Highly efficient digester mixers with unsurpassed efficiency Digester mixers

Pre-requisites for optimal reaction conditions graphic 1 Fast-running agitators tend to lead to the formation of „caverns“. This results in the substrate not being distributed throughout the entire fermenter which is known as „mixing in its own juices“. graphic 2 Slow-running large propeller agitators largely avoid the formation of „caverns“. The substrate is distributed through the entire fermenter. Anaerobic digesters are designed for average volume loads. This means that, irrespective of size, all parts of the fermenter must have a comparable load because reactor areas that are not...

Mixer efficiency! Reduce your internal power consumption! Currently, one of the greatest potentials for reducing internal power consumption is offered by optimising mixer technology. The decisive factor in the assessment of horizontal mixers is not the rated power of the drive unit but the power that is produced by the propeller with the aid of the drive in order to accelerate the medium forward in a horizontal direction. This power is called axial thrust. Mixers with a very good thrust/power ratio are characterised by large propellers. The propeller diameter is the decisive factor in the...
