Heat and mass transfer modeling during continuous flow processing of fluid food by direct steam injection

Analysis and Design of Direct Steam Injection for Tomato Concentrate Sterilization

“…In Figure 1, the variation of the rheological parameters with temperature is reported: K significantly decreases with temperature, while n increases with temperature. Values have been obtained using eqs (4) and (5).…”

“…Among the different thermal treatments available [4], continuous direct steam injection (DSI) is widely used to quickly raise the temperature of a process media, either for pure heating or for sterilization of the product [5]. The basic idea is to heat the fluid by injection of superheated steam from several nozzles, in order to reach homogeneous heating.…”

“…steam properties and product flow rate), a numerical model is required for the evaluation of temperature history and distribution inside the product [8]. The available literature on DSI is mostly limited to the case of steam injection in a stagnant liquid, typically water [9,10], while food applications are focused on the evaluation of the biochemical behavior of the fluid [5].…”

Computational transport phenomena in bioprocessing with the approach of the optimized source term in the governing equations

“…DSI can be modeled by CFD, to show the directions for improved energy and functional efficiencies. However, no modeling is available in the available literature, except in [10] who reported on the interactions between fluid mechanics, heat transfer, and functional issues such as the evolution of bacteria and vitamins (or bio-indicators / in Eq. ( 3)).…”
