What are the main ingredients of dry ice?

The main component of dry ice is carbon dioxide.

The history of dry ice can be traced back to 1823, when Faraday and Deeby in England liquefied carbon dioxide for the first time. Later, in 1834, Chirolet in Germany successfully produced solid carbon dioxide. However, it was limited to research use at that time and was not widely used.

Carbon dioxide is invisible. In fact, it is not (carbon dioxide) smoke, but (water) mist. When carbon dioxide changes from solid to gas, it absorbs a lot of heat, causing the temperature of the surrounding air to drop very quickly. .

As the air temperature drops, its solubility in water vapor becomes smaller. The water vapor undergoes a liquefaction reaction, releases heat, and turns into small droplets, which is fog. This has the same meaning as the "white mist" produced by popsicles in summer. They are all small water droplets, not other gaseous substances.

Extended information

Dry ice cleaning does not require cooling and mold disassembly , avoiding the corrosion and corrosion of molds caused by chemical cleaning methods Damage, mechanical damage and scratches to the mold caused by mechanical cleaning methods, and repeated loading and unloading leading to a decrease in mold accuracy. The key is that the two most time-consuming steps of disassembling the mold and waiting for the mold to cool down can be eliminated, which can reduce downtime by about 80-95%.

Benefits of dry ice cleaning: Dry ice cleaning can reduce downtime; reduce equipment damage; extremely effective cleaning of high-temperature equipment; reduce or reduce the use of solvents; improve worker safety; increase maintenance efficiency; reduce production Downtime, reduced costs, and improved production efficiency.

Dry ice can successfully remove baking residue, gummy substances and grease in the oven, as well as unbaked fresh product mixtures. Effectively clear ovens, mixing equipment, conveyor belts, molded products, packaging equipment, oven racks, hobs, containers, rollers, freezer inner walls, biscuit grates and other equipment.
