The Simulation of Fluid Flow with a Vortex Generator 35° toward the Y-axis to Heat Transfer in Spray Dryer

The Spray Dryer is a spray drying machine to change liquid into dry powder. can be defined by the process in cylinder, utilizing air heated heater and flowing through blower connected vortex generator with an angle of 35° Y-axis. causes formation turbulence airflow. Heat transfer occurs between hot flow milk droplets so that becomes This research aims see phenomenon, namely intensity, airflow velocity, heat flux, temperature distribution compared experiment used four conditions inlet. There 80°C, 90°C, 100°C 110°C. this dairy cow’s mixed water maltodextrin, which has density value 1056 kg/m 3 specific 3930 J/kg K. machine’s cylinder diameter 0.5 m wall thickness 1 x 10 −3 height 2 capacity 1.27 l/hour time 80 minutes. speed 16 m/s cross-sectional 9,5 −2 debit 0.11 /s.
