Electric proofer, also known as a proofing cabinet or proofing oven, is a kitchen appliance used in commercial bakeries and pastry shops to help dough rise before baking. The proofer provides a warm, humid environment that allows the yeast in the dough to ferment and produce carbon dioxide gas, which causes the dough to expand and rise. The proofer typically consists of a cabinet with a heating element and a water reservoir that generates steam to maintain a high level of humidity. The temperature and humidity levels can be adjusted to suit the type of dough being proofed, and the proofer may have multiple shelves to accommodate large batches of dough. The use of an electric proofer can help to speed up the bread-making process and produce consistent results.
