Description

Powder Dreger {Powder dredger}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder dresser, and more particularly, to a powder dresser device for decorating beverages such as coffee, cocoa, milk, and tea with powder.

A method of draining a powder such as a cinnamon powder, a cocoa powder, a green tea powder, a vanilla powder or a chocolate powder is used to put a certain pattern of pictures or patterns on a beverage such as coffee, cocoa, milk or tea or a foam thereon . For example, a milk bubble is directly sprayed on a coffee, or a steam milk is put on a coffee, a milk foam is put on the coffee bubble, and the powder is drained in a certain pattern or pattern on the milk foam, . At this time, a pattern screen plate having holes of a predetermined pattern is used to apply the powder in a predetermined pattern. When powder is sprayed on the screen, the powder passing through the holes of the patterned screen plate is applied onto the milk foam in the form of the holes. However, since the pattern screen plate completely separated from the tool for applying the method powder is used, it is difficult to apply the powder in a desired pattern, inconvenient to use, and inconvenient handling and storage.
