Abstract:
Rose powder was produced by lab scale spray drying. Powders were analyzed for moisture content, solubility, hygroscopicity, bulk density, color and product recovery. The optimum inlet air temperature (160 ^oC) and feed flow rate (120 ml/h) resulted in the product with moisture content (5.3% wb), solubility (86.85%), hygroscopicity (0.259 g/g), bulk density (0.42 g/ml), color (21.03) and product recovery (8.42%). The powder showed a noticeable tendency to stick to internal surfaces of the drying chamber at higher temperatures.
