In this study, the effects of microwave power, vacuum degree and load weight on moisture content seedless white grapes (Vitis vinifera L.) during drying were investigated. The result found that drying, effective diffusivity (Deff) ranged between 1.0232 × 10−9 4.6354 m2/s. Deff values increased with increase in power decrease weight, played a relatively minor role. kinetics ratio time establishe...

The genus Haplophyllum, which belongs to the Rutaceae family, includes 18 species in Iran. In this study, after collecting plant material, botanical identification and suitable drying, the essential oils from aerial parts of Haplophyllum robustum Bge. were extracted by three different isolation techniques, conventional hydrodistillation (HD), microwave-assisted hydrodistillati...

the effects of drying method and prediction of the essential oil contents of two thyme genuses (thymus vulgaris and zataria multiflora) were investigated using scanning electron microscopy (sem). t. vulgaris was dried at 30°c under controlled conditions while z. multiflora dried through traditional method and at 50-70°c. in the middle and edge of z. multiflora leaves, 18.4 and 14.9% of glands w...

introduction drying foods, fruits and vegetables is a suitable method to reduce post-harvest losses of the crops. drying is considered as a simultaneous heat and mass transfer process. various physical, chemical and nutritional changes occur during drying of foods and are affected by a number of internal and external heat and mass transfer parameters. external parameters may include temperature...

Drying can remove the moisture and volatile fraction from biomass to achieve purpose of improving pyrolysis performance feedstock. In this project, three different drying treatments (blast, vacuum microwave) were applied rice husk in order investigate effect conditions on pyrolytic properties husk. Thermogravimetric experiments performed materials at heating rates (10°C/min, 20 °C/min, 30 °C/mi...
