Welcome!

The dry ice production exhaust CO2 gas recovery system is an eco-friendly, energy-saving unit designed to capture carbon dioxide gas emitted by dry ice making machines during production. The CO2 recovery plant employs a closed-loop process—comprising recovery, compression, purification, and liquefaction—to convert the exhaust CO2 gas directly emitted by dry ice machines back into liquid CO2 for reuse, thereby lowering production costs and reducing carbon emissions.

A dry ice blasting machine is an eco-friendly industrial cleaning machine that utilizes dry ice pellets as the cleaning medium, accelerating and spraying them via high-pressure compressed air to clean surfaces. Dry ice pellets are solid carbon dioxid produced by a dry ice maker machine, characterized by high density and an extremely low temperature of -78℃, which provides powerful cooling and freezing effects. Under normal temperature and pressure, dry ice sublimates directly from a solid to a gas without passing through the liquid phase, leaving behind no liquid residue or moisture.

A dry ice cleaner machine is an eco-friendly industrial cleaning machine that utilizes dry ice pellets as the cleaning medium, accelerating and spraying them via high-pressure compressed air to clean surfaces. Dry ice pellets are solid carbon dioxid produced by a dry ice pelletizer machine, characterized by high density and an extremely low temperature of -78℃, which provides powerful cooling and freezing effects. Under normal temperature and pressure, dry ice sublimates directly from a solid to a gas without passing through the liquid phase, leaving behind no liquid residue or moisture.

The conversion rate of a dry ice block maker machine—defined as the ratio of liquid carbon dioxide converted into solid dry ice—varies based on equipment technology, models, operating conditions, and measurement methods; there is no single fixed value. However, the industry-standard conversion rate generally ranges from 40% to 43%, while some high-end models or systems modified for enhanced performance can achieve rates between 50% and 80%. Specific classifications are as follows:

The dry ice pelletizer machine is a specialized dry ice maker machine designed to convert liquid carbon dioxide (LCO2) into solid carbon dioxide (dry ice). While structural details vary between dry ice pelletizer machine and dry ice block maker machine models, they all comprise the following five core functional modules:

Dry ice is solid carbon dioxide, due to its extremely low temperature (-78.5℃) and the property of direct sublimation (transitioning from solid directly to gas without leaving any liquid residue), dry ice is widely used across various fields. Its primary applications fall into the following six categories:

Dry ice making machines are ice maker machines that convert liquid carbon dioxide (LCO2) into solid carbon dioxide (dry ice). These dry ice production machines are classified based on dry ice shape, production capacity, level of automation, and equipment structure, as follows:

Dry ice maker machine is an industrial or commercial ice maker equipment designed to convert liquid carbon dioxide (LCO2) into solid carbon dioxide (dry ice). Carbon dioxide (CO2) exists in three physical states—gas, liquid, and solid—depending on temperature and pressure, dry ice is the solid form of carbon dioxide. The dry ice making machine does not itself produce carbon dioxide; rather, it is a device that alters the physical state of carbon dioxide and compresses solid carbon dioxide into various shapes.

Dry ice is solid carbon dioxide (CO2), not ordinary ice (ice formed from frozen water H2O). It is a white solid obtained by rapidly depressurizing liquid carbon dioxide. Its temperature at normal pressure is extremely low, at -78.5℃. Although it looks like ice, it does not melt into a liquid but sublimates directly into a gas, hence we call it "dry ice".

A liquid nitrogen dosing machine (also known as a liquid nitrogen injector) is an automated device designed to inject a precisely measured amount of liquid nitrogen into packaging containers—such as aluminum cans or PET bottles—after filling but before sealing. Its core operating principle relies on the rapid vaporization of liquid nitrogen within the container (where it expands to approximately 700 times its liquid volume) to achieve specific packaging and preservation effects.

A dry ice cleaning machine, also known as a dry ice blasting machine, is a professional cleaning equipment that uses compressed air to spray dry ice particles onto the surface of the cleaning object to achieve highly efficient cleaning purpose. Dry ice blasting cleaning does not use any chemical agents, will not damage the surface of the cleaning object, and leaves no additional residue. Dry ice cleaning is an ideal cleaning method.
