Experimental Study on the Ventilation Resistance Characteristics of Paddy Grain Layer Modelled with Response Surface Methodology

The ventilation resistance of air flow through rice grain layers is one the key parameters affecting drying uniformity as well energy consumption process. In order to reveal variation characteristics with paddy moisture content, velocity and bed layer depth are needed. A second model was fitted pressure drop using response surface methodology results compared those Ergun model. showed that increases increase depth, interactions between have most significant influence on drop. Moreover, a second-order polynomial based RSM established by similar
