Definitions

  • the invention is intended in particular to provide a continuous stream of liquid nitrogen to a succession of cans scrolling on a conveyor, just before they are closed by crimping.
  • EP-A-109134 describes a dispensing device of the aforementioned type.
  • the structure of this device is complicated, in particular due to the arrangement of the pipes and the presence of a rotary metering disc, which moreover does not make it possible to obtain a continuous flow.
  • the invention aims to provide a reliable device whose production, use and maintenance are particularly convenient. To this end, it relates to a device for distributing a cryogenic liquid of the aforementioned type, characterized in that the three conduits pass through a sealed joint a plate fixed in the neck, at the inlet of the internal tank, and in that that the two openings are the single openings of the inner tank and the outer shell.
  • the dispensing device shown in the drawings in its position of use is intended to supply a continuous stream of liquid nitrogen to a succession of cylindrical metal cans (not shown) which scroll just below at high speed, contain a foodstuff such than a non-carbonated drink and are driven in horizontal translation by a conveyor (not shown).
  • This device essentially comprises a cryogenic container of conventional construction consisting of an internal tank 1 having a capacity of the order of one liter to several tens of liters, an external envelope 2 and a connecting neck 3, and arranged in an inverted position.
  • the internal reservoir 1 and the external envelope 2 which are for example made of aluminum, each have a cylindrical running part and two domed bottoms, the internal bottom being pierced with a large circular opening 4.
  • the neck 3 is a section of tube fixed with a seal at its ends around the periphery of the two openings 4, by means of respective solid rings 5, 6. These two rings are themselves welded around the openings 4 and the neck 3 may be made of stainless steel and be welded to the rings 5, 6.
  • the ring 5 defines inside the neck 3 a horizontal annular shoulder 7 provided with several holes and facing downwards.
  • annular space 8 with vacuum-insulated insulation, the pumping being carried out by a connector 9.
  • the insulation could be produced from an injected insulating material such as polyurethane, or by any other suitable means.
  • the tubes 11 and 21 are welded to the plate 10, while the removable members 15 and 19 are fixed thereto by means of seals. Likewise, a seal is provided between the ring 5 and the plate 10.
  • the device also comprises a rigid ring 23 welded to the upper end of the casing 2 and provided with hooks 24 (one of which has been shown in FIG. 1), and a lower cover 25.
  • the latter consists of on the one hand a ferrule 26 welded to the lower end of the casing 2 and provided with at least one handling handle 27, and on the other hand a lower cover 28 detachably fixed on the ferrule 26 and crossed by the vent 11 and by the pipe 14.
  • connection box 29 (not shown in FIG. 2) is fixed to the ferrule 26.
  • This box comprises a solenoid valve assembly 30 - connection 31 mounted at the end of the pipe 12, a connection 32 to which the tube ends. 21, and an electrical connector 33 to which the electrical wires for controlling the solenoid valves 18 and 30 end.
  • the space remaining free in the neck and between the envelope 2 and the cover 25 is filled with an appropriate thermally insulating material 34.
  • the device In service, the device is suspended by the hooks 24 on an appropriate support (not shown), the axis of the pipe 14 meeting at a right angle to that of the conveyor which carries the boxes to be pressurized.
  • connection 31 There is connected to the box 29 a line for drawing off a storage of liquid nitrogen under a pressure greater than atmospheric pressure (connection 31), a pressure gauge (connection 32) and an electrical supply cable (connection 33).
  • the solenoid valve 18 being closed, the solenoid valve 30 is opened, which causes the filling of the reservoir 1 to a high level detected by the pressure gauge.
  • the solenoid valve 18 is opened, which is fully submerged and therefore does not provide heat.
  • Frank liquid fills the sleeve 15 passes through the calibrated orifice of the insert 17 and flows freely in a thread along the axis of the pipe 14, without touching the latter.
  • the nitrogen vaporized in the tank 1 is evacuated at atmospheric pressure through the vent 11.
  • the jet of liquid nitrogen can be stopped at any time by simply closing the solenoid valve 18.
  • the filling of the reservoir 1 is carried out automatically by controlling the solenoid valve 30 in all or nothing from signals supplied by the manometer in order to maintain an approximately constant height of liquid in the tank and, consequently, obtain uniform conditions for the distribution of liquid nitrogen in the boxes to be pressurized.
  • the external part of the vent 11 can be shaped into a tunnel 11 A overhanging the conveyor in order to create a more or less inert protective atmosphere in the gas volume existing in the boxes to be pressurized.
  • the connector 19 can be omitted, the electrical wires 20 passing along the vent 11.
  • the vent 11 can be bent at its upper end and be provided with a cage containing a float.
  • the vent 11 closes automatically when the liquid reaches the high level, and the pressure balances with that of the filling line (for example two absolute bars).
  • the device according to the invention applies to various cases where it is necessary to obtain a reliable and controlled injection of a cryoene franc liquid, in particular at low flow rate.
  • the pipe 14 can be connected to a horizontal manifold itself provided with several discharge orifices arranged at several points in a packaging chain, for example to provide inerting or localized cooling.
