The warm oil pan is commonly known as 30% to 40% hot, and the oil temperature is 70- 100 degrees, indicating that the oil level is calm, there is no smoke and no noise.

Hot oil pan, commonly known as 50% to 60% hot, oil temperature1170 degrees, oil level does not smoke, turn to the middle.

The king oil pan is commonly known as 70% to 80% hot, the oil temperature is 180-220 degrees, the oil level is light smoke, the oil level is calm, and there is noise when stirring with a spoon.
