Benchmark Quality Speculoos with 50% Lower Energy Using a Data-Driven Hybrid Steel Belt Oven

Hybrid Steel Belt Oven

Client

Vermeiren

Country

Belgium

Vermeiren is a legacy Belgian biscuit brand, internationally recognized for its artisanal speculoos, a crisp, caramelized biscuit delicately spiced and golden baked. With a strong presence in Europe and beyond, Vermeiren maintains rigid product standards across all baking lines, especially in terms of texture, flavor, color, and consistency.

The Challenge

Vermeiren needed to install a new baking oven on their expanded production line, but with a clear condition

Vermeiren needed to install a new baking oven on their expanded production line, but with a clear condition: “The new oven must replicate the exact baking performance of our traditional ovens. We cannot compromise the speculoos product quality under any circumstances.” Their key objectives are

  • Preserve the unique bake profile of speculoos
  • Achieve perfect consistency in caramelization and color
  • Lower energy consumption
  • Avoid long tuning periods during startup
  • Maintain the signature surface and bite achieved using steel belt baking
Our Engineering Approach

Data Before Design

Rather than rely on assumptions, New Era deployed a specialized Data Logger inside Vermeiren’s existing ovens to scientifically capture the baking conditions responsible for the perfect speculoos outcome.

We Recorded and analyzed

Zone-wise temperatures

Zone-wise temperatures

Heat flux and distribution patterns

Heat flux and distribution patterns

Moisture release rate and drying curve

Product core temperature and timing

Airflow, exhaust, and humidity control

Airflow, exhaust, and humidity control

This allowed us to map the exact thermal fingerprint of there speculoos production process.

The Solution

A Custom Hybrid Steel Belt Oven

Zonal control of top and
bottom heat

Hybrid heating flexibility:
enabled radiation & convection

Intelligent PLC system for precise,
repeatable control

Balanced airflow and exhaust
system for moisture control

Product-specific oven length
and bake zone configuration

Hygienic design for easy cleaning
and low downtime

Commissioning

First Results After Fine-Tuning

Once the oven was installed and fine-tuned to match the data profile

  • The first production batches delivered benchmark quality speculoos
  • Color, texture, and flavor matched and exceeded the output of legacy ovens
  • No additional rework or hardware changes were needed post commissioning

The client declared:

“This is the highest quality speculoos we have ever produced.”

Energy Savings

A Massive Operational Gain

Beyond quality, the new oven delivered impressive energy efficiency:

50% lower gas

consumption compared to
traditional ovens

Reduced carbon footprint

and energy cost per kg
of biscuit

Stable baking

with minimal manual
adjustment
