A solar drier assisted with evacuated tube collector is designed and developed to study and examine the drying Kinetics of muscat grapes in Thanjavur, Tamilnadu, India.  During the drying period, temperature at various places, relative humidity, wind velocity and mass of the sample are measured on hourly basis.  The outlet temperature of the collector and temperature within the chamber varies f...

Laser light scattering by a drying droplet of water fullerene suspension several micrometers in size was studied. Two light wavelengths were used. The evolution of refractive index and radius of the droplet was investigated. Resonant scattering was identified and analyzed. Some conclusions were drawn on the microscopic properties of the suspension. Supplementing measurements of samples obtained...

in this study, mathematical modeling of hot air-drying of thin-layer papaya (carica papaya l.) slices with 5±1 mm thickness pretreated in osmotic solution (50% sucrose) was investigated. thin-layer drying was conducted under three different drying temperatures of 40, 50 and 60 °c at a constant air velocity of 0.9±0.1 m/s and absolute humidity of 0.6 ± 0.02 g of water/kg of dry air. it was found...

Coffee (Coffea arabica L.) seeds are sensitive to desiccation and oxidative stress during drying processes. We investigated the effect of drying and moisture levels on germination-related gene expressions associated with enzymatic systems that prevent oxidative stress in coffee seeds. Coffee seeds collected at physiological maturity were subjected to slow and quick drying to 40, 30, 20, and 12%...

This paper deals with the experimental control of an infrared drying process of a water based epoxy-amine painting. This approach is based on a unidirectional diffusional modeling of infrared drying phenomena where both heat and mass transfers under shrinkage conditions are accounted for. The control problem is concerned with the tracking of any given trajectory for one of the characteristics (...

The process of thermal Marangoni drying is considered, which has been recently proposed for use in semiconductor production. The process allows ultraclean drying of semiconductor wafer surfaces at the end of a sequence of wet operations. A theoretical model is presented, which incorporates the movement of a thin liquid film on the semiconductor surface, heat exchange between the semiconductor a...
