Abstract Drying of soil specimens in microwave ovens can permit rapid determination of moisture content; such determination is very important in field quality control of earthwork construction. A laboratory study was performed to investigate differences between soil moisture contents based on microwave oven drying and moisture contents ...

AbstractA method for drying of leather is proposed where emphasis is placed on the uniform power distribution along the surface to achieve uniform drying and a high quality of finished product. Laboratory results indicate that the method is feasible at a lower energy cost and time saving, when compared to conventional methods, without any sacrifice in ...

The results on microwave drying of a bamboo species, Dendrocalamus stocksii, are presented in this paper. Bamboo specimens were dried in a continuous belt microwave dryer at varying microwave power ranging from 400 to 1600 Watt for different time periods, and moisture loss was determined. Microwave drying rates were compared with kiln drying rates. The

Microwave heating has recently been suggested as a method of drying herbage. A slightly modified commercial microwave cooking‐oven has been tested for this purpose and was found to dry 400 g of fresh herbage in 15‐20 min. The water‐soluble‐carbohydrate contents of herbage samples dried (a) by microwaves and (b) by freezing were similar.

Microwave permittivity of dry sand
IEEE Transactions on Geoscience and Remote Sensing, 1998The relative dielectric constant, or relative permittivity, /spl epsiv/ of dry snow, is independent of frequency from about 1 MHz up to the microwave range of at least 10 GHz. New measurements of with improved accuracy were made with a specially designed resonator operating near 1 GHz.

AbstractThe technical feasibility of using microwaves to dry various types of commercial polymers was investigated in batch-mode experiments with a 1-k W microwave generator/cavity. The polymers tested were polypropylene, low-density polyethylene, hydroxyelhyl cellulose, polyisoprene rubber, and vinyl chloride/vinyl acetate copolymer.

Preparation of dry honey by microwave–vacuum drying
Journal of Food Engineering, 2008Abstract Microwave–vacuum (MWV) drying was investigated as a potential method for obtaining high-quality dried honey. Liquid honey was heated and dehydrated in a MWV dryer to a moisture content less than 2.5% within about 10 min. The drying curves and the temperature changes of samples were tested during MWV drying at a different of microwave power ...
