Processing method and device for extrusion of raw materials with enzymes added for production of starch syrup, and saccharogenic method for extruded raw materials

A device for the extrusion of raw materials with enzymes added for production of starch syrup, characterized in that the device basically comprises a whole of an axially bisectable barrel set and a whole of a screw set;

• the whole of the barrel set comprises the first barrel (2), the second barrel (4), the third barrel (5) and the fourth barrel (7), wherein each barrel is axially bisectable and the whole of the barrel set is thus also axially bisectable;
• the first barrel (2), the second barrel (4), the third barrel (5) and the fourth barrel (7) are assembled in the numbering order and can be closed when the device is in operation by locking the upper part and lower part of each of the above-said barrels with fastener (14) and fastener (16), fastener (13) and fastener (17), fastener (12) and fastener (18), fastener (11) and fastener (19) respectively;
• the whole of the screw set comprises the main shaft (15), the first screw (1), the second screw (6) and the third screw (10), wherein each screw is installed enclosing the main shaft (15) in the numbering order and rotates with the main shaft (15);
• after disassembling the die plate (8) and the above-said fasteners, the two bisectable halves of the whole of the barrel set consisting of the corresponding two bisectable halves of the first barrel (2), the second barrel (4), the third barrel (5) and the fourth barrel (7) assembled together can be rotated outward around shaft A and shaft B respectively so that the two bisectable halves of the whole of the barrel set are opened apart from each other;
• the first barrel (2) is not heated or cooled;
• the outer surfaces of the second barrel (4), the third barrel (5) and the fourth barrel (7) are heated by pressurized hot steam or electricity and forcedly cooled by cooling water or air, so that the temperature in the each barrel can be adjusted automatically.
