Studi Eksperimental Pengembangan Freeze Vacuum Drying Menggunakan Thermal Energy Storage Untuk Mengeringkan Tanaman Lidah Buaya

ABSTRACT
Aloe vera is known for its various health benefits; however, its high water content requires proper post-harvest processing to preserve nutritional quality. One effective method is vacuum freeze drying, which maintains product quality but suffers from low energy efficiency. This study investigates the use of Thermal Energy Storage (TES) to recover and reuse waste heat from the condenser during the drying process. The results show that the integration of Thermal Energy Storage (TES) consistently improves drying efficiency and reduces energy consumption. The system equipped with TES was able to remove higher moisture content compared to the system without TES, achieving 68%, 66.82%, and 65.2% moisture removal for 2 kg, 3 kg, and 4 kg aloe vera samples respectively, while the non-TES system achieved only 58.57%, 61.13%, and 47.43%. Additionally, the Coefficient of Performance (COP) increased in all mass variations, indicating better thermal efficiency. COP values with TES were recorded at 2.23, 2.33, and 2.51, compared to 2.08, 2.17, and 2.34 without TES. The use of TES also led to electrical energy savings of 259 Wh for 2 kg, 186 Wh for 3 kg, and 157 Wh for 4 kg of aloe vera. These findings confirm that the integration of TES into freeze vacuum drying systems is effective in enhancing energy efficiency, lowering power consumption, and improving the drying performance of aloe vera.
