Intermittent microwave drying improves the quality of dehydrated product, because reduces effect hot spots. Mathematical modelling is essential to understand physics this process and optimize operation conditions. However, there are few studies about intermittent drying. This work proposed a mathematical model based on mass balances liquid vapor water in which non-equilibrium formulation descri...

This method for determining aluminum in human serum involves electrothermal atomic absorption spectrophotometry. A longer drying time allows less pre-dilution of the sample, and the method also includes a flush cycle after atomization. Standard-addition methodology is used to eliminate matrix effects and the need for a standard curve. We used this method on serum from 50 normal persons and from...

BACKGROUND A reliable measurement of brain water content (wet-to-dry ratio) is an important prerequisite for conducting research on mechanisms of brain edema formation. The conventionally used oven-drying method suffers from several limitations, especially in small samples. A technically demanding and time-consuming alternative is freeze-drying. NEW METHOD Centrifugal vacuum concentrators (e....

Characteristics of microwave drying of wood strands with different initial moisture contents and geometries were investigated using a commercial 10 small microwave oven under different power inputs. Temperature and moisture changes along with the drying efficiency were examined at different drying scenar­ ios. Extractives were analyzed using gas chromatography=mass spectrometry (GC=MS). The res...

Microwave (MW) drying is a rapid dehydration technique that can be applied to specific foods. Increasing concerns over product quality and production costs have motivated the researchers to investigate and the industry to adopt microwave drying technology. The advantages of microwave drying include the following: shorter drying time, improved product quality, and flexibility in producing a wide...
