Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

More particularly, the present invention relates to an apparatus for producing a raw-liquid-supply-type coffee, and more particularly, To a supply type coffee making apparatus.

Generally, coffee is a favorite food enjoyed by the general public, and water is added to the crushed powdered coffee beans to drink the liquid coffee. In recent years, instant coffee that can be used to drink coffee by simply producing powdery coffee raw material and diluting it with water has been developed and widely used.

This kind of powdered coffee material is prepared by diluting with water so that coffee can be taken. Therefore, coffee powder and water, which are controlled in the amount of supply, can be supplied automatically to produce a coffee to be consumed. A desired concentration of coffee can be produced.

However, powdered instant coffee is difficult to maintain the original flavor and aroma of coffee during the process of processing a large amount of coffee beans, and since a large amount of processed coffee beans is used, a single type of bean that meets the general public's taste is used And it was difficult to produce coffee raw materials having various flavors and aromas.

In addition, recently, a coffee shop that produces coffee with various flavors and aromas according to the user's taste has been established, and the taste and taste of general consumers have become complicated, and various types of coffee raw materials are being developed.

In this way, a crude coffee raw material in the form of a raw liquid which is diluted in warm water while maintaining various flavors and aromas among coffee raw materials has been developed and widely used. However, coffee raw material in the form of undiluted powder was in a liquid state different from powder, and thus it was difficult to automatically supply it to a conventional powder feeder. Accordingly, an apparatus for producing coffee by feeding a liquid coffee stock solution while controlling the supply amount by an operation has been developed.

The prior art raw-liquid-supply-type coffee manufacturing apparatus is installed in a supply portion of a tank in which a coffee stock solution is stored, and is provided to be diluted with hot water by supplying the coffee stock solution with a free fall pressure through a supply pipe by electronic operation.

[0004] However, in the conventional liquid supply device for producing coffee, the coffee stock solution is supplied in free fall. The free fall pressure is greatly changed according to the atmospheric pressure, . That is, since the coffee stock solution has viscosity, the supply amount is insufficient when supplied at a low pressure, and is excessively supplied when supplied at a high pressure. In addition, if the supply amount of the coffee stock solution is large, the mass of the coffee stock is large and the free fall speed is increased. If the storage amount is decreased by the continuous supply, the free fall rate is continuously decreased in proportion thereto, there was.

In the prior art liquid supply type coffee manufacturing apparatus, since the coffee liquid having viscosity is supplied through the supply pipe, the coffee liquid may flow into the inside of the supply pipe while being contaminated, There is a problem in that the inside needs to be cleaned.

Accordingly, in recent years, a device has been disclosed and used in which a pump is provided so as to supply a coffee stock solution with a constant pressure without a change in pressure, and a coffee stock solution is supplied by the pressure of the pump.

However, since the pump has to be installed at a position where the coffee stock solution is supplied, the apparatus becomes complicated and the volume of the apparatus is increased.

In addition, the coffee stock solution is instantaneously operated only at the moment of dilution of the coffee, and after the supply is maintained again, the pump is operated irregularly as the pump is kept stationary. And the supply amount of the coffee stock solution is not constant.

SUMMARY OF THE INVENTION The present invention has been developed in order to solve the problems described above, and it is an object of the present invention to provide a method and apparatus for supplying coffee stock solution by supplying a coffee stock solution while maintaining a constant supply amount by using hot water supply pressure, And to provide a raw-liquid-supply-type coffee manufacturing apparatus which can improve the ease of supply and accuracy by controlling the supply amount.
