Referring to the operation of the embodiment of the present invention made in this way in detail as follows.

The user inputs food waste into the hopper 5 of the food crusher 1. At the same time, water is supplied to the water inlet 7 of the food shredder 1 using a hose or the like.

Food waste and water supplied to the hopper 5 are mixed with each other and introduced into the crushing container 9.

When the driving source 13 is driven, the crush plate 11 rotates. The shredding plate 11 is finely shredded food waste because the blade or the shredding block is radially coupled.

Therefore, the food waste is crushed in the form of water, so it becomes a form of porridge. And the conveying fan 12 pushes the food waste of the state like porridge to the discharge pipe 15 by the rotating force.

Then, food waste in the form of porridge flows into the pressing container 19. At this time, when the driving source 23 of the food compressor 3 rotates, a driving force is transmitted to the compression screw 21, and the compression screw 21 also rotates.

When the compression screw 21 rotates, the rotary blade 35 provided on the compression screw 21 rotates to push the food waste upwards (see FIG. 3). The food waste is compressed between the rotary blade 35 and the pressing cylinder 19 while the water is discharged to the outside through the perforations provided in the pressing cylinder 19.

And the food waste continues to push upward while passing through the food discharge hole (25a) of the fixed plate 25 to press the pressing plate (27).

At this time, the pressing plate 27 is moved upward while being guided by the fastening member 29 or the guide shaft 39 (shown in FIG. 4).

In this case, the pressing plate 27 can move upward uniformly as a whole without inclining to one side.

An example of this embodiment of the present invention serves to prevent breakage of the press plate 27 and to increase the dewatering efficiency.

The food waste is then discharged to the discharge guide 41 between the stationary plate 25 and the pressing plate 27.

The food waste discharged through the discharge guide 41 is stored in the discharge container B installed at the end of the discharge guide 41. Therefore, the dehydrated food waste can be discharged to the outside.

Food waste that has undergone this treatment can be significantly reduced in amount, thereby reducing the cost of discharging food waste.

Since the second guide member 41b of the discharge guide 41 is hinged to the first guide member 41a, a discharge container B higher than the second guide member 41b may also be used.

As such, when the weight reduction operation of the food waste is completed, the user may clean the pressing tube 19 by using the injection nozzle 43. That is, the water sprayed from the injection nozzle 43, as well as the outside of the pressing cylinder 19, as well as a portion of the water inlet into the inside of the pressing cylinder 19 through a plurality of perforations provided in the pressing cylinder 19 ( 19) and the inside of the case 17 can be cleaned.

On the other hand, the rotary blade 35 of the compression screw 21 is rotated along with the brush 37 while rotating. As the brush 37 rotates, the perforated part provided in the crimping cylinder 19 is perforated and the perforated part of the crimping cylinder 19 can be prevented from being blocked. Therefore, the dewatering efficiency of the food waste can be further increased.

The brush 37 can prevent the blade 35 from being bent or damaged in the opposite direction when the rotary blade 35 moves in a forward direction (FIG. 10 arrow direction) while rotating. That is, the rotary blade 35 protruding portion 35a protects the brush 37 from being damaged, thereby increasing dewatering efficiency and increasing durability.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And it goes without saying that the invention belongs to the scope of the invention.
