Liquids are primarily handled in the beverage industry. Here, containers often have to be emptied of their residues before disposal. Only then can these be collected and pressed. To ensure an effective and efficient workflow, Strautmann has developed the LiquiDrainer dewatering system. This not only removes unwanted liquids from PET bottles, Tetra Paks and cans, but also seamlessly conveys the collected material into a baler.

Where to put unwanted liquids?

However, the dewaterer is not only suitable for residual emptying: It shows its full capabilities especially with full containers. This is a real advantage, because it is not uncommon that entire batches cannot be sold and have to be disposed of. For example, if the expiration date of the liquid has expired, the containers have been incorrectly labeled, or the product is not sufficiently popular with the customer. Residual samples must also be sent for disposal after a certain storage period.

Fast, safe and effective residual emptying

Whereas previously the containers had to be opened and the liquids poured out in a time-consuming process by hand, the machine does this completely automatically. All that is required is to place the filled containers in the feed chute. From there, they pass into a rotor that pokes holes in the outer skin to allow the liquids to drain out. These are stored in the collection tray and then discharged in a targeted manner. It doesn’t matter what type of beverage it is: Cans, PET bottles and the like are completely emptied and can then be easily processed further.

The advantages are obvious.

The combination of dewaterer and baler not only has a positive effect on the workflow, but also brings economic benefits. For example, the filled containers no longer have to be given to an external service provider who empties the liquids, nor do extra personnel have to be assigned for this purpose. This saves costs. Additional revenue is generated by selling the recyclables compacted into bales.
