Continuing my discussion of the psychrometric chart and how to use it, in my last column, I showed a psychrometric chart, plotting four points. Allow me to proceed with the topic by picking up our ongoing example and taking it further, by putting that air inside a piece of process equipment such as a dryer or oven.

My "Tools of the Trade" series dealt with various instruments used in the acquisition of system parameters. For the data collected to have some value requires understanding and manipulation of the data, ultimately resulting in a model of your system. The next few "Drying Files" will deal with the interpretation and manipulation of this data so that a better understanding of the operation can be gleaned.

Performing a "dryer audit" is a mainstay of any drying specialist, and every reputable company that sells equipment has people specifically trained to perform these audits. Even with vast experience and all the necessary equipment, it takes someone skilled in the art significant time to capture all of the pertinent field data. Thereafter, another considerable investment is made into analyzing the data to manipulate it into a meaningful form.
