Abstract
The purpose of this study is to develop a paddle-type dryer and to commercialize the dryer, in which mixing and drying can be done simultaneously. According to a performance test, a newly-designed paddle-type dryer can dry Chitosan salt to a low moisture contents below 0.3%. Also the newly-designed dryer can dry air pollution materials, because the dryer can operate in a closed system. The economic efficiency of a newly-designed system and an existing system was compared in a performance test. As a result, the economic efficiency of a newly-designed system was higher than an existing system. In conclusion, it is thought that the newly-designed system has a high commercial value.
