Definitions
- the invention relates to the field of isothermal containers comprising, above a storage compartment, a cryogenic compartment for the storage of dry ice ensuring the conservation of fresh or frozen products.
- a container according to the preamble of claim 1 is for example known from the document EP-A-0 823 600.
- It relates more particularly to the compartments cryogenic whose front face is equipped with at least one opening connectable to the injector of a dioxide injection device carbon in liquid phase, and at least one opening which can be connected to a suction source to recover carbon dioxide, during snow formation.
- this consists of a removable tray or a drawer, this tray or drawer being slidably mounted in slides arranged in the inner wall of the container.
- the object of the present invention is to remedy this disadvantage by providing an insulated container comprising a jet breaker device for a tray or drawer cryogenic compartment supplied by an external nozzle, reducing the effects of pressure on the tank and abrasion on the retention wall snow, but also improving snow filling.
- the jet breaker is consisting of a tubular mesh of pressure-resistant material which, arranged in the snow storage chamber, is an extension of the opening for the injector of an injection device, is linked to the wall front of this drawer by one of its ends, is closed at its other end and comprises, at least in part of its wall, meshes, forming a regular lacunar network letting pass the gas but also the snow forming inside the trellis.
- the ratio S1 / S2 between the perforated surface S1 and the surface S2 of the part allowing the snow to pass through the tubular trellis is between 0.45 and 0.8.
- the tubular trellis is provided with mesh over its entire periphery and has, on its upper part and on its entire length, a semi-cylindrical mesh cover corresponding.
- This hood opposes the exit of the snow upwards, in direction of the porous sheet of gas and therefore opposes its clogging by snow, which guarantees gas evacuation. It also promotes snow distribution over the entire bottom of the cryogenic compartment.
- the reference numeral 2 denotes, so general, an isothermal container 2 with a front door 3 and whose cavity internal is provided with slides, respectively lateral 4 and posterior 5, in which the edges, respectively lateral and posterior, from the bottom 6 of a drawer 7.
- This drawer divides the internal cavity of the container in an upper cryogenic compartment A and a compartment lower B for storage of fresh or frozen products.
- the drawer 7 has a front wall 8, capable of being fitted into an appropriate rebate of the container, and its bottom 6 is integral with a parallelepipedic tank 9 in form of box open upwards and whose upper opening is closed by a sheet 10, porous to gas but not to dry ice.
- the drawer is, for example, made by rotational molding of polyethylene and its hollow walls are filled with an insulating material, such as than polyurethane foam 12.
- Room C communicates with the exterior by an opening 14, visible in FIG. 1, formed in the wall front 8 of the drawer.
- the gas accumulation chamber D it communicates with the outside through an opening 15, formed in the same wall 8.
- the tank 9 is equipped with a jet breaker 20 which is consisting of a tubular mesh 21 made of pressure-resistant material, extending longitudinally inside the tank. Its anterior end is fixed on the internal face of the front wall 8, in the extension of the opening 14, for example by a flange 22. The other end of the jet breaker is closed and shaped as lug 23. This is fixed by a screw transverse not shown, on a step 24 projecting from the bottom of the tank and disposed near the rear wall 6a of this tank.
- Leg 23 is advantageously formed by flattening the tubular mesh in one of its diametrical plans.
- This tubular mesh is crossed by meshes 25.
- the perforations 25 are distributed in the part of the tubular mesh 21 which makes opposite the bottom 6 of the tank, that is to say over substantially its half lower, which implies that its upper part has no perforations.
- the trellis tubular 21 is constituted by a metallic fabric, bent to form a sleeve whose longitudinal edges are connected by a few points of solder 26.
- the upper part of the body, thus obtained, is covered by a semi-cylindrical cover 27, formed by a metal sheet which, after putting in shape, is fixed to the canvas by welds 28.
- the metallic canvas is also welded to the flange 22, so as to form an assembly monolithic with this flange.
- the S1 / S2 ratio between, respectively, the total area perforated S1 of the meshes 25 used and the surface S2 of the cylindrical part tubular mesh allowing snow to pass, is between 0.45 and 0.8, and that whatever the dimension of the meshes which is defined according mechanical strength of the jet breaker.
- the pressurized jet emitted by the injector 18 remaining outside the jetbreaker is distributed longitudinally inside the body tubular of the breakwater 20 where it immediately turns into snow and gas. Due to its rigid structure, the jet breaker absorbs without deformation the forces resulting from this projection, and already reduced by the relaxation immediate. Furthermore, the non-perforated part, constituted by the cover 27, opposes any upward projection, in the direction of the sheet 10, and therefore prevents it, which is more fragile, from being subjected to accelerating forces its wear by abrasion.
- the gas escapes from the tank through the sheet 10, as shown in arrow 33, and from there goes to room D where it is sucked by means connected to the opening 15 formed in the wall end.
- the jet breaker is inexpensive and its low cost is more than made up for by longer service life of the drawer, since, during repeated injections, its resistance is not affected and therefore can be used safely for many fillings.
- the jet breaker is porous to snow over its whole periphery.
- it can be juxtaposed with another jet breaker, arranged in the same bin or in a neighboring bin.
