Abstract
The Moisture content after harvesting process of Paka-Umpul rice is a problem for storage. This study was designed and built a grate kiln to store the thermal from wood chips. The objective was to evaluate the thermal performance of the grate kiln. The operation started from literature review, designing the grate kiln and testing to dry of Paka-Umpul rice grain to analyzed the ability of thermal accumulation and drying time to reduce the moisture of Paka-Umpul rice. The results showed 10 kilograms of Paka-umpul rice grain and wood chips were burning within 180 minutes while the average inside thermal kiln was at 165 oC. and grate was at 210 oC. Then thermal was transferred to dry room that controlled heat air flow by the control valve. The control temperature set at 45 to 55 oC for 90 minutes that can reduce moisture at average 8% w.b. This result is important to apply for drying the other agriculture products.
