The invention has the main body discharge port formed at the lower end for discharging the corn Kernels slot is formed, the formed scratch the skin on the top to receive a supply of corn Kernels choice after step; Hoisting frame of a pair of said inlet and spaced a predetermined interval from the upper end coupled to the upper surface of the main body, formed in a direction perpendicular to the main body; The hopper fixed to the lower end of the platform; But located in the lower portion of the hopper, a conical rotary body intended to scratch the corn Kernels instructions from the hopper; A fixed axis of rotation to the bottom center of the rotating body; A driven pulley coupled to the lower end of the rotating shaft; Belt and the drive pulley for transmitting the power to the driven pulley; The drive pulley is axially coupled drive motor provided on the outside of the main body; jidoe consists, such that the rotor there is a plurality of circular edge forming a predetermined interval in the lateral direction, only once projected on the outside of the entire tooth of the circular edge that for providing a scratch-forming apparatus of the configuration corn Kernels skin is, the present invention is to located in the center of the corn Kernels during steaming process of the later corn Kernels by providing a device for betting the scratch, that is wound on the skin of corn Kernels starchy to the penetration of steam so easily achieved to increase the luxury also with also shorten the time of the steaming process, the corn Kernels ripe by the penetration moisture vapor to the interior of the corn Kernels during compression process after the steaming process is squeezed is easily made Not only it is very useful to inventors to obtain a good quality of appyeon.
