On the other hand, in the above structure, as shown in FIG. 2 , the outer shaft 236 formed on the drum rotating shaft part 234 of the dewatering drum 230 is rotated by the outer shaft bearing 222 provided in the outer shaft support part 220 . The inner shaft 255 of the driving unit 250 provided through the outer shaft and supported as much as possible is rotated by the inner shaft bearing 235 provided in the inner shaft hole 232 of the motor bracket 251 and the drum rotating shaft portion 234 . possibly supported.

In addition, a first one-way bearing 238 is provided between the outer shaft support 220 and the outer shaft 236 so that the outer shaft 236 is rotatably rotatable in only one direction (or the other direction) with respect to the outer shaft support portion 220, A second one-way bearing 256 may be provided between the inner shaft 255 and the outer shaft 236 to rotatably support the inner shaft 255 in the other direction (or one direction) with respect to the outer shaft 236 .

On the other hand, in the case of the food processing apparatus 10 of the present invention, when the food waste is pulverized, the food waste inside the dewatering drum 230 is pulverized by the rotation of the pulverizing unit 240 , and the food waste is pulverized by the pulverizing unit 240 . After the food is pulverized, moisture may be removed from the pulverized food waste by the rotation of the dewatering drum 230 .

In more detail, the motor 252 of the driving unit 250 rotates in one direction as the food waste and water are fed into the dewatering drum 230, and the inner shaft connected to the rotor 254 of the motor 252 ( 255 is rotated like the rotor 254 . At this time, the blade hub 241 of the grinding unit 240 connected to the inner shaft 255 is rotated along with the inner shaft, and food residues are fed into the dewatering drum 230 by the blades 242a and 242b provided in the blade hub 241 . can be crushed.

Accordingly, when the food wastes fed into the dewatering drum 230 are pulverized, the rotation direction of the motor 252 is rotated in only one direction so that only the pulverizer 240 is rotated.

Meanwhile, when the grinding of the food waste inside the dewatering drum 230 is completed by the pulverizing unit 240 , the dewatering drum 230 may be rotated to separate moisture contained in the pulverized food waste. In this case, the driving unit 250 may rotate the rotation direction of the motor 252 in a direction opposite to the direction when the food waste is crushed.

Here, as the motor 252 is rotated in the opposite direction to one direction, the inner shaft 255 of the motor 252 is rotated in the other direction opposite to the one direction, and as the inner shaft 255 is rotated in the other direction, the inner shaft 255 is rotated in the other direction. ) and the outer shaft 236 by the first one-way bearing 238 provided between the inner shaft 255 and the outer shaft 236 can be rotated together in the other direction.

Accordingly, when the motor 252 is rotated in the other direction, the drum 231 of the dewatering drum 230 and the blades 242a and 242b of the grinding unit 240 rotate in the same direction, and inside the drum 231 The pulverized food waste and water may adhere to the inner wall of the drum 231 by the rotational centrifugal force of the drum 231 .

In addition, in the case of the aforementioned first one-way bearing, when the inner shaft rotates in one direction, it is possible to prevent the outer shaft from rotating in the mouth direction due to the contact inertia between the inner shaft of the motor and the second one-way bearing.

On the other hand, food waste and water, which are in close contact with the inner wall of the drum 231 due to the rotation of the drum 231 , are separated from the food waste and water by the separating and discharging means 260 , 270 , 280 formed on the inner circumferential surface of the drum 231 . can be separated.

3 to 4 , separation and discharging means 260 , 270 , 280 continuously formed along the inner circumferential surface of the drum 231 of the dewatering drum 230 may be provided on the entire inner circumferential surface.

The separation and discharging means 260 , 270 , 280 form panels arranged at predetermined intervals on the inner circumferential surface of the drum 231 , and the food residues pulverized by the pattern formed by the separation and discharging means 260 , 270 , 280 . and water may be separated and discharged.

Figure 4 (a) illustrates the formation of the separation discharge means 260 by directly processing the inner peripheral surface of the drum 231 on the surface of the drum 231 itself.

As shown, the separating and discharging means 260 may be formed of a plurality of drain protrusions 261 protruding and formed, and drain grooves 263 formed between each drain protrusion 261 .

Here, the drain protrusion 261 may prevent food waste from flowing into the drain groove 263 when the food waste inside the drum 231 is in close contact with the inner wall of the drum 231 as the drum 231 is rotated. .

In addition, the drain groove 263 may form a flow path through which water separated from the food waste by the centrifugal force according to the rotation of the drum 231 from the food waste closely adhered to the inner circumferential surface of the drum 231 moves.

Here, the width of the drainage groove 263 may be formed to be smaller than the food waste crushed by the crusher 240 , and the width of the drainage protrusion 261 is different. It may be formed to be larger than the width of the drain groove 263 .

Accordingly, the movement of food wastes in close contact with the inner circumferential surface of the drum 231 toward the drain groove 263 may be restricted by the drain protrusion 261 of the separating/discharging means 260 , and water may be discharged to the drain protrusion 261 . It may be separated by centrifugal force from the mounted food waste and moved to the drain groove 263 .

Here, in the case of the inner peripheral surface of the drum 231 , the water moved to the drain groove 263 is formed as an inclined surface 231a that is inclined outward toward the upper part of the drum 231 by the centrifugal force of the drum 231 . can be moved to the top of the

On the other hand, the separation and discharging means as described above is one in which the drain protrusion 261 and the drain groove 263 are formed on the inner circumferential surface of the drum 231 through a process such as grinding, laser processing/etching, and the like.

Meanwhile, the width D1 of the drain protrusion 261 is preferably formed to be larger than the width D2 of the drain groove 263 . The pulverization size of the food wastes pulverized by the pulverizer 240 may correspond to 300-500 μm, and the width D1 of the drain protrusion 261 is too small, or the width D2 of the drain groove 263 . When this is too large, the pulverized food waste may flow into the drain groove 263 .

Here, the depth of the drain groove 263 may be formed to be about 70-90㎛, preferably formed to be 80㎛. In addition, the width of the drain groove 263 may be formed to be 40-60㎛, preferably may be formed to be 50㎛. Meanwhile, in the drain groove 263 as described above, water contained in the food residues in close contact with the inner circumferential surface of the drum 231 may be introduced by a capillary phenomenon.

On the other hand, when the pulverization of food waste inside the drum 231 is completed, the driving unit 250 rotates in the opposite direction to the rotation direction when pulverizing the food waste inside the drum 231 to proceed with dehydration of the pulverized food. can

Here, as the rotation direction of the driving unit 250 is rotated in the opposite direction when the grinding unit 240 grinds food waste, the inner shaft 255 of the driving unit 250 and the outer shaft 237 of the dewatering drum 230 are It can be rotated together by the second one-way bearing provided between the inner shaft 255 of the driving unit 250 and the outer shaft 237 of the dewatering drum 230 .

Accordingly, the food wastes pulverized inside the drum 231 are in close contact with the inner circumferential surface of the drum 231 by the rotational centrifugal force of the drum 231 , and the food wastes in close contact with the inner circumferential surface of the drum 231 are on the inner circumferential surface of the drum 231 . Food waste and water may be separated and dehydrated by the formed separation and discharging means 260 , 270 , and 280 .

Here, the water separated from the food waste by the rotation of the drum 231 is moved to the upper outer circumferential surface of the drum 231 and scattered to the outside of the drum 231 and separated, and the scattered water is separated from the drain chamber 210 . may be moved to the lower part of the and drained through the drain pipe 218 connected to the lower part of the drain chamber 210 .
