Convective air drying characteristics of mango slices at different drying temperatures (60°C, 70°C and 80°C), at an air velocity of 0.5 m/s and for constant sample thickness (3 mm) were investigated. Results indicated that drying took place in the falling rate period. Drying time decreased considerably with increased drying temperature. Three mathematical models; namely, Newton (Lewis), Henders...

Fruit leathers are dehydrated fruit products which are eaten as snacks or desserts. They are flexible sheets that have a concentrated fruit flavor and nutritional aspects. Most fruit leathers are prepared by mixing fruit puree and other additives like sugar, pectin, acid, glucose syrup, color, and potassium metabisulphite and then dehydrating them under specific conditions. Various drying syste...

in this study, the possibility of microwave finish drying for two types of dried grapes (natural and sultana) was investigated. the samples were washed in water bath at given temperature ranges (25 and 45 c) for 30 to 60 minutes. after dewatering the samples, they were dried using microwave (at two powers: 270 and 450 w) and hot air convective dryer (at 50 c). water gain (%), effective moistu...

Abstract The effects of different dehydration temperature (35, 50 and 70 °C) carrot slice thickness (3, 6, 9 mm), at the constant (hot) air speed mass load, on moisture ratio ( MR ) drying DR in thin layer convective process were investigated. mathematical models Modified Page, Logarithmic, Two-term (for ), Gauss model most appropriate. Based obtained results for R 2 RSME , optimal parameters s...

An adjoint sensitivity analysis of the relaxed Arakawa–Schubert scheme in the National Aeronautics and Space Administration GEOS-1 GCM with respect to perturbations in large-scale environmental fields was conducted. The response functions were defined as measures of the strength of convective cloud precipitation, the cloud-induced heating and drying (moistening) in both the instantaneous and ti...

Wood drying (in particular lumber drying), which almost entirely determines the quality of wooden products, is one most complicated and energy-consuming processes in wood processing. Convective lumber, all its varieties, remains common by far. Computer modeling usually based on solving systems differential heat mass transfer equations. The methods for such systems, both analytical numerical, ar...
