Abstract: The dough portioning device comprises a funnel (2) for a dough mass (3) having a lower-side opening (4) for the discharge of dough mass for portioning, and two conveyors (7, 8) for the dough mass from the funnel arranged in the lower-side opening. The conveyors have end-areas (5, 6), whose position is changeable relative to each other in such a manner that it includes gap suitable in a first position, where a dough portion of the dough mass is separable through the gap in a second position. The position of the end areas of the conveyors is changeable by the displacement of a storage roller. The dough portioning device comprises a funnel (2) for a dough mass (3) having a lower-side opening (4) for the discharge of dough mass for portioning, and two conveyors (7, 8) for conveying the dough mass from the funnel arranged in the lower-side opening. The conveyors have end-areas (5, 6), whose position is changeable relative to each other in such a manner that it includes gap suitable in a first position, where a dough portion of the dough mass is separable through the gap in a second position. The position of the end areas of the conveyors is changeable by the displacement of a storage roller, by equally changing the position of the end areas of both conveyors and/or by a change of the position of the entire conveyors. The roller is adjustable while maintaining their distance to the end areas of the conveyors. The conveyors are independently, interdependently and/or variably controllable in a control unit and/or are formed for continuous operation in opposite direction with respect to a change of the position of the end areas. A device for adding flour is intended at both conveyors. A measurer edge and/or a roller are intended at the end areas. Flow characteristics of the dough mass are influenceable by the conveying movement of the conveyors and/or the position of the end areas of the conveyors is adaptable with respect to the desired flow characteristics of the dough mass. The position of the end areas is changeable with respect to a filling level of the funnel and/or with respect to the dough yield of the dough mass and/or a further dough characteristic. A balance chamber for receiving and weighing the dough mass from the nozzle, is arranged below the end areas. The dough portioning device further comprises a delivery belt and a control unit for controlling the weighing method and/or for comparing weights of the weighing method of the balance chamber, where the control unit has a target weight for the dough portion. The position of the end areas is changeable with respect to the reaching of the target weight through the dough mass and/or by the control unit. The weighing device comprises an outlet means for the delivery of the balanced dough portion on a further conveyor forming balance and/or a conveying belt. The well-balanced dough portions are connectable with one another on the balance and/or transition belt and/or on the delivery belt in dependence of a control of the control unit and/or for weighing a difference between a preset weight and an actual weight determined in the weighing equipment and/or for the production of an uniform dough mass flow. The conveyor forming the balance and/or transition belt and the conveyor forming the delivery belt are operated with different speeds with respect to the preset weight and actual weight. The conveyor forming the delivery belt consists of two side bands and a base band and/or comprises an oscillation plate and/or a roll gear for the production of a desired cross section of the dough volume. An independent claim is included for a method for dough portioning using the dough portioning device.
