Exceptional Thermal Insulation The inner layer blends aluminum film with durable pearl cotton and uses tight stitching to prevent bursting. This design maintains stable temperatures and minimizes heat loss for both hot and cold applications, helping your fermentation process stay consistent and energyefficient. Odor Operation and Safe Heating Designed for safety and quality, this household fermentation machine operates without unpleasant smells that could affect flavors. It includes a builtin 75°C thermal protection feature to prevent overheating of the heating pad, enhancing overall safety and reliability. Accurate Temperature Control The device delivers precise temperature regulation with an accuracy of 0.1°C. You can set the start temperature (P0) to 24°C and the stop temperature (P1) to 33.4°C. The temperature control meter shows 24°C while heating is active, and when the target of 33.4°C is reached, the indicator light turns off, signaling the end of the heating phase. This precision supports repeatable fermentation results and consistent product quality. Innovative DoubleSided Heating Pad The pad features a black waterproof fabric on the front for easy cleaning and a white insulation cotton layer on the back to minimize heat loss. The heating pad itself is washable, but care should be taken to keep the interface and other components dry during cleaning. Practical Applications Yogurt and dairy fermentation: maintain a stable warm environment within the 24–33.4°C range to optimize cultures and texture. Vegetable or bean fermentation: provide a consistently warm setting for kombucha, miso, tempeh, or other starterbased ferments. Starter culture preparation and activity: create reliable warmth for activating or sustaining microbial cultures prior to processing or packaging.
