Definitions

  • the present invention relates to a device intended to inject, into an enclosure, a cryogenic fluid, under a pressure greater than that which prevails in the enclosure.
  • a known device for implementing this process comprises several injection devices, 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 control valve, unique.
  • a device intended to inject into an enclosure a liquid capable of solidifying by expansion is known from the document EP-A-376 823 .
  • the patent EP-744 578 describes an injection device making it possible to avoid the inconveniences caused by blockage incidents under normal conditions of use. This device is such that the connection between the stop valve and the injection nozzle is calculated so that a blockage possibly formed in said connection and said nozzle following a closing of the injection valve can be expelled towards the enclosure by the liquid under pressure when the injection valve is reopened.
  • the device does not include means to prevent the formation of a blockage, but the expulsion of this blockage is possible as soon as it is restarted, so that it is possible to carry out a new injection at any time after the end of a previous injection period.
  • this device can be blocked by the entry of the material to be cooled into the injection device, and therefore the use of this device is limited to the cooling of solid products.
  • the present invention relates to an injection device intended to be fixed on the lower part of a container containing a product to be cooled in bulk, said injection device comprising a hollow cylindrical body in which is inserted a valve forced by a spring, said injection device comprising a through channel substantially parallel to said valve intended to be supplied with cryogenic fluid under pressure, one end of said through channel being connected to the cryogenic fluid supply system and the opposite end opening at the level of the valve seat.
  • the spring is calibrated such that the valve cannot slide without being subjected to a pressure of the cryogenic fluid at least equal to a threshold pressure.
  • a pressure of the cryogenic fluid at least equal to a threshold pressure.
  • the device according to the invention it is impossible for material contained in the enclosure to be introduced into the device and create blockages requiring dismantling and cleaning, whatever the physical state of this material.
  • the device according to the invention is therefore suitable for cooling products in liquid, pasty, solid or granular form.
  • pasty product we mean any product whose viscosity is between liquid and solid.
  • the device can advantageously replace the top cooling devices of tanks containing liquid or powdery products for which the prior art bottom cooling systems were not suitable.
  • the cryogenic fluid used is liquid nitrogen or liquid CO 2 , particularly when the product to be cooled is a food product.
  • the device according to the invention can be implemented with any type of cryogenic fluid.
  • the device can include several transverse channels, one of the ends of which opens at the level of the valve seat.
  • the device comprises n through channels, n being between 1 and 20, an even number, their number increases when the pressure of use of the cryogenic fluid decreases, said channels being arranged symmetrically with respect to the longitudinal axis of the valve.
  • two channels are arranged symmetrically with respect to the longitudinal axis of the valve.
  • the device of the invention is subjected to very significant temperature differences.
  • the wall of the enclosure on which the device is fixed is generally at room temperature, while the opposite part of the device which receives the supply of cryogenic fluid is at a temperature of -196°C. Icing phenomena on the external surface of the enclosure are therefore inevitable. There may therefore be sticking to the frosted wall of the enclosure of the material to be cooled.
  • the icing points become attachment points for the product contained in the enclosure. These points enlarge and eventually block the valve, no longer allowing the injection of cryogenic fluid.
  • a thermal bridge that is to say to insert a part of insulating material between the element of the device in direct connection with the arrival of cryogenic fluid and the element of the device placed directly on the wall of the tank, the constituent elements then being dissociable.
  • the thermal break can be made of any insulating material, in particular polymer resin or any other insulating plastic material.
  • the various constituent elements are made of steel, preferably of stainless steel with the exception of the thermal bridge which is made of an insulating material.
  • the different constituent elements are held together using a quick-disassembly connection or of the screwed or bayonet type or the like.
  • the device according to the invention must be able to be dismantled in particular with a view to calibrating the spring forcing the valve, or for cleaning which is obligatory in the case of food products and which may be made necessary by abnormal operation or even by pollution. accidental.
  • the device is connected to the cryogenic fluid supply via a flexible fluid conduit. This is to allow rapid dismantling. In fact, the flexible conduit does not have to be dismantled for cleaning.
  • cleaning is further facilitated by maintaining the various constituent parts using a quick mechanical holding system (“quick” connection).
  • quick mechanical holding system (“quick” connection).
  • the device of the invention being intended to be used under pressure, means are provided so that only authorized personnel can dismantle the device.
  • the constituent parts of the device are fixed together using tamper-proof screws and an anti-whiplash cable is fixed on the one hand to the flexible pipe, and on the other hand on either side of the “quick” connection, on the lower part of the device and on the upper part of it. Removal of the whip antibody cable is only possible using a specific key whose use is reserved for persons empowered.
  • the device according to the invention is fixed tangentially to the previously perforated wall of the enclosure.
  • the enclosure is a mixer
  • part of the cryogenic fluid is already transformed into a solid before coming into contact with the mass to be cooled.
  • the cryogenic solid is formed as soon as the fluid hits the valve seat in the space between the seat and the support. Taking into account the fact that it is the cryogenic solid which comes into contact with the material to be cooled, the cooling efficiency is therefore greater than that obtained with the devices of the prior art.
  • the product can of course be moving in the enclosure, which promotes heat exchange and therefore cooling of the contents.
  • the device according to the invention is fixed to the lower part of the mixing tank.
  • FIG. 1 shows the lower part of an enclosure 1 on the wall of which are fixed, preferably by welding, two cryogenic fluid injection devices 3 conforming to the invention.
  • the devices 3 are connected by a flexible pipe 4 and a heat-insulated pipe 5 to a solenoid valve 6 allowing the opening and closing of the supply of cryogenic fluid.
  • FIG 2 shows in more detail an injection device 3, comprising an upper part 7 whose free end 8 is intended to be fixed on the external wall of an enclosure, and a lower part 9, the two parts being connected by a connector rapid 10.
  • a flexible pipe 4 is connected to the lower part 9 of said device 3.
  • a whipping cable 11 connecting the flexible pipe 4, the lower part 9 and the upper part 7. This cable is fixed using hooks safety 12 so that only authorized people can undo it, for example for dismantling.
  • the injection device 3 comprises a body composed of two parts made integral, the lower part 9 and the upper part 7.
  • the upper part is itself made up of 3 elements, a substantially cylindrical external wall 14 made of stainless steel, one end of which comes indirectly to rest on the lower part 9 and the other end of which is intended to be fixed on the wall of the enclosure.
  • a piece of complementary shape called a thermal bridge, also hollow, insulating, inside which is placed a third element 16 in stainless steel crossed in its center by the valve 17 and by two through channels 18 opening onto the beveled upper part of the part 16 intended to receive the seat 13 of the valve 17.
  • the central through opening of the part 16 comprises three zones, a central zone 19a of diameter substantially equal to that of the valve so that the valve can be placed sliding in this zone and a lower zone 19b of greater diameter, of such that it can receive around the axis of the valve the spring 19 forcing it.
  • This spring 19 being held by the shoulder 20 formed between zones 19a and 19b.
  • the zone 19c is of beveled shape, of wider diameter at its free end, the shape of the bevel being adapted to sealingly receive the valve seat when the valve is forced by the spring.
  • the lower part 9 is made up of a single stainless steel element, of generally cylindrical shape. This part has a central blind recess 21 which when the device is mounted coincides with the opening 19b of the upper part. This recess is intended to receive the end of the valve held by the spring 19 and the calibration nut 22 of the spring.
  • connection 26 It also comprises on either side of the blind recess two vertical channels 23, 24 which in the mounting position open at one end each into a through channel 18 and the other end into a perpendicular channel 25, one of which one end opens onto channel 23 and the other is intended to be connected to the cryogenic fluid supply system via connection 26.
  • the lower part 9 is fixed to the central part 16 by screws 27 and 28.
  • Screw 28 is an anti-disassembly screw allowing compliance with safety standards for pressure devices.
