Abstract

The invention relates to a method which uses a drop in pressure, which develops in the still water circuit when at least one dispensing point is connected to the still water circuit and is drawn off from the supply of liquids of said still water circuit. At this point, the drop in pressure in the supply network is used in order to supply at least one inline carbonator with liquid for the carbonation thereof, preferably tap water with CO2, during the dispensing step.

Description

Method and arrangement ■ for carbonating a liquid

The invention shows a method by the DruckabfeU that arises in the Stillwasser- cycle when at least one tap is connected to the Stillwasser- cycle and is tapped from the supply of liquids of the Stillwasser- cycle. At this moment of pressure drop, the pressure drop in the mains network is used to supply at least one in-line carbonator with liquids to carbonize during the tapping process, preferably Co ² with tap water.

The Leitwasserguhr pressure is increased by at least one fluid pressure increase pump and is pressed at high pressure in a so-called Karbonatorkessel or pot. Addition of Co ² can carbonize. However, this always takes place by increasing the pressure inside the carbonator shell. So you have to increase the fluid pressure. Such a type of carbonization is mainly used in the dispensing industry for water dispensers and post-mix systems.

In this way, to carbonize via a carbonator, mainly applied models, such as counter units with intregated cooling for tap water and syrup refrigeration, undercounter appliances with cooling for tap water and syrups, and circulating carbonator units.

The so-called circulatory carbonators are also available to allow at least one, in technical terms, python to be used. The so-called Pyton is nothing else, for example: syrup lines and gas line and still water line and also carbonation line, bundled and isolated from the carbonator to connect to the tap. In such an application, a carbonator kettle, tap water and Co ^{2 are} carbonated via a booster pump within the boiler and this carbonated water is circulated. This carbonated water, with the help of a circulation pump, always in the direction of the taps, in a circuit, kept in motion and runs over and over again a cooling for liquids to keep the carbonated water at an ideal tapping temperature to produce post-mix drinks , In the prior art, in the aforementioned principle, two pumps are needed, a Druckhδhungspumpe to carbonize, and a circulation pump to keep carbonated water in circulation. One of these pumps can also run the still water cycle to recycle non-enriched tap water around this still water circuit, which is also used primarily to cool syrup or used to mix carbonated water with still water. All the above mentioned pipes are bundled and insulated.

The invention saves at least one pump, in the aforementioned method or other methods and also the circulation lines for carbonated liquid, fall away. Because the invention uses the pressure drop to carbonize the tapping process, which inevitably occurs.

In the still water cycle of chilled or uncooled water or mineral water to the or the still water circuits also at the same time to refill with the amount of purged liquids again the inevitable pressure drop in the still water lines is used or the stillwater circuits, the are connected to one or more circulation pumps to the still water to be pumped in the circuit, has at least one supply connection to one or more main supply for liquids, preferably tap or mineral water. If the pressure drop takes place in the circuit, at least one pump, fresh water can flow or sucked at least one pump and be prompted by the pressure increase of the pump in the flow line in the direction of tap or points to, for example: the stillwater circuit for the Use cooling of syrups and carbonation to ensure that the pressure drop within the circuit of the circulation lines, which is preferably introduced in a preferably, for example: Python, is kept constant in order to have a constant pressure drop controlled by the The invention makes use of the following: The fluid pressure in the circulation line is kept constant. This may, but is not strictly necessary, be set directly at the pump. For example, if the stillwater circuit, which is always pressed or sucked down by a so-called cyclone, this refers, for example, to the liquid, 6 bar fluid pressure, the pressure drop inevitably arises because water is an inertial mass and inevitably the lower Resistance follows, which is when tapping in the direction of tap or taps, is used so that the liquid in the direction of inline carbonator or in general in any device that can be 'used for carbonization''liquid is supplied. This liquid is simultaneously mixed with gas, preferably Co ² or enriched or mixed and can then simultaneously flow through the preferred in-line carbonator and get to the one or more taps to preferably produce and tap non-alcoholic soft drinks. This is commonly known as the post-mix method. As long as is tapped, can be carbonated over the or the preferred: in-line Karbopnator in the flow process, because in the reverse bend, which is the flow line or lines connected to the Return line or lines, in turn, with the or the Kreislauφumpen preferred: positive displacement pump, is connected and provided with at least one additional outlet to preferably: inline carbonator or carbonators with liquids to supply.

When the tapping process is finished, carbonation is no longer possible. Because up to the taps, a pressure equalization has taken place and now the liquid is circulated only in the still water cycle. Also, the new fluid supply then rests from the main water supply, towards the pump. At least one backflow preventer is inserted or interposed in the return line, in order to force downstream water from the main supply to flow in the direction of the pump, in order to guarantee the pump suction flow direction. Also, at least one pressure regulator should be provided between the main supply line for the liquid and the pump, which if possible also cleans the liquids before a filter system. The aforesaid still water cycle can also be used, for example, to supply two or more preferred in-line carbonators with liquids to utilize the pressure drop within the lines to carbonize.

The following is a detailed description of the invention.

And schematic drawing of the figures: 1 and 2

Description:

In order to initiate at least one carbonation process which is via pressure drop within at least one liquid circulation system (9) (10) cooled or uncooled with preferably tap water, the invention will be described as follows.

The liquid main supply (13) has at least one connection possibility for a pressure limiter (21) in the line (16), at least one - Rückflussbegrenzer (12) can be intregiert. The line (16) is connected to the line (9), in which at least one backflow preventer (12) is mounted in the flow direction to open the pump (15). The lines (9) (16) are at the connection possibility (14) of the pump (15) there to use ^ to the liquid supply to the pump (15) and the still water circuit (9) (10) consisting of the following components: Reverse bend (7) with at least one outlet (8) of the return line (9) with intregierten backflow preventer (12) with connection option (16) and the intregierten backflow preventer (12) is intregiert on the supply line (16).

The pump connection (14) is connected to the line (16) and the return line (9),

The pump connection (17) which serves for the circuit (9) (10) and which also serves to fill the circuit cooling coil (23) for liquids in order to connect the connections (17) to the line (23), preferably screwed (not shown in the drawing).

The coolant line (23) is used for connection via the connection possibility (22) to the connection (10) via the connection possibilities (11), the still water circuit is produced which is guaranteed when the tap points (1) are not open. Via the outlet (8), the liquid supply via the port (6) of the Iriline carbonator (5) take place to pressure drop, which takes place when at least one tap (l) is opened. At this moment, triggered by the pressure drop within the liquid circuit (9) (10) the sluggish amount of liquid on the reverse bend (7) reach the outlet (8) via the connection possibility (6) in the carbonator (5). At the same moment, preferably Co ² gas can flow via the connection (20) into the inline carbonator (5) and leave the preferably inline carbonator via the outlet (4). The liquid, preferably tap water offset with preferably Co ² is in the flow through the carbonator (5) the fluids and Co ² carbonized. This carbonated liquid is then passed on via the outlet (4) preferably via at least one distributor (3) which takes over the distribution of carbonated liquids via at least one line (2) to at least one tap (1) which the removal of carbonated liquids makes possible. The gas supply (20) is connected to at least one main gas supply. (Not pictured) To cool the liquids, state of the art is applied (not pictured)

The pump (15) is preferably a Trennschieber- positive displacement pump, the deri constructed fluid pressure via the outlet (17) further in the direction of cooling (23) continues to give and forwards in the direction preferably inline carbonator (5) and at least one tap (1) , When tapping creates a pressure drop within the StiHwasserkreislaufes (9) (10) passing at this moment on the main liquid supply (13) via the pressure regulator (21) pass through the backflow preventer (12) pass through at least one filter system. (Not pictured) Then the liquid flows via the line (16) in the direction of the pump (15) via the connection (14) of the pump (15). By this process, the still water circuit (9) (10) is always refilled with the amount of liquid that is removed during the tapping to the liquids, preferably tap water, cooled to at least one tapping point (1) to provide. Pumps the pump (15) in the direction of cooling (23) and builds up the pressure in the direction. Thus, the still water circuit (9) (10) can be easily filled, the invention uses the slide valve pumps (15) can be self-priming. This, in turn, guarantees that the still water circuit (9) (10) is filled because it is not always possible to find such a high fluid pressure on site as to guarantee the liquid main supply (13) with fluid of the circuit (9) (10) is because to fill the circuit (9) (10) again with liquids. It is advantageous to use a self-priming pump (15). It is also possible to use a pump to refill the liquid for supplying the circuit (9) (10) with an additional liquid pressure pump. (Not shown in the picture) If cooling (18) is required to cool liquids, the cooling (18) may also be stationed at a location other than the location of the carbonisation (5) or tap (l) or main connection (13) , (Not pictured)

The still water circuit (9) (10) can also be used for cooling beverage additives. (Not pictured)

The Stülwasserkreislaufleitungen (9) (10) and reversal sheets (7) (not shown pictorially) are bundled with beverage additive lines and isolated in at least one so-called Pyton introduced or similar methods apply. (Not shown) This would have the advantage that in a simple way also to cool the beverage supplements for post-mix drinks. The beverage additives, which can be transported independently in lines separately to at least one tapping point (1) and pre-cooled (not pictured)

FIG. 2 shows the same principle as FIG. 1, with the difference that two preferably in-line carbonators (5) are supplied by a still water circuit (9) (10) of cooled or uncooled liquid. Insulated into at least one bundle, more such as a stillwater circuit (9) (10) can be introduced around the stillwater circuits (9) (10) including the preferred in-line carbonator (5) or carbonators (5) with the components (3 ) Distributor (3) and the carbonated liquid outlet (4) and the lines (2) and the taps (2) or tapping point (1) preferably post-mix taps (1) to clean, there is one or more connections to separate the necessary For flushing with preferably tap water, the main supply (13) for liquids is used and withdrawn via the tapping point (1) or the taps (1) until the rinsing process has been carried out ) or pump (15), at least one additional still water circuit (9) (10) can be used for the purpose of accompanying refrigeration cycle. (BilcUich not shown)

To any pressure fluctuations that can occur when using pumps (15) (technical term pressure peak) of pumps (15) or Leituήgswassernetz (13), it is advantageous that one uses a pressure control valve for gases and liquids. This prevents if, for example, the fluid pressure increases. At this moment, it may happen that the fluid pressure is so much higher than, for example, the Co ² pressure, and in this case, the desired carbonation of preferably tap water in which the fluid pressure within the housing of the pressure control valve does not produce the existing and instantaneous fluid pressure during the tapping and forced carbonation via the in-line carbonator (5) further to the gas flow and the required differential pressure of gas to the liquid. This means: if the liquid pressure increases, so does the gas pressure, the liquid pressure drops, so does the gas pressure and thus can be further carbonized even with strong or short-term pressure fluctuations and thus easily tapped on preferred tap (l). (Figurative not shown)

Also, you can use the Stillwasserkreislauf (9) (10) to keep the Accompanying cooling up to the taps (1) upright. (Not pictured)

Or with the pump (15) to feed an additional still water circuit (9) (10) which can be used as accompanying cooling up to at least one tapping point (1). This has the advantage that the standing liquids do not heat up. This is especially necessary for beverage supplements, which are mainly used in post-mix drinks.
