Abstract: The invention concerns a box drying system for drying boxes, e.g. boxes for use in transporting food articles. The box drying system includes at least one box drying line of a plurality of possible box drying lines arranged in parallel, including at least two box drying elements disposed in series along a buffer/feeding track. The feeding path is provided for collecting a number of boxes for drying, wherein the collected boxed for drying are divided into at least two box drying groups, each box drying group comprising at least one box, and wherein drying of the box drying groups is divided between at least two box drying elements. Thereby is achieved a flexible box drying system that may rapidly handle even a large number of boxes.

Abstract: When, according to the invention, a washing system (1) is made of a pipe of synthetic material, where the pipe is divided into a washing tunnel (5) and a tank (6) separated by a package conveyor (3) and a drain bottom (7), a washing system is achieved, where the system may be advantageously by established by coupling a plurality of pipes together and by introducing a fully mounted drain bottom via an open pipe end. The selection of synthetic material as a pipe material results in great savings of material, while providing a tunnel which is stable and self supporting, and which is sound and heat insulating and hygienic, so that both the initial and the operating costs are reduced significantly.
