Controlling humidity reduces baking time, prevents drying and cracking and improves the quality, color and surface texture of baked goods. To give customers these results, we offer a steam injection system that controls moisture levels in the bake chamber as an option in all BABBCO custom tunnel ovens.

The BABBCO steam injection unit injects steam into the supply ducts of the oven temperature zone while controlling steam flow with a PLC controlled modulating valve. Vaisala high-temperature humidity sensors and a variable-speed exhaust system are used to control the humidity levels in each oven zone. The PLC control system can be programmed with recipes that default to pre-determined settings.

Pioneering Steam Injection and Humidity Control

BABBCO pioneered the use of steam injection and humidity control in baking. The American Institute of Baking confirms that controlled humidity reduces baking time, prevents drying and cracking and achieves consistent quality, color and surface texture.
