A mantou (steamed bun) production line is an automated processing system that integrates processes such as dough mixing, continuous sheeting, rolling, extrusion, quantitative cutting, shaping, proofing, and steaming. Its core components typically include units for mixing, sheeting, shaping, proofing, and steaming. Specific configurations and compositions vary depending on production scale, product type, and the level of automation.
A basic mantou production line typically comprises core equipment such as a dough mixer, dough sheeter, mantou forming machine, bun rounding/smoothing machine, steaming cabinet, and steaming trolley.
A fully automatic, multifunctional dough product line can produce items such as mantou, baozi (filled buns), flower rolls, flatbreads, naan, and bread. The equipment includes an automatic flour dusting system, fully automatic dough mixer, conveyors, a main forming unit, a tray-loading machine, a tray conveyor, a tunnel oven or proofing tunnel, a proofing room, and a steaming room. Constructed from materials that meet food processing standards, the equipment is suitable for settings such as central kitchens and food factories.
Small-scale round mantou production lines primarily consist of an integrated dough mixing and conveying unit, a mantou forming machine, and a shaping/smoothing machine; these are suitable for small-to-medium capacity processing plants and workshops. Fully automatic round mantou lines typically include a fully automatic dough mixer, a conveying and dividing machine, a fully automatic continuous dough sheeter, an integrated mantou machine, an alignment unit, and a tray-loading machine, capable of producing 100–150 mantou per minute.
Dual-track production lines for square and round mantou utilize automated control technology to execute processes such as automatic mixing, continuous sheeting, rolling, extrusion, quantitative cutting, and shaping. Materials in contact with food comply with national food hygiene standards, making the system suitable for large-scale production environments like central kitchens and major food enterprises. This type of line can produce round mantou, square mantou, oil-layered rolls, and similar products.
