The introduction of affordable control networks for peanut dryers has made it possible to easily vary the curing temperature based on ambient air conditions. Previous research has used ambient temperature, relative humidity, and humidity ratio as possible control parameters. Peanuts from the same field were cured using four 0.11 m dryers to a moisture content of approximately 0.11 kg kg. Four d...

The aim of this study was to optimize the extraction conditions for the extraction of phenolic compounds from Moringa oleifera leaves using response surface methodology (RSM). A user-defined design was applied to determine the effects of extraction time (min), extraction temperature ((o)C) and ethanol concentration (%), on total phenolic content (TPC) from Moringa oleifera leaves dried by three...

background & aim: kelussiaodoratissima mozaff is a valuable plant of apiaceae family that is used as medicinal and aromatic herb. according to the importance of drying treatment on quality and quantity of essential oil, the effect of different drying methods on essential oil yield and chemical composition of kelussia odoratissima mozaff was examined in this research. experimental:  this res...

In this work, we tried to evaluate mass transfer during a combined infrared-vacuum drying of kiwifruits. Infrared radiation power (200-300 W) and system pressure (5-15 kPa), as drying parameters, are evaluated on drying characteristics of kiwifruits. Both the infrared lamp power and vacuum pressure affected the drying time of kiwifruit slices. Nine different mathematical models were evaluated f...

OBJECTIVES To investigate the effect of air-drying pressure during ceramic primer coating on zirconia/resin bonding and the surface characteristics of the primed zirconia. METHODS Two ceramic primers (Clearfil Ceramic Primer, CCP, Kuraray Medical Inc. and Z-Prime Plus, ZPP, Bisco Inc.) were applied on the surface of air-abraded zirconia (Katana zirconia, Noritake) and dried at 4 different air...

The effect of size reduction on the drying rate of cassava (Manihot sp.) and plantain (Musa paradisiacal) chips were analyzed comparatively through physical and statistical operations. In this study, duplicate cassava and plantain chips were used with varying thicknesses of 2mm, 4mm, 6mm and 8mm. The chips were subjected to natural sun drying with ambient temperature of 29C and artificial tray ...

A forced convection solar drier is designed with evacuated tube collector and a blower. The performance of the designed drier is evaluated by carrying drying experiments at Thanjavur District, Tamilnadu, India with amla. Solar drying of amla is carried at different air velocity flow rates – 4m/s, 4.25m/s and 4.5m/s and is compared with natural sun drying. The temperature of the drying chamber r...

Two identical prototype solar dryers (direct and indirect) having the same dimensions were used to dry whole mint. Both prototypes were operated under natural and forced convection modes. In the case of the later one the ambient air was entered the dryer with the velocity of 4.2 m s(-1). The effect of flow mode and the type of solar dryers on the drying kinetics of whole mint were investigated....
