무중력 유동층 건조기 개발과 성능평가

초록

The purpose of this study is to develop a new type dryer, which is to proceed mixing and drying of wet-materials at the same time and drying process is carried out in a closed system. In this drying system, thermal contact occurs, when a fluidized zone is created by paddle mechanism. Accordingly, wet-materials is dried in a short time without any damage. Also wet-materials could be dried uniformly to low mosture contents. It is suitable to dry a small quantity of multi-kind materials. And drying process is carried out in a closed system, so as for environmental pollution dust not to be emitted into the atmosphere. Accordingly, it could be used to dry not only food and chemical materials, but also environmental pollution materials.
