Manufacturing apparatus and method of manufacturing solid fuel using citrus foil {Manufacturing apparatus and method of solid fuel using citrus peel}

The present invention relates to a solid fuel manufacturing apparatus and a manufacturing method using a citrus foil, and more particularly, after removing the water contained in the oil splashing method for citrus foil, which is a by-product generated in the citrus processing process, water removal process The present invention relates to a solid fuel manufacturing apparatus and a manufacturing method using a citrus foil to extract the oil contained in to prepare a citrus foil solid, and to be mixed with the citrus foil solid and pork oil to produce a solid fuel.

Recently, with the development of agricultural technology, fruit production such as citrus fruits is also increasing. Due to the increase in production, the price of citrus fruits and the imbalance of supply and demand are continuously generated. To solve these problems, technologies for using citrus fruits for various purposes are being developed. For example, citrus fruits, such as beverages, alcohol, sweets, cosmetics, pharmaceuticals, etc., which have citrus fruits as their main ingredients, have been produced while undergoing an appropriate processing process for citrus fruits.

However, in such a citrus processing process, the generation of citrus gourds including citrus peels and debris is also increasing. Citrus gourds generated in the citrus processing process contain about 80% or more moisture.

In order to finally process the citrus gourd generated in the citrus processing process, various methods such as landfilling, ocean dumping, incineration, feed, fueling have been proposed. Although such a conventional treatment method has a different method, it has a common purpose of reducing the water content and preventing environmental pollution.

Onshore landfilling is a case where the citrus gourd having a water content of 80% or more is directly buried in the soil, and there are problems in securing landfill and secondary pollution. And dumping at sea also has the problem of polluting the ocean and thus cannot be an adequate countermeasure. Incineration methods are discussed as alternatives to landfill or ocean dumping, but incineration treatment is disadvantageous for resource recovery, and local residents' opposition to the construction of incinerators and enormous operating costs due to high water content are problematic.

As noted above, it would be best to recycle energy and resources by recycling them rather than simply landfilling, dumping, incineration. This technology has already been studied in developed countries, some of which have been put to practical use. Examples of the reuse method of the citrus gourd include livestock feed and solid fuel. Among them, the present invention relates to a technology for recycling citrus gourd into solid fuel.

However, in order to manufacture solid fuels using citrus foils, since the moisture content of citrus gourds is too high, it is necessary to develop a drying method that can appropriately lower the moisture content of citrus gourds. The problem of not high should be solved.

In addition, a number of livestock processing plants are operating in Korea, and a huge amount of livestock processing residues (bone, fat, internal organs, leather, etc.) are generated every year in these livestock production Songsong factories.

As such, the livestock processing residue generated in the livestock product processing process is a by-product having a very high protein content, and when such by-products are left or landfilled as it is, odors and leachate are generated, which has a huge adverse effect on environmental pollution. Therefore, various designs for efficiently treating such livestock processing residues have been developed.

Particularly, among the livestock products, the processed pig residues generated during the slaughter or processing of pigs have a higher waste area and contain higher fat than other livestock products such as cows and chickens. It is highlighted.

In recent years, a process of extracting pork oil from such processed pork residues containing high fat has been developed and commercialized. As a main raw material, pig oil extracted from citrus gourd and pork processed residues generated in the citrus processing process is used as a main raw material. Development of fuel resources is required.

And solid fuel production method using a citrus fruit foil according to the present invention, the first step of heating the oil to a high temperature capable of vapor evaporation; A second step of introducing citrus fruit into the heated oil; A third step of agitating the citrus fruit paste put into the heated oil with a rotating stirrer to break it into small particles, and frying it with heated oil to evaporate the water contained in the citrus fruit paste with water vapor; A fourth step of extracting the oil contained by compressing the solid evaporated moisture; A fifth step of transferring the oil extracted in the fourth step to a first step process; A sixth step of preparing a citrus gourd-oil dough by mixing the solids extracted with oil and the pork oil extracted from the processed pork residue; And a seventh step of forming the solid fuel of the pallet structure by compressing the citrus foil-oil dough.

According to the solid fuel manufacturing apparatus and manufacturing method using a citrus fruit foil according to the present invention having the configuration as described above, most of the moisture contained in the citrus fruit can be removed by evaporation with water vapor in the process of frying in oil, citrus It is possible to greatly lower the moisture content of the gourd.

Moreover, according to this invention, the oil contained in the citrus gourd solid content from which water was evaporated can be extracted more efficiently.

In addition, according to the present invention, by producing a solid fuel by mixing the citrus gourd solids with pork oil, it is possible to recover energy and resources through environmentally friendly recycling of citrus gourds and processed pig residues, the environment according to marine dumping of citrus gourds Pollution can be prevented.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the solid fuel production apparatus and manufacturing method using a citrus fruit foil according to the present invention.

1 shows a configuration of a solid fuel production apparatus using a citrus fruit foil according to the present invention, Figures 2 to 4 are shown the configuration of an oil extractor in the solid fuel production apparatus according to the present invention, Figure 5 Solid fuel production method using a citrus foil according to the invention is shown.

Referring to Figure 1, a solid fuel manufacturing apparatus using a citrus foil, a hopper 10 to which the citrus foil is put, and a moisture remover 20 to fry the citrus foil transferred from the hopper 10 with high temperature oil to remove moisture. The oil extractor 60 extracts the oil contained in the solid by squeezing the citrus gourd solids (hereinafter referred to as `` solids '') whose moisture is evaporated in the water remover 20, the solids extracted from the oil and the pigs extracted from the processed pig residues. It comprises a dough mixer 70 for mixing citrus oil-oil dough by mixing the oil, and a molding machine 80 for pressing the citrus fruit-oil dough into a solid fuel of a pallet structure.

In addition, before the solids discharged from the water remover 20 are immediately sent to the oil extractor 60 to extract the oil contained therein, it is preferable to be configured to extract some oils in advance as follows.

To this end, the solid fuel manufacturing apparatus using a citrus fruit foil according to the present invention, the mesh separator 30 for filtering out the relatively fine solids and oil from the solids and oil discharged from the water remover 20, the mesh separator 30 In the centrifuge (40), which separates only oil from the fine solids and oil again filtered out, the relatively large solids not filtered out of the mesh separator (30) and the relatively fine solids separated from the centrifuge (40) are temporarily stored. After that, it is preferable to further comprise a temporary storage (50) for transferring to the oil extractor (60).

In addition, the hopper 10 into which the citrus foil is put has a large space therein so that a large amount of citrus foil can be put therein, and a relatively large inlet is formed in the upper portion thereof, and a lower amount of the citrus foil can be discharged in the lower portion thereof. As a result, small outlets are formed. Therefore, a large amount of citrus fruit can be put at the same time into the hopper 10, the citrus fruit put into the hopper 10 is configured to be continuously transferred to the water remover 20 only a certain amount.

And a large amount of oil is stored in the moisture remover 20, the oil stored in the moisture remover 20 is heated to a high temperature capable of vapor evaporation. Therefore, the citrus foil transported from the hopper 10 to the moisture remover 20 is fried by oil heated to a high temperature, and in the process, most of the moisture contained in the citrus foil is evaporated and removed.

At this time, when the citrus foil is fried as it is, only the outside of the citrus foil is fried, the inside of the citrus foil may not be fried, and in this case, the moisture may remain inside the citrus foil. In order to prevent this, in the present invention, a stirrer (not shown) is installed inside the water remover 20 to rotate in a horizontal or vertical direction, and the citrus foil is decomposed into small particles by the rotating stirrer. It is desirable that all of them be fried in oil so that moisture can evaporate.

And the water removed from the citrus foil is evaporated in the form of water vapor, the vaporized water vapor is discharged to the outside by a fan (not shown) for sucking the internal air to the outside. At this time, the water vapor discharged to the outside is preferably condensed by water at room temperature, it is preferably configured to be discharged to the waste water.

As such, among the citrus meal solids and oils of various sizes discharged from the water remover 20, the relatively fine solids and oil are filtered out by the mesh separator 30, and the relatively large solids are not filtered out. It is transferred to) and stored temporarily. As such, the mesh separator 30 is formed of a screen structure of a mesh type so as to separate solids and oil according to size.

That is, while solids and oils of various sizes discharged from the water remover 20 pass through the mesh separator 30 of the screen structure, the solids large enough to not pass through the screen are temporarily filtered without being filtered out of the mesh separator 30. The solids and oil that are fine enough to be transferred to the reservoir 50 and pass through the screen are passed through the screen of the mesh separator 30 and filtered down.

As such, the temporary storage 50 is a device in which relatively large solids not filtered out in the mesh separator 30 and relatively fine solids separated in the centrifuge 40 are temporarily collected and stored together. And the solids are temporarily stored in the temporary storage (50), because a certain amount of solids must be collected together to be transferred to the oil extractor (60) to be pressed into the compression process.

A certain amount of solids collected in the temporary storage 50 is transferred to the oil extractor 60 to undergo a compression process, the oil contained in the solid content is extracted through this compression process. The oil extracted from the oil extractor 60 is transferred to the water remover 20 again and joined to the oil splashing citrus fruit and recycled.

At this time, the second piston 66 is moved forward to close one side of the cylinder 63, it is preferable that the solid content introduced into the cylinder 63 is not configured to escape to the outside.

As shown in FIG. 3, the first piston 65 is moved forward in the cylinder 63 in the direction of the second piston 66 to compress the solids to extract oil from the solids. At this time, the oil extracted from the compressed solid content (B) exits the cylinder 63 through the deoiling hole (64).

As shown in FIG. 4, after all of the oil is extracted from the solids by pressing the first piston 65 and the second piston 66, the second piston 66 is moved backward to move the cylinder 63. One end is opened, and then the first piston 65 is moved forward to discharge the solids B from which oil is extracted to the outside of the cylinder 63.

And the oil extracted from the solid through the compression and exited to the outside of the cylinder 63 is transferred to the process of frying the first citrus gourd is joined to the oil frying the citrus gourd is recycled (S26).

And citrus gourd solids discharged from the oil extractor and pork oil extracted from the pig processing residue is mixed to produce a citrus gourd-oil dough (S28). At this time, the amount of citrus gourd solids and pork oil to be prepared for the production of citrus gourd-oil dough is preferably set at a ratio of about 7 to 3.

Then, the citrus foil-oil dough is pressed to form a solid fuel having a pallet structure (S30), and the oil of the process of frying citrus foil is heated using the solid fuel generated here as an exothermic fuel (S32).

In other words, the solid fuel of the pallet structure formed by pressing the citrus fruit-oil dough is used as an exothermic fuel for heating the oil, and the oil heated using the solid fuel is used to evaporate the moisture contained in the citrus fruit foil.
