The main function of a bread maker is to use ingredients such as flour and rice, as well as other auxiliary materials, to make various types of bread. The flavor of bread varies depending on the ingredients used. The bread made by the toaster is mainly divided into ordinary bread, French bread, whole wheat or coarse grain bread, Hefeng bread, sweet bread, Mantou, Steamed rolls, etc. The bread made by different brands of bread machines varies.

The bread machine has an oven, a parallel separated kneading cylinder set inside the oven, and a cylinder drive component that rotates one of the kneading cylinders clockwise and counterclockwise. The connecting shaft extends eccentrically from the kneading cylinder and rotates around the rotation axis of each corresponding kneading cylinder. The connecting rod connects the connecting shaft and transmits rotation between the kneading cylinders.
