Puffing Application Center, Uzwil

Application Center

The Bühler Puffing Application Center is an innovation hub designed to support food and feed manufacturers to test, develop, optimize, and innovate puffed products made from a wide variety of grains and pulses, such as quinoa, chickpeas, and ancient grains.

Puffing is a hydrothermal process that uses heat and pressure to significantly expand the volume of raw materials. The technology is versatile and applicable to a broad range of intermidiate and final products such as snacks, ready-to-eat breakfast cereals, confectionery, bakery items, and dairy applications.

The Puffing Application Center is fully integrated into Bühler’s research and training network in Uzwil, which includes facilities such as the Grain Innovation Center, Flavor Creation Center, Food Creation Center, and Protein Application Center. This unique configuration enables customers to develop complete product concepts – from puffed snack pellets to cereal bars and chocolate applications – all within a unified innovation process.
