Today the use of pretreatment operations to reduce time, energy and cost of drying of agricultural products and foodstuffs are taken into consideration. In this study the Rosemary herb dried by using the microwave pre-treatment at three treatments (90 W for 5 min, 180 W for 2.5 min and 360 W for 1.5 min) and control treatment (without pre-treatment) in a hot air dryer at temperatures of 40, 50 ...

During September–October 2001, the East Pacific Investigation of Climate Processes in the Coupled Ocean– Atmosphere System (EPIC-2001) intertropical convergence zone (ITCZ) field campaign focused on studies of deep convection in the warm-pool region of the eastern Pacific. This study combines C-band Doppler radar, sounding, and surface heat flux data collected aboard the R/V Ronald H. Brown dur...

Microwave (MW) offers a unique heating mechanism, which volumetrically pushes internal moisture to the surface during drying of water-rich foods such as fish. However, due uneven power distribution, continuous application MW energy causes excessive localized heating, resulting in deterioration food quality. Incorporation other techniques convective, vacuum, osmotic, and freeze-drying with has b...

[1] Geostationary satellite observations are used in conjunction with an objective pattern-tracking algorithm to describe the Lagrangian evolution of convection, clouds and water vapor in the tropical upper troposphere. This analysis reveals that larger convective events within a Lagrangian air mass are associated with larger and longerlived cirrus anvil shields. Convective systems which genera...

In this paper an attempt is made to evaluate the convective mass transfer coefficient during drying of jaggery in a controlled environment. In this method, different masses of jaggery were used. The jaggery was dried in the roof type even span greenhouse with a floor area of 1.2x0.8 m in natural and forced convection mode at atmospheric pressure till it attained almost no variation in mass. The...

This study attempts to understand interactions between midlatitude convective systems and their environments through a heat and moisture budget analysis using the sounding data collected from the Midlatitude Continental Convective Clouds Experiment (MC3E) in central Oklahoma. Distinct large-scale structures and diabatic heating and drying profiles are presented for cases of weaker and elevated ...
