Air fryers, as the “new darling” of modern kitchens, have won the love of many consumers with their healthy and convenient cooking methods. So, a smart small household appliances, is made of what materials? Let’s unravel the mystery of it.

The production of air fryers involves a variety of materials, which are mainly divided into shell materials, inner liner materials, heating elements and control panels.

1. Shell material: stainless steel, plastic, paint:
2. Inner liner material: ceramic inner liner, enamel inner liner, non-stick coating
3. Heating element

• heating tube is generally made of stainless steel or nickel-chromium alloy, with high temperature resistance, good thermal conductivity characteristics.
• Heating pan: Some air fryers use a heating pan design, similar to the heating tube material.

4. Control Panel

• Plastic: light, easy to form, but moderate resistance to high temperature.
• Metal: high temperature resistance, wear resistance, but the cost is higher.

5. Common test items

• Heavy metal test: test the content of lead, cadmium, mercury and other heavy metals to ensure that it does not exceed the national standard.
• Plasticizer test: Detect the content of plasticizers such as phthalates to prevent migration to food.
• high temperature resistance test: simulate high temperature environment, detect material deformation, discoloration, release of harmful substances and so on.
• Non-viscosity test: test the wear resistance, non-viscosity and easy cleaning of the coating.
• Corrosion resistance test: simulate acid, alkaline and other corrosive environment to test the corrosion resistance of the material.
• Microbial detection: Detect whether there are bacteria, mold and other microorganisms on the surface of the material.

6. Relevant certifications

• CB certification (designed to reduce the need for repeated testing and certification of electronic products through mutual recognition among member states, meaning that the product has met international safety standards.)
• CE certification (indicating that the product meets the health, safety and environmental protection requirements of the European Union). Is a necessary condition for the free circulation of products in the European market.
• EMC certification (electromagnetic compatibility certification ensures that the product neither produces nor is affected by electromagnetic interference in the electromagnetic environment, and can work normally)
• ETL certification (indicating that the product has passed the electrical safety standard test in the United States, Recognized in the U.S. and Canadian markets)
• ROHS certification (indicating that the product is free of harmful substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE)), etc.
