Definitions
- the foodstuff and the source for emitting the infrared rays are placed in a region [56] References Cit d where electromagnetic waves are radiated from a high frequency generator.
- crystalllzed glass having fine 35397 W970 Levinsonm 219M055 pieces of carbon fibres scattered throughout may form 3.585.258 6/1971 Levinson 219 10.55 the infrared source.
- a 3.662.141 5/1972 Schauer, Jr. 219/10.55 layer of silicon carbide may be formed on an insulat- .9 89 93 Jone 3 UX ing base plate.
- the infra- 5 9 6951 Under l r 219/543 red heat is generated by the action of the electromag- 2.546.707 3/1951 Mocha 7/54 netic waves on the specially constructed source.
- the invention relates to an apparatus and method for browning the exterior surfaces of a foodstuff in an electronic range by providing an additional infrared heating of the foodstuff as a phenomena of heating of a dielectric through high frequency.
- V the'foodstuff may be done to the extent of scorching while the interior may remain in a state of half roasting. For example, a roast may be well done on the exterior while remaining rare in the interior.
- the cause of heating is due to molecular motion in the interior of the foodstuff when it is subjected to high frequency electromagnetic radiation.
- the foodstuff itself becomes a heat generating body and the interior and exterior thereof are cooked equally and swiftly.
- Another object of the invention is to provide a method and apparatus for heating the interior of the foodstuff sufficiently in a short time as well as simultaneously browning the exterior thereof.
- Another objectof the invention is to provide an infrared source generating body for use in an electronic range.
- the present invention provides an apparatus and method in which a source for emitting infrared radiation and a foodstuff to be heated are put in a region of propagation of electromagnetic waves emitted from a high frequency generator.
- the whole of the foodstuff to be heated is subjected to high frequency dielectric heating and at the same time, the exterior surface of the foodstuff is browned by the infrared radiation emitted from the infrared source.
- FIG. 1 diagrammatically illustrates the operation of the present invention
- FIG. 2 is a perspective view of an electronic range incorporating the present invention
- FIG. 3 is a perspective view illustrating an alternate embodiment of the heat generating source.
- FIG. I a conventional electronic range is illustrated in somewhat schematic form.
- a foodstuff l to be processed is placed in the heating chamber 4 of the range and is subjected to high frequency electromagnetic radiation (illustrated by the numeral 6) which is generated by a high frequency generator 9 (FIG. 2).
- the high frequency radiation 6 traverses the interior 4 of the range and acts upon the foodstuff 1 contained therein.
- molecular motion in the interior of the foodstuff causes heating and as a result the foodstuff itself becomes the heat-generating body.
- foodstuff prepared in this manner is quickly and rapidly cooked and the interior and exterior surfaces are generally cooked to about the same degree.
- a conductive thin film 3 may be formed on the surface of a dish or other vessel 2 in which the foodstuff is contained when placed in the oven.
- an insulating plate 5 having a similar conductive thin film 3 thereon may be provided at an appropriate position in the heating chamber 4 of the electronic range.
- an electronic vortex current is generated in the thin film 3 by the action of the electromagnetic waves 6 causing the thin film to heat and become an infrared heat source. Accordingly, the infrared radiation from the thin film 3 located on the dish 2 or on the insulating plate 5 radiates infrared radiation to thereby apply additional heat to the exterior surfaces of the foodstuff l at the same time the interior of the foodstuff is heated by the passage of the high frequency electromagnetic waves therethrough.
- the conductive thin film 3 may be formed on the surface of the dish 2 or on the insulating plate 5.
- a material such as glass having a low coefficient of expansion and heat resisting properties.
- a thin tin oxide coating is glazed at a high temperature to the surfaces of the dish thereby providing a conductive thin film on its surfaces.
- a similar thin film layer of tin oxide may be provided on an insulating plate 5 at an appropriate location within the range. If the thickness of the layer 3 is about 0.5 p. the approximate resistance of the dish 2 or the insulating plate 5 will be on the order of 1.5 X l0- 0cm. As a contrast, for example, the resistance value for copper is 1.7 X 10 Gem and, for nichrome, 1.1 X 10 0 cm.
- a conductive glass 3 constructed as above exhibits excellent performance when utilized as an infrared heat generating source in an electronic range. This is due to the combined effect of the electrical insulating properties of the glass itself and the electrical conducting properties of the coated film. If the region of wavelength is in the neighborhood of the maximum emissivity of infrared radiation is made to lie somewhere at more than 3 p. there is little change in the heating effect as the surface color of the object varies during cooking. Also, the efficiency of heat transfer radiation is high.
- a conductive thin film 3 on the dish itself no modifications are necessary to the range.
- the foodstuff is simply placed in the dish and the range is operated in a conventional manner.
- the coating on the glass may be transparent or attractively colored.
- the dish may also be utilized as a convenient serving dish.
- an infrared heat generator is supplied without the necessity of a separate electrical power source within the range.
- the insulating plate may be arranged in the range in any convenient manner so that it may be removed if desired. In either case, a separate power source is not required as the thin film conductive layer 3 provides the infrared heat source as the electromagnetic waves act upon it.
- the principal materials Si O Alggg l iz o, etc.
- agents for nucleus formation Zr 0 Ti 0 etc.
- the mixture is then fused at a high temperature of about l,600C and, processed by molding it to the required shape and dimension.
- the molded shape is then annealed to remove stresses.
- the raw material at this stage of process remains amorphous and the finished product is obtained by giving primary heating (700800C) continuously in an oven for crystallization to keep the original form of the raw glass.
- the glass is then subjected to a secondary heating treatment (800900C).
- the above primary and secondary heat treatments are the heating schedule based on the theory of generation and growth of crystals.
- small nuclei having dimensions of from several ten to several hundred of A are generated, then after the elevation of the temperature amorphous regions are formed around the nuclei.
- the above amorphous regions change to B-Eucryptite (Li2O.Al2 O 2 SiO;) and M,o and to microcrystals of solid solution of SiO
- the crystalline particles are less than 0.01 -0.5 [.L, of smaller dimension than the wavelengths of visible rays and the index of refraction of light is the same as that of the glass.
- the transparent products are thereby obtained. If semi-transparent or white objects are desired further heating process may be applied.
- the glass obtained by the above process is to be defined as a crystallized glass".
- a conductive glass as shown in FIG. 3 may be provided. Fine pieces of carbon fibre 11 are sprinkled and adhered to a dish formed of electrically insulating and heat-resisting glass, ceramic or the like.
- the above carbon fibre I l is a popular name for fibres of cellulose or acryl baked (carbonized) at a temperature exceeding 1,000C on immersing them in nitrogen or alchol by isolating from oxygen-
- a layer of silicon carbide (SiC) may be formed as the thin film 3 on a dish using heat resisting glass or ceramic as the principal body. Because of its high melting point this embodiment operates satisfactorily in a high temperature environment.
