spray dryerflow instabilityCFD simulationIn this paper, turbulent flow behind a sudden pipe expansion followed by a contraction is simulated numerically, in order to investigate the effect of the downstream contraction on the flow instability in non-swirling flows, as well as in weakly swirling ...

The evaporation of a solution droplet in a spray dryer is a coupled heat and mass transport problem. The process is driven by the difference between the vapor pressure of the solvents and their partial pressure in the gas phase. The rate of evaporation is determined by the balance of energy ...
Heat recovery from a spray dryer using a run-around coil system : A Demonstration Project at the Clayton Aniline Company Ltd, Manchester, U.K. ☆Detailed monitoring has not yet been completed, but preliminary information and design calculations estimate that for the modified exchanger, energy ...
Although this work does not involve mass transfer, the overall aerodynamics and heat transfer characteristics as well as particle trajectory calculations are relevant to industrial spray dryer modeling as well.doi:10.1142/9789812771957_0030Hee Joo Poh...
Three-dimensional CFD simulations of dust explosion in the spray tower for six different configurations of safety vents located at the top and side walls of the dryer were carried out. In the calculations, in which dust was replaced with a flammable gas-air mixture, the following parameters of...
Their solution applied in spray drying using ANN (Figure 3) was to predict the physical attributes of maltodextrin (17.5 DE) as a function of spray dryer operating parameters and feed conditions. The authors made use of the two-layer MLPN for predicting, for which the physical properties of ...

Introduction During product development, it is essential to identify the appropriate critical material attributes (CMAs) and critical process parameters (CPPs) that ensure the safety,...
The concentrate from nanofiltration was further processed to a dry powder by spray-drying (Buchi Mini Spray Dryer Model 191, Buchi Labortechnik AG, Flawil, Switzerland). Initially, the concentrate was partly evaporated (rotary evaporator Heidolf, Laborota 4003, Heidolph Instruments GMBh & CO KG, Sc...
