LEOBENDORF, AUSTRIA — Bühler Group has introduced OptiBake, an inductively heated wafer oven that reduces energy consumption 50% compared to conventional gas-fired wafer baking ovens, according to the company. OptiBake is tailored for flat and hollow wafers.
“Our electric induction heating technology responds to the global demand for higher quality and efficiency, reduced operational costs and a significantly lower carbon footprint,” said Sandra Lutz, head of business unit wafer at Bühler Group.
OptiBake’s induction heating system uses electromagnetic fields to generate heat directly within the baking plates, dispensing with open flames and combustion. The process produces no direct emissions of carbon dioxide, carbon monoxide or nitrogen oxides. The baking plate design, when paired with a system for individual plate temperature control, ensures precise and consistent distribution throughout the baking process, according to Bühler.
The low baking chamber temperatures reduce life-cycle costs by minimizing thermal stress on components such as cables and bearings. The new oven allows for 100% raw material use, as baking scraps do not burn and may be repurposed.
OptiBake was awarded the Lower Austrian Innovation Award 2025.
“With rising CO₂ taxes, volatile energy prices, and changing consumer demands, companies must act now to stay ahead,” said Johannes Greil, head of product management wafer at Bühler. “OptiBake represents a milestone in industrial baking technology, delivering increased quality, efficiency and flexibility. This powerful combination equips customers to thrive today and remain competitive in the years to come.”
