Description

Technical Field

[0001] This utility model relates to the technical field of powder coating machine tools, specifically to the powder blowing mechanism of the powder coating machine fan. Background Technology

[0002] A coating machine is a processing machine used to coat the outer wall of food during food processing. For example, crispy pork, chicken legs, and popcorn chicken generally need to be coated with flour before frying. After coating food with flour, the surface of the food is prone to excessive powder adhesion, which creates waves and wastes the powder. Furthermore, it causes the powder to fall off severely in subsequent processing steps, affecting product quality.

[0003] A prior art patent, CN209017810U, discloses a machine base containing a vibrator. A material tray is mounted on the vibrator, and the tray contains a spirally upward-facing material coating and conveying channel. A spirally downward-facing material screening and output channel, connected to the output end of the material coating and conveying channel, is located on the outer wall of the tray. A stepped, spirally downward-facing screening screen is mounted on the bottom plate of the output channel. A powder receiving trough is located below the screening screen, and the side wall of the material receiving trough has a powder outlet connected to the receiving trough for allowing powder to fall into the bottom of the tray. This coating machine is not only compact but also convenient for coating items with powder.

[0004] However, as this method was put into production and used, shortcomings of the device gradually emerged:

[0005] First, the existing fan structure of the breading machine, while ensuring a constant fan speed, makes it difficult to adjust the airflow, thus failing to meet the needs of breading different foods.

[0006] Secondly, the existing wind turbine structure, limited by its fixed structure, makes it inconvenient to disassemble and clean, reducing maintenance efficiency.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
