    • 专利摘要:
    The invention relates to a product filling pipe (1) to a packing machine for liquid contents such as milk. The filling pipe (1) consists of two concentric pipes (4,5) of metal which between them form a vacuum chamber (6). The double-walled filling pipe (1) is manufactured by the welding together in a vacuum chamber of two concentrically arranged pipes (4) and (5) along the annular weld joints (8) and (9). When a product which is considerably cooler than the surrounding atmosphere is supplied through the inner pipe (4) the outer pipe (5) will not be cooled down to an appreciable extent, since the evacuated space (6) in between constitutes a good thermal insulator.

    WITH
    The invention relates to food packaging, in particular to a filling tube in a packaging machine.
    In modern high-performance packaging machines for products such as milk, the product is filled at a relatively low temperature (approximately 4-6 ° C) in pre-installed packaging containers or in a packaging tube. A liquid filling device is known; the filling pipe has an intermediate section with double-walled pipes.
    Due to the low temperature of the product being filled on the outside of the filling tube, condensation occurs and this condensation is undesirable because bacteria present in the air can stick to water droplets that form during condensation and which can then get from the outside of the filling tube into packages . From a hygienic point of view, any condensation on the outside of the filling tube is therefore undesirable and therefore means are sought to prevent any formation of condensation.
    The aim of the invention is to improve hygiene.
    The filling pipe is made with two walls in the form of two concentric metal pipes, which are welded together along the edges by gas-tight welding so that between them a gas-tight chamber is formed, from which air is evacuated. Due to the discharged chamber with an annular cross section between the inner and outer tubes of the filling tube, very good thermal insulation is achieved, which means that the cold product that cools the inner wall does not have a serious cooling effect on the outer metal pipe, resulting in condensation into a large least it is preventable.
    The drawing shows a filling pipe.
    The filling pipe 1 includes the upper connecting part 2 and the lower output part 3. The filling pipe 1 consists of two concentric metal pipes 4 and 5 installed with one gap relative to the other with the formation of a closed chamber 6 with a rarefied atmosphere. Two concentrically mounted pipes 4 and 5 are welded to each other and the external pipe 5 is connected along its edges with the internal pipe to form a path 7 by means of welds 8 and 9.
    The pressure inside the closed chamber 6 can reach a pressure of less than 75 mm Hg.
    to provide a well-insulating effect between pipes 4 and 5. The filling pipe is intended to be connected to the pipeline system for supplying the product, while the connecting part 2 located on the top of the filling pipe 1 is connected to the said pipeline system. When the content is fed through the filling pipe 1, it passes through the internal path 7 and leaves the filling pipe 1 through its outlet. Since the fillers, when they are dairy products, have a relatively low temperature at the point of filling (approximately 4 ° C) and are pumped to large
    0 quantities through the filling pipe 1. A part of the inner pipe 4 is cooled and takes on the same temperature as the contents.
    This usually means that the outer side of the filling pipe will take the same temperature, since the filling pipe 1 is made of metal, in particular stainless steel, and the humidity present in the atmosphere will condense on the outside of the filling pipe 1 This is prevented by the fact that the filling tube 1 consists of two concentrically arranged tubes 4 and 5, which are separated by chamber 6, where technical vacuum prevails. Due to the presence of chamber 6, the outer tube 5 of the filling tube 1 is not cooled because the vacuum This space is a very good thermal insulator, and the outer side
    0 pipe 5 assumes the same temperature as the ambient air, the humidity present in the atmosphere does not condense on the outside of pipe 5. Welding pipes 4 and 5 is carried out in a vacuum chamber by an automatic welder that connects two pipes 4 and 5 to each other. with the other along the two ring seams 8 and 9, located at some distance from each other. Since welding is carried out in a vacuum chamber, where
    0, the maximum pressure of 75 mm Hg prevails, the pressure inside chamber 6 will have approximately the same value. If the filling tube is used for hot filling, it acts by that
    5, however, the thermal insulation path, i.e., the outer wall of the filling tube does not accept the same heat that the inner filling tube has.
    The effect of using the proposed filling tube is that
    This structure prevents the formation of metal pipes, from condensation on the outside, so that, in order to increase
    a full pipe, moreover, such condensed hygienic, pipes are installed with a backlash, if they are not removed, brings one more relative to the other with the formation of unpleasantness, since the water5 of a closed chamber with a discharged
    Drops may fall into the packaging, prednazna-atmosphere, while the outer tube by
    for the filling, which is unhygienically and its edges connected to the inner piperoof completely unacceptable when filled with the slab by means of a weld. aseptic packages.
