摘要：

A fluidized bed drier end point indication system has been developed based on the temperature difference technique. This paper describes the calculation of wet bulb temperature, an integral part of the control technique when drying non-aqueous solvents. The equations and control software control the end point of drying to within narrow limits of final moisture content, largely independent of variations in relative humidity of the air used for drying.
