Drying kinetics of granular Nylon-6
نویسندگان
چکیده
In this study, the drying kinetics of granular nylon-6 has been investigated. Single particle drying experiments were carried out in a magnetic suspension balance (MSB) using dry air as drying agent. The comparison of measured and simulated data using Vrentas-Duda diffusion model shows a satisfactory prediction of mean particle moisture content and drying rates. The Flory-Huggins model predicts well the measured sorption equilibrium. The simulation on the influence of air inlet humidity predicts well the residual moisture content and drying time.

Evaluation of Drying Methods With Respect to Drying Kinetics and Mineral Contents of Dill and Parsley
Dill (Anethum graveolens L.) and parsley (Petroselinum crispum Mill.) were dried by using sun and oven (50oC) drying methods. Oven drying decreased the drying time approximately 50% when compared to the sun drying method for both herbs. K, Ca, P, Mg and Na were the most abundant elements in dill and parsley samples. Oven-dried samples had higher mineral values than that of the su...

In the present work, the drying of calcium carbonate in a batch spouted bed dryer with inert particles has been investigated experimentally. The effect of several operating parameters including air temperature (90, 100, and 110 ˚C), air velocity (Ums, 1.2 Ums, and 1.5 Ums), and dry solid mass (5, 10, 20 g) has been studied. The Taguchi method has been applied to determine the optimal parameters...
