A Correlation of Rotary Drum Cooler-Flaker Heat Transfer,

Abstract

A theoretical mathematical expression is presented which effectively correlates rotary drum cooler-flaker design and operating variables. Its application eliminates design uncertainties introduced by the previous empirical approach, and allows adjustment of operating variables for Optimum performance with a minimum of experimentation. The proposed equation is derived from the general statement for unidirectional unsteady state heat conduction in an infinite film layer. The simplifications made in the derivation include the assumption that the thermal properties of the liquid and solid phases do not differ greatly and that the latent heat of solidification averages in the sensible heat effect. Extensive tests conducted with plant-size drum cooler-flakers show experimental results to be in excellent agreement with data predicted by the suggested expression.
