“…In drying agricultural products, several important parameters that need to be considered are expressed by [5], [7], [8] which states that the humidity in the media or drying chamber affects the speed of the drying process of agricultural products, while [8] state that drying time depending on the thickness of the material being dried.…”

In many cases, tobacco leaves are still dried using conventional methods, which relies merely on sunlight, thus making it difficult for farmers to dry them in the rainy season. Tobacco leaves rot easily, so alternative drying methods that are not weather dependent are required. Our research offers a solution by making a tobacco leaf drying machine with a refrigeration system. This tool can accommodate 5 kg of tobacco and can be controlled by a PLC and monitored using SCADA. The drying test was carried out at a temperature setting of 40°C-50°C and a humidity of around 25%-55%. The first test was drying 1 kg of tobacco leaves with a moisture content of 30%, which required a drying time of up to 2 hours and 40 minutes. After the drying process, the average weight of tobacco leaves became 287.8 g with a moisture content of 12%. The second test was the drying of 5 kg of tobacco leaves with a moisture content of 30%, which required a drying time of up to 4 hours and 15 minutes. After the drying process, the weight of the tobacco leaves was 880 g and the moisture content was 11.5%. The test results show that tobacco leaves can be dried without changing their original color and shape, even though they had experienced a decrease in mass and water content.

“…Delay in drying, incomplete drying, or ineffective drying will reduce leaf quality, and result in losses [8]. The design and development of this tool are beneficial in reducing dependence on cloudy weather conditions for harvesting and drying processes which in turn allows farmers to spend more time on other post-harvest activities [9]. Several conventional methods for leaf drying include solar bubble drying, layer drying, natural low-temperature airflow drying, and continuous airflow drying [9].…”

“…The aluminium gauze is perfect for laying Moringa leaves comfortably and also for proper hot air penetration [10]. This research architecture has never been used on Moringa leaf objects based on article reviews [9], [14]. It uses Arduino/Atmega microcontroller for intelligent control actions that need to be implemented for the drying process [15]- [17].…”

This paper presents the design and development of an automatic dual energy solar powered Moringa dryer used to remove moisture. Moringa leaves are circulated by hot air evenly in a cylindrical mesh of aluminum mesh which rotates at 20 revolutions per minute through which hot air is passed to extract moisture from the leaves. The Arduino Uno or Atmega32 microcontroller works in conjunction with appropriate sensors to monitor and control humidity, moisture content, motor speed, room temperature, heater, and fan. Based on the moisture content in the Moringa leaves, the sensor sends a control signal to the controller. The results showed a good response in removing the initial moisture content from 18.5% to the final moisture content to 4% of green leaves without changing the nutritional value. Qualitative analysis showed that traditional drying, namely open drying, drying Moringa leaves each for 3 days in 12 hours with a final moisture content of 7%, while double solar drying only takes 3 days in 12 hours with a final moisture content of 4%, and produce better quality Moringa leaves. High efficiency in the drying process of Moringa leaves compared to traditional drying, where this tool can dry Moringa leaves faster by 3%.
