Abstract
In order that the art of drying, or in other words the process of removing liquid from a mixture, may become a field of true engineering endeavor, it must be freed from the existing confusion with regard to classification and terms, and the analytical approach to the problem must be facilitated.
In this paper the authors classify the liquids as to kind, nature, and state, enumerate the means available for their removal, and discuss briefly the limitations of the various drying methods with regard to the material being processed and the results obtained.
A graphical method of analyzing air drying, the most widely used drying process, is described by the authors, and by means of this analysis, terms which are now confusing are defined and factors governing the performance of drying equipment are explained.
