[0002] As one of the foods people eat daily, bread has been widely favored by people. The production process of bread is usually stirring → fermentation → dividing → rolling → intermediate proofing → molding → proofing → baking → cooling → packaging. In the molding process, the divided dough needs to be shaped into the required shape, and when making sandwich bread, the dough also needs to be filled with fillings.
