By sucking in the concentrate and through it achieved mixing of the two flow media is obtained at the output of the device a concentrate-water mixture.
  • the mixing ratios are usually over different in conventional mixing devices Cross-sectional areas of the channels set, d. H. the mixer must be for the provision of a different mixing ratio are exchanged. This is very consuming, as there are high demands on hygiene for the dispensing of drinks become.
  • the concentrates may have a different viscosity or viscosity, in particular also influenced by the different ambient temperature, so that at different Conditions different mixing ratios are obtained.
  • the known mixing devices there is no way to simple and inexpensive Regulation of the mixing ratio.
  • the invention is therefore based on the object, a device of the aforementioned Kind of improving, such that the mixing ratio between two flow media, especially between water and a beverage concentrate, set in a simple manner irrespective of the concentrate composition, i. H. With few or many solids fractions, with high or low viscosity and the like. Possible should be. Furthermore, the mixing device should be streamlined and cost-effective be produced and ensure a safe function even in intermittent operation.
  • At least one bypass channel to the first passage and means for adjusting the flow rate the first and / or the second fluid are provided. That way regardless of the viscosity or of the problem that fruit pieces in the concentrate contained in a simple manner, any mixing ratio for the two Adjust fluids.
  • the second passageway formed in the first passageway opens have a relatively large cross section, so that the solids content the beverage concentrate can flow through the cross section unhindered, since the Mixing ratio depends only limited on the cross section of the second passageway.
  • the mixing device does not have be replaced, so that when changing the mixing ratio and no hygienic problems arise through the use of a new device. Should be the same Device another concentrate used, so can the device easy to clean due to their simple structure, which will be discussed later becomes.
  • the flow rate can be with the device either the flow rate of the first fluid and / or the adjust second fluid. Since with drink mixtures the first fluid usually consists of water is formed and the majority of the mixture consists of water, the mixing ratio can be vary in a very large area.
  • the flow rate is the first fluid via the bypass channel or the bypass channels adjustable so that one on an adjustment in the mouth region of the second passage in could dispense with the first passageway. The confluence could therefore be constructive be easily formed while the mixing ratio is practically indirect through the bypass channels is regulated.
  • the second passageway opens substantially vertically into the first passage, are in defined and calculable flow conditions are provided at the mouth region, which are similar to those in Venturi nozzles. Also in the second passageway is an adjustment provided, in particular, a fine adjustment of the addition of Concentrate allows, if concentrates with low or no solids content, such as As tea, lemon concentrate and the like., Are used.
  • the first passage channel an inlet region, a middle section and having an exit area, wherein the middle section a smaller passage area than the entrance area and the Has exit area.
  • the middle section is very much in relation to the inlet area and the outlet area short, for example, an extension of only 1.5 to 2 mm while the entrance area about 25 mm and the exit area about 40 can be up to 50 mm.
  • the second passage through which the beverage concentrate is supplied is, opens downstream of the small passage cross-section and substantially halfway into the first passageway.
  • the estuary is relatively close to the middle constricted portion of the first passageway, so that fruit juice concentrate through the accelerated water flow entrained, and therefore no supply of the concentrate under Pressure needs.
  • the one or more bypass channels run from the entrance area of the first passageway to the exit area and have a substantially constant cross-section. They extend parallel to the central portion of the first passageway, with their upstream end into the expansion chamber and with its downstream end at a distance from the mouth of the second Open passageways in the exit area of the first passageway.
  • the junction of each bypass channel is at an acute angle arranged to the axis of the first passageway and a taphole formed, which has a nozzle-like narrowing cross-section.
  • the confluence of the second passageway in the first passageway be educated.
  • metering devices For adjusting the flow rate of the fluid through the bypass channels or the second passage are metering devices provided, which can be inserted into the mouth openings are. These metering devices can advantageously be formed by pins be, which fitted with a seated at the mouth opening Tip are formed and adjustable in transverse bores by means of a fine thread are guided.
  • the mixing ratio can be adjusted arbitrarily in a simple manner. Even if the passage cross-section of the second passage channel substantially must be opened completely to allow passage of a larger one To allow quantity of fruit, is a dosage over the adjustable Bypass channels easily possible by the flow through the respective Bypass channel is precisely controlled.
  • the housing the mixing device preferably made of plastic and as one piece Injection molded body formed.
  • the housing may be a fastening device have and in the region of the free channel ends connecting piece for connection of connecting hoses, concentrate containers, liquid feeds and / or the like.
  • the connections can be known as quick-release connections be formed, which engage in corresponding grooves of the housing and their connection z. B. be sealed by an O-ring seal can.
  • closure devices in the hose connections are provided, which the inlet to the terminal end of the hose close before a corresponding flow connection to the inventive Device is made. Additional closure devices may be formed on the device inlet side itself to return flows from one channel to another channel.
  • the inventive device 1 for mixing at least two flow media has a housing 2, which in the illustrated embodiment is made as a one-piece injection molded plastic housing.
  • the housing has a first passage 3 with an inlet 4 and an outlet 5 and a second passage 6 with an inlet 7 and an outlet 8.
  • the passageway has the third an entrance area 9 with an enlarged cross-section, a middle section 10 with significantly reduced cross-section and an exit area 11th
  • the middle section 10 is relative to the inlet region 9 and the Exit region 11 is relatively short and ensures that the in Direction of arrow 13 pressurized water in the middle section 10 is significantly accelerated to from the outlet 8 of the second passageway 6 mitzui conference in the direction of arrow 12 supplied concentrate.
  • the outlet 8 creates a considerable turbulence and in consequence its a good mixing of water and concentrate.
