Abstract

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.

Description

464 126 i De båda koncentriska rören 4 och 5 som mellan sig upptager kammaren 6 är sammansvetsade utmed de ringformiga svetsarna 8 och 9 på sådant sätt att kammaren 6 blir gastätt försluten. 464 126 in The two concentric tubes 4 and 5 which occupy the chamber 6 between them are welded together along the annular welds 8 and 9 in such a way that the chamber 6 is gas-tightly closed.

Fyllröret 1 är i den version som visas i figuren avsedd att sammankopplas med ett rörsystem för tillförsel av fyllgods genom att kopplingsdelen 2 vid fyllrörets l övre del anslutes till nämnda här ej visade rörsystem. Då fyllgods tillföres genom fyllröret 1 kommer fyllgodset att passera den inre kanalen 7 och lämna fyllröret 1 genom dess mynning 3. Eftersom fyllgodset, då det utgöres av mejeriprodukter t.ex. mjölk, är relativt kallt vid fyllningstillfället, ca. 4°C och stora mängder fyllgods pumpas genom fyllröret 1 kommer fyllrörets inre rördel 4 att avkylas och bibringas samma temperatur som fyllgodset. Detta skulle normalt leda till att även fyllrörets utsida antar samma temperatur eftersom fyllröret l är tillverkat av metall, företrädesvis rostfritt stål, varvid i luften förekommande fuktighet skulle kondenseras på fyllrörets 1 utsida. Detta förhindras i det föreliggande fallet genom att fyllröret 1 består av två koncentriskt anordnade rördelar 4 och 5 vilka är åtskilda genom kammaren 6 i vilket det råder ett tekniskt vakuum. I praktiken går det inte att helt åstadkomma ett totalt vakuum i kammaren 6 utan praktiska försök har visat att ett tryck på max. 75 mm Hg är tillräckligt för att ge en god isolerande effekt mellan rören 4 och 5.In the version shown in the figure, the filling pipe 1 is intended to be connected to a pipe system for supplying filling material by connecting the coupling part 2 at the upper part of the filling pipe 1 to the pipe system not shown here. When filling material is supplied through the filling pipe 1, the filling material will pass the inner channel 7 and leave the filling pipe 1 through its mouth 3. Since the filling material, when it consists of dairy products e.g. milk, is relatively cold at the time of filling, approx. 4 ° C and large amounts of filling material are pumped through the filling pipe 1, the inner pipe part 4 of the filling pipe will be cooled and brought to the same temperature as the filling material. This would normally lead to the outside of the filling pipe also assuming the same temperature, since the filling pipe 1 is made of metal, preferably stainless steel, whereby moisture present in the air would condense on the outside of the filling pipe 1. This is prevented in the present case by the filling pipe 1 consisting of two concentrically arranged pipe parts 4 and 5 which are separated by the chamber 6 in which there is a technical vacuum. In practice, it is not possible to completely achieve a total vacuum in the chamber 6, but practical experiments have shown that a pressure of max. 75 mm Hg is sufficient to give a good insulating effect between pipes 4 and 5.

På grund av förekomsten av den evakuerade kammaren 6 avkyles således inte det yttre röret 5 hos fyllröret l eftersom det evakuerade utrymmet utgör en mycket god värmeisolator utan rörets 5 utsida antar i princip samma temperatur som den omgivande luften vilket innebär att i luften förekommande fuktighet inte kondenseras på rörets 5 utsida.Due to the presence of the evacuated chamber 6, the outer tube 5 of the filling tube 1 is thus not cooled because the evacuated space constitutes a very good heat insulator but the outside of the tube 5 assumes in principle the same temperature as the ambient air, which means that moisture present in the air is not condensed. on the outside of the tube 5.

Problemet vid tillverkningen av fyllröret enligt uppfinningen är att på ett effektivt sätt kunna evakuera den smala spalten mellan de koncentriska rören 4 och 5 och en lösning på detta problem som tillämpas är att svetsningen utföres i en vakuumkammare med ett automatsvetsaggregat som förenar de båda rören 4 och 5 med varandra utmed två på avstånd från varandra belägna ringformade svetsar 8 och 9. Eftersom svetsningen utföres i en vakuumkammare där det råder ett tryck på max. 75 mm Hg kommer trycket inuti kammaren 6 att få ungefär samma värde. 3 464 126 Fyllröret i enlighet med uppfinningen uppvisar många fördelar gentemot kända fyllrör och det har även visat sig att fyllröret då det användes för varmfyllning fungerar på samma värmeisolerande sätt, d.v.s. den yttre fyllrörsväggen antar inte samma höga temperatur som det inre fyllröret, vilket kan vara en fördel. Den huvudsakliga tekniska effekten med fyllröret enligt uppfinningen är dock att konstruktionen förhindrar att kondens bildas på fyllrörets utsida och som tidigare framhâllits är en sådan kondens synnerligen besvärande eftersom vattendroppar kan falla ner i de för fyllning avsedda förpackningarna, något som är ohygieniskt och direkt oacceptabelt vid fyllning av s.k. aseptiska förpackningar.The problem in the manufacture of the filling pipe according to the invention is to be able to effectively evacuate the narrow gap between the concentric pipes 4 and 5 and a solution to this problem which is applied is that the welding is carried out in a vacuum chamber with an automatic welding unit connecting the two pipes 4 and 5 with each other along two spaced apart annular welds 8 and 9. Since the welding is performed in a vacuum chamber where there is a pressure of max. 75 mm Hg, the pressure inside the chamber 6 will have approximately the same value. The filling pipe in accordance with the invention has many advantages over known filling pipes and it has also been found that the filling pipe when used for hot filling works in the same heat-insulating manner, i.e. the outer filling tube wall does not assume the same high temperature as the inner filling tube, which can be an advantage. The main technical effect of the filling pipe according to the invention is, however, that the construction prevents condensation from forming on the outside of the filling pipe and as previously emphasized, such condensation is particularly troublesome because water droplets can fall into the packages intended for filling, which is unhygienic and directly unacceptable when filling. of so-called aseptic packaging.
