Vario’s Mobile Slurry System
EVERY BIOGAS PLANT OPERATOR MUST HAVE ASKED HIM OR HERSELF THE FOLLOWING QUESTIONS:
- What are the alternatives, if the solid matter feeding system breaks down?
- Who is in a position to provide speedy assistance?
- How can I continue feeding during a cleaning operation?
- What advantages does a slurry system offer?
THERE IS NOW AN ANSWER TO THESE QUESTIONS:
Terbrack Maschinenbau’s mobile feeding system guarantees you fast, flexible assistance if your feeding technology malfunctions. This will allow you to minimise biological issues and gas yield losses.
To connect the mobile equipment, all you need is an electricity supply of 380/400 volts, secured by a 63 amp fuse. In addition, the digester must be equipped with supply and evacuation tubes of at least DN-150 size (standard liquid manure pipe). The machine will be ready to use after a set-up time of around 2 hours. The 16 m³ storage tank is mounted on load cells and can be loaded with up to 9 tonnes of maize silage. A frequency converter-controlled screw feeds the material into the slurry system, in accordance with pump capacity (flow meter). 
The machine can receive 8–10 tonnes of maize silage per hour. Pressure sensors and electrically controlled valves prevent uncontrolled spillage from the digester.

OPERATING REQUIREMENTS FOR THE MOBILE SOLID MATTER FEEDER
CONNECTIONS:
Electricity: 380/400 volts 3Ph N PE / protected by a 63 amp fuse (CEE plug 63A max. connected load 35 kW) 20 metres of cable are supplied with the equipment
2 connecting pipes with at least DN150 unobstructed passageway (standard liquid manure pipe), a 20 m pipe is supplied with the equipment)
2 connecting pipes with at least DN150 unobstructed passageway (standard liquid manure pipe), a 20 m pipe is supplied with the equipment)
INPUT MATERIALS:
- Maize silage: unlimited quantities, 30–40% DM (dry matter)
- finely chopped whole crop silage: up to 70% with 28–36% DM
- CCM (corn-cob-maize) cereal: up to 30%
- grass and manure: up to 70%, fibre length must not exceed 15 cm
OPERATING REQUIREMENTS:
- The DM content of the suctioned manure must not exceed 9%
- Gas bubbles must not be able to form at the extraction ports. If the extraction port through which the manure is suctioned is facing downwards in the digester, a gas bubble can form inside. This jeopardises the smooth, uninterrupted operation of the equipment.
- The suction pipe should be kept as short as possible
PERFORMANCE:
- Depending on local conditions, conveyance performance is around 8 to 10 tonnes of maize silage per hour
- Conveyance performance is influenced by:
- DM content
- The path / height of the conveyance system
