Proofing Requires a Humid and Controlled Environment
During proofing (fermentation), dough needs to be kept within a specific temperature and humidity range. If the environment is too dry, the dough surface forms a crust and rising is affected; if conditions change each time, the results will also differ from batch to batch. A steam/proofing chamber makes these conditions fully controllable.
What Does a Steam Room Provide?
By keeping humidity and temperature under control, a steam room makes the resting and proofing stages of dough more consistent and repeatable. This prevents the dough surface from drying out, supports balanced fermentation, and ensures that the dough entering the oven has passed through similar conditions each time.
Custom Manufacturing for Your Needs
Stilsan also provides solutions for independent steam rooms and proofing chambers; the system is sized according to your operation’s capacity and process. We have also completed fully automatic fermentation chamber installations. If you share your requirements, we can determine the right solution together.
Frequently asked questions
- What is a proofing chamber used for?
- A proofing (fermentation) chamber keeps dough at controlled temperature and humidity, making fermentation consistent and repeatable. The dough surface does not dry out, rising remains balanced, and each batch passes through similar conditions.
- Are a steam room and a proofing chamber the same thing?
- Both are based on providing controlled humidity and temperature. A proofing chamber focuses specifically on the fermentation stage, while a steam room is a general solution for processes where dough needs to be rested and humidified.
- Are steam rooms custom-manufactured for installation?
- Yes. The chamber and steam system are custom-manufactured and sized according to your operation’s capacity and process. Stilsan has also completed fully automatic fermentation chamber installations.
