The government has budgeted assistance/grants continuously many bed dryers to farmers but many of them were not used because farmers felt that the drying production rate of rice is more expensive than the traditional open sun drying. The farmers choose to go back to the traditional way that takes the drying process longer than using the dryer. For 1 year, open sun drying can process 100 batches, and dryer can process 450 batches. This research tries to solve the high cost problem by looking for a new alternative solution. The solution is replacing the oil burner with a rice husk burner, which is appropriate both economically and environmentally. For the stirring mechanism, this system must continuously stir up the pile of grains during the drying process. The point must be fulfilled is that the total cost of the drying process should not rise, especially the cost of the stirring process. A stirrer mechanism that needs smaller power than the maximum power setting is made. Farmers’ income for this innovative modification will get a 332% increasing profit than using oil burner bed dryer machine and will get a 41% increasing in welfare than using the standard husk burner bed dryer.

Uneven drying is a prominent problem in the performance of Flatbed type grain dryer. An effort to move around the materials during the drying process is needed in order to get a uniformed drying rate. This paper investigates the conditions of an evenly distributed reduction of materials' water content during drying, using a flatbed dryer and a stirring mechanization system. It is found that ≥ 4rpm stirring rotation produces a relatively even drying result after 1 hour, and that there exists a second airflow that leaked due to the stirring process moving around with the motion of the stirrer.
