摘要:
A countertop deck oven has advanced conduction elements to cook according to an optimum thermal spectral profile of a selected food by selectively using an etched foil heating element and a secondary heating technology element both disposed within the baking chamber. A controller independently controls the etched foil heating element and the secondary heating technology element according to a selected thermal profile having different levels of heating assigned to each of the heating elements. Thereby the oven heats a particular food in the baking chamber according to its associated spectral heating requirement.

A furnace system for thermal processing of products and materials is disclosed which is particularly useful in processing touch screens for computer tablets and silicon wafers employed in fabricating solar cells. The system employs a hybrid of microwave and radiant heating of workpieces to provide controlled heating of the workpieces. A plurality of susceptors are disposed a furnace chamber. A plurality of microwave sources are arranged to provide microwave radiation in the chamber to uniformly heat workpieces in the chamber and to provide uniform heating of the susceptors. The susceptors are effective upon microwave heating by the microwave sources to provide uniform radiant heating of the workpieces in the chamber.

A system and process for rapid and uniform curing of grinding wheels (2) to obtain grinding wheels (2) with better durability, at 180-220 °C deploying microwave energy at 800-5000 MHz in which closely fitting green wheel sample holders (1) are made of carbon bearing microwave susceptor materials such as graphite, silicon carbide with tiny holes on the surface. These sample holders (1) help in maintaining the shape and geometry of the final wheels (2) after curing and reduce energy consumption. The performance of the grinding wheels (2) cured by this process is better than those cured by presently used process employing steel plate sample holders of the present state-of-art.

The present invention relates to a fermenter, a microwave oven including the fermenter, and a method of controlling the fermenter and microwave oven. The fermenter of the present invention comprises a fermenter casing having one open side and defining a fermenting chamber; a fermenter door for selectively opening or closing the fermenting chamber; a thermoelectric element for applying heat to the fermenting chamber or absorbing heat from the fermenting chamber; and a current switching device for converting current supplied to the thermoelectric element such that the thermoelectric element can absorb or generate heat. According to the present invention, the fermenter can be very conveniently employed and a microwave oven with various functions can also be provided.
摘要:
High volumetric, steady state flow rates of metal compositions can be rapidly melted, or otherwise heated to a desired degree, by conveying the metal composition (106) through the length of a microwave chamber (140) containing a microwave susceptor (150) in thermal contact with the flow. Microwave energy is propagated in the cavity to heat the microwave susceptor. The resultant thermal energy is then transferred to the metal composition. Because metal compositions tend to be excellent heat conductors, the transfer of thermal energy from the susceptor throughout the volume of the metal composition occurs quickly. Indeed, enough thermal energy can be generated to easily melt nonferrous metal alloys in connection with steady state die casting operations. Microwave melting would occur so rapidly, that significant reductions in cycle time would be achieved. Additionally, the use of microwave energy for melting is economically advantageous, because microwave heating is extremely energy efficient.

Systems and/or techniques for preferentially directing electromagnetic energy towards colder regions of an object are provided. During at least a portion of a heat treatment via a microwave oven, temperature measurements of the object are acquired to identify colder regions of the object. Microwaves ovens often heat objects non-uniformly. For example, an outer surface of a burrito may be hot-to-touch while a center core of the burrito is still frozen.

The present invention relates to a heat-treatment-device for protein containing products, which are transported by a transportation means through the device and past at least one microwave radiometer antenna, wherein the microwave radiometer (1) is located within a shielding means (6) which extends at least partially around the cross section of the transportation means (5) and isolates at least partially the microwave radiometer antenna (2) from external sources of electromagnetic radiation.
摘要:
After an initial temperature (T0) of a heating chamber is detected (S34), heating by microwave is effected until an output from a humidity sensor rises by 1.0 V which indicates a predetermined amount of humidity change (S35-S39). Then an additional time is calculated from the initial temperature (T0) and a time required to rise by 1.0 V (S40 to S42, S50). During the additional time, heating by microwave is effected (S43, S51), and then heating by a heater is effected. As a result, steam of food is allowed to evaporate, so that food is finished in a crisp condition. Consequently, it is possible to deliciously defrost and heat a cooked frozen food.
