Drying kinetics of rice using a flatbed dryer with a hot air source from a biomass waste pyrolysis reactor

Abstract

Abstract This study aims to evaluate the process of rice drying using a flatbed dryer integrated with a biomass waste pyrolysis reactor as a heat supplier. The integration of dryer equipment with pyrolysis reactor aims to replace the use of fossil fuel energy with biomass as an eco-friendly source and abundantly available in nature. The current investigation assessed how tray height and drying temperature affected rice’s moisture ratio, drying rate, and drying characteristics. The drying air temperature of 70°C and the tray height of 40 cm were found to yield the optimum drying outcomes, according to the results. The best drying kinetics model that can describe the rice drying process is the Page model.
