Abstract

A global overview is presented of recent developments in spray drying. Recent advances in computational fluid dynamics modeling have provided new insights into the flow processes occurring within the spray chamber. This is important since detailed experimental measurements within an operating spray dryer are almost impossible due to the hostile environment of high-temperature two-phase flow, which may be unsteady, and the high cost that would have to incur. Some recent predictive studies on predicted effects of innovative chamber geometry, reduced pressure operation, operation in low dew-point air and superheated steam are presented. Also, a comparison is made between steady and unsteady state computations to highlight the critical issues. Predicted results on a horizontal spray chamber configuration are also presented. Finally, a brief survey is made on the recent literature on spray freeze-drying as well as multi-stage drying processes.

Récentes avancées dans la conception et l’optimisation des installations de séchage par pulvérisation: une vue d’ensemble

Résumé

Un inventaire des récents développements dans le domaine du séchage par pulvérisation est dressé. Les dernières avancées de la dynamique des fluides numérique ont permis d’obtenir de nouvelles représentations des processus d’écoulement ayant lieu à l’intérieur de la chambre de séchage. Ces modélisations sont très importantes car des mesures expérimentales détaillées à l’intérieur d’une installation de séchage en fonctionnement sont pratiquement impossibles à réaliser, en raison des conditions hostiles liées au flux à température élevée de deux phases, pouvant être irrégulier, et aux coûts qui seraient engendrés. Des études prédictives récentes sur les effets d’une géométrie innovante de la chambre, de conditions de pression réduite, d’air à bas point de rosée et de vapeur surchauffée, sont notamment présentées. Une comparaison des calculs réalisés dans des conditions stables ou instables est également réalisée afin de mettre en lumière les points critiques. Les résultats de la prédiction pour une configuration de chambre horizontale sont présentés. Enfin, les dernières publications sur le couplage séchage par pulvérisation-lyophilisation et les procédés de séchage multi-étage sont présentées rapidement.
