Microwave and microwave-vacuum drying as alternatives to convective drying in barley malt processing
Innovative Food Science and Emerging Technologies, 2021Abstract Barley malt is widely used in food and beverage industries. Although microwave drying can be an interesting alternative for stabilization, it has been traditionally processed by convective drying. This work studied the microwave and microwave-vacuum drying of barley malt, evaluating hydration, germination and drying.

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.

Microwave Drying Kinetics of Okra
Drying Technology, 2007In this work, the effects of power level and sample mass on moisture content, moisture ratio, drying rate, and drying time of Turkey okra (Hibiscus esculenta L.) were investigated using microwave drying technique. Various microwave power levels ranging from to 180 to 900 W were used for drying of 100 g of okra.

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.
