It is sent to the dough ball dividing unit 5 through the line 0. The chunk-shaped dough D3 is a substantially rectangular parallelepiped chunk (thick cut dough) having a constant width and thickness and a constant weight. Each can obtain a uniform dodge dough.

In the dough ball dividing section 5, the chunk-shaped dough D3 is divided into small balls of a predetermined size, further rounded and discharged to a downstream process. Dough ball measuring part 5
Then, the weight of the dough of the divided group that has become small is measured. The dough balls of this divided group are conveyed to the dough ball transfer section 6, and are transferred so as to be continuously conveyed downstream.

When the dough obtained in this way is baked, a uniform dough, fine grain and fine texture can be obtained. If conventional divider oil is used, the resulting internal phase of the baked bread will be uneven and large bubbles will remain, or the batter of the dough mixed with this oil will turn into black particles, causing foreign matter to form. To reduce the quality of the product,
By using water instead of this oil, it is possible to remove the adverse effect of the oil on the dough. In addition, the shelf life of the bread itself can be improved as compared with the related art.
