Thermal characteristics of the dryer with rice husk double furnace - heat exchanger for smallholder scale drying

Smallholder farmer scale drying is very dependent on sunlight because of limited costs and technology. The downside is when the weather is erratic due to weather changes. In addition, the temperature is less than optimal which affects the time and quality of the dried product. The study aims to dete...

description Smallholder farmer scale drying is very dependent on sunlight because of limited costs and technology. The downside is when the weather is erratic due to weather changes. In addition, the temperature is less than optimal which affects the time and quality of the dried product. The study aims to determine the thermal characteristics of the dryer design in the application of appropriate technology through the use of rice husks. The dryer is designed to use two furnaces in which heat exchanger pipes are added. The distribution of heat through the heat exchanger pipes and conduction from the furnace attached to the wall of the drying chamber. The test results show that the average ambient air temperature of 32.14oC can be increased to 92.10oC, 93.27oC, and 94.96oC in the drying chamber for variations in the diameter of the furnace wall holes of 8 mm, 10 mm, and 12 mm, respectively. Sequentially, the temperature in the drying chamber reaches a maximum of 119.13oC, 127.98oC, and 140.89oC. This dryer model is expected to be a solution for small farmers in a sustainable and energy-efficient post-harvest drying process.
