And yet another advantage of using straw
“There’s no way I can ever agitate 50% straw,” said a biogas plant operator from the Rottal who has a self-built biogas plant. “Nobody I know within 20 km can use maize straw, because they can’t agitate it. Let alone cereal straw.”
Of course you can’t simply replace 50% of your maize silage with straw. Nobody says that.
For years I searched for the optimal agitator for our batch hydrolysis. Again and again we made improvements. But I was never really satisfied.
An agitator must
⦁ easily handle 15% dry matter
⦁ also up to 20% dry matter if a floating layer should form
⦁ use little electricity
⦁ be robust and trouble-free
Our batch hydrolysis now has the agitator that meets these requirements.
High peak power with a 22 kW electric motor. It agitates everything.
Low power consumption in normal operation.
A service factor (ratio of electric motor to gearbox) of 2.7. Normal agitators have a service factor of 0.8. It still agitates after a power cut when a floating layer has formed.
Stainless steel double tube and therefore torsion-free.
Oh, what does it cost? Probably a fortune.
What costs you a fortune is having to dredge out your digester. That costs more than the whole agitator.
What does it bring? Peace of mind!
In addition, using straw can reduce the nutrients in your fertiliser balance. You can read more here .
