Roll-In Retarder Proofer — Trolley-In, Dual Temperature, 32 to 128 Trays

R&M’s roll-in retarder proofer series handles high-volume bakery production where individual tray loading is impractical. A complete trolley of shaped dough rolls directly into the cabinet — then cools to retardation temperature, holds, and automatically rises to proofing temperature on a programmed schedule. Three models: GD-32DS (32 trays, refrigerate+freeze), GD-128DS (128 trays, refrigerate+freeze), and GD-15FP (16 trays, spray proofing only). 220V.

Why Roll-In Format Changes the High-Volume Production Equation

In a standard reach-in proofer — whether a boiled water, spray, or retarder model — trays are loaded individually onto internal racks. For a 32-tray cabinet, this means loading and unloading 32 separate trays per cycle. Each tray handling step risks disturbing shaped dough and adds operator time at a stage where the production line is moving fast.

A roll-in proofer eliminates this step. The trolley — a freestanding rack on wheels pre-loaded with up to 32 or 128 trays of shaped dough — rolls through the cabinet door in one move. The door closes. The cabinet manages temperature. When the program cycle completes, the trolley rolls out and goes directly to the oven.

The productivity math: A 32-tray roll-in proofer loaded in one trolley push takes approximately the same operator time as loading 3–4 individual trays into a reach-in unit. For an operation running 3–5 proofing cycles per shift, the time saved per cycle compounds across the working day.

The dough quality argument: Shaped dough — croissants, buns, rolls — is fragile. Each time a tray is physically moved from rack to rack, there is a risk of deforming shaped pieces. Roll-in loading, where the dough never leaves the trolley until it moves to the oven, minimizes this handling risk.

GD-32DS — The Practical High-Volume Entry Point

The GD-32DS holds one trolley with 32 trays (400×600mm each). At 1,150×810mm floor footprint and 197kg, it is the most compact model in this roll-in series while still delivering full dual-temperature retardation and proofing capability.

Dual temperature configuration: The cabinet operates in two temperature zones — refrigeration (2–5°C for cold retardation) and freeze (0 to −15°C for deep cold holding). The trolley loaded with shaped dough first cools to the retardation temperature to slow fermentation, then automatically rises to proofing temperature at the programmed time. When the proofing cycle completes, the trolley rolls out ready for the oven.

Who this suits: A hotel central kitchen producing fresh rolls and croissants daily, a chain bakery running overnight production for morning-supply outlets, or any bakery where 32 trays per cycle at a controlled overnight schedule represents the production target.

GD-128DS — Industrial-Scale Overnight Production

At 1,920×2,030mm footprint and 9.9KW, the GD-128DS holds two trolleys with a combined 128 trays. This is the industrial-scale version of the same concept.

Who this suits: Wholesale bakeries supplying supermarkets or institutional customers, industrial bread plants running overnight production cycles, and food manufacturing operations where a single proofer-retarder cycle needs to cover the full next-day supply in one programmed run.

128 trays at 400×600mm each, produced in one overnight cycle with no staff required to manage the temperature transition — this is the production efficiency case for large-scale overnight retardation.

GD-15FP — Roll-In Spray Proofer (Without Retardation)

The GD-15FP is a roll-in format spray proofer without refrigeration — it provides proofing conditions only (room temperature to 50°C), not retardation. One trolley, 16 trays, 600×1,020mm footprint, 1.8KW.

Who this suits: A high-output bakery that manages retardation in a separate cold room or refrigerator and wants the roll-in format for the convenience of trolley-based loading and unloading during the proofing phase. The spray humidity system provides the same high-quality proofing environment as the PXF and RMF series, in a more compact roll-in cabinet.

400×600mm Tray Standard — Cross-Compatibility

All three models are designed around standard 400×600mm trays — the universal standard for European-origin commercial bakery equipment. If you are already using standard bakery trolleys and trays, they are likely compatible with this cabinet.

Confirm tray dimensions with us before ordering if you have existing trolleys from other manufacturers. Non-standard tray dimensions may require custom trolley configurations.

Production Line Integration

The roll-in retarder proofer sits at the junction of shaping and baking in a high-volume bread production line:

1. Dough mixing and dividing: Bulk dough is mixed and divided upstream.

2. Shaping: Dough is shaped — croissants, rolls, buns — and loaded onto trays on the trolley.

3. Roll into retarder proofer: The loaded trolley rolls into the GD-DS cabinet. Temperature program starts.

4. Overnight retardation and automatic proofing: The cabinet cools to 3°C for retardation, then rises to 28°C for proofing at the programmed time.

5. Roll out to oven: When the proofing cycle completes, the trolley rolls directly to the oven line. No tray handling.

This sequence replaces the need for staff to be present during the overnight retardation-to-proofing transition. The machine manages it automatically.

الأسئلة المتكررة

What is the difference between GD-32DS and GD-128DS?

Tray capacity: 32 vs. 128 (two trolleys). The GD-32DS is a single-trolley unit for high-volume commercial bakeries; the GD-128DS is a two-trolley industrial unit for wholesale bakeries and industrial bread plants. Both operate on the same dual-temperature (refrigerate+freeze) programmed cycle.

What trolleys are compatible with the GD-DS series?

The cabinets accommodate standard commercial bakery trolleys for 400×600mm trays. Contact us to confirm compatibility with your existing trolley equipment before ordering.

How does a roll-in retarder proofer differ from a standard retarder proofer?

A standard retarder proofer has internal fixed racks — you load trays individually. A roll-in model has no internal racks — the trolley with trays pre-loaded rolls into the cabinet. The retardation and proofing function is the same; the key difference is how trays are managed. Roll-in is faster and minimizes dough handling risk for high-volume operations.

What is the power requirement for the GD-128DS?

9.9KW at 220V. Confirm that your facility’s electrical supply can handle this draw before installation — a dedicated circuit is typically required for a load of this size.

Is the GD-15FP a retarder proofer?

No. The GD-15FP is a roll-in spray proofer only — it does not refrigerate or freeze. It provides proofing conditions (room temperature to 50°C) in a roll-in format. For retardation capability in roll-in format, the GD-32DS or GD-128DS is the appropriate choice.

How does this compare with a walk-in proofer room?

Both formats handle trolley-based loading at scale. A roll-in cabinet is a self-contained unit for one or two trolleys; a walk-in proofer room is a custom-built space for many trolleys. For 32–128 trays per cycle, the GD-DS roll-in series is the turnkey option. For larger volumes, the walk-in proofer room scales beyond cabinet capacity.
