Zusammenfassung:	The set contains a starch modifying pan, a double-lift combination of 75 double-screws/ 180 single screws, and a sheet die. It can be remotely operated with a PLC or PCC controlling system. It is characterized in that: (1) the starch modifying pan; (2) air-cooled granulation; (3) the sheet being extruded from the die; (4) three-roll calendering traction; (5) two-station wrap-up. The merit is that the starch modifying pan modifies rapidly. The extrusion is 75/ 180 double-lift mixing-smelting extrusion (no need of a liquid pump). Providing a die and three-roll calendering traction. And it shortens then process flow, and adopts a 'low-temperature and high-shear'.
