Drying of heat transfer is a process that occurs due to a significant difference in temperature between the two surfaces. The components of the air flow when the drying process include speed, temperature, pressure, and humidity. However, in its original condition, found several problems, one of which is the uneven distribution of heat on the dryers are used. At the time of the study has several objectives, namely do research the optimum heat distribution in space as an alternative to charcoal briquette dryers drying and conduct testing using CFD to analyze the distribution of heat in the space of dryer. Charcoal briquette dryers System Tray Drying (drying racks-floor) there are 7 storey arranged shelves for putting wet charcoal briquettes. Determining the drying system is performed to find out the distribution of air temperature in the dryer Inlet and outlet air based on the varied in comparison to get the optimum heat distribution is 60 oC in the dryer. Drying heat sources comes from electric heater air blower driven into the dryer with the help of the flexible pipe. Hot air continues to flow to increase the temperature of the air in the dryer through the process of heat transfer. The test is performed three times on variants 1 and 2. It can be seen that the results of the simulation of various temperature inlet the most optimum value in approaching spaces dryer in Variant 1. This is because the temperature of a molecule is inversely proportional to its mass. The greater the temperature of a molecule, then the density will be getting smaller. Therefore, the required outlet hole at the top. Optimum value approach results in Variant 1. The results of the average temperature of the rack with a maximum value of 56.43 oC inlet temperature 100 oC. Design Variant 1 is the most excellent design than the Variant 2, because the value of the temperature of the rack 1 to 5 approaching the optimum results. There is excess temperature in the rack 6 to 7 but not too far, namely 61.19 to 62.48 oC.
