Bühler OptiBake wafer baking oven

The Bühler Group OptiBake wafer baking oven is powered by electric induction heating technology, which is claimed to be able to reduce energy consumption by 50% compared to conventional gas-fired wafer baking ovens.

Suitable for industrial baking applications, the induction heating system uses electromagnetic fields to generate heat directly within the baking plates. The result is a process that does not produce any direct emissions of carbon dioxide (CO₂), carbon monoxide (CO) or nitrogen oxides (NO_x). The environmental benefits of the oven are even greater when powered by a low-carbon electricity mix.

At the heart of the oven’s performance is a newly engineered baking plate design, specifically developed to produce the high-quality wafer sheets. Paired with a system for individual plate temperature control, it is designed to provide precise and consistent heat distribution throughout the baking process. With the ability to fine-tune temperatures plate by plate, the oven should not only improve product quality but also allow for flexibility and responsiveness — which is key for handling recipe changes or varying production demands.

The low baking chamber temperatures are designed to reduce life cycle costs by minimising thermal stress on components such as cables and bearings. OptiBake also creates a quieter production environment by eliminating burner nozzle flow noise and simplifies heat recuperation due to the absence of combustion products. Furthermore, the oven allows for 100% raw material utilisation, as baking scraps do not burn and can be repurposed. 

The product is designed for safe operation and there is no fire hazard, as there are no open flames in the baking chamber. It is also designed to operate without posing any electromagnetic compatibility (EMV) risks, for safe and interference-free integration into industrial environments.
