Gas baking with charcoal fire baking with infrared baking
According to the different heat sources used, the baking of coffee can be divided into gas baking, charcoal fire baking and infrared baking. One of the most commonly used is gas baking, the temperature is controlled between 200 Mel and 300 degrees Celsius, and the temperature should be adjusted from time to time according to the need.
Most baking stoves use gas, the temperature is about 290 degrees, in the first 5 minutes, the free water is evaporated. The remaining water is then squeezed out of the beans (the process produces a "crackling" sound "fluffy" sound.
When the coffee beans reach about 200 degrees, they turn dark brown and begin to produce oil, a process called high temperature decomposition. At this time, the decision made by the coffee baker in the operation is very important, because if the baking time is too often, the coffee beans will be destroyed.
Commercial baking furnaces mostly use large machines. Generally, it is a cylindrical container with a diameter of more than two meters, with a heat source at the bottom, and a mixing tool inside the container constantly stirring the coffee beans. at the same time, the container containing the beans is easy to rotate, so that the coffee beans are heated evenly, and the coffee beans rotate along the spiral groove in the drum. When it reaches the trough low, it begins to bake. This expensive machine is used only when baking a large number of coffee beans.
Professional bakers may use a special barbecue. It is generally bulging, rotating horizontally, the fire is located in the lower part, and has an exhaust fan to drive away the smoke.
