Roasting and preservation of coffee beans? How to bake coffee beans

There are many ways to roast coffee. I'll just say a relatively simple one.

Before the coffee is roasted, the coffee should be treated by natural method or washing method, and then the coffee can be roasted. First, it is baked in a large rotating barrel. After 5 to 7 minutes of intense heat, the water in the coffee beans gradually evaporates. At this time, the coffee beans begin to turn yellow and produce a strong aroma. Eight minutes later, when the "first burst" began, the coffee beans doubled in size and crackled. At this time, their color is light brown. After baking in a container for 10 to 11 minutes, the coffee beans become darker and darker. When roasted for 11 or 15 minutes (depending on the type of coffee), all the flavors of the beans are released, and most of these flavors are balanced. At this time, the "second explosion" begins, which marks the end of the roasting process of coffee beans. Just move the coffee beans to the cooling plate.
