Description

Hot-air circulation coffee bean roasting device {Hot-air Roasting device}

The present invention relates to the technical idea of a roasting device that improves the flavor of coffee beans by applying heat to green beans. More specifically, the simplification of the overall structure not only makes it extremely convenient to install and use, but also ensures that the heat flow is continuous within the space where the green beans are accommodated. In addition to being able to produce high-quality coffee beans by circulating uniformly, the coffee by-products mixed in the heat stream are automatically dusted due to the flow of gas that repeatedly rises and falls depending on the temperature difference, thereby actively improving convenience of use. It is about a coffee bean roasting device.

Typically, coffee beans are manufactured through a roasting process in which green beans are roasted at a temperature of 220 to 230 degrees Celsius for about 30 minutes, and coffee beans that have gone through this roasting process bring out various flavors.

The roasting method is divided into a direct fire method in which green beans are placed in a drum and heat is directly applied to roast the green beans, and a hot air method in which the green beans are roasted by circulating hot air between the beans. The direct fire method is economical and has the advantage of directly expressing the taste and aroma of coffee. The disadvantage is that the green coffee beans do not expand and uniform roasting is difficult. On the other hand, the hot air method has the advantage of making it easy to roast large quantities of green coffee beans as roasting is uniform and possible in a short time, but it has the disadvantage of making it more difficult to express individuality than the direct fire method.

Meanwhile, with the recent activation of cafe culture, the demand for coffee beans is rapidly increasing, and hot air roasting devices, which are excellent for mass production of coffee beans, are being steadily developed to respond to the demand. As one of the prior art examples related to this hot air type roasting device, Publication Patent Publication No. 10-2019-0030260, “Coffee Bean Roasting Device,” is published, and the technology is internally connected to the left and right, leading to the input and discharge of coffee beans, so that one side It is a roasting device composed of a rotating body of a cylindrical mesh body including a downward ramp, a rotating shaft coupled to one side of the rotating body, a motor that drives the rotating shaft, a near-infrared module disposed in parallel with the rotating shaft, and a heat source.

The above technology has the advantage of maintaining a uniform roasting temperature using a near-infrared module, but the coffee beans were not perfectly roasted because hot air could not be circulated flexibly between the beans.

Another example of the technology related to the hot air type roasting device is Publication No. 10-1953873, “Coffee bean roasting device,” which includes a main body for accommodating green coffee beans, a roaster for heating and roasting the coffee beans, and It is a roasting device that consists of a cooling unit that cools the roasted coffee beans, and the roaster is further equipped with a stirring member consisting of three screw blades.

In this technology, because the stirring member agitates the beans evenly, high-temperature hot air is supplied uniformly, and because the burner heats the roaster in close proximity, the outside and inside of the beans are evenly roasted, producing coffee with improved taste and aroma. However, the green beans are used only once. Since the roasting hot air rises and is lost to the outside, not only is the flavor contained in the hot air lost, but the energy consumption required for roasting is also serious.

Therefore, the present invention improved the overall structure of the roasting device to produce high-quality coffee beans by allowing hot air to enter between green beans in detail, and also developed a roasting device that can actively minimize power consumption by continuing the circulation of hot air. .

As shown in FIG. 1, the roasting device 100 of the present invention includes a hot air blower 10 that generates and supplies high-temperature heat in one direction, a receiving portion 20 that receives heat and roasts the received green beans, and a heat current in the heat stream during the roasting process. It consists of a dust collection unit 30 that separates and discharges the collected coffee by-products, and a cover body 40 that shields the upper part of the dust collection unit.

The heater 10 has a built-in heat source installed inside, is connected to the cable, and operates by receiving power. According to a preferred embodiment of the present invention, the heater 10 includes a hexahedral frame 10a, a heat source (not shown) built into the frame, and a fan disposed below the heat source to generate an upward airflow (Fan, drawing). (not shown), a fan switch (10b) installed on one side outside the frame and connected to the fan to determine operation, and a fan switch 10b installed on one side outside the frame and connected to a heat source to control operation, operation time, and temperature. It consists of a timer 10c.

Meanwhile, the hot air blower 10 further includes a nozzle 11 that guides the discharge path and creates an discharge shape to smoothly discharge the heat generated from the heat source.

As shown in FIG. 3, the nozzle 11 is exposed to the upper part of the frame 10a and is coupled to the bottom of the receiving portion 20, and has a nozzle body 11a having an upper and lower inner cylinder shape to discharge the high temperature heat formed inside the frame. ), and a shielding plate (11b) disposed at a position adjacent to the upper surface in the inner center of the nozzle body and forming a discharge path (S) to allow lateral diffusion and discharge of hot air, and the edges of the nozzle body and the shielding plate are vertically aligned. It is composed of a connecting stand (11c) that connects and divides the discharge passage (S) into multiple parts.

As mentioned, the heat flow passing through the nozzle 11 initially rises vertically along the nozzle body 11a, and the heat flow rising vertically meets the shielding plate 11b and spreads laterally for a while before discharging into the discharge path (S ) and rises again.

The heat flow that rises vertically is gently spread by the shielding plate (11b), and the heat flow that passes through the shielding plate is subtly split once more while passing through the discharge path (S) divided by the connecting rod (11c) to the receiving part. (20) is supplied.

In particular, the connecting rod (11c) connects the upper surface of the nozzle body (11a) and the edge of the shielding plate (11b) diagonally to rotate and discharge hot air, and further strengthens the rotating force of hot air by forming the connecting rod into a curved surface like a screw. .

In other words, the heat flow generated through the heat source is primarily diffused by the shielding plate (11b), and the primary diffused heat flow is discharged into the discharge path (S) divided along the curved surface of the screw-shaped connection bar (11c). As it does so, it circulates and moves to the receiving part (20). The heat flow continuously circulates through every corner of the receiving portion 20 through a circulatory action, thereby roasting the green coffee beans evenly.

The receiving portion 20 is combined with the nozzle 11 while accommodating the green coffee beans inside, and the green coffee beans are thermally processed by the supplied hot air to produce coffee beans.

The receiving portion 20 includes a body 21 that accommodates the green coffee beans, a first mesh net 22 installed on the bottom of the body to prevent the green coffee beans from falling, and a handle installed horizontally on the side of the body to guide the user's grip. It consists of (23).

The body 21 is formed in a vertically cylindrical form, and green coffee beans can be put in or roasted coffee beans can be collected through the upper opening, and the lower opening is combined with the nozzle 11 to receive heat flow.

As mentioned above, the body 21 has an outer shape of upper and lower narrowing, so as the airflow rises, it gradually spreads along the expanding space of the body, and the airflow that was spreading and rising hits the upper part of the body and turns in a spiral direction. It circulates the heat current and induces it to descend again.

The first mesh net 22 is installed in the lower opening of the body 21, and is made of a mesh body with a diameter corresponding one-to-one with the lower opening, and receives the heat provided by the hot air blower 10, and the green coffee beans contained in the body 21 It plays a role in preventing coffee beans from falling. In addition, the first mesh network 22 guides the subtly dispersed heat flow from the nozzle 11 to be finely distributed by passing through a dense network.

It would be natural for the first mesh network 22 to be installed at a depth that does not interfere with the nozzle 11 coupled to the lower opening of the body 21.

The dust collection unit 30 is installed in an inner cylinder at the top of the receiving unit 20, and separates and collects coffee by-products mixed in the heat flow with a receiving groove 30a formed along the inner diameter due to the flow of gas that repeatedly rises and falls depending on the temperature difference. do.

The dust collecting part 30 is made up of a cylindrical entry part 31 that is fitted on the upper side of the receiving part 20 and receives heat flow, and a cylindrical shape with an open top, and is seated at the top of the receiving part, and the entering part penetrates the center. It is integrated and consists of a mounting portion 32 in which a receiving groove 30a is formed in the space between the inner diameter and the entry portion.

For example, there is a principle that hot wind tends to rise and cold wind tends to fall. Accordingly, the heat flow supplied from the heater 10 moves to the dust collection unit 30 via the nozzle 11 and the receiving unit 20 while rotating and circulating. The temperature of the heat flow that reaches the dust collection unit 30 is lowered by the cold outside air supplied from the upper side of the dust collection unit, and the air flow whose temperature has been lowered falls again. The descending airflow rises again while being warmed by the hot air supplied from the nozzle 11, and this rise and fall of the airflow is repeated infinitely while driving the roasting device 100.

The heat flow repeatedly rises and falls at the top of the dust collector 30 and continuously passes through the entry part 31, the mounting part 32, and the receiving groove 30a. At this time, the heat flow passes through the receiving groove 30a. In this case, the gas escapes easily, but the coffee by-products, which are heavier than the gas, cannot escape the receiving groove and gradually accumulate. This separates the gas and coffee by-products from the heat stream.

After the operation of the roasting device 100 is completed or during operation, if coffee by-products accumulate in the receiving groove (30a) above an appropriate level, the user can easily remove the dust collection unit 30 from the receiving part 20 to remove the coffee by-products. there is.

The cover body 40 shields the upper part of the dust collection unit 30 to prevent coffee by-products from being lost to the outside and at the same time performs the function of discharging part of the heat flow to the outside. For this purpose, the cover body 40 is seated on the top of the dust collection unit 30 to shield the upper part of the dust collection unit, and is composed of a body 41 that is internally connected up and down to discharge rising airflow to the outside, and a second mesh that shields the opening at the top of the body. It consists of a network (42).

In addition, the cover body 40 has a plurality of compression clips 43 installed downwardly along the outer peripheral surface of the dust collection unit 30 to press the outer peripheral surface of the dust collection unit 30, thereby completely restraining the cover body seated on the top of the dust collection unit from the dust collection unit.

The roasting device 100 of the present invention, which is configured as described above, has the minimum components required for roasting, the connection relationship between the components, and the operation method for roasting are extremely simple, so it can be conveniently used by anyone regardless of age or gender.

In addition, the heat flow is supplied in circulation from the nozzle 11, and the heat flow is diffused and circulated in the receiving part of the upper and lower chambers, so that the green coffee beans are roasted evenly and precisely, and as the circulation actively continues, the energy consumption required to drive the roasting device is reduced. You can actively save.

In addition, coffee by-products collected in the heat stream are automatically dusted due to the gas flow of the rising and falling air currents according to the temperature difference, making it possible to manufacture coffee beans of better quality than before, and the collected coffee by-products can be simply collected in the dust collection unit 30. Since it can be processed by removal, it is possible to provide a roasting device with excellent usability.
