Many of the processes of food production are based on thermal treatments as part of their processing of raw materials and / or treatment of food materials preservation. An industry located in Mexico that dehydrated food system has a process that involving heat exchanger concentric tubes whose efficiency must be estimated as part of the quality assurance system. In this study the prediction of log reductions of microbial survival was performed with two linear models, isothermal and non-isothermal. The results point to have a reduced capacity beyond the needs of the industry, with the respective consequences in quality and economy.
