Geotechnical Testing Journal, 1990
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 ...

Grass and Forage Science, 1968
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.

Journal of Microwave Power, 1972
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 ...

Microwave Drying Characteristics of Parsley
Biosystems Engineering, 2004Parsley (Petroslinum crispum Mill.) leaves were dried in a domestic microwave oven to determine the effects of microwave output power on drying time, drying rate and the dried product quality in terms of colour. Seven different microwave output powers ranging from 360 to 900 W were used in the drying experiments.

Journal of Microwave Power, 1984
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.

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 oven drying of artificial stone
The Journal of Prosthetic Dentistry, 1985The compressive strength of various artificial stones were tested using air, oven, and microwave oven drying methods to compare the three for drying refractory casts. The microwave oven can be used for rapid drying of refractory casts in removable partial denture construction. However, it should not be used for drying extremely wet casts.

Microwave and Dielectric Drying
2006The unique heating mechanisms of microwaves and dielectrics permit dramatic energy savings in many instances, as well as providing other benefits. Thermal conductivity often plays a lesser role in microwave and dielectric heating than in conventional heating because of the great speed with which the former heat thus reducing the time in which thermal ...
