Description

Design printing device for coffee {design printing device for coffee}

The present invention relates to a design printing device for coffee that prints a predetermined design pattern on the liquid surface of coffee, and more particularly, to a coffee design printing device capable of automatically expressing design patterns on the liquid surface of coffee with cream of various colors. It's about the device.

Recently, it is common to feel that interest in coffee beverages has increased significantly. It has become common to see people carrying and drinking coffee beverages on the street, and a coffee mania layer has been formed to exchange information on the taste and aroma of various coffees through the Internet, and baristas who professionally make coffee beverages There are also educational institutions that train baristas. In addition, it can be seen that the general public's interest in coffee beverages has greatly increased as cultural events for various coffee beverages such as coffee and coffee manufacturing equipment exhibitions are held and barista competitions are held.

Recently, latte art is popular, which provides not only the taste of coffee drinkers but also visual pleasure by drawing design patterns such as patterns, pictures, letters, etc. on the surface of coffee with milk foam.

Latte art can draw various design patterns on coffee through pre-pouring, which pours milk foam over coffee, powder art, which sprinkles powder on milk foam, and etching that expresses details using a thin and sharp etching pen. there is.

However, since these conventional latte art are entirely handcrafted by baristas, it was difficult to express design patterns of the same shape in large quantities with a lot of time and effort.

Accordingly, Registered Patent No. 10-1446802 discloses a raw material container having an inlet and an outlet, an opening/closing unit that discharges raw material from the raw material container downward through the outlet according to an operator's operation, and a material coupled to the outlet side of the raw material container and introduced when the opening/closing unit is opened. A latte art pattern having a pattern forming unit in which a negative or embossed pattern is perforated to discharge downward in the form of a pattern or a picture, and a raw material dispersion unit located between the raw material container and the pattern forming unit to evenly disperse the raw materials input into the pattern forming unit A latte art pattern molding machine has been published so that ordinary people can provide latte art drinks that can provide visual pleasure as well as taste in daily life through the molding machine.

However, this latte art pattern forming machine was not fully automatic, so the user was not satisfied with the level of convenience, and the design expression was not at a delicate and precise level, so the quality was much lower than that of latte art made by baristas themselves. There was a problem.

In addition, Patent Registration No. 10-1862521 discloses a coaster on which a cup is seated, a printing unit for supplying milk foam to the cup and forming an image on the supplied milk foam, and the printing unit for x-axis, y-axis, and z-axis Disclosed is a latte art printer capable of inputting and printing not only an input image but also a new image in real time, including a transfer unit that moves in an axial direction and a control unit that controls operations of the printing unit and the transfer unit.

However, these latte art printers simply supply milk foam and form an image on the milk foam, so it is difficult to express colorful colors and detailed and precise design patterns, and the steam generating unit generates steam milk. However, there was a problem in that a lot of power consumption was required to supply steam milk, and there was also a sanitary problem because the nozzle of the printing part was not properly cleaned.

Therefore, the control unit 70 combines and attaches a plurality of cream printing plates 220' to the magnet attachment plate 215 based on the set design image, thereby forming the shape of the design engraved portion 222a formed on the cream printing plate 220'. It can be configured to form a specific design pattern by combination.

In this way, the plurality of printing plates 220' are attached to the magnet attachment plate 215 by magnetic force so that the shape combination of the design engraved part 222a is made, and then the cream application unit 230 is controlled by the control unit 70. Cream can be applied to the design engraved portion 222 of the cream printing plate 220' attached to the magnetic attachment plate 215 by moving the cream printing means 20-2 to the side, and in this state, the position transfer unit ( 40) to drive and stamp the cream printing plate 220' on the coffee liquid surface of the coffee cup c, and the cream applied to the design engraved portion 222 of the cream printing plate 220' is transferred onto the coffee liquid surface. This allows the design pattern to be formed in a stamp method (see FIG. 14).

In the above, the present invention has been shown and described in relation to preferred embodiments for illustrating the principles of the present invention, but the present invention is not limited to the configuration and operation as shown and described. Rather, those skilled in the art will appreciate that many changes and modifications to the present invention can be made without departing from the spirit and scope of the appended claims. Accordingly, all such appropriate changes and modifications and equivalents should be regarded as belonging to the scope of the present invention.
