Abstract
Drying process is the key of grain postharvest. Moisture reduction to a safe level for storage was aimed to reduce the microorganism attack. Solar drying has several disadvantages, they are unstable temperature, animal disturbance, unpredictable rainfall and the low capacity. The existance of box dryer has been the correct solution before the rising fosil fuel price. The Th incoming problem was that government decided to change the use of kerosene to liquified petroleom gas (LPG), the kerosene price was gradually increased. The main objective of this research was to set back the rice price to previous price. As a consequence of drying cost many farmers directly sold their paddy rice after threshing process to the broker with low price. These brokers usually have big warehouses equiped with continuous dryers uses electricity as energy source. The furnace was designed to produce heat bring into water and then the air suck the air through the heat exchanger. Rice husk is a kind of agricultural biomass that was still a environmant problem in agricultural area. At top side of the cylinder was installed an ?inch pipa. In front of the blower was a heat exchanger as a tool to send hot air into the plenum chamber. The heat exchanger also functioned to change the water favor into liquid. Then, this water flows back to cylinder, an so fort. The temperature of 40-60?C was reached in the plenum chamber. The average temperature in the combustion chamber was 253?C, temperature in the pipe as 94?C, and 55?C in the plenum chamber. In the research, the the plenum chamber was maintained clean because the heat exchanger and the furnace was separated.
