drying behavior of two types of pomegranates as well as the effect of drying conditions on moisture loss trend and on effective diffusion coefficient of arils are discussed in this article. also, an appropriate mathematical drying model as well as the activation energy of sweet and sour pomegranate arils, dried in vacuum and microwave driers are pursued and presented. results of regression anal...

dehydration, as one of the practical ways to increase the shelf-life and applicability of yoghurt in various foodstuffs, is normally done by freeze drier (fd) which is an expensive and time-consuming process. for these reasons, in the present study the capability of microwave–vacuum drier (mvd), as an alternative process, was investigated. for doing so, the fat free yoghurt samples of 2.2, 4.2 ...

Experiments were conducted on dry untreated onion shreds (2 mm thickness) or treated with salt (5% solution) and potassium metabisulphite (0.5% solution) in convective drier at 50 °C ((46±4) % relative humidity (RH)), 55 °C ((35±4) % RH), 60 °C ((28±4) % RH) and 65 °C ((20±4) % RH), heat pump-assisted convective drier at 35 °C ((32±2) % RH), 40 °C ((26±2) % RH), 45 °C ((19±2) % RH) and 50 °C ((...

Drying of the soymilk residue Okara was investigated by the two different drying processes in order to obtain good quality Okara in respect of its composition and shelf life characteristics. In one method the drying of wet Okara was accomplished in a Vacuum tray drier, maintained at around 758 mm Hg and 50 o C thereby reducing moisture content by as much as 95%. In the other method drying of Ok...

A study was conducted to find out the optimum tray load and drier type for the drying of osmosed mango, guava slices and aonla segments. The osmosed slices and segments were dehydrated in a cabinet drier, low temperature drier and vacuum drier with the tray loads of 0.30, 0.35, 0.40 and 0.45 g/cm. On the basis of, correlation and regression analyses performed by using dehydration time (h), drie...

[1] Robust responses and links between the tropical energy and water cycles are investigated using multiple datasets and climate models over the period 1979–2006. Atmospheric moisture and net radiative cooling provide powerful constraints upon future changes in precipitation. While moisture amount is robustly linked with surface temperature, the response of atmospheric net radiative cooling, de...

[1] We make use of microwave measurements of the tropical free tropospheric relative humidity (FTH) to evaluate the extent to which the water vapor distribution in four general circulation models is faithful to reality. The comparison is performed in the tropics by sorting the FTH in dynamical regimes defined upon the 500 hPa vertical velocity. Because microwave radiation penetrates non-rainy a...
