Precise Temperature Control The fermentation box uses a DC power supply to deliver stable, reliable heating. Precise temperature control helps dough fermentation achieve a perfect rise and supports consistent results for items such as sweet wine, rice milk, and yogurt. Thermal Insulation The inner layer combines high quality aluminum film and pearl cotton to provide excellent insulation, helping maintain the ideal fermentation temperature for home bakers. Odorless Heating Pad The heating pad is odorless, so it will not affect the taste of your fermented products. It keeps food and drinks warm at the desired temperature for an extended period. Foldable and Portable Design The box folds for easy storage and portability. A handle facilitates transport, and the zipper closure minimizes heat loss during fermentation. Use scenarios - Ferment bread dough at a controlled temperature to achieve a reliable, uniform rise. - Produce yogurt with stable warmth to ensure consistent fermentation results. - Ferment rice milk or sweet wine, maintaining steady heat for improved flavor development.
