Abstract

PURPOSE:A mixture of dry ice and a liquid which is prepared by spraying the liquid into liquefied CO2 is compressed for granulation whereby particles of dry ice-ice mixture of smooth surfaces and a long life. CONSTITUTION:Liquefied CO2 is led from the tank 2 through pump 3 to snowmaker 1 and sprayed downward from the top of the maker 1. At the same time, the water in the tank 4 is sent through a high-pressure pump 5 inside the snow- maker 1 and jetted downward from the lower position than the CO2 spraying so that the water jet is covered with atomized liquid CO2. A part of the liquefied CO2 is expanded adiabatically and the vaporization heat and sublimation heat are utilized to form snow 6 as a mixture of dry ice and ice, then the resultant snow is granulated. Thus, the dry ice is coated with ice on its surface to have luster and hardness enough to be used for polishing.

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method of combining dry ice and ice to produce particles of dry ice and ice that are used for surface polishing of objects to be polished such as steel plates, or for cooling foods.

For example, carbon dioxide gas (carbon dioxide gas) is pressurized at low temperature to produce liquid carbon dioxide (liquefied carbon dioxide) (LCO2).
Then, this liquefied carbon dioxide gas is adiabatically expanded to form a snow-like solid (snow dry ice) by the heat of vaporization and sublimation, and a small amount of liquefied carbon dioxide gas is added to this snow dry ice and pressurized to create a large lump of dry ice. There is a method of crushing this lump of dry ice with a crusher or the like to obtain dry ice particles, a method of pressing the snow dry ice from above with a press device to form pellets, or a method of turning the snow dry ice into pellets by pressing it from above with a press device. There are methods such as putting the material into a rotary extruder, compression molding it, and extracting it as a pellet.

However, in the method of crushing dry ice of the same size 9 with a cracker/jar or the like to granulate it, the large chunks of dry ice are crushed into powder, resulting in a poor yield of about 20%. In addition to being expensive, it must be stored as a solid until it is crushed, so it cannot be stocked for a long period of time. In addition, dry ice pellets obtained by pressing snow dry ice into pellets or pelletizing with a rotary extruder have a rough surface that looks like frost, and the surface is soft. Therefore, when used for polishing, it can be said that the cleaning effect cannot be fully demonstrated.

The present invention fundamentally corrects the problems that may occur when using only dry ice particles, hardens the surface, and reduces the consumption of dry ice particles even at temperatures higher than about -80°C. It was done for the purpose of
When making dry ice granules, a mixture of snow-like solid carbon dioxide and snow-like powdered ice is made, and this is compressed or extruded to make mixed granules of dry ice and ice. This eliminates roughness, and the powdered ice particles mixed with dry ice inside the dry ice particles prevent sublimation of the dry ice, making it possible to create dry ice particles with a long life.

As described above, according to the present invention, when making dry ice particles, a new method is adopted in which liquid is mixed with liquid carbon dioxide to make mixed snow, and the mixed snow is compressed and granulated to make dry ice. Since the particles are a mixture of dry ice and ice, the surfaces of the obtained particles are covered with liquid ice, making them shiny and hard. When used as a coolant, at a temperature of 1, at which the ice on the surface melts, the ice on the surface causes the internal drying to occur. It has the excellent effect of not consuming ice cream particles and can be used for a long period of time.Also, when making mixed snow, since liquid carbon dioxide and liquid are mixed, solid Compared to mixing, the mixing ratio can be changed arbitrarily and easily, and since dry ice is stored in a liquid state in the primary storage tank until granulation, dry ice is not handled in a solid state, so it can be kept in stock indefinitely. can.
