Borger introduces new Powerfeed DUO

Borger, with US headquarters in Chanhassen, Minnesota, released its new fully automated Powerfeed DUO that is designed to have solids feeding and mixing technology with 15 cubic meters of storage capacity.

The Powerfeed DUO benefits from feed rates of up to 9 tons per hour and storage allowing up to 11 tons of feed—from just one load. Feedstock is mixed by a large mixing drum and then fed to a circulation line through a dry compression zone reducing oxygen input.
The stainless steel Powerfeed DUO can be loaded constantly by walking floor or periodically loaded with a dumper or a combination of both.

Connectivity is via Profibus and Ethernet as master or slave, which allows integration into any system.  Combined with a high-capacity Borger biogas pump, the efficiency of the Powerfeed DUO in breaking down solid particles in turn reduces the amount of agitation required in the digester, the company says.

The Powerfeed DUO’s auger shaft conveys the raw material to the press channel, compressing the biomass which is fed into the digester’s liquid flow via an induction unit from the organic plug in the system’s press channel.

An electronic display provides information about the weight of the biomass, allowing the exact dosage to be fed in. Sensors constantly monitor the fill level in the Powerfeed DUO, which will switch off automatically if pre-set limits are exceeded.
