Generally, coffee is divided into coffee beans, bean ground coffee and instant coffee. In the past, it has been enjoyed drinking instant coffee which is easy to handle and low in price. However, in recent years, as the living standard has increased and the population enjoying the taste and aroma of coffee has increased, there have been more and more shops selling coffee by roasting or roasting coffee beans, This is a trend that is increasing in preference.

Coffee beans do not taste and smell in themselves, but when roasted by heating the beans at high temperature, the cell tissue of the bean is destroyed and the fat, sugar, organic acid, and caffeine are activated and released to the outside, There is a difference.

Such roasting of coffee has been proposed in various ways depending on the type of coffee bean, the taste difference between individual coffee taste and aroma, and the structure of the roasting device.

Conventional coffee roasting is a method of roasting using a drum, a direct-burning method in which roasted beans are directly contacted with fire, a double drum is used to heat the outer drum, and hot air, which is transferred to the inner drum, A hot air blowing method is proposed.

For example, Korean Patent Laid-Open Publication No. 10-2014-0016102 discloses a coffee bean roasting apparatus capable of roasting a bean curd by a direct firing method, as disclosed in Korean Patent Publication No. 10-2009-0055112, A coffee roaster of a flame type is disclosed.

However, in the prior art of the flame burning method, the temperature of the cylindrical drum is rapidly heated by the flame and the coffee beans are frequently damaged. When the size of the flame is reduced, it takes a long time to raise the temperature to a proper temperature. There is a problem that the taste and aroma of coffee are deteriorated due to contact with outside air for a long time during drying and cooling.

On the other hand, as shown in Fig. 3, Korean Patent Laid-Open No. 10-2012-0139960 discloses a hot-air type coffee roaster.

However, the above technique has a disadvantage that the dust is scattered by hot air and the structure of the apparatus becomes complicated.

Accordingly, Korean Patent Laid-Open Publication No. 10-2015-0142772 discloses a device for separating and collecting silver skins peeled off from a heated bean while stirring the beans smoothly and roasting evenly in the course of roasting coffee beans as shown in FIG. A simplified roasting machine of coffee beans is disclosed.

However, the conventional techniques have the following problems.

That is, the prior art shown in Fig. 1 has a problem that it is not roasted evenly because there is no configuration for stirring the coffee bean.

The technique of FIGS. 2 to 4 has the wings for agitation, but functions to change the beans accumulated in the upper and lower layers to different positions, and it is difficult to roast all the beans evenly .

In addition, since the dropped beans are gathered only at the lower side due to the load, the heat supplied from the outside is not uniformly distributed to the respective beans but concentrated at the lower side.

In addition, the above-described conventional techniques have a problem in that maintenance and maintenance such as cleaning are inconvenient since it is difficult to separate the drum from the apparatus.

The drum assembly 100 is configured to receive heat from the outside to roast the grain C. The drum assembly 100 is provided with a rotating force of a motor on the front and rear sides of the drum assembly 100, So that it can be roasted evenly.

The drum assembly 100 includes a case 120 having an outer shape and a predetermined phase maintained therein, a drum 140 rotating in a state of receiving the grain C from the inside of the case 120, And a plurality of stirring blades 160 protruding inwardly from an inner circumferential surface of the drum 140 to forcibly stir the grain C when the drum 140 rotates.

The case 120 has a substantially cylindrical shape, and the inside of the case 120 is configured to open in a forward / backward direction. Therefore, the drum 140 can be rotatably received in the case 120.

In order to maintain the non-rotating state of the case 120, the lower part of the case 120 is seated on the object to be restrained, and thus the movement thereof may be restricted.

A handle 122 is provided on the upper side of the case 120. The handle 122 is configured to grasp the roasted cereal C when the roasted cereal C is to be taken or moved.

Various materials can be applied to the case 120 so long as the heat applied from the outside can be transmitted to the inside and the shape is not deformed.

That is, in the embodiment of the present invention, the circumferential surface is formed of a transparent material, for example, a transparent part 124 made of heat-resistant glass, and a ring-shaped metal flange 126 is positioned at the front / The pair of flanges 126 can be maintained in a state as shown in Fig. 10 without separation due to a tensile force applied by the plurality of tension members 128. Fig.

The drum 140 has a grain accommodating space 141 therein and is configured to have an outer diameter smaller than the inner diameter of the case 120 so as to be rotatable within the case 120.

The drum 140 is shaped into a cylindrical shape by the drum body 142 and the grain accommodating space 141 formed therein has a front cover 143 and a rear cover 143. [ 144, respectively.

A rear cover 144 is coupled to the rear end of the drum body 142 so as to shield the rear of the grain receiving space 141. The rear cover 144 is integrally coupled to the drum body 142, So that they are not separated.

The front cover of the drum body 142 is selectively rotatable to open the grain accommodating space 141 so that the grain C can be inserted or withdrawn.

To this end, a cover coupling hole 145 is formed at the tip of the drum body 142 so that the front cover 143 and the drum body 142 are coupled to each other and selectively opened.

The rim of the cover body 145 is formed in a ring shape with a center hole. The rim of the cover body 145 is firmly engaged with the front end of the drum body 142 and the outer diameter of the cover body 145 is larger than the outer diameter of the drum body 142, So as not to penetrate into the case 120. [

The perforated central portion of the cover engaging hole 145 communicates with the grain accommodating space 141 and the upper center may be engaged with the front cover 143 using a fastening member such as a screw.

Therefore, the front cover 143 positioned in front of the cover coupling hole 145 can rotate about the fastening member to open the grain accommodating space 141.

A stopper 146 protrudes from the front surface of the cover coupling hole 145. The stopper 146 is bent to protrude forward by slitting a part of the cover coupling hole 145. The stopper 146 interferes with the outer circumferential surface of the front cover 143 and restricts the rotation in the counterclockwise direction.

A shaft receiving portion 143 'is provided at a central portion of the front cover 143 so that a rotary shaft 261 serving as a rotation center of the drum 140 can be received. When the rotary shaft 261 is received in the shaft receiving portion 143 'with respect to the front cover 143 coupled to the cover coupling 145 so as not to move, the drum body 142 rotates about the rotary shaft 261 .

A support stand 149 is provided at the rear of the rear cover 144. The support 149 supports the rear half load of the drum 140 and guides the rotation of the drum 140.

For this, a rotation guide hole 147 is formed in the center of the support 149. The rotation guide hole 147 is formed so that a support shaft positioned on the same straight line as the rotation shaft 261 can be fitted into the rotation guide hole 147. The support shaft may be integrally formed with the rotation shaft 261, And may be configured to support the rear half load of the drum 140.

When the support shaft is integrally formed with the rotation shaft 261, it is preferable that a hole is formed at the center of the rear cover 144. When the support shaft and the rotation shaft 261 are formed separately, It is preferable that the rotation guide hole 147 is formed in a shortened state so as not to come into contact with the rear cover 144 while maintaining the inserted state.

The internal structure of the drum body 142 will now be described with reference to FIGS. 11 and 12. FIG.

11 is an exploded perspective view showing the external shape of a stirring blade 160 that is a substantial component of the drum assembly for raising cereals according to the present invention 100. Figure 12 shows a drum assembly 100 for roasting a cereal according to the present invention, Sectional view taken along the line A-A 'of Fig.

First, as shown in FIG. 11, three stirring blades 160 are arranged radially inside the drum body 142 as in the embodiment. The stirring vane 160 is configured to raise and lower the grain C when the drum 140 rotates. The stirring vane 160 is formed in a plate shape and is formed so as to be inclined so that one end thereof abuts.

In other words, the plate members having different angles are in contact with each other, and the other end thereof is fixed in contact with the inner circumferential surface of the drum 140, thereby dividing the grain accommodating space 141 described above into a plurality of sections.

More specifically, the stirring vane 160 includes a lifting portion 162 having a length corresponding to the length of the drum 140 and transferring the grains C upward, And a selection receiving portion 164 in which a receiving hole 165 is drilled to receive a part of the cereal C falling down after being conveyed upward by the stirring blade 160 inside the stirring vane 160.

In the embodiment of the present invention, the lifting portion 162 and the selection accommodating portion 164 are formed by bending one side of one sheet material. At this time, the selective accommodating portion 164 is bent to have a wider width than the lifting portion 162 A pair of rectangular receiving holes 165 are formed in the selective receiving portion 164.

The stirring blade 160 may be fixed to the drum body 142 in various manners. However, in the embodiment of the present invention, the drum body 142 is formed with a plurality of slotted slots 148, The insertion part 147 is protruded from the end of the part 164 and the lifting part 162 so that the insertion part is inserted into the slot 148 and then bent.

Accordingly, the stirring vane 160 and the drum body 142 are designed to minimize the harmful elements to the human body by not joining the coupling member or the welding or the like, and to improve the ease of assembly at the time of manufacture.

12, the imaginary extended surface of the lifting portion 162 and the selection accommodating portion 164 is located at the center of rotation of the drum 140, So as not to pass through.

The lifting unit 162 is moved in the counterclockwise direction as the drum 140 rotates in the counterclockwise direction and the drum 140 rotates counterclockwise as shown in FIG. The grains C placed on the upper surface of the lifting part 162 can not be raised to a high position but fall immediately.

Therefore, when a large amount of cereals C is accommodated in the grain accommodating space 141, it is difficult to agitate the grain. In order to solve this problem, the lifting portion 162 is disposed on the inner peripheral surface of the drum body 142 It is preferable to be formed so as to be inclined so as to have a certain angle without being perpendicular to the tangent to the tangent line and to have an upward slope toward the inner side within a range not exceeding the center of rotation.

The height of the stirring vanes 160 is smaller than the radius of the drum 140. When a plurality of stirring vanes 160 are installed in the drum body 142 in the radial direction, the inner end of the stirring vane 160, when viewed in a direction perpendicular to the inner circumferential surface tangent of the drum body 142, .

A part of the grain C falling on the upper surface of the lifting part 162 does not directly hit another stirring blade 160 but drops into a space between the stirring blade 160 and the stirring blade 160, When the drum 140 further rotates, the grain C dropped by the lifting part 162 penetrates through the selective receiving part 164 to disperse the grain C evenly.

Meanwhile, the lifting portion 162 is disposed in parallel with the selection receiving portion 164 of the other stirring vanes 160 disposed adjacent to each other.

12, the selection receiving portion 164 of the stirring blade 160 located at the lower left side and the lifting portion 162 of the stirring blade 160 located at the right side are parallel to each other, and the stirring blade 160, The lifting portion 162 of the stirring vane 160 is parallel to the selection receiving portion 164 of the stirring vane 160 positioned adjacent to the right side.

This is because the multiple stirrer 160 has the same shape and is characterized by the above-described shape, so that a large impact is not applied to the falling cereal C after being lifted up by the lifting portion 162 .

Hereinafter, the operation of the stirring vane 160 will be described with reference to FIGS.

FIG. 13 is a longitudinal sectional view showing the state of the grain when the drum 140 rotates in the drum assembly for raising cereals 100 according to the present invention, and FIG. 14 is a longitudinal sectional view showing the state of the drum assembly 100 for roasting cereals according to the present invention, FIG. 15 is a longitudinal sectional view showing the dropping state of the grain C when rotated counterclockwise at a constant angle.

13 to 15, the receiving hole 165 is indicated by a square in consideration of the fact that the material thickness of the stirring vane 160 is not distinguished due to the thinness of the material.

First, as shown in FIG. 13, when the grain C is put into the drum body 142, the grain C is gathered on the lower side by the load.

When the drum 140 is rotated in the counterclockwise direction, the grain C is lifted by the upper surface of the lifting part 162 as shown in FIG. 14, and a certain amount of the grain C falls downward.

At this time, the dropped cereal C is not brought into contact with the selection receiving portion 164 located at the lower left but falls down, and is gathered between the stirring blades 160.

When the drum 140 further rotates counterclockwise by a predetermined angle to reach the state shown in FIG. 15, the grain C remaining on the upper surface of the lifting part 162 moves to the left to fall, The dropping cereal C is accommodated in the stirring vane 160 through the receiving hole 165 as the selective receiving portion 164 is positioned below the swinging vane 162.

Therefore, the grain C dropped downward by the rotation of one stirring blade 160 also falls into the space between the stirring blades 160 and is accommodated in the stirring blade 160 according to the angle, The grain C can be dispersed and accommodated.

As a result, the heat provided from the lower side is provided to the inside through the outer surface of the lower portion of the drum body 142, and is uniformly transferred to the grain C, so that the roasting process can smoothly proceed.

In addition, the grains C dropped in FIG. 15 are inclinedly contacted with the selection receiving portion 164 located at the lower left, so that a large impact can not be transmitted and breakage can be prevented.

Meanwhile, the drum assembly 100 can change the receiving position of the dropped cereal C according to the rotating direction of the drum 140.

Other operations of the drum assembly 100 will be described below with reference to FIGS. 16 to 18 attached hereto.

As shown in FIG. 16, the grains C contained in the grain accommodating space 141 are gathered on the lower side by the load. When the drum 140 is rotated clockwise by a certain angle, the grain C And is received in the stirring vane 140 through the receiving hole 165 of the stirring vane 140 located on the right side as shown in Fig.

When the drum 140 is further rotated clockwise by a predetermined angle, the grains C located inside the stirring vane 160 drop through the receiving hole 165 as shown in FIG.

At this time, the dropped grains C are received inside through the receiving holes 165 of the lower stirring vanes 160.

As a result of repeating this process, the grain C is roasted repeatedly in the stirring vane 160 without moving into the space between the stirring vanes 160, but moving into the other stirring vane 160.

The scope of the present invention is not limited to the above-described embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the scope of the present invention.
