This research aims to study the ability of silica sand with an average diameter of 10 mm for different thicknesses of thermal energy storage to store the heat energy during the turmeric drying process. Drying is a method that uses thermal energy to remove moisture from a material. Direct sunlight or specialised electrical equipment can facilitate drying. The process for drying materials is influenced by several aspects, including the product's surface characteristics, drying temperature, airflow, steam pressure, energy supply, and the specific type of material involved. Drying rates accelerate with increased temperatures and reduced relative humidity. Regulating these parameters requires diligent supervision via the installation of numerous sensors at different positions within the dryer. Conversely, thermal energy storage applications have comparatively underutilised solid-state thermal energy storage (TES) materials like sand. Consequently, the use of silica sand is essential for thermal energy storage, mitigating the constraints of solar dryers that function exclusively during daylight hours. The highest thickness of sand has a higher drying rate compared to the lowest thickness of sand, and there is no thermal energy storage condition for turmeric drying. Additionally, the previously mentioned amount of sand retains more heat storage compared to the lowest thickness. Therefore, it can be concluded that as the thickness of silica sand increases, the temperature of thermal energy storage also increases, which accelerates the drying process.
