The honey 20 in the tank 18 is applied in multiple strips from the nozzle 17 onto the feed roller 16 as shown in the figure by the pump 19 activated in accordance with the extrusion. The honey 20 flows down from the feed roller 16 onto the filter roller 3, contacts the material 7 as the filter roller 3 rotates, and is applied.

After the material 7 is coated with honey 20, both rollers 2 and 3
It is molded within the gap X between them and is sent to the overlay material supply device 5 of the next stage. Top material supply device 5
Similar to the honeycombing device 4, the top material 26 is transferred to the rotating body 25 by the feed conveyor device 21 which is activated in accordance with the extrusion of the material 7 from the extruder 1.
is supplied to the recess 27 of. The top material 26 that did not enter the recess 27 during supply is transferred to the collection conveyor 23.
Since it is recovered by the process, the yield will not be reduced.

The overlaying material 26 supplied to the recess 27 of the rotating body 25 is attracted by the vacuum in the gap Z through the communication hole 28 and is attracted thereto. Then, as the rotating roller 22 rotates, it moves downward, and when the communication hole 28 is blocked by the fan-shaped part 29, the overlying material 26 loses its suction force and falls onto the material 7, and the material 7 that has been previously applied is removed. It is glued onto the honey 20. Overlay material 26a such as powder
In this case, the rotating roller 22a shown in FIG. 4 is used, but in this case, the top material 27a stored in the recess 27 falls at a position where the guard 30 is not attached and adheres to the material 7. It turns out.

When the rotating roller 22 rotates by a predetermined angle (45 degrees in the illustrated example), the material 7 supplied with the overlaying material 26 is cut into pieces of fixed dimensions by the cutter A.
It is sent to the net conveyor 31 of the next stage transport device 6, and then roasted in the oven 32.

In the net conveyor 31, the speed of the motor 35 is changed 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. Therefore, the distance between the cut materials 7 is larger than that at the time of cutting, and the cut materials 7 are placed on the net conveyor 3.
1. And in oven 32, material 7
The roasting effect is enhanced because the ingredients 7 are sent at predetermined intervals, and there is no possibility that the ingredients 7 will stick to the net 36 or that the roasting will be uneven due to the ingredients 7 overlapping each other. It is also easier to dry and roasted with a constant and stable quality.
In addition, since the distance between the materials 7 begins to widen immediately after cutting, the cutting itself can be easily performed.

The foods covered by the first and second inventions have a broad concept that includes not only general foods but also fish paste products, pet foods, and the like.
