Abstract

The process of post-harvest handling of rice still has various obstacles, one of which is the process of lowering the water content or drying of rice grain. In the drying process carried out on rice grain, most of it still uses the traditional method. This method is an easy and cheap way, but will be faced with various obstacles, namely during the rainy season so it cannot do the drying, requires a large area of land for the process of drying rice grain, and requires a relatively long time while rice husk can be used as an energy source. heat for the process of drying rice grain using a machine. Based on this, a tool is designed that is useful for the drying process of rice grain using waste fuel from rice grain milling, namely rice husk as the main source of heat energy so that the drying process is not constrained by uncertain weather, and obtains a fast rate of drying of rice grain. The research method was carried out by carrying out the performance of the tool where varying the temperature used for the rice grain drying process so that optimum conditions were obtained based on the use of the machine. The design results obtained are a rice grain drying machine with a capacity of 7-8 tons, and a vertical model/type, as well as a heating source in the form of combustion originating from the husks. This grain drying machine has parts in the form of a drying chamber with dimensions of 2500×2500×6300 mm, an elevator bucket with dimensions of 750×350×7600 mm, dimensions of the suction blower 1000×900×1680 mm, and the size of the suction blower fan has a diameter of 400 mm, while the dimensions rice husk burning kitchen measuring 1300×1600×2500 mm.
