Abstract

Abstract The present invention relates to a method and apparatus for smoking foods. An enclosure is presented which is characterized by an absence of any ventilating means. The enclosure is substantially air tight. Hickory or other exotic wood blocks or chips are used as the source of smoke and an electric heating element raises the temperature in the enclosure to approximately 200°-300° F. This activates the wood and produces the desired smoke. The increase in temperature also produces an increase in pressure within the enclosure which in turn causes a pressure differential between the inside and the outside of any food being processed. This forces smoke and wood resins to permeate the meat and enhance the food with the desired smoke flavor. The enclosure in which the food is smoked is also of unique design in that the back wall is presented in three planes so as to avoid forming any right angles with any other sidewalls. Two panels of the back wall extend at an obtuse angle to the third central panel and to the adjacent sidewalls. Also, the food supporting shelves are spaced from the sidewalls a short distance. This provides for maximum circulation of heat and smoke and the absence of 90° angles helps prevent "hot spots" from forming. All of the food supporting structure may be easily removed to facilitate cleaning. To this end, the absence of 90° corners is of substantial benefit in preventing excessive build up of grease, etc. and also makes it easier to remove any foreign matter which does accumulate.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 175 words
A device for cooking and imparting flavor to foods comprising: an enclosure characterized by substantially air tight construction and an absence of any source of outside air, said enclosure presenting a substantially box-like compartment having an opening at one side thereof, said compartment being characterized by a sidewall opposite said one side which sidewall does not present any 90° angles with any other sidewalls, said enclosure being adapted to receive means for producing flavor imparting gases or vapors upon being heated; door means pivotally coupled with said enclosure for closing said compartment opening, locking means for said door means comprising an elongated bar extending substantially the length of the door, means for pivotally mounting said bar on said enclosure and handle means for moving said bar from a locking to an unlocking position; and means for raising the temperature in said enclosure to an elevated level high enough to effect cooking of the food while also effecting production of gases or vapors from said flavor producing means and simultaneously increasing the pressure in said enclosure.
Claim 2
Independent Claim 175 words
A device for cooking and imparting flavor to foods comprising: an enclosure characterized by substantially air tight construction and an absence of any source of outside air, said enclosure presenting a substantially box-like compartment having an opening at one side thereof, said compartment being characterized by a sidewall opposite said one side which sidewall does not present any 90° angles with any other sidewalls, said enclosure being adapted to receive means for producing flavor imparting gases or vapors upon being heated; door means pivotally coupled with said enclosure for closing said compartment opening, locking means for said door means comprising an elongated bar extending substantially the length of the door, means for pivotally mounting said bar on said enclosure and handle means for moving said bar from a locking to an unlocking position; and means for raising the temperature in said enclosure to an elevated level high enough to effect cooking of the food while also effecting production of gases or vapors from said flavor producing means and simultaneously increasing the pressure in said enclosure.
Claim 3
Dependent Claim 43 words
A device as set forth in claim 1, wherein is included means for holding a quantity of a substance capable of releasing smoke upon heating; and said heating means comprises an electric heating element disposed in closely spaced relationship to said holding means.
Claim 4
Dependent Claim 25 words
A device as set forth in claim 2, wherein said heating means is operable to raise the temperature of said enclosure to approximately 200°-300° F.
Claim 5
Dependent Claim 28 words
A device as set forth in claim 3, wherein said heating element is disposed beneath said holding means and including heat reflector means disposed beneath said heating element.
