Analisis Distribusi Temperatur Dan Kecepatan Aliran Udara Pada Drying Chamber Tipe Co-Current Untuk Spray Drying Dengan Metode Numerik

ABSTRACT
Spray drying is a widely used drying method to convert liquid feed into powder, especially for heat-sensitive materials such as coconut milk. However, this process often encounters the issue of wall deposition, where particles adhere to the drying chamber walls, reducing drying efficiency and product quality. This study aims to analyze the temperature and airflow velocity distribution in a co-current type drying chamber with a modified design using two tangential air inlets, through numerical simulation using Computational Fluid Dynamics (CFD). Simulations were conducted by varying the inlet air flow rates at 10 m³/h and 30 m³/h, and inlet air temperatures from 120°C to 150°C. The realizable k-ε turbulence model was used along with the Discrete Phase Model (DPM) to track particle behavior. The results showed that the dual tangential inlet configuration effectively created a swirling flow that enhanced the mixing of hot air and droplets, resulting in a more uniform radial temperature distribution. The condition of 30 m³/h air flow at 150°C provided the most optimal temperature distribution and reduced potential wall deposits within the chamber. The simulation was validated with experimental data, yielding a deviation of less than 10%, indicating that the numerical model used is sufficiently representative. This study provides recommendations for drying chamber design and operating parameters to improve the spray drying efficiency of coconut milk.
