Definitions

  • the invention relates to an in-line fumigation dispenser impregnator for displacing a non-gas or low-gas beverage pre-product liquid with gas according to the preamble of claim 1.
  • the invention further relates to a dispensing system with inline fumigation according to the preamble of claim 23.
  • Impregnation in the context of the invention is the dissolution of gases in liquids, ie the impregnation of liquids with gases, as it is used in absorption columns in large-scale plants.
  • a gas to be absorbed in a liquid is passed in a column from bottom to top in countercurrent to the liquid flowing from top to bottom through the column packed with a porous ceramic material.
  • beverage dispenser impregnators are, however, used to impregnate beverage precursors with gases in dispensing systems or to dissolve gases in the beverage precursors and so produce ready to drink drinks only in the dispensing system.
  • beverage precursors to be impregnated are lemonades, (-sirupe) and, in particular, a low-carbon or low-acid beer precursor.
  • suitable impregnating gases are, in particular, carbonic acid (more precisely: CO 2 ) and nitrogen (more precisely N 2 ), for example to produce a bubbly lemonade and in particular a carbonated beer.
  • carbon dioxide or “carbonated” is common in beverages, but more specifically, carbon dioxide (CO 2 ) is added, which binds for the most part only physically in the liquid and no chemical reaction to carbonic acid (H 2 CO 3 ) received.
  • Efficient mass transfer systems must therefore have a large surface area at which the mass transfer can take place, provide great turbulence for the shortest possible transport routes, and provide high pressure and low temperatures in order to achieve the most efficient and rapid mass transfer.
  • bubble-forming systems such as stirring systems, loop reactors or injection systems
  • high equipment costs pressure vessel, pressure pump, cooling system
  • high operating costs have in the tap beverage beverage enforced with carbonic carbonators or impregnators of the type described.
  • impregnators are often used in inline fumigation dispensers in which the beverage precursor is conventionally sucked out of a bag with piston pumps from a tank and more recently also with diaphragm pumps, so that the impregnator is exposed on the input side to the pressure surges of the piston pump and no constant fluid pressure can be achieved.
  • the volume flow which enters the mixing cell per unit time, depends essentially on the dispensing speed with which the tap taps the drink. As the dispensing speed changes, the pressure drop from the gas supply side to the mixing cell is also changed, so that the opening degree of the gas supply and the liquid supply fluctuate although the external pressure is set to a fixed value. As a result, the volume flows entering the mixing cell also change, so that the gas-liquid mixing ratio can deviate from the optimum for dissolving the gas in the liquid at the respective pressure in the mixing cell.
  • a beverage is conveyed from a beverage container via a beverage supply line to a usually higher-lying dispensing tap.
  • the beverage supply line consists of a dispensing line
  • in dispensing systems with inline fumigation or on-side Druckbegasungsbran can also be arranged in the beverage supply line one or more impregnators, with a beverage precursor is enriched example with carbon dioxide.
  • mixing valves for syrup with an inline-fumigated water can also be in the beverage supply line and a buffer container in which the water is gassed under a carbon dioxide atmosphere.
  • a certain delivery pressure is necessary.
  • this is provided for example via a compressed gas (eg carbon dioxide), with the pressure of a beverage keg or a beverage container is applied, so that the drink over the dispensing line is pushed up to the tap.
  • a compressed gas eg carbon dioxide
  • Impregnator is provided to a low-carbon or -lose beverage pre-product in the dispensing system with carbonic acid or the like.
  • a displaceable throttle body is arranged in the feed line of the tap, the position of the tap can adjust via an adjusting screw so that the throttle body releases an annular gap of a desired thickness and thus change the resistance and can be adapted to the desired conditions.
  • the taper adjusts the tap to a desired flow rate, for example, according to whether it has large vessels such as e.g. 1l-Millerkrüge or small vessels, such as 0.25l Colagläser wants to fill and after the liquid to be tapped, for example, light beer in contrast to wheat beer.
  • US patents US Pat. No. 6,712,342 B2 and US 6,138,995 disclose beverage dispensers in which hollow fiber membranes or bundles are provided. Therein, hydrophobic hollow fibers serving as impregnating bodies are installed, through which CO2 flows and are bathed by the liquid to be impregnated. In this case, only the gas can pass through the walls of the hollow fibers and thereby impregnates the liquid on the other wall side.
  • Another dispenser-impregnator for example, in the DE 198 51 360 A1 proposed. It is a Rohrsiebkarbonator, in which a plurality of mixing screens are lined up in a mixing cell designed as a tube to the gas and liquid supply can be connected. The mixing screens in their entirety provide the desired large surface area at which the mass transfer can take place upon dissolution of the carbonic acid in the beverage precursor.
  • a Rohrsiebkarbonator is also the patent application DE 100 55 137 A1 refer to.
  • Rohrsiebkarbonatoren are not only relatively expensive in terms of material costs, but also in terms of the corresponding complex assembly due to the high number of metal screens.
  • an impregnating body is arranged in a mixing cell of the in-line dispensing machine impregnator, into which a gas inlet and a liquid inlet discharges and from which an outflow for the liquid-gas mixture leads, so that the passage of the liquid and of the gas through the Mixing cell forcibly must be carried through the impregnating through, wherein the impregnating body consists of a porous material, that is a porous solid is.
  • the porous or having pores Solid body can be made of any pore-containing material with a large surface, such as sintered materials, woven, knitted. Braided or felt solids, or sponge or foamed materials or the like.
  • the material used for the impregnating body are all of the above-mentioned materials.
  • the or one of the impregnating body is made of a sponge made of foamed material or foam existing body, have many advantages, since these materials have a high porosity adjustable depending on the material, relatively have a large number of pores and average pore size and thus large phase boundaries with low flow resistance and sufficient resistance to material rinsing.
  • the foam it is particularly advantageous for the foam to have the cell structure of a reticulated filter foam which is almost 100% open-celled. Due to the reticulation, the cell membranes are almost completely removed, leaving only one framework. This ensures a very low flow resistance. The phase boundary surfaces are therefore no longer located at completely surrounded by material walls pores, but only enclosed by a scaffold material, otherwise open-walled cells.
  • the foam is advantageously compressed in the carbonator, in particular from originally 150 mm to 80 mm in length.
  • the foam impregnation body is compacted and the number of cells increases to about 170,000 cells / cm 3 .
  • the impregnation body is advantageously designed as a disk filling the diameter of the mixing tube, so that the liquid, but also the gas, must forcibly flow through the impregnation body and dissolve on the large surface at the pores of the solid. It is advantageous that this solid can be easily introduced into the mixing cell, but also can be easily removed from it again, so that on the one hand cost-effective production and on the other hand maintenance of the impregnator at the predetermined by the hygiene rules intervals is easily possible. A flushing of bulk material is thus effectively avoided without the high cost and the constructive and assembly-related effort as in a Rohrsiebkarbonator incurred.
  • the impregnation body with a socket - for example made of plastic - and thus to form a diameter of a mixing cell designed as a mixing tube filling impregnating cartridge.
  • appropriate fixing means may be provided, such as a perforated plate or a grid which holds the impregnating body in position and with which the impregnating body is optionally compressed.
  • a further advantageous development relates to a high-frequency or ultrasonic vibration device which acts on the interior of the mixing cell and thus serves as additional impregnation device or as impregnation support device.
  • the vibration device could, for example, be attached to the wall of the mixing cell, have ultrasound generators distributed over the entire circumference of the mixing cell and / or an ultrasound unit arranged in the mixing cell. Due to the vibrations generated by high-frequency vibration and the cavitation caused thereby high turbulence and thus short transport routes are achieved in the mixing cell in the mixing cell. It is particularly advantageous in this case for the ultrasound application to take place under the pressure prevailing in the mixing cell of the carbonator or impregnator (for example 3 to 5 bar) and when the medium is flowing through.
  • a method for dissolving gas in a liquid by means of ultrasound is in the European patent specification EP 0 661 090 B1 described.
  • the invention is not limited to an impregnator with a impregnating body. Rather, several impregnating bodies can be arranged in series in the mixing cell. In this case, each or some of the impregnating body may consist of different materials, so that the mixing properties of the impregnator can be better matched to the particular liquid, gas or desired starting composition.
  • a the mixing cell gas and liquid supply side against the environment sealing head piece is provided, which is provided with a connection for a liquid supply line and a connection for a gas supply line.
  • the impregnator can thus be easily installed in existing systems.
  • the impregnator is preferably produced as a one-piece end product, for example as a one-piece injection-molded component with a welded-in impregnation body.
  • the impregnator can also be constructed so that it can be broken down into its individual parts and cleaned, with a simple replacement of the impregnation or the body is possible.
  • the impregnator total except for the impregnating or the impregnating
  • at least the housing of the mixing cell made of a plastic which does not swell and can be formed with sufficiently accurate tolerances.
  • the gas outlet can be provided, for example, on a mixing tube screwed on the inside of the head piece pipe stub.
  • a second gas supply line connection may be provided on the mixing cell. It would also be conceivable, for this purpose, to connect a plurality of impregnators in series in such a way that the outflow of a preceding impregnator is connected to the liquid feed of a subsequent impregnator so as to create an impregnation plant for mixing a liquid with a plurality of gases.
  • Such impregnators with multiple gas connections can be advantageously used to offset a non-carbonated or only slightly CO 2 -containing beer precursor with CO 2 and nitrogen. Nitrogen is added to beers - at least in non-banned countries - for better foam durability, whereas CO 2 beer precursors must be added, which are not or only slightly CO 2 -containing.
  • impregnator according to the invention is obtained when adding a beverage precursor with aromas, since aromas or fragrances are often present in gaseous form.
  • This use is particularly suitable for substances that are not long lasting when mixed or in low concentrations and freshly prepared on an ongoing basis.
  • an apple juice with a cherry flavor could be added.
  • the impregnators according to the invention which have only one gas inlet, can also be used with particular advantage to displace a non-bubbling or weakly bubbling, or non-weak or weakly CO 2 -containing beer precursor with Co 2 .
  • they can also be used to treat beer or beer precursor with nitrogen.
  • a gas inlet valve and a liquid inlet valve are further provided, which are adapted to enable and close the gas and liquid inlet of the impregnator according to the size of a pressure gradient from the inlet side to the mixing point, wherein the gas inlet valve has a arranged in a gas inlet channel Gaseinlassschuiteelement, and Liquid inlet valve disposed in a liquid inlet passage liquid inlet closing element, and wherein the gas inlet closing element and the liquid inlet closing element are coupled together so that the gas inlet valve releases the gas inlet depending on a self-adjusting opening degree of the liquid inlet to a predetermined opening degree.
  • the coupling according to the invention of the opening degree of the gas inlet with the degree of opening of the liquid inlet it is thus possible to set a mixing ratio suitable for the impregnation process in the mixing cell interior for different dispensing speeds.
  • the coupling can be linear or degressive or progressive with the pressure rising. If the liquid inlet opens wide, the gas inlet also opens correspondingly wide so that, for example, the necessary carbonic acid flows in to impregnate a non-carbonated beer precursor. On the other hand, if the opening degree of the liquid inlet is reduced, the opening degree of the gas inlet also decreases correspondingly, so that, in turn, a mixing ratio of gas and liquid suitable for the impregnation operation in the mixing cell is established.
  • the liquid inlet closing element reduces the opening degree of the liquid inlet and thus the gas inlet closing element coupled thereto decreases the opening degree of the gas inlet accordingly.
  • the gas inlet closing element the opening degree either in the same ratio, or a suitable for the respective impregnation process (mixing ratio of the pressure) following the law, as predetermined by the liquid inlet closing element.
  • the liquid inlet valve will release the liquid inlet to a certain degree, depending on the existing at any time pressure drop from the liquid inlet to the mixing cell the coupling of the gas inlet valve and the gas inlet is opened accordingly wide.
  • the liquid inlet closing element is biased towards the liquid inlet side and integrally connected to the gas inlet closing element, so that a displacement of the liquid inlet closing element is transmitted to the gas inlet closing element.
  • the unit thus formed may be formed in the manner of a piston valve, when the mixing cell head or the head piece of the impregnator is constructed like a T-piece, i. when liquid inlet and gas inlet are aligned. It is thus possible in a structurally simple manner to establish the inflowing liquid mass flow as well as the incoming gas mass flow as a function of the pressure gradient from the liquid inlet side to the mixing cell.
  • an electrical coupling of the closing elements could be provided.
  • a piston slide unit consisting of the gas inlet closing element and the liquid inlet closing element in the manner of a directional control valve could also be used in a mixing head in which two inlet passages running in parallel lead into the mixing cell interior.
  • a closed position could be provided, in which the spool seals both the gas inlet channel, and the liquid inlet channel, and an open position in which the spool is pushed with one or more openings penetrating it both in front of the liquid and gas inlet opening, so that the respective inlet is released.

  • a displacement towards the liquid inlet closes both the gas inlet and the liquid inlet.
  • this response to the pressure drop from the liquid inlet to the mixing cell could be accomplished by having the gas inlet closure member be a conically expanding flask adjacent to the gas feed side, which is in a likewise tapered gas inlet channel section and connected to the liquid inlet closure member via a spool valve section ,
