This research project aims to develop a mathematical model of the drying kinetics of the Castro Naranjal (CCN-51) cocoa variety to predict mass loss at intermediate temperatures. Experimental mass data were processed between 40 °C and 70 °C by applying the principle of parsimony using Newton’s model, selected for its technical efficiency as it requires the fewest variables. The Solver tool was used to optimize the numerical fit and extract the drying constants along with the start and end values of the process. Using these parameters, an interface was developed in MATLAB App Designer capable of predicting mass loss at intermediate temperatures through interpolation, while also incorporating the parallel visualization of two moisture analyzers to compare and validate the results. The interface simulations demonstrated high accuracy, recording deviations and relative errors of less than 5% between the two analyzers across the entire temperature range. When evaluating the optimization of data collection, it was found that it is possible to set fixed time intervals starting at 60 minutes without affecting or distorting the final kinetic curve
