Definitions

the present invention relates to a filling pipe on a packing machine consisting of two concentrically arranged metal pipes.
the product is filled at a relatively low temperature, approx. 4-6°C, into previously arranged packing containers or into a packing tube.
condensation occurs on the outside of the filling pipe, and such condensation is undesirable, since bacteria present in the air can adhere to the water drops which are formed by condensation and which subsequently can drop off from the outside of the filling pipe down into the packages. From a hygienic point of view any condensation on the outside of the filling pipe is thus undesirable and it is endeavoured to find means to prevent any formation of condensation.
One solution of the problem is offered by the present invention which relates to a double-walled filling pipe, consisting of two concentrically arranged metal pipes, which at their ends are welded together in a gas-tight manner so that a gas-tight chamber is formed between the pipes, which is evacuated. Owing to the evacuated chamber with annular cross-section between the inner and outer pipe of the filling pipe a very good thermal insulation is obtained, which means that the cold product which cools down the inner wall has no decisive cooling effect on the outer metal pipe, so that condensation is largely prevented.
the filling pipe shown in the Figure is designated 1 and it comprises an upper coupling part 2 and a lower outlet part 3. As is evident from the Figure the righthand part of the filling pipe is shown cut-through whereas the lefthand part is shown in uncut projection.
the central part of the filling pipe 1 consists of two concentrically arranged pipes 4 and 5 and a chamber 6 formed between the said pipes 4 and 5.
the inner filling channel of the filling pipe is designated 7.
the two concentric pipes 4 and 5, which between them accomodate the chamber 6, are welded together along the annular welds 8 and 9 in such a manner that the chamber obtains a gas-tight seal.
the filling pipe 1,in the version which is shown in the Figure, is intended to be coupled together with a pipe system for the supply of contents, in that the coupling part 2 on the upper part of the filling pipe 1 is connected to the said pipe system, not shown here.
the contents When the contents are supplied through the filling pipe 1 the contents will pass the inner duct 7 and leave the filling pipe 1 through its outlet 3. Since the contents, when they are constituted of dairy products such as e.g. milk, are relatively cold at the point of filling, approx.
the inner pipe part 4 will be cooled down and assume the same temperature as the contents. Normally this would mean that the outside of the filling pipe would assume the same temperature, since the filling pipe 1 is made of metal, in particular stainless steel, so that moisture occurring in the atmosphere would condense on the outside of the filling pipe 1. This is prevented in the present case in that the filling pipe 1 consists of two concentrically arranged pipe portions 4 and 5 which are separated by the chamber 6 wherein a technical vacuum prevails. In practice it is not possible to achieve a total vacuum in the chamber 6, but practical experiments have shown that a pressure of max. 75 mm Hg is sufficient to provide a good insulating effect between the pipes 4 and 5.
the outer pipe 5 of the filling pipe 1 is not cooled down, therefore, since the evacuated space constitutes a very good thermal insulator but the outside of the pipe 5, in principle, assumes the same temperature as the surrounding air which means that moisture occurring in the atmosphere does not condense on the outside of the pipe 5.
the problem in the manufacture of the filling pipe in accordance with the invention lies in being able to evacuate the narrow gap between the concentric pipes 4 and 5 and a solution of this problem which is put into practice is that the welding is carried out in a vacuum chamber with an automatic welding unit which joins the two pipes 4 and 5 to one another along two annular welds 8 and 9 situated at a distance from one another. Since the welding is carried out in a vacuum chamber where a pressure of max. 75 mm Hg prevails, the pressure inside the chamber 6 will attain approximately the same value.
the filling pipe in accordance with the invention presents many advantages as against known filling pipes, and it has been found too that when the filling pipe is used for hot filling it functions in the same thermally insulating manner, that is to say, the outer filling pipe wall does not assume the same high temperature as the inner filling pipe, which may be an advantage.
the main technical effect with the filling pipe in accordance with the invention is that the design prevents the forming of condensation on the outside of the filling pipe and such a condensation, as pointed out earlier,is particularly troublesome, since water drops may fall down into the packages intended for filling, which is unhygienic and quite unacceptable in the filling of so-called aseptic packages.
