The BACKHUS LTC Mix can be used for application within closed systems and integrated into any new system with a rotting tunnel. The Digestate Mixing Unit consists of a mobile unit, which moves back and forth on a suspended roof above the composting tunnel by means of a chain drive. The rotor of the unit protrudes through a narrow opening into the lower region of the tunnel and turns over the material in this area as it moves along.

Rotor and input material

The rotor has a diameter of 1.4 metres with an overall size of 4 metres and is suitable for mixing material up to 1.8 metres in depth. The maximum clearance from the floor is just 50 mm.

The starting stock consists of one part of digestate and one part of structural material (green waste). Using the BACKHUS LTC Mix, Digestate Mixing Unit, a homogeneous material is produced, with a corresponding air pore volume suitable for aeration, i.e. a biodegradable substrate.

Mixing digestates in a closed system

Using the unit loosens the material without compaction. To produce an ideal result from mixing, the material is turned with two successive passes. The first pass pre-mixes the material and breaks up any potential clumps. The second pass then adds significantly to refining the mixing result.

The Digestate Mixing Unit works in closed or covered systems, as an alternative to mixing outdoors. The emissions released in the covered system during the mixing process are captured and fed into an exhaust purification plant. This significantly reduces emissions to the outside, especially odour emissions.

The BACKHUS LTC Mix gives you all the advantages of a fully automated process. Control of the unit and all operations are regulated by a computerised system.
