You care not only about how well the pot works, but also about the safety and health of your family's meals. This dedication is commendable. The hard anodized inner pot boasts exceptional durability. Its core advantage lies in the high-hardness, uncoated oxide layer formed on the aluminum alloy surface through a hard anodizing process. This layer possesses strong wear resistance, corrosion resistance, and scratch resistance, maintaining stable performance even after long-term use.
1. Hard Anodized Inner Pot: Structure and Process Determine Durability
Process Principle: The hard anodized inner pot utilizes aerospace-grade oxidation technology to generate a hard oxide film with a thickness of up to 1.6mm or ≥25μm on the aluminum alloy substrate. This process is a physical modification, independent of chemical coatings.
Wear Resistance Test: Even with repeated scrubbing with a steel wool pad, the surface will not show scratches or peeling, completely avoiding the risk of "paint peeling and food getting mixed in" common with traditional PTFE-coated pots.
Structural Strength: The thickened design (e.g., 1.6mm) significantly improves resistance to deformation, making it suitable for high-frequency, long-term stewing scenarios, especially for common Chinese cooking operations such as soup making and braising.
2. Lobe Electric Pressure Cooker: Actual Usage Performance Verifies Durability
Many Lobe electric pressure cookers feature a zero-coating hard anodized inner pot. User feedback shows that even after more than two years of continuous use with daily usage, the inner pot remains smooth and new, without peeling or discoloration.
Because there's no need to worry about coating aging, maintenance costs are low; cleaning can be done directly with a scouring pad, greatly extending the overall lifespan of the cooker.
