Welcome!

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.

The core principle of liquid nitrogen dosing machine is based on the physical property of cryogenic liquid nitrogen (-196°C) rapidly vaporizing and expanding at room temperature.  The liquid nitrogen dosing system drips a precise dose of liquid nitrogen into the packaging container, where the liquid nitrogen rapidly vaporizes and expands approximately 700 times, instantly expelling air from the bottle and achieving oxygen removal for preservation and pressurization to prevent collapse. It is commonly used to increase the hardness of PET bottled mineral water and edible oil, and preserve beverages and food.

The MINI Dry Ice Cleaner machine is a newly developed portable dry ice cleaning machine with a compact design and a weight of only 9 kg, it can be used conveniently and move flexibly in factory workshops, laboratories, or residential rooms.

In the automatic dry ice production by dry ice makers, the raw material supply is very important. The control valve for opening and closing liquid carbon dioxide supply is CO2 solenoid valve. Its working pressure is below 45 bar. Therefore, fully automatic dry ice production machine can only be connected to carbon dioxide storage tank or Dewar flask bottle with pressures below 23 bar. Connecting automatic dry ice maker to CO2 cylinder with pressures up to 100 bar will damage the CO2 solenoid valve.

Dry ice is widely used in food preservation, industrial cleaning, medical transportation and stage effects. However, dry ice production emits large amounts of carbon dioxide gas. The carbon dioxide recovery unit equipment can efficiently recover these carbon dioxide gas from dry ice making machine, significantly improving dry ice production efficiency and achieving resource recycling.

Dry ice cleaning machines, also known as dry ice blasting machines, is a highly efficient and environmentally friendly cleaning machine. They use high-pressure compressed air to accelerate dry ice particles and then spray them to clean objects. The high-speed -78°C dry ice pellets freezes dirt and breaks its adhesion, then instantly sublimate and expand, generating a powerful peeling force to remove dirt quickly and achieve efficient cleaning results. Dry ice cleaning is a physical cleaning method that is 100% chemical-free and requires no secondary treatment.

Common problems and solutions for dry ice making machines are as follows:

Pneumatic dry ice cleaning machine only uses compressed air as a power source and does not require electricity. It is composed of dry ice hopper, dry ice conveyor, air supply system, pneumatic control system, and injection system. It has three obvious advantages: safety, flexibility, and environmental protection. With a fully pneumatic design, the dry ice machine has no risk of electric sparks and can operate safely in flammable and explosive environments such as petrochemicals and dust workshops. It can also directly clean circuit boards, battery compartments, motors, and electric parts; without relying on power, it can also operate in field environment without electricity.

Dry ice cleaning is an environmentally friendly cleaning technology that uses dry ice (solid carbon dioxide) as a cleaning medium. The dry ice cleaning machine, also known as dry ice blasting machine accelerates the dry ice particles to hit the surface of the object through high-pressure airflow, and achieves efficient and non-destructive cleaning effects through the triple physical effects of low-temperature embrittlement, impact peeling and sublimation purge.

The principle of liquid nitrogen generator equipment is mainly based on air separation and cryogenic liquefaction technology, which uses physical methods to separate nitrogen from other gases in the air and cool it to liquid state.

Whether it is an industrial dry ice machine or a small dry ice maker, the core principle of dry ice making machine is that high-pressure carbon dioxide is cooled by rapid decompression to make part of the liquid carbon dioxide form solid dry ice. The following are the detailed steps and principles:

Dry ice cleaning technology, also known as dry ice blasting, is an industrial cleaning method that uses solid carbon dioxide (dry ice) pellets as the cleaning medium. Dry ice cleaning machine uses the thermal shock effect, mechanical impact force and expansion of carbon dioxide gas to remove dirt, grease, coatings, etc. by spraying dry ice pellets (particles) at high speed to the surface to be cleaned. Dry ice blasting machine is used in many industries due to its unique cleaning method and multiple advantages. The following are the advantages of dry ice cleaner:
