Definitions
- the present invention concerns a draught beverage dispensing font.
- the present invention also concerns a method for manufacturing such a font.
- Draught beverage dispensing fonts are well-known in the art, and they are in particular used to dispense alcoholic beverages, like for example beer.
- cooled fonts are known, in which either condensate or frost is produced on the outer surface of the font casing, as a visual indication of the cool temperature of the beverage being dispensed.
- condensate or frost is produced on the outer surface of the font casing, as a visual indication of the cool temperature of the beverage being dispensed.
- the casing of such cooled fonts is expressly designed to produce either condensate or frost on the outer surface thereof.
- the casing's walls themselves are cooled by a piping which is integrally formed inside such walls, said piping defining an evaporator unit of a cooling apparatus which carries out a closed refrigeration cycle.
- a draught beverage dispensing font manufactured according to the aforementioned prior art has some drawbacks, the main one of which is linked to the fact that, when it is desired to convert an existing non-cooled font to a cooled font, it is necessary to substitute at least all the existing casing with the aforementioned cooled-type casing.
- the technical problem at the basis of the present invention is to provide a draught beverage dispensing font that allows a cheap conversion of existing non-cooled font, so as to overcome the drawbacks aforementioned with reference to the prior art, in a simple and effective manner.
- the present invention in a first aspect thereof, concerns a draught beverage dispensing font, comprising a font casing, and cooling means associated with said casing, said cooling means being suitable for producing either condensate or frost on at least one outer surface of said casing, characterised in that said cooling means are structurally distinct from said casing and they are arranged in heat exchange relationship with at least one surface of said casing.
- the aforementioned font can be advantageously fitted to the design of an existing non-cooled font, so that existing non-cooled fonts can be converted to cooled types without the need for a new font design.
- the cooling means of the font of the present invention can be retro-fitted into fonts that have not been initially designed with this feature of condensate or frost in mind.
- control over the temperature of the font surface is simple and automatic, guaranteeing the desired either condensation or frosting, independent of surrounding environmental conditions.
- the font of the present invention allows for the transfer of the cooling means from one font to another - with minor adjustments - should the favoured design of font change over time.
- the aforementioned cooling means are arranged inside said casing and in heat exchange relationship with at least one inner surface of said casing.
- the aforementioned cooling means define an evaporator unit of a cooling apparatus adapted to carry out a closed refrigeration cycle.
- Such an evaporator unit is advantageously easy to be controlled, intervening on the known parameters of the closed refrigeration cycle, so as to produce the desired condensate or frost on the outer surface of said casing.
- the aforementioned cooling means comprise at least one pipe which is at least partially coil-shaped.
- coil-shaped pipe it is meant a pipe whose longitudinal axis substantially has the shape of a coil or of a zigzag line.
- the coil-shaped pipe has the advantage of increasing the heat exchange surfaces.
- the font of the present invention when the cooling means are arranged inside said casing, further comprises at least one draught beverage line arranged inside said casing, and the aforementioned pipe is at least partially wound around said at least one draught beverage line.
- insulating means are interposed between said at least one draught beverage line and said pipe.
- the font casing of the present invention is preferably heat conductive, and more preferably is made from a cast metal.
- the present invention concerns a method for manufacturing a cooled draught beverage dispensing font comprising a font casing, the method comprising the steps of:
- the cooled font - manufactured by the aforementioned method - separately or in combination has all of the structural and functional characteristics discussed above with reference to the aforementioned font of the present invention and therefore it has all of the aforementioned advantages.
- the aforementioned arranging step of the method of the present invention is preferably performed arranging said cooling means inside said casing and in heat exchange relationship with at least one inner surface of said casing.
- the aforementioned method further comprises the step of providing a cooling apparatus adapted to carry out a closed refrigeration cycle, wherein said cooling means define an evaporator unit of said cooling apparatus.
- the aforementioned arranging step of the method of the present invention is also performed at least partially shaping like a coil at least one pipe comprised in said cooling means.
- the aforementioned arranging step of the method of the present invention is preferably performed at least partially winding said at least one pipe around at least one draught beverage line arranged inside said casing.
- the method of the present invention further comprises the step of interposing insulating means between said at least one draught beverage line and said at least one pipe.
- a draught beverage dispensing font in accordance with the present invention is shown. Such a font is globally indicated with 10 and it is preferably made from cast metal.
- the font 10 comprises a font casing 12 and cooling means 14 associated with the casing 12, such cooling means 14 being suitable for producing either condensate or frost on a outer surface 16 of the casing 12.
- the font 10 comprises one or more draught beverage line 18 arranged inside the casing 12, which ends with one or more draught beverage distributor 20 (four distributor 20 are shown in figure 3 ).
- the beverage lines are connected to a beverage tank.
- the cooling means 14 are structurally distinct from the casing 12 and they are arranged in heat exchange relationship with a surface of the casing 12.
- the cooling means 14 are in relationship with a inner surface 22 of the casing 12.
- the casing 12 shown in figure 3 is formed by a front shell 12a and a rear shell 12b.
- the cooling means 14 define an evaporator unit 24 of a cooling apparatus 26 adapted to carry out a closed refrigeration cycle.
- the cooling apparatus 26 comprises the evaporator unit 24 and a condensing unit 28 connected together through refrigerant fluid tubes 30 so as to define a gas-tight, closed refrigeration cycle.
- the refrigerant fluid tubes 30 are flexible narrow gauge tubes, i.e. capillary gauges.
- the expansion step of the closed refrigeration cycle is carried out in the capillary gauges (in other words, the closed refrigeration cycle is of the so-called "direct expansion" type).
- the evaporator unit 24 is preferably of the coil type (or of the plate type), and it comprises a matrix designed to suit the particular shape of the available inner volume of the font 10.
- the pipe 24a of such a coil is wound around the draught beverage line 18, so as to realize a bespoke evaporator.
- Insulating means 25 are interposed between the draught beverage line 18 and the aforementioned pipe 24a of the coil.
- the insulating means 25 are part of the aforementioned matrix.
- the condensing unit 28 preferably of the vapour compression refrigeration type, comprises an hermetic compressor, a forced air condenser coil (with possible electric fan), a heat exchanger/receiver cylinder and associated connecting tubing and electrical controls.
- two pressure switches are mounted in the suction line of the compressor.
- One is set at a safety pressure, to protect the compressor, and equivalent to an evaporating temperature of -20°C, which is sufficient to freeze the outer surface 16 of the font 10.
- the other switch is set at a pressure equivalent to an evaporating temperature of -5°C, which is sufficient to create condensation on the outer surface 16 of the font 10 under all practical ambient conditions.
- a selector switch in the electrical control circuit allows one or other of these switches to control the operation of the compressor, offering a choice between the frozen effect and the condensing effect.
- Air cooled condensing unit 28 ejects heat energy to atmosphere and the refrigerant fluid carries heat energy away from font 10, so that moisture condenses out of air onto the cold outer surface 16 of the font 10.
- the temperature of the outer surface 16 In order for the font 10 to "sweat", the temperature of the outer surface 16 must be below the dew point of the surrounding air.
- the outer surface 16 of the font 10 needs to be cooled to the dew point of air at 18°C and 30% RH (Relative Humidity). This means that the outer surface 16 of the font 10 needs to be kept at just above 0°C.
- FIG. 5 shows the operating principles of the cooling apparatus 26.
- the pressure in the evaporator unit 24 is controlled by the compressor.
- the evaporating temperature (or boiling point) is controlled by the pressure, according to the known "Charles Law".
- the cooling apparatus 26 In order to maintain the outer surface 16 of the font 10 at 0°C the cooling apparatus 26 needs to maintain an evaporating temperature of around -7°C. For instance, with the refrigerant fluid R134a, this corresponds to a pressure of 18 psig (about 1.24041 bar).
- FIG. 6 shows the operation in condensing mode of the cooling apparatus 26.
- the pressure in the evaporator unit 24 is controlled by the pressure switch 32.
- the compressor will continue to draw vapour from the evaporator unit 24 until a pressure of around 5 psig (about 0.34456 bar) is reached. For instance, with the fluid refrigerant R134a, this corresponds to a temperature of -18°C.
- Figure 7 shows the operation in frosting mode of the cooling apparatus 26.
- the pressure in the evaporator unit 24 is controlled by the compressor.
- the pressure switch 32 is over-ridden.
- a rocker switch can be provided, which is set to a "frosting" position.
- the power to the apparatus 26 is turned on at the mains outlet.
- the apparatus 26 is allowed to run for approximately 15 minutes in this condition. If the desired effect is frosting, the apparatus 26 has to continue to run.
- the pressure switch 32 is now over-ridden and the outer surface 16 of the font 10 will start to frost.
- the rocker switch After the initial 15 minute period, if condensation is required on the outer surface 16 of the font 10, the rocker switch has to be switched to a "condense" position. This brings the pressure switch 32 into circuit and the apparatus will maintain the font temperature at just above freezing.
- the condensation will start to form on the font in 10-15 minutes, whereas the frost will start in 20-30 minutes.
- the apparatus 26 uses a very small quantity of fluid refrigerant, preferably R134a, which has a zero ODP (Ozone Depletion Potential).
- the present invention also concerns a method for manufacturing a cooled draught beverage dispensing font, comprising the steps of providing cooling means structurally distinct from the font casing, and arranging the cooling means in heat exchange relationship with a surface of the casing, so as to produce either condensate or frost on the outer surface of the casing.
