Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What is the typical working capacity of this fermentation tank? **A**: The working capacity ranges from 5,000 to 30,000 liters, depending on the specific model and configuration. Always confirm the exact capacity with the manufacturer for your intended production scale. ### Q: What materials are used in the construction? **A**: The tank is made of AISI 316L stainless steel, with food-grade silicone seals and polyurethane insulation. These materials ensure corrosion resistance, hygiene, and thermal efficiency. ### Q: What temperature range can the tank maintain? **A**: The operational temperature range is 4–60°C, allowing for different yogurt fermentation profiles. The typical fermentation temperature is 40–45°C, but the system can be adjusted as needed. ### Q: What standards are referenced for pressure and safety? **A**: The pressure rating and operating pressure reference GB 150, a Chinese pressure vessel standard. The surface finish references ISO 4287, and the power supply references IEC 60038. These standards are for verification; compliance must be confirmed with the manufacturer. ## 6.
