Dry ice (dry ice) as the carbon dioxide in the solid state. Call one of the names that the solid carbon dioxide solid carbon dioxide prepared from the carbon dioxide come through the extrusion process and cool down. Under high pressure into liquid carbon dioxide. And reduce the pressure down fast by spraying liquid carbon dioxide to the atmosphere pressure. The result is that the flake ice like snowflakes. Then the compression format and various sizes according to the purpose of the application of the รูปแบบเป็นก้อน (block) half size to 15 kg. A sheet (slice) ranging in size from half to 1 kilo bars (pellet) 3 mm diameter 9 mm and 15 mm. And so on.Dry ice different from ordinary ice.Dry ice are similar to the ice in general is solid, no color, and as the cold but dry ice is different from ordinary ice.1. Temperature, dry ice has a temperature lower than normal, which ice cold - 79 while ice normal temperatures around 0.2. To change status. When the dry ice and ice plain placed at room temperature (about 25 - 30). It was found that the temperature of the ice sublimation become carbon dioxide without melting the melting liquid. The ice will melt, while the ordinary water. Which is what the melt into a liquid. That is why it"s called "dry ice."3. Cold dry ice for cooling than ordinary ice to 2 or 3 times compared by weight or volume rate to the ice plain.Advantage of dry ice.From the properties of dry ice is cold temperatures to - 79 and prevent the melting and the ice using several aspects. Especially in low temperature as desired: in the food industry. A conserved in the process of production and transportation, for example, used to soak the ice fish or meat of other animals used in frozen ice cream, milk. Bakery, sausage, used to soak แข็งผั.
