Perfect Chocolate Through Precise Temperature Control

For the launch of a new chocolate stroopwafel, Daelmans Stroopwafels from Nieuwkuijk was looking for a reliable way to ensure that the chocolate stroopwafels hardened under controlled conditions. Fat bloom—the white discoloration that occurs in chocolate—must be prevented. Since the process was new, Daelmans deliberately chose to rent the equipment: to gain experience first, fine-tune the process, and ensure quality. Coolworld developed two custom-built tempering chambers that allowed the temperature to be precisely raised and maintained at a stable level for 48 hours.

How did Coolworld help Daelmans?

  • Mastering a new production process for chocolate stroopwafels, in which temperature is crucial to prevent fat bloom.
  • The stroopwafel is heated in a controlled manner from +18 °C to +27 °C and then kept at exactly that temperature for 48 hours. Finally, the stroopwafels are cooled back down to +18 °C.
  • Two custom-built tempering chambers made it possible to deliver consistent quality and provide full transparency into the process.

Continuous Process

The introduction of a new product requires certainty, flexibility, and complete process control.
For Daelmans, this meant a smart solution for perfectly tempering their chocolate stroopwafels without compromising on quality.


By opting for a rental solution, they were able to get started quickly while simultaneously optimizing their process.
With custom-built tempering cells and precise temperature control, the risk of fat bloom was effectively prevented.
In addition, real-time monitoring provided continuous insight and added assurance at every stage of production.
The result: a stable, reproducible process and consistent product quality.
