Drying PE film with a RUNI Screw Compactor and save energy

RUNI SK370 presses water out of the washed PE-film. This method is less energy intensive than the traditional drying with centrifuge and thermal heat.

During the production of recycled plastic from PE film, the cut-up film is washed thoroughly and then dried. Traditionally, the drying process is carried out using hot air, centrifuging and agglomerating.

However, a considerable amount of this energy-demanding  drying the PE-film process can be replaced by pressing the water out of the wet PE film using a RUNI screw compactor SK370.

The drying/compacting process increases the dry matter content of PE film from 60 % to 90 % at a low energy consumption of only 24 kW per 1.000 kg PE film.

When the screw compactor is installed right after the centrifuge the process will be faster and increase the capacity on the whole drying line. The investment will quickly be recouped.

The RUNI Screw Compactor SK370 has been developed to operate on a fully automatic production line, 24 hours a day, 7 days a week of approx. 800 kg per hour.

A de-compactor unit can be installed to loosen the PE-film after it has been compacted. This can be usefull if the PE-film should be blown to next step.
