DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food dough division and rounding system for dividing a plurality of divided food doughs into a plurality of divided food doughs (for example, bread dough).

[0002]

2. Description of the Related Art A brief description of a conventional food dough dividing and rounding system is as follows.

That is, the split rounding system is based on a main body frame, and the main body frame is provided with a belt conveyor for conveying highly adhesive food dough. A movable frame is provided above the belt conveyor in the main body frame, and the movable frame is provided with a forming part that forms a plurality of divided food doughs and rounds and forms the plurality of divided food doughs. Here, in performing the round forming, the movable frame is configured to be able to turn under a state of maintaining a fixed direction in order to make the forming portion circularly move.

Therefore, the food dough is conveyed by the belt conveyor and is positioned at a predetermined position. Next, the food dough is divided into a plurality of pieces by the forming section. Then, the movable frame is turned under a state in which the movable frame is held in a fixed direction, and the molded portion is moved circularly. Thereby, each divided food dough can be circularly moved while being pulled on the belt of the belt conveyor, and the peripheral edge of each divided food dough flows to the center of the circular movement due to the adhesion of each divided food dough to the belt. Therefore, each divided food dough can be rounded into a spherical shape.

[0005]

By the way, the characteristics of food dough (including the size of divided food dough and the material properties of food dough) are various, and some of them are easy to curl or hard to curl. Further, the tissue is easily damaged or hardly damaged by the rounding. On the other hand, the radius of the locus of the circular motion of each divided food dough during the rounding is constant. Therefore, if the radius of the locus of the circular motion of each divided food dough is too small compared to the radius corresponding to the characteristics of the food dough, the peripheral edge of the divided food dough will not easily flow to the center of the circular motion, and the food dough will be removed. Cannot be rounded enough,
Also, if the radius of the locus of the circular motion of each divided food dough is too large compared to the radius corresponding to the characteristics of the food dough, the amount of drag of the divided food dough increases, and the tissue of each divided food dough is damaged. Problem.
