- Can connect to freezing and packing for frozen bun products
Short answer: A steamed bun production line mixes and rests the dough, divides or wraps it into buns, proofs them under controlled warmth and humidity, then steams them. Whether you make plain mantou or filled baozi, and how the finished bun is sold (fresh, chilled or frozen), decide which forming machine and which back end you need.
How it works
- Mixing – flour, water, yeast and other ingredients are mixed to a smooth dough, then sheeted or rested.
- Dividing or filling – for plain buns the dough is divided and rounded; for filled buns a forming machine wraps a measured filling and closes the top.
- Proofing – buns rest in a warm, humid proofer until they reach the right volume.
- Steaming – a steam cabinet or continuous steam tunnel cooks the buns.
- Cooling – buns are cooled before packing to avoid condensation and sticking.
- Freezing and packing – frozen products pass a quick freezer before packing; fresh products go to packing directly.
Which configuration fits
| Form | Suits | Watch out for |
|---|---|---|
| Mantou rounding | Plain buns, high volume, simple recipe | Even rounding needs stable dough consistency |
| Filled bun forming | Baozi with meat, vegetable or sweet fillings | Filling texture and share limit closing quality |
| Continuous proofing and steaming | Steady output of one or two products | Long equipment footprint; proof time fixes belt length |
Rack-based proofers and steam cabinets cost less and handle many products, but need more labour to move trays. A continuous proofer and steamer suits plants running long shifts on a few products. The proofing time in your recipe directly sets the length of a continuous proofer, which is why we ask for it early.

Where it sits in a line
Dough comes from a vacuum dough mixer; filling from an industrial meat grinder or vegetable cutting machine. Steam can be supplied by a food steam generator. Frozen buns continue to a food freezer and then packing; a food vacuum cooler is one option for fast cooling after steaming.
Common configurations
- Option A
Mantou rounding
dough is divided and rounded or cut into plain buns, the simplest route for high volume.
- Option B
Filled bun forming
a forming machine wraps filling and closes the top with pleats or a twist, for baozi-type products.
- Option C
Continuous proofing and steaming
buns travel through a proofer and steam tunnel on a belt instead of racks, reducing handling.

Frequently asked questions
Can one line make plain and filled buns?
The mixing, proofing and steaming sections can be shared. Plain buns and filled buns use different forming machines, so the line is usually planned with both formers feeding the same proofer and steamer.
Why do our buns shrink or wrinkle after steaming?
Common causes are under- or over-proofing, too-fast cooling after steaming and uneven steam. These depend on the recipe as much as the machines, so we ask for your current process before sizing the proofer and steamer.
Do we need a freezer for steamed buns?
Only if the buns are sold frozen. Fresh and chilled buns need cooling and packing; frozen buns add a quick freezer after cooling.
