1, stainless steel smokeless electric grill is better, more durable than iron, and not easy to rust, and fast heat transfer. Grill plate coating selection, electric grill mainly silicone oil and DuPont Teflon two coatings, recommended DuPont Teflon coating of the grill plate, silicone oil at high temperatures easy to stick to the oil leads to not easy to clean, and especially easy to stick to the food Teflon has a corrosion-resistant, water-wet, non-stick oil, high temperature characteristics, the use of such a coating of the grill plate is safe and non-toxic, easy to clean. Be aware of the silicone oil coating and Teflon coating is very similar in appearance, observe the baking dish with or without DuPont certification logo stickers.

2, heating tube selection: heating tube on the market is very diverse, the material is mainly cast iron, stainless steel, etc., to buy electric grill to pay attention to the design life of the heating tube, power, material and so on. Good heat pipe should be made of stainless steel, due to long-term high-temperature environment, cast iron heat pipe will gradually absorb moisture in the cooling process rust, which in turn affects the heating efficiency.
