Sheeting Line
Full Automatic Steamed Stuffed Bun/Steamed Bread Production Line
The ZL-1608 steamed bun line runs 20,000-60,000 pcs/h, with the pleating and sealing unit at 1,000-7,200 baozi/h and the mantou former at 1,000-12,000 units/h. Piece weight is 30-180 g, cut size 25-120 mm, working width 600-1600 mm. 27.7 kW full line, 380V or 220V, Siemens PLC, 304 stainless steel.
Product Overview
The steamed stuffed bun production line is an automatic baozi making machine for large industrial food factories and central kitchens, built to form stuffed buns, momo and related filled dough products at 20,000–60,000 pieces per hour. The line runs on 304 stainless steel, uses a PLC control system, and is laid out to the buyer’s floor plan with working widths from 600 mm to 1600 mm.
At this capacity, the line replaces manual pleating and sealing crews that cannot hold shape or weight across a shift. Dough sheeting, filling, forming and tray arrangement run in one continuous flow, so a dim sum factory or frozen food plant gets consistent product standardization and a documented food-safety process instead of hand-work variation.
Key Features
- Capacity range of 20,000–60,000 pcs/hour: one line covers a full shift of retail or frozen baozi supply without adding forming staff.
- 304 stainless steel contact surfaces: the line suits daily washdown and food-safety audits in a dim sum or central kitchen plant.
- PLC control with Siemens system: recipe changes and speed settings are made from the panel, not by re-setting mechanical parts.
- Modular build with 270-degree adjustable units: cutters and forming heads can be swapped to run momo, red bean paste buns, milk & egg baozi or jam tart.
- Dough belt forming with encrusting cutter: buns come out with a rounder, consistent shape and small weight error, batch after batch.
- Low-stress dough processing: the sheeting system works the dough gently, so the wrapper keeps its structure and does not tear at the pleats.
- Synchronous speed control: sheeting, filling and forming stay matched, which removes the speed drift that causes over- or under-filled buns.
- Customized floor design: the line is built to the length and width of your building rather than forcing a building around a fixed footprint.

Industrial Applications
- Baozi making machine for dim sum factory: a dim sum plant running momo, red bean paste buns and breakfast baozi needs one line that changes cutters between runs; the modular forming units and multiple cutter sets cover the product range without a second machine.
- Baozi making machine for central kitchen: central kitchens supply many outlets from one site, so output has to be steady through the shift; 20,000–60,000 pcs/hour and PLC control keep the filling weight and shape consistent across the day’s production.
- Baozi making machine for frozen food plant: frozen baozi must survive packing and reheating with an even shape; the dough belt forming and encrusting cutter produce a rounder, consistent bun with small weight error, which reduces rejects at the freezer and packing line.
- Steamed bun forming machine for breakfast baozi: breakfast baozi is a high-volume, low-margin item, so labor cost decides the price; the automatic line replaces manual pleating crews and holds product standardization across early-morning runs.
- Bakery and pastry lines for filled products: the same platform runs jam tart and other filled dough items, which lets a pastry plant use one line across product seasons instead of idling a dedicated machine.
Key Advantages
- The line runs 20,000–60,000 pcs/hour, so a single shift covers volumes that would otherwise need several manual forming tables and the staff to run them.
- Stainless steel construction and PLC control make the process repeatable. Product standardization and food-safety documentation depend on that repeatability.
- Modular units adjust through 270 degrees and accept multiple cutter sets, so a product change is a setup task rather than a new machine purchase.
- Dough belt forming with an encrusting cutter holds shape and weight error small, cutting giveaway on filling and rejects at packing.
- Customized floor design means the line fits the building you have, avoiding civil works and lost floor space.
- Connecting a proofing machine turns the forming line into a full automatic production process from dough to proofed bun.
How to Choose the Right Configuration
| Full automatic line with proofing connection | for large industrial food factories that want dough-to-proofed-bun flow and the lowest labor per piece. |
|---|---|
| Line without proofing connection | for plants that already run a proofing room and only need sheeting, filling and forming. |
| Pleating and sealing machine only | for factories with existing dough preparation, forming 1,000–7,200 baozi/hour. |
| Mantou configuration | for steamed bread producers with no filling, at 1,000–12,000 units/hour. |
| Multi-cutter setup | for dim sum factories running momo, red bean paste buns and jam tart on one line. |
| Narrow working width (600 mm) | for buildings with limited floor space and moderate capacity targets. |
| Wide working width (up to 1600 mm) | for high-capacity plants that need the full 60,000 pcs/hour output. |

Factory Strength
The plant builds the full line in-house: dough sheeting, forming, electrical and PLC assembly, and final testing before packing. A complete line is assembled and run before shipment, so the sheeting, filling and forming stages are proven together rather than on site. The same workshop produces the ZL-1608 bread and pastry line, which shares the modular design and Siemens control platform used on the bun line. Machines ship to export markets, with voltage and floor layout set to the destination plant before build.
Quality Control
Incoming stainless steel and bought-in components are checked against the build sheet before assembly. Each unit is inspected at the forming and electrical stages, and the finished line is run to confirm capacity, shape consistency and weight error before packing. Control panels are tested with the Siemens system loaded. Traceability follows the build sheet for each order.
- Incoming material check on stainless steel and components
