S10; Primary sterilization step

As described in the prior art, the germinated coffee is activated by the enzymes in the coffee bean (C), which was in a dormant state, so that the existing various proteins, minerals, fiber and GABA (Gamma Amino Butyric Acid) (C) were found to be distributed uniformly in germinated coffee beans. In addition, the caffeine and tannin components are reduced, and the coffee beverage using the germinated coffee beans is characterized by softening the taste and flavor.

However, germination occurs in the course of germination of the coffee bean (C), and the germination loses the original taste of the coffee.

Therefore, the coffee beans C placed on the net 110 are sterilized by using the ozone water flowing in the first water tank 200 for the purpose of eliminating viable bacteria causing germination. At this time, the ozone concentration of the ozonated water is preferably 0.20 ppm to 0.30 ppm, and the oven water immersion of the coffee beans (C) for sterilization is preferably 30 seconds to 60 seconds.

To this end, the coffee beans C are placed on the net 112 of the net 110. Each hole of the net 112 is preferably circular or elliptical for smooth movement of the coffee beans C so that ozonated water, washing air, tap water, mixed water and purified water flow smoothly up and down the net 110 It is possible to form a square as shown in Fig.

The net 110 of the present embodiment includes a first net 111, a first frame 111 which surrounds the first net 112 and is spaced apart from the upper and lower layers, An inclined stage 113 disposed obliquely and opposed to the upper and lower layers of the front end so as to form a nozzle to induce the inflow of running water through the front end of the first frame 111, (Not shown).

The ozonated water flows at a constant rate and is a flowing water that applies water pressure to the surface of the coffee bean (C).

Although the net 110 may be directly inserted into the first water tank 210 of the first water tank 200, the net 110 may be inserted into the first water tank 210 by inserting the net 110 into the hanger 120, .

The hanger 120 of the present embodiment includes a second net 122 and a second frame 121 of a multilayer structure that supports the periphery of the second net 122 and is spaced apart from the upper and lower layers, A cover 123 that covers and fixes the upper surface of the vibrator 130 so as to cover the upper surface of the vibrator 130 and a cover 123 that supports the vibration of the vibrator 130 to be uniformly distributed over the cover 123, A support shaft 125 vertically installed on the reinforcing projection 124 and a cover 123 for exhausting the air conveyed through the high pressure hose 126a to the inside of the second frame 121 And a through hole 121a through which the connecting protrusion 114 is inserted and removed is formed inside the entrance of the second frame 121 through which the net 110 is drawn in and out.

Further, the connection protrusion 114 is made of a magnetism-resistant material, and a magnet 127 is installed to magnetically fix the connection protrusion 114 in a section of the second frame 121 on which the connection protrusion 114 is seated.

The inclined band 113 of the net 110 is connected to the entrance of the second frame 121 by the entrance of the entrance of the second frame 121 by the entrance of the entrance 110 of the coffee bean cassette C, So that the coffee beans C placed on the first net 112 come into direct contact with the running water.

The hanger 120 on which the net 110 is placed is pulled to the first water tank 200, the second water tank 300 and the third water tank 400 through the support shaft 125, Since the net 110 itself can be immersed in the mesh, the automation work becomes possible.

The first water tank 200 of the present embodiment includes a first water tank 210 in which oily water is stored temporarily and a plurality of water inlets 211 are formed on the front surface and a plurality of water outlets 212 are formed on the rear surface, ; A collecting container 220 connected to the rear surface of the first water tub 210 to collect and discharge the ozonated water discharged from the drain port 212; A heat exchanger (230) for cooling the warmth of the ozonated water discharged from the collection container (220); A circulation pump 240 for pumping ozone water cooled in the heat exchanger 230; And a branching mechanism 250 for receiving the ozonated water flowing in the pumping of the circulation pump 240 and dividing the ozonated water into an inlet pipe 251 which communicates with the plurality of inlet ports 211, respectively.

Further, the inlet 211 forms a relatively large intake range toward the lower layer and the drain 212 forms a relatively small drainage range toward the lower layer.

When the ozone water flows into the first water tank 210, a large amount of ozone water flows into the lower water layer than the upper water layer, so that the stagnation of the ozonated water due to the water pressure in the lower layer is minimized, A stream is formed in the upper layer with a larger range. As a result, the difference in flow rate of ozone water according to the position in the first water tub 210 can be minimized, and the coffee beans C can be sterilized and cleaned with ozone water at a constant flow rate regardless of the depth of ozone water.

The ozonated water in the first water tub 210 sterilizes live bacteria on the surface of the coffee beans C through self-sterilizing power and sweeps off various fine substances accumulated on the surface of the coffee beans C.

If the immersion of the coffee beans C in the ozonated water is less than 30 seconds, sufficient sterilization of the coffee beans C can not be expected. If the ozonated water is immersed for 60 seconds or longer, It can damage itself and inhibit germination.

On the other hand, the temperature of the ozonated water is preferably 2 ° C to 5 ° C in order to inhibit the activity of live bacteria remaining on the surface of the coffee bean C and to remove various foreign substances and toxic substances. Since the ozone concentration is lowered by heating the ozone water, the sterilizing and toxic removal function for the coffee beans (C) may be substantially faded. Also, the temperature lower than the above range may weaken the physiology of the coffee beans (C) and inhibit germination of the coffee beans (C).

The germicidal device of the present embodiment is provided on the support shaft 125 so as to contact with the reinforcing protrusions 124 and constitutes a vibrator 130 for driving the network 110 to vibrate through the hanger 120.

As a result, in the primary sterilization process, the vibrator 130 vibrates and shakes the coffee beans C, thereby enhancing the sterilization and cleaning effect.

The lifting device 140 is constituted by a piston 142 connected to the support shaft 125 and a hydraulic cylinder 141 for moving the piston 142 up and down.

Therefore, the hanger 120 can be moved and lifted and lowered to the designated position via the support shaft 125, so that the net 110 can be transferred and immersed in the first to fourth water tanks 200, 300, and 400.

Since the net 110, the hanger 120, the vibrator 130 and the elevating device 140 operate as a set, the net 110, the hanger 120, the vibrator 130, and the elevator 140 ) Are collectively referred to as a coffee bean feeder (100).

S20; The first washing step

When the primary sterilization by the ozone water is completed, the kip pan (C) is cleaned by high-pressure air injection to remove foreign matter. The pressure during high-pressure cleaning is suitably from 100 to 120 bar (10,000 to 12,000 kPa). If you wash at less than 100 bar, the washing will not be done well. If you wash at a pressure higher than 120 bar, the coffee bean may be damaged.

At this time, the high-pressure air injection is performed through the exhaust pipe 126 provided in the cover 123, and the high-pressure air is transferred to the exhaust pipe 126 through the high-pressure hose 126a. It is preferable that a plurality of exhaust pipes 126 are dispersedly disposed on the cover 123 so that the entire coffee beans C dispersed in the first net 112 can be uniformly cleaned.

5 is a perspective view explaining a second water tank of the germicidal device according to the present invention.

S30; Second sterilization step

Secondly, sterilization is carried out by immersing the net 110 in which the coffee beans C are placed in the second water tank 300 in which ordinary tap water is stored for about 1 hour, and more specifically, immersed in 55 to 65 minutes do. At this time, it is preferable that the tap water is stored in the second water tank 300, the tap water temperature is 10 ° C to 15 ° C, and the second water tank 300 is kept at the first temperature Thereby constituting a regulating device 330. Fig.

The second water tank 300 according to the present embodiment includes a second water tank 311 for storing tap water and a second water tank 311 provided so as to be spaced apart from the bottom surface of the second water tank 311 and having a plurality of air outlets 312a. A first cylinder 310 configured as a partition 312; A carbon dioxide supplier 320 for injecting carbon dioxide between the bottom of the second tank 311 and the first partition 312; And a first temperature regulating device 330 for measuring the tap water temperature in the second water tub 311 and heating or cooling the water to maintain the predetermined temperature.

As is well known, tap water contains chlorine ions and sulfate ions of about 10 mg / L having a sterilizing function, so that the coffee beans (C) are secondarily sterilized with a relatively weak sterilizing power as compared with ozone water.

When the temperature applied to the coffee bean C is relatively higher than that during the primary sterilization, the temperature environment of the coffee bean C increases, thereby promoting the germination of the coffee bean C.

During the second sterilization after completion of the primary sterilization, carbon dioxide is continuously supplied into the tap water. Carbon dioxide temporarily inhibits germination during the sterilization process, and kills various live bacteria located in the coffee bean (C).

The ozonated water utilizing the primary sterilization and the tap water used for the secondary sterilization can be reused several times, so that the state of the ozonated water and the tap water are checked to judge whether or not to replace the ozonated water.

S40; Second washing step

When the secondary sterilization is completed, the coffee beans C are cleaned according to the above-described cleaning method.

The cleaning method is performed by injecting air at a high pressure through the exhaust pipe 126. Since this has been described above, the description thereof will be omitted here.

FIG. 6 is a perspective view explaining the third water tank of the germicidal device according to the present invention, and FIG. 7 is a side cross-sectional view showing a state in which the coffee bean is dipped into the mixed water in the germicidal device according to the present invention.

S50; Germination stage

When the second washing is completed, the net 110 on which the coffee beans C are placed is immersed in the mixed water (W) mixed with the onion juice and the purified water. At this time, since the mixed water W is stored in the third water tank 400 from which air bubbles are exhausted from the bottom surface, air for germination of the coffee beans C can be continuously supplied.

The third water tank 400 according to the present embodiment includes a third water tank 411 for storing the mixed water W and a plurality of air outlets (not shown) provided so as to be apart from the bottom surface of the third water tank 411 And a second partition (412) having a first partition (412a) formed therein; An air feeder 420 for injecting air into the space between the bottom surface of the third tub 411 and the first partition 412; And a second temperature regulating device 430 for measuring the temperature of the mixed water W in the third tank 411 and heating or cooling the mixed water W so as to be maintained at the specified temperature.

Since the germination temperature of the coffee beans C using the mixed water W should be a relatively higher temperature than the secondary sterilization temperature, it is preferable to set a temperature difference of at least 10 캜 so that the coffee beans C effectively detect the temperature difference Do. Further, it is preferable that the temperature is not higher than 30 deg. C which is the general forming temperature of the coffee bean (C).

When the immersion for germination is carried out, the immersion depth of the netting is such that 1/4 to 1/5 of the coffee bean C is exposed above the water surface of the mixed water (W), and the vibrator (130) And vibrations are applied to the net 110 soaked in the coffee beans C for 10 to 30 minutes. Whereby the coffee bean C is rotated over the net 110 so that the exposure of the coffee bean C over the water surface is repeated. Since the bioactivity of the coffee beans C is increased through this process, the initial germination rate of the coffee beans C can be increased.

For reference, the onion juice contains 26 mg / 100 g of calcium, 805 mg / 100 g of potassium, 1890 mg / 100 g of dietary fiber, and 38 mg / 100 g of polar group. In particular, onion juice contains quercetin, which has a blood pressure reduction function, in order to strengthen the immunity that weakens as the age increases, thus helping to suppress the blood pressure increase by coffee caffeine. Therefore, the blood circulation is not smooth and the immunity against cardiovascular disease is degenerated and the burden is not burdened, it helps to make nutritious and functional coffee beans to restore health. In addition, since the onion juice contains protein, carbohydrate and other nutrients such as vitamin C and calcium, phosphorus and iron, it absorbs various nutrients contained in the mixed water (C) during germination of the coffee bean (C) Absorbed.

For example, onion juice mixed into purified water is poured into 10 kg of onion 3 L of purified water and heated for 10 to 11 hours to extract onion juice. In this process, the water is re-supplied several times so that the temperature of the water does not exceed 90 ° C. In this process, the supply of purified water is continuously reduced.

The onion juice thus collected was mixed with 50% to 60% of purified water to prepare a mixed water containing 17 mg / 100 g of calcium, 432 mg / 100 g of potassium, 1011 mg / 100 g of dietary fiber, and 17 mg / 100 g of polylactic acid W). The mixed water (W) contains a large amount of various minerals, dietary fiber and quercetin, and the sugar content is also high.

The mixed water W thus formed is mixed with at least one of gibberellin, cylocinon, ethylene, hydrogen peroxide, auxin, potassium nitrate and thiourea to promote germination, preferably gibberellin and potassium hydroxide which are effective for promoting germination of coffee bean 200ppm to 500ppm of the mixed solution is injected into 1L of the mixed water (W).

When the specified driving time of the vibrator 130 has elapsed, the driving of the vibrator 130 is terminated and the second temperature regulator 430 gradually increases the temperature for 3 hours to 4 hours through heating, Lt; 0 > C.

The thus-finished germinated coffee bean can be roasted by an ordinary method to produce an instant coffee or a coffee bean, and if necessary, it can be used as an additive for rice cakes and confections.

As a result, the germination time of the coffee beans C is shortened without sprouting in relatively 5 to 6 hours through a relatively small amount of mixed water (W), reusable ozonated water and tap water. In addition, since the coffee bean (C), which has been immersed in tap water at low temperature after sterilization by ozonated water, absorbs various minerals of gonorrhoeae rapidly for germination at a relatively high temperature, the coffee beans containing a large amount of minerals C).

As a result of analyzing the constituents, 3 g of the ground coffee powder germinated by the above-described method was mixed with 150 ml of the regular purified water at 80 ° C, and 10 samples were analyzed. As a result, the calcium and potassium were 15% , An increase in dietary fiber by an average of 23%, and an increase of 82% in polabonoids and an average increase of 191% in quercetin.

Of course, it was confirmed that the composition of the coffee bean powder was different according to the management method of the germinated coffee bean, but it was confirmed that the overall beneficial ingredient of the coffee bean increased compared to the coffee bean germinated by the conventional method as a whole.
