Abstract

Abstract An apparatus for cooking fruit and the like products includes a tank or cooking chamber disposed for receiving a quantity of such products and a quantity of water sufficient to cover the products therein and sufficient enough to create the necessary back pressure for a hydraulic head and sufficient enough to provide an adequate medium for agitation. Steam is supplied to the lower portion of the tank to raise the temperature of the water to a cooking temperature of the products submerged therein, which temperature may be the boiling point of water. Steam or moisture laden vapor which escapes to an upper surface of the body of water is recirculated under pressure to a lower portion of the tank, such that it will be redirected into the cooking area. Such recirculation is performed by a conduit and a blower or pump mounted in the path of the conduit. The conduit has an inlet above the level of the water in the tank and an outlet below the level of the water adjacent a bottom wall of the tank. The pump effectively increases the pressure of the steam and thereby increases its temperature. A method of cooking fruit and the like products includes submerging such products in a body of water, passing steam through the body of water until it is heated to the cooking temperature of the products, and recirculating under pressure the steam or moisture laden vapor which escapes from an upper surface of the body of water to a lower level thereof.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 153 words
Apparatus for cooking fruits and the like products in which said fruits are immersed in a body of water to form a slurry, said body of water being sufficient to cover said products to form said slurry and to create the necessary back pressure for an hydraulic head and of sufficient quantity to provide an adequate medium for the agitation of said slurry, said apparatus comprising: a. a closed tank disposed for receiving said slurry in a lower portion thereof, b. first means for introducing steam into the slurry contained in said tank for bringing said slurry approximately to a cooking temperature, c. recirculating means for recirculating under pressure any moisture laden vapor which escapes from an upper surface of the slurry to a lower portion of said tank and into the slurry for heating said slurry and for agitating said slurry, said recirculating means being separate and apart from said first means.
Claim 2
Dependent Claim 153 words
Apparatus for cooking fruits and the like products in which said fruits are immersed in a body of water to form a slurry, said body of water being sufficient to cover said products to form said slurry and to create the necessary back pressure for an hydraulic head and of sufficient quantity to provide an adequate medium for the agitation of said slurry, said apparatus comprising: a. a closed tank disposed for receiving said slurry in a lower portion thereof, b. first means for introducing steam into the slurry contained in said tank for bringing said slurry approximately to a cooking temperature, c. recirculating means for recirculating under pressure any moisture laden vapor which escapes from an upper surface of the slurry to a lower portion of said tank and into the slurry for heating said slurry and for agitating said slurry, said recirculating means being separate and apart from said first means.
Claim 3
Dependent Claim 62 words
The apparatus of claim 1, wherein said tank includes a confined space above the upper surface of the slurry contained therein; and said recirculating means includes a conduit extending from said space to a lower portion of said tank, and means for advancing moisture laden vapor under increased pressure through said conduit for increasing the temperature of the advancing moisture laden vapor.
Claim 4
Dependent Claim 19 words
The apparatus of claim 2, wherein said advancing means includes a pump mounted in the path of said conduit.
Claim 5
Dependent Claim 28 words
The apparatus of claim 3 and further comprising a check valve mounted in the path of said conduit between said pump and the lower portion of said tank.
Claim 6
Dependent Claim 59 words
The apparatus of claim 2, wherein said recirculating means includes a member mounted in the lower portion of said tank and having a plurality of apertures therein, said member being secured to the end of said conduit extending to the lower portion of said tank, such that moisture laden vapor will be introduced into said slurry at spaced locations.
Claim 7
Dependent Claim 46 words
The apparatus of claim 1, wherein said first means includes a conduit having a first valve for controlling the flow of steam therethrough, and a by-pass conduit having a second valve for controlling the flow of steam therethrough and connected in parallel with said first valve.
