This paper presents the design and development of an automatic dual energysolar powered Moringa dryer used to remove moisture. Moringa leaves arecirculated by hot air evenly in a cylindrical mesh of aluminum mesh whichrotates at 20 revolutions per minute through which hot air is passed toextract moisture from the leaves. The Arduino Uno or Atmega32microcontroller works in conjunction with appropriate sensors to monitorand control humidity, moisture content, motor speed, room temperature,heater, and fan. Based on the moisture content in the Moringa leaves, thesensor sends a control signal to the controller. The results showed a good response in removing the initial moisture content from 18.5% to the finalmoisture content to 4% of green leaves without changing the nutritionalvalue. Qualitative analysis showed that traditional drying, namely opendrying, drying Moringa leaves each for 3 days in 12 hours with a finalmoisture content of 7%, while double solar drying only takes 3 days in12 hours with a final moisture content of 4%, and produce better qualityMoringa leaves. High efficiency in the drying process of Moringa leaves compared to traditional drying, where this tool can dry Moringa leaves fasterby 3%. |
