Definitions

  • the present invention relates to an improved method and machine for optimizing the quality of extracted coffee drink.
  • the invention relates to an improved method and coffee machine, wherein the flow characteristics of the extracted coffee drink into the receptacle is monitored and if found to be deviating from reference value, the brewing temperature and time are corrected to improve the flavours extracted from the ground coffee powder.
  • espresso coffee and espresso based milk drinks are gaining in popularity in many parts of the world.
  • Coffee coffee is normally made from approximately 5-9 grams of ground coffee for a single serving, and when prepared well, it has excellent flavours. It has a small serving size of approximately 15-40 ml, a thick consistency as compared to other brewing methods, a higher concentration of dissolved solids and thick foam commonly known in the trade as "Crema'.
  • Coffee coffee brewing process either on their own or by influencing the other parameters or both, e.g. type of coffee or coffee mixture, roast level and roast profile, moisture content, ambient humidity, time after roasting and grinding etc.
  • the brewing parameters In order to produce a high quality espresso drink with an optimum percentage of dissolved solids, the brewing parameters have to be carefully adjusted to optimize some or all the above mentioned factors, which may normally affect the brewing process.
  • the first condition is associated with a weak brew, underdeveloped flavours and high sourness, which are caused by a low extraction pressure and/or low temperature, and
  • the second condition is associated with a very strong brew and highly unpleasant bitterness, which are caused by a high extraction pressure and/or high temperature.
  • the brewing pressure of more than 9 bar is developed by the action of the pump acting on the dose of ground coffee powder placed on a filter member.
  • the function of this filter member is to allow the extracted beverage to flow through, but to disallow the ground coffee powder to pass to the beverage receptacle, e.g. a coffee cup.
  • the pressure is normally adjusted by regulating:
  • Patent document DE 10 2009 049229 Al (WMF, Casado Gomez Sebastian+) describes a coffee machine, which calculates the grind particle size of the ground coffee coming out of the grinder by checking the volume and mass of the ground coffee and which corrects the brewing pressure for the subsequent brewing cycle by changing the grind particle size by adjusting the mean distance between the two grinding discs in the coffee grinder.
  • Patent document WO 2009/0101909 discloses a method for controlling a coffee machine grinder by measuring the percolation time, percolation rate and percolation pressure and by changing the grind particle size by adjusting the mean distance between the two grinding discs in the coffee grinder. Both the above patent documents have the following limitations:
  • Patent document EP 2314182 Al (Gruppo Cimbali, Coccia Andrea) describes a system for controlling the brewing/dispensing pressure by varying the pump output flow rate.
  • Patent document WO2011/055189A (La Marzocco Sri., Bianchi Roberto; Ellul-Blake Jacob) describes an improved method for preparing espresso coffee by manually adjusting or manually setting the automatic control of the brewing water pressure developed by the pump to suit different types of coffee.
  • adjusting the pressure developed by the pump also has limitations, because if the dose of coffee is not offering enough resistance to the flow of water and the water is flowing too fast through the dose of coffee, then reducing the pressure/rate of flow will, to an extent, help in extracting an increased percentage of flavours from the ground coffee powder but at the same time, the reduced pressure will not be adequate enough to extract the flavours from the ground coffee powder properly, resulting in a coffee beverage that is still too thin, sour and with underdeveloped flavours.
  • espresso coffee is to be extracted within an optimum temperature range around 90 degrees.
  • the temperature is controlled by suitable temperature sensing devices, which are commonly known in the art.
  • Patent document EP2050372Al (Gruppo Cimbali, Coccoa Andrea) describes a system, in which the optimum temperature is maintained constant throughout the brewing process by means of a controlled mixing of cold water into the hot water line disposed downstream of the heat exchanger.
  • Optimum extraction time can range from 20-30 sees for a 15-40 ml of beverage extracted from a dose of approximately 5-9 grams of ground coffee powder, depending on coffee, roast, grind, moisture etc... and such other factors, already listed above.
  • the extraction time is normally controlled manually by a visual inspection of the extracted beverage, or is a "fixed" time value - programmed into the machine control system.
  • an experienced espresso machine user/operator routinely/intuitively monitors the flow characteristics visually on a manually operated espresso machine in order to determine, whether the extracted beverage is of high/desired quality or not.
  • Some prior art machines also monitor the flow volume by means of a flow sensing device, which measures the volume of water pumped into the heating device. In such monitoring process, it is assumed that the volume delivered to the beverage receptacle is equal to the volume delivered to the heating device. However, this assumption does not always hold good, because some of the water delivered to the heating device ends up as residue or is captured by absorption or other losses taking place in the brewing device and other parts of the hydraulic circuit of the machine.
