The feeding of digesters plays a key role in the economic and efficient operation of a biogas plant.

A reliable and effective solid feeding system will ensure optimal introduction of biomass to the digester with increased gas yield, lower energy consumption and reduced wear on the agitators and pumps. To maximise plant performance, it is becoming increasingly important to choose a feeding technique that can also process more difficult to handle materials.

With our Vielfrass® portfolio, you have a wide range of feedstock options. The variety of the Vielfrass® family is unique on the market: basic units from 5 to 13 m³, discharge container of 20, 30 and 40 m³ allow a multitude of possible combinations up to a discharge capacity of 90 m3.
