How to make and produce dry ice? The production of dry ice is achieved by reducing the pressure of liquid CO2, causing 60% liquid CO2 evaporates and absorbs a large amount of heat to become gas, resulting in the rest 40% liquid CO2 reduces temperature to become snow-like solid, known as dry ice.
Dry ice is solid carbon dioxide CO2, which is an odorless white solid in the form of dry ice powder, particles and blocks. The temperature of dry ice is minus 78.5 degrees Celsius. Under normal temperature and pressure, dry ice directly sublimates into CO2 gas, with an expansion rate of about 800-1000 times, it is widely used for home, commercial and industrial purpose in the entertainment, cold storage and dry ice cleaning. There are mainly three methods to make dry ice:
1. Home-made dry ice by carbon dioxide fire extinguisher and cloth bag
Prepare a cloth bag and place it over the outlet of the CO2 fire extinguisher. Turn on the fire extinguisher switch, and a small amount of white "snowflakes" will form in the cloth bag near the nozzle, which is dry ice. However, the amount is very small.
2. Manually-made dry ice by carbon dioxide steel cylinder and small dry ice maker machine
Buy liquid CO2 in gas shop or station, and usually food grade CO2 steel cylinder will be offered. Connect CO2 steel cylinder with mini dry ice maker S01 or small dry ice machine S02 which are sold at westech68.com, open the control valve, and dry ice will be produced. Low cost, easy to operate, suitable for cloud and fog effects in hotels, restaurants, bars, and clubs, low-temperature testing in laboratory and mechanical cold assembly at mechanical factory.
3. Automatically-made dry ice by carbon dioxide tank and full auto dry ice making machine
Buy liquid CO2 in gas station or company, make sure the liquid CO2 container is CO2 dewar bottle or tank not CO2 steel cylinder. Buy full automatic dry ice machine at westech68.com where there are small, medium and big capacity dry ice pellet maker and dry ice block machine Connect CO2 dewar bottle or tank with dry ice pelletizer or dry ice block maker, open CO2 valve, turn on dry ice machine, high density dry ice pellets or blocks will be produced. The dry ice made by this way is of high quality, very suitable for cloud and fog effects in catering and entertainment industries, refrigerated cold-chain transportation, industrial dry ice cleaning and industrial dry ice sales etc. For more information please contact +8618882125191, thanks.
