Easyfeeder Solo with push-off container type EBT-ST-AM - feeding the digester with renewable raw materials

The Easyfeeder Solo solids feeding system with push-off container, type EBT-ST-AM, is designed for feeding the digester with renewable raw materials (RRM) such as grass and maize silage or similar biomass. Partial amounts of more challenging materials such as all kinds of manure can also be added without difficulty.
In the case of the EBT-ST-AM solids feeding system, a loader fills the solid feedstock into the hopper. Inside the hopper, the separating screws break up and pre-dose the feedstock. The main screw conveyor efficiently transports the feedstock into the digester in large volumes.
The content of the push-off container is added as needed by activating the ejector unit of the push-off container and a hydraulic cylinder to the separating screws and the main screw conveyor. An ultrasonic sensor monitors the filling level in the EBT-ST-AM.
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.
Our feeding technology is characterised by a simple and sturdy 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. If fitted with scales (optional), weight-based control is also possible.
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-ST-AM - designed in line with the 2006/42/EC Machinery Directive

The EBT-ST-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 ECO EBT-ST-AM

As with all our components, challenging materials such as long-fibred grass or aggressive silage were used as a yardstick for the development of the EBT-ST-AM. As with all our components, we put the focus on ruggedness and durability. Therefore, the screw conveyor and the planetary gearbox have a particularly sturdy design.
Upon request, the parts of the push-off container that are prone to corrosion, such as the floor and the side walls, are made of V2A stainless steel. The interval control ensures uniform, automated feeding. Fitting the Vielfrass basic unit with a push-off container (with up to 50 m³ storage volume) saves valuable working time.

Control of the Easyfeeder ECO EBT-ST-AM

The interval control provides for uniform, automated feeding by time or weight based programming. The load monitoring function (load control) is an important element of the control system in this context.
