[Confectionery manufacturing process]
Next, the flow of the confectionery manufacturing process in the confectionery manufacturing system shown in FIG. 1 will be described. Here, one mixer 2 and the operation corresponding to it will be described, but the other mixer 2 and the operation corresponding thereto are the same.

  First, the semi-finished product before seasoning is supplied from the supply device 7 through the supply feeder 8 to the measuring device 3 of the seasoning device. The control device 100 stops the driving of the supply feeder 8 so that the semi-finished product supplied to the measuring instrument 3 becomes the semi-finished product target supply amount, and ends the supply of the semi-finished product to the measuring instrument 3. Thereafter, the discharge gate 32 of the measuring instrument 3 is opened, and the semi-finished product is supplied from the measuring instrument 3 to the mixer 2 (ST1) at the stop position ST1 in which the opening 2a is directed obliquely upward.

  The control device 100 should supply the seasoning supply device 4 based on the weight of the semi-finished product measured in the measuring device 3 when the supply of the semi-finished product from the supply feeder 8 to the measuring device 3 is completed. Find the target supply of seasonings. For example, the target supply amount of the seasoning is calculated by multiplying the weight of the semi-finished product by a predetermined addition rate.

  Then, after the semi-finished product is supplied from the measuring device 3 to the mixer 2, the rotation of the mixer 2 is started, and the seasoning supply device 4 moves forward so that the front portion of the screw feeder 43 is inserted into the mixer 2. Then, the seasoning is supplied to the mixer 2. In this way, after the supply of the semi-finished product from the measuring instrument 3 to the mixer 2 is completed, the mixer 2 is started to rotate, whereby the stirring of the semi-finished product and the supplied seasoning is started. When the supply of the target amount of seasoning is completed, the seasoning supply device 4 is retracted and the screw feeder 43 is retracted to the outside of the mixer 2.

  Then, in the mixer 2 to which the semi-finished product and the seasoning are supplied, the turntable 1 is next rotated 1/4 to stop position ST2, and then the turntable 1 is rotated 1/4 to stop position ST3. . Further, the turntable 1 is rotated by 1/4, and the stop position ST4 is reached. The stop time at each stop position ST1 to ST4 is set equal.

  Further, at the stop positions ST2 to ST4, stirring of the semi-finished product and the seasoning by the rotation of the mixer 2 is continued. Then, after completing the rotation of the mixer 2 at the stop position ST4, the mixer 2 is tilted so that the opening 2a faces downward, and the seasoned semi-finished product is discharged onto the discharge conveyor 9. Thereafter, the turntable 1 is rotated 1/4 and returns to the stop position ST1. At that time, during rotation of the turntable 1, the mixer 2 is tilted so that the opening 2a is directed obliquely upward. Thereafter, the same operation is repeated.

  The semi-finished product discharged from the mixer 2 at the stop position ST4 to the discharge conveyor 9 is further slid down the chute 10 and supplied to the supply device 11 for the combination weighing device 12. The semi-finished products supplied from the supply device 11 to the combination weighing device 12 are combined and weighed by the combination weighing device 12, and the semi-finished products having a weight within a predetermined weight range are collectively discharged as a lump into the packaging machine 13. The packaging machine 13 is disposed below the combination weighing device 12 and packs and packs a batch of semi-finished products sequentially discharged from the combination weighing device 12 while sequentially manufacturing the bags. This results in a seasoned and packaged confectionery product.

[Detailed configuration of seasoning supply device]
Next, the detail of the structure of the seasoning supply apparatus 4 of the example of 1 structure of embodiment of this invention is demonstrated. FIG. 2 is a schematic side view of the seasoning supply device 4 as viewed from the side, and is shown in partial cross section.
