Última Assessment of differences between products obtained in conventional and vacuum spray dryer Ciênc. Tecnol. Aliment. RAMOS,Fernanda de Melo; OLIVEIRA,Cíntia Carla Melgaço de; SOARES,Ana Silvia Prata; SILVEIRA JUNIOR,Vivaldo. Abstract In this work, an experimental unit of a vacuum spray dryer was built. This prototype attempted to combine the advantages of freeze-drying (drying at low temperatures due to vacuum) and spray drying (increase of surface area aiming the improvement of heat transfer efficiency). Maltodextrin solutions were dried in the vacuum operated equipment and in conventional spray dryer. The vacuum spray dryer system allowed obtaining powder at low temperatures due to the lowering of pressure conditions (2-5 kPa) inside the drying chamber. The products obtained in the two systems were characterized and compared for particle size distribution, moisture content, water activity, bulk density and solubility in water. The processes yields were also evaluated and... Tipo: Info:eu-repo/semantics/article Palavras-chave: Thermosensitive compounds; Vacuum spray dryer; Vacuum; Maltodextrin.
