Abstract

PROBLEM TO BE SOLVED: To obtain a cold coffee beverage capable of adjusting concentration of coffee while drinking without becoming watery even with the passage of time. SOLUTION: This coffee beverage is obtained by mixing many coffee ice lamps 2 obtained by freezing a concentrated coffee extract with liquid cow milk 4. Since the coffee beverage is drunk while dissolving coffee ice lamps 2, coffee can be tasted while adjusting to desired concentration and the coffee does not become watery as the conventional ice coffee becomes watery with the passage of time. It is not required to add sweetener such as syrup later because a coffee extract in which sweetener is mixed is frozen in order to form coffee ice lamps. Further, coffee ice lamps 2 are not made to float when cow milk 4 is charged to coffee ice lamps 2 by keeping the specific gravity of coffee ice lamps 2 so as to be larger than the specific gravity of cow milk 4. Therefore, the coffee beverage is readily miscible and readily drinkable.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cold coffee beverage such as iced coffee which is mainly consumed in summer.

[0002]

2. Description of the Related Art Conventionally, ice coffee sold at restaurants or coffee shops contains ice in a coffee extract, and a customer adds syrup or fresh (concentrated milk) to the coffee extract according to his / her preference. Drinking.

There is a so-called ice cafe ole as a coffee in which an appropriate amount of milk and a coffee extract are mixed and ice is added thereto.

[0004]

In any case of iced coffee, if too much syrup or fresh is added first, the sweetness and the density cannot be adjusted thereafter, and the ice becomes watery as the ice melts. Even in such a case, it is difficult to adjust the density.

[0005]

OBJECTS OF THE INVENTION It is an object of the present invention to provide a cold coffee beverage that does not become watery over time and that allows the coffee consistency to be adjusted while drinking.

[0006]

In order to achieve the above object, the invention according to claim 1 of the present application is to mix a large number of coffee ice blocks obtained by freezing a concentrated coffee extract and liquid milk to mix the ice temperature. It is close to coffee drinks.

According to a second aspect of the present invention, in the cold and hot coffee beverage according to the first aspect, the mixed coffee extract mixed with the sweetener is frozen to form a coffee ice block.

The invention according to claim 3 is characterized in that the specific gravity of the coffee ice block is made larger than the specific gravity of the milk so that the coffee ice block does not float.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1 showing a coffee beverage to which the present invention is applied, one glass cup 1 contains a large number of frozen coffee ice blocks 2, and the other cup 3 generally contains coffee. Liquid milk 4 in the same amount as ice block 2
Is inserted. In a restaurant or the like, as shown in FIG. 1, coffee ice chunks 2 and milk 4 are provided separately to customers,
The customer puts milk 4 into the coffee ice chunk 2 in a desired amount, stirs it with a straw or a stirring rod to melt the coffee ice chunk 2 to a desired concentration, and drinks the melted coffee formed in the cup 1 by the straw.

[0010] As the coffee ice block 2, roasted coffee beans are roasted and ground to obtain coffee powder, which is extracted with water or hot water to form a coffee extract, and a frozen coffee extract is used. The shape is crushed into a random fractured shape, and the size is from 5 mm to about 2 cm or about 3 cm, and various sizes are mixed. Of course, the shape of the coffee ice block 2 can be a uniform shape, for example, a large or small sphere, a rectangular parallelepiped or a cube.

The coffee extract to be frozen may be a liquid containing only coffee components, but is produced by freezing a coffee extract containing a sweetener and a coloring agent such as caramel. You can also.

The milk 4 is a liquid, but its temperature is arbitrary. Normally, cold milk at 4 ° C. to 10 ° C. is good.
Warm milk at room temperature of about 15 ° C to 20 ° C may be used.

The specific gravity of the coffee ice block 2 is larger than the specific gravity of the milk 4. Therefore, when the milk 4 is put in the coffee ice block 2, the coffee ice block 2 does not float.
Therefore, it is easy to mix and drink.

An example of a method for producing the ice coffee mass 2 will be described. For example, when a concentrated coffee extract is intensively manufactured at a factory, frozen, and crushed, shipped to each restaurant or coffee shop, etc., and milk and coffee ice blocks are mixed in each store to make a coffee beverage Will be described.

(1) In a central manufacturing plant, green coffee beans are roasted and ground to fine coffee powder, and then extracted with hot or cold water to produce a concentrated coffee extract. (2) The concentrated coffee extract and the caramel, a sweetener and a colorant, are mixed and dissolved in the dissolving water to prepare a mixed coffee extract, which is preheated to, for example, 60 ° C. and filtered. (3) Sterilize by heating at 85 ° C. for 15 seconds. (4) Cool to 4 ° C in the aging tank. (5) Fill the mixed coffee extract into an ice tube for freezing,
Freeze at -30 ° C with a freezer. (6) Store frozen in a freezer at −25 ° C. or lower, for example, for 8 hours or more. (7) Take out with a freezer, crush into ice blocks of various sizes with a crusher, and remove the powder portion with a sieve. (8) It is conveyed to a filling machine by a screw conveyor or the like, and filled into a carry-out container from the filling machine. At the time of filling, it is frozen by spraying liquid nitrogen. (9) Using a metal detector and a weight checker, inspect the foreign matter in the transport container for contamination or the weight thereof, and pack the unloading container in a box and temporarily store it in a freezer. (10) Ship to a predetermined restaurant or the like as appropriate. (11) At a restaurant, as shown in FIG. 1, a cup 1 containing a coffee ice block 2 of a coffee extract and a cup 3 containing milk 4 are served to the customer, and the customer can supply an amount of milk 4 according to their preference. The coffee is put into the cup 1 containing the ice mass 2 and melted to an appropriate concentration to adjust the concentration and drink.

[0016]

[Other Embodiments] The invention according to claims 1 and 2 can be applied even when the specific gravity of the iced coffee mass 2 is smaller than the specific gravity of the milk 4.

[0017]

As described above, according to the present invention,
A coffee beverage is prepared by mixing a large number of coffee ice blocks 2 obtained by freezing a concentrated coffee extract and liquid milk 4;
Since the coffee ice chunk 2 is drunk while being melted, it is possible to taste the cold coffee while adjusting the density to a desired level, and it does not become watery like conventional iced coffee even after a long time.

As in the second aspect of the present invention, when the coffee extract mixed with the sweetener is frozen to form the coffee ice block 2, it is not necessary to add a sweetener such as syrup later.

If the specific gravity of the iced coffee mass 2 is made larger than the specific gravity of the milk 4 as in the third aspect of the present invention,
When the milk 4 is put in the coffee ice block 2, the coffee ice block 2 does not float, so that it is easy to mix and drink.
