Kinetic parameters identification of conductive enhanced hot air drying process of food waste

mathematical modeling of onion drying process using hot air dryer

the main purpose of present paper is the modeling of onion drying process and investigation of experimental data of onion drying obtained with using a hot air dryer. therefore some empirical and regression models have been considered to fit experimental data. the investigation of the experimental data shows the onion drying happens only in falling rate zone. the experimental data have been fitt...

optimization of drying process of parsley using the combination of hot air and microwave methods

in this study, parsley was dried using three drying methods: hot air (50, 60 ‎and 70 ºc), microwave (90, 180, 360, 600 and 900 w) and a combination of ‎hot air – microwave (60ºc and 360w). selection of the optimum levels for ‎drying in combination method took place with quality tests of dried ‎samples. the drying data of parsley with hot air and microwave methods ‎was fitted with eight models: ...

Mathematical Modeling of Hot Air Drying of Spinach Leaves in Universal Hot Air Oven

The objective of this study was to develop a model for drying characteristic curve of Spinach in Universal Hot Air Oven .Drying experiment were conducted using a constant air velocity2.2m/s and three drying air temperature of 55, 65, and75 o C with two pretreatment conditions and load densities that are given respectively condition (Blanched and Unblanched) load density (3kg/m 2 , 3.5 kg/m 2 )....

Kinetic Models for Colour Changes in Kiwifruit Slices During Hot Air Drying

The colour changes that occur in kiwifruit during the dry process were experimentally studied in order to determine the magnitudes of the parameters for a corresponding colour change model. The drying experiments were carried out under five air temperatures of 40, 50, 60, 70 and 80°C, air velocity of 1.0 m/s and kiwifruit slice thickness of 4 mm. The colour parameters for the colour change of t...
