Description

A bubble coffee apparatus < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a technique for making a liquid coffee in a micro-nano bubble to make a coffee with a lot of bubbles, more specifically, a cup filled with liquid coffee is set in a suction part of a bubble manufacturing apparatus, A bubble coffee making device that is driven to produce a finished foam coffee filled with bubbles in the other side of the bar.

(0002) The product of the present invention can be made of all kinds of beverages made of water, such as foam drinks. Therefore, it is not limited to coffee only because it is referred to as coffee here, and if it is coffee, it is declared that it is a word implicating "coffee and all drinks". Therefore, the present invention relates to an apparatus for manufacturing a foam in which all beverages are manufactured into foam beverages.

(0003) If you drink fine bubbles in cold coffee or beverage or hot coffee or beverage, you can drink a premium beverage with soft feeling of bubble and sweet flavor and fragrance.

(0004) There are a lot of shops selling specialty coffee and drinks around us, and we use it frequently. Coffee shops and convenience stores sell many types of coffee and beverages in the form of many merchants.

These businesses are constantly trying to sell new flavors of coffee and beverages to maximize sales volume.

(0005) Large coffee merchants such as Starbucks and Energizer, Yiddiyya, and Cafe Vene, which specialize in coffee and beverages, sell Nitro coffee with nitrogen as a new item. Nitro coffee is a high-pressure reservoir made of cold water made of hot coffee made by making a hot put a high-pressure nitrogen into it, and after cooling the open valve of the reservoir to open the high-pressure nitrogen gas into the atmosphere is ejected at this time, It mixes with nitrogen while passing through the nozzle and is made of foam coffee.

(0006) In the case of making nitroform coffee with high pressure nitrogen, hot froth coffee is basically impossible to manufacture, and since high-pressure nitrogen is supplied from a high-pressure nitrogen tank to fill the pressure tank, there is a risk of improved high- It is difficult for the general public to manufacture.

(0007) Milk drinks such as caffe latte, cappuccino, and makiatto, which are generally products that have been bubbled into milk, have been commercially available for a long time, and the skilled barista has steamed the milk surface to produce bubble milk peas do.

In addition, there is a concern about safety accidents caused by hot steam, so that only a skilled person can manufacture it, and this method is also impossible to manufacture cold froth milk.

(0008) Another method is to mix ice and coffee in a blender and rotate it at high speed to mix the ice with the coffee and cool it down. While the air is sucked in from the upper side by the high-speed rotation, There is

(0009) Nitro coffee or milk produced by this method has a certain degree of foam layer, but it is difficult to maintain a foam state for a long time because the amount of foam is remarkably insufficient because it merely mixes air in the beverage, It is not a popular drink because it is flat and fragrant and can not be a breakthrough product.

(0010) In the present invention, it is possible to solve the various difficulties as described above, and it is possible to provide a simple and simple one-touch button operation for cold beverages and hot beverages without using any additional method regardless of beverage type or temperature, I made this invention to make it.

The present invention can make a beverage containing a large amount of regular and uniform bubbles even if it is simply passed through the apparatus in order to make bubbles in coffee or beverage without adding any additives to the coffee in advance or performing additional work, The present invention has been made in view of the above problems, and it is an object of the present invention to provide a safe foam manufacturing apparatus which can be easily manufactured by a general public,

According to another aspect of the present invention, there is provided an apparatus for manufacturing a foamed coffee according to the present invention, wherein a preparation cup to be made of foam is placed in the rear of the apparatus, and a suction pipe And a high-pressure pump for pumping high-pressure liquid is installed inside the apparatus. Here, an outlet for strongly jetting the liquid coffee compressed at high pressure through the fine nozzles to the outside is provided, and a vowel cup is disposed at the lower end thereof.

The compressed air in the liquid coffee sprayed at a high pressure is micro-nano bubbles generated in the coffee in order to have the original volume before being compressed at atmospheric pressure. The present invention uses the characteristics of the micro- Making coffee.

(0014) The inventive foam coffee maker can easily produce a bubbly, sodgy and fragrant frothy drink by using a simple and low-cost device at home or at home.

(0015) Especially, regardless of the type of beverage or the temperature of the beverage, it is possible to manufacture the beverage by simply operating the one-touch button with cold-frothed coffee or cold-frothed beverage, so that the beverage sales professional employs professional technicians for bubble- It is not essential, it can easily enjoy various drinks such as coffee, milk and green tea at home, as foam drinks.

(0016) In specialty shops, various kinds of foam drinks that can be manufactured with this device are diversified, and the sales menu of the business can be diversified, and it will be a good equipment to attract many customers.

(0017) In the case of a convenience store that operates 24 hours, if a large-capacity dispensing device interlocked with this device is sold, it will greatly contribute to sales growth.

(0024) In the present invention, micro-nano bubbles are made into general coffee by using a technique of finely dividing water and air, which are sources of all beverages based on water, and the negative ionization characteristics of the micro- It is designed to produce a soft, bubbly coffee with a lot of fragrant components of coffee in the bubbles.

(0025) A coffee or a drink refers to a coffee or a drink commonly consumed by us, and does not need to be subjected to any other treatment separately for use in the apparatus, and is redefined in more detail.

(0026) Coffee refers to american style coffee for business use, which is a coffee extract (espresso) extracted with steam and high pressure, hot coffee added with hot water, cold coffee added with cold water,

(0027) In addition, hot coffee and cold water added with hot water added to the crude coffee (cold class) solution made by worrying for a long time with cold water,

(0028) Also included is a drop coffee made by putting a chopped coffee bean in a dripper equipped with a paper filter and slowly pouring hot water from above,

(0029) and hot milk sold on the market, cold milk made cold, or a hot milk mixture added an appropriate amount of coffee, a cold cold milk mixture,

(0030) All drinking beverages such as strawberry milk, banana milk, soy milk, green tea, fruit tea, plum juice, other manufactured drinks, rice wine, beer, and small water can be made into bubble drinks. Thus, the term beverage refers to any large, non-dehydrated beverage made on the basis of water

(0031) Here, coffee is specifically described as an embodiment of the method of manufacturing a frothy beverage

(0032) The amount of bubbles made by microbubbles differs depending on the temperature and type of coffee or beverage. This is due to the difference in the solubility of the air depending on the water temperature and also on the number of microparticles in the coffee or beverage. If the number of microparticles is large, a large amount of cation adheres to the microanode bubbles. The layer becomes thick and relatively thin when it is small

 The lower the temperature, the more bubbles are generated and the higher the temperature, the lower the amount of bubbles generated.

(0033) Also, there is a large difference in the amount of micro-nano bubbles generated depending on the amount of air sucked together when the coffee or drink is sucked, so that a variable needle valve having a structure capable of finely controlling the amount of air introduced into the apparatus is suitable.

(0034) The amount of air to be introduced is preferably 2 to 5% of the coffee inflow volume, but since there is usually a difference in flavor depending on the shape of the foam coffee or the taste of each individual, this is not a fixed amount, have. This is usually an experimental value of the air flow when simulated.

The main function of the inventive apparatus for making delicious frothy coffee is also the structure of the nozzle and the spraying function. When the high-pressure gas-liquid mixture is passed through a fine nozzle, it collides with a fine gap of a proper size and is scattered, so that the micro-nano bubbles are well differentiated.

(0036) Therefore, the nozzle part should be capable of finely adjusting the size of the hole according to the pressure of the gas-liquid mixture, the kind thereof, and the temperature thereof, so that the precision variable needle valve type nozzle is preferable.

The product of the present invention has a structure in which two foam generating modules are installed in a case having a plastic outer appearance as shown in a representative figure 100.

This makes it possible to manufacture 102 cups of hot coffee and another 103 cups of cold cupcake,

(0038) Alternatively, it is possible to make a composite froth beverage by using a special portion of 102 for coffee and a special portion for 103 of milk.

(0039) It is also possible to manufacture one module for supplying the home appliance for relatively low price as in 105 of FIG.

(0040) The structure of the basic modules of one spherical shape and two spherical shapes has the same structure as shown in FIG. 1, but differs depending on the number of combinations of modules.

Therefore, it is emphasized that one spherical shape and two spherical shapes are the same concept regardless of the combination of spheres arranged with the same concept of the present invention.

(0041) Inside the apparatus, there is a structure in which a pump and accessories are integrally attached to a support plate made of a galvanized steel plate of a representative figure of 132, and a bubble coffee bar is placed on the front part of the apparatus And the bubble coffee preparation glass is placed on the back side of the device as in the case of the representative 110, thereby reducing the size of the device,

(0042) Coffee large capacity reservoir for large quantity sale of same drink in business

3, which is a large-capacity coffee hot-water supply device 201 of FIG. 3, is disposed at the rear of the apparatus so that the suction port of the apparatus can be directly connected, the mutual connection can be made easy and the installation site can be narrowed. A suitable structure can be used.

(0043) The following is a detailed description of the process of manufacturing the bubble coffee using this device.

First, prepare a cup of about 100ml ~ 150ml of ice cream, place the prepared glass like 110 on the back of the device, and immerse 111 of the aspiration tube into the glass. In general, the amount of coffee in domestic specialty shops is about 100ml ~ 150ml. I can appreciate it.

A representative example of the suction pipe 112 is preferably a stainless pipe or a non-toxic silicone tube, and a filter device is installed at the tip of the suction pipe so as to prevent coffee residue from entering the device. The filter is generally made of stainless steel mesh of about 200 mesh, and is easy to clean. It has a one-touch fitting structure that is easy to remove.

In addition, considering the suction force of the pump, the suction pipe should have an inner diameter of at least 4mm and its structure shall be a one-touch fitting connection structure which is easy to remove.

(0045) and the vowel is located as in the figure 160. Turn the knob of the air inlet needle valve to adjust the number of the dial to 2 and lock the knob.

(0046) is turned until the gap adjustment knob of the 140 nozzle of the representative is not rotated in the negative (-) display direction (clockwise), that point becomes the origin. Thereafter, it rotates about 4 rotations in the (+) counterclockwise direction to adjust the clearance, and it becomes the standard state clearance adjustment.

At this time, while observing the state of the foam to be manufactured, the number of revolutions can be increased or decreased to re-adjust the foam state of the coffee.

In order to produce 200 ml of frothy coffee for about 30 seconds with a 60-watt DC-type gear pump employed in the present apparatus, it is preferable that the nozzle is fixed by about 4 rotations counterclockwise

When the set of preparation coffee cups is completed on the suction side of the apparatus,

Then, when the start button 101 of the representative is pressed, the motor 131 rotates with the power supplied from the power supply unit 133 of the power supply unit, and the coffee is sucked into the pump through the suction pipes 111 and 112 while the pump 130 rotates at high speed Then, through the representative 120 "air valve", a set amount of air is sucked into the pump chamber together with the coffee

At this time, the sucking head of the pump sucking the coffee can suck the coffee irrespective of the position of the dispenser, which is a mass supply device of the raw material.

(0049) The sucked coffee and air are mixed with each other by the high-speed rotation of the pump's dual helical gears, and sequentially compressed. When passing through the representative 140 "nozzle", the pressure is increased to about 2.5 kg / When it is blown into shape, it is scattered and dispersed with a fine water droplet. Looking back at its composition in detail,

2, the high-pressure coffee in the 141 direction is introduced through the pipe 142 and the micro-passage in which the clearance between the nozzle sides 144 is adjusted by the nozzle adjustment knob 143 is adjusted to about 30 Lt; RTI ID = 0.0 > of < / RTI >

(0051) At this time, when a stencil network 145 of approximately 100 meshes is provided at a distance of about 10 to 15 mm from the front surface of the "nozzle", the coffee as a mixture of gas and liquid sprayed from the "nozzle" 145, the coffee and the compressed air are shattered, and the coffee is collected through the 150 housing of Fig. 1 through the entrance of the 107 and falls to the vowel 160 of Fig.

(0052) At this time, the coffee that has fallen into the vowel pool is returned to the original volume of the air particles in the coffee which has been contracted at high pressure, and micro-nano bubbles are produced.

(0053) During high-speed spraying, coffee and air hit the sten mesh at high speed, causing water and air to lose ionic charge due to ionization and become ionized. At this time, the surfaces of the micro nano bubbles are transferred to negative ions so that the same polarity repels each other while floating at a constant distance while floating in water.

(0054) The floating micro-nano bubble FIG. 4 shows that the ion-binding protein 300 of FIG. 4 is ion-bonded to the protein 310 and the lipid fine particle 310 in the coffee, Layer.

(0055) The bubbles that continuously float in the inside rise in the micro-nano size (20 to 100 nm) at a lifting speed of about 2 to 3 mm per minute, and continuously exist in the coffee cup for a long time, To rise above the surface to create a thick foam layer.

More over time, evenly spreading throughout the coffee, the bubbles continue to gather up in buoyancy and accumulate in the coffee cup, bubbles rise up to the bottom and the coffee remains.

(0056) We drink the coffee at the top of the coffee cup and then pour the remaining coffee again. Then we move back to the static force of static microbubbles in the room without motion, You will be able to drink coffee.

(0057) There are many ingredients in the coffee bean, but it is especially fat that gives off the flavor and aroma. According to the literature, the fat is usually found in about 12 to 16 percent of the coffee.

Fat microparticles in coffee are attracted to the foam's anion and attached to the foam surface to apply the coffee surface. There is a big difference in the area of contact with our tongue when this fat is just dissolved in water and in the coffee, and its surface when it comes into contact with our tongue, as it is flocculated on the foam surface.

(0058) A simple comparison of the volume and surface area based on 20μ bubbles is 4/3 × 3.14 × (0.02) ^ 3 = 0.0000335 at the original volume formula = 4 / 3πr ^ 3 and the surface area of bubbles = 4πr ^ 2 to 0.005 and 0.005 / 0.0000335 150, so that the surface area is about 150 times larger than the volume.

(0059) This is because the area of the bubble that touches the tongue is widened by drinking the bubbles rather than just drinking the coffee water, so that the area where the taste is felt becomes more wider becomes relatively wider, so that we have a feeling of increased flavor.

We did not add any additives that would make the coffee taste like a coffee.

It is also a kind of fat that is perceived as a flavor when it is inhaled into our nose by vaporizing from the water surface of coffee.

(0060) In order for the liquid to vaporize, it is essential to raise the surface temperature of the liquid to weaken the surface tension to activate the evaporation of the liquid. However, the surface area is widened to increase the amount of air to be vaporized, Do. Especially in the case of cold coffee, if the temperature is between 5 ° and 8 °, it is difficult to vaporize in ordinary coffee, but in case of frothy coffee, it is easy to vaporize, so we can enjoy steamy coffee aroma in the frozen coffee.

(0061) If you make coffee with micro-nano bubble bubbles, you can make a coffee that is very soft, fragrant and flavorful with a cup of coffee.

(0062) However, coffee, which is produced by simply putting fine air into the air like a generally manufactured nitro coffee, is so thin that the foam layer is lifted up to the surface, so that the amount of foam is considerably short and the taste is also soft. However, Because there is no condensation collecting, it does not complain or smell much and is plain.

(0063) When the amount of coffee set in the cup 160 of the representative cup is full, if the operation is stopped by pressing the button 101, the operation of the pump is stopped, the operation of the foam generator is stopped and the bubbling operation is completed once.

(0064) In the internal cleaning of the present invention, water is prepared in 110 preparations of a representative figure or larger, and water is poured into the apparatus by pouring about 60 ° of warm water,

Repeat this process a few times to clean the inside.

(0065) After using the beverage, such as milk, which has a lot of fat, you can repeat the cleaning process with the appropriate dilution with the edible equipment cleanser.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the basic concept thereof. It belongs to the scope.
