the kinetics of forced convective air-drying of papaya (carica papaya l.) slices pretreated in osmotic solution
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...
متن کاملShrinkage of papaya (Carica papaya L.) during convective drying: Influence of glass transition phenomenon
The aim of the present work was to study the shrinkage phenomenon during convective drying of papaya cubes and relate its extension with glass transition. A convective tray dryer was used for the experiments, which were carried out at air temperatures of 40 and 70°C and air velocity of 1.0m/s. The shrinkage behaviour was accomplished by total area and apparent volume alterations along drying. S...
متن کاملstudying drying kinetics of button mushroom pretreated by osmotic dehydration
dehydration is one of the most common preservation methods for button mushroom. dried mushroom slice and powder is used in formulation of soups and sauces. in this study, the effect of osmotic pretreatment on drying kinetics of button mushrooms was studied. thin slices of mushroom were immersed in osmotic solution containing 5% sodium chloride and 0.5% calcium chloride at a temperature 40 °c fo...
متن کاملStudy on Drying Kinetics of Paddy Rice: Intermittent Drying
The intermittent drying characteristics of an Iranian popular paddy rice variety were experimentally investigated to determine the drying kinetics and obtain the effective moisture diffusivity. A lab-scale fluidized bed dryer was designed and constructed to enable obtaining the required results while controlling critical drying parameters. The effects of drying temperature and tempering per...
متن کاملOptimization of osmotic dehydration of papaya followed by air-drying
Papayas are a fragile fruit; characteristic that limits large-scale exportation from the producing centers to countries in temperate regions. Loss of fruit ranges from 10% to 40% and could be reduced if papayas were dried. The process of osmotic dehydration followed by air-drying was studied and modeled for papaya preservation, so it could be optimized. The developed model has been validated wi...
