HVS High Volume Steam
Revent’s patented HVS steel ball steam system was designed upon the fact that the sphere has the greatest surface area to volume ratio of any geometrical form.
The large surface area guarantees maximum steam generation during the baking process. This allows the dough to increase to a large volume in the beginning of the bake and creates a shiny crust at the end of the bake.
The spherical surface of the ball is also perfectly designed to absorb heat, so the steam generator does also serve as a heat accumulator. This heat (energy) is used to shorten the recovery time in the beginning of the bake and between the bakes.
Test results speak for themselves. For example the Revent 724 transforms 8.5 l of water into steam in 20 seconds. Temperature recovery is within 3 – 5 minutes depending on the product and oven model.
