Definitions

  • the present invention refers to fast preparation of infusions or tisanes of vegetal matters in the form of leaves or flowers, in particular espresso tea, and more specifically a process and an apparatus for such a preparation.
  • the beverages usually obtained from infusion with hot water comprise coffee, tea, camomile and various other kinds usually called "tisanes”.
  • the starting vegetal matter consists of leaves (in particular leaflets, as in the case of tea) or by the flower, generally submitted to drying or roasting and is possibly submitted to grinding in a more or less coarse powder, even if the grinding is mainly adopted for making pre-manufactured doses in filter-paper bags (as, for example tea or camomile bags).
  • espresso tea will be made, without intending that in limiting sense, as it is to be meant as extended to any kind of the here above mentioned infusions and tisanes.
  • Tea is a beverage of very large consumption in the whole word and consists of an infusion in hot water of dried leaflets of a plant mainly farmed in the Far East. These leaflets are submitted to drying and roasting treatments changing according to the quality and in many cases, as already mentioned, ground in form of rather coarse powder.
  • the preparation of the infusion provides to boil water (for example in a boiler) to fill with hot water a vessel (teapot) usually containing the specified dose of tea leaves or powder in dried form.
  • a vessel usually containing the specified dose of tea leaves or powder in dried form.
  • the leaves are left in infusion for a time, which mainly is of a few minutes, after that the beverage is ready for the consumption.
  • the times required for this kind of preparation are in contrast with the very limited times of the usual hot beverage consumers prepared instantaneously, of which a typical example is espresso coffee (whose name comes just from the fact that the beverage is instantaneously prepared from a dose of ground coffee powder and can be immediately consumed).
  • a dose of espresso coffee with the presently used apparatus and processes is prepared in a few seconds, so that is compatible with the requirements of the consumer having at disposal a very short time for the consumption and is further compatible with consumption situations excluding the possibility of sitting down around a table and proceed to the above mentioned operations for preparing the infusion in the usual conditions.
  • the so prepared beverage does not have the desired organoleptic features, especially as regards the smell.
  • a more specific object of the present invention is to provide a process and an apparatus for preparing infusions and tisanes, particularly espresso tea.
  • Another object of the present invention is to provide an automatic apparatus for preparing infusions and tisanes, in terms of preparation procedures and times comparable with those for the preparation of espresso coffee.
  • the main object of the present invention is met by a procedure for preparing infusions and tisanes, of the kind in which hot water is got in touch with a dose of dried or roasted vegetal matter, in the form of leaflets, flowers or powder, characterized in that said dose is subjected to hot water at a temperature not higher to that of the water poured in the usual vessel for preparing the infusion or tisane, preferably at a temperature comprised between 75 and 98 °C, and a pressure comprised between 3 and 9 bars.
  • the apparatus for preparing espresso infusion or tisane is characterized by comprising a hot water supply, having controlled temperature, an infusion assembly comprising an infusing filter connected to said hot water supply and suited to distribute the hot water on the upper surface of a filter support expected to receive a dose of dried vegetal material, in form of leaflets, flowers or in powder having pre-set grain size, being said filter support provided with spout means for dispensing the beverage to a suitable vessel or cup, and means for supplying said hot water to said infusion assembly under a pre-set pressure.
  • said infusion assembly is mounted on a traditional machine at one or more infusion assemblies suited for preparing espresso coffee, apart the provision of means for controlling the temperature of the water supplied to the infusion assembly for preparing espresso infusion or tisane at a temperature lower than that suited for preparing espresso coffee.
  • a usual automatic machine of the kind comprising an infusion assembly, supplied by a dosing grinder for coffee, apart that the last article is omitted and instead is mounted a usual powder material supplier, such as that used in the traditional automatic machine for supplying the infusion assembly with a different coffee powder, as for example decaffeinated coffee.
  • a traditional automatic machine instead of the traditional dosing grinder is mounted a supply of dosed quantities of vegetal matter in the form of dried powder having suitable grain size.
  • a machine of the kind used for preparing espresso coffee from pre-pressed coffee powder bags unless instead of the above mentioned bags, are used bags, containing a powder of dried vegetal matter of the kind previously indicated, prepared through the same technique.
  • such a heat recover can be addressed to pre-heat the water assigned to produce steam, which is always provided in any apparatus for preparing hot beverages by infusion.
  • the beverage prepared with hot and pressurised water has specific organoleptic features which are different and are not comparable with those of then coffee prepared in traditional way (either moka or through percolator); on the contrary, in case of espresso tea according to the present invention the organoleptic features of tea infusion are those of the beverage prepared in traditional way and that is strongly surprising.
  • Figure 1 is a diagrammatic view of the components of an apparatus for preparing espresso infusions or tisanes according to the present invention and Figure 2 is a view of a variation in a component of the apparatus of Figure 1.
  • the apparatus depicted in Figure 1 comprises a water supply consisting of a tank 10.
  • a tank 10 instead of the tank 10 is possible a connection to the usual water main.
  • the water of the tank 10 is taken through a pipe 14 by means of a pump 12 and sent to a flow-meter 16, while the numeral 18 indicates a usual check valve.
  • the water From the flow-meter 16 the water enters the boiler 20 provided with a heating clad resistor 22. It is obvious that instead of the resistor 22 could be provided a usual gas heated boiler.
  • the boiler 20 is provided with a thermostat 24 for controlling the temperature of the water, which through the pipe 26, goes to an infusion assembly 28 under control of an electric valve 30. It is to notice that all the till now described components are of the kind traditionally used in the machines for preparing espresso coffee.
  • the infusion assembly is in turn provided with a filter or spout for distributing pressurised hot water on the whole surface of the dose 32 of tea powder or leaflets contained in the filter support 34.
  • the support 34 is provided with a dispensing spout 36 through which the espresso tea is downloaded in the cup 38.
  • the thermostat 24 will have to be set in such a way that the hot water leaves the boiler 20 at such a temperature to reach the infusion assembly at this temperature, so that it will come out from the boiler at such a temperature for compensating the possible heat losses undergone in the way from the boiler to the infusion assembly.
  • Figure 1 shows the case of a hand operated apparatus for what regards loading of the tea dose and unloading of spent tea grounds
  • Figure 2 shows the case of an automatic apparatus in which the infusion chamber 34, containing the dose of tea powder or leaflets, supplied, for example, by a drawer supplier, receives the hot pressurised water from the boiler and the pressurised infusion occurs by actuation of a piston 36, being the actuation of electromechanical, hydraulic or steam kind.

Abstract

L'invention concerne un procédé consistant à utiliser un ensemble d'infusion (28), de type adapté pour préparer les cafés expresso, dans lequel le support de filtre (34) est chargé au moyen d'une dose (32) à base de matières végétales sous la forme de folioles, de fleurs ou de poudre séchée ou torréfiée; puis à fournir à l'ensemble d'infusion (28) de l'eau chaude sous pression à une température correspondante à celle des préparations manuelles classiques d'infusions et de boissons. Ces infusions et/ou tisanes sont obtenues en un temps de préparation comparable à celui des cafés expresso. De préférence, le procédé décrit dans cette invention est mis en oeuvre pour produire un thé expresso.
