Tietjen Verfahrenstechnik GmbH presents its press screw PRS for dewatering packaging material or sludge. This dewatering screw convinces with its robust design, which makes it one of the most maintenance-friendly and blockage-insensitive on the market.
In the application, the substrate is conveyed into the screw press PRS and compressed there: The material is compressed and pressed against the press flaps, adhering organics and liquids are discharged through screens. In the “FoodWaste application”, the organic material can then be used for biogas production, while the dewatered and compressed packaging material is cheaper to dispose of.
The PRS can be used separately or in combination with our DRM depackaging machine, which separates organics and packaging from packaged food waste. The packaging is then dewatered by the PRS.
