Prediction of dry mass glass transition temperature and the spray drying behaviour of a concentrate using a desorption method
Abstract : A predictive tool (SD(2)P (R)) based on a drying by desorption method was recently developed in order to determine the key process parameters values prior to spray drying. However, the SD(2)P (R) software cannot currently take into account the risk of stickiness during the process. In the study reported here, new standardized desorption method was tested and with this new method an equation was proposed to evaluate the dry glass transition temperature (T(g)) of a concentrate according to its total solid content, its viscosity and its average evaporation rate. The concentrate's behaviour during spray drying could then be predicted on the basis of the Tg. Four validation experiments were performed using different infant formula samples
