Description

Technical Field

[0001] The utility model belongs to the technical field of coffee beans, and more specifically, relates to a uniform heating device for roasting coffee beans. Background Art

[0002] Coffee bean roasting is a process of heating green coffee beans to develop and enhance their flavor and aroma. This process is a crucial step in transforming green coffee beans from their original state into the dark brown coffee beans we are familiar with. Coffee bean roasting not only changes its color but also significantly affects the taste, aroma, and texture of the beans. The coffee bean roasting process is usually divided into several stages. First is the "drying stage", in which the coffee beans are heated to about 100°C, moisture begins to evaporate, and the beans become dry. Then it enters the "Maillard reaction stage", where the bean temperature rises to about 150°C, and sugars and amino acids react to form complex flavor compounds, and the color of the beans gradually turns yellow and starts to turn brown. Then comes the "cracking stage", where the beans "burst" at about 200°C, releasing carbon dioxide and volatile compounds, and the aroma of the beans begins to significantly increase. Finally is the "development stage", which is the key stage in determining the final flavor of the coffee beans. The roaster controls the time according to needs to form specific flavor characteristics.
