- Odor-free operation: This household fermentation machine runs without peculiar smells, keeping the taste of your food intact during fermentation. It includes built-in thermal protection at 75C to prevent overheating and improve safety. - Superior thermal insulation: The inner layer combines aluminum film and pearl cotton, tightly sealed and expertly stitched to prevent bursting. This construction provides durable insulation for both hot and cold use and helps maintain stable temperatures. - Accurate temperature management: A precise temperature control meter regulates temperature within 0.1C. Set the starting temperature (PO) at 24C and the stopping temperature (P1) at 33.4C. The indicator light shows normal heating at 24C and turns off when 33.4C is reached, signaling the end of the heating cycle. - Dual-sided heating pad design: The front is black waterproof fabric for dirt resistance, while the back uses white insulation cotton to minimize heat loss. The heating pad is washable, but keep the interface and other components dry. - Applications: suitable for home fermentation of yogurt, kefir, kimchi, sauerkraut, and other foods requiring controlled warmth; supports dough proofing or starter cultures; provides odor-free operation with precise temperature control for sensitive ferments.
