Inverse techniques are tools widely used in the determination of parameters involved in the modelling of industrial processes. In the present work the method Restricted Random Window (R2W) is employed to estimate the parameters of mass transfer involved in the chromatographic separation of glucose and fructose from cashew apple juice. The R2W is a simple stochastic method, that evaluates the cost function for random estimates within the domain for the parameters to be adjusted, with new random searches performed within a restricted domain in the vicinity of the best solution candidates for the problem of interest. In the chromatographic process a new approach phenomenological is used, called "front velocity", which considers as the dominant factor in the molecules transfer in chromatographic columns the liquid phase velocity. The R2W method has shown to be effective in the model parameters determination yielding a good agreement between the computational simulation and experimental data.
