This strategic move positions Bühler as a comprehensive solution provider amid growing global demand for healthy, traceable snacks.

Swiss technology company Bühler Group has integrated NapaRoast’s pasteurization and roasting technology. With the addition of the NapaRoast steam vacuum pasteurization technology to its broad portfolio, Bühler strengthens its market position in the nuts processing industry to cater even better to trends such as healthy snacking, regulatory compliance, and sustainable practices. “The integration of NapaRoast puts us in the unique position to be a one-stop shop for our customers. The best-in-class pasteurization process guarantees food safety and traceability, and, in combination with our proven technologies for nuts processing, added efficiency. With the integration of the NapaRoast solution into our portfolio, we look forward to sharing the benefits of this technology and serving the NapaRoast customer base – not just for nuts, but for many of the food processing solutions Bühler offers as well,” says Cathrin Flühler, Head of Market Segment Nuts at Bühler.

The global nut market is growing at an annual rate of up to 7%. The popularity and reputation of tree nuts and ground nuts as healthy snacks due to their high levels of protein, fiber, and antioxidants is growing steadily. With this developing worldwide demand comes an increased focus on food safety. NapaRoast’s steam-vacuum pasteurization process provides the best answer to the stringent microbial contamination requirements that processors are facing today. “Our pasteurization process offers a high pathogen reduction of >5 log in nuts, seeds, and all low moisture foods. During our process steam is used to raise the surface temperature of the product to kill pathogens effectively,” explains Dr. Cameon Ivarsson, Co-Founder of NapaRoast. By pasteurizing with saturated steam, the products can be treated effectively at lower temperatures in a partial vacuum. The high efficiency of saturated steam does not require a drying step thus protecting the quality, texture, color, and flavor of the product.

The missing piece to the puzzle

“We already covered the most important steps such as transport, sorting, storage, roasting, and grinding in our portfolio. When it came to the pasteurization process, however, we had to rely on solutions from suppliers. Now, our customers can get all the important technologies along the value chain from Bühler, which creates valuable synergies for everyone involved. This collaboration is a perfect match between two companies with the same values such as quality, ingenuity, and creating value for customers and consumers,” says Cathrin Flühler.

Cameon Ivarsson adds: “With Bühler, there is a huge opportunity to multiply the impact of our pasteurization technologies across the globe. Their large customer base paired with decades of experience in plant and process engineering will get the most out of the technology. We could not be more excited about the future for nuts processing.”

The NapaRoast pasteurization technology is installed in over 40 processing plants around the world, mainly in the United States, Europe, and Africa. Pasteurization and roasting lines are offered in throughputs ranging from 1 tonne per hour to 6 tonnes per hour. Because of the unique design of the process where the product is treated in bulk bins, there is no breakage, dust, and waste, and down time for product changeover is minimized. Its flexibility allows for the processing of whole pieces, chopped ingredients or powders as well.

A unique playground for nuts processors

To showcase its position in nuts processing and to give customers the unique opportunity to test and train along the value chain, Bühler has upgraded its Flavor Creation Research and Training Center in Uzwil, Switzerland. “Of course, the pasteurization step is integrated into our state-of-the-art facility for our customers to get first-hand experience of the technology. We are excited to open our center in August this year for trials and to invite them to the first exclusive training session on November 4 and 5,” says Cathrin Flühler.

Bühler Group’s new OptiBake oven revolutionizes industrial baking with inductive heating technology that delivers precise temperature control, superior wafer quality, and up to 50% energy savings. As the first of its kind, it sets a new sustainability standard by eliminating direct emissions and reducing operational costs—marking a major leap toward zero-emission wafer production.

“With OptiBake, we set out to deliver more than just a new wafer oven. We challenged ourselves to combine exceptional wafer quality with unprecedented flexibility, while enabling customers to contribute to sustainability,” says Sandra Lutz, Head of Business Unit Wafer at Bühler Group. “Our electric induction heating technology responds to the global demand for higher quality and efficiency, reduced operational costs, and a significantly lower carbon footprint.”

For more than a decade, Bühler’s has focused on developing technologies that support customer growth while reducing the environmental footprint of production. OptiBake offers a range of unique advantages that set it apart from conventional gas-fired or electric wafer ovens. While conventional electric heating has been used for decades, inductive heating offers greater energy efficiency and new possibilities for precise control.

OptiBake’s induction heating system uses electromagnetic fields to generate heat directly within the baking plates, dispensing with open flames and combustion. The result is a process that produces no direct emissions of carbon dioxide (CO2), carbon monoxide (CO), or nitrogen oxides (NOx). Energy consumption can fall to 50%, when compared to gas-fired or electrical wafer ovens, reducing the environmental impact. These emission reductions can also lead to tax and licensing advantages, along with increased subsidy opportunities.

The environmental benefits of the oven are even greater when powered by a low-carbon electricity mix. In such settings, it can significantly reduce CO₂ emissions and support broader sustainability goals. By eliminating reliance on natural gas, the system also contributes to energy security and supply resilience.

Enhanced quality and efficiency

At the heart of the oven’s performance is a newly engineered baking plate design, specifically developed to produce the highest wafer sheet quality in combination with the inductive heating system. Paired with an innovative system for individual plate temperature control, it ensures precise and consistent heat distribution throughout the baking process. The ability to fine-tune temperatures plate by plate not only improves product quality but also allows for exceptional flexibility and responsiveness – key for handling recipe changes or varying production demands. In fact, induction heating provides the ideal foundation for precise process control, enabling the system to respond quickly and efficiently to varying production requirements, ensuring consistent product quality and optimized energy use.

The low baking chamber temperatures reduce life-cycle costs by minimizing 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 new oven allows for 100% raw material utilization, as baking scraps do not burn and can be repurposed. Its operation is safe with no fire hazard as there are no open flames in the baking chamber. The system is also designed to operate without posing any electromagnetic compatibility (EMV) risks, ensuring safe and interference-free integration into industrial environments.

“With rising CO2 taxes, volatile energy prices, and changing consumer demands, companies must act now to stay ahead,” says 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.”
