PlurryMaxx

Patented PlurryMaxx; The wet-disintegrato      

  

The patented PlurryMaxx Wet-disinterator can be tested in two months prior to any purchase (Scandinavian countries) - please inquire about conditions.      
  
                              

Well chewed is already half digested

The magnification of the substrate surface is advantageous for improved fermentation. A mechanical comminution is one of the most efficient disintegration techniques. PlurryMaxx is a device for comminution after the first anaerobic stage.

At high cutting speeds, the substrate to be fermented is ideally prepared for the microorganisms.

Thus, the extent of degradation and the plant efficiency is increased. The installation takes place inline in-flow so that - compared to a batch operation - no additional technical and time efforts must be applied.

The advantageous technical design of the PlurryMaxx also reduces the energy required for homogenization inside the fermenter. The low specific energy consumption results in a higher plant life. An installation for existing systems is easily possible, which in turn can lead to an increase in overall plant efficiency.

Ø  longer service life

Ø  better viscosities in the digester

Ø  lower agitation power

Ø  higher gas yield

Ø  possible use of alternative substrates

Longer service life without counter blades

The fermentation substrate is pumped through the cutting cylinder and thereby ground in the free section of rapidly rotating knives without being cut by counter blades.

By repeatedly cutting on several levels, the material is finely chopped. Due to
the high blade
speed, the substrate with its inertial mass acts as a counter blade. Thus, the maintenance intervals can be extended and a free passage is guaranteed at all times. This means reliability without

system failure. Even in the event of a fault, the bacteria feed is ensured in the fermenter.
The
plant availability is not dependent on a single component. The PlurryMaxx ensures safe operation of the plant with improved conditions for the microorganisms.

 

6 good reasons for the PlurryMaxx

Ø  good “digesting” to superfine particles                     

Ø  no counter blades

Ø  free passage, no substrate

Ø  congestion

Ø  ceramic inner coating

Ø  compact design

Ø  little effort — high efficiency

 

 

Cavitation - The power to break down cells

The aim of any disintegration unit is to break down the cells of the substrate to release organic

material. This additional available degradable organic material theoretically provides a bigger

yield of biogas. In combination with modern fermenter technology (fixed bed fermenter with

biomass recirculation), this potential yield can be exploited economically.

 

The rotating knife shaft causes a periodic compression and expansion in the medium. It causes

little microscopic voids in the cutting chamber.

The cavitation bubbles increase in size until they abruptly fall under the influence
of the surrounding pressure (implosion). Inside the gas bubble it can locally lead
to very high temperatures and pressures (> 1.000°C, > 100 bar).

The voids are produced on suspended particles and on interfaces in the cutting chamber. The interior of the cutting chamber therefore is fully treated with a ceramic coating.

The energy required for the PlurryMaxx is more than compensated by savings in stirring energy, the additional yield of biogas depends on the

substrate composition. Amortisation is possible within a short timeframe.

Additional yield through cavitation

Ø  release of organic matter

Ø  higher biogas potential

Ø  availability for microorganisms

Ø  lower internal shear forces reduce

Ø  demand of stirring energy 

 

Possible instalation situations of PlurryMaxx of a Biogas plant

Suitable for every anaerobic digestion plant 

 

 

Ranges of application - It depends on the correct position

 

Mechanical comminution may have different effects on the treatment of a substrate fermention

plant. Depending on the target, there are various application areas, although both the total

flow and partial streams are treated


The following objectives are feasible:

Ø  reduction of generation of floating layer

Ø  improved degree of organic degradation (bigger biogas yields)

Ø  optimization of the digestion

Ø  optimization of the denitrification (at wastewater treatment plants)

Ø  improved drainage behavior of the digestate for further following treatment

 

By using PlurryMaxx, the residence time can be reduced while increasing the degree of degradation and thus the biogas production.

 

Reduced susceptibility

Ø  no counter cutting

Ø  less floating layer inclination

Ø  increased digestion

Ø  full flow and partial flow treatable 

The energy consumption per tonne of silage of different crushing techniques and presentation Real results in the consumption of PluryMaxx during use

 

 

Technical data - High performance in a small space

 

Use of substrate diversity

More possibilities with greater flexibility By comminution alternative substrates are used

which previously were of limited use. So far, in the mixture fibrous substrates have been of limited use, as a physical limit is reached quickly due to the fast floating layer formation and the increased stirring.

With use of the PlurryMaxx, the substrate diversity can significantly be increased. The substrate efficiency is significantly improved by the use of more solid dung, whole plant silage or straw.

 

With PlurryMaxx enormous reserves of agricultural waste can be used in addition.

Municipal sewage
PlurryMaxx Wet-disintegrator is not only for use in Biogas plants, but also for use in a municipal sewage plant to reduce the volume of sewage slugde. Can here make a significant contribution to energy efficiency. Again, also here could the PlurryMaxx Wet-disintegrator be an effective contribution. 

The anaerobic digestion process is a proven technique for effective sewage sludge treatment. However, during anaerobic treatment, as a rule only about 50% of the organic matter in sludge is readily susceptible to biodegradation into biogas, the other half of the organic material being more recalcitrant and degrading very slowly. The combination of anaerobic sludge digestion and disintegration is seen as one promising technical method of enhancing the stabilization process.

Hence, a substantially increased degree of sludge stabilization can be achieved. Basically, the disintegration process is accomplished by the application of Wet-disintegration to break down cell walls. Thus, cell walls are fragmented and intracellular compounds are released.

The product can be utilized as a substrate in the anaerobic biological process.

Efficiency through straw pellets and PlurryMaxx
The opportunity in being able to get straw pellets pressed directly on the field to increase the biogas production, save workflows, more efficient transport, reduced storage capacity, automate the feeding of straw pellets into the biogas reactor - labor-saving process. The straw pellets as you can see on the attached Dias must be crushed by passing the pellets through PlurryMaxx Wet-Disintegrator, whereby the lignin cells will be opened so that the sugar herein can be available for the bacteria - thereby increasing biogas yield.

Company Buschmann produces the majority of PlurryMaxx Wet-disintegrator. The firm Buschmann was started in 1868 - it is an old well-established industrial company where the quality is enthroned. See their catalog here.
