Output to means 19. The first control means 19 reads filling amount data from the filling amount data storage means 15 based on this first type signal. This filling amount data is based on the baking mold 1 facing the filling means 5.
The content shall be the filling amount of the raw material that matches the above. and,
The first control means 19 controls the filling means 5 based on this filling amount data, and fills the baking mold 1 with the same amount of raw material. This operation is performed every time each baking mold 1 faces the filling means 5.

On the other hand, the second mold recognition means 27 recognizes the type of baking mold 2 facing the heating means 7, and outputs a second mold signal corresponding to the baking mold 2 to the second control means 29.

The second control means 29 reads the heating amount data from the heating amount data storage means 25 based on this second type signal. The content of this heating amount data is the heating amount that matches the baking mold 2 facing the heating means 7. And the second control means 2
9 controls the heating means 7 based on this heating amount data to apply an appropriate amount of heat to the baking mold 2. This operation is performed every time each baking mold 2 faces the heating means 5.

Note that the filling amount and heating amount can be determined for each baking mold and stored in advance in each of the storage means 15 and 25 as filling amount data and heating amount data, respectively.
