Abstract
ABSTRACT OF THE DISCLOSURE
A utensil for preparing food in a microwave oven.
The utensil is provided with a ferritic-silicone coating upon a metal platter, which ferritic coating is covered by a silicone coating to prevent entry of air to the ferrite which would other-wise result in oxidation and degradation of the microwave heating properties of the ferrite. The metal platter rests upon and within a housing made of a material which is highly transmissive of microwaves and having a very low absorbence of microwave energy so that it remains cool. The housing services to insulate the platter electrically and thermally from its surroundings.

Description
~ .3~
Back~round of the Invention This invention rela-tes to a micxowave browning or searing utensil. Microwave ovens have become popular for cook-ing foo(l primarily ~ue to tlle ~,pecd and saonomy of operation resultiny from the microwav~ ~nt3rcJy heatinc3 the food ~roduct ~irectly. }~owever, since therc is no concen~ration o~ heat on the outer surface~ of the foo(l ~Jroduct, no l~rowniny or searing of the food product occurs. Many consumers consider the lack of browniny on food ~roducts a drawback. The appearance anq tast~ of microwave oven prepared food products ar~ dif~erent, and various at.tempts have been made to produce browned foods in microwave cookin~.
One means o~ producing browned foods has been to pro-vide utens.ils which will heat in a microwave environmen-t. The foocl surface in contact wi-th the heatad uten~il surface will become hot enou~h to bec~me cri~p and browned much as is the case in cookin.:3 with a ranye. Some of these are massive and re~uire a ~airly long time to heat such a~ microwave ab~orbing ceramics. Others such as xesistive Ellms may heat to higher thall de3ired temperatures and be subject to mechnical failure unles~ covered by another layer of gl~s~, ceramic or flimilar material. A film embedded iJl glass or cer~mic, of course, i8 fairly massive and slow to heat.
The apparatu~ disclo~ed in U.S. patent No. 3,941,967 to Sumi et al employs a ferri.te ceramlc or silicon carbide ceramic with added silicon dioxide or titanillm dloxide to lessen the electrical resi~tance o~ the ceramic to produce ~reater heating from the microwave eneryy in the microwav~ oven.
U.S. patent No. ~830,162 to Cop~on di~close~ cooking ves~els made of ferri-tes in the orm of alloya or ceramic~.
U.S. patent No. ~,266,103 to Rnderson e~ al di~closes u~ of ferrite adj~cent ~o a microwave re~lecting oernb~r and wherein the thickne~ of th~ ferri.-t.~ m~t~rlal may be ~ ct~d to producc a hea~ing elemen-t which will hea~ to a predetermined tempcrature which is a function oE ~he Curie temperatur~ of the ferrite. q`he ~nder~on paten~ x~lor~) to ~ri~, a materi~l u~ed in ceram.ics and refer~ ~lire~t.Ly ~o ceramic matcri~lla~

Summary of the Invention The present invention relates to brownin~ u~en6ils made to operate ~y mean~ of micr~wave .radiation within tha cavity of a microwave ovenO Specifically, I have been succe~-ful in pxoviding a microwave brcwniny uten~il which may be u~e~l ~aEely and ea~ily in a microwave oven.
An object of the present invention is to provide a microwave browning utensil which will heat in a microwave envixonment to produce browning or ~earing of a food product.
Another object of the present lnv~ntion i~ to provide a microwave browning utensil which is relatively slmple in de3ign and construction.
Still another object of the pre~ent invention Is to provide a microwave browning uten~il which is inexpen~ive to manufacture.
~3--Yet another object of the pre~ent invention is to provi~e a microwave browning utensil which employs a h ating elemont of a ferrite powder ~n an or~anic m~trix or a ~ilicone mutxix~

element which i~ rot~cl:ed fron~ oxidation and d~gx~ldal.lon.
With these and other objxcts in view the invention broadl~ compriqe~ a mic.rowav~ browniny uten3il having ~ micro-wave txansnlissive outer housin~ beneath and around a metal platter th~ lower surface of which is coated with a l~yer o Eerrite i.n a 9il icone sllatrix.

U~on the bottom ~-3urL~ce o~ metal platter 30 i~ thu h~aL-ing element 40. ~leating element ~0 is formed of a mixture ~1 of powdered ferri-tic mate.l:ial. held in a matrix o~ organic high mole~u-lar wei~ht material, preferably sili~one. Ferritic material as used he.rein including the claims shall mean magnetic iron oxide c~r any ferromagnetic material. Mixture 41 is extremely ~lcky and is self-adhesive to metal plat~er 30. Upon the surface of mixture 41 not in contact with metal platter 30, a layer 42 of organic high molecular weight ~aterial, prefexably ~ilicone., i~ add~d.
Layer 42 of silicone or other material overlaps past the edges of mix-ture 41 and onto the ~urrounding portion o metal platter 30 so -t.hat mixture 41 1~ ~ealed off f.rom the atmosphere at -the top by me-tal platter 30 and at the bottom by layer 42 of silicone. l'he layer 42 of silicone forms a barri.er which prevents entry of oxygen and moisture from the atmosphere into mixture 41. This is advantageous in this application because it allows use of ferritic materials which would, especially at elevated operating temperatures, react with atmospheric oxygen and moisture in a reaction which would destroy their desirable magnetic and micro-wave heating properties, were it not for the silicone layer 42 barriers. This allows use of relatively inexpensive ferritic materials. An example of a suitable material for use as the ferritic component of the ferritic-silicone mixture ~1 is Fe304 powder from naturally occurring magnetite as supplied by Indiana General of Valparaiso, Indiana, a division of Elec-tronic Memories and Magnetics Corporations~
The geometry of metal platter 30 and housing 20 are important to the functioning of the browning utensil 10. Metal platter 30 is shown in Fig. 3 with an annular groove 31 su.r-rounded by an upright vertical lip 32 which is in turn surrounded by a horizontal flange 33 all formed into metal platter 30.
Side wall 21 of housing 20 is shown vertical and surrounding vertical lip 32 of metal platter 30. Side wall 21 of housing 20 should be spaced approximately one-quarter inch away from upright vertical lip 32 of metal platter 30, with spacing of two-tenths -to three-tenths of an inch giving good results. Such a spacing results in enhanced heating of heat element 40 by the microwave energy within the microwave oven.
In addition, the metal platter 30 should be spaced approximately three-quarters inch from the floor of the microwave ~ ,;
