Definitions
- the present invention relates to a method and u device for the distribution of liquids such as liqui from food and in particular from refrigerated drinks or not, in which a concentrated liquid is diluted by means of a diluent liquid, in particular water.
- the invention applies in particular to the distribution of refrigerated drinks from concentrates, such as for example drinks prepared from natural fruit juice concentrates, for example oranges, with or without pulp, crushed or unground .
- the devices or apparatuses of this type currently known are intended to automatically ensure the dilution of a concentrated liquid product, viscous or not, with or without pulp, in water, in general water refreshed and, in general, to deliver doses of the product thus diluted, for example to the glass or to the cup.
- US Patent 2,920,579 describes a device in which the fruit concentrate is brought directly into the axis of a venturi by an adjustable injector 44 opening into a venturi nozzle. It is clear that such a device has been provided to try to adjust, by axial displacements at the level of the venturi, and this in an extremely fine manner, the flow of concentrate. This implies that the depression caused is not substantially constant and varies, notarr_r nt depending on the level of concentrate in the refrigerated container of concentrate 16.
- this device is complex and comprises a complicated venturi made up of several assemblable parts, to namely, in particular, the central injector, the part forming a nozzle and distribution duct, a water inlet, a blocking part 49 as well as seals and blocking means.
- these different means are necessary because of the principle of operation and of adjustment required. Of course, these parts are difficult to disassemble and difficult to wash.
- the throttling of the venturi is provided to prevent the entry of air coming from the opening 21 at the injector, which means that the duct 20 receives air through its mouth and that in this conduit the liquid is not sheltered from the air and therefore from fermentation.
- French patent 1,392,840 describes a device in which there is air inside the pressure-reducing member before the start of operation.
- German patent 3,234,957 describes a device which is intended to operate at very high pressure and not at pressure such as that delivered by an ordinary pipe. To this end, it includes a pump for increasing the pressure. It recommends, in the case of concentrates containing pulp, to introduce air into the device, so that it probably succeeds in ensuring a certain homogeneity of concentration only by means of a very strong pressure. Even in the case where air is not admitted into the device, the air enters the delivery tube.
- This device is obviously very complex and requires an additional valve as well as regulating means. In addition, it is cumbersome, the pressure-reducing member cannot be located above the container.
- the present invention proposes to remedy these drawbacks and to provide a method and a device for dispensing liquids such as food liquids and especially beverages, making it possible to dilute, to a given concentration and with great precision, a liquid concentrate which can be indifferently viscous or non-viscous, with or without crushed pulp or not and, if necessary, to deliver the diluted product in exact doses, and this by using simple means, inexpensive and little subject to breakdowns.
- Another objective of the invention is thus to make it possible to obtain an extremely homogeneous diluted product.
- Another objective of the invention is to produce a device which does not use complex mechanical means in contact with the concentrate or the diluting liquid.
- Another objective of the invention is to avoid or considerably limit the phenomena of oxidation or fermentation of the liquids contained and thus to conserve the organoleptic properties of the food liquid delivered, and this in particular for products very sensitive to oxidation and fermentation.
- Yet another objective of the invention is to provide a device which is extremely easy and easy to clean, allowing rapid disassembly.
- Yet another objective of the invention is, in the frequent case where the diluent liquid is drinking water, to use the pressure from the drinking water network which supplies the device as an energy source.
- the subject of the invention is a process for the distribution of liquids such as food liquids and in particular drinks, in which a liquid concentrate is diluted to a diluting liquid, such as in particular water, by circulating the diluent liquid through a pressure reducing device at a determined rate so as to create a vacuum and the liquid concentrate is brought inside the pressure reducing device into the flow of diluting liquid, characterized in that the diluting liquid. at usual pressure, circulates so as to create a constant depres ⁇ sion large enough to bring the liquid concentrate into the flow of diluent liquid via a calibrated passage, the flow rate ' drawn in from concentrate not being sensitive significantly to variations in level in the concentrated container that contains it.
- the liquid concentrate is fed with the depressant organ by the simple suction effect of the depressor organ, or possibly by additionally using the gravity of the concentrated liquid.
- the pressure-reducing member continues with a distribution pipe which may possibly facilitate or improve the homogenization of the product to be distributed, and according to an advantageous characteristic of the method according to the invention, it is maintained between two successive operations dispensing, the liquid product in said pipe preventing any entry of air, and preferably maintaining the volume of the pipe at a very low value compared to the volume of doses which can be dispensed.
- this ratio can be between 0.5 and 2% of the dose volume, the latter being able to range up to 20 cl and more.
- Maintaining the liquid product in said pipe can be carried out preferably by simple effect of the surface tensions, for example by capillarity, and / or by the geometrical arrangement of the pipe, but other means can also be used, in particular gravity , the use of check valves, especially on the concentrate etc ...
- said pipe may consist of, or comprise directly downstream of the pressure-reducing member, a homogenization pipe preferably of small diameter with a length / diameter ratio preferably greater than 10.
- the diluent liquid is potable water
- the method according to the invention makes it possible to obtain a diluent / concentrated volume ratio of between 2 and 100 and more.
- the flow rates and passage sections are preferably designed so as to allow a flow speed of the diluted product of the order of 2 to 6 m / s.
- the invention also relates to a device for the implementation of the method and comprising a source of diluent liquid, in particular the drinking water network regulated by a regulator, a source of concentrated product, a pressure-reducing organ for diluting the concentrated product in the diluent liquid, characterized in that it comprises a depressogenic organ of simple shape inside which the liquid concentrate is brought in via a passage calibrated to provoke. No effect of suction of the liquid concentrate according to a constant depression such that the concentrate suction flow is not significantly sensitive to changes O * th level of the concentrate container.
- the pressure-reducing element may consist of a single chamber supplied with diluent liquid through a calibrated nozzle to create in the chamber a stable depression sufficient to suck the concentrate at a stable flow rate.
- the pressure-reducing member continues, in the axis of the nozzle or of the diluent liquid flow, by a conduit of small internal volume and preferably of short length through which the final product is distributed, conduit preferably leading to a spout.
- This duct can advantageously be a duct having a length / diameter ratio greater than 10.
- the source of concentrated product is located under the pressure-reducing member and the tubing then plunges into the source of concentrated liquid which is progressively sucked in, anti-reflux means such as for example a ball valve, being arranged in the tubing, for example * at the level of the pressure-reducing organ or, better, at the lower end of the tubing immersed in the source of liquid concentrate.
- anti-reflux means such as for example a ball valve
- the source of concentrated product which can then consist of a simple container, can be, if desired, suitably refrigerated and it is advantageous to use these refrigeration means to cool the flow of diluent liquid.
- the distribution conduit can play the role of homogenization conduit and is. preferably, designed in such a way that at the end of the dispensing, it remains filled with liquid, as well as, if necessary, the spout which extends it, the internal volume of these elements retaining the liquid preferably by capillarity , although other means may be provided that Tejs valve, inclination of the conduit 'allowing liquid to remain by gravity, etc ...
- the entire device according to the invention is therefore always filled with liquid, which opposes the penetration of air and avoids or considerably reduces the phenomena of oxidation and / or fermentation. .
- the material or materials in contact with the final product, the diluent liquid and the concentrated liquid are preferably opaque and produced with an excellent surface condition.
- the adjustment and / or adaptation of the concentration of the final product can be carried out by acting on the flow rate of the diluent liquid in the pressure-reducing element, but preferably this adjustment is carried out using interchangeable pressure-reducing elements of suitable dimensions or, in a same pressure-reducing organ, using calibrated nozzles and / or calibrated passages of different diameters to introduce the diluent liquid and / or the concentrate.
- FIG. 1 represents a schematic view, in sagittal section, of a device according to the invention
- FIG. 2 represents, on an enlarged scale, the pressure-reducing member and the distribution duct with the pouring spout.
- a device for dispensing doses of orange juice from frozen concentrate comprises, in a suitable camber 1 covered by a cover 2 presenting a part 2a in cantilever, a heat-insulated enclosure 3 inside which is arranged a means of refrigeration
- 3_0 ration such as a coil (not shown) to maintain a temperature of 2 to 4 ° C.
- a container 4 containing the concentrate of frozen orange juice which, after a certain time, gets to the temperature prevailing in the enclosure 3.
- a metal or plastic part 6 of generally parallelepipedal shape and the shape of which is best seen in FIG. 2. This part comprises a depression chamber -
- a second chamber 12 this time vertical, opens into the front part of the chamber 7 through a calibrated orifice 13.
- the internal dimensions can be as follows:
- 35 - chamber 12 length 18 mm, diameter 12.2 mm
- - calibrated orifice 13 diameter 4 mm, thickness 2 mm.
- a vertical pipe 14 which extends to the vicinity of the bottom of the container 4 where there is a narrowing with a ball 1 forming a non-return valve, preventing in the state of rest l concentrate of liquid contained in the tube 14 to descend to the container 4.
- the connection of the pipe 14 in the chamber 12 is effected in a sealed manner, for example by means of an O-ring.
- the dimensions are as follows: - pipe 14: length 200 mm, diameter 10 mm
- an injection nozzle 16 containing a calibrated orifice 17 in the axis of the chamber and of the conduit 8 is in place, at a location such that the useful volume of the chamber 7 disposed between the nozzle and the conduit 8 has an axial length of 4 mm, without taking account of the conical end of the chamber 7.
- the chamber 7 is connected to a pipe 18 of which only the initial part is shown on the Figure 1.
- a solenoid valve 19 is mounted on the canalization 18 and is controlled by a button-ression (not shown) or another control device, to open the passage for the determined duration which, taking into account the characteristic dimensions of the apparatus, makes it possible to deliver a very precise dose of product and in this case orange juice ready for consumption, for example in cups.
- the solenoid valve 9 can be replaced by any other control means, timed or not.
- the device thus produced is extremely simple and has no moving parts.
- the whole ble of these elements can be made interchangeably and the various passages and pipes of the part 6 are devoid of blind spots and have a smooth internal wall of good quality.
- These different 5 parts, namely part 6 with the pouring spout 11, preferably not removable, the pipe 14 and the injection nozzle 16 can be very easily dismantled and cleaned and this daily.
- Adjusting the concentration of the distri- j _0 mist dose is ensured each time using a nozzle 16 having an appropriate diameter of orifice 17 and by keeping this nozzle in place in the chamber 7.
- the doses distributed present a constancy of sufficient concentration to be completely imperceptible to the taste and to be in harmony with the regulations in force, and this thanks to the presence of the calibrated orifice 13 with a high pressure drop
- Example 1 Preparation of an orange juice with a natural frozen concentrate with unmilled pulp. This concentrate must be stored at a temperature less than or equal to -18 ° and in use it must be reheated to a temperature around 0 ° C. It is a product which does not have very precise characteristics and which needs to be diluted for one part of concentrate with three parts of water for the reconstitution of the original orange juice, which has a BRIX degree of 10.2.
- the viscosity of the concentrate is 290 centipoise at 4 ° C and 310 centipoise at 2 ° C.
- the temperature of the concentrate varied from 2 to 4 ° C during the test.
- a nozzle 16 was used having an ori ⁇ fice diameter 17 of 1.9 mm and the water pressure at the end of the nozzle was reduced to 0.8 kg / cm 2 effective. During all the tests, a fruit juice having a BRIX degree of 10.1 ⁇ 2% was obtained, while the relative variation in the level of concentrate in the container 4 was 15 cm. This variation in BRIX degree cannot be detected by taste.
- Example 2
- the viscosity of the concentrate is 445 centipoise at 5.5 ° C and 475 centipoise at 3.5 ° C.
- the suction pipe is modified in that the ball valve has a diameter of 5.5 mm instead of 8 mm and in that the hole in the seat of the ball has been reduced to 3 mm.
- the nozzle has an orifice diameter 17 of 2 mm, the water pressure being 0.850 kg / cm 2 .
- the fruit juice reconstituted by the process according to the invention has a BRIX degree of 10.6 + 3%.
