In the pharmaceutical industry, it’s rather critical to ensure products are appropriately marked and labeled. This allows for proper tracing of the product throughout the manufacturing process and ensures the end customer has the necessary information they need on the container the products are packaged in.
For some processes in this industry, labeling applications present a few problems. While in many cases the problems are attributed to static electricity, I recently worked on an application for removing condensation prior to a labeling process. While this is a common application we help serve in the Food & Beverage Industry, this one was a first for me with regards to pharmaceuticals.
The manufacturer of a variety of different pharmaceutical products used for animals was having an issue with a few of their products they produce. They had a line that processes a variety of different styles of products, but with one particular type they were having this issue with the label application.
Some of their products must be held at relatively low temperatures. Throughout the filling process they are held within a refrigerated zone. The area in the facility where the labels are applied is also climate-controlled, but not completely refrigerated. The bottles are only in this location for the brief labeling process before being placed back into coolers, but it was not possible for them to relocate the labeling process elsewhere.
The issue they were having was occurring during the warmer, humid days of summer. As the bottles were placed into the labeling machine, condensation would form that prohibits the label from correctly adhering. This led to a lot of rework and manual label application, while also contributing to some waste as products were held outside of refrigeration for too long.
They began seeking out a solution for blowing off the residual condensation prior to labeling and contacted EXAIR for a solution. To combat this problem, we implemented a two-tiered blowoff solution. There was a rotating table where the product is initially held, (2) Model 110024SS-316 Stainless Steel Super Air Knives were used to provide an initial blowoff inside the contained area. This took care of some of that initial condensation, but left some bottles with still a bit of residual moisture that was still creating issues.
We added a Model 120020 ¾” Super Air Amplifier to blow on each individual bottle immediately prior to labeling to take care of any condensation that formed after the initial blowoff. With both of these solutions in place, the condensation is immediately stripped off the outside of the vials and allows for a clean label application each and every time.

EXAIR offers a wide range of products that can be used for blowoff. Options are available in 316 Stainless Steel from stock for a variety of applications in both the Food and Pharmaceutical Industries.
