Description
Technical field
The present invention relates to the capsule that holds dried food substance (magazine, capsule) preparation supping.More particularly, the present invention relates to a kind of be used to prepare the foaming supping of the foam head (head offoam) with enhancing such as the method for hot drink, this supping mixes the soluble powder in the capsule of a kind of diluent and predetermined close mutually and obtains.The invention still further relates to the device that is applicable to this method.The invention still further relates to the capsule of the predetermined close that is applicable to this method.
Background technology
By the prepared effervescent beverage of dispensation machines, for example (Italian coffee with milk latte) becomes and more and more receives an acclaim for Italian type concentrated coffee (espresso), Kapp Cino Da Pistoia coffee (cappuecino), Sheng Sang.The method for preparing this product with the capsule of predetermined close also is known.That uses metering in advance is with wrapped a portion coffee and the analogue advantage with the practice of preparation coffee base beverage: help the preparation of beverage, guarantee that simultaneously the quality between every doses keeps constant with beverage concentration down at identical preparation condition (batching, temperature, pressure, time etc.).This method also provides bigger facility for the user.Capsule places a kind of leakproof shell of coffee-type machine of special use usually, and hot water passes this capsule under pressure.The downside of this capsule is owing to the increase of pressure is bored a hole to discharge this concentrate.To the use commercialization of the powder that cures and milled in capsule, to make high-quality coffee in cups.
EP 0512470B1 has illustrated a kind of method that extraction is positioned at the leak free material storage tube of a material storage tube (cartridge) holding element that is used for, and wherein the compound of water and air is injected into this material storage tube so that this extraction facial disfigurement under the pressure of 1 to 20 crust.The extraction face of this material storage tube abuts against on the embossed surface of this material storage tube holding element and deforms, this material storage tube holding element comprises relief element and recessed element, this extraction face is torn in the position of these relief element and/or these recessed elements when reaching rupture stress, so that after extraction coffee under the pressure of 1 to 20 crust, liquid can be removed subsequently.
This method proof is highly effective for coming extracting beverage liquid with a kind of material that extract, insoluble as the coffee that cures and milled.Because this product is soluble in material storage tube, this material layer keeps the internal drag of rising, and trends towards being increased to higher scope along with more water enters material storage tube pressure.High pressure, temperature and the combination of extraction time are very crucial for the compound from the meticulous fragrance of this layer of coffee extraction, can tear so that the liquid that is extracted flows in the cup up to this extraction face.
For soluble products, water is not to be used to extract solids and coffee aromatics, but is used to dissolve all solids.Dilution to solids mainly realizes by mixing fully in capsule up to diluting fully in time enough.And, should when introducing enough air, mix, so that form good foam or floating foam in flowing to cup the time.The foam of soluble powder produces very complicated, and may depend on that solution passes through the physical condition that this capsule flows out.These physical conditions comprise the level of shear that produced and the release of pressure by opening.In addition to selecting the increase and the drop away time of pressure, so that in solution, obtain to mix fully and introduce enough air.Problem is that when liquid began to enter capsule, powder begins dissolving and solution trends towards discharging.Because the solid contents in the capsule descends, and is descended pro rata by the resistance that powder produced in the capsule.As a result, solution trends towards discharging from capsule too quickly under low excessively pressure, and does not mix fully.Because undercompounding may form caking in the solution of being sent, the air deficiency amount of being introduced, thereby the foam volume that is produced is seldom.
The US3292527 of Stase relates to a kind of equipment and material storage tube that is suitable for sending continuously different drinks or beverage, and drink or beverage are contacted with the primary element of this equipment.This material storage tube can comprise meticulous soluble powder, and has the bottom of perforation, and its generation can hinder the pressure drop of liquid by this hole outflow.Even this perforation be provided with itself when this perforation is very little, can not produce enough shearings yet and can not keep enough pressure in inside, so as can to produce stirred rightly foam or the foaming beverage.
The EP0468080 of Fond relates to also that a kind of extraction is used to cure and the method for the material storage tube of the coffee of milling, and wherein this material storage tube has the bottom of a perforation so that send the liquid that this extracts along a very big surface.This method is used to (coffee) that cures and milled, but is not suitable for for example instant coffee powders of soluble powder, and its reason is identical with US3292527.
The WO 01/58786 of Halliday relates to a kind of material storage tube of machine preparation " Italian type concentrated coffee " type effervescent beverage that is used under low pressure operating, it is characterized in that, this material storage tube is combined in the flow of beverage path, the outlet before or the exit, be used to produce the device of beverage jet, at least one is used for the import of air, and the device that the pressure of beverage jet is reduced, thus in use, become many little foamings from the air of air intlet and be combined in the beverage.Because the low pressure in the material storage tube is so air must be added into by the air intake of special use.This material storage tube relates to many parts particularly, and is therefore very hard to tackle, complicated, and the productive costs costliness.
Need a kind of system that produces supping such as coffee base product, this product has the good bubbling character that obtains from the capsule-type system, this system adopts better simply and material storage tube cheaply, and this material storage tube can make soluble food dissolve fully basically and produce a large amount of foams.
