For coal-fired power plants information of the moisture content in the coal is important to determine and control the dynamical behavior of the power plants. E.g. a high moisture content in the coal can result in a decreased maximum load gradient of the plant. In this paper a method for estimating the moisture content of the coal is proposed based on a simple dynamic energy model of a coal mill...

Real-time non-invasive moisture content sensing techniques are needed for online moisture measurement and control in food products. In this investigation, a dielectric spectroscopy based system is used for moisture determination in cookie dough. Experiments were conducted with a concentric ring dielectric sensor in the frequency range from 10 Hz to 10 kHz. The system is calibrated based on a li...

A technique is described for estimating moisture content of small samples of hard red winter wheat (10 to 30 kernels) by impedance measurements at 1 and 4.5 MHz on a parallel-plate capacitor holding the sample between the plates. The measurement system was calibrated by measurements on samples, ranging from 9 to 20% moisture content, wet basis, from three wheat cultivars grown in 1991 and 1992,...

water desorption isotherms of raw and osmotically dehydrated (at 25ºc, for 2 hours, with 10 and 26% nacl solutions) garlic slices at different temperatures (25, 40, 55, and 70ºc) were experimentally determined over a range of water activity of 0.05–0.90 using a static gravimetric method. desorption isotherms can be classified as type iii. the water desorption isotherms of raw garlic clearly sho...

The study examined the effect of moisture content on maize shelling speed using a manually operated hand Sheller (cone type). Twenty (20) unthreshed maize cob samples (A-J) were used for the study. The samples were analysed in the laboratory for parameters such as weight of samples before and after drying, moisture content and shelling speed. The result indicated that sample J, after sixty nine...

the presented study shows a simple way for optimization of extrusion process, which was used for deterioration of cyanogenic glycosides – antinutritive components of linseed, with minimum damage of essential alpha-linolenic acid (ala) at the same time. extrusion of the material was done on a laboratory single screw extruder. content of hydrogen cyanide (hcn) as a measurement of cyanogenic glyco...

In most studies, moisture sorption into amorphous foods is expressed as a change in the bulk moisture content, which does not provide detail on how a moisture front moves into the food. This study was targeted towards characterization of the moisture behavior in amorphous saccharide materials of different molecular weight (MW), glass transition temperature (Tg) and moisture content. Various sug...

An NMR imaging technique published in literature was adapted to investigate the role of glass transition on Fickian and non-Fickian modes of moisture transport in pasta. The modified technique allowed measuring the moisture distribution in samples with initial moisture content from 10% to 50% or higher. A change in slope in the signal intensity versus moisture content curves indicated different...
