APPARATUS MANUFACTURING DRYICE NUGGET AND DRYICE NUGGET

摘要

The present invention relates to a dry ice nugget manufacturing apparatus and a dry ice nugget including a variable piston corresponding thereto and reducing a pressure space in a cylinder so as to increase the pressing force in the cylinder by injecting liquefied carbon dioxide, and to be liquefied into the cylinder. A dry ice manufacturing apparatus in which carbon dioxide is injected and the injected liquefied carbon dioxide is solidified inside the cylinder and accumulated in the cylinder, and the solidified and accumulated liquefied carbon dioxide is pressurized in the cylinder, comprising: a first case and a second case; a cylinder having a pressurized space therein by contact between the first case and the second case; a supply part connected to the cylinder so as to be connected to inject liquefied carbon dioxide into the cylinder, and connected to a case disposed on the front side of the first case and the second case in the pressing direction; and a piston which moves from the second case side to the first case in the cylinder and presses the pressurizing space, wherein the piston includes a fixed plate having a pressurizing support surface facing the pressurizing direction in the cylinder; a variable plate connected by a fixed plate and a connecting pin, positioned around the vertical variable portion and the vertical variable portion that can be moved in the pressing direction, and including a laterally variable portion that can be moved laterally based on the pressing direction; and an elastic body elastically deformed in the pressing direction between the fixed plate and the variable plate, wherein the lateral deformable part includes a first interlocking part and a second interlocking part in contact with the cylinder inner wall, and as it moves in the pressing direction, the inner wall of the cylinder When the width is reduced, the pressing area is reduced, the first interlocking part and the second interlocking part press the up-down movable part, and the up-down variable part is pressed by the side variable part, and the dry ice manufacturing apparatus is elastically moved to the pressing surface side. provided
