Hot Melt Adhesive Removal with Dry Ice Blasting
A typical line funnels beverage cans into 12 or 24 pack cardboard boxes (cases). Warm glue is applied onto the end flaps of each box. The end flaps are then pressed into position and sealed as the box continues along its course. The boxes are propelled along the conveyer rollers via a belt system. The drive belts are rather large, 12 to 14 inches (30.5cm to 35.5cm) wide by varying lengths (10 ft. (30m), 12 ft.(36m), etc.). In this packaging process, the warm glue often seeps out of the boxes and builds up on the drive belts. These drive belts are constructed from a composite of plastic and cloth material. Typically, the glue build up on the belts grows to an unacceptable level in two to three weeks. The current mode of operation is to dispose of the belts and install new ones. Cold Jet dry ice blasting can quickly and easily remove the glue build-up from the belts without damaging or wearing them. The expense of replacing the belts is gone as well as the down time required to install the new belts.

Conveyer Rollers Cleaned
Most packaging cardboard boxes are printed with a wax or clay based graphic. As these boxes are transported by conveyer rollers, the box coating is rubbed off the box and transferred to the rollers. The coating can then build up on the rollers to a level where boxes will begin to fall off the conveyor. The wax or clay build up is heaviest on the rollers making up the turn sections. Currently, the conveyor is dismantled every 4 to 10 days for cleaning by hand with solvents and brushes. The Cold Jet dry ice blasting process thoroughly cleans the wax or clay build up from the rollers while the conveyor is still assembled. Again, cleaning with dry ice blasting reduces the downtime needed for conveyor cleaning, thus increasing line productivity.

Ink-jet Code Overspray
All packaged beverage containers have an ink-jet code applied for information transfer and tracking. As with most ink-jet processes, an unwanted overspray occurs on nearby machinery, conveyers, belt drives, and electronics. Consequently, the ink will redeposit onto the package and create an unacceptable finished product. The Cold Jet dry ice blasting process gently removes the ink overspray and therefore prevents scrap or line shut-down.
