BIO-MIX

Large wing mixer Fankhauser

Application fields

This agitator was developed especially for use in hydrolysis tanks, fermenters and secondary fermenters.

Mode of operation

The arrangement of stirring rod and stirring wings will cause a circular flow of manure and a thorough mixing in horizontal and vertical direction. By means of four stirring blades with a diameter of 2.30 meters a very efficient intermixture of floating and sinking layers can be achieved.
When feeding the fermenter with co-substrates the large wing mixer is operated with a nominal speed of 25 RPM. Afterwards the speed is reduced to 10% of rated capacity by means of a frequency converter so that the biomass is kept flowing slightly.

Gas evolution will be pushed and more biogas is produced in less time. The retention time of biomass in the fermenter therefore becomes shorter.
