Next, the process of forming the candy 6 on the food material 5 by the candy forming apparatus 1 will be described. Here, the state of the wrinkle forming apparatus 1 shown in FIG. 2 will be described as an initial state or an initial position. The wrinkle forming apparatus 1 adjusts the vertical position of the wrinkle forming apparatus 1 by operating the adjustment knob 17 so as to correspond to the size and height of the food material 5 to be manufactured. The rod 22R of the elevating actuator 22 retracts toward the main body side, and the elevating plate 23 stands by at the raised position. The rod 41R of the actuator 41 advances downward and the lifting rod 35 stands by at the lowered position. At this time, the blade portion 33 of the ridge forming plate 33 rises and stands apart from each other. This operation is referred to as an opening operation of the ridge forming plate 33, and this state is referred to as an open state of the ridge forming plate 33. Further, the rod 51R of the actuator 51 advances upward, and the middle pawl 47 stands by at the raised position. Then, the rotary shaft 49R of the rotary actuator 49 stands by at the initial position.

The food material 5 is conveyed below the wrinkle forming apparatus 1 by the conveyor 9 and is temporarily stopped and positioned. The entire wrinkle forming apparatus 1 is lowered by driving the elevating actuator 22. That is, the pressing member 27, the heel forming plate 33, and the middle claw 47 descend so as to approach the food material 5 while maintaining their positions. Then, the curved concave portion 27A of the pressing member 27 approaches the upper surface of the food material 5 and covers the food material 5 (see FIG. 3). At this time, a part of the curved surface (inner surface) of the recess 27A may be in contact with a part of the upper surface of the food material 5, and the interval between the recess 27A and the upper surface of the food material 5 is initially set. It depends on the position setting and can be adjusted arbitrarily.

The blade portion 33C of the flange forming plate 33 descends, enters the recess 27A through the slit 27C of the pressing member 27, and gathers toward the center (see FIG. 8a). This operation is referred to as a closing operation of the ridge forming plate 33, and this state is referred to as a closed state of the ridge forming plate 33. Each blade 33D bites into the dough 5A from the side to the top of the food material 5 (see FIG. 4).

In addition, when the blade portion 33C of the ridge forming plate 33 gathers at the center, the dough 5A between the adjacent blades 33D is raised toward the outside of the food material 5 as the blade 33D bites into the dough 5A. To do. FIG. 9 a schematically shows the cloth 5 </ b> A between the adjacent ridge forming plates 33 in a horizontal section. The protruding fabric 5 </ b> A is pressed from the outside by coming into contact with the recess 27 </ b> A of the pressing member 27. Accordingly, the dough 5 </ b> A of the food material 5 is pressed in a state surrounded by the adjacent blade 33 </ b> D and the dough holding member 27, and 24 ridges 6 are formed on the upper surface of the food material 5. The ridge 6 is formed with a ridge line 6B between the groove 6A formed by the biting of the blade 33D and the surface portion of the raised fabric 5A, so that a clear ridge pattern can be formed (see FIG. 9a). Moreover, wrinkles can be reliably left in the final product.

As the actuator 41 is driven, the elevating rod 35 is lowered, and accordingly, the blade portion 33C of the flange forming plate 33 swings upward, and the blade 33D is retracted from the recess 27A and returned to the open state. At this time, since the food material 5 is covered and pressed by the pressing member 27, the food material 5 is prevented from being displaced on the upper surface (transport surface) of the transport belt 10 even when the dough 5A adheres to the blade 33D. it can.

The lower end portion of the claw member 47 </ b> B of the middle claw 47 is inserted into a place eccentric from the center of the food material 5 at the top portion 5 </ b> C of the food material 5. Then, the middle pawl support shaft 45 is rotated in a required range, for example, 270 degrees by the rotational drive of the rotary actuator 49. The claw member 47B is eccentrically rotated in the dough 5A of the food material 5 and is rotated into the recess 5B by rotating the dough 5A of the top 5C, and the 24 ridges 6 formed in the radial direction are twisted from the top side. As a result, a twist candy 6 similar to handmade is formed on top of the food material 5 (see FIG. 5). It should be noted that the timing of lowering the middle pawl 47 is not limited to the timing described above as long as it is from when the pressing member 27 starts to lower until the heel forming plate 33 returns to the open state.

And the whole wrinkle forming apparatus 1 raises by the drive of the raising / lowering actuator 22. FIG. At this time, by raising the middle nail 47 while rotating, the dough 5A adheres to the middle nail 47 and is pulled upward, and a protrusion 5D is formed on the top 5C of the food material 5. Then, the intermediate pawl support shaft 45 and the intermediate pawl 47 are raised to the initial position by driving the actuator 51, and the intermediate pawl 47 is returned to the initial position by the rotational drive of the rotary actuator 49 (see FIG. 6). And the food material 5 in which the twisted wrinkle pattern was formed is conveyed downstream by the conveyance conveyor, and the next new food material 5 is conveyed from the upstream side.

In addition, it is possible to change the shape of the top part 5C of the food material 5 by adjusting the timing of the rotation operation of the middle claw 47 and the raising operation thereof. For example, the food material 5 shown in FIG. 7a raises the middle nail 47 while rotating the middle nail 47 as described above, and a protrusion 5D is formed on the top 5C of the food material 5. Further, when the middle nail 47 is raised after the rotation of the middle nail 47 is finished, a recess 5B is formed in the top 5C of the food material 5 as shown in FIG. 7b.

Further, the middle claw 47 is not limited to one plate-like claw member 47B, two rod-like claw members 47C, or a claw member 147D having a narrowed tip, for example, a cross-shaped character on the center line CL of the base 4A. It may be a plate-like member that intersects, and can be arbitrarily selected to adjust the pattern formed on the top 5C of the food material 5 and the action of twisting the formed wrinkles.

In the above description, the structure having the middle claws 47 and 147 has been described. However, the middle claws 47 and 147 may not be used. FIG. 7 c shows the food material 5 formed without using the middle nail 47 in the wrinkle forming apparatus 1. On the upper surface of the food material 5, ridges 6 are formed in the radial direction, but by forming the ridge line 6 </ b> B, a clear ridge pattern can be obtained compared to the conventional case. Similarly, the food material 5 molded by the cocoon forming apparatus 91 can also have a clear cocoon pattern as compared with the conventional case.

Further, in the above description, the blades 33D and 33E of the ridge forming plate 33 are configured so as to be able to approach and separate from each other. However, the present invention is not limited to this, and the blades can be reciprocated in the horizontal direction. As such a configuration, for example, a pin integrally attached to the molding plate can be freely moved in a guide hole provided in the guide plate such as a driving mechanism of the molding plate described in JP-A-3-72268. There is a mechanism for reciprocating the molded plate along the long hole of the outer frame by engaging with and rotating the guide plate.

Further, the means for conveying the food material 5 is not limited to a belt conveyor, and may be a conveying means such as a turntable. It is effective in the case. Further, as an elevating means for relatively approaching and separating the food material 5 and the pressing member 27, the upper side of the food material 5 can be lifted even if the support side on which the food material 5 is placed is raised and lowered without raising and lowering the basket forming device 1. Can be covered with the concave portion 27 </ b> A of the pressing member 27.
