Odor-free operation: This household fermentation machine operates without any peculiar smells, ensuring the taste of your food remains unaffected during the fermentation process. It features built-in thermal protection at 75C to prevent overheating and enhance safety. Superior 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 provides long-lasting thermal insulation for both hot and cold use. Accurate temperature management: Our fermentation machine includes a precise temperature control meter that regulates temperature within 0.1C. Set the starting temperature (PO) at 24C and the stopping temperature (P1) at 33.4C. The indicator light signifies normal heating at 24C and turns off when 33.4C is reached, indicating the end of the heating cycle. Dual-sided 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. Use scenarios: - Yogurt and dairy fermentation: maintain a stable warm environment to culture probiotic dairy products with consistent results. - Vegetable ferments: support sauerkraut, kimchi, and other vegetables that benefit from controlled warmth during fermentation. - Probiotic beverages and starter cultures: create and maintain the ideal temperature for kefir, miso, or kombucha starters.
