Generally, a coffee roaster rotates a cylindrical steel drum and fires a green bean inside the drum with a flame applied to the drum surface to make a bean.

The coffee bean has no taste or flavor in itself, but the cell tissue of the bean curd is destroyed through the roasting process and various components such as fat, sugar, acid components, caffeine and the like are activated and externally released. That is, during the roasting process, certain components are strengthened and some phases are less influenced, thereby changing the taste and aroma depending on the roasting method.

Roasting methods include flame retarding, hot air, and semi-hot air blowing. Recently, far infrared ray roasting has been introduced.

For reference, a technique in which far-infrared ray roasting is performed in a state in which the far-infrared ray radiator is in direct contact with the coffee beans by mixing and heating the coffee bean and the far-infrared ray radiator in the roasting space is disclosed in Korean Patent Publication No. 10-2013-0081480 &Quot; Method of roasting coffee beans ", published on July 17, 2013).

As shown in FIG. 4, the configuration of the far-infrared coffee roasting method according to an embodiment of the present invention includes a step S10 of starting the operation, a step S20 of preheating the roaster drum, (S30) of igniting the gas burner when the green beans are put in, a step (S40) of roasting the green beans at a low temperature of 100 DEG C or lower together with the far-infrared rays (S80) of drying the green beans; a step (S70) of first cracking the green beans; a step (S80) of determining whether the temperature of the green bean is 180 degrees Celsius or more using a temperature sensor; (S90) when the temperature of the bean is 180 degrees Celsius or more (Step S90); and displaying a step of discharging the bean to the user before the bean is secondly cracked when the temperature of the bean is 205 degrees Celsius or more S100), door openings A step S110 of judging whether or not the beans are discharged using the food sensor, a step S120 of forcibly cooling the beans when the beans are discharged, and a step S130 for ending the operation.

The operation of the coffee roasting apparatus and method using far-infrared rays according to an embodiment of the present invention with the above-described structure will be described below.

The controller 344 of the control panel 34 preheats the roaster drum 35 to 170 degrees Celsius until the gas control valves 24, 27 and 29 are opened to allow the fuel gas to be supplied to the gas burner 30 through the gas pipe 28 and then the ignition driver 346 is operated to drive the igniter 55 so that the gas burner 30 is ignited do. The thermal power generated from the gas burner 30 is transferred to the inner cover plate 60 after the roaster drum 56 is heated via the heat transfer plate 54 so that even if the gas burner 30 is extinguished, Infrared rays are radiated from the inner cover plate (54) and the inner cover plate (60).

Next, the controller 344 of the control panel 34 determines whether or not the green beans have been inserted by using the green bean insert sensor 341 (S30), and then, when the green beans are inserted, The gas burner 30 is ignited at a turning point (turning point) at which the heat quantity of the gas burner 30 becomes intermediate (S40).

When the gas burner 30 is ignited, the controller 344 of the control panel 34 generates infrared rays radiated from the heat transfer plate 54 and the inner cover plate 60 made of ceramic material together with low-temperature (S50).

In this case, the controller 344 of the control panel 34 operates the second motor driver 348 to drive the second motor 12 so that the rotational power of the second motor 12 is transmitted to the roster drum 56. [ .

The controller 344 of the control panel 34 operates the first motor drive unit 347 to drive the first motor 1 so that the rotational power of the first motor 12 rotates the exhaust fan 6 . When the exhaust fan 6 rotates as described above, the suction generated in the exhaust fan body 8 causes the smoke generated in the roaster drum 56 to be roasted to the low temperature by the loading chute 62, Enters the exhaust fan body 8 through the pipe 65, the collector box 59, the connecting pipe 10 and the cyclone assembly 17 and then is discharged to the outside through the exhaust port 7. In addition, in the process of roasting the green beans at a low temperature, the fresh bean husks generated inside the roaster drum 56 are transported together with the smoke, the loading chute 62, the exhaust pipe 65, the collector box 59, The centrifugal force is reduced and then falls down to the cyclone barrel 21 provided at the lower portion of the cyclone assembly 17. [

When the green beans are continuously roasted at a low temperature, the endothermic reaction that the green bean absorbs heat is performed, and a drying step is performed in which the temperature of the roaster drum 56 is gradually increased as moisture is lost by 70 to 90% (S60 ). In this drying step, the color is changed to yellow color through yellowish green which is produced, and the fragrance which seems to bake fine bread is produced.

After the drying step, the carbohydrate of green beans is oxidized, and the primary cut is divided into a center cut (S70). In this primary cracking stage, the surface of the bean swells and becomes smooth, bringing the color closer to brown, and the divergence of hundreds of aromas and creams is at its peak.

The controller 344 of the control panel 34 uses the temperature sensor 342 to determine whether the temperature of the green bean is 180 degrees Celsius or more (S80). When the temperature of the green bean is 180 degrees Celsius or more, 30 are turned off and heated by only the far-infrared ray radiated from the ceramic heat transfer plate 54 and the inner cover plate 60 (S90).

When the temperature of the green bean becomes 180 degrees Celsius or more, an exothermic reaction for releasing heat occurs, and the internal temperature rapidly rises and the perfume ingredient of the coffee starts to be produced in earnest. At this time, The far infrared ray radiated from the cover plate 60 is used for mobilizing, thereby changing the divergence of the strong eruption into the beverage having soft sweetness to match the balance.

Next, the controller 344 of the control panel 34 uses the temperature sensor 342 to determine whether the temperature of the bean is above 205 degrees Celsius, (S100).

When the temperature of the bean is above 205 degrees Celsius, the aromas disappear rapidly. Therefore, when the beans are rapidly cooled at this point, the aroma loss can be minimized and secondary cracks of the bean can be prevented.

The controller 344 of the control panel 34 determines whether or not the beans are discharged using the door open sensor 343 (S110), and then the user opens the drum door assembly 50, The first motor 1 is driven by operating the first motor driving unit 347 so that the heat of the bean is transferred to the collector box 59 via the cooling tub shield 33, And then discharged through the exhaust port 7 to the outside of the exhaust fan body 8 through the connection pipe 10 and the cyclone assembly 17 so as to rapidly cool the beans at step S120.

The controller 344 of the control panel 34 operates the third motor driver 349 to drive the third motor 39 so that the rotational power of the third motor 39 rotates the scraper 37 . The scraper 37 stirs the beans in the cooling cylinder 36 evenly so that the beans are cooled when the temperature of the beans is kept uniform.

As described above, when the heat transfer plate 54 and the inner cover plate 60 are provided on the lower and upper portions of the roaster drum 56 and an exothermic reaction occurs to release heat from the bean sprouts, It is possible to improve the taste and flavor of the beans by making a rapid quenching before the secondary cracks of the beans are generated, while being steamed by only the far-infrared ray radiated from the inner cover plate 60 and the inner cover plate 60.
