Definitions
- the invention relates to an apparatus and a method for degassing substances, in particular emulsions obtained from pieces of frozen photographic emulsion.
- a method and a device are known for subjecting a liquid, with which a gas is simultaneously supplied, to a first degassing under vacuum while, in a second phase, this liquid is degassed further by means of a centrifugal rotor, to then accumulate in the form of an annular layer of liquid in a pumping element and then to be expelled by centrifugal forces against the vacuum prevailing in the system .
- a device for degassing liquids is known, a device in which the liquid is treated under vacuum in a centrifuge, this liquid spreading into a flowing film on the inner wall of the centrifuge rotor, to then be distributed into a fraction low in bubbles and a fraction rich in bubbles. So that the bubble-rich fraction can then be separated from the bubble-poor fraction, at the point where the liquid leaves the rotor while going outwards, a blade-shaped overflow element is provided on a on which side passes the liquid rich in bubbles, which is again introduced into the rotor to be treated there while, on the other side, the liquid is evacuated at a peripheral speed decreasing, this liquid having to be relatively poor in bubbles . In fact, compared to the liquid which is introduced into the rotor before degassing, the liquid discharged there is poorer in bubbles, but a sufficient absence of bubbles is not achieved.
- patent application FR-A-2 626 088 describes a process for obtaining a photographic composition capable of forming a layer on a support, said composition containing at least one emulsion with silver halides, as well as the additives finishing chemicals required. The process following this request consists in:
- stage (1) The constituents prepared separately in stage (1) can be kept cold separately, either after stage (1), or after stage (2) in the form of pieces, or at the same time after stage (1 ) and after step (2).
- the average volume of the pieces must not exceed 2 cm 3 , so as to ensure the homogeneity of the mixture in the subsequent solid state, and it is preferably less than 0.5 cm.
- the composition is liquefied by means of a device comprising for example an archimedean screw and a pump passing the solid composition in a heat exchanger.
- a deaeration device such as that described in application EP-A-58 353.
- EP-A -58,353 describes a method and an apparatus in which the liquid is spread in a thin film by subjecting it to a sudden depression.
- the pressure in absolute value to which the liquid film is subjected is of the order of 8100 Pa. But, under these pressure conditions, even if the bubble formation is reduced, the molten emulsion contains a large amount of air dissolved at a rate almost reaching saturation.
- the objects of the present invention are achieved by a deaeration process of a mixture of various constituents of an aqueous composition, in the form of solid pieces, characterized in that one applies to the mixture and before recasting of said mixture a pressure close to the water vapor pressure corresponding to the temperature of said mixture.
- the method according to the invention is implemented by means an apparatus for deaerating a mixture of various constituents of an aqueous composition, in the form of solid pieces, comprising:
- the device for deaerating the composition comprises a vacuum enclosure situated upstream from the recasting device and in which a pressure close to the vapor pressure is applied to the mixture of water corresponding to the temperature of the mixture, said enclosure comprising an inlet orifice through which the solid mixture coming from the feed hopper and entrained by said first conveyor device is introduced into said enclosure, and an outlet orifice through which the solid mixture is discharged from said enclosure and is entrained by means of said second conveying device towards the device for redesigning the mixture.
- the device shown in FIG. 1 mainly comprises a feed hopper 1, a deaeration device 4, conveyor devices 2 and 3 for transporting the mixture and a remelting device 5.
- the feed hopper (1) is fed with a mixture of various constituents of an aqueous composition, in the form of solid pieces.
- this mixture consists of a photographic composition with silver halides, capable of being applied on a support to form a layer.
- the process for obtaining these solid pieces consists, as described in patent application FR-A-2 626 088, of separately preparing the various constituents of the layer to be obtained, comprising at least one emulsion with silver halides, and solutions or dispersions containing one or more of the finishing additives and / or gelatin, to cool these constituents, to solidify them each in the solid state, to cut them into pieces, to mix in the cold, solid state, the constituents chosen according to the formulation of the desired layer.
- the feed hopper is provided at its base with a device with rotating blades (8) to prevent the formation of a bridge at the outlet of said hopper.
- the first device (2) transports the mixture from the feed hopper (1) to the deaeration device (4) which will be discussed in more detail later.
- the second ensures the transport of the mixture from the deaeration device (4) to a device for recasting the mixture (5) which will also be discussed in detail later.
- these conveying devices consist of a conventional Archimedes screw.
- These two Archi ⁇ tha screws (2), (3) are rotated by the respective motors (6) and (7) and terminate respectively by a sealed device (13) which can be, for example a pump of the MOINEAU type .
- a deaeration device consisting of a vacuum enclosure (4) between the two conveying devices and upstream of the device for recasting (5) of the mixture. Inside this enclosure, a pressure close to the water vapor pressure corresponding to the temperature of the mixture is applied to the mixture, said enclosure comprising an * inlet orifice through which the solid mixture coming from the feed hopper and driven by said first conveying device (2) is introduced into said vacuum enclosure (4) and an outlet orifice through which the solid mixture is evacuated from said enclosure and is driven by means of said second device conveying (3) to the mixture redesign device (5).
- the absolute pressure inside the depression chamber is between 1000 and 2000 Pa and preferably is between 1000 and 1500 Pa.
- the depression chamber (4) is, according to one embodiment, put in depression by means of a pump (9) connected to the enclosure by a tube (10).
- the enclosure (4) is provided with a stirring device (11) with rotary blades.
- the conveying device (3) and the stirring device (11) are rotatably mounted by means of bearings (not shown) allowing the enclosure (4) to be placed under vacuum.
- the role of this vacuum enclosure (4) is to minimize the amount of interstitial air (that is to say, between the pieces forming the mixture) and to decrease the amount of air dissolved in the composition it -even.
- the device for recasting the mixture (5) is located downstream of the vacuum enclosure and comprises a heat exchanger supplied, for example, by a circulation (14) of a thermal liquid.
- the emulsion is remelted at around 40 ° C and exits through the pipe (15).
- the heat exchanger is of the multitubular type. Its exchange surface is 3.2 m 2 .
- the heating fluid is water, the temperature of which is adjusted as a function of the flow rate of composition to be melted, but preferably less than 60 ° C. to ensure more regular reheating.
- the motor driving the conveying device (3) in rotation is controlled by the flow rate of the molten mixture leaving through the pipe (15).
- the motor driving the conveying device (2) in rotation can be controlled by the volume contained in the vacuum enclosure (4) by means of a probe (16). It is also possible to use an alarm device (17) indicating an insufficient filling level of the feed hopper (1).
- a photographic dispersion similar to that used for color paper is used.
- the viscosity of the composition once melted is of the order of 100 cp at 40 ° C.
- the speed of the Archimedes' screws is adjusted so as to obtain a dispersion rate once liquefied of
- the absolute pressure of enclosure 4 is adjusted to a value of 1500 Pa. When this pressure has been applied to enclosure 4, the rate of entrained air and the rate of dissolved oxygen which are respectively equal to 0.04% and 1.6 pp.
- Example 2 A gelatin broth containing 15% dry gelatin is used. The flow rate is 4 1 / min and the pressure 1500 Pa.
- the viscosity of the composition once melted is of the order of 70 cp at 40 ° C. Dissolved oxygen is equal to
- a gelatin broth containing 7% dry gelatin is used.
- the flow rate is 12 1 / min and the pressure between 1200 Pa and 1400 Pa.
- the viscosity of the composition once melted is of the order of 7 cp at 40 ° C.
- the dissolved oxygen is equal to 3.2 ppm at 40 ° C and the entrained air rate at 0.01%.
- Example 3 The same composition is used as that used in Example 3 but this time no vacuum is applied inside the enclosure 4.
- the dissolved oxygen is equal to 6.3 ppm at 40 ° C (saturation) and the entrained air rate is 5%.
