This research aims to construct a hot air control system prototype to dry raw bricks before entering the biomass combustion process. The researchers designed and created the system for repelling moisture by using a hot air generator which included a biomass furnace, a hot air suction cabinet which transferring heat to 1 hp 17 w/s fan, and finally a 4 × 9 × 1.8 m.3 heat accumulation room. The system was then tested for expelling moisture with three different types of raw brick arrangements at 40 °C, 50 °C and 65 °C. It was found that the arrangement of raw brick with pillar at 65 °C for 8 hours can reduce moisture of 3,300 bricks by 4.20 percent and the average speed of drying varied according to the rising temperatures. As a result, the hot air control system prototype with biomass energy can reduce the time for expelling moisture from raw brick more efficiently than the original process which used at least 30 percent of natural energy in the building. The return of investment was 80 days.
