To investigate the drying characteristics and mechanism during electrohydrodynamic (EHD) with ultrasonic pretreatment, pretreatment-assisted EHD method at different power values was used to carry out experiment of potatoes. this study, potato slices were pretreated (150, 180, 210, 240, 270 W) or without ultrasound for 30 min 30°C. The corresponding voltage 18 kV drying. moisture ratio, rate, co...

the canola drying process was investigated using three laboratory scale dryers connected to a computer which continuously recorded the drying processes of each unit. a completely randomized design (crd) with three replications was used for the statistical analysis. the effect of temperature (40°, 50°, 60°c) and air velocity (1, 2 m/s) on the drying kinetics of a monolayer were studied. the effe...

the aim of this research was to use osmosis-ultrasound compound pre-treatment and studying the time of drying and the potentiality to rehydration in dried samples of kiwi fruit (hayvard variety). the samples were drained in three timed phases, 10, 20 and 30 minutes in room temperature in 30, 50 and 70 bx in ultrasound bath osmosis solutions. the results of drying time showed that by decreasing ...

Abscisic acid-pretreated carrot (Daucus carota) somatic embryos survive dehydration upon slow drying, but fast drying leads to poor survival of the embryos. To determine whether the acquisition of desiccation tolerance is associated with changes in the physical stability of the cytoplasm, in situ Fourier transform infrared microspectroscopy was used. Although protein denaturation temperatures w...

response surface methodology (rsm) was employed to determine the optimum processing conditions leading to maximum anthocyanin, phenolic compound and antioxidant activity during osmo-ultrasonic pretreatment followed by hot air drying of black cherry fruit. temperature (40, 50 and 60ºc), sucrose content (40, 50 and 60% w/v) and ultrasound frequency (0, 65 and 130 khz) were the factors investigate...

Increasing demands for cement, iron and steel industries for refractories with suitable workability in severe conditions (without any environmental risks), make the refractories’ researches to be an active area. Refractories containing Spinel has been developed with addition of chromia as a substitute in refractories using Magnesite - chromite. In this research, different amounts of Cr2O3 were ...
