Definitions

• the invention relates to a method for applying decorative representations on a multilayered surface of coffee, in particular on a crema, as well as a device for carrying out the method.
• Coffee is today served in the coffee cup predominantly with a light topcoat on the surface.
• This cover layer is created automatically in espresso machines and is called a crema.
• a crema-like topcoat can also be made by a small amount of milk froth.
• additional structural measures are provided to form a surface in the manner of a crema.
• the surface of coffee is decorated with chocolate powder, by skilfully guiding a pot with frothed milk when pouring it onto the surface, or by a pointed stick with which ornaments can be drawn into the crema or the like.
• Such a complex device is described for example in JP 2015142699 A.
• different edible materials such as, for example, melted chocolate, whipped cream or a printing medium for an inkjet printer
• an air nozzle may be associated with the printhead with which an air jet is directed at the coffee surface.
• this jet of air has a very low pressure at the point of action and serves the purpose of smoothing out an uneven foam surface, as occurs, for example, in the case of milk foam, so that the print result produced by the subsequently guided print head is improved.
• a strong focused air jet which leads to turbulence in the multilayer surface would be a hindrance here, since this destroys the printing surface.
• the invention now aims to provide a method for applying decorative representations on a multi-layered surface of coffee in the coffee cup, which leads easily with little effort, without further ingredients and permanently to the goal.
• the air jet has a low intensity, but sufficient to penetrate the crema or the like. And purposefully mix with the air or the black coffee below localized.
• the air jet pushes the crema locally to one side, on the other hand it whips the crema together with black coffee, limited to the smallest space, so that the crema discolors there. If the air jet is guided, lines of distinguishably different color arise on the light crema or the top layer. The effect lasts for a long time.
• the lines that represent a flower or a monogram, for a long time remain sharp without dwindling. For example, an ornament or monogram is still visible after about 15 minutes.
• the adjustment of the pressure of the air jet can be selected according to the respective surface by the expert. When setting the pressure, it is very easy to see from which pressure the turbulences occur, since here the visible dots or lines of different coloration appear on the multilayer surface. If the pressure is increased beyond that, then the width of the resulting line can be adjusted.
• the invention also relates to a device for carrying out the method.
• a device for carrying out the method This is characterized in that in a housing of an elongated hand-guided pin, a compressed air source and a switching element, in particular a metering valve for the air jet, and a pin projecting, preferably longitudinally displaceable air guide tube are provided.
• the pen contains all the components to create a focused jet of air.
• the pen is self-sufficient and can be easily carried.
• the switching element allows the sensitive switching on and off as well as dosing of the intensity of the air jet during drawing and writing.
• the switching element is in a particular embodiment as a metering valve next to the tip of the character on the jacket of the housing and is operated with the index finger.
• the intensity control of the air jet is possible in this way by changing the pressure of the index finger on a spring-loaded pusher of the switching element.
• a pump with an attached compressed air vessel - with check valve at the entrance and metering valve at the output - Similar to a mechanical pencil, a pusher protruding at the upper end is repeatedly pressed against spring force. The air compressed in a cylinder thereby enters the compressed air vessel, with a check valve allowing pressure to build up. Via a metering valve, the air jet is switched on and regulated at the tip of the air guide tube.
• a compressed air filled replaceable capsule in the pen as a compressed air source.
• a membrane of the capsule is broken and now can be switched on with a pressure reduction and the metering valve, the air jet and its intensity can be controlled as needed.
• a particularly expedient embodiment of the invention is characterized in that a fan driven by an electric motor is provided as the compressed air source and an electrical switch, possibly with voltage regulation, is provided in the housing as a switching element.
• the components are so compact that they can easily fit in the pin housing of about 12 to 15mm in diameter and a length of 80 to 100mm.
• the speed of the fan controls the intensity of the air jet.
• Such a pin according to the invention can be mounted in a holder on any espresso machine and is thus available immediately in the production of the coffee.
• an ultrasonic sensor is arranged on the plotter, by means of which the distance of the pin to the multilayer surface can be measured, the values determined serving to set the optimum distance of the pin to the multilayer surface.
• the distance of the pin In order for the focused air jet to achieve an optimal result, it is also important to set the correct distance to the multilayer surface in addition to the guidance in the two horizontal spatial directions. Since the level in the vessel is not always constant, the distance of the pin must be realigned with each use. For this purpose, the distance can be determined by means of an ultrasonic sensor arranged on the plotter, after which the pin is correspondingly adjusted in height to achieve an optimum result.
• FIG. 1 shows a somewhat enlarged longitudinal section of a pin with a pump
• 2 a screw-on pin with replaceable capsule for compressed air
• 4 and 5 show a basic arrangement with plotter guidance of a pin according to FIG. 3.
• a pump 2 is housed in a tubular housing 1 of a pin, the piston 3 is actuated by means of a pusher 4.
• the pump is connected via a check valve 5 (ball valve) to a compressed air vessel 6.
• a metering valve 7 which can be more or less opened by means of a button 8 depending on the button pressure.
• To the metering valve 7 includes a telescoping air duct 9 here. This acts as a tip or writing tip as soon as a compressed air jet is released via the button 8.
• the tube tip is led just above the crema or the surface of the coffee and in this way decorative representations or lettering can be applied to this surface.
• Figures 4 and 5 relate to the use of a plotter 24 with a movable in the x-z plane arm 25, which carries a holder 26 for a pin - preferably the pin of Figure 3 -.
• the plotter 24 is controlled by a computer 27 in which various surface designs, monograms or the like are stored for retrieval. In this way, decorative elements on the surface 28, in particular on the crema of a coffee in a coffee cup 29, can be represented by the focused air jet.
