Doppstadt’s new mobile Screw Extruder for organic waste: BIOPRESS 205

Posted on October 27th, 2010

Doppstadt’s new BIOPRESS 205 s an ideal machine to separate the liquid and solid fractions from bio-degradable wastes. The mobile screw extruder is driven by a hydromotor. The rotating cone presses the material with a pre-set pressure through the screening baskets, which are available with different mesh sizes. The liquid fractions can be used for biogas production and the solid fractions for thermal utilization or for composting.

Powerful and flexible

A 500 mm (1′ 8”) screw diameter and 17 - 26 rpm (adjustable) ensure a high throughput. The BIOPRESS 205  processes food and supermarket wastes, biomass, rejects from the paper industry, etc.

 

  • A 500 mm (1′ 8”) screw diameter and 17 - 26 rpm (adjustable) ensure a high throughput.
  • Input materials, e.g. mixed biowaste can be pressed trough the screening baskets with different mesh sizes and are then discharged.
  • Applications: food and supermarket wastes, biomass, rejects from the paper industry …
  • maximum throughput and optimal dehydration of the materials to be pressed thanks to variable mesh sizes of the screening tunnel
  • easy to change screening baskets with different perforations to meet various demands
  • easy to change wear elements on the extruder
  • constant discharge of solid fraction thanks to peripheral pressing gap
  • hydraulically adjustable cone with pressure-dependent control
  • high wear resistance
  • up to 70% dehydration for organic wastes
  • driven by low-maintenance hydro-motor
  • load-sensing speed control for hydraulic drive (optimal torque)
