3.3 Drying kinetics for Nylon-6 and Polypropylene
Nylon-6 and Polypropylene were selected for studying drying kinetics using solar chimney dryer, because of
their extensive use in plastic industry. Cylindrical pellets of Nylon-6 and polypropylene were dried using solar
chimney dryer. Three trials of Nylon-6 and two trials of polypropylene were carried out to check the reproducibility.
All the experiments were started at 10 am in morning and stopped at 4 pm in afternoon. Moisture lost and product
temperature were measured at every hour during the trial.
