The Powerfeed twin feeds large quantities of varying biomass in
an enclosed system, safely and without odors, into your biogas
plant. The liquid feeding technology is equipped with an integrated
macerating unit and thus ensures a higher energy availability of the
biomass and, at the same time, less agitating required in the tank.
TWO FUNCTIONS IN ONE DEVICE
The Powerfeed twin technology was developed to be able to feed any kind of biomass.
Moreover, in the Powerfeed the biomass is pre-shredded and defibered in a compressed
state. The benefits are obvious. Not only the acquisition, installation and integration costs
but also the current energy costs of a separate macerator are eliminated. In addition to
that, integrating a macerating function into the feeding technology makes daily operation
a lot easier.
The biomass introduced is collected by augers (1) and fed to the compactor unit (2). The screw spindle unit
(2) which seals in every position conveys the biomass into the press channel (3). A replaceable narrowing is
attached to the outlet side of the press channel. Combined with the screw spindle unit, strong compression is
achieved in the press channel. The forming plug serves as a seal and offers additional protection.
The structure of the biomass is changed by the friction generated by the pressing procedure and trapped air
is released. Material disintegration can be increased if the optional macerating tools (4) are screwed onto the
rotating shafts. The press channel leads to the induction unit (5) where rotating blades scrape solid particles
from the plug. The solid particles are fed into the recirculate by means of rotating agitator blades. The release
of trapped air, the small size of the solid particles and the careful dosing into the recirculate ensure that hardly
any floating layers are formed in the fermenter. The agitating effort is significantly reduced and the power
consumption decreases. In addition, the large surfaces of the solid particles ensure a higher gas yield.
