ABSTRACT Indonesia is one of the largest coconut producers in the world, with coconut milk being one of its high-value derivatives. However, coconut milk is highly perishable and prone to degradation. To improve shelf life and product stability, the spray drying method is employed to convert liquid coconut milk into powder. Nevertheless, this process often encounters challenges such as wall de…
ABSTRACT Spray drying is an effective method to convert liquid coconut milk into powder; however, conventional cyclone separators still face challenges in particle separation efficiency due to re-entrainment phenomena. This study aims to design and analyze the performance of a cyclone separator modified with a Circumfluent Cyclone (CFC) configuration and the addition of a Convergent Vortex Fin…
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…
ABSTRACT Implementation of development on a project scale has great potential for environmental damage to occur. The building and construction sector contributed approximately 32% of global energy consumption and 34% of energy-related carbon dioxide (CO2) emissions in 2023. There has been an increase in the average daily temperature of at least 0.74ºC per year over the past two decades with t…
