Definitions

  • ABSTRACT A deep fat dryer having a cooking pot, combustion chambers extending front-to-rear under the pot, burners adjacent front ends and a vertical flue at rear ends of combustion chambers, characterized by a horizontal bottom wall for the flue with an air intake opening of less area than the horizontal area of the flue, and a cool air scoop secured along its rear edge adjacent rear edge of opening and having a depending portion comprising a forwardly and downwardly inclined section and a horizontal section defining a free edge forwardly of the air intake opening spaced below the bottom flue wall a distance substantially sixty percent of the front-to-rear width of the air intake opening.
  • the principal object of this invention is to materially decrease the flue temperature, with the resulting elimination of a cabinet rear heat guard and lowering of the temperature of the pot rear wall, and to effectively reduce the recovery time of a deep fat fryer like that of US. Pat. No. 3,363,541.
  • FIG. 1 is a side elevation of a deep fat fryer embodying the invention, with parts broken away and parts in vertical section;
  • FIG. 2 is a detail horizontal section taken substantially on the line 2-2 of FIG. 1 on an enlarged scale.
  • reference numeral 11 indicates in general, a deep fat fryer embodying the features of this invention which is of generally similar construction to that disclosed in my referenced prior US. Pat. No. 3,363,541.
  • the fryer comprises a cooking pot, generally indicated by the reference numeral 25, which is made up of sidewalls 26, a front wall 27, a rear wall 28 and a multi-curved bottom 29.
  • This bottom 29 of the pot defines a pair of laterally spaced combustion chambers 31 extending longitudinally front-to-rear of the fryer between the front and rear walls 27 and 28.
  • a horizontal wall 35 defines the bottom of each of these combustion chambers 31.
  • the front and rear walls 27 and 28 and the laterally spaced lower portions of the curved bottom 29 and the sidewalls 26 define cool zones 36, as more fully described in US. Pat. No. 3,363,541.
  • the intermediate portion of the cooking pot 25 extending upwardly from the horizontal bottom walls away from the heat shield means 35 to a short distance above the uppermost portions of the pot bottom 29 comprises a fat-heating zone 37, while the upper portion of the pot defines the usual frying zone 38.
  • heat-supplying means in the form of upstanding burners 42 positioned to direct flames issuing therefrom rearwardly into their respective combustion chambers 31. It will be noted in FIG. 1 that the lowermost cool zones 36 of the pot 25 stope downwardly and forwardly to facilitate draining of the cooking fat therefrom through the agency of a manually operable drain valve 43.
  • the combustion chambers 31 communicate at their rear ends with a vertically disposed flue indicated generally herein by reference numeral 61.
  • a vertically disposed flue indicated generally herein by reference numeral 61.
  • the bottom of this vertical flue is closed and a safety fire wall unidentified by reference numeral is shown disposed in rear wardly spaced relationship to the flue as a heat guard.
  • such vertically disposed heat guard has been eliminated and a substantially horizontal wall 62 at the bottom of the flue 61 is provided with an air intake opening 63 of slightly less area than the horizontal area of the flue.
  • a cool air scoop indicated generally by reference numeral 64 is secured in any suitable manner along its rear marginal edge to the flue bottom wall 62 which defines the rear laterally extending edge of the opening 63.
  • This .cool air scoop 64 is made up of a depending portion comprising a downwardly and forwardly inclined section 65 and a substantially horizontal forwardly extending section 66 terminating in a free edge portion 67 which extends forwardly slightly beyond the front edge of the air intake opening 63.
  • cool air is directed by the scoop 64 upwardly through the intake opening 63 from the spaces between the pot cool zones 36 below the heat shields 35, as illustrated by the arrows 68 in FIG. 1, to move upwardly through the flue 61 principally adjacent its rear wall and mix with the products of combustion flowing into the flue from the combustion chambers 31, as illustrated by arrows 69 in FIG. 1.
  • the distance of the free edge 67 of the cool air scoop 64 below the bottom flue wall 62 has been found to be critical, although why this is true is not fully understood. However, it has been determined that such distance of the free edge 67 below the air intake opening 63 must be substantially 60 percent of the front-to-rear width of the opening 63. For example, in the preferred embodiment of a commercially rated 14 inch fryer with 135,000 Btu burner output, a flue of 4 inches and an air inlet opening of 3% inches front-to-rear, the free edge 67 of the cool air scoop 64 should be 2 inches below the bottom flue wall 62.
  • Rear wall kettle 150 130 13.3%
  • a deep fat fryer having a cooking pot, combustion chamber means extending front-to-rear under said pot, burner means adjacent the front of said pot for supplying heat to said combustion chamber means, and a vertical flue communicating with the rear of said combustion chamber means; a substantially horizontal wall at the bottom of said flue with an air intake opening of less area than the horizontal area of said flue, and a cool air scoop secured along one edge adjacent a transversely extending portion of said wall defining one laterally extending edge of said opening and having a depending portion terminating in a substantially horizontal free edge portion spaced below the other laterally extending edge of said opening, wherein said free edge of said scoop is spaced below said bottom flue wall a distance substantially sixty percent of the frontto-rear width of said air intake opening therein.
  • a deep fat fryer having a cooking pot, combustion chamber means extending front-to-rear under said pot, burner means adjacentthe front of said pot for supplying heat to said combustion chamber means, and a vertical flue communicating with the rear of said combustion chamber means; a substantially horizontal wall at the bottom of said foue with an air intake opening of less area than the horizontal area of said flue, and a cool air scoop secured along one edge adjacent a transversely extending portion of said wall defining one laterally extending edge of said opening and having a depending portion terminating in a substantially horizontal free edge portion spaced below the other laterally extending edge of said opening, wherein the rear edge of said scoop is that secured adjacent the rear edge of said air intake opening, and said depending portion comprises a downwardly and forwardly inclined section and a substantially horizontal forwardly extending section defining said free edge portion.
  • a deep fat fryer according to claim 2, wherein said free edge portion of said scoop extends forwardly beyond the front edge of said air intake opening.
  • a deep fat fryer according to claim 3, wherein said free edge of said scoop is spaced below said bottom flue wall a distance substantially sixty percent of the frontto-rear width of said air intake opening therein.
