Description

Technical Field

[0001] The utility model belongs to the technical field of food processing, and in particular relates to a powder spraying device for food processing. Background Art

[0002] When processing and packaging food, for foods with high viscosity (such as glutinous rice products), it is generally necessary to spray a layer of cornstarch on the surface of the food before packaging. The food is placed in the packaging box and is sprayed with powder by the powder spraying device as it is transported on the conveyor belt.

[0003] Traditional powder spraying devices have some problems during the spraying process. One of them is the instability of the material tray, which may cause the tray to move unexpectedly, thus affecting the uniformity and accuracy of the powder spraying. At the same time, after the powder spraying, some powder will cover the packaging box and the powder will fly, which will cause waste on the one hand and affect the cleanliness on the other hand, making it inconvenient for subsequent packaging. For this reason, we designed a powder spraying device for food processing to provide another technical solution to the above technical problems. Utility Model Content

[0030] Both ends of the bottom of the vertical lifting plate 17 are fixed with vertical polished rods 19, and the outer side of the vertical polished rods 19 is slidably connected with a transverse support plate 20.
