Dry Ice
The "Dry Ice Uniformity" is a key element in ensuring the performance of dry ice cleaning.
In practice, specific sizes and dry ice densities are required for different customer needs to avoid incomplete cleaning or damage; moreover, to ensure consistent particle size production for the best cleaning results.
In today's dry ice cleaning market, only our dry ice manufacturing machine can produce "continuously uniform-sized" dry ice pellets and blocks, with a production capacity of 1,000 kg per hour.
- FEATURE
Dry ice cleaning technology is a physical cleaning method that uses solid carbon dioxide (CO2), known as dry ice, to remove surface dirt, oil stains, or other contaminants. It is typically used for cleaning and degreasing purposes in various applications, including machinery, industrial equipment, and food production equipment.
The principle involves transforming solid carbon dioxide into small particles and propelling these dry ice particles onto the surface that needs cleaning using a high-speed airstream. When dry ice particles come into contact with the surface, they rapidly sublimate into a gas, releasing energy that pushes dirt and contaminants off the surface.
Dry ice is a solid gas, so it leaves no residual moisture or chemical substances during the cleaning process. Furthermore, it can clean hard-toreach areas without the need to dismantle equipment. Since the CO2 used is a byproduct of industrial processes, it does not produce carbon dioxide emissions, making it an environmentally friendly choice. Dry ice cleaning is suitable for various surface materials, such as metal, glass, rubber, or plastic.
- Before the dry ice cleaning process begins, solid carbon dioxide is compressed and cooled, converting it into small dry ice pellets.
- Dry ice particles are propelled onto the surface to be cleaned using a high-pressure airstream, coming into contact with dirt and contaminants.
- When dry ice particles make contact with the surface to be cleaned, they rapidly sublimate into gas, releasing energy. This energy transfer dislodges and fractures dirt and contaminants from the surface.
- Following the energy transfer from the dry ice particles, dirt and residual substances are swiftly removed, leaving the surface clean without any moisture or chemical residue.
- Throughout the cleaning process, we collect the used dry ice particles, ensuring safe disposal and recycling. This ensures that all dirt is completely removed.
- No Chemical Residue
Dry ice cleaning does not require the use of chemicals, leaving no chemical residues on cleaned surfaces. This makes it especially suitable for industries that demand a residue-free environment, such as the food and pharmaceutical sectors. - No Need for Moisture
Unlike many traditional cleaning methods, dry ice cleaning does not require the use of water because dry ice particles sublimate upon contact with surfaces. This reduces water resource waste and is particularly advantageous for applications where keeping surfaces dry is a crucial factor to prevent damage onto the equipment, machinery, or electronic components. - Reduced Downtime
Dry ice cleaning is typically fast and efficient, significantly reducing equipment downtime. This is significant element for the maintenance of industrial equipment and production lines, saving production costs and time. - Versatile Applications
Dry ice cleaning can be applied to a variety of surfaces, including metals, glass, rubber, plastic, and more. It is suitable for multiple industries, such as electronics, construction, and food manufacturing. - Environmentally Friendly
Dry ice cleaning is a relatively eco-friendly cleaning method as it uses CO2 extracted from industrial byproducts. Additionally, it does not produce pollution or harmful gas emissions. - Excellent Cleaning Results
Dry ice cleaning efficiently removes various types of dirt, oil stains, residues, and contaminants, leaving surfaces clean and smooth. - Non-Damaging to Surfaces
Due to the gentle nature of dry ice particles, it does not cause damage or abrasion to most surfaces. This is advantageous for protecting the appearance and integrity of equipment and components.
Carbon dioxide dry ice machines are commonly used in several fields, including:
- Semiconductor technology
- Food processing industry
- Automotive technology
- Processing of plastics, extrusion, and rubber molding
- Printing and electroplating

- Various paper processing techniques
- Manufacturing various metals
- Environmental pollution remediation and waste treatment cases.
| Traditional Cleaning | Dry Ice Cleaning | |
|---|---|---|
| Equipment Disassembly | Traditional cleaning often requires the disassembly, cooling, and reassembly of equipment for thorough cleaning. | Dry ice cleaning can reach areas that traditional cleaning cannot without the need for disassembly, and production can resume immediately after cleaning. It creates no secondary pollution as dry ice sublimates upon contact with surfaces. |
| Pollution Issues | Cleaning materials can generate secondary pollutants, such as wastewater produced during the cleaning process. | It creates no secondary pollution as dry ice sublimates upon contact with surfaces. |
| Cleaning Time | Traditional cleaning methods are timeconsuming and laborintensive, including equipment disassembly and reassembly. It is estimated to take 20 days. | It takes only 5 days, which is a quarter of the time required by traditional cleaning methods. |
| Cleaning Effect | Traditional cleaning struggles to effectively clean tightly packed inner heat exchanger tubes, resulting in fouling that decreases heat transfer efficiency over time. After a cleaning in 1997, the flue gas outlet temperature only decreased by 7°C, increasing highpressure steam production by 0.59 MT/HR. | Dry ice cleaning can effectively clean the gaps between finned tubes and tightly arranged inner heat exchanger tubes, leading to a 16°C reduction in flue gas outlet temperature (from 190°C to 174°C), increasing high-pressure steam production by 1.28 MT/HR. |
| Harm to Equipment | Traditional cleaning methods can cause wear and contamination in the cleaned area. | Dry ice cleaning is environmentally friendly and does not cause harm. |
| Safety | Traditional cleaning methods may pose environmental and health hazards and cannot be used in live or energized environments. | With standard safety precautions, it can be used in live or energized environments. |
