Model DSP 205 -Screw Press
The Doppstadt Screw Press 205 is designed for solid-liquid separation of organic waste. During this process the bio-available fraction of the input material is concentrated in the liquid phase (filtrate). The filtrate is then used as a substrate to produce biogas using wet fermentation. According to the application the retentate can be composted or directly used as RDF. Usually the filtrate is pumpable and can be diluted by adding process water if necessary. The throughput depends mainly on the input material, the feeding and further factors. It averages between 7 and 12 t/h with a maximum of up to 20 t/h.
The main range of application of the DSP 205 is the processing of organic residues for a subsequent wet fermentation. The bioavailable fraction of the feed can be found in the liquid phase and thereby separate from packaging and contaminants. Digestate from dry fermentation plants can also be dewatered by the DSP 205 and transformed into stackable material. Material to wet for composting can be dewatered by the DSP 205 in order to ensure sufficient ventilation.
- no pre-shredding or pre-screening
- very low plastic contamination of the filtrate due to disintegration of packages via shear stress
- insensitivity to foreign bodies with a diameter of up to 80 mm
- low energy consumption due to co-rotating pressing cone
- easy maintenance due to bolted wear segments
