Combine the proofing and baking process into one machine with the NU-VU QB-3/9 double deck electric oven proofer combo! Start by proofing your products in a cavity that features separate easy-to-use timers for optimum control over the rising process. Once proofing is finished, easily move the pans to the oven, where the patented V-Air fan system distributes controlled, heated air evenly to help you bake faster and more consistently! This stacked unit will hold 9 full size (18" x 26") sheet pans in the proofer and 3 sheet pans in the oven, which reaches a temperature up to 425 degrees Fahrenheit.
