Coffee roasting process
In the process of roasting coffee beans, as the roasting time lengthens, coffee beans will go through ten processes. By understanding the process, we can better understand the correlation between coffee flavor and it.
Green raw bean stage
When you start baking, the temperature rises slowly, and the coffee remains light green, which is not suitable for drinking.
Yellow dehydration stage
With the increase of roasting time, the color of coffee slowly changes to light yellow, with the aroma of grass, but the coffee beans at this stage are still not suitable for drinking.
Fueling stage
The water in the coffee beans began to evaporate, producing water vapor.
Primary explosion stage
At this point, you will hear a crisp popping sound. The sugar content of coffee is about to begin caramelization, which is usually used in cup testing.
Light baking stage
At the beginning of the explosion, the coffee beans were in a light baking state. What we generally call shallow culture is this time, and the coffee beans at this stage are already suitable for drinking.
Moderate baking stage
After a caramel reaction of about degrees Celsius, the oil begins to ooze, the beans begin to swell, and the coffee is in a medium culture state.
Middle and deep cultivation stage
Between moderate roasting and second explosion, the taste of coffee is almost sour, and the concentration will be more intense, which is generally called medium-deep culture.
Second explosion stage
The second popping sound is louder than the first one. At this time, the coffee is in a state of deep roasting, which is generally called deep culture.
French baking stage
The color of the coffee has become very dark and close to black, the sugar is exhausted, it begins to smoke, and the structure in the bean body disintegrates, which is called French roasting.
Coke burning stage
Coffee beans have been completely burnt, can not drink any coffee flavor, can no longer drink.

The advantages and disadvantages of the flat knife: the flat knife grinder is composed of the upper and lower cutter heads, and the base is fixed on the motor.

When the coffee particles fall from the middle, the knife head rotating at the bottom will spin the coffee beans to the outside and push the coffee beans into the tooth cutter part for grinding.
