A dryer (100) includes inner drums (18) and outer cylindrical drums (26) placed concentric to each other, wherein both the drums (18, 26) are perforated and define a space there between. An inlet mechanism (42, 35) is located at a top end of the cylindrical drums (18, 26) for feeding the moisturized material in the space defined between the inner and the outer cylindrical drums (18, 26). A motion imparting means (38) is coupled to the inner cylindrical drum (26) for setting the same in a rotation motion with respect to the outer cylindrical drum (18). An air introducing means (20, 23) is located around the bottom of the inner cylindrical drum (26) for introducing air thereto. Finally, an outlet mechanism (27) is located about a bottom end of the cylindrical drums (26, 18) for withdrawing a dried material. |
