Definitions
- the present invention relates to a device for injecting, in a chamber, a cryogenic fluid under a pressure greater than that prevailing in the chamber.
- a known device for the implementation of this method comprises several injection devices, arranged in the bottom of the tank, and supplied with liquid CO2 by a set of pipes, this assembly being provided with a single common control valve. .
- the liquid CO2 in the pipes downstream of this valve can not be evacuated very quickly by the injection devices, and when the pressure falls below 5.18 bar approximately in the pipes, it turns into dry ice in these pipes which are thus obstructed. It is therefore impossible to resume the injection until the snow has disappeared by turning into gas by heating.
- the pipes connecting the valve to the injection devices are flexible, which allows disassembly, and therefore accelerates the restart of the system. This disassembly is however a relatively long and painful operation.
- Patent EP-744 578 describes an injection device making it possible to avoid the disadvantages caused by the incidents of capping under normal conditions of use.
- This device is such that the connection between the shut-off valve and the injection nozzle is calculated so that a plug possibly formed in said connection and said nozzle following a closure of the injection valve can be expelled to the chamber by the pressurized liquid during the reopening of the injection valve.
- the device does not have means to prevent plug formation, but the expulsion of this plug is possible from the restart, so that it is possible to proceed to a new injection to any time after the end of an earlier period of injection.
- this device can be plugged by the entry of the material to be cooled in the injection device, and therefore the use of this device is limited to the cooling of solid product.
- 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 into which is inserted a valve forced by a spring, said injection device comprising a through channel substantially parallel to said valve 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 seat of the valve.
- the spring is calibrated so that the valve can not slide without being subjected to a pressure of the cryogenic fluid at least equal to a threshold pressure.
- the device according to the invention it is impossible for the material contained in the enclosure can be introduced into the device and create fillings requiring disassembly and cleaning, whatever the physical state of this material.
- the device according to the invention is therefore suitable for cooling product both in liquid form, pasty, solid or granular.
- pasty product any product whose viscosity is between liquid and solid.
- the device may advantageously replace the cooling devices from the top of the tanks containing liquid or powdery products for which the systems of the prior art cooling down were not suitable.
- the cryogenic fluid used is liquid nitrogen or liquid CO2, especially 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 may comprise several transverse channels, one of whose ends opens at the seat of the valve.
- 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 subject to very large temperature differences. Indeed, the wall of the enclosure to which the device is attached is generally at room temperature, while the opposite portion of the device which receives the cryogenic fluid supply is at a temperature of -196 ° C. Icing phenomena on the external surface of the enclosure are therefore inevitable. There may therefore be sticking on the frosted wall of the enclosure of the material to be cooled. The icing points become hooked points of the product contained in the enclosure. These points become larger and end up closing the valve, no longer allowing the injection of cryogenic fluid.

- said lower element comprising:
- At least one supply channel whose one end is in connection with the supply system and the other end is in connection with an end of a through channel present in the central element, said through channel being substantially parallel to the axis of the valve, its other end opening at the seat of the valve,
- said through hole of the central portion having at its lower end an upper diameter such that in the mounting position, the setting spring is held against said shoulder in the central hole of larger diameter and in the central recess of the lower element.
- the various constituent elements are made of steel, preferably of steel stainless steel with the exception of the thermal bridge which is made of an insulating material.
- the various constituent elements are held together by means of a quick disassembly coupling or screw-type or bayonet type or the like.
- the device according to the invention must be able to be disassembled with a view in particular to calibrating the spring forcing the valve, or cleaning which is obligatory in the case of food products and which may be made necessary by abnormal operation or else by pollution. accidental.
- the device is connected to the cryogenic fluid supply via a flexible fluid conduit. This is to allow quick disassembly. Indeed, the flexible conduit does not have to be removed for cleaning.
- the cleaning is further facilitated by the maintenance of the various component parts using a rapid mechanical maintenance system ("quick" connection).
- a rapid mechanical maintenance system (“quick" connection).
- the device of the invention being intended to be used under pressure, means are provided so that only authorized personnel can disassemble the device.
- the component parts of the device are fixed to each other by means of tamperproof screws and an anti-whiplash cable is fixed on the one hand to the flexible hose, on the other hand on both sides of the hose. "quick" connection, on the lower part of the device and on the upper part of it. The withdrawal of the whiplash antibody cable is only possible by using a specific key whose use is reserved for authorized persons.
- the device according to the invention is fixed tangentially on the previously perforated wall of the enclosure.
- the enclosure is a kneader
- the devices at about 45 ° of the kneading arms in a sector between an angle of 0 ° (that is to say vertical) to 50 ° with respect to an angle of 90 ° (that is to say horizontal to the kneading arms) so that the cryogenic fluid is injected into the core of the material to be cooled.
- part of the cryogenic fluid is already converted 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 seat of the valve in the space between the seat and the support.
- the product can of course be in motion in the enclosure, which promotes heat exchange and thus the cooling of the contents.
- the device according to the invention is fixed on the lower part of the mixing tank.
