In the field of industrial cleaning, when dealing with stubborn wax residues on the inner walls and heating coils of dewaxing kettles, a highly efficient, non-destructive, and dry cleaning solution - dry ice blasting technology - is gradually replacing traditional labor-intensive manual cleaning methods with its outstanding performance, becoming the preferred choice for ensuring equipment safety and operational efficiency.
The Pain Points of Traditional Cleaning: Time-Consuming, Damaging, and Unsafe
As a core piece of equipment in the beekeeping, plant extraction, and chemical industries, the dewaxing kettle often accumulates wax and organic residues on its inner walls and heating coils. These stubborn contaminants not only severely reduce heat transfer efficiency-causing energy consumption to soar-but also lead to cross-contamination of products and corrosion of the equipment.
Traditional manual cleaning relies on tools such as iron scrapers and steel brushes, which involve high labor intensity and long cleaning cycles. More critically, hard scraping can seriously damage the smoothness or enamel coating of the inner surface. Once the protective layer is compromised, the kettle becomes more susceptible to corrosion, creating a vicious cycle that drastically shortens the equipment's lifespan. Meanwhile, the use of chemical solvents during cleaning can also pose environmental and safety risks.
Dry Ice Blasting: Principle and Advantages
Dry ice blasting technology perfectly addresses all of these challenges. It works by using compressed air to accelerate dry ice pellets (at -78.5°C) to supersonic speeds, which then impact the surface to be cleaned.
The dry ice pellets strike the contaminated surface, rapidly freezing, embrittling, and cracking the residue, causing it to detach from the substrate.
In milliseconds, the dry ice absorbs heat and sublimates into CO₂ gas, expanding nearly 800 times in volume. This "micro-explosion" thoroughly lifts and removes the cracked contaminants.
The entire process is purely physical and generates no secondary waste. The dry ice disappears completely after impact, leaving only the removed residue. Because it is non-abrasive, it causes no damage to metal, enamel, or mirror-polished surfaces.
Case Study: YJ-09 Industrial Dry Ice Cleaning Machine in Dewaxing Kettle Maintenance
For example, during a routine maintenance operation at a well-known domestic honey product processing enterprise, we witnessed the outstanding performance of the YJ-09 industrial dry ice cleaning machine.

2)Cleaning Target: A 1500-liter dewaxing kettle and dewaxing cart with wax buildup averaging 1–3 mm in thickness.
3)Cleaning Objectives: Inner wall, dome, bottom area, and complex heating coil assemblies of the kettle, as well as the surface of the dewaxing cart.
Cleaning Results and Efficiency
Dry ice consumption: It takes about 180 kg to thoroughly clean a dewaxing kettle and a dewaxing cart..
Cleaning duration: Approximately 120 minutes from preparation to completion - over 200% faster than the traditional manual cleaning process, which typically takes 4–5 hours.
Preparation time: Only 30 minutes for setup and adjustment. No chemical residues or rinse water remain afterward, allowing for "clean and ready-to-use" operation.
Visible and Invisible Improvements in Cleaning Results
1. Visible cleanliness
After cleaning, the kettle's inner wall was restored to its original metallic color. The wax buildup between the heating coil walls and fins was completely removed with no residue remaining.
2. Invisible performance enhancements
Quality assurance: Eliminated risks of cross-contamination caused by residues.
Energy efficiency: Post-cleaning, heat transfer efficiency of the coils was restored to near-new condition. According to the company's follow-up data, energy consumption per batch was reduced by about 15%.
Equipment protection: Professional inspection confirmed that the enamel coating inside the kettle remained fully intact with no new scratches or damage, ensuring long-term equipment durability.
