Precise temperature control: This fermentation machine delivers accurate temperature regulation to within 0.1 C. The programmable start temperature (PO) is 24 C and the stop temperature (P1) is 33.4 C. The control panel displays the current temperature, and a heating indicator shows when the unit is actively heating. When the temperature reaches 33.4 C, the heating indicator turns off. Odor operation: Fermentation proceeds without any unpleasant odors affecting your food. This household fermentation machine operates odor during use and includes builtin thermal protection at 75 C to prevent overheating of the heating pad, enhancing safety. Consistent temperature distribution: The bottom heating pad provides uniform heat across the entire surface, ensuring every item receives even warmth throughout the fermentation cycle. The 75 C thermal protection switch adds an additional layer of safety. quality insulation: Built with a combination of aluminum film and pearl cotton, this fermentation box is easy to clean and maintain. Tight seams prevent leaks and contribute to reliable insulation for both hot and cold items. The box is foldable for convenient storage when not in use. Design and practicality: Compact and foldable for easy storage, with a focus on reliable performance and longevity. Suitable for home fermentation applications that require precise control, safety, and odor operation. Use scenarios: Dairy fermentation: Maintain steady warmth for yogurt or other dairy ferments that require precise temperature ranges. Vegetable ferments: Create consistent conditions for kimchi, sauerkraut, or pickles to optimize texture and flavor. Beverage and starter preparation: Support steps for kefir, kombucha, or sourdough starter that benefit from stable temperatures over extended periods.
