A study of drying parameters on the process Pisum Sativum bean was carried out. The effects temperature moisture air from 40 ° C to 80°C time and kinetics were demonstrated not only conventional electric dryers but also heat pump dryers. Besides, checking steady operation dryer considered. results show that, when rises, shorter faster removal content can be obtained for both systems. Drying in ...

In preparation for routine deployment in a network of greenhouse gas monitoring stations, we have designed and tested a simple method for drying ambient air to near or below 0.2 % (2000 ppm) mole fraction H2O using a Nafion dryer. The inlet system was designed for use with cavity ring-down spectrometer (CRDS) analyzers such as the Picarro model G2301 that measure H2O in addition to their princi...

rotary atomizers are commonly used in spray dryers to atomize feed. one destructive effect of wheel rotation is the creation of a vacuum inside the wheel that conducts hot air from the chamber into the wheel and can lead to atomizer blockage and an explosion. the present work determined the air-pumping characteristics of a rotary atomizer with a 50 mm wheel diameter. the vacuum pressure and pow...

who offered both ever-insightful comments and encouragement. My committee member Matthew Dryer, who spent much of his time reading and commenting on this project, in spite of his extremely busy schedule. My committee member Leonard Talmy, who gave me support and warm encouragement.
