The iron plate is made of gray iron melting with model casting, cast iron plate has a characteristic, when the temperature of the fire exceeds 200 ° C, the cast iron plate will emit a certain amount of heat energy, the temperature transferred to the food is controlled at 230 ° C, and the fine iron plate is directly the temperature of the fire to food. Avoid the potential effects of harmful chemicals. The heat transfer is uniform, the heat is moderate, and it is easy to combine with acidic substances in cooking, so that the iron content in food increases several times, so as to promote the new blood and achieve the purpose of blood supplementation. A large amount of iron absorbed by the human body comes from the iron plate, and the dishes fried with iron on the iron plate are easy to absorb by the human body, but only the cast iron plate can be incorporated into the iron element when cooking. Other disks are unlikely to allow the body to get the iron it needs. In addition, cooking vegetables in iron plates can reduce the loss of vitamin c in vegetables.
