Abstract

PURPOSE:To miniaturize the device and to improve the production efficiency by carrying out the synchronized reciprocation of the right and left cylinders having upper and lower open ends on the base plate to which a central compressing gadget and a left and a right cover plates are alternatively connected. CONSTITUTION:The cylinders 4L, 4R having upper and lower open ends are provided on the base plate 3 consisting of a compressing stage 1 and the left and right snow growing stages 2, and are reciprocated together so that the former moves between the stages 1 and 2L the latter between the stages 1 and 2R. The compressing gadget 5 and the cover plates 6, 6 for cylinder are alternatively connected with the cylinders 4L, 4R. For instance, liquid CO2 is injected from the nozzle 7 provided to the cover plate 6 into the cylinder 4L to generate dry ice snow, and gaseous CO2 generated is allowed to flow out through the gas vent 15 of the plate 3. At the same time, the snow formed in the cylinder 4R is compressed and solidified by the compressing gadget 5, and the product is taken out from the taking-out opening 17 of the plate 3.

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.
