Therefore, the terms used in the present invention should be defined based on the meaning of the term and the overall content of the present invention, rather than simply the name of the term.

When it is said that a part of the entire invention "includes" a certain component, this means that, unless specifically stated to the contrary, it does not exclude other components but may further include other components. Additionally, terms such as “…unit” and “…module” used in the specification refer to a unit that processes at least one function or operation, which may be implemented as hardware or software, or as a combination of hardware and software.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

Figure 1 shows the approximate configuration of a food waste treatment device using a plurality of stirrers and microorganisms according to the present invention, and Figure 2 shows a first food waste treatment device using a plurality of stirrers and microorganisms according to the present invention. This is an example.

The food waste treatment device using a plurality of stirrers and microorganisms according to the present invention largely includes a primary agitation device 110, a secondary agitation device 120, a decomposed material storage member 130, a rotation drive device 140, and a decomposed material discharge device. It can be implemented including (150).

As shown in FIG. 2, the primary stirring device 110 includes a first stirring vessel 111 in which a first stirrer module is installed.

The primary agitation device 110 is a place where food waste is primarily decomposed and treated. Powder or liquid microbial cultures (e.g., sawdust) are contained in the first agitation container 111 of the primary agitation device 110. , rice husk, buckwheat flour, microbial culture medium, etc.) and food waste are input together.

At this time, the microorganisms contained in the microbial culture are mixed with food waste during stirring and play the role of decomposing and treating organic matter in the food waste.

The first stirrer module stirs and pulverizes the microbial culture and food waste, and in this process, the microorganisms decompose the stirred and pulverized food waste.

In addition, the first stirrer module installed inside the stirring container 111 of the primary stirring device 110 is spaced apart from a rotating shaft installed at a certain distance from the bottom surface of the stirring container 111 and a portion of the rotating shaft. It includes a plurality of stirring blades.

Meanwhile, the secondary stirring device 120 may include a stirring vessel 121 in which a second stirrer module is installed, as shown in FIG. 2.

The first decomposed product containing microorganisms, which is stirred and pulverized in the primary stirring device 110, is introduced into the stirring container 121 of the secondary stirring device 120.

The first decomposition product that has undergone the above-described decomposition process can be reintroduced from the primary stirring device 110 to the secondary stirring device 120.

The second agitator module stirs the first decomposed product and further completely decomposes the first decomposed product by microorganisms contained in the microbial culture and food waste to generate a final decomposed product and discharges it to the decomposed product storage member 130. The amount of this final decomposition product may be significantly less than the amount of the first decomposition product.

The present invention improves the decomposition ability by further decomposing the first decomposition product through the first agitation through the second agitation, just as a ruminant animal maximizes digestion power and minimizes residual matter by chewing the cud using multiple stomachs. The amount of decomposition can be increased by first stirring new food waste while secondary stirring is taking place.

In addition, even after primary agitation and primary decomposition using microorganisms, a large amount of microorganisms are contained in the microbial culture and food waste. Conventionally, all of them had to be discarded, but in the present invention, they are used for secondary agitation and decomposition. By using it as a material, secondary stirring and decomposition can be effectively performed without adding additional microorganisms.

A heating member may be formed on the inner wall of the incoming air supply pipe.

The operation of the exhaust fan causes circulation of air outside and inside the stirring vessel, so hot air generated inside the stirring vessel is discharged to the outside through the exhaust pipe, and external air flows into the stirring vessel through the supply pipe. Accordingly, aerobic microorganisms or anaerobic microorganisms that are mixed with microbial cultures and food waste can maintain a constant optimal activity temperature of about 37°C.

The decomposed product storage member 130 temporarily stores the final decomposed product discharged from the secondary stirring device 120. The user puts the final decomposed product stored in the decomposed product storage member 130 into a volume-rate bag and discards it.

In fact, the food waste treatment device using a plurality of stirrers and microorganisms according to the present invention leaves almost no final decomposition products of the microorganisms.

This is because microorganisms can maintain an optimal activity temperature of about 37°C in the stirring vessel 111 of the primary stirring device 110 and the stirring vessel 121 of the secondary stirring device 120.

In particular, in the case of the secondary stirring device 120, a sufficient decomposition effect can be obtained simply by maintaining an appropriate survival temperature of microorganisms without adding additional microbial culture.

The rotation drive device 140 may be implemented to include a first motor unit 141 that rotates the rotation axis of the first stirrer module and a second motor unit 142 that rotates the rotation axis of the second stirrer module.

For example, a main pulley is installed in the first motor unit 141 and the second motor unit 142, respectively, and a driven pulley is installed in the first agitator module and the rotation axis of the first agitator module, respectively, and the main pulley and the driven pulley are Can be connected in a chain.

The decomposed product discharge device 150 is installed between the stirring container 111 of the primary stirring device 110 and the stirring container 121 of the secondary stirring device 120, and removes the product processed in the primary stirring device 110. 1 A first decomposed product discharge device 151 that discharges decomposed products to the secondary agitation device 120 and a second decomposed material placement device that discharges the final decomposed products processed in the secondary agitation device 120 to the decomposed material storage member 130 It can be implemented including (152).

Although not shown in FIG. 3, the food waste treatment apparatus using a plurality of stirrers and microorganisms according to the present invention may be implemented including a control console.

The control console may include a control unit that allows the user to control the power on/off of the device and the operation of the exhaust fan, suction fan, container heating unit, and heating member.

The control unit controls the power supplied to the container heating unit using the internal temperature value of the stirring container detected by the temperature sensor and the internal humidity value of the stirring container detected by the humidity sensor.

The control unit controls the driving of the plurality of motor units of the rotation drive device 140. For example, the control unit may control the motor to rotate forward or reverse so that the microorganisms, microbial cultures, and food waste stirred between the plurality of agitator modules installed in the primary agitation device 110 move across each other.

Accordingly, the microorganisms, microbial cultures, and food waste do not stick to the bottom and side walls of the stirring container, and the food waste, microorganisms, and microbial cultures can be well stirred.

Figure 9 is an exemplary diagram for explaining the primary agitation device of the food waste treatment device using a plurality of agitators and microorganisms according to the present invention.

Looking at the configuration of the primary stirring device 610 in more detail with reference to FIG. 9, the primary stirring device 610 is located inside a cylindrical first stirring container 611 arranged in the vertical direction and spaced at a certain distance from the bottom surface. It is configured to include a first rotating shaft 613 that is installed to be used and crushing blades 612 including a plurality of blades 612a formed on the surface of the first rotating shaft 613.

At this time, an air supply pipe (not shown) through which external air flows in may be further installed in the hollow (not shown) of the first rotation shaft 613 of the first stirring device 610 to activate microorganisms.

In addition, a first decomposed product discharge device 651 is coupled to a portion of the bottom of the cylindrical first stirring container 611, so that the first stirring container 611 ) Food waste and microbial cultures (liquid or powder form) introduced into the inside are stirred, pulverized, and decomposed by microorganisms, and then discharged to the lower secondary stirring device (620-1) (620-2).

At this time, a pair of first and second stirring vessels 621 and 622 arranged horizontally side by side are provided inside the secondary stirring devices 620-1 and 620-2, respectively. After the first decomposition product is re-introduced into one or both of the first or second stirring containers (621) (622), it is purified through the secondary stirring devices (620-1) (620-2) and the connection passage (770). 2 As the decomposed product circulates, it is again stirred, dried, and decomposed by microorganisms.

Figure 10 is a diagram showing a state in which the first discharge introduced into the secondary agitator of the food waste treatment device using a plurality of agitators and microorganisms according to the present invention is circulated and agitated, dried, and decomposed by microorganisms.

As described above, the first decomposition product discharged after being processed from the primary stirring device 610 is re-introduced into the secondary stirring devices 620-1 and 620-2 shown in FIG. 10, at which time the secondary The stirring device (620-1) (620-2) includes a pair of first and second stirring vessels (621) and (622) arranged side by side, and a pair of first and second stirring vessels (621) (622). Connection passages 770 for circulation of the second decomposed product are formed at both ends, respectively.

The connection passage 770 is shown in the shape of a pipe according to one embodiment, but is not limited thereto. For example, the holes formed at both ends of the first and second stirring vessels 621 and 622 are connected to each other. By being joined, the first and second stirring vessels 621 and 622 may be directly connected.

At this time, as described above, first and second stirrer modules (741, 742, 743) (751, 752, 753) are provided inside the first and second stirring vessels (621) and (622), respectively. .

More specifically, the first and second stirrer modules (741, 742, 743) (751, 752, 753) have first and second rotation shafts ( 741) (751) are rotatably coupled in a horizontally arranged state, and the first and second rotation shafts 741 and 751 each have screw wings provided for transporting the second decomposed product in one direction or the opposite direction. It is achieved by combining 742) (752) and stirring blades (743) (753).

Therefore, as described above, as the second and third motor units 642 and 643 rotate in opposite directions, the first and second rotation shafts 741 and 751 linked thereto, and the first and second motor units 642 and 643, respectively, rotate in opposite directions. Screw blades 742, 752 and stirring blades 743, 753 formed around the rotation shafts 741 and 751 are positioned within the first and second stirring vessels 621 and 622 while rotating in opposite directions. The second decomposed product forms a closed loop and is transported in one direction to continue circulation.

At this time, the second decomposed product that has reached both ends of the first and second stirring vessels 621 and 622 is connected to the connecting passage 770 by the screw blades 742 and 752 and the stirring blades 743 and 753. ), and in particular, the stirring blades 743 and 753 are formed at both ends of the first and second rotation shafts 741 and 751 to correspond to the connection passage 770, respectively, so that the first The decomposed product is pressurized so that it can escape through the connection passage 770 without stagnation at both ends of the first and second stirring vessels 621 and 622.

Accordingly, the first decomposed product is circulated without stagnation along the first and second stirring vessels 621 and 622 and the connecting passage 770 at both ends during a specific secondary food processing time (e.g., 4 to 8 hours). As stirring, drying, and decomposition by microorganisms continue, it is finally dried and composted in powder form before being discharged.

Therefore, the second decomposed product that reaches both ends of the first and second stirring vessels 621 and 622 through the connecting passage 770 does not stagnate or harden and stick, but continues to circulate and is stirred, dried, and exposed to microorganisms. Since secondary decomposition treatment is carried out, after a certain secondary food processing time, it is possible to obtain high-quality second decomposition material composted in the form of powder with even particles.

The second decomposed product finally discharged in powder form falls to the lower decomposed material storage member 630 and is stored, so it can be beneficially used as organic compost.
