ENSPAR offers robust and low-maintenance technology for the dosing of solid substrates, e.g. maize, GPS, grass silage, solid and poultry manure. The feed into the digester is carried out using proven screw technology below the liquid level.
Dosing units for solid substrates
A biogas plant can be fed evenly and reliably with a screw conveyer system in combination with a solid dosing unit. The substructure of the dosing unit is standardly manufactured of stainless steel. Optionally, the top element, the mixing screw and it´s knives can likewise be delivered in stainless steel. Low wear is thereby guaranteed.
The drive operates with robust geared motors with subsequent cardan shaft and planetary mitre gear. A shear pin clutch is integrated in the powertrain as safeguard. The consistency of the added material has a decisive influence on the duration of the mixing process. An optimal operation is guaranteed with chopped raw materials of 3-5 cm length. For longer materials, we recommend the use of cutters in the dosing units.
For the safe and reliable injection of solids into a flow-through, closed piping systems, ENSPAR's liquid NawaRo injection technology is a guarantor. We recommend this technique for plants with a high liquid share and fibrous materials.
This dosing technology is available for the injection of up to 5t / h or up to 9t / h. The Fastfeed 300 can handle up to 4 t / h at very low, wear-resistant speeds, while the Fastfeed 400 can deliver up to 9 t / h. The feeding power can be increased by increasing the rotational speed.
