How to dry a can ?


Yes, after the filling and seaming process, condensation is an issue when packaging cold carbonated beverages in aluminum cans. Problem is if the cans are packaged in cardboard boxes, the condensation can lead to the formation of mold or mildew, which can be a food safety concern. To mitigate this problem, there are a few steps that can be taken:

  1. Place the cans in a dry and  ventilated area before packaging them, this will slow down the mildew process.
  2. Use a warm air dryer to dry the cans before packaging them, this will remove any moisture on the outside of the cans.
  3. Use a tunnel warmer to increase the temperature of the can prior to drying it with blast of air. A tunnel have a large conveyor bringing slowly the cans through a series of hot water spray.
  4. Use powerful air blower around the can to remove any drop of water. Drops tends to run away from the blown air and stay on the can. So you better have great adjustable arms to bring the air on the right spots.

It’s important to note that this problem is not unique to aluminum cans, it could happen to any type of packaging that contains a cold beverage.
