Vacuum drying of Salicornia herbacea L. was performed at different drying temperatures (50, 60, 70, and 80°C) to evaluate the drying characteristics and the effect of drying temperatures on the quality of Salicornia. As the drying temperature increased, the drying time decreased significantly (P< 0.05). The drying rate decreased with decrease in moisture content and increase in drying time. On ...

intermittent drying is a satisfactory technique for drying of heat sensitive grains especially rough rice. this method consists of two separate stages applied intermittently: drying and tempering. in this work, intermittent drying of rough rice is investigated both theoretically and experimentally. in order to characterize this process; a multi-scale model consisting of macroscopic and microsco...

Screening potential vaccine formulations during freeze-drying is a time-consuming task. High-throughput systems, consisting of small vials inside aluminium well plates, can accelerate formulation selection. However, heat transfer variations among due to the edge effect entail deviations in final product quality and bias results. This work investigates how vial position plate impacts flow receiv...

Water is the fundamental molecule for life on Earth. Thus, the search for hibernating life-forms in waterless environments is an important research topic for astrobiology. To date, however, the organizational patterns containing microbial life in extremely dry places, such as the deserts of Earth, the Dry Valleys of Antarctica, or Mars analog regolith, have been poorly characterized. Here, we r...

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...

microwave assisted fluidized bed drying is a novel drying technique which reduces drying time and yields higher quality products. in this study the effect of this method on color changes of whole and cut hazelnut kernels was investigated. the parameters of color and resulting total color change, chroma, hue angle and browning index were also calculated during drying in three temperatures (40, 5...

BACKGROUND Studies regarding the effect of various methods to increase the surface hardness of Type IV dental stone are not conclusive. Therefore, this study was carried out to evaluate the effect of air drying, micro oven drying and die hardener on surface hardness of Type IV dental stone. MATERIALS AND METHODS A standard metal die was fabricated; polyvinyl siloxane impression material was u...
