Key benefits Odor-free fermentation: Runs without unpleasant smells so the natural flavors of your food are preserved and there is no cross-contamination of odors between batches. Precise, repeatable results: Advanced temperature control maintains conditions within 0.1°C, giving consistent fermentation and predictable outcomes. Built-in safety: Thermal protection at 75°C prevents overheating, protecting the device and your ingredients. Reliable thermal performance: High-quality insulation and a dual-sided heating pad reduce heat loss and keep temperatures stable for both warm and cool processes. Features and materials Odor-free operation: Designed to avoid introducing foreign odors during fermentation, preserving product quality. Thermal protection: Automatic cutoff at 75°C to stop overheating and improve safety. Superior insulation: Inner layer constructed from aluminum film and pearl cotton, securely sealed and carefully stitched to prevent bursting and provide effective insulation for hot and cold use. Accurate temperature control: Digital control meter with 0.1°C precision. Factory/typical settings include a start point (PO) at 24.0°C and a stop point (P1) at 33.4°C. Indicator light shows normal heating at 24.0°C and turns off at 33.4°C to signal the end of the heating cycle. Dual-sided heating pad: Front: Black waterproof fabric for dirt resistance and easier cleaning. Back: White insulation cotton to reduce heat loss and help maintain stable temperatures. The electric heating pad is washable; however, keep the interface and electronic components dry at all times. Performance and compatibility Designed for food fermentation applications that require stable temperatures in the device’s control range (noting the PO and P1 settings). The combination of precise control, secure insulation, and a washable heating surface makes the unit suitable for repeated home or small-scale use. Follow the wash and handling guidance to protect the control interface and extend product life. Care and safety notes Do not immerse the control interface or electronic components in water. Keep connectors, controls, and seams dry when washing the heating pad. The built-in 75°C thermal protection is a safety feature but does not replace proper supervision during extended fermentation cycles. Inspect seams and the heating pad regularly for damage; the inner aluminum film and pearl cotton layers are sealed and stitched to resist bursting, but wear and tear may occur over time. Typical use scenarios Sourdough starter maintenance and propagation: Maintain a stable 24–33.4°C environment for consistent microbial activity and predictable starter behavior. Dough proofing: Create a controlled warm environment for proofing bread dough to achieve reliable rise times and texture without introducing off-odors. Room-temperature ferments such as kombucha or lacto-fermented vegetables: Provide gentle, steady warmth in the specified control range to support steady fermentation and flavor development. What makes it stand out Odor-free design plus precise 0.1°C temperature control for consistent, high-quality fermentation outcomes. Durable, well-stitched aluminum film and pearl cotton insulation for effective thermal management and resistance to bursting. Dual-sided washable heating pad with a washable front surface and insulating back layer—designed for practical use while emphasizing safe handling of electronic parts.
