Next, the method for forming a food product according to the first invention will be explained with reference to FIGS. 1 to 6.

First, a predetermined amount of material 7 is put into the extruder 1, the screw 8 is rotated to mix it, and the mixed material 7 is sequentially pushed from the die 9 into the gap X between the support roller 2 and the rotating roller 3. put out. The material 7 is pushed between the inner rollers 2 and 3 while being foamed on the exit side of the die 9.

On the other hand, the honey-hanging device l14 is operated by the tank 1 by the pump 19 started in accordance with the extrusion of the material 7 from the extruder 1.
The honey 20 in 8 is applied in multiple strips from the nozzle 17 onto the feed roller 16 as shown in the figure. The honey 20 flows down from the feed roller 16 onto the filter roller 3, and as the filter roller 3 rotates, it comes into contact with the material 7 and is applied.

The material 7 is formed within the gap X between the edge rollers 2 and 3 coated with the honey 20, and is sent to the overlay material supply device 5 at the next stage. The overlaying material supply device Wt5, like the honeycombing device 4, feeds the overlaying material 2 by the feed conveyor device 21 activated in accordance with the extrusion of the material 7 from the extruder 1.
6 is supplied to the recess 27 of the rotating body 25. The top material 26 that did not enter the recess 27 during supply is transferred to the collection conveyor 2.
3, so the yield does not decrease.

The top material 26 supplied to the recess 27 of the rotating body 25 is
It is drawn by the vacuum in the gap Z through the communication hole 28 and is attracted. Then, as the rotating row 222 rotates, it moves downward, and when the communication hole 28 is blocked by the M-shaped part 29, the overlying material 27 loses its suction force and falls onto the material 7, which is coated in advance. It is glued onto the honey 20 that was previously used. In the case of the top material 26a such as powder, the rotating roller 22a shown in FIG. falling,
It will adhere to material 7.

The material 7 that has been supplied with the top material 26 or 1i26a and adhered to the honey 20 is pushed onto the net conveyor 31 of the transport device 6, roasted in the oven 32, and finally subjected to processing such as cutting. to finish molding.

Next, a case where the cutter A is attached to the rotating roller 22 will be explained. When the rotary roller 22 rotates a predetermined angle (45 degrees in the illustrated example), the material 7 supplied with the overlay material 27 in the same manner as above is cut into pieces of fixed dimensions by the cutter AK, and is then cut into pieces by the next conveying device 6. is sent to the net conveyor 31.

The net conveyor 31 switches the speed of the motor 35 so that the moving speed V of the net 36 is greater than the moving speed V of the material 7 between the support roller 2, the filter roller 3 and the rotating roller 22. For this reason, the cut material 7
are conveyed on the net conveyor 31 with the intervals between them being larger than at the time of cutting. In the open 32, the materials 7 are sent at predetermined intervals, which increases the roasting effect, and prevents the materials 7 from sticking to the net 36 or the roasting being uneven due to overlapping of the materials 7. It also becomes easier to dry and roasted with a constant and stable quality. Incidentally, since the distance between the materials 7 begins to widen at the edges of the cutting ridges, the cutting itself is easily performed.

The foods covered by both the first and second inventions above are:
It has a broad concept that includes not only general foods but also seafood paste products, pet foods, etc.
