Our feeding system

The sprinkling system provides the basis for a very simple solids feeding via the screw-press feeder. In the digester, hydrolysis and acidification zones are created at the entry point; a very advantageous storage area of fresh biomass inside the digester. This enables very flexible feeding intervals of up to 3 days. From this storage area, dissolved substances (organic acids) are distributed by sprinkling throughout the digester. This means that a large and complex bunker and feeding technology is not necessary.

Screw press feeder (STS)

As feeding system we offer our self-developed stuffing screw-press feeder in different dimensions. Our premise is to feed once a day directly into the digester. As fast as you bring the solids with the wheel loader, the screw transports them into the digester, a storage bunker is not necessary. This stuffing screw-press can cope with nearly all input materials without previous milling or processing.


An advantageous feature of the stuffing screw-press is the mashing of the feed, where fermentation substrate or fresh slurry is pumped into the stuffing screw-press and intensively mixed with the solids by the screw. This ensures that the solids already enter the digester in the form of a slurry. This very efficient feeding system is, as would be expected, made of stainless steel.
