Definitions
- This invention relates to a method for carbonating and chilling a liquid, in which carbon dioxide is intro ⁇ quizd into the liquid below the surface thereof, and undissolved carbon dioxide in the liquid is compressed and chilled, to be recycled into the liquid below the surface thereof.
- the invention further concerns an apparatus for car ⁇ bonating and chilling a liquid, said apparatus comprising a closed vessel having an inlet and an outlet for the liquid; an inlet for carbon dioxide, which opens in the vessel below the surface of the liquid; an outlet for undissolved carbon dioxide in the liquid, which opens in the vessel above the surface of the liquid; a return con ⁇ duit connected between the carbon-dioxide outlet and the carbon-dioxide inlet; a compressor connected in the return conduit; and a chiller provided after the compressor for chilling the carbon dioxide compressed by the compressor.
- SE-C-8901970-7 discloses a method and an apparatus of this type. According to the SE specification, carbon dioxide is introduced under high pressure into the liquid below the surface via a throttling nozzle and is allowed to expand and dissolve
- the known method and the known apparatus are advantageous by not requiring any separate circuit for chilling the liquid in the vessel, it has, however, proved difficult to control the chilling of the liquid owing to uncontrolled ice formation tending to arise upon expansion of the carbon dioxide in the liquid when this consists of water.
- the object of the present invention is, therefore, to obviate the risk of uncontrolled ice formation without introducing any separate chilling circuit. According to the invention, this object is achieved by a method in which, prior to being introduced into the liquid, the carbon dioxide compressed by the compressor is expanded in an expansion conduit arranged in the liquid and connected between the return conduit and the inlet for carbon dioxide.
- this object is further achieved by an apparatus in which an expansion conduit is arranged inside the vessel and connected between the carbon-dioxide inlet and the return conduit to which it is connected by means of an expansion valve.
- the chilling of the liquid is essentially separated from the carbonation of the liquid, while at the same time no additional chilling circuit is required.
- the separation is due to the liquid carbon dioxide being evaporated in the expansion conduit and not in the liquid.
- the evaporated carbon dioxide expands in the expansion con ⁇ duit, while carbonation takes place after the carbon dioxide has left the expansion conduit in gaseous form.
- carbonated liquid is withdrawn from the vessel and replaced with non-carbonated liquid, the spent carbon dioxide naturally has to be replaced.
- this is suitably carried out by supplying also the replacement carbon dioxide to the liquid via the com ⁇ pressor, preferably by connecting a pressure tank for car ⁇ bon dioxide to an inlet opening above the surface of the liquid in the vessel.
- a pressure tank for car ⁇ bon dioxide to an inlet opening above the surface of the liquid in the vessel.
- the expansion conduit which should be made of a material of relatively good heat conductivity, suitably has a fairly large ratio of surface to volume.
- the expansion conduit may be a substantially helical tube of relatively small diameter.
- the expansion valve is disposed where the return conduit passes through a wall of the closed vessel, which is above the surface of the liquid to prevent any liquid from being drawn into the expansion valve.
- a closed vessel 1 consists of a pressure tank and has an inlet 2 for non-carbonated liquid, e.g. tap water, and an outlet 3 for carbonated liquid.
- non-carbonated liquid e.g. tap water
- An inlet 4 for carbon dioxide opens below the surface of the liquid in the vessel 1.
- the expansion valve 6 is disposed inside the vessel 1 adjacent to a wall thereof above the surface of the liquid.
- An outlet 7 for undissolved carbon dioxide in the liquid opens above the surface of the liquid in the vessel 1.
- the outlet 7 is connected to the inlet 4 by means of a return conduit 8 and the expansion conduit 5.
- the expansion valve 6 is disposed where the return conduit 8 passes through the wall of the vessel 1, giving the expan ⁇ sion conduit 5 a maximum length inside the vessel 1, while at the same time any liquid is prevented from reaching the expansion valve 6 since this is disposed above the level of the liquid.
- a compressor 9 is connected in the return conduit 8, and a chiller 10 is provided between the compressor 9 and the expansion valve 6 for chilling the carbon dioxide com ⁇ pressed by the compressor 9.
- the chiller 10 may, for instance, use water as chilling agent, e.g. tap water.
- a pressure tank 11 for carbon dioxide is connect ⁇ ed, e.g. via a pressure-reducing valve 13, to an inlet 12 opening above the surface of the liquid in the vessel 1, so that the pressure above the surface of the liquid in the vessel 1 is maintained essentially constant.
- a temperature sensor 14 disposed in the vessel 1 can switch the compressor 9 on and off.
- the temperature sensor 14 may be replaced with a sensor for sensing the thickness of the layer of ice normally formed in the shape of a cylinder round the expansion conduit 5 when the liquid consists of water.
- a level sensor 15 can be arranged in the vessel 1 for sensing the level of the liquid and control ⁇ ling a valve 16 regulating the supply of non-carbonated liquid via the inlet 2.
- the apparatus described above operates as follows.
- the carbon dioxide compressed, and thus heated, by the compressor 9 is chilled by the chiller 10, so as to condense to liquid form, and is evaporated when passing through the expansion valve 6.
- the temperature of the carbon dioxide is consider ⁇ ably reduced, and the expanding carbon dioxide can, when passing through the expansion conduit 5, absorb heat from the liquid in the vessel 1 to such an extent that a layer of ice is formed round the expansion conduit 5 in the vessel 1 when the liquid consists of water.
- the carbon dioxide whose temperature has thus been reduced passes freely out into the liquid in the vessel 1 through the outlet 4, thereby eliminating the risk of the outlet 4 freezing.
- the liquid in the vessel 1 is further chilled, albeit without any ice forma ⁇ tion, and a large amount of the carbon dioxide is dissolv ⁇ ed in the liquid while the carbon dioxide moves upwards through the liquid.
- the carbon dioxide not dissolved in the liquid reaches the outlet 7 and the compressor 9 via the return conduit 8.
- the carbon dioxide is recycled to the expansion conduit 5 for repeated chilling of the liquid in the vessel 1 and carbonation of the liquid upon discharge through the outlet 4.
- the degree of chilling of the liquid in the vessel 1 can be controlled by the sensor 14.
- the supply of replace ⁇ ment carbon dioxide from the pressure tank 11 can be auto ⁇ matically controlled by the pressure over the surface of the liquid in the vessel 1 by means of the pressure-reduc ⁇ ing valve 13 arranged in the conduit between the pressure tank 11 and the outlet 12.
- the level of the liquid in the vessel 1 may be automatically regulated by means of the valve 16 controlled by the level sensor 15.
- the supply of carbon dioxide can be regulated in some other way.
- the expansion conduit may be otherwise designed.
- a flavourant-adding device may be connected to a drain conduit connected to the outlet 3.
