Semi-Auto Bun Divider Rounder — Floor-Standing, 10 to 36 Pieces per Cycle

The RMG-S series is a floor-standing semi automatic dough divider rounder covering 20g dinner rolls through 300g large buns. It is built for chain bakery back kitchens, hotel production, and high-volume food service operations where daily output is consistent and reliability matters more than operator-free automation. All five share the same 800 × 610mm footprint and run on either 220V or 380V supply.

Selecting the Right Model for Your Dough Size

Each semi automatic dough divider rounder model in this series covers a fixed weight band — the mold determines the output size — so the primary decision is which weight band matches your main product.

• RMG-10S (200–300g): For large bread rolls, individual sourdough portions, and substantial bun formats like brioche or pandesal. Ten pieces per press is a deliberate choice for dough this size — the machine works the full portion weight properly without rushing the rounding action.
• RMG-16S (100–200g): Burger buns, ciabatta rolls, and medium dinner rolls. The 100–200g range is the single most common commercial bun weight bracket — this is the workhorse model for most food service back kitchens.
• RMG-26S (50–140g): Slider buns, small bread rolls, and lighter brioche. Suitable for hotel breakfast buffets and sandwich chains where portion control at a smaller weight is consistent daily.
• RMG-30S (30–100g): Small dinner rolls and soft roll varieties. Thirty pieces per cycle means a full sheet tray in one press for most pan configurations.
• RMG-36S (20–70g): High-count small roll production — dinner rolls, parker house rolls, small sweet buns. Thirty-six pieces per cycle gives high output per operator hour for operations focused on this size range.

How Semi-Auto Operation Works

The operator loads a pre-scaled dough mass into the machine and manually activates the press cycle — either by pressing a button or pulling the operating lever depending on the configuration. The semi automatic dough divider rounder then completes the divide-and-round cycle automatically: the dough is portioned into equal pieces and each piece is rounded in a single stroke.

This is not continuous automation — the operator initiates each cycle and reloads between batches. For most commercial bun operations, this rhythm works well with a semi automatic dough divider rounder: load, press, remove the tray, reload. A single operator can run the machine while managing proofing trays and other kitchen tasks in parallel.

The semi-auto format keeps initial cost lower than fully automatic models while delivering consistent portion size and rounded ball shape that hand-cutting cannot match at volume.

Built for Daily Production Cycles

At 310kg, this semi automatic dough divider rounder is built to stay in place and run every day. The weight reflects the machine’s structural integrity — the frame does not flex under the press force, which keeps portion consistency stable over tens of thousands of cycles.

Dual voltage supply: 220V/50Hz and 380V/50Hz options cover both single-phase commercial supply and three-phase industrial supply. This matters for international buyers: a hotel kitchen in Southeast Asia may run single-phase, while a factory-scale bread plant in the same region runs three-phase. The same machine specification ships to both.

Low power draw: 0.75KW is modest for a machine this size. Running costs over a full shift are minimal relative to the labor hours it replaces.

Consistent output quality: Semi-auto machines produce rounder, tighter dough balls than hand-rolling at equivalent speed. Tight rounding creates better surface tension, which supports a more even proof and a better oven spring. For operators where finished bun appearance matters — hotel dining, retail bakeries, branded chains — this shows in the final product.

Application Scenarios

Chain bakery central supply kitchens

A central kitchen supplying multiple outlets needs consistent piece weight across all batches — one bakery’s rolls cannot be noticeably larger or smaller than another’s. The RMG-S series delivers the same output weight on every cycle, every day.

Hotel and institutional food service

Hotels running daily breakfast service bake hundreds to low thousands of rolls per shift. The semi-auto series handles this comfortably; the floor-standing format fits into a dedicated dough station without taking up more space than necessary.

Hamburger and sandwich chain back kitchens

The RMG-16S (100–200g) is a direct fit for standard burger bun production at chain restaurants. Consistent bun size means consistent bake time and consistent sandwich assembly across all locations.

Commissary and wholesale bakers

Wholesale bakeries supplying restaurants, cafés, and retail chains need reliable daily throughput without full automation. A semi automatic dough divider rounder gives them the consistency of automation while keeping machine cost and complexity at a level that suits most wholesale operations.

Semi-Auto vs. Fully Automatic — Key Differences

Both series cover the same 10/16/26/30/36 piece configurations and the same dough weight ranges. The differences come down to automation level, power, and price point.

The semi-auto RMG-S requires operator activation of each press cycle. The fully automatic dough divider rounder (RMG-A) completes the cycle independently after initial dough loading — no lever, no button press between batches. For operations where the machine operator is also handling other tasks and cannot dedicate full attention to the divider, the fully automatic model reduces operator dependency.

Power is also different: the semi-auto runs at 0.75KW vs. 1.5KW for the fully automatic. The fully automatic machine is heavier (485kg vs. 310kg) and higher capital cost. For daily volumes below around 1,000 pieces per shift, semi-auto is the more efficient investment.

الأسئلة المتكررة

How does a semi automatic dough divider rounder compare to a fully automatic one?

Semi-auto requires the operator to manually activate each press cycle — load the dough, press, remove the pieces, repeat. Fully automatic completes the divide-and-round cycle on its own after loading. A semi automatic dough divider rounder costs less and suits moderate daily output; fully automatic is designed for higher throughput operations where operator time is the limiting factor.

Which model handles standard burger bun dough (75–100g)?

The RMG-30S (30–100g range) or RMG-26S (50–140g range) covers standard burger bun weights. Contact us with your exact target weight and we can confirm which model and press setting is most appropriate.

Can one machine handle multiple dough weights?

Each model is optimized for its specified weight range. Operators sometimes run slightly above or below the stated range with minor adjustments, but for consistent results, the specified range is the practical working window. If your menu requires two significantly different piece weights, the mold-swappable tabletop models may be a better fit.

Is 220V or 380V better for this machine?

Both deliver the same performance. The choice depends on your facility’s available power supply. 220V single-phase is the more common choice for smaller operations; 380V three-phase suits larger factory environments where three-phase infrastructure is already in place.

What is the approximate output per hour?

Output depends on the operator’s reload cycle time and batch weight. A realistic estimate for an experienced operator is 15–25 press cycles per hour, giving approximately 150–900 pieces per hour depending on the model’s piece count. Contact us for a more precise estimate based on your production requirements.
