If you deviate from this center, it is impossible to get good quality coffee. The obvious signs of this stage are the first explosion and the second explosion.

At this stage, the temperature starting point must be controlled above 180 degrees, which is the center of the whole baking process. If you deviate from this center, it is impossible to get good quality coffee. The obvious signs of this stage are the first explosion and the second explosion. It can also be called the bursting stage of coffee beans. This stage is an important stage to generate various flavors of coffee. The size control of firepower, furnace temperature and exhaust control are the key.

Generally speaking, medium firepower should be maintained before the completion of the first explosion, and the firepower should be determined according to the required baking degree after the completion of the second explosion. The firepower must be reduced before entering the second explosion in shallow baking and 10-20 seconds after entering the second explosion in deep baking.

After entering the baking stage, the amount of smoke produced in the furnace is very large, so it is necessary to increase the exhaust volume, which is suitable from medium to high grade.

Cooling editing

When the coffee beans in the furnace reach a satisfactory roasting degree, they must be cooled immediately. Quick cooling is the best, which can keep the best baking degree. For deep baking or summer work, you can use a suitable fan as an assistant.
