1 and 2 are views showing a food waste disposal apparatus according to an embodiment of the present invention. The food waste disposal apparatus 1 according to the present embodiment includes a main body A screw rod 3 connected to the motor shaft of the main motor 2 and rotated to connect the screw blades 31 to the outer circumferential surface of the screw rod 3 so as to transfer the fluid, 31), and has a plurality of through-holes formed therein, and has an inlet hole (41) through which food waste is introduced into one side of the upper side and a discharge hole (41) through which food garbage is discharged A drainage tank 5 in which the drainage pipe 4 is disposed and the drainage hole 51 is formed on the bottom surface of the drainage pipe 4; And a hopper (6) adapted to supply food waste to the charging hole (41) .

That is, as shown in FIG. 2, when the crushing motor 71 is driven in a state where food waste is stored in the hopper 6, the food is crushed in the hopper 6.

After the food waste is crushed in the hopper 6, food waste is introduced into the inlet hole 41 of the dewatering pipe 4, and when the main motor 2 is driven, As the rod 3 rotates, the screw blades 31 are rotated and the food waste is dehydrated while being transported in the direction of the discharge hole 42 from the charging hole 41. The dehydrated discharged water is discharged to the dehydrating pipe 4 And is received in the drain tank 5 while dropping naturally.

The drainage water stored in the drainage tank 5 is discharged to the outside through the drainage hole 51 of the drainage tank 5 and treated.

On the other hand, the food waste which has been dehydrated while being conveyed inside the dewatering pipe 4 is discharged to the outside through the discharge hole 42, stored in a storage container (recovery bag) not shown, and then treated separately.

The hopper 6 is preferably provided with a crushing means 7 for crushing the food supplied from the outside so as to supply the crushed food waste to the charging hole 41 after crushing the food waste; The crushing means 7 includes a crushing motor 71 fixed to the hopper 6 and adapted to rotate the rotation shaft by receiving power, a crushing motor 71 connected to the crushing motor, And a crushing rod 72 having crushing blades 73 formed thereon.

That is, when the crushing motor 71 is driven, the crushing rod 72 rotates and the food waste stored in the hopper 6 is crushed by the crushing blades 73, .

As a result, dehydration of water contained in the food garbage is performed more smoothly.

In the food waste disposal apparatus 1 according to the present embodiment as described above, the screw blades 31 formed in the screw rod 3 are formed so that the interval between the screw blades 31 gradually decreases toward the discharge hole 42, It is preferable that the garbage is squeezed while being transported.

That is, while the food waste is being conveyed by the screw blades 31 in the direction of the discharge hole 42 side from the charging hole 41, by the interval between the screw blades 31 gradually narrowed, The trash is squeezed to promote dehydration, and the dehydration efficiency is increased.

In the food garbage disposal apparatus 1 according to the present embodiment, a portion of the dewatering pipe 4 located in the discharge hole 42 is formed by a 'fall pipe', whose inner diameter is gradually narrowed toward the discharge hole 42, And is preferably formed in a shape; As a result, the food waste discharged to the outside through the discharge hole 42 is further compressed to promote dehydration, thereby increasing dehydration efficiency.

3 to 5 are views showing a food garbage disposal apparatus according to another embodiment of the present invention. In the food garbage disposal apparatus 1 according to the present embodiment, It is preferable that the screw blades 31 are formed in such a manner that a narrow section that becomes gradually narrower toward the side of the discharge hole 42 in the phase shift charging hole 41 and an extended section that gradually becomes wider are repeated.

That is, the food waste passing through the narrow section is conveyed while being squeezed, and the food waste passing through the extended section is released while being loosened and transferred. Is compressed again through the narrow section of the lane, and the compression and relaxation of the food garbage are repeated in the whole section where the food garbage is conveyed.

Therefore, the dehydration efficiency is maximized by applying the stress due to compression and relaxation to the food waste, respectively.

The crushing means 7 includes a pair of crushing rods 72 connected to the rotating shaft of the crushing motor 71 and formed with crushing blades 73 for crushing food waste on the outer circumference, And arranged in a parallel direction; At the end of the crushing rods 72, connecting gears 74 for gearing with each other may be provided.

That is, when the crushing motor 71 is driven, the pair of crushing rods 72 are rotated by the connecting gears 74 to crush the food waste.

The shredding blades 73 are preferably formed of a ring-shaped protruding ring having a plurality of spaced apart circumferential surfaces on the outer circumferential surface of the shredding rod 72; It is preferable that the inner side surfaces of the hopper 6 disposed in the crushing rods 72 are provided with protruding pieces 75 disposed at intervals between the crushing blades 73.

Accordingly, the food waste is introduced into the dewatering tube 4 via the gap between the shredding blades 73 and the gap between the shredding teeth 73, thereby improving the shredding efficiency.

As described above, the food garbage disposal apparatus according to the present embodiment is simple in structure and advantageous in downsizing, and can be used economically in a small restaurant, thus improving the use efficiency.
