In the kitchens of general households and restaurants, there is a growing interest in food waste disposal as food waste is generated.

Such food garbage is collected in a trash bag or collection bin after being collected in a trash bag or a collection bin, and odors unique to the food garbage are generated, and the moisture of the food garbage is leaked to make the surroundings dirty, .

Conventionally, various methods such as landfill, incineration, extinction, compression, and drying are used to treat the food waste collected in the above-mentioned manner, but they have been wrapped in a plastic bag that does not rot during processing of food waste.

Particularly, as the amount of food waste is introduced, the food waste generated in each piece is put into a small bag, and a small number of small bags are packed in a single bag, and the small bags for discarding food waste are discarded. It is a real reality that is increasing.

Meanwhile, in recent years, in order to reduce the volume of food garbage, a grinder is installed in the sink, and the food garbage is crushed, and then the crushed food garbage is put into the bag of the specific amount or, in some cases, it is thrown away through the sewer pipe.

In the case of disposing of garbage in pulp-based bags, the odor is also a serious problem in the summer due to the storage of food waste in the bag for several days until it is filled with food waste.

Further, when the pulverized food waste is discarded directly through the sewer pipe, there is a problem that the sewer pipe is clogged.

Therefore, the present applicant has developed a food garbage disposal system capable of sanitizing food waste by fermenting the food waste using microorganisms, transporting the food waste to a toilet, and the like without requiring a separate collection process.

The feed tank 10 has a tubular shape having a receiving space therein, and the pulverized food waste 1 finely pulverized by the pulverizer 110 is introduced. Such a feed tank 10 serves the same purpose as the human body.

In the feeding tank 10, a feeding port 11 for feeding pulverized food waste is formed.

A cap 15 for sealingly closing or opening the charging port 11 is detachably provided at the charging port 11.

The fermentation tank 20 has a tubular shape having a receiving space therein and ferments the pulverized food waste 1 supplied from the feed tank 10. The fermenter 20 functions as a small intestine of the human body.

The fermentation agent supply unit 30 provides a predetermined amount of the fermentation agent to the fermentation tank 20 so as to remove the odor while fermenting the pulverized food waste 1 of the fermentation tank 20.

It is more effective that the fermentation agent has odor removal and high temperature resistance. For example, the fermentation agent is composed of a high concentration organic material and a thermophilic hygroscopically resistant filamentous fungus adapted to a high temperature, a filamentous fungus having a high odor usability in consideration of a substrate transition relationship, a substrate decomposition bacteria having a hypertonic and high temperature and broad substrate availability belonging to Bacillus Malodorous microorganisms including malodorous bacteria, thermophilic actinomycetes having adaptability to high concentration organic matter, and thermophilic actinomycetes adapted to high temperatures while being adaptive to high concentration organic matter.

Here, though not shown, the fermentation agent supply unit 30 is provided at the lower end of the hopper of the fermentation agent storing the fermentation agent, and is operated by a screw feeder for feeding the fermentation agent by a predetermined amount, a rotary valve driven by a motor, A solenoid valve or the like may be provided.

As the pulverized food garbage (1) is fermented by the fermentation agent, the volume of the pulverized food garbage (1) is reduced and at the same time, the fermented food garbage (3) is in paste state or semi-solid state such as porridge. It is preferable that the pulverized food waste 1 is fermented for at least 10 hours or more until the pulverized food waste 1 is fermented by the fermentation agent.

On the other hand, a passage 35 through which the pulverized food waste 1 moves is formed between the feed tank 10 and the fermentation tank 20.

The backflow prevention part 40 is provided in the passage 35 between the charging tank 10 and the fermentation tank 20. The backflow prevention part (40) prevents the odor generated in the fermentation tank (20) from flowing back to the charging tank (10).

The backflow prevention portion (40) includes a stretching member (41) and an elastic member (45).

The stretchable member 41 is made of a stretchable material and protrudes along the inner periphery of the passage 35 toward the center axis of the passage 35 and expands and contracts in the radial direction of the passage 35.

The elastic member 41 is in a closed state in which the peripheral ends of the elastic members 41 facing the central axis of the passage 35 come into contact with each other to close the passages 35 as shown in Fig. , The peripheral end portions of the elastic members 41 facing the center axis of the passage 35 are separated from each other and deformed into the passage opening state in which the passage 35 is opened as shown in Fig. 2 (b).

The elastic member 45 is accommodated in the elastic member 41 and generates an elastic force to the elastic member 41 so that the elastic member 41 maintains the passage closed state.

Therefore, when the weight of the pulverized food waste 1 charged into the feed tank 10 and acting on the stretching member 41 is less than a predetermined value, the stretching member 41 is pulled by the elastic force of the elastic member 45 , The passage 35 is closed, that is, the elastic member 41 is deformed into the passage closed state.

On the other hand, when the weight of the pulverized food waste 1 charged into the feed tank 10 and acting on the stretchable member 41 exceeds a predetermined value, the stretchable member 41 moves in the direction of the axis 35 of the stretchable member 41, The crushed food garbage 1 charged into the charging tank 10 is released from the passage 35 by opening the passage 35 while the peripheral ends of the crushing chamber 41 are separated from each other, And the elastic member 41, and flows into the fermentation tank 20.

The backflow prevention portion 40 opens and closes the passage 35 between the charging tank 10 and the fermentation tank 20 and prevents the odor generated in the fermentation tank 20 from flowing back to the charging tank 10 do.

The discharge guide pipe 50 has a pipe shape in which a receiving space is formed and discharges fermented food waste 3 in a paste state or semi-solid state fermented in the fermentation tank 20 to the toilet 90. The discharge guide tube 50 serves as the large intestine of the human body.

Preferably, the discharge guide tube 50 is vertically or downwardly inclined to the fermenter 20 and connected to the toilet 90. Accordingly, the pulverized food waste 1 flowing into the fermentation tank 20 is not directly introduced into the discharge guide pipe 50 but is fermented, and is transformed into the fermented food waste 3 in the face-like state like porridge, And flows into the pipe 50.

The compressed air supply unit 60 supplies compressed air to the fermentation tank 20 and discharges the fermented food waste 3 of the fermentation tank 20 to the toilet 90 through the discharge guide pipe 50.

Here, although not shown, the compressed air supply unit 60 may be provided with a solenoid valve operated by a motor or a hydraulic pressure. The compressed air supply unit 60 periodically supplies a predetermined amount of compressed air to the fermentation tank 20, for example, a predetermined amount of compressed air once a day into the fermentation tank 20, as if the human body regularly performs defecation, .

The expansion and contraction opening and closing unit 70 is provided on the discharge port 55 of the discharge guide pipe 50 so as to be relaxed and contractible and opens or closes the discharge port 55 as the compressed air is supplied to the fermentation tank 20. The extension / retraction opening / closing unit 70 serves as the anus of the human body.

The expansion / contraction opening / closing portion 70 is made of a stretchable material including a shape memory alloy and is provided along the inner circumferential direction of the discharge port 55 which is in the distal end portion of the discharge guide pipe 50.

3 (a), the expansion / contraction opening / closing portion 70 is formed so that the peripheral edge portion of the expansion / contraction opening / closing portion 70 protrudes along the inner periphery of the discharge port 55 toward the central axis of the discharge guide pipe 50, 3 (b), the circumferential end portions of the expansion and contraction opening portion 70 are spaced apart from each other and are extended toward the outside of the discharge port 55, that is, , And is loosened and transformed into an open state in which the discharge port (55) is opened.

Therefore, when the compressed air is supplied to the fermentation tank 20 by the compressed air supply unit 60, the fermented food waste 3 of the fermentation tank 20 is discharged from the fermentation tank 20 to the discharge guide pipe 50 by the pressure of the compressed air, And presses the expansion / contraction opening / closing portion 70 to open. The expansion and contraction opening 70 is deformed into an open state and the fermented food waste 3 flows into the toilet 90 connected to the discharge guide pipe 50 through the expansion and contraction opening 70 and discharged to the outside .

On the other hand, when the compressed air is not injected into the fermentation tank 20, as the pressure acting on the expansion and contraction portion 70 is reduced, the expansion and contraction portion 70 is rotated by the restoring force of the shape memory alloy, Protrude along the inner periphery of the discharge port 55, come into contact with each other, and are deformed into a closed state. Thus, the fermented food waste 3 contained in the fermentation tank 20 and the discharge guide pipe 50 is not discharged to the outside through the discharge port 55.

In addition, the food garbage disposal system according to an embodiment of the present invention further includes a cleaning unit 80 for cleaning the expansion / contraction opening / closing unit 70. Such a cleaning unit 80 serves as a bidet for cleaning the anus of the human body.

The cleaning section 80 has a jetting section 81 for jetting a cleaning liquid toward the stretch opening and closing section 70 and is provided adjacent to the discharge port 55 of the discharge guide tube 50.

When the fermented food waste 3 is discharged through the discharge port 55 and the expansion and contraction portion 70 is deformed into the closed state, the cleaning portion 80 blows the cleaning liquid toward the expansion and contraction portion 70, . As a result, it is possible to manage the expansion / contraction opening / closing unit 70 cleanly.

The pulverized food garbage 1 finely ground through the pulverizer 110 is charged into the charging tank 10 and the pulverized food garbage 1 which acts on the stretching member 41 of the backflow prevention part 40 , The stretchable member 41 is deformed into the passage open state and the pulverized food waste 1 charged into the feed tank 10 is freed from the passage 35 and the stretching member 41 And flows into the fermentation tank 20.

When the weight of the pulverized food waste 1 acting on the stretchable member 41 is less than a predetermined value, the stretchable member 41 is deformed and restored to the path closed state so that the pulverized food waste 1 is removed from the fermentation tank 20, The odor generated during the fermentation of the fermentation broth does not flow back into the feed tank 10.

The pulverized food waste 1 flowing into the fermentation tank 20 is fermented by the fermentation agent supplied through the fermentation agent supply unit 30 so that the volume of the pulverized food waste 1 is reduced and the paste is in a state of paste or semi- Fermented food waste (3).

When the fermentation is completed in the fermentation tank 20 for a predetermined period of time, when the compressed air is supplied to the fermentation tank 20 by the compressed air supply unit 60, the fermented food waste 3 of the fermentation tank 20 The fermented food waste 3 passes through the extrusion opening and closing part 70 and is discharged to the discharge guide pipe 50. The fermented food waste 3 is then discharged from the fermentation tank 20 through the discharge guide pipe 50, And then discharged to the outside.

When the fermented food waste 3 contained in the fermentation tank 20 and the discharge guide pipe 50 is discharged to the pot 90 and then the compressed air is not injected into the fermentation tank 20, The expansion and contraction opening and closing part 70 contracts due to the restoring force of the shape memory alloy and deforms into a closed state so that the fermentation tank 20 and the discharge guide pipe 50 become hollow.

Thus, one cycle of the food garbage disposal using the food garbage disposal system according to one embodiment of the present invention is completed.

As described above, according to the present invention, the food waste is treated by applying the principles of food digestion and defecation of the human body, so that the food waste is fermented using microorganisms without being subjected to a separate collection process, So that it is not only hygienically processed but also improves the user's convenience.
