Optimization of Corn Drying with Rice Husk Biomass Energy Conversion through heat exchange drying devices

The heat exchanger is used for the conversion process of rice husk biomass energy into thermal energy. This device connects the furnace to the drying chamber. The heat exchanger is made of stainless steel pipes arranged in parallel arrangement. The purpose of using this heat exchanger in the dryer is to avoid contamination of the product with gasses, which are coming from the burning of the husk in the furnace. In the drying chamber, there are fourshelves, which are used to dry the corn seeds. To optimize the heat transfer from the heat exchanger into the drying chamber, redesign of the furnace wall was carried out through variations in the number of holes, namely 144, 252, 360 and 468. The test results of the 4-kg corn seeds drying process in the drying chamber were obtained andmore number of holes are directly proportional to the increase in dryer performance. The drying of corn seeds from the moisture content of 12% to 19% with the shortest time, and the highest drying rate occurred in the variation of the furnace wall with the number of holes equal to 468 that are 58 minutes and 0.092 g/s and the efficiency of the dryer is 28.8%.
