  "abstract": "An apparatus, a loop burner element, and a method for surface-roasting a food product wherein the roasting apparatus comprises (a) a conveyor which carries the food product and (b) at least one non-linear ribbon flame burner element or element assembly which preferably applies a ribbon flame to at least the upper and side surfaces of the food product as it is conducted through the roasting apparatus.",
  "claims": [
    "1. A method of processing a food product comprising a step of surface-roasting said food product by continuously delivering said food product through a roasting apparatus comprising a conveyor which carries said food product, and a plurality of ribbon flame burner elements or element assemblies which apply a ribbon flame to said food product, wherein each said ribbon flame burner element or element assembly includes an upper segment over said conveyor which applies an upper portion of said ribbon flame on a top portion of said food product, a first side segment which extends downwardly and applies a first side portion of said ribbon flame on a first side portion of said food product, and a second side segment which extends downwardly and applies a second side portion of said ribbon flame on a second side portion of said food product; wherein each said ribbon flame burner element or element assembly is arranged relative to the others so that the food product when being conveyed past said ribbon flame burner elements or element assemblies is continuously subjected to a ribbon flame; and wherein each said ribbon flame burner element or element assembly is oriented at a forwardly leaning angle or a rearwardly leaning angle with respect to a direction of travel of said conveyor in said housing, said forwardly leaning angle being in a range of from about 5° to about 60° from vertical and said rearwardly leaning angle being in a range of from about 5° to about 60° from vertical.",
    "2. The method of claim 1 wherein said upper segment has a curved shape.",
    "3. The method of claim 1 comprising more than one of said linear ribbon flame burner elements or element assemblies wherein at least one of said ribbon flame burner elements or element assemblies is oriented at said forwardly leaning angle with respect to said direction of travel of said conveyor and at least one of said ribbon flame burner elements or element assemblies is oriented at said rearwardly leaning angle with respect to said direction of travel of said conveyor.",
    "4. The method of claim 3 comprising a series of at least four of said ribbon flame burner elements or element assemblies which are alternately oriented at said forwardly leaning angle and said rearwardly leaning angle with respect to said direction of travel of said conveyor.",
    "5. The method of claim 1 wherein each said ribbon flame burner element or element assembly further comprises a lower segment which extends beneath said conveyor which applies a lower portion of said ribbon flame on a bottom portion of said food product.",
    "6. The method of claim 5 wherein said food product is an already cooked food product comprised of meat, poultry, or fish product.",
    "7. The method of claim 6 wherein said food product is an already cooked ham product.",
    "8. The method of claim 7 wherein said already cooked ham product has an exterior layer of fat thereon.",
    "9. The method of claim 7 wherein said already cooked ham product has a coating thereon, said coating comprising honey, sugar, caramel, a spice mix, barbecue sauce, a dry rub, chili powder or flake, paprika, an herb, salsa, or a combination thereof.",
    "10. The method of claim 7 wherein said already cooked ham product is a cooked emulsified ham product which has been prepared from an emulsion having honey, caramel, or a combination thereof included in said emulsion.",
    "11. The method of claim 6 further comprising the step, prior to said step of surface-roasting, of applying liquid smoke or other browning agent to said already cooked food product.",
    "12. The method of claim 6 further comprising the step, following said step of surface roasting, of packaging said already cooked food product wherein said already cooked food product is not conducted through, or otherwise placed in, any cooling apparatus operating at more than 10° F. below room temperature conditions between said step of surface-roasting and said step of packaging.",
    "13. The method of claim 5 wherein said method further comprises the steps of: cooking said food product by continuously delivering said food product through an oven which is different from said roasting apparatus and delivering at least a portion of a vapor product produced in said roasting apparatus into said oven such that said food product is cooked in said oven in an environment comprising at least a portion of said vapor product produced in said roasting apparatus.",
    "14. The method of claim 13 wherein said oven is a spiral oven having a conveyor which conveys said food product within said oven in a spiral pattern.",
    "15. The method of claim 13 wherein said food product is cooked in said step of cooking prior to said step of surface-roasting.",
    "16. The method of claim 5 further comprising the steps of: extracting from said roasting apparatus, at an extraction rate, a vapor product produced in said step of surface-roasting and automatically controlling said extraction rate to maintain a selected temperature condition of said vapor product.",
    "17. The method of claim 5 wherein each said ribbon flame burner element or element assembly is a non-linear ribbon flame burner element which forms a continuous loop through which said food product is continuously delivered in said step of surface-roasting, said continuous loop comprising said upper segment, said first side segment, said second side segment, and said lower segment.",
    "18. The method of claim 17 wherein said ribbon flame forms a continuous flame loop through which said food product is continuously delivered in said step of surface-roasting, said continuous flame loop comprising said upper portion of said ribbon flame, said first side portion of said ribbon flame, said second side portion of said ribbon flame, and said lower portion of said ribbon flame.",
    "19. The method of claim 18 wherein: said continuous loop has a continuous flame slot provided therein and said continuous loop further comprises a ribbon flame element in said continuous flame slot, said continuous flame loop being discharged from said ribbon flame element."
