The invention relates to a food-processing plant, in particular for the aseptic packaging of foods, which food-processing plant has a plurality of surrounded chambers, between which chambers a container conveyor is mounted. Said container conveyor has a plurality of container carrier elements, which have a flat surface and receptacles therein for containers such that the containers do not protrude beyond the flat surface at all or protrude beyond the flat surface less than 5 mm, preferably less than 3 mm. A container cover covers the flat surface during the conveying of a container carrier element from one chamber into the adjacent chamber.
