Such a rotation means enables rotation of the stirring drum 10 about the drive shaft of the third motor 90.

1 and 3A, the separation preventing means is fixed in the housing 100 to surround the outer circumferential surface of the stirring drum 10 so that the stirring drum 10 is rotatable, and the food dregs are introduced therein. The cover member 130 is formed with an inlet 131 formed at a position and an outlet 132 formed at a discharge position at which food waste is discharged.

In this case, the sealing member 12 is installed at the edge of the entrance and exit 11 of the stirring drum 10 so that the stirring contact with the cover member 130 when the stirring drum 10 is rotated relative to the cover member 130. It is to be effectively prevented from leaving the food through the doorway (11).

In addition, the treatment apparatus of the present invention, which is located at the center of the stirring drum 10 is rotated relative to the stirring drum 10 together with the eccentric shaft 42, 43, the rotation of the main blade 50 The main shaft 41 which limits the section is provided.

The main shaft 41 is formed in a polygonal shape, as shown in Figure 4 to limit the rotation section of the main braid (50). That is, when the main blade 50 is rotated together when the main shaft 41 and the eccentric shafts 42 and 43 rotate together, a part of the main blade 50 is supported by the main shaft 41 to stir the food waste. And reaction force when crushed.

On the other hand, according to the cross-sectional shape of the main shaft 41 can be configured in a variety of support angles of the main blade 50, according to the efficient positioning by placing the main blade 50 in various positions in the stirring drum 10 And to allow grinding.

In addition, the main blade 50 employed in the processing apparatus of the embodiment of the present invention may be configured in various shapes including a fan shape as shown.

In addition, the apparatus of the present invention is located on both sides of the inside of the stirring drum 10, the auxiliary blades 51 and 52 are coupled to both ends of the main shaft 41 and the eccentric shaft 42, 43, respectively, and rotated. It is provided.

As shown in FIG. 2, the auxiliary braids 51 and 52 have a polygonal cross-sectional structure in which an inclined surface is formed toward the center of the stirring drum 10, so that the food waste is rotated toward the center of the stirring drum 10. Guide to improve stirring efficiency.

In addition, the present invention is rotatably supported in the interior of the stirring drum 10, scraping food residues remaining on the inner wall of the circumferential direction of the stirring drum 10 and the crushing effect through a relative rotational movement with the main blade A scraper 30 having a first scraper 31 for improving and a second scraper 32 for scraping off food residues remaining on both sides of the stirring drum 10, and rotating the scraper 30. The second motor 80 is provided.

On the other hand, the space between the housing 100 and the stirring drum 10 is provided with a duct 120 and a suction fan 121 for discharging the odor discharged through the entrance 11 of the stirring drum 10 to the outside. have.

The food waste treatment apparatus of the above configuration is operated and used as follows.

First, as shown in FIGS. 1 and 3A, in the state in which the entrance 11 of the stirring drum 10 is positioned upward, the opening and closing door 110 of the housing 100 is opened, and the food residues of the stirring drum 10 are opened. Injected through the doorway (11).

Then, as shown in Figure 3b, by driving the third motor 90 to rotate the stirring drum 10 by an angle to close the entrance 11 to the cover member 130. At this time, the entrance 11 is rotated while being in close contact with the cover member 130 due to the sealing member 12, the leakage of food waste is prevented.

In such a state, the main blade 50 and the auxiliary blades 51 and 52 are rotated in one direction by driving the first motor 70 to stir and grind the food waste. At this time, the relative movement between the main blade and the scraper 31, that is, the cutting and crushing action is also actively progressed through the stop of the scraper, low speed forward rotation, reverse rotation. In addition, the auxiliary braids 51 and 52 which are stopped at this time guide the food waste contained in the stirring drum 10 to the central portion while being rotated so that smooth stirring and grinding are performed.

Next, the second motor 80 is driven to rotate the scraper 30 in one direction for a predetermined time (about 5 seconds). At this time, the scraper 30 to scrape the food residues remaining on the inner wall of the stirring drum (10).

Subsequently, the first motor 70 and the second motor 80 are sequentially driven in the opposite directions to repeat the above operation.

After the stirring and grinding work is completed as described above, the third motor 90 is driven to allow the entrance and exit 11 of the stirring drum 10 to the upper position as shown in FIG. 3A, and the heater 60 is operated. By heating the stirring drum 10 and food waste to evaporate moisture.

At this time, by driving the second motor 80, the food waste pulverized through the scraper 30 is stirred to facilitate evaporation of water, and the suction 121 121 is operated to discharge moisture and odor to the outside through the duct 120. Let's do it. During this drying operation, the second motor 80 is driven in the forward and reverse directions to achieve more effective drying.

As such, when the drying of the food waste is completed, the first motor 70 and the second motor 80 are rotated in a state in which the stirring drum 10 is rotated to close the entrance 11 as shown in FIG. 3B. Restart and regrind the dried food debris.

When the pulverization and drying of the food waste is completed as described above, as shown in FIG. 3c, the outlet 11 of the stirring drum 10 is driven out of the cover member 130 by driving the third motor 90. Rotate the stirring drum 10 to match with.

Subsequently, the first and second motors 70 and 80 are driven to be re-stirred and pulverized for about 5 seconds, and the second motor 80 is driven to rotate the scraper 30 to rotate the crushed / dried food waste container ( To 140).

The present invention as described above may be practiced with many modifications without departing from the spirit and scope of the invention.

The present invention as described above has the following advantages.

First, by employing a plurality of eccentric rotation of the main blade and the relative movement between the scraper to improve the stirring and grinding efficiency of food waste to reduce the processing volume and shorten the processing time.

Second, by employing the auxiliary blade formed with the inclined surface guides the food residue to the center portion of the stirring drum to facilitate the stirring and grinding.

Third, the odor generated during drying of food waste is discharged through the suction duct and the duct to prevent the environmental pollution caused by the smell.

Fourth, by making the food waste inlet and outlet the same, food waste of any size that can be inserted is blocked in the middle of discharging, thus eliminating the possibility of stopping operation. In addition, the hygiene is improved by eliminating the passage for transporting the processed food waste so that all the processed food waste can be discharged.

Fifth, by crushing food waste using blades rotated by an eccentric shaft, food waste that cannot be crushed is mixed with food waste and mixed together. To reduce the likelihood of breakdown of food waste or food handler failure.
