Meanwhile, the second shaft 255d may be rotatably supported by the second shaft bearing 235d provided in the motor bracket 251d and the drum rotating shaft portion 234d.

In the above structure, as shown in FIG. 9 , the first shaft 236d formed on the drum rotating shaft portion 234d of the grinding drum 230d is a first shaft bearing 222d provided on the first shaft support portion 220d. ), the second shaft 255d of the driving part 250d provided through the first shaft is provided in the second shaft shaft hole 232d of the motor bracket 251d and the drum rotation shaft part 234d. It is rotatably supported by the second shaft bearing 235d.

Between the first shaft support part 220d and the first shaft 236d, the first shaft 236d is rotatably supported in only one direction (or the other direction) with respect to the first shaft support part 220d in a first direction. A bearing 238d is provided, and between the second shaft 255d and the first shaft 236d, the second shaft 255d is rotatable only in the other direction (or one direction) with respect to the first shaft 236d. A second one-way bearing 256d for supporting may be provided.

In the case of the food processing apparatus 10d according to the fifth embodiment of the present invention, when the food waste is pulverized, the food waste inside the grinding drum 230d is pulverized by the rotation of the pulverizing blade 240d, and the pulverizing blade 240d). After the food wastes are pulverized by the

In more detail, as food waste and water are fed together into the grinding drum 230d, the motor 252d of the driving unit 250d is rotated in one direction to operate, and the second connected to the rotor 254d of the motor 252d The shaft 255d rotates with the rotor 254d. At this time, the blade hub 241d of the grinding blade 240d connected to the second shaft 255d is rotated along with the second shaft, and the grinding drum 230d by the blades 242a and 242bd provided in the blade hub 241d. Food waste that has been put into the machine may be crushed.

The second shaft 255d of the motor 252d is rotatably supported by the second shaft bearing 235d with respect to the first shaft 236d and is positioned between the second shaft 255d and the first shaft 236d. Rotation in one direction (or the other direction) is possible by the provided second one-way bearing 256d, and rotation in the other direction (or one direction) may be limited.

Accordingly, when the food wastes introduced into the grinding drum 230d are crushed, the rotation direction of the motor 252d is rotated in only one direction, so that only the grinding blade 240d is rotated.

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

Here, as the motor 252d is rotated in the opposite direction to one direction, the second shaft 255d of the motor 252d is rotated in the other direction opposite to the one direction, and the second shaft 255d is rotated in the other direction. Accordingly, the second shaft 255d and the first shaft 236d may be rotated together in the other direction by the first one-way bearing 238d provided between the second shaft 255d and the first shaft 236d.

Therefore, when the motor 252d is rotated in the other direction, the drum 231d of the grinding drum 230d and the blades 242ab and 242bd of the grinding blade 240d are rotated in the same direction, and inside the drum 231d The pulverized food waste and water may adhere to the inner wall of the drum 231d by the rotational centrifugal force of the drum 231d.

In addition, in the case of the above-described first one-way bearing 238d, when the second shaft rotates in one direction, the first shaft 236d is caused by the contact inertia between the second shaft 255d and the second one-way bearing 256d of the motor. Rotation along the inlet direction can be prevented.

The fastening state of the second shaft 255d and the first shaft 236d by the first one-way bearing 238d and the second one-way bearing 256d as described above is individually applied to the other embodiments of the present invention described above. It can also be implemented, and if the drum 230d and the grinding blade 240d are individually formed in a rotatable food processing apparatus, it can be said that they are included in the scope of the present invention.

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

Hereinafter, the separation and discharge means will be described in detail with reference to FIG. 11 .

Figure 11 (a) illustrates the formation of the separation and discharge means (260d) by directly processing the inner peripheral surface of the drum (231d) on the surface of the drum (231d) itself.

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

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

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

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

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

Here, in the case of the inner circumferential surface of the drum 231d, the water is formed as an inclined surface 231ad that is inclined outward toward the upper portion of the drum 231d and moved to the drain groove 263d by the centrifugal force of the drum 231d. 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 261d and the drain groove 263d are formed on the inner circumferential surface of the drum 231d through processes such as grinding, laser processing/etching, and the like. That is, drainage grooves 263d at predetermined intervals are formed on the inner peripheral surface of the drum 231d through a process such as grinding, laser processing/etching, etc., and the inner peripheral surface of the drum 231d in which the drainage grooves 263d are not formed is a drainage protrusion. (261d) may be formed.

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

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

In addition, the surface of the drain protrusion 261d (that is, the inner circumferential surface of the drum 231d) has a water repellent layer 262d so that water contained in the food wastes in close contact with the inner circumferential surface of the drum 231d can smoothly flow into the drain groove 263d. ) may be further formed.

Here, the water-repellent layer 262d may be formed on the surface of the drain protrusion 261d (that is, the surface d forming the inner circumferential surface of the drum 231d), and may be formed by forming the surface roughness of the drain protrusion 261d. have. Here, the water-repellent layer 262d may be formed by setting the surface roughness of the drain protrusion 261d to Ra=2-3.

Alternatively, the water-repellent layer 262d may be formed at the end of the drainage projection, and on the surface of the drainage projection 261d (that is, the surface d forming the inner circumferential surface of the drum 231d) in the direction of the rotation axis of the drum 231d. It may be formed as a hairline pattern (not shown) extending to Here, when the water-repellent layer 262d is formed in a hairline pattern, it may be formed to have an interval of 6-8 μm.

On the other hand, the water-repellent layer 262d as described above may be formed first on the inner wall of the drum 231d before the separation and discharge means 260d are formed, and the water-repellent layer is formed after the water-repellent layer 262d is formed. By processing the inner surface of the separation discharge means (260d) may be formed.
