High humidity and high temperatures aren't only found in tropical and subtropical climate zones, such as Southeast Asia. These extreme conditions are also often encountered in many production environments such as those in the Beverage, Food and Packaging sectors. LEIBINGER has developed an outstanding ink portfolio that can easily deal with these challenging production environments. However, there are applications and production processes where the ambient conditions impact on the inks’ processing and adhesion properties. Examples of this include food that is pre-cooked and filled during production, or printing cables in areas with high humidity and temperatures. Together with its customers, LEIBINGER has taken a closer look at these challenges and developed a solution to ensure maximum coding & marking efficiency and reliability.
The air dryer effectively counteracts humidity
Continuous inkjet printers (CIJ) use a continuous ink jet to print best-before dates, texts, codes or other markings. Conventional printers can cause condensation on the print head if the humidity is very high. Humidity can also affect both the inks’ viscosity and drying time. A solution developed by LEIBINGER with an integrated air dryer prevents this from happening and guarantees the inks’ adhesion and rapid drying – along with seamless, smooth operation.
This is how the air dryer works
In short, the LEIBINGER air dryer draws in the humid ambient air, removes the moisture from it and directs the resulting dry air into the print head. This ensures a dry environment in the print head, in contrast to the surrounding production environment.
