1. Odor operation: This household fermentation machine operates without any peculiar smells, ensuring that the taste of your food remains unaffected during the fermentation process. It features builtin thermal protection at 75°C to prevent overheating and enhance safety. 2. thermal insulation: Constructed with a combination of aluminum film and pearl cotton, the inner layer is tightly sealed and expertly stitched to prevent bursting. This meticulous workmanship ensures longlasting thermal insulation for both hot and cold use. 3. Accurate temperature management: Our fermentation machine includes a precise temperature control meter that regulates temperature within 0.1°C. Set the starting temperature (PO) at 24°C and the stopping temperature (P1) at 33.4°C. The indicator light signifies normal heating when at 24°C, turning off once 33.4°C is reached, indicating the end of the heating cycle. 4. Dualsided heating pad design: The front is made of black waterproof fabric for enhanced dirt resistance, while the back is equipped with white insulation cotton to minimize heat loss. The electric heating pad is washable, but care should be taken to keep the interface and other components dry.
