The Experimental Research on Grain Storage Heat and Moisture Transfer

摘要

Different moisture content corns were stored by the self-made simulated silos. Heat and moisture transfer in different initial moisture content simulated silos were analyzed during the static storage. The experiment result indicated that the bottom grain layers were acutely affected by the external condition in simulated trial silos. The average minimum temperature all appeared at the bottom of the four trial silos. Internal temperature and relative humidity at each layer increased with the increase of moisture content. In the process of the experiment, heat and moisture content mainly concentrated in the upper layer of the silo.
