Final Proofer

Final Proofer. An enclosure, with controlled atmospheric conditions, in which the formed dough pieces are subjected to a final period of active fermentation (q.v.) to attain the proper volume and conditioning for baking. Depending on its design, the proofer, also called a steam box, may be loaded manually with racks (q.v.) that carry the dough loaves (q.v.), or it may be automated with the dough traveling through it for the required time period on racks, trays (q.v.) or conveyors (q.v.), or it may be of the continuous type (q.v.).
