Dry ice blasting is known by several names: dry ice blasting, dry ice cleaning, CO2 blasting, dry ice dusting, and even environmentally sustainable cleaning. Dry ice blasting is an efficient and cost-effective way for industries to maximize production capability and quality. Dry ice blasting is similar to sand blasting, plastic bead blasting or soda blasting where media is accelerated in a pressurized air stream to impact a surface to be cleaned or prepared. But that's where the similarity ends. Instead of using hard abrasive media to grind on a surface (and damage it), dry ice blasting uses soft dry ice, accelerated at supersonic speeds, and creates mini-explosions on the surface to lift the undesirable item off the underlying substrate. Dry ice for blasting is manufactured in a form similar to rice, approximately 1/8" in diameter. Dry ice rice is generally used in dry ice blasting; an effective way to clean and decontaminate food processing equipment, metal and wood.
WHY DRY ICE BLASTING?
is a non-abrasive, nonflammable and nonconductive cleaning method
is environmentally responsible and contains no secondary contaminants such as solvents or grit media
is clean and approved for use in the food industry
allows most items to be cleaned in place without time-consuming disassembly
can be used without damaging active electrical or mechanical parts or creating fire hazards
can be used to remove production residue, release agents, contaminants, paints, oils and biofilms
can be as gentle as dusting smoke damage from books or as aggressive as removing weld slag from tooling
can be used for many general cleaning applications
How Dry Ice Blasting Works
We use compressed air from 185 cfm - 375 cfm at working pressures up to 200 psi to operate our dry ice blasting machines. Dry ice for blasting is pelletized CO2 the size of rice. After being loaded into the dry ice blaster it is forced through a nozzle, a process similar to media blasting, The ice sublimates on impact (going from a solid to a vapour with no liquid stage) Dry ice is a time sensitive product. Sublimation begins to occur at the time of manufacture, and it depletes at a rate of 1% per hour. It’s a good idea to pick up your dry ice as close to the time needed as possible and transport it in insulated containers to slow down the sublimation rate.
