摘要

The present invention relates to a method of producing chaff charcoal is prepared using chaff as a main raw material, the manufacturing process of the present invention is put into the hopper of the chaff charcoal maker of debris removed foreign matter, and the chaff added to the hopper by water It is ground by grinding 70 ~ 85% of powdered rice oil and rice, and the nozzle is transferred to the screw.The rice husks conveyed to the nozzle are passed through the inner surface of the nozzle with nine rows of indentation grooves. After long heating to 300 ~ 400 ℃ to form a rod shape, and cut the solid molded body into rod shape by cutting with 400mm length, bundle 20 bundles and build them up in a crypt kiln and keep the temperature of charcoal kiln more than 1,000 ℃. When the fire is continued for 7 to 10 days, it is characterized in that it is cooled for 5 to 7 days to produce carbonized rod-shaped chaff charcoal. It is a very innovative fuel in terms of resource recycling because it is the main raw material of chaff that is discarded by composts at each farmhouse, and it is not difficult to purchase raw materials compared to conventional sawdust charcoal, and you can purchase chaff at a cheap price.
