For example, crispy pork, chicken legs, popcorn chicken and other foods generally need to be coated with flour before frying. After the breading machine coats the food with flour, powder tends to adhere excessively to the surface of the food, causing powder waste and causing serious powder falling during subsequent processing steps, affecting product quality.

[0003] The prior art discloses a patent with announcement number CN213881726U, which includes a belt driven shaft, a conveyor belt, and a belt drive shaft, all of which are fixedly installed on the main body bracket, the conveyor belt is respectively connected to the belt drive shaft and the driven shaft, the drive motor is connected to the belt drive shaft, a hopper for holding powder is installed on the main body bracket, a material blocking roller is installed above the belt driven shaft, and the material blocking roller drive chain is respectively connected to the drive motor and the material blocking roller. The powder coating machine belt powder spreading device adopts a belt structure to convey powder. Since the belt is an overall plane conveyor, the powder can only be conveyed on the belt surface, and the powder will not fall into the gap between the mesh belt and cause damage to the powder particles, thereby reducing the powder breakage rate of large-particle powder, extending the use time of the powder, and reducing the impact of the powder size on the product appearance and taste.
