[0031] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0033] Specifically, first, the feed inlet cover 1 and the partition 3 are opened, and the coffee beans are poured into the storage box 2 from the inlet. The coffee beans enter the upper cover 8 and the lower cover 5 along the pipeline, and then the feed inlet cover 1 and the partition 3 are closed. Then, the motor 12 and the heating tube 19 are started. The driving end of the motor 12 rotates to drive the stirring rod 15 to rotate. The stirring rod 15 rotates to drive the stirring blade 16 to start stirring the coffee beans. Then, the feed inlet cover 1 is opened, and a proper amount of coffee beans is poured into the storage box 2. Since heat energy and hot air are generated during baking in the baking oven, the exhaust fan 13 is started at this time. , the hot air in the roasting box is drawn into the outlet pipe 9, and the hot air enters the storage box 2 through the outlet pipe 9, so as to preheat the coffee beans in the storage box 2, and then the hot air returns to the roasting box through the ventilation pipe 17, thereby forming an internal air circulation. When the coffee beans in the roasting box are roasted, the discharge port cover 6 is opened to take out the roasted coffee beans, and then the discharge port cover 6 is closed and the partition 3 is opened to send the preheated coffee beans into the roasting box, and the cycle is repeated in sequence to repeatedly recycle the generated heat energy, thereby achieving the effect of energy saving and environmental protection.

The hot air in the box is drawn into the outlet pipe 9, and the hot air enters the storage box 2 through the outlet pipe 9, thereby preheating the coffee beans in the storage box 2, and then the hot air returns to the roasting box through the ventilation pipe 17, thereby forming an internal air circulation. When the coffee beans in the roasting box are roasted, the discharge port cover 6 is opened to take out the roasted coffee beans, and then the discharge port cover 6 is closed and the partition 3 is opened to send the preheated coffee beans into the roasting box. When the machine needs to be cleaned, the limiter 18 is removed, and then the upper cover 8 is slid and removed along the groove to clean the inner wall of the machine.
