Definitions
- the present invention relates to a head supply of a cryogenic liquid intended to be mounted on the end of a powered transfer line by a source of said liquid, said line comprising a downstream outlet for said liquid.
- Such transfer lines find their application in various fields of technology, in particular food or pharmaceutical, where it is necessary to deliver doses of cryogenic liquid, at a higher or lower rate, and continuously or discontinuous.
- cryogenic liquid is particularly difficult to reach. Indeed, the containers scroll on a conveyor, most often at a very high rate high and sometimes variable, reaching up to several dozen containers per second.
- the invention relates to the production of a supply head cryogenic liquid, easily adaptable to a transfer line of said liquid, which responds to food hygiene requirements and is likely to deliver a constant, frank and constant flow of cryogenic liquid straight.
- the invention also relates to a line of transfer of cryogenic fluid, supplied by a source of said cryogenic liquid, of the type comprising a conduit central passage of said liquid, and an envelope exterior, characterized in that it is equipped with a head as defined above.
- the invention finally relates to an installation for supplying cryogenic liquid, of the type comprising a source of said liquid and at least one line of transfer of this liquid, characterized in that the line of transfer conforms to the definition above.
- FIG. 1 shows an installation 2 of supply of a cryogenic liquid, in this case liquid nitrogen.
- This installation includes a tank 4 temporary storage, arranged on a frame 6.
- the liquid nitrogen supply to reservoir 4 is provided by a source not shown, and controlled by control means 8 known as such.
- the storage tank includes, in its part upper, a valve 10 allowing it to communicate with the outside, so that he reigns within this tank a pressure slightly higher than the atmospheric pressure.
- the reservoir 4 is extended, at its end lower, by a transfer line 12 on which is adapted a supply head 14 conforming to the invention, by means of a clamp 16.
- the installation allows to deliver a quantity predetermined liquid nitrogen inside boxes of canned cylinders 18 running on a conveyor 20 in the direction of arrow F.
- These containers contain for example fruit juice, and scroll at a speed several tens per second.
- Liquid nitrogen is delivered in the form of a continuous vertical jet.
- a lid higher 22 is reported on the latter by means of any suitable process, such as welding or crimping.
- the liquid nitrogen thus delivered therefore allows made of its vaporization, on the one hand to stiffen the container to avoid deformation, and other part of extending product shelf life food, by inerting.
- FIGS 2 and 3 show the line of transfer 12 equipped with its terminal head 14 supply.
- This line 12 is of a type known per se, and includes a central duct 24 made of stainless steel in which circulates the liquid, and a sheath formed by a insulating lining 26 surrounding said conduit, thus that a peripheral casing 28 also made of steel stainless.
- the inter-wall space of line 12 is under empty and is limited, downstream, by a shutter 29.
- the casing 28 is provided at its end downstream, considering the direction of flow of the liquid, an external flange 30 projecting radially outwards, intended to receive the hose clamp 16 as will be described by the after.
- the collar 30 comprises, at its periphery interior, a recess 32 for receiving a ring adapter 33, as will also be described by the after.
- the conduit 24 extends beyond the shutter 29. It is extended by a steel end fitting 34 stainless steel with a central bore 36 for passage of the liquid.
- This end piece 34 has a curved outer profile defined in particular by a hemispherical portion 38, extending from the periphery of the downstream port 39 of bore 36.
- This orifice 39 defines the downstream orifice of line 12.
- the supply head 14 includes a nozzle liquid discharge center 40, made in Teflon. Its outer periphery is substantially cylindrical, and has a peripheral shoulder upper 42, projecting outwards.
- a through opening for the passage of liquid is formed in the nozzle 40.
- This opening is constituted by a central channel 44 of circular section extended at the top by a funnel frustoconical 45 flaring towards the top of the nozzle.
- the downstream orifice 47 of the central channel 44 defines the orifice downstream of the supply head.
- the nozzle 40 takes a tight linear support, by its frustoconical wall 45, against the spherical surface of the end piece 34 of the conduit 24 of the line of transfer 12. In this way, the transfer zone 48 of the liquid between line 12 and the nozzle, located immediately downstream of the downstream orifice 39 of the end piece, is well insulated mechanically and thermally.
- the nozzle 40 is surrounded by a steel frame stainless formed by a base or bottom plate 56 of substantially circular exterior profile, and of a cylindrical peripheral envelope 58 fixed on the base by welding at the outer periphery of the latter.
- the base 56 includes a central zone 62 in extra thickness in which an opening is provided circular for passage with little clearance from the nozzle 40.
- the envelope 58 has, at its upper part, a flange 64 projecting outwards, and provided with an internal recess 66.
- This flange 64 and this recess 66 are intended to cooperate with the flange 30 and the corresponding offset 32 of the envelope 28 of the transfer line 12, like this will be described later.
- a layer 68 of insulating glass foam is disposed against the inner periphery of the casing 58 of the chassis, and rests on the base 56.
- One piece cover 70 in stainless steel covers the top and the interior of this insulating layer 68.
- This part covering 70 includes a base 72 welded to the extra thickness 62 of the base 56, a circular wall 74 extending along the inner periphery of the layer insulating 68, and an upper edge 76 welded on the inner periphery of the envelope 58.
- a passage opening with a small clearance of the central member 40 is further provided in the base 72 of this covering part 70.
- An intermediate crown 78 in Teflon is disposed in a lower counterbore of the base 56, and surrounds the lower part of the nozzle 40.
- This crown 78 makes it possible to reduce the surface heat exchange between the stainless steel base 56 and the Teflon nozzle 40, so as to limit the supply of heat to the cryogenic liquid flowing in the channel 44 of the central organ.
- stainless steel guide sleeve is supported on the upper face of the base 70 of the covering part, and surrounds the nozzle 40 on a part substantial height of it.
- This scabbard 80 has, at its lower part, a protruding rim 82 outwards to which the end is welded bottom of a bellows 84 made of stainless steel, formed by a thin and large sheet length, folded over several times. The upper end of this bellows is welded to the rim 54 of the peripheral flange 52 of the member central 40.
- This bellows 84 therefore constitutes a means of return elastic allowing the portion to be pressed in service upper frustoconical 45 of the nozzle 40, against the nozzle terminal 34 of conduit 24 of transfer line 12, in order to avoid any heat supply towards the flowing liquid.
- the nozzle 40 is thus free to slide axially with respect to the chassis, which is fixed to the transfer line 12 as will be explained below, and is guided by the internal surfaces respectively of the sheath 82, of the base 72 of the part covering 70, and the extra thickness 62 of the base 56.
- This elastic return means therefore makes it possible to get rid of any differential dilation between different components of line 12 and the head 14, which could lead to a separation of the end piece 34 relative to the nozzle 40, and therefore to a untimely spraying of the cryogenic liquid by heat supply.
- a deflector 86 for diverting air and scraping, as well as a jet protection cup 88 liquid nitrogen, are also reported on the face lower of base 56.
- the deflector 86 made of stainless steel, consists of a base plate 90 having, in view from above, substantially V-shaped, and widening towards downstream, referring to the direction of movement of containers 18 on the conveyor 20.
- This base plate has a nose 92 projecting upstream by relative to the outer periphery of the envelope 58 of the head 14.
- the deflector 86 further comprises a wall lateral 94 extending vertically downwards from of the periphery of said base plate 90. This wall side 94 protrudes downward from the downstream end of the liquid passage channel 44 cryogenic.
- this deflector protruding at both downstream and down, allows it to divert the air current caused by high speed movement of the containers 18 on the conveyor 20. It can also assume a scraping function aimed at remove residual foam on top containers, before sealing them, which thus avoids any blockage of channel 44 of the head 12 by the foodstuffs contained in the containers 18.
- the cup 88 made of Teflon, includes a base 96 resting against the base plate 90 of the bow, as well as a side wall 98 extending towards the bottom.
- This side wall is of circular section and has substantially the same outside diameter as the envelope 58 of the head.
- This side wall extends downward in projecting from the downstream end of channel 44 of passage of the cryogenic liquid, but remains behind by relative to the lower edge of the deflector 86. In this way is established, inside the volume V defined by the dish, an atmosphere saturated with nitrogen gas. This therefore prevents ambient air from approaching the end of the canal, near which a temperature prevails well below 0 °, which eliminates any risk of ice formation due to air humidity.
- the deflector 86 and the cup 88 are respectively provided with a central free orifice passage of the central organ 40, and are fixed during of the same operation against the base 56 of the chassis of the head, for example by means of screws 99.
- the adapter ring 33 in Teflon in the shape of a crown, is placed between the downstream end of the transfer line 12, and the upstream end of the supply head 14.
- This ring has a T-shaped cross section, of which the core 102 is turned radially outward, and is center, by its two wings 104, in the recesses respective 32, 66 with which the flanges 30 are provided, 64 opposite line 12 and head 14.
- Soul 102 is sandwiched between the facing planes of the two flanges.
- An EPDM O-ring 106 is also disposed at the outer periphery of the adapter ring 33, and is therefore crushed between the flanges respectively 30, 64 of line 12 and of head 14.
- the clamp 16 of section substantially C-shaped and formed stainless steel, also encloses by the face interior of each of its wings 108, the flanges 30 and 64.
- the invention achieves the objectives previously mentioned.
- the supply head conforms to the invention is easily adaptable on the line of transfer, since their mutual bond makes only intervene easily removable elements.
- the user can drill channel 44 himself desired diameter.
- the supply head according to the invention meets food hygiene requirements, since it only uses materials such as steel stainless and Teflon, which are compatible with peracetic acid used for cleaning the installation.
- the path that nitrogen travels liquid in the head has no recesses likely to induce possible water retention or any other product.
- the head according to the invention makes it possible to minimize heat input to the liquid cryogenic.
- the connection between the transfer line and the supply head is indeed only consisting of elements reported in the vicinity of outer envelopes of the line and head.
- junction area between the paths of passage of the liquid respectively inside the line and head is well thermally insulated, everything first because of the use of a central nozzle in insulating material, then through the use of a elastic return means making it possible to press, in service, the upstream end of the central passage nozzle liquid against the end of the line transfer, and finally due to the profiles of the nozzle and the nozzle.
