A plurality of semi-circular flour circular grooves are correspondingly arranged on the mold disk and the cover mold, penetrating holes are arranged on the top and the bottom surfaces of the flour circular grooves, and round balls which are made of flour and water are put in the flour circular grooves. The upper part of the cover mold is additionally provided with a needle holder which can move up and down reciprocating way, and the bottom surface of the cover mold is provided with a plurality of through needles. When the needle holder moves downwards, the through needles are penetrated through the penetrating holes of the cover mold, and the hard flour round balls are punched. After the penetrating holes of the flour circular grooves are penetrated through, the needle holder moves upwards. Macaroni circles which have though holes are formed when the hard flour round balls are penetrated through by the through needles.
