Kinetics of polymer dispersion drying dy the conductionmethod

Abstract

The effects of conduction heating at the drying surface temperatures ranging from 50° to 90°C for thin layer conduction drying of polymer dispersion were studied. Results show that polymer dispersion at 52 percent initial moisture contants dried initially under constant rate period for a very short time and then dried under falling rate period. The empirical drying equations, developed before for the above drying conditions can be used to predict the drying time with fairly good accuracy.
