Benefits of technology

[0008]An embodiment of the invention may comprise a microwave heating system comprising: a non-modal interplate microwave applicator configured to receive a load to be heated by microwaves radiated from the applicator; a microwave source connected to the non-modal interplate microwave applicator; a nonresonant enclosure that at least partially encloses the non-modal interplate microwave applicator; and a supporting structure in combination with the non-modal interplate microwave applicator for maintaining the load within the non-modal interplate microwave applicator.

Problems solved by technology

However, such devices have inherent disadvantages and limitations which may include: uneven specimen heating due to the variation of microwave energy density within the mode patterns, bulkiness due in part to the requirement for a resonant cavity, complexity in order to control or compensate for variation in energy density with the field to be heated, imprecision, unsuitability for processing single specimens or small groups of specimen, troublesome constraints on specimen orientation and placement, power and voltage requirements, excess heat generation, requirement to use a fixed microwave frequency, and high cost.

Embodiment Construction

[0056]The various embodiments of the invention presented herein illustrate how to practice the invention and the various advantages the invention has over existing methods.

[0057]By directly heating a load using a non-modal interplate microwave applicator as described herein or equivalent variations thereof, a number of beneficial effects may be achieved including that the non-modal interplate microwave applicator may be made very small, it may require only a very low power while providing uniform, well-controlled heating of loads positioned between the plates; the non-modal interplate microwave applicator may be formed automatically by bringing the plates together automatically which enables a load to be inserted in or removed from between the plates of the applicator; the non-modal interplate microwave applicator may be built into load holders that move from station to station; independent applicators for a plurality of loads may be grouped together in a compact manner to heat tray...

Abstract

Disclosed is a microwave heater and a method of heating. The microwave heater includes a non-modal interplate microwave applicator and may include a nonresonant enclosure. The non-modal interplate microwave applicator is configured to receive therein a load to be heated by microwaves radiated from the non-modal interplate microwave applicator.

Description

PRIORITY CLAIM[0001]The present application claims the benefit of copending Provisional U.S. Patent Application 61 / 286,917, entitled “NON-MODAL INTERPLATE MICROWAVE HEATING SYSTEM AND METHOD OF HEATING,” filed Dec. 16, 2009, and incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present disclosure relates to microwave heating systems and, more particularly, to microwave applicators for heating diagnostic tissue specimens and reagents and methods of heating specimens.BACKGROUND OF THE INVENTION[0003]A microwave applicator employs microwave radiation to heat an object. Microwave applicators may be used in many different applications ranging from home or personal use for heating foods, to commercial or industrial uses.[0004]Efforts have been made to adapt microwave ovens designed for domestic kitchen use for use in laboratory specimen and reagent heating. Multi-mode microwave systems including those designed for domestic use and commercial laboratory use e...
