Easyfeeder FA with push-off container - feeding the digester with renewable raw materials

The Easyfeeder FA solids feeding system with push-off container, type EBT-FA-AM, is designed for feeding the digester with renewable raw materials (RRM) such as grass and maize silage or similar biomass. But also more challenging materials such as all kinds of manure are processed without difficulty.
In the case of the EBT-FA-AM solids feeding system with push-off container, a loader fills the solid feedstock into the hopper. The ejector inside the storage container pushes the substrate into the rotary grinders of the shredder attachment. There, it passes through the rotary grinders to the main screw conveyor that feeds the separated material into the digester in doses.
Already during the development of the proved and tested feeding technology, the focus has been on minimising energy consumption and wear. Minimal operating times ensure minimum wear and low power consumption. In a 2009 study conducted by the Landesanstalt für Landwirtschaft (Bavarian State Research Centre for Agriculture) in Freising, in which 10 biogas plants were tested over a long period of time, our feeding technology proved to be a real energy saver compared to solids feeders from other manufacturers.
The EBT-FA-AM with push-off container has a simple and robust design. This makes the solids feeder particularly user-friendly and easy to maintain.
The system can be controlled directly at the unit via an optional stand-alone control cabinet or using the main control system of the biogas plant depending on the specific project. The user only has to program the pause and operating times. As an alternative to time-based control, the system can be controlled based on weight.
All drives are equipped with adjustable load monitoring. The interval control with automatic reversing function in the event of overload ensures smooth and trouble-free operation.

EBT-FA-AM - designed in line with the 2006/42/EC Machinery Directive

The EBT-FA-AM has been designed in line with the 2006/42/EC Machinery Directive and is conditionally approved for operation in potentially explosive atmospheres.

Structure of the Easyfeeder FA mit Mulde Typ EBT-FA-AM

The basic unit comprises a trough with digester connection that accommodates a swinging conveyor screw. The shredder attachment with three directly driven rotary grinders is mounted above the basic unit. The push-off container connects directly to the shredder attachment. The rotary grinders with their attached shredding hooks reliably break down even challenging substrates and provide for consistent feeding. A stainless-steel chute connects the basic unit with the shredder attachment. Components of the basic unit that come into contact with the conveyor screw are protected against abrasion by replaceable plastic inserts. The conveyor screws and planetary gears have a particularly sturdy and robust design. All parts prone to corrosion are made of V2A stainless steel by default.
