Advantages of the hybrid baking technique
Hybrid baking plus vacuum cooling is real vacuum baking
Faster baking:

Greater flexibility and better baking results.

Very suitable for white baking with the interrupted baking method of VaC Technology: 

With hybrid baking technology,  outside and inside can be baked at the same speed, similar to cooling with a vacuum. This allows baked goods to be finished on the inside even though they are still white on the outside.

These baked goods can then be finished very quickly in the in-store oven, as heat only needs to be applied to the outside for browning; this is possible at a high temperature and correspondingly short baking time.

Interaction of hybrid oven and vacuum cooling

A very good match in terms of baking technology, as both systems shorten the baking time, increase flexibility and support white baking.

The design and handling with the look and feel of the hybrid oven and vacuum chamber fit together very well and support the optimum overall package (cabinets with sliding doors). Both systems are optimally prepared for automation thanks to the automatic doors. Obvious, simple expansion with proofing cabinets is possible, as these  have a similar structure.

These baked goods can then be baked very quickly in the in-store oven, as heat only needs to be added to the outside for browning; this is possible at a high temperature and correspondingly short baking time.

The expert opinion:

“Eddy Sprenger was able to find a solution to the problem with the pumps years ago. However, he did not just look for a solution to this detail but considered vacuum cooling technology as a holistic innovation. With his third-generation systems, which technologically enable the optimal cooling of a wider range of bakery products, the economically absolutely necessary use of vacuum technology in the bakery industry will be successful.

Thanks to the years of experience concentrated in the VaC-Technologie team and Eddy Sprenger, it will be possible to bring this real and absolutely necessary innovation to bakeries in order to lead this industry to new successes in difficult economic times.”
