Bakery moulder : how to choose the right one?

The moulder supports the baker through one of the most delicate stages of bread making: turning a round dough piece or a block into a baguette. It is found in almost every mechanised bakery, and the choice of machine directly affects the consistency and quality of the bread.

Choosing the right one is not just a matter of output. It means understanding how the machine works the dough, and matching it to the type of bread you produce.

How does a moulder work?

A moulder shapes the dough pieces after dividing and intermediate proofing. It reproduces the baker's hand movements and can process from several hundred to several thousand pieces per hour, with consistent results.

It works in three stages.

• Sheeting: the dough piece passes between rollers that flatten it into a sheet, while releasing as little gas as possible to preserve the fermentation achieved in the previous stages.
• Curling: the sheet is rolled up on itself. This is a decisive stage that structures the future crumb and gives the bread its chew.
• Elongation: the curled dough piece is stretched to the required length.

Depending on the model, a moulder handles dough pieces from 50 g to 2,000 g, at outputs suited to artisan bakeries as well as the highest volumes.

Vertical or horizontal moulder?

This is often the first question bakers ask, and the answer is fairly simple.

• The vertical moulder is compact and cost-effective. The dough piece drops through the rollers before being elongated, all within a small footprint. The Trégor is the best-known example: it has built MERAND's reputation worldwide for decades and remains the best-selling machine in the range. Reliable, precise and versatile, it is the benchmark moulder for artisan bakeries: with a simple adjustment, it switches from baguettes to sandwich loaves, from bâtards to half-baguettes, and supports bakers from their first setup through to expanding their product range.

Its key feature has a name: PPR (Progressive and Adjustable Pre-Sheeting). This exclusive system automatically adjusts the pre-sheeting roller to the height of each dough piece, ensuring correct pre-sheeting across all weights, from the smallest to the largest, without degassing the dough. The Trégor Tradition version adds two patented systems, Alvéo+ and Pointop (automatic pointed ends), to get the very best out of Tradition doughs.

• The horizontal moulder elongates the dough on a fixed table, along which a moving belt rolls it exactly as the baker's hand does on the workbench. Elongation becomes long and gradual, the dough does not heat up, and the result comes close to hand moulding. This is the principle used on Armor moulders, and it explains their reputation for delicate doughs and Tradition baguettes. In the Armor Tradition version, it is also fitted with Alvéo+ and Pointop, for particularly gentle moulding. Whether vertical or horizontal, the floor footprint remains very compact in both cases: the choice depends on the type of bread and the elongation quality you are looking for, far more than on the space available.

The special case of high-hydration doughs

A dough at 75% hydration behaves very differently from a dough at 60%. It contains more water, which makes its gluten network more extensible but also more delicate to handle. It tends to stick to rollers and belts, does not tolerate being stretched too quickly, and degasses easily under pressure. Yet this gas, produced during bulk fermentation, plays a major part in the open crumb structure and volume of the finished bread. As these doughs have become standard for Tradition bread, the issue now concerns most bakeries, starting with artisans.

At the sheeting stage, better results are achieved with pre-sheeting that accompanies the dough rather than a single pass that forces it. This is the whole point of PPR on the Trégor, and of the Alvéo+ system, whose dimpled surface resembles a golf ball: it reproduces hand sheeting and avoids degassing even the most fragile doughs.

At the elongation stage, the way the dough is stretched matters just as much: on a fixed table, the Armor stretches it gently, in two phases, without tearing or heating it. This is exactly what high-hydration doughs require.

One machine, several breads: the options

Beyond a certain pace, the challenge becomes consistency: getting the same result from the first to the last dough piece of the day. A machine running for several hours in a row builds up flour, warms up slightly, and the dough it receives at the end of the session no longer has quite the same temperature or strength as at the start.

In this context, a moulder's capacity is not just the number of dough pieces it can process per hour. The machine's design, its robustness and the stability of its settings matter just as much. The aim is to maintain consistent moulding quality, without increasing interventions or slowing down production.

For bakeries that handle large volumes every day, it therefore makes sense to think in terms of the whole day rather than a single batch. A suitable moulder must keep pace with production without moulding quality varying over the hours.

And when volumes increase?

As production grows, the challenge becomes consistency: getting the same result from the first to the last dough piece of the day. A machine running for several hours in a row builds up flour, warms up slightly, and the dough at the end of the session no longer has quite the same temperature or strength as at the start. Design, robustness and stable settings then become as important as output.

The MERAND range supports this growth without changing its philosophy. The Armor I adds five sheeting rollers and a motorised flour duster, and sustains up to 2,000 pieces/h over long sessions. The Armor HV (High Volume) is a reinforced version of the Armor Tradition, with its Tradition Pack that limits degassing at sustained outputs. Finally, at the top of the range, the Proform and its C2A (Assisted Elongation Control) system reach 2,500 pieces/h for high-throughput automatic lines. The same respect for the dough, on an industrial scale.

For bakeries that handle large volumes every day, it therefore makes sense to think in terms of the whole day rather than a single batch. A suitable moulder must keep pace with production without moulding quality varying over the hours.

And when volumes increase?

First, the weight of your dough pieces, since not all machines cover the same range. Next, output, to be measured against your largest batch and the time available. Then the type of dough you work with, as this determines the requirements for sheeting and elongation. And finally, consistency with the rest of your line, since the moulder works hand in hand with the dividing and intermediate proofing stages that precede it.

Moulding is, moreover, only one stage among others. Dough that has been well mixed, well divided and well rested arrives at this stage in better condition: it is the consistency of the whole line that makes the quality of the bread.
