RESTAURANT EQUIPMENT MANUAL DUKE PROOFER OVEN DO NOT… • Run the proofer humidity without a load of dough. It is OK to leave the proofer heat on to maintain the temperature, but turn the humidity off if the proofer is empty. • Let the dough dry out while it is thawing. Dough that is too dry will not fully rise in the proofer and may crack. • Over-proof the dough Excessive proofing will cause the bread to collapse after it has been baked. Make sure to adjust the proofing time to prevent over-proofing.
