the objective of this study was to examine the effects of the fluidized-bed drying me-thod on the final quality of two varieties of iranian rice, medium- and long grain. the re-sults were compared to that of paddy drying using a traditional method. rough rice was treated in the fluidized bed drier at 140ºc for 2 minutes. similar samples were dried for 8-10 hrs by the traditional method. dried s...

Positron emission particle tracking (PEPT) has been used to investigate the motion of radioactively labeled tracer particles attached fabrics and solid fabric enhancer (SFE) delivery articles, such as dryer sheets, in domestic clothes dryer. This work examines dynamics within across a range operating conditions. Six regions drum are identified, demonstrating movements experienced by items durin...

The fascination for hierarchically structured hard tissues such as enamel or nacre arises from their unique structure-properties-relationship. During the last decades this numerously motivated the synthesis of composites, mimicking the brick-and-mortar structure of nacre. However, there is still a lack in synthetic engineering materials displaying a true hierarchical structure. Here, we present...

The unpredictable rise and frequent scarcity of fossil fuel accelerated the continuous search for an alternative power source. Solar is one of the renewable and sustainable sources of power that attracted a large community of researchers from all over the world. This is largely due to its abundant in both direct and indirect form. As such the development of efficient and inexpensive equipment f...

Rice is the main food in Indonesia. drying by using traditional method directly under sun light can require a long time to complete. The aim of this study investigate appropriate kinetics modeling rice with applied fluidized bed dryer. A 2-cm thickness has been dried at various temperatures (50℃, 60℃, and 70℃) air velocity 10 m/s from hot dryer obtained pyrolysis process. selected based on agre...

Three different drying methods, microwave spouted bed drying (MSBD), microwave-vacuum drying (MVD), and hot air drying (AD), were used to dry diced sweet potato. The drying characteristics and product quality are discussed in terms of the drying kinetics, rehydration ratio, expansion ratio, breaking force (crispness), product colour, and retention of β-Carotene. As expected the drying rates in ...
