A prototype of a constant flow type of Solar Gelugur Acid (Garcinia atroviridis) dryer using 2 racks was investigated experimentally. The aim is to explore the performance and characteristics of the prototype. A box of solar acid Gelugur (Garcinia atroviridis) is designed and made. In experiments the thickness of Acid Gelugur consists of 3 mm and 5 mm. The speed of heat flow sourced from the solar collector is 1.5 m/s. Prototype exposed to sunlight located in the city of Medan. The average solar collector temperature is 92.20°C, the drying box temperature averages 33.54°C, Gelugur Acid Moisture average 94.42%, and Ambient Temperature data measured System efficiency is analyzed. The results showed that with a flow velocity of 1.5m/s constant, the percentage of acid content in Acid Gelugur (Garcinia Atroviridis) with a slice thickness of 3mm was greater than that of 5mm with drying for 8 hours.
