description: The production process of liquid palm sugar requires a significantly long processing time, which can hinder farmers' productivity. One innovation developed to address this issue is the use of an electric heater in a vacuum evaporator system to accelerate the evaporation process at low temperatures, thereby preserving the quality of the palm sap. This study aims to determine the effect of heater design variations on thermal efficiency and evaporation rate in the production of liquid palm sap. The tests were conducted using three types of heaters: tubular (U), spiral, and finned tubular (U), each with a power of 500 watts and a vacuum pressure of -0.7 bar, used to heat 20 kg of liquid palm sap for 120 minutes. The results showed that the finned tubular heater had the highest thermal efficiency at 78.9%, due to its large contact surface area (1,112 cm²). However, the spiral heater demonstrated the highest evaporation efficiency of 8.56% and the highest evaporation rate of 1.67 × 10⁻⁵ kg/s, thanks to its even heat distribution and stable temperature throughout the process.
