5 is a plan view, a bottom view and a cross-sectional view of the fixing plate of the food waste dehydration device according to an embodiment of the present invention.

2, 3 and 5, in another embodiment of the present invention, the fixing plate 60 is further provided, the fixing plate 60 is in close contact between the bottom of the housing 70 and the bottom of the drum 40 Fixed and extruding waste which is the rotational side of the residue extrusion hole 61 and the rotating plate 50 having the same radius as the residue compression hole 52 of the rotary plate 50 and communicating with the residue discharge hole 78 of the housing 70. The cutting blade 62 is formed on one side of the ball 61. As the rotary plate 50 rotates, the cutting blade 55 of the rotary plate 50 and the cutting blade 62 of the fixed plate 60 are closely intersected, and the food waste is cut and discharged.

In addition, in another embodiment of the present invention, as shown in Figures 2, 3 and 5, the fixed plate 60 is the rotational direction of the rotary plate 50 in the same radius as the residue compression hole 52 of the rotary plate 50 Compression inclined surface 63 inclined to the other side of the residue extruded hole 61 on the opposite side and the residue discharge hole 78 of the housing 70 under the fixed plate 60 from the cutting blade 62 inside the residue extruded hole 61. ) May be provided with an inclined discharge inclined surface 65 so that the cutting blade 62 forms an acute angle up to a portion in communication with the. The outer surface of the fixing plate 60 is connected with the cutting blade 62, the compression inclined surface 63 is gradually lowered is connected to the residue extruded hole 61 and the back of the residue extruded hole 61 can easily escape the residue The discharge inclined surface 65 is formed. Compression-degradation surface 63 is compressed and dehydrated debris pushed out through the residue compression hole 52 of the rotary plate 50 is stacked, as shown in Figures 2 and 5, in the compression inclined surface 63, the outer surface of the rotary plate ( Since the inner and outer circular protrusions 53 and 54 of 50 are wrapped and turned, the compressed dewatered debris accumulated on the compression inclined surface 63 is quickly and strongly pushed toward the waste extruded hole 61.

The operation of the food waste dehydration reduction apparatus according to the present invention configured as described above will be described with reference to FIGS. 2 to 6.

When the food waste soaked with water is introduced into the hopper 10, the guide ring 91 installed on the top of the screw fixing bolt 90 rotates together with the compression screw 30, and the food waste is introduced along the input slope surface 11. ) To guide the flow.

Food waste introduced into the inlet 14 is pressed along the bottom of the inclined surface 11 by the rotation of the compression screw 30 is pushed into the drum (40). The food waste generated in this process is cut by the intersection of the inclined bottom blade 13 and the compression screw 30 upper surface 31. The food wastes pushed into the drum 40 are compressed by being pressed down by the wall blade 43 on the wall of the drum 40 and the spiral blade 33 of the compression screw 30.

In the initial state of the food waste dehydration reducing device, that is, in the state that the compressed dewatered debris is not filled to a predetermined density or the like in the residue compression hole 52, the residue extrusion hole 61, the residue discharge hole 78, etc. When it is put in the empty space for the first time, half of the water generated during the process of compressing and transporting food waste downward flows down and is discharged to the waste outlet (75), but it is a waste compression hole (52) and waste extruder. 61, the residue discharge hole 78 is filled with the compressed residue by the elasticity of the discharge packing 77, which is one of the opening and closing means 77, the seal is made when the density is more than a certain density, so that more moisture toward the waste outlet 75 You will not leak anymore. The density or degree of compression of the compression dregs forming the discharge passage will be determined by the elastic strength of the waste packing 77 and the properties of the food dregs.

If the food waste is continuously introduced while the discharge passage is filled with the compressed waste, the discharge passage is formed by the compression force between the rotation of the screw 30 and the extrusion force between the fixed plate 60 by the rotation of the rotating plate 50. Forced to move the compressed debris tight tightly to the discharge packing (77) to be discharged, but when the input is stopped, the compressed and dehydrated debris is very tight in the discharge passage is clogged is a thorough sealing function.

When the food waste is injected while the discharge passage (compression hole, extrusion hole, discharge hole) (52, 61, 78) is sealed, the water generated during the feeding and compression process will seep upward and the seepage moisture will flow through the strainer (20). Naturally drained through the micro-pores 22 of the flow through the space between the drum 40 and the housing 70 is discharged to the drain hole (74).

At this time, the rotation of the compression screw 30 should be 50 rpm or less at low speed so that the solids in the water can be effectively compressed while quietly sinking down.

If the compression screw 30 is rotated at a high speed, the solid waste is decomposed and thus is not compressed or discharged.

The dehydrated debris while being pushed to the lower end of the compression screw 30 is compressed and filled in the debris compression hole 52 of the rotating plate 50 in close contact with the bottom surface of the compression screw 30.

The compressed debris filled on the compression inclined surface 63 of the fixed plate 60 is extruded along the inclined surface by the inner and outer circular protrusions 53 and 54 of the rotating plate 50 which wraps around the outer surface of the inclined inclined surface 63. It is quickly sent to 61. The cutting blade 55 of the rotating plate 50 and the cutting blade 62 of the fixing plate closely contact each other in the process of flowing from the residue compression hole 52 of the rotating plate 50 to the residue extrusion hole 61 of the fixing plate 60. The chips are finely cut so that they are extruded quickly without being caught when discharged.

If the debris is not extruded quickly and is delayed inside, it will be crushed slowly and become like porridge. In addition, the discharge packing 77 prevents the residual moisture of the residue generated in the process of cutting and extruding the residue by the rotating plate 50 and the fixing plate 60 to flow toward the residue outlet 75 and the driving means 80. For example, since the waterproof lida 79 blocks the low-speed motor 80 or the motor 80 provided with the reduction gear, the water discharge leads to the drain 74 through the pressure drain 76.

In addition, since there is no compression dehydration network structure at the compression part, even if hard foreign matters are injected incorrectly, there is no failure to tear the net, and the foreign materials that are wrongly added can be easily removed by the reverse rotation operation of the compression screw 30.

And because it is equipped with a brush that sweeps the outer wall of the rotating mesh, even if used for a long time, the fine pores of the mesh are not blocked and drainage is good.

In addition, when replacing the wearable parts mounted inside the housing, it is not necessary to remove the housing from the sink, so the parts can be easily replaced without dripping water. If the odor occurs due to accumulated time inside the housing after long use, it is convenient and hygienic because the inside can be cleaned by removing the input hopper alone.

In the above, the present invention has been described in detail with reference to the accompanying drawings and embodiments, the accompanying drawings and the above embodiments are described by way of example to help those of ordinary skill in the art to understand the present invention. As such, the scope of the invention should be construed according to the invention set forth in the appended claims, which includes various modifications, alternatives, and equivalents by one of ordinary skill in the art.

The present invention relates to a food waste dehydration reducing apparatus, and dehydration of food waste using the dehydration reducing apparatus of the present invention can easily separate foreign matters that are not food, and the salinity in the food decreases the absolute salt with dehydration. As it lowers, the mixing of foreign substances and high salt concentration, which have been the obstacles of food waste recycling, can be eliminated, so that recycling such as composting or feed can be used, and thus can be very useful in the field of food waste processing.
