A kind of reclaim the method for aromatic substance in steam in tea brewing
Technical field
The present invention relates to a kind of reclaim the method for aromatic substance in steam in tea brewing, belong to Folium Camelliae sinensis and make tea technical field.
Background technology
One cup of good tea bubbled out, except having the soup color bubbled out specific to limpid bright millet paste and this tea, also should have graceful lasting fragrance and the sweet refreshing flavour of fresh alcohol.The people often having tea when sampling tea all can Wen Qixiang, see its color, its taste of product, the fragrance of tea sucked when sampling tea the most just can ooze into heart spleen, and refreshment, to the enjoyment of a kind of U.S. of people.Therefore, the fragrance of tea is always that people evaluate tea quality and the leading indicator of technological level of making tea.
On the one hand, the fragrance of tea and local tea variety, the manufacture method of Folium Camelliae sinensis is relevant, and the different teas fragrance that such as green tea, black tea, oolong tea bubble out is not quite similar;On the other hand, the fragrance of tea also has the biggest relation with brewing technique.Brew in technique in traditional craft, tea fragrance grasp the full experience by tea ceremony teacher and skill, liquidate soaked temperature, the control that brews the water yield and brewing time of tea ceremony teacher all can produce impact to the fragrance of tea.
Use tea demand owing to traditional manual tea-making technique can not meet a large amount of of service reception industry, (as catering industry with tea demand, convention use tea demand etc.), occur in that various making tea machine in recent years.Emerging of making tea machine, improve service reception industry supplies tea efficiency, preferably solve a large amount of of service reception industry and use tea demand, but in order to make for tea quality basically identical (i.e. supplying what is called " Standard China Green Tea "), generally employing standard is made tea technique, tea after once making tea would have to abandon, and causes the waste of Folium Camelliae sinensis, adds cost;In order to overcome this shortcoming, the Intelligent full-automatic tea making machine occurred recently begins with two bubbles or three bubble techniques, extends the tea-making time of Liang Pao and three bubble respectively.Although it can make the confession tea qualities such as millet paste that Tou Pao, two bubbles or three bubbles go out, soup color specific to this tea and flavour basically identical, but the fragrance of tea is constantly distributing, the fragrance the most backward given out in tea is the fewest, want to make for tea quality basically identical (i.e. supplying what is called " Standard China Green Tea "), make that the fragrance of the tea that Tou Pao, two bubbles or three bubbles go out is basically identical becomes a great problem.
Its reason is, existing making tea machine, during brewing tea, brews outside the steam of generation needs by pipeline discharge machine, the aromatic substance during water vapour has also taken away a part of tea simultaneously, decrease the aromatic substance quality entering storage mug accordingly, so that the tea of tea is fragrant thin out.
Summary of the invention
It is an object of the invention to, in order to solve existing making tea machine during tea-making aromatic substance can the problem of row outside steam, disclose and a kind of reclaim the method for aromatic substance in steam in tea brewing.
The technical scheme present invention utilizes the set point of the aromatic substance in tea steam the feature of 60 DEG C-80 DEG C, when Folium Camelliae sinensis brews in brewing cylinder, can produce the substantial amounts of tea steam rich in tea aromatic substance;The present invention, by the tea steam suction condenser containing tea aromatic substance, makes the cooling liquefaction of tea aromatic substance;Preserve not re-evaporation together with being mixed with tea by the tea storage cylinder of the tea aromatic substance liquefied introducing temperature slightly below 60 DEG C again, thus the recovery completing aromatic substance in steam in tea brewing preserves process.When tea is released from storage cylinder, the tea of releasing is again heated to 80 DEG C by the electric heater in tea tap, tea aromatic substance in tea will be released together in company with the tea of heating, the most no matter when releasing tea from tea storage cylinder, people can smell the fragrance given out in tea.
The present invention is on the basis of existing making tea machine, increase a condenser structure and a tea tap with temp. controlling electric heater, pipeline above tea water pouring cylinder of the steam that produces after tea-making is entered the condensing tube of condenser by condenser structure, it is passed through cold water or cold air in the periphery of condenser tube, the tea steam in condensing tube is made to be condensed into rapidly water, these condensed waters carrying tea aromatic substance enter tea storage cylinder from another pipeline, tea aromatic substance is recovered to temperature in tea storage cylinder and is less than the tea of tea aromatic substance set point, owing in storage cylinder, tea temperature is less than tea aromatic substance set point, tea aromatic substance no longer volatilizees in storage mug, but be mixed in tea, play the effect of " Chu Xiang is in tea ";And can make the tea of releasing exceedes the boiling point of tea aromatic substance with the tea tap of temp. controlling electric heater, make the tea aromatic substance contained in the tea of releasing again evaporate the fragrance becoming tea.
Condensation can take cooling piece to condense, it is possible to takes cold water to condense.Take cooling piece condensation to be attached on condensing tube by cooling piece, and increase air-cooled convection current, made by cooling piece the temperature of condensing tube reduce, it is achieved the condensation of tea steam in condensing tube;Taking cold water condensation is to add low-temperature cold water, by the heat exchange between low-temperature cold water and condensing tube, it is achieved the condensation of tea steam in condensing tube at condensing tube peripheral space.Two kinds of condensing mode principles are the same, but the former condensation vessel volume is little, and the latter's volume is relatively big, can be respectively suitable for the making tea machine of different model specification.Should ensure that with the tea tap of temp. controlling electric heater and the tea of temperature slightly below 60 DEG C can be heated rapidly to more than 80 DEG C when tea is discharged from tap, make the tea aromatic substance in the hot tea water of discharge progressively flash to the fragrance of tea.
The invention has the beneficial effects as follows, the present invention uses the steam of condenser condensation tea-making water generation at making tea machine, and the condensing hot air furnace being carried tea aromatic substance enters in tea, preserves in the tea storage cylinder of slightly below 60 DEG C;Make tea temperature exceed the boiling point of tea aromatic substance further through the tea tap with temp. controlling electric heater when releasing tea every time, the tea aromatic substance contained in the tea of releasing is made to evaporate the fragrance becoming tea in teacup successively, substantially increase the tea smell brewing tea, to savoring drink, person brings fine enjoyment, and make the tea fragrance level in the tea that different periods releases basically identical, make the fragrance also standardization of tea.The present invention brews mode ratio with existing, considerably reduces the loss of tea aromatic substance during making tea, and uses full-automatic tea the technology tea bubbled out and the tea manually making tea out fragrant at tea and reaches unanimity further in mouthfeel.
The present invention is applicable to making tea machine.
