Method for heating foodstuffs
First Claim
1. A method for heating meat products, the method comprising the steps of:
- (a) producing an uncooked mixture comprising uncooked meat pieces at an initial temperature; and
(b) forcing the uncooked mixture through a flow resistance tube at a heating velocity to produce frictional resistance heating in the uncooked mixture and raise the temperature of the uncooked mixture to a final temperature above the initial temperature, thereby converting the uncooked mixture to a processed mixture.

Abstract
A method for heating foodstuffs, particularly mixtures made up of small pieces of meat, comprises pressurizing the uncooked mixture to force the mixture through a flow resistance device (22) at a heating velocity. Sufficient force is applied to the uncooked mixture to produce frictional resistance heating in the uncooked mixture as the mixture travels through the flow resistance device (22). The frictional resistance heats the uncooked mixture from an initial temperature to a final temperature which may be above a cooking temperature. This final temperature converts the uncooked mixture to a desired processed mixture. The invention may also include forming the processed mixture into a desired shape and cooling the processed mixture to a setting temperature. A variable resistance device (40) may be included in the flow resistance device (22) and used to control the level of heating in the foodstuffs.

13. A method for heating meat products, the method comprising the steps of:
-
(a) producing an uncooked mixture comprising uncooked meat pieces at an initial temperature; (b) pressurizing the uncooked mixture to a processing pressure; and (c) directing the pressurized uncooked mixture through a flow resistance tube while maintaining a reduced pressure at an outlet end of the flow resistance tube, the resistance to the flow of the uncooked mixture through the flow resistance tube raising the temperature of the uncooked mixture to a processed temperature and thereby converting the mixture to a processed mixture. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method of heating foodstuffs, the method comprising the steps:
-
(a) producing an input mixture comprising pieces of foodstuffs at an initial temperature; and (b) applying a force to the input mixture to displace the input mixture through a flow resistance tube to produce frictional heating in the input mixture, the frictional heating generated during the displacement through the flow resistance tube raising the temperature of the input mixture from the initial temperature to a processing temperature. - View Dependent Claims (24, 25, 26, 27)
