Field of the Invention [0001] The present invention relates to a device for drying a coffee grounds, and more particularly, to a device for drying a coffee grounds remover which is capable of preliminarily drying coffee grounds in a step of collecting and transporting coffee grounds by mounting the device on a vehicle.

Coffee consumption continues to increase worldwide as well as in Korea. Accordingly, not only the production amount of coffee is increased, but also the amount of coffee residue produced after the production of coffee is also increasing every year.

Such coffee grounds are remnants obtained by heating a coffee bean having a vegetable content to a predetermined temperature or higher and extracting the coffee stock solution from finely pulverized powder. The remaining coffee grounds are excellent in ventilation due to the nature of plant cell tissues including lignin and cellulose as the main components of the plant, It has a uniform distribution, contains 15 to 25% coffee oil, and its solids can be used as an energy source with a high calorific value of 6000 kcal or more per kg.

In recent years, attempts have been made to produce environmentally friendly solid fuel by recycling these coffee grounds as the main raw material of solid fuel, and drying of the coffee residue is essential. Korean Patent Registration No. 10-1582340 discloses a technology relating to a bio-crude oil production system using coffee beans.

However, when a hot-air type dryer such as the Korean Patent Laid-Open No. 10-2010-0120813 is used for drying the coffee grounds, a lot of drying energy is consumed.

The mobile coffee ground drier 10 according to the present embodiment is mounted on a vehicle 20 having a loading table 22 and a driver's seat 21 provided at the front end of the overhead loading table 22. [ For example, as the vehicle 20, a vehicle capable of loading cargo is sufficient.

The frame 100 is vertically fixed on the mount table 22 of the vehicle 20.

A drying cylinder 200 having an inner hollow cylindrical shape is rotatably installed on one side of the frame 100 (that is, in a direction toward the rear of the vehicle 20) so that coffee grounds can be received. That is, the drying cylinder 200 serves to dry the coffee grounds while rotating, and a separate rotation driving unit or a roller may be installed for rotation although not shown.

On the upper side of the frame 100, a charging port 300 for charging the coffee remnants into the drying cylinder 200 is formed. The frame 100 has an opening at a portion connected to the drying cylinder 200 so that the coffee grounds injected into the inlet 300 are supplied into the drying cylinder 200 through the opening.

The air suction part 400 is fixedly installed on the other side of the frame 100 (i.e., in the direction toward the front of the vehicle 20). The air intake part 400, the frame 100, and the drying cylinder 200 are arranged in this order on the mount table 22 of the vehicle 20. The air suction unit 400 sucks the outside air into the drying tub 200.

The air intake part 400 has a conical shape and a plurality of blades 401 is formed on an inner circumferential surface thereof. The plurality of vanes 401 are spaced apart from each other by a predetermined distance to form a curved shape so that external air is bent along the plurality of vanes 401 and introduced into the drying cylinder 200 .

That is, the air drawn into the air intake part 400 through the plurality of vanes 401 formed in the air intake part 400 is swirled and flows in a spiral manner. Thus, the introduced air flows relatively fast inside the drying cylinder 200, so that drying of the coffee residue can be performed more effectively.

The frame 100 includes a penetration portion for introducing air into the drying cylinder 200. The air sucked by the air suction portion 400 passes through the penetration portion and flows into the drying cylinder 200, And flows into the inner cylinder 220.

The drying drum 200 rotates to dry the coffee grounds while transferring the coffee grounds from the lower part to the upper part or from the upper part to the lower part. At this time, the first and second conveying members 211 and 221 serve to mix and convey the coffee grounds and the air, thereby evaporating moisture remaining in the coffee grounds.

In this case, it is preferable that the inclination formed by the first and second conveying members 211 and 221 is formed in a direction that does not disturb the flow of air.

As shown in FIG. 3, when the air passes through the second conveying members 221, the second conveying members 221 are projected to be inclined along the direction in which air flows (see arrow direction) , And the first conveying members 211 are also protruded to be inclined along the direction in which air flows (see arrow direction).

That is, the first conveying members 211 extend in the direction toward the inlet 300 and the air inlet 400, and the second conveying members 221 extend in the direction of the inlet 300 and the air And is formed to extend in a direction away from the suction portion (400).

When the coffee grounds and the air flow into the inner cylinder 220 through the penetration portion, the coffee grounds and the air are first introduced into the inlet 300 and the air inlet 220 along the second feeding members 221, And moves in a direction away from the portion 400. The coffee grounds and the air are then transferred to the outer cylinder 210 and transferred to the inlet 300 and the air inlet 400 along the first transfer members 211 of the outer cylinder 210 As shown in Fig. The air sucked into the air intake part 400 and the coffee grounds injected into the input port 300 are transferred to the outer cylinder 210 after passing through the inner cylinder 220.

In this case, the drying cylinder 200 is rotated repeatedly, so that the coffee grounds accommodated in the lower side of the outer cylinder 210 are moved upward, and the operation of dropping from the upper side of the outer cylinder 210 is repeated. The coffee grounds are dried by the air while repeating the above operation.

Thereafter, the relatively heavy air, which has been dried to a relatively heavy degree, is transferred to the discharge port (not shown) formed below the frame 100 and discharged. The relatively light air, which has removed the moisture of the coffee residue, And the air is discharged to the air discharge unit 500 formed at the upper end of the air discharge unit 500. At this time, the discharge port and the air discharge part 500 have a shape penetrating through the coffee grounds and the air so that they can be discharged to the outside.

FIG. 4 is a schematic view showing a state in which a filter unit and a storage container are provided in the mobile coffee residue drying apparatus of FIG. 1;
