The invention relates to a Chinese hamburger preparation system. The system is characterized in that a griddle surface rotating mechanism is arranged at the front end of a support; a batter scrapping mechanism is arranged on the support beside the griddle surface rotating mechanism; a batter supplying mechanism is arranged at any position on the support; a griddle surface automatically rotates, and the batter supplying mechanism automatically conveys batter to the griddle surface; after being automatically positioned, a scraper plate is used for flattening the batter on the griddle surface. According to the Chinese hamburger preparation system, vertical movement and horizontal movement of the scraper plate and a shoveling knife are driven by a stepping motor, so that the control accuracy is high; a piston in a material barrel is driven by the stepping motor, and quantitative battery conveying is achieved; the system is simple in structure, and convenient to mount and maintain; the griddle surface is driven through a belt, so that the noise is low, and the abrasion is small; the griddle surface can be axially and radially fixed through a fixing block and a mounting block on a supporting plate, steady mounting is ensured, and a fixing rod can be adjusted to fit the fixation of the griddle surface with different size; the structures are matched with each other, so that the whole system is convenient, practical, convenient to mount and maintain, and applicable to different users in different conditions.
