Abstract
The purpose of this research was to design and perform an evaluation of the galangal washing machine using pressurized water spray at water flow rates of 10, 20, and 30 l/min and speeds of 30, 50, and 70 rpm. The result of this research comparing washing the galangal by farmers and a machine found that the operating capacity was 33.22 and 122.5 kg/h, the washing efficiency was 90.95% and 35.78%, and the percentage of damage was 0.08% and 1.09%, respectively. In the future, improvements should be made to increase the washing efficiency of galangal by increasing the washing time, and a water circulation system should be added to reduce water waste.
