Processing method and device for extrusion of beer adjunct with or without enzymes added, and saccharogenic method for extruded beer adjunct

A device for the extrusion of beer adjunct with or without enzymes added, characterized in that said device substantially comprises a whole of an axially bisectable barrel set and a whole of a screw set;

• the whole of the barrel set comprises a first barrel (2), a second barrel (4), a third barrel (5) and a 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 by locking an upper part and a lower part of each of the above-said barrels with fasteners;
• the whole of the screw set comprises a main shaft (15), a first screw (1), a second screw (6) and a third screw (10), wherein each screw is installed enclosing the main shaft (15) in the numbering order and rotates with the main shaft (15);
• 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 outwardedly around shaft A and shaft B respectively, so that the two bisectable halves of the barrel set are opened apart from each other;
• the whole of the screw set has a length-diameter ratio of 5-20 and a compression ratio of 5-35;
• the first screw (1), the second screw (6) and the third screw (10) enclosing the main shaft (15) have external threads in the opposite rotational direction to a continuous internal thread on the inner surface of the second barrel (4), the third barrel (5) and the fourth barrel (7);
• the external threads of the second screw (6) and the third screw (10) have a helix angle equal approximately to the helix angle of the continuous internal thread on the inner surface of the second barrel (4), the third barrel (5) and the fourth barrel (7);
• a volume between an end surface of a small end of the third screw (10) and an internal surface of die plate (8) being 0.3 to 7 times the theoretical output volume produced when the small end of the third screw (10) rotates one revolution;
• a die nozzle (9) of the die plate (8) has an adjustable diameter ranging from φ3 mm to φ18 mm and an adjustable length ranging from 5 mm to 25 mm.
