1, a method for manufacturing a health tea according to an embodiment of the present invention is a method for manufacturing a health tea comprising the steps of applying a bubble water to at least one tea material selected from flowers, leaves, stems, A step of applying an herbicide fermentation liquid to the tea material washed in the bubble water washing step, and a step of drying the tea material coated with the herbal fermentation liquid, A first drying step of reducing the moisture content of the tea material, a first step of putting the tea material dried in the first drying step into a tumbling container and heating and kneading the mixture, And a tea drying step.

The production method of the health tea of the present invention will be described step by step.

1. Bubble water washing step

First, bubble water is added to at least one of tea materials selected from flowers, leaves, stems, and roots of the plant to wash the tea material.

As the material of tea that can be used in the present invention, the flower of the plant is leaf, stem, root. Any one of flowers, leaves, stems, and roots can be used alone or as a mixture of two or more. There is no particular restriction as long as it is an applicable plant and does not have toxicity to human body. For example, various plants such as chrysanthemum, herb, mugwort, omija, 칡, pine, azalea, fruit, vegetables can be applied as well as green tea leaves which are common tea materials.

When the tea material is prepared, it is washed to remove harmful substances such as soil, dust and various foreign substances, heavy metals and pesticides on the surface of the tea material.

When washing is carried out with a conventional water washing, areas such as flowers and leaves are fragile and prone to scratches or damage. Therefore, in the present invention, the number of bubbles is used as a method of washing the car material without damaging fragile parts such as flowers and leaves.

The number of bubbles means water in which bubbles are generated. Preferably, the bubbles are ultrafine bubbles having a size of nano or micro level. Microbubbles having a size of nano- or micro-level, which are difficult to be visually recognized, having a size of 0.01 to 50 탆, that is, 50 탆 or less, have high washing and sterilization effects.

Unlike ordinary bubbles, nano- or micro-level microbubbles rise at a very slow rate and disappear in water. At this time, at the extinction of bubbles, shock waves of 400 km / hr including ultrasonic waves of about 40 KHz, high sound pressure of 140 db, and instantaneous high temperature of 4000 to 6000 ° C are generated. Such ultra-micro bubbles will kill harmful bacteria and decompose various organic substances and foreign substances. It also breaks clusters of contaminated water and serves to supply oxygen at the same time, increasing the amount of dissolved oxygen.

As an example of the cleaning method using the above-mentioned bubble water, if the bubble water is continuously supplied to the cleaning tank after the tea material is supplied to the tubular cleaning tank, the bubbles in the bubble water will disappear and the harmful bacteria in the tea material will be killed, Decompose. In addition, when air bubbles float, foreign substances such as various dusts float together on the water surface to remove foreign matter.

On the other hand, the number of bubbles can be obtained by using a conventional bubble number generator, but the number of bubbles generated by using the bubble number generator shown in Fig. 2 is preferably used. A detailed description of the bubble number generator and the bubble number generating method will be described later.

Bubble water After washing, the tea material is removed from the washing tank and placed on a net, a sieve, or a basket to remove water.

2. Preparation step of herbal fermentation broth

Next, a herbal fermentation liquid to be applied to the washed tea material is prepared.

The herbal fermentation liquid means fermented herb. Plants can be used as herbal medicines for various medicinal plants. For example, herbs such as gold, white tiger bloom, livelihood, jinbum, lucifer, minjungmyeong, purpose, ganghwam, mangrove, guppycho, gypsum, , Moxibustion, dermis, creation, hongsam, fiction, safflower, ogapi, gosam, white paper, dasoo, hwanggi, mold, , Loner, passerby, exorcism, sorcerer, crust, nutrition, windshield, blue box, omija, licorice, phoenix, boredom, The herb may be used singly or in combination of two or more.

A process for producing a fermentation broth by using the above-mentioned herb, comprising the steps of washing the herb by adding water to the bubbles, adding the washed herb and bubble water to the fermenter, adding the sugar and the fermentation strain to the fermentation, And then filtering the fermented fermented product to obtain the herbal fermentation broth.

The process of washing the herb with foaming water is the same as the washing process of the above-mentioned materials, so a detailed explanation is omitted. The washed herb is put into a fermentation vessel such as a jar for fermentation. Before the washed herb is put into the fermentation vessel, the fermentation vessel is washed with bubbling water and the washing water is introduced into the fermentation vessel. Then, the herb which has been washed at the same volume ratio as the washing water is put into the fermentation vessel. By using the number of bubbles in the fermentation process as described above, it is possible to prevent the fermentation of the fermented product and to promote the fermentation, together with the sterilizing effect of the fermentation vessel.

After the herb is added, the sugar and the fermentation strain are added and fermented at 20 to 30 DEG C for 1 to 3 months. Sugar can be used as a sugar. The fermenting bacteria were mainly Bacillus subtilis subtilis ), Aspergillus oryzae , Aspergillus niger can be used. 20 to 60 parts by weight per 100 parts by weight of the mixture of the cell count and the herb and 0.01 to 0.5 part by weight of the fermentation strain may be put into a fermentation vessel and fermented.

During the fermentation period of 1 to 3 months, bubble water is injected in the middle of the pot. The bubble water may be injected one to three times during the entire fermentation period. The number of bubbles injected during fermentation increases the amount of dissolved oxygen and promotes the activity of microorganisms.

When the fermentation is completed, the fermented material is filtered using a sieve. The remaining solid content can be removed through filtration and a liquid herbal fermentation broth can be produced.

3. Application step

When the herbal fermentation liquid is prepared, the herbal fermentation liquid is applied to the tea material washed in the washing step, and the herbal fermentation liquid is coated on the surface of the tea material.

An atomizer can be used as a coating method. Use a sprayer to spray the herbal fermentation liquid thoroughly throughout the tea material so that the herb fermentation liquid can be evenly applied to the surface of the tea material. The herb fermentation liquid applied on the surface of the tea material adds the herb flavor to the inherent flavor of the tea material. In addition, the herbal fermentation broth is beneficial to health because it contains valuable active ingredients produced by microorganisms during fermentation.

4. Primary drying step

A primary drying process is performed in which a herbal fermentation liquid is applied to the tea material, and then the ingredients of the herbal fermentation liquid are dried so as to be permeated or adhered to the surface of the tea material. Wind can be applied to tea material for drying. It is preferable to apply a natural or warm air at 20 to 40 DEG C which is relatively low temperature rather than hot wind. The primary drying process reduces the water content of the tea material primarily and allows the ingredients of the herb fermentation liquid to penetrate or adhere to the surface of the tea material.

Step 5

The tea material dried in the primary drying step is put into a softening container and then heated and kneaded.

The chewing process can be performed before the virtue treatment. The chelating process is a process of breaking the enzyme contained in the tea material to maintain color and to enhance flavor and aroma, at 150 to 250 ° C. For example, the tea material is put in a pot heated to 150 to 250 ° C, and then the tea material is put in a pot and cooled down repeatedly for 4 to 6 minutes.

Handling can be either manual or automated for mass production. As an example of manual work, the tea material is put into a pot heated to 100 to 150 ° C, and then turned upside down for 5 to 15 minutes.

In addition, a conventional silencer having an internal stirrer can be used in an automated manner. In this case, the heating temperature, stirring time and the like are controlled by the controller. The operator inserts the tea material into the tumbler and operates the tumbler, and after finishing the tumbler, the tea material is taken out and cooled.

6. Secondary drying step

After finishing, the secondary material is cooled and dried.

Place the finished tea material on the seat and spread out and cool. The cooling process can be carried out by leaving the tea material at room temperature in the unfolded state, or by airing using a blower or the like.

It is a matter of course that the health tea produced in this way can be packaged through a packaging step of wrapping in a tea bag or a conventional packaging container as shown in FIG.

Hereinafter, an example of a health care apparatus for performing the above-described health care method will be described.

The health tea producing apparatus of the present invention mainly includes a bubble water generator, a washing unit, a coating unit, a drying unit, and a tilting unit.

The number of bubbles required for the washing of the tea material and the manufacturing process of the herbal fermentation liquid is supplied from the bubble water generator. The bubble number generator is shown in FIGS. 3 and 4. FIG.

3 and 4, the bubble water generator includes a water storage tank 10, a bubble generating unit, a pump 30, first and second connecting pipes 11 and 12, 50), and a circulation pipe (15).

The water storage tank 10 has a cylindrical structure in which a storage space is provided so that a predetermined amount of water can be stored therein. A first connection pipe (11) is installed below the water storage tank (10). The first connection pipe (11) is provided with a valve (13) for opening and closing the flow path.

The bubble generating unit is for generating bubbles primarily in the water stored in the water storage tank 10, and comprises a water supply pipe 20 and a water supply unit.

The water supply pipe (20) is installed at a position spaced upward from the water surface of the water storage tank (10). The water supply pipe (20) is installed so that the discharge port through which the water is sprayed faces the water surface. The water supply part supplies water to the water supply pipe (20). A raw water storage tank connected to the water supply pipe 20 and a raw water supply pump installed in the water supply pipe 20 for pumping the water stored in the raw water storage tank to the water supply pipe.

It goes without saying that the water supply pipe 20 is connected to a conventional water supply pipe so that tap water can be directly introduced into the water storage tank.

The water sprayed downward through the discharge port of the water supply pipe 20 collides with the water surface of the water stored in the water storage tank 10. [ In the course of the collision, air and water outside the surface of the water mix together to form bubbles. The bubbles generated primarily in the water storage tank 10 are large in volume and can be easily visually confirmed.

The number of bubbles generated in the water storage tank 10 is sucked into the pump 30 through the first connection pipe 11. The first connection pipe (11) is connected to the suction port of the pump (30).

A centrifugal pump is used as the pump 30 applied to the present invention. The centrifugal pump is provided with a rotating impeller inside the casing to suck and discharge the bubble water from the water storage tank (10). At this time, the bubbles in the bubbles water sucked into the pump 30 are finely divided by the rotation of the impeller inside the pump 30, and become fine bubbles. The generated bubbles are ultrafine bubbles having a size of nano level which is not more than 50 탆, that is, 0.01 to 50 탆 in size and which can not be visually recognized. The bubble water mixed with the ultrafine bubbles is discharged to the second connection pipe (12) through the discharge port of the pump (30).

A second connection pipe (12) is provided at a discharge port of the pump (30). A pressure holding pressure tank 40 may be provided on the discharge side of the pump 30. The second connection pipe (12) is connected to the washing tank (100) for washing the car material.

The throttling portion 50 is provided in the second connection pipe 12 for passing the bubble water discharged from the pump 30 through the throttling flow passage 63 to increase the generation of bubbles. A large number of bubbles are generated in the course of the pressure and the velocity varying as the bubble water discharged from the pump 30 passes through the throttling channel 63 which is narrowed in cross section and then spreads again.

The throttle portion 50 includes a throttle pipe 51 in which a throttle channel 63 is formed, flanges 53 and 55 provided on both sides of the throttle pipe 51, (70).

A second connection pipe 12 is connected to both flanges 53 and 55 of the throttle pipe 51. The porous body 70 has a structure in which a large number of voids are formed so that the bubbles in the bubble water passing through the diaphragm flow path 63 can be further finely split. As the porous body 70, minerals such as volcanic stone and zeolite in which fine pores are formed in an anhydrous manner can be used. In addition, a sponge having a porous body and a sponge having a water-repellent structure can be used. The number of bubbles passing through the porous article 70 is formed by numerous voids that are finely dispersed by numerous voids formed in the porous article 70, and these flows can be turbulent to improve contact efficiency and dissolution efficiency.

The circulation pipe (15) branches off from the second connection pipe (12) and extends into the water storage tank (10). The circulation pipe (15) is provided with a valve (17) capable of opening and closing the flow path. Circulates a part of the bubble water that has passed through the throttle portion (50) through the circulation pipe (15) to the water storage tank (10). About 0.01 to 0.1% by volume of water in the foam water is circulated to the water storage tank 10, and the rest is introduced into the washing tank 100.

The bubble water flowing into the water storage tank (10) by the circulation pipe (15) is mixed with the bubble water of the water storage tank (10). A larger amount of fine bubbles can be generated in the water storage tank 10 by the number of bubbles circulated to the water storage tank 10, so that the bubble generation efficiency can be greatly increased as a whole.

On the other hand, in order to further facilitate mixing of water and air, the bubble generating unit may have the structure shown in Fig.

5, the bubble generating unit includes a mixing housing 80 installed at a position spaced upward from the water surface, a water supply pipe 20 extending through the upper surface of the mixing housing 80 and extending into the mixing housing 80, A water supply part (not shown) connected to the water supply pipe 20 to supply water to the water supply pipe 20, a discharge pipe 85 installed on the bottom surface of the mixing housing 80, A liner 90 inserted and installed, and a turbulent flow piece 95 protruding from the inside of the liner 90.

The mixing housing (80) has a hollow cylindrical shape. A through hole is formed in the lower surface of the mixing housing 80, and a spray pipe 85 is connected to the through hole. The jetting pipe (85) is installed in the mixing housing (80) so that the discharge port faces the water surface.

The water supply pipe (20) and the circulation pipe (15) are connected to the mixing housing (80). The water supply pipe (20) extends through the upper surface of the mixing housing (80) and into the mixing housing (80). Thus, the end of the water supply pipe 20 is exposed to the inside of the mixing housing 80.

The circulation pipe (15) extends through the side surface of the mixing housing (80) and into the mixing housing (80). Therefore, the end of the circulation pipe 15 is exposed to the inside of the mixing housing 80. The circulation pipe (15) is branched from the second connection pipe connected to the discharge port of the pump.

The water supply pipe 20 and the circulation pipe 15 form a right angle within the mixing housing 80 so that the water supplied through the water supply pipe 20 and the bubble water supplied through the circulation pipe 15 may collide with each other. The water supplied through the water supply pipe 20 and the bubble water supplied through the circulation pipe 15 collide with each other inside the mixing housing, so that water and bubbles can be easily mixed. The water supplied through the water supply pipe 20 and the bubble water supplied through the circulation pipe 15 are discharged into the water storage tank through the injection pipe 85 in a mixed state.

The liner 90 provided inside the jetting pipe 85 is formed with a conical flow path 93 that progressively narrows downward. The outer diameter of the liner 90 is the same in the upper and lower portions, but the inner diameter is narrower than the upper portion.

When the fluid discharged to the jetting pipe (85) passes through the conical flow path (93), the flow rate becomes faster and the pressure becomes lower, so that the water and the gas are strongly mixed. Then, the moment the gas is discharged to the outside through the discharge port of the injection pipe 85, the flow rate is slowed down and the pressure is increased so that the gas is pressurized and dissolved in the water. A turbulent flow 95 is formed on the inner side of the liner 90 such that turbulence is generated in the water passing through the flow path of the liner 90 and the water and the gas are continuously brought into contact with each other, Improves efficiency.

As described above, the bubble number generator according to the present invention can easily generate ultrafine bubbles having a nano or micro level size without a high-pressure air compressor.

First, the water supplied from the outside is supplied to the interior of the water storage tank 10 through the water supply pipe 20. In this process, the water discharged through the discharge port of the water supply pipe (20) collides with the water surface of the water stored in the water storage tank (10) to generate bubbles primarily.

Next, the bubbles generated in the water bubbles in the water storage tank 10 are finely divided. For this purpose, the bubble water is sucked from the water storage tank 10 through the pump 30 connected to the water storage tank 10 and the first connection pipe 11 and discharged to the second connection pipe 12. In this process, the bubbles in the bubble water sucked into the pump 30 are finely divided by the rotation of the impeller inside the pump 30, and become fine bubbles. Further, the number of bubbles discharged from the pump 30 increases as the pressure and the velocity change while passing through the throttling portion.

Next, a part of the bubble water that has passed through the throttle portion 50 is circulated to the water storage tank 10 through the circulation pipe 15 branched from the second connection pipe 12. The bubble water flowing into the water storage tank (10) by the circulation pipe (15) is mixed with the bubble water of the water storage tank (10). The bubble generation efficiency can be increased by generating a larger amount of bubbles in the water storage tank 10 by the number of bubbles circulated to the water storage tank 10. A part of the bubble water passing through the throttling portion (50) is circulated through the circulation pipe, and the rest is put into the washing tank of the washing portion to wash the car material.

The washing unit for washing the car material using the bubble water is composed of a washing tank 100 connected to the second connecting pipe 12 to receive the bubble water generated by the bubble water generator and an agitating impeller And an electric motor (not shown) for rotating the stirring impeller.

The washing tub 100 is formed in a rectangular tube shape, and a support leg is formed at a lower portion thereof. The stirring impeller is installed in the lower part of the inside of the washing tank. The electric motor is installed in the washing tank to rotate the stirring impeller.

The applying means is for applying the herbal fermentation liquid to the tea material washed in the washing section. A cylindrical rotating drum into which a car material washed by a coating means is charged, and a spraying portion for spraying the herbal fermentation liquid into the inside of the rotating drum. The spraying unit may include a nozzle installed on an open upper portion of the rotary drum, a herbal fermentation liquid storage tank connected to the nozzle and a fermentation liquid supply pipe, and a pump installed in the fermentation liquid supply pipe to pump the herbal fermentation liquid.

The tea material to which the herbal fermentation liquid is applied through the application means is primarily dried through the drying section. An example of the drying unit is a conveying conveyor and an air blower for blowing wind to the car material moving along the conveying conveyor. The conveyor belt of the conveying conveyor is made of a mesh net structure so that the wind generated from the blower can be easily circulated up and down the conveyor belt. In addition to the above-mentioned examples, a conventional known drying apparatus can be used as the drying unit.

The primary material that has been dried in the drying section is treated by the smelting treatment section. While conventional processing can be used for smoothing, it is preferable to use an automated method for mass production. Conventional well-known automation machines can be used as a sound processing unit for mass production. For example, it is made up of a scraping container into which the dried car material is fed, and a rotating impeller installed in the scraper container and stirring the car material. The heating temperature, stirring time and the like are controlled by the controller.

The tea material that has been smoked in the above-mentioned smoothing unit is taken out of the soft container and placed on the seat, and is spread well and cooled. The cooling process can be carried out by leaving the tea material at room temperature in the unfolded state, or by airing using a blower or the like.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
