A thermally insulated cooking pot consists of an outer pot and an inner pot. The inner pot is suspended within the outer pot by hanging from the top inner circumferential area of the outer pot with its own top outer circumferential area. The space between the inner and outer pots becomes an insulation cavity. The contact point between the two pots is sealed by a pliable packing ring with an L-shaped cross-section, thereby sealing the insulation cavity. This sealed insulation cavity provides excellent thermal insulation. The packing ring contains a plurality of protrusions on the surface that come into contact with the inner pot to prevent the packing ring from sticking to the inner pot. The gap formed between the packing ring protrusions and the inner pot prevents the inner pot from sticking to the packing ring.

Food serving pans made from a heat conductive materials include a gasket protecting a flange to protect fingers from heat or cold, improve gripping ability, seal against countertops of food serving tables, and protect paint or nonstick coating from chipping off the flange. The food serving pan is made from aluminum or other highly heat conductive material. The gasket comprises silicone, other elastomer, or other heat resistant and insulating material. The gasket includes a circumferential sealing ridge and finger gripping recess. A food serving system includes one or more food pans and food serving table. The food serving pans help maintain food at a desired temperature by efficiently transferring heat or cold from the serving table while sealing the interface between the flange and the countertop of the serving table. The interface between the gasket and flange prevents buildup of food or debris, maintaining cleanliness during repeated use and cleaning cycles.

The food serving pan is made from aluminum or other highly heat conductive material. The gasket comprises silicone, other elastomer, or other heat resistant and insulating material. The gasket includes a circumferential sealing ridge and a finger gripping recess. A food serving system includes one or more food pans and a food serving table. The food serving pans help maintain food contained therein at a desired temperature by efficiently transferring heat or cold from the serving table while sealing the interface between the flange and the counter top of the serving table. The interface between the gasket and flange prevents build up of food or debris, thus maintaining cleanliness during repeated use and cleaning cycles.

A fuel-fired water heater has a single pass condensing-type heat exchanger disposed within its water storage tank portion. The heat exchanger includes a primary non-condensing portion defined by a combustion chamber positioned in an upper interior portion of the tank and having a spaced series of vertical tubes depending therefrom. A secondary condensing portion of the heat exchanger is defined by a plenum having a top side connected to the bottom ends of the vertical tubes, and a bottom side from which a downwardly coiled flue tube depends. A fuel burner generates hot combustion gases that are sequentially flowed into the combustion chamber and then downwardly through the balance of the heat exchanger in a single pass.

A cooking double boiler including an outer pan that is heated upon pouring water therein, an upper lid that covers an upper aperture thereof, and an inner pan with a flange that is set into the interior of the outer pan. The outer pan includes a peripheral edge portion that supports the flange of the inner pan, wherein a plurality of concave portions for directing generated water vapor upward of the inner pan are located at the peripheral edge portion. The cooking double boiler has vapor spouts located between the peripheral edge portion of the outer pan and the flange of the inner pan for movement between open and closed positions.

A sacrificial anode assembly operative to inhibit corrosion in the metal tank portion of a water heater includes a cylindrical metal anode member having an end retained within a tubular, electrically non-conductive plastic insulating sleeve which, in turn, is captives retained within a metal cap portion of the assembly. A resistor is received in an end surface groove of the sleeve and has a lead wire spot-welded or soldered to a core wire portion of the anode member. To prevent contact between the lead wire and the metal cap, and to protect the lead wire against vibration caused breakage at its spot weld or solder area, a U-shaped central portion of the lead wire is received in a through-opening in the resistor-supporting end of the sleeve which is covered by an annular insulating wafer formed from an electrically non-conductive material.

A frying vessel having heating elements placed within a cylindrical sleeve so as to direct a current of heated frying fat.

The efficiencies of illustrative embodiments of vertical center flue type fuel-fired base water heaters are improved by installing in the water heaters variously configured tubular condensing type secondary heat exchangers of smaller diameters than the associated center flues. The efficiency increases are achieved with components and manufacturing processes similar to those utilized in the base water heaters and secondary heat exchanger materials similar to those in the tank portions of the base water heaters.

A frypot having a corrugated bottom portion. The corrugations project into an interior volume of the frypot, so that there are troughs disposed between the corrugations. During operation of the frypot, oil located in these troughs remains cooler, thus prolonging the life of the oil.

A system for heating water which is primarily used for swimming pools, spas or other recreational purposes comprising a heater assembly having a heating element mounted within a housing in heat exchanging relation to water passing there through, wherein the heating element is formed of a titanium material and is structurally configured to maximize heat exchange by incorporating a substantially twisted orientation of the heating element relative to a central longitudinal axis thereof. The system further contemplates the heating element containing heat exchange fluid passing there through, wherein the heating element is remotely spaced from a compressor assembly which processes the heat exchange fluid to accomplish a rise in temperature of the water being heated. Additional embodiments include a filter assembly of cooperative dimension disposed in predetermined relation to the heating element within a common housing for concurrent filtering and heating of the water passing there through, wherein the heating element and the filter assembly may be disposed in a substantially combined operative orientation or alternatively, spaced apart in an at least partially segregated relation but within the same housing.

The present invention relates to a temperature control device comprising a control unit for controlling a heating unit of a food cooking device according to the following control scheme: i) a preheating period for heating up the food to a first food temperature of at most 60 DEG C; ii) a temperature holding period for holding the food temperature within a temperature range of 30 DEG C to 70 DEG Cfor at least one minute; and iii) a heating period for heating up the food to a second food temperature of at most 100 DEG C. This control scheme ensures that gamma-glutamyl hydrolase is not thermallyinactivated and thus can hydrolyze poly-glutamate forms of folate into mono-glutamate forms and that folate bioavailability during cooking processes is enhanced.

Food serving pans made from heat conductive materials include a gasket positioned over a flange to protect fingers from heat or cold, improve gripping ability, seal against countertops of food serving tables, and / or protect paint or non stick coating from chipping off the flange. The food pan is made from aluminum or other highly heat conductive material. The gasket comprises silicone or other heat resistant and insulating elastomer.
