WEAVVIOR Folding Bread Proofing Box, 130°F Bread Proofer with 24H Timer | Sourdough starter warmer, dual viewing windows, 3-sided heating & metal rack included, ideal for bread proofing and yogurt

【Foldable & Dual-Window Design】This folding bread proofing box measures 16 × 12 × 12 inches when open and folds down to only 1.8 inches thick, making it easy to store in a cabinet, pantry, or other narrow space. Unlike typical single-window designs, it features a clear top window and a sealed circular front window for monitoring fermentation from two angles without opening the box and releasing heat.
【Precise Proofing Control】This bread proofing box offers adjustable temperature control up to 130°F in precise 1°F increments, plus a 24-hour timer with automatic shutoff. A built-in NTC sensor monitors the internal temperature to support stable, consistent dough fermentation during cold winter months.
【3-Sided Even Heating】 This dough proofer features heating elements built into the left and right walls and the bottom to distribute steady warmth throughout the chamber. The three-sided heating design helps reduce uneven hot and cold areas, supporting more consistent dough rising and fermentation.
【5-Layer Insulated Design】5-layer insulation helps reduce heat loss and maintain stable warmth inside the sourdough proofing box. Independent overheat protection provides added protection during use, while the included metal rack supports bowls, jars, and other fermentation containers above the heated bottom surface.
【Versatile Fermentation Uses】Designed as a sourdough starter warmer and proofing box for sourdough bread baking, it also provides a controlled warm environment for bread dough, yogurt, kombucha, and other fermentation projects. Every unit is backed by a one-year warranty with replacement or refund support.
