The fixing nut 324 is provided with an internal thread, and the outer surface of the column 330 of the material discharge baffle 33 is provided with an external thread. The fixing nut 324 is threadedly connected with the column 330, so that the stirring portion 32 is fixedly connected with the material discharge baffle 33 in the axial direction.

[0072] Please refer again Figure 5 and Figure 7, the material removal baffle 33 rotates with the shaft 320. In order to increase the smoothness of the material removal baffle 33 during the rotation process, the material removal baffle 33 and the barrel 31 are respectively provided with a guide structure. In one embodiment, a convex rib 311 is provided on the inner surface of the barrel 31, and the plate body 331 of the material removal baffle 33 is supported on the convex rib 311 and rotates along the convex rib 311.

Fig.10 In the illustrated embodiment, the notch 102 is provided on the housing of the first component 11 .

[0096] Please refer again Figure 3 and Figure 4 In one embodiment, the food processor 100 further includes an air supply component 40 that can generate and deliver hot air, and the air supply component 40 is used to deliver hot air into the material barrel 31 to bake the food.

At this time, the unloading baffle 33 is in a closed state, and the stirring paddle 321 can be used to stir the food in the barrel 31. When the unloading baffle 33 is opened, the stirring paddle 321 remains still during the unloading process, thereby realizing the one-way rotation of the stirring paddle 321.

When a one-way bearing is used, the first sub-member and the second sub-member are the inner ring and the outer ring of the one-way bearing respectively. When a ratchet mechanism is used, the first sub-member and the second sub-member are the one-way ratchet and the pawl respectively, which will not be described in detail here.
