Doppstadt, with U.S. headquarters in Rockville, Maryland, introduces the BioPress DBP 205 screw extruder.
The extruder processes bags, shrink-wrapped items, and a variety of packaging including clear, paper, cardboard and foil. It is designed to be resistant to more than 3 inches of foreign bodies such as yard waste mixed with food waste.
The screw extruder runs on anti-fraction bearings and constantly presses materials through screening mesh. This separates liquid waste, which can be used for biogas, from solid waste, which can be used for composting. The screening mesh is available in different perforations.
The extruder is driven by a hydromotor with planetary gear that has load-sensing speed control for hydraulic drive.
