Delicate Strudel Dough Picked and Packed in Enclosure-Free Robot Cell

At Weinbergmaier GmbH in Vienna, Sissi and Franz—as their human operators have quaintly named the two Stäubli robots—pack high-quality strudel dough in perfect synchronization within a cycle time of 1.5 sec.

For even the most gifted amateur baker, pulling strudel dough is a challenge. The delicate dough must be thoroughly kneaded and stretched out as thin as possible, preferably so thin that light shines through. Anyone who masters the intricacies of this process earns the reward of tasting the filling in all its glory, because strudel has a far lower dough content than even a puff pastry.

The earliest known strudel recipe dates back to 1696 and originated in Vienna, Austria. Here, in the “pastry capital of the world,” the 22nd district, to be precise, a company has been manufacturing strudel dough on an industrial scale for the past half century. Weinbergmaier GmbH, acquired by the Vivatis/Raiffeisen Group in 2018, produces the Toni Kaiser brand of strudel dough on three production lines to the highest standards and in large volumes.

Shares Factory Manager Peter Baumüller, “We could completely fill a football field with a single-day’s production of our Viennese strudel dough, and our annual production, laid out in a row, would stretch 800 kilometers.” That’s the equivalent to the distance from Vienna to Frankfort, or almost to Florence.

Because the wafer-thin product must not be allowed to tear, the mechanical pulling of the dough places very high demands on the machinery involved. The highly specialized production lines have been in operation for around 50 years and are serviced with great dedication by the maintenance team. “These production lines deliver strudel dough of the best confectionery quality,” says Baumüller. “There is no way we could obtain machines of such a solid design today. That’s why we look after them like they’re ‘the apple of our eye.’”
