To solve the problem of requiring an inexpensive method to return to a snow shape, since snow-shaped seawater ice becomes a large snow ice mass by consolidating in a vessel when transporting the snow-shaped seawater ice to a distant place, though a demand of the snow-shaped seawater ice increases as a raw material of seawater sherbet being a coolant of raw fish.

A recess-projection is arranged in an inclined part of an angle-shaped tool with the lateral width center as a top part, and is also bent in a " V " shape in a central part. In a snow shaving machine, the snow ice mass is scratched off from a surface in this recess-projection part, and a scratched-off snow ice piece is crushed by a rotary blade. A door for carrying in the snow ice mass is arranged in this ice shaving device, and an L-shaped carrying-in stage is also added, and the upper side of the door and an upper piece of the carrying-in stage, and also the lower side of the door and the contour of the ice shaving device, are respectively rotatably joined. Thus, an emptied vessel is returned to an original carrying-in stage position by sending out the inside snow ice mass in the device by automatically overturning the vessel lowered on the carrying-in stage only by opening-closing operation of a carrying-in door.
