Weigher with rotating bins for filling of small bunches suitable for different products. The weighing unit consists of two bowl-like containers joined on their bottoms. Bulk material is filled into the container open on top with a dosing system. After reaching the target weight dosing stops and the container is turned by 180°. Now the other container has its opening on top and can be filled. Due to the rotation of the hoppers the emptying is very quick and the filling can start as the empty bin is turned on top.
