NOVELTY - The charging equipment for the digestion or fermentation plant (13) includes modular functional components (6.1, 6.2) to achieve two distinct purposes at least. The first is a screw-, scraper-, or reciprocating conveyor. The other includes at least two roller components. Their axes of rotation share a plane including an angle of 45degrees - 90degrees with the conveying direction (F). The vessel chamber (3) includes a container (2) holding the feedstock (11) and a functional component (6.1) turned about a vertical axis (R) by a motor (5). There is a conveying system (10) below the container.    USE - Charging equipment for processing, conveying, buffering and dosing of biogas digester plant feedstock.    ADVANTAGE - This plant fulfills the charging objectives simply, rapidly and flexibly. Feedstocks of differing states and type are processed and conveyed. Modular construction assures that differing functional components can be applied to processing of different materials.    DETAILED DESCRIPTION - The functional components are constructed as comminution-, screening-, mixing-, dosing-, conveying-, or cutting modules. The vessel is divided into two chambers (3.1, 3.2) by a partition (4), each containing a functional unit. In a variation, a third modular functional unit is mounted in a passage through the partition. Further design details and variants are described, based on the foregoing principles. Salient features include a third modular functional unit mounted in a passage through the partition, and an arrangement of parallel conveyors to form a mixing path (M). A heater is included for sterilization of the feedstock. The container has a pivoted cover and a suction unit to remove emissions. It forms part of a biogas- or recycling plant. Wall surfaces include projecting cutter-teeth and/or blades.
