Definitions

  • the present invention relates to a device intended for injecting, into an enclosure, a liquid under a pressure higher than that prevailing in the enclosure, this liquid being liable to solidify by expansion up to the pressure in the enclosure.
  • the invention was developed to solve problems encountered during the cooling of the contents of a kneader by injection of liquid CO 2 , but it is clear that the invention can have many other applications.
  • a known device for implementing this method comprises several injectors, arranged in the bottom of the tank, and supplied with liquid CO 2 by a set of pipes, this set being provided with a common, single control valve.
  • Provision may be made for the pipes connecting the valve the injectors are flexible, allowing disassembly, and consequently accelerates the restarting of the system. This dismantling is however an operation relatively long and painful.
  • a device for injecting in an enclosure a susceptible liquid to solidify by relaxation is known from document EP-A-376 823.
  • the object of the present invention is to eliminate these disadvantages, and to provide a device with which the clogging incidents just reported cannot occur under normal conditions of use.
  • the invention provides a device according to claim 1 below.
  • the invention does not include means for prevent plugging, but it helps the expulsion of this plug upon restarting, so that it is possible to re-inject at any time after the end of a previous period injection.
  • the valve comprises a valve body linked directly to the injector.
  • the passage between the valve and the injector can be made as short as possible, which decreases the importance of the plug accordingly.
  • valve body and the injector into an inseparable whole, because, normally there is no need to disassemble from the whole.
  • Cleaning may be required by a abnormal operation, for example a blockage of the injector by a mass of the material contained in the enclosure, or by accidental pollution. Cleaning is in any case compulsory in the case of food products.
  • an organ valve actuation mounted on the valve body, is connected to a fixed source of fluidic or electrical energy, by a flexible fluidic or electric conduit.
  • Disassembly is thus further facilitated, because the flexible duct does not have to be dismantled for cleaning.
  • Figures 1 and 2 show an enclosure 1, here a kneader, whose outer wall 2 is visible in section in Figure 2.
  • the enclosure 1 is equipped with a ramp consisting of several injection assemblies 3, supplied with CO 2 liquid by a heat-insulated supply pipe 5, a manifold 4 and flexible pipes 6, each provided, at the outlet of the manifold 4, with a shut-off valve 7.
  • each injection set includes a shut-off valve spherical 8, the inlet passage of which is connected to the flexible 6.
  • a calibrated throttle suitable for injection and carbon dioxide expansion.
  • This throttle is integrated in the valve body.
  • the injection assembly also includes a short straight tube 9 coaxial at the outlet passage of the valve 8 and connected, by a connector 10, to a threaded sleeve which extends an injection nozzle 11 coaxial with the tube 9.
  • the valve outlet passage, the tube 9 has an inner diameter smaller than that of the nozzle 11.
  • the nozzle 11 is fixed by welding to the wall 2 of the tank 1, and passes through this wall. It can be fitted internally with a sleeve insulation preventing the transmission of cold to the walls of the tank, thus avoiding the freezing of the meat around the injection inputs.
  • the connector 10 is a quick-disconnect connector, from the screwed type. It could also be of the bayonet type or similar. As shown in the figure, the axis common to the nozzle 11 and to the ball valve 8 is directed towards the bottom making an angle of about 10 ° with the horizontal, depending a known technique, intended to obtain good penetration of the refrigerant to the part bottom of the enclosure.
  • the valve 8 is associated with a pneumatic operator 12 and forms with it a set delivered all assembled by the valve manufacturer.
  • An electropneumatic pilot 13 is fixed on operator 12, and supported by him.
  • the operator 12 carries also a sensor 14 intended to allow the control of its position.
  • a connecting piece 15 which has the shape of a section of square section tube, with axis parallel to the passage of the valve. This part 15 is crossed by the control shaft which connects the operator 12 to the valve 8.
  • the supports 16 relating to the different assemblies injection 3 of the ramp together carry a chute 18, at inside which conductors are placed electrical and compressed air lines, not shown.
  • the chute also contains, near each injector 3, a connection box 19 connected by flexible conduits and conductors 20, 21 to operator 15, to pilot 16, and to the position sensor 14.
  • the reference 22, at Figure 3, designates a connecting conductor between the box connection and a control member, not shown.
  • the valve 8 In operation, the valve 8 is open, and the liquid CO 2 is sent directly, along a rectilinear path, from the connector 10 into the interior of the enclosure 1, through the nozzle 11.
  • the pilot 13 controls the actuator 15, which closes the valve 8. Only part of the liquid CO 2 which is between the valve 8 and the interior of the enclosure 1 will relax by forming a small plug of dry ice. When resuming operations, if this plug has not disappeared, it is easily expelled by the pressure of the liquid CO 2 through the rectilinear conduit which ends inside the enclosure 1.
  • FIG 4 is shown a variant of production of an injection assembly.
  • This includes essentially an injection nozzle 40 on which is connected a solenoid valve 42 supplied from a pipe insulated supply via a bypass hose 44.
  • the nozzle 40 is formed by a metal sleeve with stepped interior section, increasing in the direction of circulation of carbon dioxide from a diameter of 5 mm up to a diameter of 7 mm.
  • the outlet end of the nozzle 40 is welded to the outer metal wall 2 of the enclosure, so that its outlet axis is oriented downwards and defines with the horizontal an angle of 10 °.
  • the outlet end of the nozzle is bevelled to follow the wall curvature 2.
  • the length of the nozzle is for example around 7 cm. It is as small as possible and is limited to the necessary length to obtain sufficient clearance relative to wall 2 for mounting the solenoid valve 42.
  • the solenoid valve 42 is screwed axially directly at the inlet of the nozzle 40. It comprises an associated valve 46 to electromagnetic actuation means 48. The input of the valve 46 is connected to the flexible pipe 44 for supplying the dioxide liquid carbon.
  • the actuating means 48 comprising a solenoid are powered by an electrical conductor 50 connected to an appropriate control device (not represented).
  • the valve 46 includes a shutter intended to shut off a valve seat.
  • the passage in the seat of valve forms a calibrated throttle suitable for injection and the expansion of carbon dioxide.
  • the dimensioning of the passage depends mainly on the supply pressure and the flow of carbon dioxide.
  • the power supply actuating means 48 causes the opening or closing the valve 46, thus allowing the control of supplying the enclosure with carbon dioxide.
