Study of Temperature and Moisture Distribution in Paddy in a Triangular Spouted Bed Dryer

Abstract

A triangular spouted-bed dryer has been designed as part of a hexagonal continuous dryer for paddy. In the triangular-bed dryer, the spout of drying air is placed in one corner of the drying chamber. Combining six triangular units with the spout located in the center of the dryer allows a continuous process and reduces energy consumption due to the reduction of heat losses. The current study focuses on the distribution of moisture and temperature in an individual triangular bed. Models of distribution have been developed in order to provide a better understanding of the phenomena and to help in scaling-up of the design.
