Abstract
This study aimed to analyze the effect of inlet temperature and airflow direction variation of a spray dryer on the product’s water content and minimum droplet temperature using the means of computational fluid dynamics (CFD). The airflow direction types were mixed and co-current. The k-ω SST and standard k-ε models were used to simulate the flow, and the Eulerian-Lagrangian approach was used to predict the motion of particles. The simulation results showed that water content decreased as temperature increased for both airflow directions and vice versa for the minimum droplet temperature. A mixed flow spray dryer produced the lowest water content (0%) product with droplets diameter of 10 µm and 30 µm and an inlet temperature of 180 ℃. The lowest minimum droplet temperature (32.73 ℃) occurred in the mixed flow spray dryer with an inlet temperature of 100 ℃.
