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.

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 ...

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 ...

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.

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, 1995This 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 ...

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.

The effect of microwave drying pretreatment on dry torrefaction of agricultural biomasses
Bioresource Technology, 2019This paper examines the effect of microwave drying on biomass characteristics and subsequent dry pyrolysis and characteristics of produced biochar from rice straw, sugarcane bagasse, rice husk and cotton stalk compared to oven drying at 105 °C. Dried samples from both methods are torrefied at 250 and 300 °C with 30-minutes residence time.
