Plastic Cup Filling System

A dairy has a requirement to fill "Iced Coffee" at its current location. The environment is highly challenging because the humidity and warm climate create the perfect breeding ground for germs. To be able to fill here hygienically, the filling machine requires a sealed enclosure capable of isolating the outside climate. Despite these requirements, the factory space is limited, so the dairy requires a compact solution. 
 
Waldner has therefore developed a very compact filling line providing optimal sterilisation, enclosed in a clean air cabin with laminar air flow. The system also includes a checkweigher and a packing station.

The complete line comes from Waldner. For the customer, this means one point of contact and standardised operating elements - employees only have to familiarise themselves with one system. The clean air cabin surrounding the machine, in which there is a slight overpressure of clean air, ensures that the cups and lids are sterile.

Additional hygiene measures are also built into this machine: The cups themselves are disinfected on the inside with hydrogen peroxide (H2O2), while the aluminium cup lids are disinfected with ultraviolet light with a wavelength of 100-280 nm (UV-C).

Hydrogen peroxide is used to safely sterilise various cup materials, including cardboard cups, which are becoming increasingly more common for ecological reasons. This means optimum flexibility for the cup materials and maximum latte shelf life (at least 40 days).

The weight of the individual cups is checked by a checkweigher integrated into the outfeed conveyor. The weight information is immediately reported back to the filling system and automatically adjusts the filling volume in the event of any deviations. The system can quickly adapt to other cup sizes, materials, and recipes via an operating panel.
