Description
Technical field
The present invention relates to coffee pot field, especially a kind of portable pressure-controlled segmentation is drawn water concentrated coffee pot and its user
Method.
Background technology
Concentrated coffee（ Espresso）It is that business makes most of now mill fancy coffees（Such as latte, mocha, caramel）'s
Basis.According to《 Espresso Coffee The Chemistry of Quality》It is dense to make a standard for the definition of one book
Contracting coffee has to comply with following condition：The temperature of water：Target temperature is 90 ± 5 DEG C, if water temperature is too low, can cause to extract
Deficiency, the substance inside coffee are unable to fully discharge, can only so cook one glass of flavor deficiency, taste meta-acid Espresso；
Once water temperature is too high, excessive extraction can then make coffee generate bitter taste and astringent taste.
The pressure of water：Target hydraulic pressure is 9 ± 2 bar（About 1MPa）, general brewed in hot water method can only extract in coffee
The water-soluble substance in portion, and Espresso can extract the non-substance for being dissolved in water further by high pressure.These hydraulic pressure will make coffee
Lipid inside coffee（ Lipophilic Substances）Emulsification completely, dissolves in water, this is " alcohol taste "（ body）It is main
Source.
Emulsification can make the mouthfeel of Espresso more sticky, and people is allowed to drink the sense of " such as velvet-like gently sliding fine and soft "
Feel；And it is sticky can form lower surface tension, can more invade taste bud, make it is aromatic reverberate within oral cavity, do not dissipate for a long time.
Extraction time：The length of filtration time can influence the number of water yield, and Espresso extracts coffee with high-pressure water heating
Flavor, task can be completed within about 25 seconds（After this period, the liquid flowed out does not have taste, only can be dilute
Release Espresso）.
Currently, the coffee shop of commercial operation or other business Fresh Ground Coffee providers, in order to make a concentrated coffee
The commercial espresso machine of relatively large-scale must be used, weight and size all cannot achieve mobile operation, and it is expensive
Price also allow numerous small-scale coffee operators to bring larger cost pressure.
And be in under scene, existing commercialization espresso machine is since occupied space volume is big, price is high, operation difficulty
Greatly, it is also difficult to the selection for becoming family consumer, the espresso machine or other coffees of the selection domestic type that can only have to take the second best
Pot, but housed device most of on the market can not make the product for reaching standard concentrated coffee requirement at present.
Invention content
The technical problem to be solved by the present invention is to：It is above-mentioned in order to solve the problems, such as, it provides a kind of portable voltage-controlled
Formula is segmented the concentrated coffee pot that draws water, and high pressure is supported simultaneously to provide pressure adjusting function, segmentation pumping function, to reach concentrated coffee extraction
Target hydraulic pressure, water temperature, extraction time requirement and the flavor individual requirement taken.
The technical solution adopted by the present invention to solve the technical problems is：A kind of portable pressure-controlled segmentation is drawn water concentrated coffee
Pot, including kettle body and siphon pipe are provided with coffee powder tank in the kettle body；Further include voltage operated device, voltage operated device is set to rainbow
In suction pipe, for adjusting concentrated coffee target extraction hydraulic pressure and water temperature.
Preferably, the voltage operated device includes piston and is set to the opening of piston base, kettle body inner air pressure
When reaching preset pressure, jacks up piston and draw water to extract the ground coffee in coffee powder tank.

The unilateral buckle closed.
Preferably, the upper opening week edge of the kettle body is provided with and renovates corresponding sealing ring with buckle-type；It is described close
The side edge of seal, which is provided with, pulls tail.
Preferably, the upper opening of the kettle body be provided with installation sealing ring annular groove, annular groove side be provided with
Pull the corresponding notch of tail；It is additionally provided with safety relief valve in the middle part of the kettle body.
Preferably, the bottom of the coffee powder tank is provided with down tube of drawing water.
Preferably, being additionally provided at least one buffering strainer in the siphon pipe.
Preferably, the voltage-controlled knob outer is provided with scale.
The present invention also provides a kind of portable pressure-controlled application methods for being segmented the concentrated coffee pot that draws water, including following step
Suddenly, 1）The quantitative pure water of injection in kettle body, makes liquid level higher than lower bottom of the tube of drawing water, is less than safety relief valve；
2）Ground coffee is positioned in coffee powder tank；
3）It closes buckle-type to renovate and fasten with buckle, kettle body, down tube of drawing water, coffee powder tank, siphon pipe communicate, by voltage-controlled mould
Block obstructs to form confined space；
4）Voltage operated device is rotated, target extracting pressure is set；
5）Kettle body bottom is heated using open fire heat source or electric heat source, until water heating is stepped up pressure inside confined space
Power；When internal pressure is more than 1bar (0.1Mpa), start compressed air volume inside confined space；
6）Before internal pressure is more than 1bar, is less than default extracting pressure, lower pot extracts quantitative hot water pre-soaking ground coffee；
7）It is more than default extracting pressure moment in internal pressure, inside will be by siphon pipe quick pressure releasing, and kettle body hot water is with certain
Hydraulic pressure it is quick（The standard extraction time）Across ground coffee, voltage-controlled module, buffering strainer, target cup is finally entered with normal flow
Tool.
8）Buckle is opened, tail is pullled and carries out internal and external pressure balance with fast quick-detach kettle body, take out coffee powder tank, clearly
Ground coffee is replaced after clear, carries out step 1）- 7）Make lower a cup of Java.
The beneficial effects of the invention are as follows：A kind of portable pressure-controlled segmentation is drawn water concentrated coffee pot and its application method, is had
Following advantages：1, equipment volume is smaller is convenient for carrying, supports to use under non-transformer environment, provides wider coffee and drinks field
