Finger millet (Eluesine coracana) and foxtail millet (Setaria italica), are highly nutritious minor millets and hence is used in most of the staple foods. The present study was to estimate the thin layer drying characteristics of foxtail and finger millet and developing a thin layer model which adequately fits the data. Foxtail and finger millet with an initial moisture content of 0.314 and 0.3...

The effects of slice thickness, microwave pre-treatment, and drying temperature on drying orange kumara slices were investigated. The highest drying rate, with minimal loss of colour, occurred at 80°C. Slice thickness did not significantly influence colour but drying time increased with slice thickness. The drying curves fitted the Page thin-layer drying model. Two minutes microwave pre-treatme...

A new semi-theoretical thin-layer model of the fluidized bed drying of Echium amoenum Fisch. & C.A. Mey. petals has been developed. Experiments were conducted under different conditions: temperatures of 40, 50 and 60 °C, and air velocities of 0.5, 0.75 and 1.0 m/s, until the moisture content decreased to 0.04.-0.06 kg of water per kg of dry matter. Drying processes in the fluidized bed were com...

thin layer drying of russian olive (elaeagnusan gastifolial l.) fruit using a hot air dryer in order to calculate effective moisture diffusivity, activation energy and energy consumption has been evaluated in this article. the selected variables included three levels of air velocity of 0.5, 1 and 1.5 m/s and three air temperature levels of 50, 60 and 70°c. increased air temperature increased ef...

Calcium carbonate is a versatile mineral with diverse industrial applications. Drying is a necessary processing step in preparation of calcium carbonate product. Deep knowledge of drying kinetics is required in order to design an appropriate dryer. The main aim of the present study was to investigate the drying kinetics of calcium carbonate, experimentally. Thirteen empirical correlations with ...
