The Industrial Art of Cleaning

A production manager’s main concern includes keeping the food processing surfaces clean. A printing company’s major worries include keeping the printing press running, while architects figure out how to restore monuments and statutes.


Removing leftover food, grime, grease, mould, ink and other residue from production equipments is a critical task, especially when it comes to preventing bacteria growth and ensuring safety of the equipment.


As sanitation regulations have become more stringent, labor costs increase and the industries try to become more environmentally conscious, companies are now looking for newer cleaning solutions and processes.


Flour, grease, oil, ink along with bakes-on carbon (concerning food manufacturers) are some of the residues that are highly prevalent and very difficult and costly to remove from production equipments. So, to ensure product quality, residues need to be removed. Regrettably, traditional cleaning processes such as manual scrubbing, water and steam are not only slow and inefficient, but their ineffective as well.


Dry ice blasting in the food and foundry industry has provided some excellent benefits. That’s because some of the cleaning challenges including the cleaning methods of moulds, rubber, plastic, and ovens can be quite daunting.


Here are a couple of examples of the many cleaning challenges faced by companies:


  • Core machines and core boxes covered with sand, carbon buildup or binder.
  • Rubber and plastic vents and moulds that are caked in grease and mold release and residues.
  • Traditional methods of cleaning have included scrubbing and scraping and use of hazardous chemicals, which includes sandblasting.


The drawbacks of traditional cleaning methods are:


  • Labor intensive, which typically involves equipments being taken offline and cleaned.
  • Downtime – the extensive time required to effectively disassemble, clean up the molds and then reassemble them, resulting in costly production losses.
  • Grit entrapment which involves sand blasting and can become difficult to remove.
  • Mold Wear sand blasting can even wear down or etch surfaces.
  • Liability is another factor; the use of chemicals even poses safety hazards.
  • Cost of chemicals is expensive, plus they become an additional contaminated waste disposal cost.

So, with such major drawbacks, it’s quite understandable how companies have shifted towards Dry ice blasting and the preferred means of cleaning industrial equipments. Not only has dry ice blasting revolutionized the cleaning industry, but it has brought many benefits to many companies from various industries.

Looking Forward: Restoring after a Fire

In the aftermath of a house fire, many homeowners can anticipate a great deal of time and money will be spent on restoring the structure back to habitable conditions, even if the fire was very minor. Let’s take for example a lightning strike resulted in a chair that was positioned near an electrical outlet caught fire, resulting in a very small, yet very smoky fire. Although the fire may have been extinguished quickly and very little structural damage may have occurred, the entire house could still be filled with smoke, which permeates nearly every pore in the building. All the wood surfaces as well as the poured concrete walls and floors were covered with soot from the fire. After basement survey, it could be decided that dry ice blasting would be the best method to accomplish the cleaning task. Dry ice blasting provides fast and efficient removal of some and soot damage, without compromising on the surfaces integrity. Dry ice blasting also provides complete removal even in the tightest angles. Dry ice blasting provides complete removal even around nails, wiring and all plumbing areas. It’s much faster and cleaner than traditional cleaning methods. Dry ice blasting offers several advantages over the other cleaning methods. There are no hazardous chemicals involved, which instantly eliminates any danger to workers and the environment. Plus, it has a low disposal cost and cleaning is a minimal, limited to only material removal from the sooty surface. With an air compressor and dry ice blasting machines set in place along with blast hoses, the smoky wall can be cleaned instantly. The potential buildup of carbon dioxide which can occur when dry ice is pulverized after it hits the surface from being blasting at a high capacity, ventilation fans need to be installed to provide fresh air. Now the cleanup job using dry ice blasting uses pellets that are kept at a constant 115 degrees Fahrenheit. The pellets are fed into a hopper then the air compressor pushes the pellets out of along barrel onto the damage section. The force of the pellets is quite similar to sand blasting. As the pellets come into contact with the burnt area they begin to sublimate, turning from solid to gas and expanding about 800 times in volume acting like thousands of micro-explosion on the surface. This strips away the char while protecting the underlying substrate. Dry ice blasting is useful for a wide variety of cleaning projects. Whether you use it to clean up an industrial oven or remove oils from a large diesel genset, you can be sure you’ll get the job done effectively and efficiently with Dry ice blasting

Cleaning Tips for Food Manufacturers

The diversity of the food manufacturing industry and its applications can help demonstrate the diversity of how food manufacturers can use dry ice blasting technology for maintenance purposes. Food process and manufacturing facilities have many unique challenges when it comes to cleaning. Some areas that are difficult to clean and areas where water may cause bacterial growth or pose various other problems when it comes to electrical equipment, dry ice blasting cleaning can be used in these very areas quite successfully. The particles are made of food grade CO2, therefore nothing toxic is being introduced to the equipments substrates. In some cases, because of the extreme cold of the dry ice, -109 degrees Fahrenheit, dry ice blasting can actually remove a colony forming bacteria units and various other infectious growths that could hinder machinery performance. In cleaning on and around electrical equipment, this technology excels because it’s a dry process. There’s no liquid state in the blasting media, the CO2 pellets go from solid to a gaseous state on impact. This helps to ensure that no “wet” substance comes in contact with any electrical component during the cleaning process. This benefit, however, does seem very obvious. It reduces the probability of a wet motor or any other electrical equipment from getting wet and then being placed back into service only to cause major faults. This could cause major costly damage not only to the motor, but even to the production of products. Dry ice blasting process successfully removes baked-on residues in ovens and uncooked products that are left in the mixing equipment. It removes paper dusts from food packaging equipment and removes glue from glue heads. It’s used to clean waffle and cereal molds and because of the non-abrasive nature of the CO2 particles, it preserves the surface’s integrity. It works well on plastic and various other metal substrates; it even works on hot or cold surfaces. Plus, it’s safe to use around electrical equipment.
