EXAIR Super Air Knives Increase Production of Jar Labeling Process

When a customer has a problem with a labeling process within their operation, many times they call EXAIR to provide a solution. The company in this example manufactures honey and dispenses it into jars and squeeze bottles. Due to an increase in demand, they were looking to increase their output. To do this, they simply increased the speed of their conveyor to accommodate approximately 70 jars per minute instead of their typical 50 jars per minute. This began to present a problem and they reached out to EXAIR for a solution.

After dispensing the honey, the jars and bottles travel through a washing station. The containers pass through a heated chamber that dries the excess water from the jar. At the higher speed, they were experiencing some residual water left on the containers. This began to pose an issue when they reached the labeling process. With water remaining on the jars, the labels adhesive would not adhere properly. This led to an increased amount of rejections and additional rework time to remove the rest of the label and re-run the defective containers.

They had a point in the conveyor just prior to labeling that the sides of the jar would be exposed. My recommendation was to install (2) 110009 9” Super Air Knives on each side of the conveyor to remove the water that was left after exiting the drying chamber. This worked like a charm and the customer was able to maintain an increased level of output without experiencing any further complications. Their previous rate of production without the Super Air Knives was approximately 50 jars per minute.  By installing the Super Air Knives, they were able fully realize their 70 jars per minute goal and increase their production by 40%!

The laminar flow that exits the Super Air Knife wraps itself around the outside of the jar, stripping away any leftover moisture. Supplied at 80 PSIG, each knife will consume only 26.1 SCFM of compressed air at a sound level of just 69 dBA. The flow and force from the knife are infinitely adjustable by dialing in the operating pressure with a pressure regulator or swapping out the shims with a Super Air Knife Shim Set. If you’re experiencing an issue with residual water or liquid on your product that is causing a problem during production, give us a call.
