Abstract: A multi-row dough-portioning apparatus has a chamber housing having a number of portioning chambers for predetermining a portioned quantity of dough. Measuring pistons can each be displaced in the portioning chambers along a displacement direction between a retracted, measuring position and a pushed-out, ejecting position. A rotation-prevention bar is installed in a releasable manner on a rear wall of the chamber housing and interacts with a circumferential recess in the measuring pistons in order to prevent rotation of the same. The chamber housing has a projecting section, which projects beyond the rear housing wall. The rotation-prevention bar is installed on the chamber housing such that, upon release, it can be removed from the chamber housing in a removal direction perpendicular to the displacement direction of the measuring pistons. This results in a dough-portioning apparatus which, even in the case of large-volume portioning chambers, is easy to maintain and clean.

Abstract: A once-through baking oven has a plurality of oven modules which together form a once-through baking space. A heat-exchange heating device for indirect heating of the once-through baking space has a heating medium outward-flow pipe arrangement, a heating medium return-flow pipe arrangement and at least one intermediate radiator pipe arrangement having a plurality of heat exchanger pipes The heating medium flows in two adjacent heat exchanger pipes in opposite flow directions to each other. In an alternative embodiment of the radiator pipe arrangement, it runs in a spiral or meander shape in such a way that the heating medium flows in two adjacent pipe sections in opposite flow directions to each other. This results in a once-through baking oven that can be operated efficiently and adapted to different throughput requirements.

Abstract: A dough dividing device has a housing. Arranged therein is a feed chamber, for feeding dough, and a delivery chamber, which is arranged downstream and in delivery communication with the feed chamber. A delivery piston is arranged in a displaceably driven manner inside the delivery chamber for delivering dough. A measuring chamber is arranged downstream of the delivery chamber. In an extended delivery position a face of the delivery piston is arranged in a passage chamber between the delivery chamber and the measuring chamber. The passage chamber is delimited by a wall which extends circumferentially around the piston face. At least one degassing channel serves for degassing the measuring chamber. In the delivery position of the delivery piston the degassing channel is arranged between the piston face and the passage-chamber wall and creates a gas connection between the measuring chamber and a surrounding area.
