Dry ice-blasting is a form of carbon dioxide cleaning, where dry ice, the solid form of carbon dioxide, is accelerated in a pressurized air stream and directed at a surface in order to clean it. An alternative media for non-abrasive blasting is water-ice, known as ice blasting. The method is similar to other forms of abrasive blasting such as sand blasting, plastic bead blasting, or sodablasting substituted for dry ice as the blasting medium. Dry-ice blasting leaves no chemical residue as dry ice sublimates at room temperature.

2. Introduction to Dry Ice Blasting
 Alternative to conventional cleaning process used by food
companies
 Safe, cheap, efficient & ecofriendly process
 Uses recycled carbon dioxide (CO2)
 Capable of removing without chemicals or water fat-
based, protein-based, carbohydrate-based, and mineral
salt-based soils
 Approved by the Food and Drug Administration,
Environmental Protection Agency, and United States
Department of Agriculture

3. History
 Originated in the aerospace industry at Lockheed in
August 1977
 Technique became commercially available in 1987
 First patent regarding dry-ice technology was U.S. Patent
2,421,753 and were awarded to David Moore of Cold Jet,
LLC in 1986, 1988

4. Concept of Dry Ice
 Solid form of carbon dioxide (CO2)
 Colorless, tasteless and odorless gas found naturally in our
atmosphere
 Maintained at extremely cold temperature about -78.5 C/-
109 F

5. Technique Of Dry Ice Blasting
 Uses compressed air as kinetic energy to accelerate solid
carbon dioxide (CO2) dry ice pellets

6. Three Ways Dry Ice Blasting
Cleans

7. Uses In Different Sectors
 Mold Cleaning
 Baking and Food Processing
 Electrical Equipment
 Printing
 Aviation
 Foundry
 Automotive Parts Manufacturing and Assembly
 Equipment cleaning
 General Maintenance and Compliance Cleaning

9. Dry Ice Cleaning In Food
Processing Industries
The food industry faces the constant
challenge of maintaining cleanliness and
hygienic standards. Traditional cleaning
processes that rely on water and manual
scrubbing can be time consuming and
require strenuous labour. The innovative
process of dry ice blast cleaning is quickly
gaining widespread acceptance as an
alternative to conventional cleaning methods

10.  Solution for maintaining the cleanliness and hygienic
standards
 Completely dry process
 A recycled, natural substance i.e. solid CO2 pallets
making it extremely safe to use
 Eliminates the added cost and inconvenience of secondary
waste treatment and disposal

11. Blast Cleaning Optimization
 Achieving optimal dry ice blasting results
 Adjust the pellet speed and flow to suit the specific target
surface
 Factors to consider for optimization
The material type (ex: stainless steel, plastic)
The thickness and nature of contamination (ex: baked
on residues, hardened glue deposits)

12. Comparison
Traditional method Dry ice blasting method
 More equipment downtime
 Cleaner becomes hazardous
waste and as a secondary waste
 Poor quality of cleaning
 Potential Equipment Damage;
Grit abrasions
 Health threats from solvents
 Water-based cleaning pose
hazards around electrical
equipment
 Expensive process
 Less equipment downtime
 No additional contaminant
 Excellent quality of cleaning
 No equipment damage
 Standard safety precautions
 Dry process - safe around
electrical equipment
 Cost saving and cheap process

13. Food & Beverage Cleaning
• Dry ice blasting is an ideal process for cleaning containers,
mixers, conveyors and ovens
• A natural antibacterial cleaning method
• Beneficial in the carbonation in soft drinks
• Used to clean ovens, dry mixers and meat slicers etc.
• Cleaning done without cooling the oven or halting the
production

14. Typical Applications In The Food
Industry
 Production equipment - ex: oven, bake trays, slicers,
food mould, and fryers
 Packaging equipment - ex: folders, gluers, palletizers,
baggers
 Production environment - ex: walls, floors, piping,
exhaust fans
 Electrical components - ex: motors, switches, panels,
wiring
 Inaccessible or tightly spaced areas - ex: bulbous welds,
conveyor components, crevices, dead ends

16. Benefits Of Dry Ice Cleaning
 Waterless process
 Non-corrosive
 Deep cleaning
 Microorganism removal
 Costs savings
 Clean hot
 Non-hazardous

17. Eco-friendly Benefits
 Cleaning with a Natural Substance
 A Greener Clean
 A Thorough, Deeper Clean
 No Damage
 No Down Time

18. Safety Precautions
 Proper ventilation when working
 Hearing protection is required
 Protective clothing like gloves and face shields to stay
safe from the freezing temperatures

19. Conclusion
 Dramatically reduce equipment downtime, sanitation
labor, cleaning prep time, and costs associated with
replacing damaged equipment
 Helps to increase worker productivity and safety, both by
allocating labor more efficiently
 Product life is also greatly improved
 Support sustainability and green initiatives by eliminating
dependency on harmful chemicals and water
 Create a cleaner and safer production environment while
reducing costs and ensuring the safety and quality of food
products
