Microwave classification

Commercial dryers differ fundamentally by the methods of heat transfer employed (see classification of diyers, Fig. 12-45). These industrial-diyer operations may utihze heat transfer by convection, conduction, radiation, or a combination of these. In each case, however, heat must flow to the outer surface and then into the interior of the solid. The single exception is dielectric and microwave diying, in which high-frequency electricity generates heat internally and produces a high temperature within the material and on its surface.

Through analysis of these classification maps for each pentad it is possible to define specific dates of ice events for the water body or its sub-regions. In some cases the definition of ice event dates could be tmcertain due to (a) data gaps, (b) ambiguous ice detection related to land contamination of the microwave signal, and... 

Clearly, these classifications are also useful for reactions under the action of microwave irradiation [6]. From the engineering perspective, the principal distinctions are drawn between homogeneous and heterogeneous liquid and/or gas-phase... 

Nonetheless, microwave-assisted solvent-free conditions have wide applications in industrial processes and enable classification of microwave chemistry as an environmentally benign method, or green chemistry [3e-g, 28, 32).

Moisture content analysis by oven drying (both conventional and microwave) is included in compaction, classification and consolidation.
