Abstract
Abstract A method and apparatus for making jerky from food products including meat such as beef wherein the materials for making the jerky are ground to a desired consistency and blended with selected curing agents or seasoning, the cured or seasoned material then being extruded onto a freezer drum and compressed upon the drum to chill or freeze the material and to form a desired thickness for the jerky upon the drum, the frozen jerky then being removed from the freezer drum, cut to desired lengths and deposited upon a conveyor for passage through a drying chamber to first thaw and then dry the jerky strips in a continuous process. The jerky may also be smoked within the drying chamber if desired and transported to a packaging station from the drying chamber.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
150 words
In a method for manufacturing jerky, the steps comprising grinding or otherwise dividing selected jerky type materials to have a desired extrudable consistency, blending the divided materials with curing agents and seasonings selected for jerky preparation, providing a refrigerated rotating drum having a peripheral heat transfer surface, applying the blended material onto the heat transfer surface of the drum to form a uniform thickness sheet upon its heat transfer surface and maintaining the blended material in intimate contact with the heat transfer surface, cooling said sheet of blended material upon the heat transfer surface of the drum to form a solidified sheet suitable for cutting, removing said sheet of cooled, blended material from the drum and cutting it into individual jerky strips, and transferring the individual strips of jerky from the cutting station and transporting them through a drying chamber means for removing excess moisture from the individual jerky strips.
Claim 2
Dependent Claim
150 words
In a method for manufacturing jerky, the steps comprising grinding or otherwise dividing selected jerky type materials to have a desired extrudable consistency, blending the divided materials with curing agents and seasonings selected for jerky preparation, providing a refrigerated rotating drum having a peripheral heat transfer surface, applying the blended material onto the heat transfer surface of the drum to form a uniform thickness sheet upon its heat transfer surface and maintaining the blended material in intimate contact with the heat transfer surface, cooling said sheet of blended material upon the heat transfer surface of the drum to form a solidified sheet suitable for cutting, removing said sheet of cooled, blended material from the drum and cutting it into individual jerky strips, and transferring the individual strips of jerky from the cutting station and transporting them through a drying chamber means for removing excess moisture from the individual jerky strips.
Claim 3
Dependent Claim
41 words
The method of claim 1 wherein the temperature of the blended material is maintained sufficiently above the temperature of the heat transfer surface on the refrigerated drum in order to promote adhesion of the sheet of blended material to the drum.
Claim 4
Dependent Claim
49 words
The method of claim 1 wherein the blended material is heated to accelerate interaction with the selected curing agents and thereby reduce time necessary for curing, the blended and cured material thereafter being applied to the heat transfer surface of the drum to terminate action of the curing agent.
Claim 5
Dependent Claim
38 words
The method of claim 1 wherein the blended material is extruded into a sheet upon the refrigerated drum by means of a feed roller forming a nip in combination with the refrigerated drum for receiving the blended material.
Claim 6
Dependent Claim
55 words
The method of claim 4 further comprising the step of training an endless belt about the feed roller and about additional roller means in order to maintain the endless belt in contact with the sheet of blended material and to maintain the blended material in intimate contact with the heat transfer surface of the drum.
Claim 7
Dependent Claim
42 words
The method of claim 1 wherein the individual jerky strips removed from the refrigerated drum and passing through the cutting station are first thawed and then dried to remove excess moisture in order to permit storage of the strips at room temperature.
Claim 8
Dependent Claim
28 words
The method of claim 1 wherein the individual strips of jerky are transferred from the cutting station and transported through the drying chamber means in a continuous operation.
