Abstract
Abstract This invention provides novel apparatus for cooking food articles. Basically, the novel apparatus of the present invention comprises: a chamber; support means for locating food articles within the chamber with substantially all of their exterior surfaces being exposed; sump means having an inlet fluid-connected to the chamber for containing a liquid cooking medium; heater means for heating the liquid cooking medium contained in the sump; first sprayer means located within the chamber adjacent to a first side of the support means; second sprayer means located within the chamber adjacent to a second side of the support means that is opposite from the first side and being aligned in a common plane with the first sprayer means; and pump means fluid-connected to the sump means and to both of the sprayer means to admit to the chamber, through both of the sprayer means and onto the food articles supported thereon, a pressurized spray of liquid cooking medium in a pressure range betwen 10 and 70 p.s.i.g. that has been heated by the heater means but has not received any latent heat of vaporization therefrom so as to cause food articles supported on the support means to be clamped between the pressurized sprays respectively discharged by the first and second sprayer means and to be cooked thereby without being immersed therein.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
260 words
Apparatus for cooking food articles, comprising: a. a chamber; b. support means for locating food articles within said chamber with substantially all of their exterior surfaces being exposed; c. sump means having an inlet fluid-connected to said chamber for containing a liquid cooking medium. d. heater means for heating the liquid cooking medium contained in said sump means; e. first sprayer means located within said chamber adjacent to a first side of said suppot means; f. second sprayer means located within said chamber adjacent to a second side of said support means that is opposite from said first side and being aligned in a common plane with said first sprayer means; and g. pump means fluid-connected to said sump means and to both of said sprayer means to admit to said chamber, through both of said sprayer means and onto the food articles supported therein, a pressurized spray of liquid cooking medium in a pressure range between 10 and 70 p.s.i.g. that has been heated by said heater means but has not received any latent heat of vaporization therefrom so as to cause food articles supported on said support means to be clamped between the pressurized sprays respectively discharged by said first and second sprayer means and to be cooked thereby without being immersed therein, h. said sprayer means and said support means being movable relative to one another and drive means being provided for causing relative movement therebetween with said first sprayer means and said second sprayer means continuing to remain aligned in a common plane with one another.
Claim 2
Dependent Claim
260 words
Apparatus for cooking food articles, comprising: a. a chamber; b. support means for locating food articles within said chamber with substantially all of their exterior surfaces being exposed; c. sump means having an inlet fluid-connected to said chamber for containing a liquid cooking medium. d. heater means for heating the liquid cooking medium contained in said sump means; e. first sprayer means located within said chamber adjacent to a first side of said suppot means; f. second sprayer means located within said chamber adjacent to a second side of said support means that is opposite from said first side and being aligned in a common plane with said first sprayer means; and g. pump means fluid-connected to said sump means and to both of said sprayer means to admit to said chamber, through both of said sprayer means and onto the food articles supported therein, a pressurized spray of liquid cooking medium in a pressure range between 10 and 70 p.s.i.g. that has been heated by said heater means but has not received any latent heat of vaporization therefrom so as to cause food articles supported on said support means to be clamped between the pressurized sprays respectively discharged by said first and second sprayer means and to be cooked thereby without being immersed therein, h. said sprayer means and said support means being movable relative to one another and drive means being provided for causing relative movement therebetween with said first sprayer means and said second sprayer means continuing to remain aligned in a common plane with one another.
Claim 3
Dependent Claim
41 words
The invention of claim 1, further including control means connected to said heater means to control the temperature of the liquid cooking medium that is heated thereby such that no latent heat of vaporization is supplied thereto by said heater means.
Claim 4
Dependent Claim
40 words
The invention of claim 1, wherein: a. said first and second sprayer means are movable relative to said support means; and b. said drive means is constructed to cause rotary movement of said sprayer means relative to said support means.
Claim 5
Dependent Claim
56 words
The invention of claim 3, wherein said first and second sprayer means are fluid-conected to said sump and pump means through a conduit member that is mounted for rotation relative to said chamber and said support means and is interconnected to said drive means for rotary movement thereby relative to said chamber and said support means.
Claim 6
Dependent Claim
70 words
The invention of claim 4, further including control means connected to said heater means to control the temperature of the liquid cooking medium that is heated thereby such that no latent heat of vaporizaton is supplied thereto by said heater means, wherein said control means can control to within ±2° F. the desired temperature to which the liquid cooking medium is to be heated and maintained by said heater means.
Claim 7
Dependent Claim
27 words
The invention of claim 5, further including temperature sensing means for determining the temperature of at least one of the food articles supported on said support means.
Claim 8
Dependent Claim
43 words
The invention of claim 6, further including second control means connected to said temperature sensing means and said drive means and said pump means to de-energize said drive means and said pump means when a desired temperature is sensed by said sensing means.
Claim 9
Dependent Claim
34 words
The invention of claim 2, wherein said control means can control to within ±2° F. the desired temperature to which the liquid cooking medium is to be heated and maintained by said heater means.
Claim 10
Dependent Claim
27 words
The invention of claim 8, further including temperature sensing means for determining the temperature of at least one of the food articles supported on said support means.
Claim 11
Dependent Claim
43 words
The invention of claim 9, further including second control means connected to said temperature sensing means and said drive means and said pump means to de-energize said drive means and said pump means when a desired temperature is sensed by said sensing means.
