- Exceptional Thermal Insulation: The inner layer combines aluminum film with durable pearl cotton and reinforced stitching to prevent tearing. This design provides durable, long lasting insulation for both hot and cold fermentation, helping maintain stable temperatures with efficiency. - Odor-Free Operation and Safety: Designed for safe, high quality use in home fermentation. There is no unpleasant smell affecting food taste, and a built in 75°C thermal protection helps prevent overheating of the heating pad for safer operation. - Accurate Temperature Control: Delivers precise temperature regulation within 0.1°C. Set start temperature P0 at 24°C and stop temperature P1 at 33.4°C. The control meter shows 24°C during heating, and when 33.4°C is reached the indicator light turns off, signaling the end of the heating phase. - Innovative Double-Sided Heating Pad: Features a black waterproof front for easy cleaning and a white insulation cotton back to minimize heat loss. The heating pad is washable, but the interface and other components should be kept dry during cleaning. - Practical Use Scenarios: - Fermenting dairy products such as yogurt or kefir at a stable around 32°C to support culture activity. - Maintaining a steady warm environment for sourdough starter or other low acid ferments. - Fermenting vegetables (eg, kimchi, pickles) or beverages that require a controlled warm range between 24°C and 33.4°C for reliable results.
