The housing 24 is provided with a feeding opening communicating with the roasting cavity in the roasting utensil 21. The operating assembly is mounted on the housing. The operating assembly, the color sensor 23, the first motor 241, and the heating assembly are electrically connected to the circuit board. The operating assembly can be a roasting switch provided on the housing to start and stop the roasting device. Specifically, the roasting device 2 can be mounted on the upper part of the grinding device 1. The roasting utensil in the roasting device communicates with the coffee bean feeding opening of the grinding device through a discharging structure. The heated and roasted coffee beans in the roasting utensil can enter the grinding chamber of the grinding device through the discharging structure.

[0022] In the embodiment, the upper part of the roasting utensil 21 is open. The housing includes an upper cover for covering the opening. A color sensor is mounted on the bottom of the upper cover to sense the color information of the coffee beans in the roasting cavity below. An openable discharge opening 211 is provided on the bottom of the roasting utensil 21. A discharge channel is provided on the lower part of the housing to communicate with the discharge opening. A discharging slope is provided on the bottom wall of the roasting utensil to incline towards the discharge opening. The coffee beans in the roasting utensil are stirred and rolled by the stirring element to be heated. After roasting is completed, the coffee beans can roll along the discharging slope into the discharge opening and then enter the grinding device.

[0023] In the present embodiment, the stirring assembly further comprises a lifting structure 235, the stirring member 242 comprises an axially selectable stirring shaft 2421, a blade 2422 arranged on the stirring shaft, and a cover member 2423 mounted on the bottom end of the stirring shaft, the lifting structure is connected with the stirring shaft and can drive the stirring assembly to switch between the open state and the closed state. When the stirring assembly is in the closed state, the cover member covers the discharge port to prevent the coffee beans in the roasting vessel from entering the discharge port 211. When the stirring assembly is in the open state, the cover member does not cover or does not completely cover the discharge port, so that the coffee beans in the roasting vessel can enter the discharge channel through the discharge port.

[0024] In the present embodiment, as shown in the accompanying drawings, Figures 3-4 The lifting structure 235 comprises a second motor 2351, a transmission screw rod 2352 connected with the output shaft of the second motor 2351, and a sliding seat 2353 connected with the transmission screw rod 2352.
