The scraper 73 presses the upper surface of the lower cutter 50 ) Powder 2 can be removed so that the pulverized powder can be easily moved toward the powder outlet 13.

A method of pulverizing using a dry food pulverizer according to embodiments of the present invention having the above structure will be briefly described with reference to FIG.

First, after the grinder is operated, the worker inserts the work material 1 for grinding into the hopper 30 (step S11).

The workpiece 1 inserted into the hopper 30 is supplied to the rotation induction space 11 of the housing 10 through the induction pipe 20 (step S12), that is, between the upper cutter 40 and the lower cutter 50 (Step S13).

The upper cutter 40 and the lower cutter 50 are then rotated in opposite directions so that the workpiece 1 is moved to the edge through the centrifugal force and cut through the cutters 43 and 53, And pulverized into a powder 2 (step S14).

At this time, by blowing high-pressure air through the air injector 60, the work material 1 is quickly pushed to the edge of the upper cutter 40 and the lower cutter 50 (step S15).

At the same time, the powder eliminator 70 mounted on the upper cutter 40 and rotated at the same time removes the powder pressed on the upper surface of the lower cutter 50 (step S16).

Then, the pulverized powder 2 which has moved to the powder outlet 13 through the air is collected in the receptacle 90 through the powder outlet 13 (step S17).

Although the present invention has been described in connection with the exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood that various modifications and changes may be made without departing from the scope of the appended claims.
