Iron, stainless steel, various plastics, and the like can be used. As locations where the projections 6 are provided, for example, several locations can be provided at equal intervals along the circumference of the projection 4. Thereby, it is conceivable that the projection 6 has the function of crushing the clay-like substance in the groove 5 of the counterpart cylindrical rotating body 1 or discharging the crushed material in the groove 5 to prevent clogging. When the clay-like substance is crushed by the convex portions 4 of the cylindrical rotating body 1, the clay-like material is easily crushed into an elongated shape, but the crushed material formed into the elongated shape by the projections 6 is further shortened.

For example, when the cylindrical rotating body 1 is made of stainless steel, the scraper is preferably made of aluminum or plastic that is softer than stainless steel. The angle of the scraper blade is preferably 15 to 60 degrees,
As the angle of the blade is smaller, a crushed molded product having a shape closer to the concave portion of the rotating body is obtained, and as the angle of the blade is larger, a molded product shorter than the concave shape of the rotating body is obtained. When the angle of the blade is larger than 60 degrees, the blade of the scraper becomes a resistance, and it is necessary to increase the rotational power.
