Abstract
1,273,217. Reconstituting food. MINNESOTA MINING & MFG. CO. 18 June, 1969 [20 June, 1968; 26 Sept., 1968; 14 Nov., 1968; 4 Dec., 1968], No. 30927/69. Heading A2D. [Also in Divisions A4, H1, H2 and H5] Food is reconstituted by placing the food in casseroles each having an electric heating element associated therewith, placing the closed casseroles in a thermally insulated chamber which is maintained at refrigerated or freezing temperatures, energizing the heating elements at predetermined or intervals of time to heat the food in the casseroles whilst the chamber is maintained under the cooled conditions, deenergizing the heating elements in predetermined off intervals of time to allow the food to cool, and alternately repeating these steps throughout a total cooking time while the chamber is maintained under refrigerated or freezing temperatures. The process may be carried out in the apparatus shown in Fig. 1 wherein casseroles 33 are supported in trays 32 which are slidably positioned on shelves 25 to 29 of a rack 24. The rack is inserted into the chamber 11 which is provided with freezing coils 20. When the rack is fully inserted into the chamber, an electrical contact 30 mates with the plug 17 to supply electrical energy through wires 31 to magnetic connectors 50 which are embedded in electrically insulated rails 51 to 55 mounted below the shelves 25 to 29. The connectors 50 transmit the electrical energy through contacts 43 to a heating element 41 positioned in the casserole (Fig. 2). With reference to Fig. 2, the casserole 33 comprises a dish member 34 provided with an electrical heating element 41, a cover 46, and a layer of aluminium foil 48. To maintain the chamber 12 under refrigerated conditions, a refrigerant such as fluorinated hydrocarbons, ammonia or carbon dioxide may be delivered to the coils 20. Alternatively liquid nitrogen can be introduced into the cavity 13 to maintain a low temperature in the chamber.
