In addition to arranging a nozzle and a preload piston that moves up and down inside the cylinder, a compression piston is placed in the lower cylinder, and after the dry ice snow generated in the upper cylinder is lightly compacted with the preload piston, the shutter is opened to compress the dry ice snow. The compacted dry ice block is fed into the lower cylinder, where it is compressed and solidified at a high density, and the compression work in the lower cylinder and the dry ice snow generation work in the upper cylinder are combined. I'm trying to do it in parallel.

アイススノーを生成することができる。(Function) The present invention is equipped with two cylinders formed in a top and bottom open shape, one compression tool, two lid plates, and a series of bottom plates.
By arranging two lid plates in symmetrical positions centering on the compression tool and fixing liquid carbon dioxide gas jet nozzles to each lid plate, the location of the compression tool can be set to the compression stage, and the installation position of the lid plate can be set to the snow stage. The cylinders are formed in the compression stage and the snow generation stage respectively, and both cylinders are arranged in correspondence with the compression tool and one of the lid plates, and the cylinders are connected to the compression tool and the lid plate alternately. A gas vent is formed in the bottom wall at a location corresponding to the snow generation stage, and a product outlet is opened in the bottom wall of the compression stage. Since it is configured so that it can be moved in and out, the compression work at the compression stage and the dry ice production work at the snow generation stage are performed in parallel. Moreover, at this time, since a gas vent is formed in the bottom wall of the snow generation stage, the carbon dioxide generated during dry ice snow generation escapes from the gas vent, increasing the ejection pressure of liquid carbon dioxide and carbon dioxide. The pressure associated with the flow presses the dry ice snow, making it possible to produce dry ice snow that is free of gas components.
