This article contains a verbal and mathematical description of drying process inside ATM-52 spray dryer for ceramic paste production. Through the application of a modeling methodology, it was defined as an objective to be able to describe, by means of a phenomenological basis, the temporal variation of humidity in the outlet stream of the ATM-52 spray dryer. This variable is the most critical in the process and it’s the most fluctuating to measure in real time and only laboratory methods are available to obtain measurements. To achieve the objective, a series of assumptions were made, allowing to describe the model by a set of differential ordinary equations, The most important assumption is that the mass transfer phenomena is significant when streams flow is in co-current. Once the set of equations were obtained, through physical-chemical relations of the process, parameters values were assigned and computational verification was applied. The model was validated using the values in steady state obtained from the real process.

Keywords : model; mass and energy balances; spray drying; slurry; mass transfer.
