Application Cases
Food Processing Equipment Cleaning
Dry‑ice blasting machines are specialized cleaning equipment, and dry‑ice blasting technology has seen rapid global adoption. The system propels dry‑ice pellets onto target work surfaces with high‑pressure compressed air. Utilizing thermal‑difference physical effects, different materials separate owing to inconsistent shrinkage rates.
When −78 °C dry‑ice pellets strike fouled surfaces, thermal embrittlement‑and‑burst effects loosen contaminants. The pellets instantly sublime and expand 800‑fold, creating intense shear‑stripping force to remove fouling rapidly from substrate surfaces, delivering efficient, safe and energy‑saving cleaning performance.
CO₂ for dry‑ice blasting comes from industrial waste gas and high‑altitude air separation. The dry‑ice blasting process generates no additional carbon dioxide.
Automotive Dry‑Ice Blasting
Dry‑ice blasting is applicable to a wide range of scenarios, such as carbon deposit removal for automotive engines. This cleaning method causes no damage or disassembly to engines. Meanwhile, it represents an eco‑friendly cleaning solution, as no hazardous chemicals or environmental pollutants are generated throughout the blasting process.
Furthermore, dry‑ice blasting delivers improved cleaning efficiency. It enables multi‑component cleaning within a short timeframe, and the cleaning procedure is fully visualizable. Endoscopic inspection can be adopted to evaluate cleaning performance before and after treatment.
Electronic & Motor Cleaning
Dry‑ice blasting machines deliver high‑efficiency and eco‑friendly non‑destructive cleaning for electric motors with broad applicability. High‑pressure air propels dry‑ice pellets onto motor surfaces, causing contaminants to embrittle and detach rapidly for enhanced cleaning efficiency.
Requiring no chemical solvents, the process minimizes wastewater and waste‑liquid discharge for environmental protection. It achieves cleaning without inflicting damage to motors, extending service life and lowering maintenance costs. Featuring simple operation and easy maintenance, dry‑ice blasting machines constitute an ideal solution for electric‑motor cleaning applications.
Mold Cleaning
Dry‑ice blasting technology uses low‑temperature dry‑ice pellets to clean molds, delivering high‑speed, efficient and non‑destructive performance. It is applicable to molds of diverse materials, especially those with intricate hard‑to‑clean structures. Eco‑friendly and safe, this technology provides highly efficient, environmentally sustainable mold‑cleaning solutions for a wide range of industries.
Ship Dry‑Ice Cleaning
As vital means of transportation, ships rely heavily on proper cleaning and maintenance for their service life and operational performance. Conventional cleaning methods may cause damage to ship surfaces. In contrast, dry‑ice blasting technology has gained growing attention within the ship‑maintenance industry thanks to its high efficiency and non‑destructive characteristics. This paper discusses the application prospects of dry‑ice blasting technology in ship maintenance, as well as its great significance for ship cleaning and upkeep.
Aerospace Industry Cleaning
In the aerospace industry, dry‑ice blasting saves time while boosting equipment efficiency and service life. As a fast and safe method for maintaining various types of equipment, dry‑ice blasting performs a fully dry‑cleaning process that is safe for all electronic components on your equipment. It enables convenient on‑site cleaning without the need for machine cooling or disassembly. Being a non‑abrasive and non‑conductive cleaning method, it is completely safe for equipment and generates no hazardous waste.
