A plant (1), preferably a freezer tunnel for temporary storage of items, and comprising an inlet station (3) and a discharge station (2) and a conveyor (4) for carrying the items through the plant, may be provided with a buffer effect in a simple manner. The conveyor (4) loops around fixed turning rolls (9). The buffer storage is established in that a drive member (14) for the conveyor (4) is provided both at the inlet and the discharge station (2, 3). Any one of these two drive members is constructed to be operated at a speed that is different from the speed of the other drive member. Furthermore, the drive members at the discharge station may be reversed in order to move the conveyor in the discharge station back into the freezer tunnel. As the trolley (17) is in a freely displaceable position, a difference in speed will mean that the conveyor section (24) between the trolley (17) and the fixed turning rolls at one side of the plant may be enlarged and reduced. The conveyor section (24) will run between the two stations without being loaded with items for storage.
