Dry ice cleaning—The clean-in-place solution
The unique characteristics of dry ice make it the perfect media for a clean-in-place process.
Dry ice cleaning is an innovative cleaning technology that can save both time and money in the processing and packaging industry. Equipment and facilities get dirty with ink, glue, grease, wax, plastic/rubber molding process residues, carbon residue, proteins, seasonings, crumbs and other buildup, which prevents equipment from operating at peak efficiency and can shorten asset life. Traditional cleaning methods can be time-consuming, ineffective, involve significant amounts of chemicals or water – with the resulting residues and secondary waste – or rely on harmful abrasives that cause damage and shorten the asset life of the equipment.
Using non-abrasive particles of dry ice, accelerated with compressed air, effectively replaces traditional cleaning methods with a superior process. As the dry ice particles sublimate on impact, there is no secondary waste created, and equipment can be cleaned dry and in place without time-consuming disassembly. Additionally, dry ice is food-grade quality and can reduce contamination on surfaces of bacteria such as Salmonella, E. coli and Listeria. It can also reduce cross-contamination caused by nuts and other allergens, and remove protein residues on processing and packaging equipment.
Dry ice cleaning is fast, non-conductive, non-toxic and environmentally responsible. It is a soft media and non-abrasive on many surfaces, so it can be used to effectively clean delicate components and equipment without damage. Because it is a dry clean, it can be used around electronics and other sensitive components where cleaning with water or other solvents would normally be problematic.
That’s because the unique characteristics of dry ice make it the perfect media for a clean-in-place process.
No secondary waste
Cleaning with dry ice enhances sustainability efforts. It sublimates (turns from solid to gas) upon impact with the surface being cleaned, which means no secondary waste, no residue and no moisture being generated. This eliminates added costs of extra cleanup, disposing of secondary waste streams and additional cleaning preparation, such as masking delicate sensors or wrapping electronic components prior to cleaning.
The cleaning process does not use water, which allows equipment to be cleaned while online and still operating. Because it is non-conductive, dry ice cleaning allows for electrical equipment to be safely cleaned.
Dry ice is a very soft media and can clean sensitive electronic equipment, such as printed circuit boards, without etching, profiling or changing surface dimensions.
Dry ice is a food-grade media and is EPA-, FDA- and USDA-approved for use around food manufacturing. It is colorless, tasteless, odorless and non-toxic. It allows for the elimination of environmentally harmful cleaning chemicals and eliminates worker exposure to hazardous cleaning agents. It also does not produce any toxic waste that must be disposed of.
