In this way, the material to be cooked 43 can be cut and crushed by the cutting plate 33 having a simple structure.
When cleaning the cutting plate 33, unlike the case where a disc-shaped cutter is formed with a large number of small cutting blades, the risk of injury to the human body etc. is reduced, and the cleaning performance of the cutting plate 33 is also improved. Furthermore, since the structure of the cutting plate 33 is simplified, the cutting plate 33 can be easily formed, and therefore costs can be reduced.

In the above embodiment, the cutting plate 33 is formed into a substantially rectangular shape and the cutting edge 35 is linear. As shown in the figure, the cutting edge 3 has a substantially rectangular cutting plate 33 whose edge surface in the direction of rotation shown by the arrow is formed into a step-like uneven surface.

The inclined surfaces 46 and 46 are inclined downward to the position 20a where they are on the same plane. In this structure, as shown in FIG. 3, the material to be cooked 43 that is pushed through the push rod 42 by a person's hand is cut by the cutting plate 33 and after passing through the upper surface of the cutting plate 33, the material 43 is pushed in the direction of rotation. Since there is no step a/)< on the side edge 45 on the opposite side, the push rod 42 held by a person's hand does not move downward suddenly, and the inclined surface 46. With 4G, after the material to be cooked is cut by the cutting plate 33, it moves on the slope 46 and falls gently, and the material and the push rod 42 that presses it do not move suddenly.
Therefore, unpleasant vibrations are not transmitted to the hands of the person holding the push rod 42.

(Effects of the Invention) According to the present invention, the cutting plate, which is fixed to the upper surface of the rotating body and cuts and crushes the cooking material inputted from the cooking material input port, is formed of a thick and elongated sheet metal. Since the upper edge edge on the rotation direction side of the cutting plate is used as the cutting edge for cutting and crushing the material, the structure of the cutting plate can be simplified, and therefore there is no risk of injury to the human body etc. when cleaning the cutting plate. In addition, the cutting plate is easy to clean.
In addition, it is possible to reduce costs because it is easier to form, and if the punching burrs that occur on the side edges of the cutting plate during press forming are made into edge-shaped cutting edges, this cutting edge by polishing etc. The formation of the cutter can be omitted, and the cutter can be obtained at low cost.
