Definitions
- the invention relates to a device for evacuating and Fumigation of filled packs, such as from DE-AS 11 77 065 has become known.
- the well-known Device has a mouthpiece, the gassing openings down towards the opening of the shoulders of the Pack fin-like protruding head area of the pack and are directed sideways.
- the head area and opening always on same position in the chamber is with the known device a reduction in Residual oxygen content possible in the pack.
- Both Packs commonly used nowadays are made from relative thin and flexible packaging film is the exact one Position of the head area or opening of the pack in the chamber, however, is subject to fluctuations, so that not it is ensured that the downward facing circular openings of the fumigation tube always sufficient Shielding gas gets inside the pack. This results in undesirable high fluctuations in the Residual oxygen content inside the pack.
- the device for evacuation and gassing according to the invention of filled packs with the characteristic features of claim 1 has the advantage that almost regardless of the location of the opening of the package in the Always a sufficient amount of protective gas in the chamber Pack interior arrives, so that always very low Residual acid levels can be achieved.
- FIG. 1 shows an evacuation chamber in a simplified longitudinal section and Figure 2 a Fumigation device in a perspective view.
- the device 10 shown in Figure 1 for Evacuation and gassing of flexible foils Bag packs 1 have an evacuation chamber 11.
- the Evacuation chamber 11 consists of a stationary, in essential plate-shaped upper part 12, and an up and movable, pot-shaped lower part 13.
- a tube 14 with a not shown Vacuum source is connected in the evacuation chamber 11 .
- a sealing tool 15 for forming a closure seam in the Head area 2 of the bag package 1 arranged.
- the Sealing tool 15 has two movable against each other Sealing jaws 16, 17.
- the bag pack 1 is between two Holders 18, 19 clamped, the bag pack 1 during of evacuation and gassing in the evacuation chamber 11 fix.
- Above the sealing tool 15 and the The head region 2 of the bag pack 1 is one Fumigation device 20 arranged, just like that Sealing tool 15 preferably with the upper part 12 of the Evacuation chamber 11 is connected.
- the gassing device 20 has a strip-shaped, preferably cuboidal fumigation tube 21, the one slit-shaped opening 3 which is different from that of the Shoulders 4 of the bag pack 1 protrude like fins Head region 2 of the bag pack 1 is formed, covered.
- the opening 3 of the bag pack 1 facing bottom 22 of the fumigation tube 21 are several slit-shaped arranged parallel to each other Fumigation openings 23 are formed.
- the cheapest distance between the bottom 22 of the fumigation tube 21 and the In practice, opening 3 of bag pack 1 is a few Centimeters, and is determined on the basis of test series.
- the gassing openings 23 are one of the Fumigation tube 21 projecting feed 24 with a Shielding gas source connected.
- the arrangement of the Fumigation openings 23 is such that they are in essentially transverse, that is perpendicular to the opening 3 of the Extend bag pack 1.
- in 2 shows the fumigation tube 21 pivoted. In the operating position of the Fumigation tube 21, this is parallel over the Bag pack 1 aligned.
- the device 10 described above operates as follows: A previously filled and folded in the head area 2 Bag package 1 is in the lower end position Lower part 13 of the evacuation chamber 11 between the holders 18, 19 spent and held by them. Then will move the lower part 13 upwards, so that it with the Upper part 12 closes tightly. Then air is removed using the Vacuum source via the tube 14 from the interior of the Evacuated chamber 11 and the interior of the bag package.
- the aim is the air in the bag pack 1 or to reduce their oxygen to a longer Shelf life of the goods in bag 1, especially coffee. That goal will by means of simultaneous gassing of the goods an inert protective gas, in particular using nitrogen, supported.
- the bag pack 1 the protective gas with a certain overpressure, for example 0.5 bar, introduced.
- the inflowing protective gas causes a purging and Displacement of the inside of the bag package 1 air.
