Research on coffee roasting technology:

A series of chemical changes occur in the process of baking. After about 15 minutes of baking, the green coffee beans lose moisture, turn yellow, and then burst like popcorn. After this process, the coffee beans will double in size and begin to show a light brown after stir-frying. After this stage is completed (after about 8 minutes of baking), the calories will be reduced. The color of the coffee soon changed to dark. When the preset baking degree is reached, cold air can be used to stop baking to achieve rapid cooling.
