PURPOSE: An air tube chamber structure of a fluidized bed dryer is provided to enable to be extended vertically by the curved surfaces of both sides of an air tube when air is supplied to a hollow core of the air tube and the air tube is expanded. CONSTITUTION: An air tube chamber structure of a fluidized bed dryer includes an air tube chamber (500). A hollow core (550) which is surrounded with both lateral walls and top and bottom surfaces is formed. When air is supplied into the hollow core, an air tube chamber is vertically inflated. The both lateral walls of the air tube chamber are formed into curved surfaces (511) which are inwardly curved. The curved surfaces are symmetric. |
