Description

TECHNICAL FIELD The present invention relates to an all-in-one portable espresso extracting machine that can grind coffee beans,

More particularly, the present invention relates to a portable espresso extracting method, and more particularly, to a portable espresso extracting method, and more particularly, to a portable espresso extracting method, and more particularly, to a portable espresso extracting method which comprises a grinding process of grinding a bean curd by a grinding blade in the apparatus, The present invention relates to an integral type portable espresso capable of pulverizing a bean that enables a process of extracting a finished espresso and a process of compressing an espresso by converting a single-shaft rotary motion into a vertical reciprocating process.

Demand for high-end coffee, which is sold in professional coffee shops rather than traditional instant coffee, is gradually increasing as the demand for coffee increases as society becomes more sophisticated.

Espresso is the most basic coffee for enjoying various kinds of coffee, and it is possible to manufacture all coffee based on espresso.

However, in order to produce espresso, a process of grinding bean powder, a taming process of flattening the beans made of powder, a process of extracting using water at a temperature of 90 to 100 ° C and a pressure of 7 to 9 atm in a tampered coffee So there is limited space to enjoy it if you do not have an espresso extraction machine.

To solve this problem, the portable espresso extractor has to use already prepared coffee in order to enjoy the coffee. Also, if you want to enjoy the coffee with fresh beans after tampering, And the compression method by electricity, nitrogen and air compression is required to provide additional energy consumption in order to supply the pressure required to compress the espresso and the inconvenience of the procedure in which a separate tamper for the tampering must be prepared. And the purchase of a secondary product leads to a problem that the user feels uncomfortable.

The present invention relates to a grinding process for grinding a bean by a grinding blade in a mechanism by a mechanical mechanism by a force without using the above and electricity, a tampering process for flattening the grinded bean flour, An object of the present invention is to provide an integrated portable espresso extractor capable of pulverizing a bean that enables a process of compressing espresso by converting it into a reciprocating motion and extracting the extracted espresso.

In addition, the present invention simplifies the espresso extraction process and makes it portable so that consumers can extract espresso without being restricted by the place, thereby making it possible to grind coffee beans in an integrated form capable of satisfying consumers' Another objective is to provide a portable espresso extractor.

In order to accomplish the above object, the present invention provides a grinder unit capable of grinding a bean curd using a rotating force while fixing a shaft in an apparatus, and the outer shaft is used in conjunction with a tamper and a pressure unit. However, A pressure regulating part for extracting the espresso by opening the extraction port when the pressure in the cylinder becomes 8 atm or more, Is achieved by an insulated cup which enables the hot espresso to be kept warm.

The present invention makes it possible to simplify the process of making espresso by making the compression pressure necessary to make the espresso simply through manpower without using an additional device including an electric device and to perform the grinding, By making it possible to use a single device, it is possible to facilitate access to the use of coffee consumers and to increase the usability so that consumers can conveniently enjoy various coffees in any place.

In addition, the present invention facilitates the accessibility of consumers who desire to manufacture espresso, thereby broadening the range of existing choices for drinking espresso through most coffee shops, .

The present invention is capable of preparing espresso on the all-in-one portable espresso extractor capable of producing the espresso through a mechanical mechanism using the force from the portable espresso extraction leads that holds water that can produce coffee beans and espresso unit A crushing unit capable of crushing the beans contained in the present invention, a compression unit 1 for making the pressing process of the espresso through the actual pressing process, and cylinders 7 and 8 capable of actually entering the crushed coffee and water .

The lid portion is a trapezoidal cylinder shape located at the top of the present invention, and includes a cup and an injection hole into which water can enter. The lid part includes a function of opening and closing the injection hole in accordance with the use and non-use.

Grinding unit are separated by a large grinding rotary section 2 and is fixed from the inside to the invention grinding base 5, 6 which can be operated directly rotated by hand in the present invention, the grinding rotation unit (2) is in the middle The crushing rotary part (2) includes an outer blade (6) capable of crushing a bean, and the crusher parts (5) and (6) have an inverted trapezoidal shape And an inner blade (5) capable of crushing the beans by engaging with the outer blade (6) of the pulverizing and rotating part on the outer surface in the form of a cylinder.

The outer diameter of the outer blade 6 and the inner blade 6 is set to be the widest at the uppermost portion of the pulverizing rotary portion 2 and the narrowest at the lowest portion in accordance with the outer shape of the pulverizing base portions 5, (5) is narrowed downward as it goes downward, so that the grain size is further reduced as the bean is lowered by gravity after being ground.

Compressing the base (1) comprises a cylinder unit (7, 8) stacked on to practice the tamping process that evenly compacted ground coffee, and at tamper 9 and the tamping process can be squeezed tightly the inside of the compression cylinder during espresso A spring 10 capable of returning the tamper descended in the vertical direction back to its original position, and compression rotary parts 11 and 12 and a compression cylinder 4 for a pressing process.

The spring 10 has a tubular shape and is connected to the lower surface of the lid portion and the upper surface of the lower end portion of the tamper to prevent arbitrary movement and has a modulus of elasticity capable of returning to its original position after the tamping process, The long cylinder portion of the upper portion is located on the inner side of the spring.
