Definitions

  • the invention relates to a device for producing a vacuum in rigid or flexible containers, in particular vacuum packaging machine with one Receiving container for the goods, a vacuum pump integrated in the receiving container and connecting hose that connects to one in the interior of the receptacle opening connecting bore is coupled.
  • Vacuum packaging machines of this type are used for certain supplies such as sliced sausage to make it last longer.
  • these foods such as liver sausage, salads, soft cheese and.
  • an appropriate container which is closed and connected to a vacuum pump is connected to draw vacuum in the container.
  • a vacuum pump is connected to draw vacuum in the container.
  • Bag filled with food whereupon the air is sucked out of the bag and the bag is then sealed.
  • the receptacle points to this a correspondingly large interior, in which a corresponding foil bag is hung to be filled with the food.
  • FR-A-2 397 330 is a device for producing a Vacuum in flexible containers known. This vacuum device is missing as well the container according to EP-A-O 419 736 any possibility of the ingress of liquids to prevent additional containers from being switched on.
  • the invention has for its object a device for vacuuming to create food-holding containers, their vacuum pump also at fallen containers before the penetration of food, in particular Liquids is protected.
  • the object is achieved in that on the outer wall of the Receptacle has a hose connector that has at least one hole to the interior Connection has, it is provided that the hose connected there with its free end to a container to be vacuumed, preferably a gastronorm container is connected, and that the connection hole for the Connection hose of the vacuum pump is provided on the upper edge of the receptacle.
  • the interior acts or acts Entire receptacle as a dummy boiler that initially draws in the liquids once and practically only then forwards them towards the vacuum pump, if the entire interior with the liquid or the corresponding food is filled out.
  • the vacuum pump namely sucks first via the connecting hose and the corresponding connection hole the interior of the receptacle empty to then or at the same time over the hose also act on the gastronorm container or other container. It is conceivable that the receptacle first of all by means of a corresponding circuit is applied to vacuum in order to only then also with a push to place the gastronorm container further behind accordingly under vacuum.
  • the interior of the Receiving container quite large, so that even with large streaks of bad luck actually occurring can be easily worked without being destroyed or damaged the vacuum pump is to be feared. If such a case arises, it becomes easy recognizable, because namely the lid of the receptacle consists of plexiglass, so that the user can quickly determine that "something is wrong”. It there is no damage, but it is then only necessary Clean the interior of the receptacle to then and then immediately to go back into operation.
  • Hose connection is arranged at the top of the receptacle.
  • the Hose connection is practically the entire volume of the receptacle as a buffer or as a dummy boiler are available so that even larger gastronorm containers can be vacuumed without any problems can, because even if you drop and suck in food damage to the vacuum pump cannot occur.
  • the invention provides that before the hose connection or before the bore has an air throttle protruding into the interior of the receptacle is arranged.
  • This air throttle which after an appropriate training of Invention is also arranged on the outlet-side hose connection bore, prevented moreover, that practically one originating from the vacuum pump Air blow to the flexible envelope in normal operation in the receptacle affects.
  • the sucked air flow is rather evened out by the air throttle, so that the problems described cannot occur, in particular the film can not be pressed or sucked onto the hose connection which would lead to significant problems.
  • this air throttle provides that it from a circular plate and a web fixed to the inner wall is formed. This about a 5-mark piece plate can be through a correspondingly simple web or two appropriately thin webs are supported so that they occur Loads are sufficient.
  • the one on the bore of the inlet hose connection seated air throttle has a special plate that is bent towards the inner wall executed outer edge.
  • that which is sucked in via the hose is sucked up Food, especially the liquid, and then hurled onto the plate via the lower outer edge to the inner wall of the receptacle, so that a quasi-continuous flow of the introduced food can be achieved leaves.
  • the device according to the invention is used as stated above of the receptacle used for other purposes, wherein according to the invention a quick and safe changeover is made possible by the hose connection and the hose end acting together as a quick release coupling are.
  • One part of the quick-release coupling sits on the hose connection, the other on the hose end, so that the parts are practically easy on each other can be plugged in to quickly establish a permanent connection. They can just as easily be taken apart again, for which purpose in usually a spring-loaded thrust ring is used.
  • the plugging on of the hose end and a response of the clutch the device according to the invention is ready for operation and virtually any external gastronorm container can be vacuumed without there is a risk that liquid will get into the vacuum pump. About swept away Liquid or other food residues would always be against the air throttle to be flung and then sink into the receptacle where they are easy to remove.
  • the hose connection can also according to a development of the invention in the lid of the receptacle be integrated. Similar to the arrangement at the top of the inner wall is also ensured with this arrangement that when sucking liquid into the Do not accidentally hold this liquid through the opposite Connection hole can be sucked in and brought to the vacuum pump.
  • the receptacle should be kept clear and not serve as a quasi blind boiler, it is possible according to the invention that the Hose connection with the connecting hose, which is in the double wall of the receptacle is installed, coupled and that the hose is connected via an intermediate Blind boiler, whose volume is about that of a gastronorm container corresponds.
  • an intermediate Blind boiler whose volume is about that of a gastronorm container corresponds.
  • the vacuum pump Similar to liquids, the vacuum pump also responds appropriate dusts are allergic, so that it is useful in such a case Case to switch a dummy boiler between.
  • the hose is on any one Place separately and opens into the blind tank at two points, so that the any food accidentally sucked in is collected and removed without any problems can be.
  • a particularly expedient version provides that the dummy boiler has two partial boilers which are detachably connected to one another, one of which Receiving hose ends and the other having the receiving space are.
  • the partial boiler receiving the hose ends can thus be installed in the Shape remain when the recording space should be fully filled.
  • the corresponding one The partial boiler is simply detached from the first partial boiler and then cleaned accordingly and emptied in order to be available for use again.
  • This training is also advantageous because the one having the recording space Partial boiler can of course be cleaned more easily than a correspondingly complex one assembled total boiler.
  • the side walls and / or the Bottom of the partial boiler inserted in the partial boiler having the receiving space are perforated.
  • the sucked-in food is thus initially in the for example sucked in a slightly more deeply arranged area of the upper partial boiler, to be separated into solid and liquid parts.
  • the liquid parts can drain through the side walls and / or the floor into the lower part of the boiler.
  • the bores, recesses or the like in the side walls and the floor must be designed so that there is a backwater or other Problems cannot come.
  • the invention is particularly characterized in that a device is created, which is particularly advantageous in the vacuuming of food can be used and the existing aggregates are used, at least in the large area.
  • the corresponding safety device is very Versatile use because an integrated system via the large receptacle is available that has high performance.
  • the other part of the Vacuuming device simply via plug connection to the interior of the receptacle connected so that the negative pressure prevailing there automatically and quickly sets in the container to be vacuumed located outside. Of the containers located outside and to be vacuumed are practically simply attached to the Interior of the receptacle connected via a hose, so that the Interior of the receptacle as a safety zone against the ingress of liquid into the vacuum pump.
