An opening combined with the opening of the extruder 1 is formed at one end of the stationary hollow tube 7 and an opening with a reduced diameter is formed at the other end. The opening having a reduced diameter is reduced compared to, for example, the opening coupled to the opening of the extruder 1. The extrudate forming apparatus 3 will be described in detail with reference to FIG. 2. The cutting device 4 is in communication with a rotating hollow tube 1 3 (see FIG. 2) to be described later, and is configured to form a plurality of numbers 17 312 / Invention (Supplement) / 92- 06/92105595 200305375 Extrudate cutting in strand form. Further, the cutting device 4 is configured to twist the extrudate in the form of a plurality of strands formed through the rotating nozzle 12 and cut it while introducing it. In addition, the cutting blade of the cutting device 4 is rotated in such a manner as to intersect with the rotation direction of the rotating nozzle 12 to be described later. The cutting device 4 is constructed by linearly introducing the extrudate in the form of a plurality of strands into the cutting device 4 to twist them together, and cutting to present a twisted strand shape. As shown in the perspective view of Fig. 3 (a), the stationary mandrel 8 is fixed to the die head part B, and the die part B is disposed adjacent to the extruder 1 and integrated with the stationary hollow pipe 7. A plurality of holes 15 are formed in the fixed portion 14 to allow the food dough prepared by gelation through the extruder i to pass through. At the same time, the fixed part 14 carries and fixes one end of the stationary mandrel 8. More specifically, the static mandrel 8 is fitted to the die part B via the fixing part 14, that is, the opening of the extruder 1. Further, the stationary hollow pipe 7 is installed in such a manner that the die portion B of the extruder 1, that is, the opening of the extruder 1 and the opening of the stationary hollow pipe 7 can be fitted to each other. In addition, as shown in the cross-sectional view along the line X-X in FIG. 3 (b), many holes 15 formed in the fixed portion 14 are close to the periphery of the stationary mandrel 8 at equal distances in the circumferential direction. It is arranged to cooperate with the gap 9 formed between the stationary mandrel 8 and the stationary hollow tube 7. In other words, the food dough extruded through the opening of the extruder 1 will pass through the holes 15 in the fixed portion 14 and will be squeezed into the gap 9. Referring to Fig. 2, the extrudate forming apparatus 3 will be further explained. FIG. 2 is an enlarged cross-sectional view of a portion surrounded by a dotted circle in FIG. 1. FIG. It should be noted that the cross section of the stationary mandrel 8 is not shown in FIG. 2. The stationary mandrel 8 is inserted into the stationary hollow 18 3] 2 / Invention (Supplement) / 92-06 / 92105595 200305375 in the tube 7 'and forms a gap 9 with the stationary hollow tube 7 together. The gap 9 formed between the stationary hollow tube 7 and the stationary mandrel 8 is such that after an area having a constant thickness, in the extrusion direction of the food dough (in the direction of the arrow symbol A in the drawing) It is formed in such a manner that the thickness of the gap 9 is reduced. In this way, the opening adjacent to the reduced diameter of the stationary hollow tube 7 is formed with a narrow gap 10 ° narrower than the gap 9 adjacent to the opening coupled to the extruder 1 In addition, the extrudate forming device 3 includes The rotating nozzles 12 are arranged in a row to be integrally connected with the rotating nozzles 12 and rotate around the rotating hollow tube 13 of the stationary mandrel 8. The stationary mandrel 8 has a terminal portion 18 formed by reducing its diameter. Furthermore, the rotating hollow tube 1 3 is configured to rotate around the terminal portion 18 of the stationary spindle 8 integrated with the rotating nozzle worker 2. Specifically, the rotating nozzle 12 and the rotating hollow tube 13 rotate as a whole around the terminal portion 18 of the stationary mandrel 8 at the same angular velocity. More specifically, the extrudate in the form of a plurality of strands formed through the rotating nozzle 12 is squeezed into the rotating hollow tube 13 and then twisted together. The plurality of recesses 11 in the rotating nozzle 12 are formed in the radial direction of the stationary mandrel 8 and the gaps formed between the openings adjacent to the reduced diameter of the stationary hollow tube 7 are narrower. It should be noted that the number of the recesses 1 1 in the rotary nozzle i 2 corresponds to the number of strands of the extrudate to be described later. In other words, the number of recesses 11 will be determined according to the number of strands of the extrudate to be formed. In addition, the number of the recesses 11 formed in the rotary nozzle 12 is two or more, but preferably sixteen or less.

In this way, an expanded food having an attractive appearance can be produced. Incidentally, unless the number of strands of the extrudate is more than two, the produced expanded food will be monotonous and lack attractiveness. On the other hand, if there are more than 17 strands, when viewing the entire dough, the single strand of the extrudate will be quite thin, and its appearance may appear to be a single strand without attractiveness. Therefore, if the number of strands of the aforementioned extrudate is provided, an expanded food having an attractive appearance can be produced.

The raw material supplied to the extruder 1 is pressurized, kneaded, and cut by a screw 26 in the barrel 25 to form a gelatinized food dough and extruded from the opening. The expanded food manufacturing apparatus 100 squeezes the food dough prepared by gelling with an extruder i into a gap 9 provided between the stationary hollow tube 7 and the stationary mandrel 8. In the expanded food manufacturing apparatus 100, the food dough squeezed into the gap 9 is gradually reduced in thickness after maintaining a constant thickness (S7). To further explain, the thickness of the food dough is gradually reduced by the caliber in the extrusion direction of the food dough (the direction of the arrow symbol A in FIG. 2) only by the stationary hollow tube 7 or the combination with the stationary mandrel 8. The small narrow gap is reduced by 10. By maintaining the food dough at a constant thickness, the food dough can be homogenized. However, a constant thickness' may be maintained only in a short section or the thickness may be gradually reduced without maintaining a constant thickness. Then, in the expanded food manufacturing apparatus 100, the reduced-thickness food dough is formed into a plurality of continuous strand-shaped extrudates (S9).

The expanded food manufacturing apparatus 10 Q then twists the extrudate in the form of a plurality of continuous strands (S 1 1). The extrudate in the form of a plurality of continuous strands thus formed is extruded into the rotating hollow tube 13 and is twisted and cut when it is introduced into the cutting device 4 (S 1 3). The cut extrudate is then dried (S 1 5). The cutting blade of the cutting device 4 rotates and intersects with the direction of rotation of the rotating hollow tube 13. The extrudate in the form of a plurality of strands is twisted together by being introduced into the cutting device 4 in a straight line, and after cutting, the strands are in the form of twisted strands. The cutting device 4 twists the extrudate in the form of a plurality of continuous strands by rotating the hollow tube 13 and cuts the extrudate to a desired length at the same time. The freshly cut expanded food has a water content of 8 to 15 weight percent, preferably 10 to 12 weight percent, and its water content will be dried to 3 to 0. 1 weight percent to 2 to 0. 5 weight percent is preferred.
