The effect of air temperature, air velocity, and sample shapes (circle and square with the same cross-sectional area) on kinetic drying of potato slices in a tunnel dryer was investigated experimentally and a suitable drying model was developed. The experiments of drying of potato slices were conducted at an air temperature of 45-70°C with an air velocity 1.60 and 1.81 m sec(-1). Results showed...

An unsteady mathematical model of superheated steam fluidized bed drying process is established based on the transport process principles and computational fluid dynamics (CFD) method. The vapor-solid two-phase turbulent flow in the drying chamber is described with the Eulerian-Eulerian multiphase model. The model is solved by computer numerical simulation. The drying experiments of wet rapesee...

the objective of this study was to investigate the drying kinetics of oyster mushroom, pleurotus ostreatus mushrooms were dried using a cabinet-type convective dryer. air temperatures of 50, 60 and 70 oc were used for the drying experiments. the experimental drying data were fitted to different theoretical models to predict the drying kinetics. nonlinear regression analysis was performed to rel...

the objective of this research was to study the drying characteristics of powderedagricultural residues. drying experiments of wheat straw (triticum aestivum) wereconducted at four temperatures of 50, 60, 70, and 80°c by a thermogravimetric analyzer.drying temperature had a significant effect on the moisture change and drying time.there was no constant drying rate period, but a short rising rat...

Knitted fabrics are widely used by the underwear apparel industry due to their good elasticity. Modeling the mechanical behavior of knitted fabrics using Kelvin model is one of the discussed subjects in the textile industry. The purpose of this study is to investigate the accuracy of a nonlinear Kelvin model for determining the drying behavior of knitted fabrics. To fulfill this aim, genetic al...

in this study, mathematical modeling of hot air-drying of thin-layer papaya (carica papaya l.) slices with 5±1 mm thickness pretreated in osmotic solution (50% sucrose) was investigated. thin-layer drying was conducted under three different drying temperatures of 40, 50 and 60 °c at a constant air velocity of 0.9±0.1 m/s and absolute humidity of 0.6 ± 0.02 g of water/kg of dry air. it was found...

in this study, green pepper was dried by a laboratory scale microwave-convective dryer. the effects of microwave power on drying rate, effective moisture diffusivity, and energy consumption of green pepper were studied at four different microwave powers of 180, 360, 540, and 720w. the drying data were fitted to the four thin-layer drying models. the moisture reduction of the green pepper sample...

Abstract—Drying is a phenomenon that accompanies the hardening of hydraulic materials. This study is concerned the modelling of drying shrinkage of the hydraulic materials and the prediction of the rate of spontaneous deformations of hydraulic materials during hardening. The model developed takes consideration of the main factors affecting drying shrinkage. There was agreement between drying sh...

Drying kinetics of sour cheery is investigated in solar dryer with forced convection and under open Sun with natural convection. Drying data were fitted to different mathematical models, whose performance was investigated by comparing coefficient (R), reduced chi-square (Ç) and root mean square error (RMSE) between the observed and predicted moisture ratios. Among these models, drying model dev...
