The present invention relates to fuel pellets and briquettes including a coffee parchment, and will be described with reference to FIGS.

4 and 5 is a table showing the components of the parchment used in the fuel pellet including the coffee parchment according to an embodiment of the present invention, Figure 4 is a parchment three years have passed since the production, Figure 5 Is a coffee parchment that has not been produced for more than one year, and the coffee parchment contains 7.9-8.2 g of water, 0.1-0.2 g of fat, 1.4-1.7 g of protein, 0.3-0.7 g of ash, and 89.5-90 g of carbohydrate per 100 g. Include.

As such, the coffee parchment has a low lipid content, and thus the adhesiveness of the parchment and the fluidity during the production of the pellets have a problem in that the utilization of the fuel is lowered.

Accordingly, the present invention is to solve the above problem of productivity degradation to utilize the parchment as fuel.

Hereinafter, a fuel pellet manufacturing method including a coffee parchment according to an embodiment of the present invention will be described with reference to FIGS. 6 to 8.

[실시예 1]Example 1

First, as shown in Figure 6, to remove the outer shell of the coffee cherry (S110). Then, the coffee from which the outer shell is removed is first dried (S120). The reason for performing the drying process is to effectively remove the mucus surrounding the green beans while separating the parchment later.

On the other hand, before the drying process may be performed by washing with water to remove the mucus after the drying process.

Then, the outer shell is removed and the parchment on the outside of the dried coffee beans are separated by a machine or by hand (S130).

Then, the parchment obtained in the above separation process is collected and ground to a predetermined size (S140). The predetermined size may be 5 mm or less. This size is intended to increase the calorific value while allowing the transfer and compaction in the fuel pellet manufacturing process in the future.

Then, the ground coffee parchment is dried again (secondary drying) (S150). This process of re-drying the parchment is intended to control the moisture content in the parchment which is required for the subsequent compression process.

Preferably the amount of moisture contained in the parchment is 10% to 30% or less of the total weight of the parchment. This is to ensure that there is no change in physical properties when hot pressing at a later time and to obtain a high quality fuel pellet.

Then, the parchment is compressed (S160). This pressing process may be performed by preparing a predetermined mold mold according to the size of the pellet to be manufactured and pushing the parchment at high pressure toward the mold mold.

Finally, after the pressing process, a fuel pellet having a predetermined size is obtained (S170).

[실시예 2]Example 2

As shown in FIG. 7, the step of removing the outer shell of the coffee cherry (S110), the first drying step (S120), and the parchment separation step (S130) are performed in the same manner as in Example 1.

Thereafter, without passing through the crushing step (S140) and the second drying step (S150) of Example 1, after the parchment separation step (S130) after the parchment in the process of conveying the parchment for pressing before the compression for producing fuel pellets In order to increase the fluidity of the treatment (S145).

The reason for performing the fluidity increasing step as described above is to prevent this, as shown in Figures 3 and 4, the parchment is very low in the mold component is not easily pushed out in the mold frame during the molding process.

This fluidity increasing step (S145) adds 0.5-5 percent (%) (preferably 1-2%) of the fluidity increasing substance to the total weight, which includes water, starch, lignin or Of course, any one selected from ocher or a mixture of two or more thereof may be used, and other materials may be included.

Then, after the parchment separation step (S130), and before pressing to produce fuel pellets, a cohesive increase step for increasing cohesion between parchments is performed (S155).

The coffee parchment contains 3.21% of lignin, which plays an important role as an adhesive in the molding process, and is very low compared to 7.42% of apple trees, which greatly reduces the cohesion of the material. Add 0.5% to 5% (preferably 1-2%) of the adhesive component (gelatin, etc.) to the parchment, but the sum of the fluidity increasing substance and the adhesive component is 1-5% of the total weight (preferably 2% or less).

Then, the parchment is compressed (S160). This pressing process may be performed by preparing a mold mold and pushing the parchment at high pressure toward the mold mold.

[실시예 3]Example 3

As shown in FIG. 8, the outer shell of the coffee cherry is removed (S110), and the coffee having the outer shell removed is first dried (S120), and the parchment is separated (S130).

Then, the parchment obtained in the process of separating the parchment is collected and pulverized to a size of 5 mm or less (preferably 1 mm or less) (S140), and secondarily dried to 10% or less of water content (S150).

Thereafter, to increase the cohesiveness in the coffee parchment, the adhesive component such as gelatin is added to the total weight by 0.5-5% (preferably 1-2%) to perform the cohesive increase step (S155), and then perform the pressing step. (S160).

In this pressing process, the parchment lacks fluidity, so that the pallet is easily discharged by spraying water into the mold.

Through the pressing process, a fuel pellet having a predetermined size is obtained (S170).

Molding is carried out in the same manner as in Example 1-3, but the molding is molded into a briquette type, not pellets.

The fuel pellets and briquettes thus obtained must satisfy certain conditions in order to have value as BIO SRF (Solid Refuse Fuel), which will be described in detail below.

FIG. 9 is a diagram illustrating an SRF reference table which is a standard for determining performance of fuel pellets including a coffee parchment according to an embodiment of the present invention, and is based on the Law on Saving Resources and Promoting Recycling. And SIO and BIO SRF (Bio Solid Refuse Fuel).

As shown in Figure 9, compared to the general SRF BIO SRF it should be seen that the content of ash (ashes) should be less, and the content of heavy metal components such as lead should be low.

As shown in FIG. 10, the fuel pellet including the coffee parchment according to the embodiment of the present invention is 5.4% of ash content after combustion of 15% or less of the total weight, and 5.9% of water content of 10% of the total weight, Low calorific value is also 4120kcal / kg exceeding the minimum standard 3500kcal / kg, and will be said to correspond to the BIO SRF fuel because there is almost no other heavy metal content.

In other words, the fuel pellet including the coffee parchment according to the embodiment of the present invention will be said to have advantages as an environment as well as a fuel value.
