Dry Ice Blasting for Paper Mill Equipment

A few weeks ago, several of our employees worked on a dry ice blasting project at a paper mill in New England. This paper mill specializes in filtration products, engineered papers and industrial non-wovens. Employees of this particular paper mill needed to clean several of their paper and filter manufacturing machines. One of these particular machines was a large drier with nine massive rollers. Rather than clean these machines by hand as done in the past, the Cryogenic Institute of New England, Inc. was chosen to clean the machines using its Nitrofreeze® Dry Ice Blasting Service. The plan was to clean three machines in a total of five days. One of these days includes a Saturday due to the New Year’s holiday.

I had the opportunity to go to the paper mill. The first day I went was to help get the equipment there, unload the truck, set-up our dry ice blasting equipment and start blasting the large drier. The first three steps went very smoothly and we started blasting at about 10:15AM. We decided to dry ice blast the two rollers at each end first before blasting the rollers above and in the middle of the machine. Each roller had a different degree of buildup that needed to be removed. In order to clean the rollers properly, we had to keep jogging the entire machine. Overall, it was a complex process, but the results were apparent. The rollers cleaned up very well and in far less time than it would take to do them by hand. Below is a picture of Robin dry ice blasting the roller. You can see the areas that have been cleaned on the roller.



Paper mill equipment is a good application for dry ice blasting. Rather than cleaning by hand with cleansers; dry ice blasting offers a safe, environmentally-friendly and faster way to clean. More surface area can be cleaned in a faster amount of time, reducing machine downtime. Dry ice blast cleaning also takes off contaminants without all the scrubbing which is labor intensive. If you are trying to reduce machine downtime while cleaning and want to be “green”, then dry ice blasting is a great way to clean. Below is a picture of a roller being dry ice blast cleaned. In the picture you can see the dry ice subliminating upon impact. This makes for less cleanup when compared to sand blasting, soda blasting and pressure washing.

Dry Ice Blasting Industrial Equipment


Dry Ice Blast Cleaning also known as dry ice blasting and co2 blasting has been one of our service offerings for the past two years. We have completed many jobs involving industrial equipment, fire damage, and mold remediation. Dry ice blasting is a very different yet environmentally friendly cleaning process.

Unlike sand blasting and pressure washing, dry ice blasting is approved by the FDA, EPA, and USDA. Why does that matter some may ask? The answer is simple, it allows us to clean food processing lines and equipment along with other medical applications.

Sand blasting leaves sand and grit all over the area to be cleaned; pressure washing leaves a slippery wet mess on the floor. These two cleaning processes cannot be used on every application for the cited reasons. Dry ice blasting doesn't leave anything on the floor except the grit from the surface that was cleaned. The dry ice (aka co2) that we use comes in pellet form. This means that it is about the size of a tic-tac. As the operator uses the dry ice blasting equipment, dry ice is blasted at the surface and evaporates as it cleans the surface. Therefore, there is no wet mess on the floor.

The most important principle that differentiates dry ice blasting from sand blasting and pressure washing is the fact that dry ice blasting is non-abrasive. Picture a brick wall that was painted white. Sand blasting it would take off the paint, destroy some of the grout, and damage the surface finish to the bricks. Pressure washing may take off some of the paint, but probably not all and don't forget the gallons of water all over the floor. Dry ice blasting will remove the paint, but keep the grout and surface finish to the bricks just the way it was before the bricks were painted.

Dry ice blasting can be used on different surfaces including metal, brick, wood, stone, and many others. The picture above shows our president helping us clean the Telegram & Gazette's main printing press located in Worcester, MA. Our company offers dry ice blasting throughout the whole New England area. For more information take a look here at http://www.nitrofreeze.com/dry_ice_blast_cleaning.html.
