First, in the state as shown in Figure 2, the food waste inside the sink (S) penetrates through the drain hole (D) and the inlet (102) into the grinding means 100, that is, into the first grinding space (112 '). Then, the first screw 122 is rotated to push the food waste to the right while compressing and crushing, the first dehydration of the food waste proceeds.

Thereafter, the food crushed first by the first screw 122 is cut while passing through the cutting blade 160, and the food trash passing through the cutting blade 160 flows into the second grinding space 112 ″. Done.

The food waste flowing into the second grinding space 112 ″ is compressed by the second screw 142 to be dehydrated and crushed again, and the food waste dehydrated twice is passed through the drying tube 104. Falling into the drying means 200.

Moisture contained in the food waste dropped into the drying means 200 is heated by the heating element 240 and evaporated to flow into the temporary storage space 320 through the steam discharge pipe 202.

At the same time, the dirt generated from the food waste inside the grinding space 112 is collected by falling into the waste tank 300 through the waste pipe 106.

When dirt is collected in the dirt tank 300, the water level sensor 344 detects the water level inside the dirt tank 300 to generate a signal for the operation of the shutoff valve 346 and the pump P. Done.

In more detail, when the water level detected by the water level sensor 344 is not higher than a preset height, the shutoff valve 346 of the dilution means 340 is opened to supply water into the waste tank 300. With this water supply, dirt is diluted. At the same time, the pump P is in a stopped state.

On the contrary, when the water level detected by the water level sensor 344 is higher than the preset height, the water shutoff valve 346 is shielded to stop the water supply into the dirt tank 300, and at the same time, the pump P Is operated to force the diluted dirt in the waste tank 300 upward.

By the pumping action of the pump (P), the dirt is introduced into the mixing unit 510 after passing through the dirt guide pipe 520 and the dirt mixing pipe 522.

On the other hand, when the on-off valve 536 is opened, the additive liquid L stored in the storage container 502 is supplied to the liquid mixing means 500 through the auxiliary supply pipe 503. The additive liquid L passes through the auxiliary supply pipe 503, the additive guide tube 530, and the additive mixing tube 532 in order and flows into the mixing unit 510.

The dirt introduced into the mixing unit 510 flows through the discharge pipe 540 by its moving speed (inertia). Looking in more detail, the filth flowing through the filth moving tube 302 passes through the filth mixing pipe 522 having a relatively small diameter, and its flow rate is increased, and is ejected at a high speed into the mixing unit 510. do.

At this time, the filth discharged from the filth mixing pipe 522 is guided downward while hitting the inner circumferential surface of the mixing portion 510 of the funnel shape, and moves downward through the discharge pipe 540.

At the same time, the additive liquid L introduced through the additive guide tube 530 passes through the additive mixing tube 532 having a relatively small diameter, and the flow rate thereof is further increased, and then inside the mixing unit 510. Is blown out. The additive liquid L ejected into the mixing unit 510 moves through the discharge pipe 540 while being mixed with the dirt jetted through the dirt mixing pipe 522.

The dirt moving through the discharge pipe 540 flows down to the first purification layer 420 through the connection hose 508, and flows to the left in the first purification layer 420 to the left. It is introduced into the second purification layer 440 through the).

The dirt introduced into the second purification layer 440 flows in the right direction and is filtered with fine foreign matter, and then flows downward through the second flow path 442 to be introduced into the third purification layer 460.

The dirt introduced into the third purification layer 460 is once again purified and then flows to the left to penetrate the third flow passage 462 to fall into the water tank 480.

At this time, the first valve 424, the second valve 444 and the third valve 464 are in an open state and the purification of the dirt using the food waste treatment apparatus is completed through the above process.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

Food waste processing apparatus according to the present invention as described above, and further comprises a cutting blade for finely cutting the food waste on the inner side of the grinding means for grinding and dehydrating the food waste.

Therefore, since the impact generated in the grinding hole during the compression of the food waste in the lump state is reduced, there is an advantage that the breakage of the grinding hole is prevented.

In addition, there is an advantage that the dewatering ability of the foreign matter contained in the food waste is improved by compacting the food waste that is chopped again.

In addition, by providing a plurality of screws on one side of the grinding means and differently formed intervals of the blade formed on the outer peripheral surface of the plurality of screws there is an advantage that the dehydration capacity for food waste is further improved.
