Mathematical Modelling of Thin Layer Drying Kinetics of Onion Slices Hot-air Convection, Infrared Radiation and Combined Infrared-Convection Drying

quality characteristics of persimmon slices during infrared and hot- air drying

introduction: one of the most important aspects of food preservation is controlling the moisture of material such as fruits.dryingis considered as important method to controlbacteriasafely using reduction of moisture. the hot air drying method has been widely adopted in manufacturing of conventional dried food.nowadays, infrared radiation (ir) has significant advantages over conventional drying...

Drying kinetics and mathematical modeling of hot air drying of coconut coir pith

Drying kinetics of coir pith was studied and the properties of compressed coir pith discs were analyzed. Coir pith particles were oven dried in the range of temperatures from 100 to 240 °C and the rehydration ability of compressed coir pith was evaluated by finding the volume expansion. The optimum drying temperature was found to be 140 °C. Hot air drying was carried out to examine the drying k...

The Influence of Abrasive Pretreatment on Hot Air Drying of Grape

The drying of grapes is a more complex process compared to the dehydration of other agricultural materials due to the necessity of a pretreatment operation prior to drying. Grape drying to produce raisins is a very slow process, due to the peculiar structure of grape peel, that is covered by a waxy layer. Its removal has been so far carried out by using several chemical pre-treatments. However,...

Effect of Ultrasound Pretreatment on Wood Prior to Vacuum Drying♠

The influence of ultrasonic pretreatment prior to vacuum drying of Chinese fir specimens was examined in this work. In the pretreatments, wood samples were immerged in a distilled water bath and were treated using two wave frequencies for four different elapsed times to investigate effects of ultrasonic frequency and treatment duration. Then the wood samples were vacuum-dried at 80°C and absolu...
