Pre-mixing system for heightened efficiency

 

 

The new MT-Mixator optimises the well-proven screw-based MT solids feeding system. This new system ensures regular and efficient biogas plant operation.

Recirculated material is flushed directly from the digester through a pipe into the stuffing screw of the solids feeding system. At the same time, non-pumpable substrates such as silage and solid manure are fed into the stuffing screw, which then acts as a mixing screw.

Solids and recirculated material are then already mixed when fed into the digester.

The advantages:

• Reduction of floating layers and heavy deposits.
• Lower mixing requirements in the digester mean less energy consumption.
• Less wear due to shorter stirring times.
• Positive biological effects on substrate decomposition.
• Regular gas production and homogenous gas composition.
• Recirculation from the secondary digester into the digester can be reduced.
• Lower sensitivity to extraneous material in comparison to other liquid feeding systems.
• Easily retrofitted to an existing MT-screw feeding system.
