Microwave oven drying of artificial stone

The Journal of Prosthetic Dentistry, 1985
The 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

2006
The 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 ...

Microwave Drying of Solids

Journal of Microwave Power, 1967
AbstractThe application of high power microwaves to the removal of moisture from solids, though far from an new concept, has until recently been impractical due to lack of suitable microwave generation equipment. From the number of power microwave systems now in operation, it is apparent that this is no longer a serious problem.Follow inga brief ...

Microwave drying kinetics of a clay-plate

Ceramics International, 1995
This study presents the development of an exponential model for the description of kinetics in the drying process of a porous material under the condition of dielectric heating. The model describes the changes in moisture content and in the rate of drying related to the duration of the process, as well as the moisture content in the material to be ...

Preparation of dry honey by microwave–vacuum drying

Journal of Food Engineering, 2008
Abstract 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 ...

Microwave drying effects on dichromated gelatin holograms

Applied Optics, 1989
Exposing dichromated gelatin holograms to microwave radiation considerably increases their resistance to heating, either for wide or narrowband holograms. No wavelength shift was observed for the former and only a small shift was observed for the latter.

Microwave Drying of Clothes

Journal of Microwave Power and Electromagnetic Energy, 1991
This paper presents experimental results using a conventional electric clothes dryer that was modified to heat clothes by microwave power. Furthermore, the exhaust air was dehumidified and its thermal energy was partly recovered and recycled to the heater intake of the dryer.

Comparison of drying characteristic and uniformity of banana cubes dried by pulse‐spouted microwave vacuum drying, freeze drying and microwave freeze drying

Journal of the Science of Food and Agriculture, 2014
AbstractBACKGROUNDTo overcome the flaws of high energy consumption of freeze drying (FD) and the non‐uniform drying of microwave freeze drying (MFD), pulse‐spouted microwave vacuum drying (PSMVD) was developed.RESULTSThe results showed that the drying time can be dramatically shortened if microwave was used as the heating source.

Moisture Determination by Microwave Drying

Transactions of the ASAE, 1983
ABSTRACT A study was conducted to evaluate the use and accuracy of a household microwave oven for quick moisture determination of sorghum leaves, wheat, soybeans and rough rice. Standards used for comparison were ASAE procedures for forages, wheat, beans (edible); and AOAC procedure for rough rice.

Microwave drying characteristics of spinach

Journal of Food Engineering, 2007
Abstract Spinach leaves ( Spinacia oleracea L. cv. “Meridian”) with 50 g weight and 9.01 humidity on dry basis were dried in microwave oven using eight different microwave power levels ranging between 90 and 1000 W, until the humidity fell down to 0.1 on dry basis.
