The effect of different air temperatures (40, 50, 60 and 70°C), air velocities (1 and 2 m/s) and bed depth (monolayer, 3 and 5 cm) on drying kinetics and lipid quality (peroxide value and free fatty acids) of a variety of Persian Pistachio nuts (Abasali variety) were studied. Additionally, effective diffusivity (D ) was determined eff by using Fick’s second law varied from 7.061×10 to 2.105×10 ...

We present the results from a small-angle X-ray scattering (SAXS) study of lateral drying in thin films. The films, initially 10 μm thick, are cast by dip-coating a mica sheet in an aqueous silica dispersion (particle radius 8 nm, volume fraction ϕ(s) = 0.14). During evaporation, a drying front sweeps across the film. An X-ray beam is focused on a selected spot of the film, and SAXS patterns ar...

Open sun drying (OSD) is the most common method of crop drying in developing countries. Despite several disadvantages, it is widely practiced because it is a simple way of drying. Crop temperature, temperature around the crop, solair temperature, and rate of moisture evaporation are the important parameters in OSD. The thermal behavior of OSD of green chillies, green pea, white gram (kabuli cha...

This article presents an investigation of the potential of spray and spouted bed technology for the production of dried extracts of Rosmarinus officinalis Linné, popularly known as rosemary. The extractive solution was characterized by loss on drying, extractable matter and total phenolic and flavonoid compounds (chemical markers). The product was characterized by determination of loss on dryin...

Moringa oleifera leaves have been dried in a tray drier to investigate the drying behaviors of at three different temperatures for their moisture content, color, iron and protein as well total phenolic content. Three levels were chosen varying from 50, 60 70 °C this study. Drying time reduced significantly with rise temperature. The final content was 4.89, 4.79, 4.59 % reached equilibrium 4, 2,...
