Description
Technical field
The utility model relates to coffee pot field, especially a kind of portable pressure-controlled segmentation is drawn water concentrated coffee pot.
Background technique
Concentrated coffee (Espresso) is business makes most of now mills fancy coffee (such as latte, mocha, caramel)
Basis.According to the definition of " Espresso Coffee The Chemistry of Quality " book, it is dense to make a standard
Contracting coffee have to comply with following condition: temperature: target temperature be 90 ± 5 DEG C, if water temperature is too low, will cause extraction not
Sufficient, the substance inside coffee is unable to fully discharge, and can only so cook the Espresso of one glass of flavor deficiency, taste meta-acid；One
Denier water temperature is too high, and excessive extraction can then make coffee generate bitter taste and astringent taste.
The pressure of water: target hydraulic pressure is 9 ± 2bar (about 1MPa), and general brewed in hot water method can only extract inside coffee
Water-soluble substance, and Espresso can extract the non-substance for being dissolved in water further by high pressure.These hydraulic pressure will make coffee
Internal lipid (Lipophilic Substances) emulsifies completely, dissolves in water, this is the main next of " alcohol taste " (body)
Source.
Meeting is emulsified so that the mouthfeel of Espresso is more sticky, people is allowed to drink the sense of " such as velvet-like gently slide fine and soft "
Feel；And it is sticky will 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 will affect the number of water yield, and Espresso extracts coffee with high-pressure water heating
Taste, can be completed within about 25 seconds task (be more than this period after, the liquid flowed out does not have taste, only can dilute
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 biggish 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 as the selection of family consumer, can only have to take the second best and select the espresso machine or other coffees of domestic type
Pot, but housed device most of on the market can not make the product for reaching standard concentrated coffee requirement at present.

Embodiment 3
The draw water application method of concentrated coffee pot of the portable pressure-controlled segmentation of the utility model includes the following steps, 1) kettle body
It is interior to inject quantitative pure water, so that liquid level is higher than lower bottom of the tube of drawing water, is lower than safety relief valve；
2) ground coffee is placed in coffee powder tank；
3) it closes buckle-type flip lid and is fastened with buckle, kettle body, down tube of drawing water, coffee powder tank, siphon pipe communicate, by pressing
Control module 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 inside confined space
Pressure；When internal pressure is greater than 1bar (0.1Mpa), start compressed air volume inside confined space；
6) before internal pressure is greater than 1bar, is less than default extracting pressure, lower pot extracts quantitative hot water pre-soaking ground coffee；
7) be greater than default extracting pressure moment in internal pressure, inside will by siphon pipe quick pressure releasing, kettle body hot water with
Certain hydraulic pressure quickly (standard extraction time) passes through ground coffee, voltage-controlled module, trimmer valve, finally enters target with normal flow
Cup.
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.
Wherein, if internal pressure is greater than the default extracting pressure of highest still without normal extraction, internal pressure will pass through
Safety relief valve releases stress, and needs quickly to stop heating at this time, after continue manual pressure release after the completion of safety relief valve releasing pressure automatically,
So checking that kettle body investigation is abnormal after pressure release.
The portable pressure-controlled segmentation of one kind described in the utility model is drawn water concentrated coffee pot, has the advantage that 1, equipment
Small volume is convenient for carrying, supports to use under non-transformer environment, provides wider coffee and drinks scene；
2, it supports high pressure and pressure adjusting function is provided, it is personalized with the hydraulic demand and the taste that reach concentrated coffee；
3, the control for realizing extraction water temperature is adjusted by pressure；
4, it realizes that the segmentation accurately controlled is drawn water, improves the raising of ground coffee extraction efficiency and product flavor quality；
5, buckle-type Quick Release kettle body Combination Design improves the working efficiency that coffee continuously makes；
6, can volume production and considerably reduce production with machine retail price needed for quality grade coffee.
Its voltage operated device can control the connection of siphon pipe 2 and outside or not be connected to, and then adjust concentrated coffee target extraction
Water intaking pressure and water temperature；Also, independent voltage-controlled mould group, it is detachable and interchangeable, can independent volume production and technology iteration upgrading；It dismantles independence
Coffee machine can still work normally after voltage-controlled mould group, can make the higher coffee of without grease, content of caffeine.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
