NOVELTY - Fermenter system for the continuous fermentation of agricultural crops, preferably turnips or sugar beets, or intermediate products derived from agricultural crops, which are used as a starting material, comprises a storage depot for storing the starting material, a feed device for feeding of a fermenter (F) with the starting material from the storage depot, and an output bearing, into which residual material can be introduced from the fermenter by a connecting device. The storage depot and the output bearing are formed in the form of at least three storage containers.    USE - The fermenter system is useful for year-round and continuous production of industrially useful fermenter products, preferably biogas (B) (claimed).    ADVANTAGE - The fermenter system produces biogas continuously throughout the year, and reduces the space required and the cost for the storage of sugar beet.    DETAILED DESCRIPTION - Fermenter system for the continuous fermentation of agricultural crops, preferably turnips or sugar beets, or intermediate products derived from agricultural crops, which are used as a starting material, comprises a storage depot for storing the starting material, a feed device for feeding of a fermenter (F) with the starting material from the storage depot, and an output bearing, into which residual material can be introduced from the fermenter by a connecting device. The storage depot and the output bearing are formed in the form of at least three storage containers including a first, second and third storage containers, where the first storage container (L1) and second storage container (L2) are connected to at least one feeding device and the second and third storage containers (L3) are connected to the fermenter at least via the connecting device. An INDEPENDENT CLAIM is also included for continuous fermentation of agricultural crops, preferably turnips, sugar beet or intermediate products derived from agricultural crops, which are used as a starting material, comprising storing the starting material in a storage container for the successive feeding of fermenter, in which the starting material is converted into fermented residual material with the formation of fermentation products, which is transferred to a output bearing, storing the starting material in at least two separate storage containers including a first and a second storage container, where the loading of the fermenter with the starting material comprises feeding the fermenter with the starting material from the second storage container and the filling the third storage container with fermented residue material discharged from the fermenter to the second storage vessel, feeding the fermenter with starting material from the first storage container, filling the second storage container with fermented residual material emptied from the fermenter to the first storage container and filling the first and second storage container with starting material, and repeating the material flow steps.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic representation of the fermenter system.
