A method of preparing pasta filata cheese using the system of claim 9 , comprising inputting a dairy product into the hopper element and collecting a processed dairy product from the barrel outlet.

11. The method of claim 10 , further comprising flowing water through the gap between the jacket and the barrel at a flow rate of about 15 to about 25 gallons per minute.
