Andritz MeWa has further developed its cross-flow shredder for substrate treatment in biogas facilities, the Bio-QZ.
The machine is used in hundreds of European biogas facilities for processing different input materials, such as organic waste, corn silage, grass clippings and packaged food that has passed its sell-by date.
Flexible tools inside the machine produce a homogeneous substrate that leads to faster gas formation, shorter fermentation time and higher gas yield overall in the fermenter.
The development work focused mainly on easier maintenance. Besides a significant increase in the size of the maintenance port, access to the discharge, belt and belt pulleys has been simplified. In addition, the wear plates can be replaced more easily.
The new discharge geometry helps the material to pass through the machine smoothly without any blockages. The sealing system was also completely revised to give greater protection to the machine.
