Description
Technical field
The present invention relates to a kind of method that utilization accumulation of energy coffee machine prepares espresso.
Background technology
The preparation of espresso (ESPRESSO) coffee, was usually required that with the high-temperature-hot-water of 90-95 degree, by 25-35 seconds
Time, with 9BAR or so pressure, by the ground coffee of appropriate grinding appropriateness, the active ingredient in ground coffee is extracted,
Form pyrosol.
It is visible at present dense for making Italian type because the preparation of espresso (ESPRESSO) coffee is higher to equipment requirement
The coffee machine of contracting (ESPRESSO) coffee substantially has following several：
Family expenses shake pump pressure type espresso machine：Using vibration pump simple in construction, normal-temperature water is pumped to electric hot plate and carries out hot friendship
Change, it is quick to produce HTHP hot water, by ground coffee, complete extraction.Advantage is cheap；Have the disadvantage：Pump pressure can not
The lasting requirement that stable 9BAR pressure is provided is met, makes coffee final product quality unstable.
Commercial sliding vane rotary pump heats homogeneous solution-type reactor coffee machine：Using flow and power very big sliding vane rotary pump normal pressure and temperature water, into advance plus
Warm a large amount of hot water are usually several liters or more than ten liters of high-temperature boiler, displace high-pressure water heating, by ground coffee, complete extraction.It is excellent
Putting is：Pressure, temperature stabilization, quickly can continuously make；Have the disadvantage：Expensive, energy consumption is larger, due to pump and water bath
The larger volume for also resulting in complete machine of the volume of stove is also very big.
Portable obstructed electric coffee machine：Gases at high pressure are stored by gas filling bottle or gas container in advance, pours into after hot water, uses high pressure
Gas impacts hot water, extracts coffee.Advantage is：Small volume, is convenient for carrying；Have the disadvantage：Air pressure is not enough or unstable, and part is more
For the plastic material of rapid wear, the consumptive material such as manpower inflation or extra gas cylinder is needed.
Traditional manual rod-pulling type coffee machine：First with the hot water in shorter but thicker piston suction boilers heated electrically, pass through larger manpower
Water is pressed directly or by compression brute spring secondhand kinetic energy, by taking general 58MM diameter pistons as an example, produced
9BAR pressure needs manpower to apply 238KG thrusts to piston by lever, completes extraction.Advantage：It is easy to use；Shortcoming：
Volume is larger, very arduously.
The present invention provides one kind by multiple pressurized hot water, accumulator is put aside after enough hot water and pressure potential, opens discharging valve
Door, makes spring promote piston press hot water bump ground coffee, the method for completing extraction process, and according to this method providing
The scheme of a variety of coffee Preparation equipments.
The method and equipment possess advantages below：The stable active force of spring release runs through whole pressure extraction process, pressure stability
Unanimously；Plurality of devices can be provided according to different schemes, can indoors or outdoor application；The preparation process of coffee is simple to operate,
The energy is saved, it is time saving and energy saving.
The content of the invention
The present invention provides a kind of method that utilization accumulation of energy coffee machine prepares espresso, and wherein accumulation of energy coffee machine is by rill calorimetric
Water pump, water suction check valve, hot water storgae, pressure water one-way valve, accumulator and brewing cavity composition, wherein accumulator include sealed cylinder block,

Coffee powder, injects hot water, hot water is pushed away between the piston and sealed cylinder block of accumulator several times by the small flow high pressure heat-exchanger pump
Piston moves up the spring of simultaneously compression accumulator, and spring is pressurized and deforms upon and put aside potential energy, and hot water, which is injected into, to be reached necessarily
After amount, the Draw off valve of accumulator sealed cylinder block bottom is opened, spring promotes coffee in piston press hot water bump brewing cavity
Powder, completes extraction process.
Piston is promoted to rise by the hot water for being pressed into sealed cylinder block, meeting compress energy storage spring, sends out energy-storaging spring when piston rises
Raw deformation storage potential energy, the compression stress of energy-storaging spring is to pass through Quantitative design according to the sectional area of piston, disclosure satisfy that every square
Centimetres more than 9 kilograms of compression stress.Water knockout drum is located at the entry position of brewing cavity, and hot water can be made to be changed into being uniformly distributed from water column
The network of rivers, hot water sufficiently uniformly contacts the ground coffee that is placed in advance in ground coffee bowl after water knockout drum, and ground coffee is equal in advance
Even grinding and deal is suitable, can produce suitable resistance, the size of wherein resistance is by people to the hot water pressurizeed by energy-storaging spring
To be realized by the granularity and grammes per square metre of experience adjustments ground coffee, the suitable pore in aperture arranged at the bottom of ground coffee bowl, it is allowed to
Infusion is filtered and flowed out, but the insoluble part in ground coffee, and being stopped by pore to flow out, the coffee of outflow
Solution obtain espresso by container collection.Joined between small flow high pressure heat-exchanger pump and the accumulator by hot water line
Knot, or the small flow high pressure heat-exchanger pump are set directly at the upper piston area in accumulator.Small flow high pressure heat-exchanger pump be hand
Dynamic pump or electrodynamic pump.
Accumulator can be arranged on the inside of hot-water cylinder, accumulator is reduced heat during accumulation of energy and scatter and disappear.Heat in hot-water cylinder
Coolant-temperature gage rationally can be controlled and adjusted by the water temperature control system being made up of cooling-water temperature sensor, temperature controller and electric heater.Hot water
Hot water in tank, available for preparing heat steam.
