CLAIMS

What is claimed is:

1. A device comprising:

a first plate;

a second plate attached to the first plate, at least one of the first plate and the second plate comprising energy exchanging capabilities; and

a first spacer and a second spacer arranged between the first plate and the second plate, wherein the first plate, the second plate, the first spacer and the second spacer define at least one passage for a product to pass through the device.

2. The device of claim 1 wherein the first plate and the second plate define a temperature controlled zone.

3. The device of claim 2 wherein at least one of the first plate and the second plate comprises a passage through a portion of the first plate and the second plate.

4. The device of claim 3 wherein the passage comprises a fluid that cools or heats the temperature controlled zone of the device.

5. The device of claim 1 wherein the first plate and the second plate define a plurality of temperature controlled zones.

6. The device of claim 5 wherein at least one of the first plate and the second plate comprises a plurality of separate passages through individual portions of the first plate and the second plate.

7. The device of claim 6 wherein the passages comprise a fluid that cools or heats the temperature controlled zones of the device.

8. The device of claim 1 wherein the passage comprises a gap between the first plate and the second plate ranging from about 3 cm to about 15 cm.

9. The device of claim 1 wherein the first spacer and the second spacer are T-shaped.

10. The device of claim 1 wherein the first plate and the second plate are sealed along the first spacer and the second spacer to withstand internal pressures in the passage from about 50 to about 1500 psi.

11. The device of claim 1 wherein the first plate and the second plate are attached together by at least one bolt, screw, or clamp.

12. The device of claim 1 comprising a first end plate defining an inlet and a second end plate defining an outlet attached to opposite ends of the first plate and the second plate.

13. A heat exchanger comprising:

a first pressure plate and a first energy exchanging plate attached to the first pressure plate; a second pressure plate and a second energy exchanging plate attached to the second pressure plate, the second pressure plate attached to the first pressure plate; and

a first spacer and a second spacer arranged between the first energy exchanging plate and the second energy exchanging plate, wherein the first energy exchanging plate, the second energy exchanging plate, the first spacer and the second spacer define at least one temperature controlled passage for product to pass through the heat exchanger.

14. The heat exchanger of claim 13 wherein at least one of the first energy exchanging plate and the second energy exchanging plate comprises a passage through a portion of the first energy exchanging plate and the second energy exchanging plate.

15. The heat exchanger of claim 14 wherein the passage comprises a fluid that cools or heats the temperature controlled zone of the heat exchanger.

16. The heat exchanger of claim 13 wherein the first energy exchanging plate and the second energy exchanging plate define a plurality of temperature controlled zones.

17. The heat exchanger of claim 16 wherein at least one of the first energy exchanging plate and the second energy exchanging plate comprises a plurality of separate passages through individual portions of the first energy exchanging plate and the second energy exchanging plate that define the temperature controlled zones.

18. The heat exchanger of claim 17 wherein the passages comprise a fluid that cools or heats the temperature controlled zones of the heat exchanger.

19. The heat exchanger of claim 13 wherein the passage comprises a gap between the first energy exchanging plate and the second energy exchanging plate ranging from about 3 cm to about 15 cm.

20. The heat exchanger of claim 13 wherein the first spacer and the second spacer are T-shaped.

21. The heat exchanger of claim 13 wherein the first energy exchanging plate and the second energy exchanging plate are sealed along the first spacer and the second spacer to withstand internal pressures in the product passage from about 50 to about 1500 psi.

22. The heat exchanger of claim 13 comprising at least one transitioning gasket attached to the inlet of the heat exchanger.

23. The heat exchanger of claim 13 wherein the first pressure plate and the second pressure plate are attached together by at least one bolt, screw, or clamp.

24. The heat exchanger of claim 13 comprising a first end plate defining an inlet and a second end plate defining an outlet, the first end plate and the second end plate attached to opposite ends of the first pressure plate and the second pressure plate.

25. A method for making a food product comprising introducing a meat emulsion into a heat exchanger and subjecting the meat emulsion to a high pressure, the heat exchanger comprising a first plate, a second plate attached to the first plate, and a first spacer and a second spacer arranged between the first plate and the second plate, wherein the first plate, the second plate, the first spacer and the second spacer define at least one temperature controlled passage for the meat emulsion to pass through the heat exchanger.

26. The method of claim 25 comprising controlling a temperature of the heat exchanger by passing a fluid through at least one passage of a portion of at least one of the first plate and the second plate.

27. The method of claim 25 wherein the first plate and the second plate define a plurality of individual temperature controlled zones.

28. The method of claim 27 comprising controlling temperatures of individual temperature controlled zones by passing a fluid through a plurality of separate passages through individual portions of the first plate and the second plate.

29. A method for making a meat emulsion product comprising:

forming a meat emulsion containing protein and fat;

comminuting and heating the meat emulsion;

introducing the meat emulsion into a heat exchanger and subjecting the meat emulsion to a pressure of at least 50 psi., the heat exchanger comprising a first plate, a second plate attached to the first plate, and a first spacer and a second spacer arranged between the first plate and the second plate, wherein the first plate, the second plate, the first spacer and the second spacer define at least one temperature controlled passage for the meat emulsion to

pass through the heat exchanger; and discharging the meat emulsion from the heat exchanger.

30. The method of claim 29 comprising packaging and retorting the discharged meat emulsion product.

31. The method of claim 29 comprising drying the discharged meat emulsion and forming a kibble-like piece from the meat emulsion.
