The facility consists of an unloading table equipped with a roller/reflector that distributes the chopped grass evenly and avoids the risk of clumping. The grass is then transported to a double-screw screw press, which compresses the grass under high pressure to produce a fiber-rich press cake and a protein-rich press juice. The press cake is further transported out of the facility via a conveyor belt. The pressed juice is collected in a smaller vessel and then pumped on to a larger buffer tank with agitation where it is kept chilled.
At the plant at Sötåsen, a silage has mainly been pressed, in order to be able to run the plant all year round. The fiber-rich press cake has been used within the project as feeding for dairy cows and heifers, while the protein-rich press juice has been used as a supplement for wet feeding for growing pigs and sows.
