In general, one of the problems caused by the improvement of the living environment and the development of food culture is the disposal of food waste.

Food waste is a waste that contains a lot of salt and water. In the past, it was used as livestock feed, but food waste discharged from large restaurants cannot be used for livestock because paper or toothpicks are rotten in food. Most of these food wastes are landfilled or incinerated after drying.

However, since there is a lot of salt as described above when landfilled not only contaminate the soil but also gives off a bad smell in the process of decomposition, there are a lot of problems, there was a problem that incineration is not made well by moisture during incineration.

Figure 6 is a perspective view of the cap extracted, Figure 6 is a cross-sectional view of Figures 2, 3 and 4 including the first screw, Figure 7 is a perspective view of the first screw extracted in FIG.

As shown in FIGS. 2 to 7, the first housing 20 supports the first screw 30 so as to transport and disintegrate food waste introduced through the hopper 10, and to be crushed. The inlet 21 is formed in the connection with the hopper, the lower portion is a structure in which the outlet 22 for discharging water (sewage) contained in the food waste is formed.

In this case, the inlet 21 of the first housing 20 is eccentrically formed in the rotational direction of the first screw 30 to prevent the food waste from being discharged back by interference by the rotation of the first screw 30. Structure. (Shown in Figure 3)

This structure is to prevent a problem that is accumulated in the inlet (21) is not introduced into the interference by the rotation of the first screw 30 when the food waste is introduced.

The above problem occurs because the distance between the first housing 20 and the first screw 30 supported by the first housing 20 is very narrow, which is caused by the inlet 21 of the first screw 30. When placed on the center, large chunks of food waste are generated by staying at the entrance.

At this time, the rotating first screw 30 is a phenomenon in which a small amount of food waste is transported by winding only a small food waste, and the small food waste rotated together with the first screw 30 is blocked by the food waste staying at the inlet 21. .

Therefore, the inlet 21 is eccentrically positioned in the rotational direction of the first screw 30 so that the food residues can be more easily guided to the inside of the first housing 20.

In addition, the outlet 22 of the first housing 20 has a structure that is located relatively rear than the inlet (21). At this time, the outlet 22 is located in a vertical line with the inlet 21, the overlapping portion is formed with a punching tool (22a).

In addition, when the outlet 22 is made entirely of the other tool 22a, the tool 22a is partially opened to prevent the water from being discharged because the other tool 22a is blocked by food waste. City on 3)

In addition, the second housing 40 communicates with the first housing 20, and functions to grind food waste and guide discharge by grinding with the first screw 30. At this time, the second housing 40 Has a funnel shape due to the shape of the first screw 30.

형상을 취하고 있다.In addition, the inner circumferential surfaces of the first housing 20 and the second housing 40 are formed with at least two steps 23 and 41 which are interconnected to facilitate the transfer of food residues, and the steps 23 and 41 are Staggered

It takes shape.

This structure is to prevent the phenomenon that the food is not transported on the first screw 30 due to the viscosity and moisture of the food waste when the small amount of food waste is introduced.

That is, a small amount of food waste is gathered across the step 23 while rotating together with the first screw 30, and the collected food waste can be smoothly transferred by the wings of the first screw 30.

On the other hand, the first screw 30 is supported by the first housing 20, the end is a structure in which the reducer 70 is connected to limit the number of revolutions.

The first screw 30 has a circular rod shape, and the first transfer blade 31, the compression grinding blade 32, the second transmission blade 33, and the fine grinding blade 34 are sequentially formed, and the compression grinding blade is The bar body formed with (32) is formed to have a larger diameter than the other parts so as to be crimped at the same time as the food waste is crushed.

This structure transfers the food waste introduced into the first housing 20 and the second housing 40 by rotation of the first screw 30-> grinding / compression-> feeding-> fine grinding and This is to discharge through the same process.

At this time, each of the wings 31, 32, 33, 34 of the first screw 30 has a structure in which a plurality of locking grooves 35 are formed along the circumferential surface in order to facilitate the transfer of food waste. The locking groove 35 serves to smoothly transport the food waste accumulated in the step 23 of the first housing 20 and the second housing 40.

And the cap 50 is mounted to the end of the second housing 40 to induce the discharge of food waste by the extrusion of the first screw (30).

On the inner circumferential surface of the cap 50, a plurality of reverse grinding blades 51 are formed radially in contact with the fine grinding blades 34 of the first screw 30 to finely grind food waste.

The food waste discharged through the cap 50 is connected to the drying box 60 and dried, and the drying box 60 will be described with reference to the accompanying drawings.

First, when the crushed food waste is introduced into the tank 62 through the cap 50, the second screw 63 of the tank 62 is rotated forward / reversely so that the food waste is evenly distributed throughout the tank 62. It is dried for a certain time.

At this time, the food waste is dried inside the tank 62 by the blade and the spline 62a of the second screw 63 and simultaneously crushed again.

And the food waste is conveyed while rotating by the second screw 63, at this time, if the spline 62a is not formed on the inner circumferential surface of the tank 62, the food waste is a circle of the second screw 63 It may not move along the major surface.

However, the food waste is piled up over the spline 62a in the tank 62, and the dropping process is repeated, so that the transfer can be made more smoothly.

When the drying process is completed, the second screw 63 is rotated forward to induce food waste to the discharge plate 65. The second screw 63 is disposed by the wing which is in contact with the inner circumferential surface of the tank 62. The food waste is forcibly discharged to the discharge hole 65a of the publication 65.

On the other hand, the second screw (63) has at least one cutter blade (64) formed at an end thereof, while discharging food waste while cutting out the food waste that is dried at the same time.

And the food waste discharged along the discharge hole (65a) of the discharge plate 65 is introduced into the collection box 81 through the opening 83.

At this time, the collection box 81 is configured in the form of a drawer to collect the dried food waste.

On the other hand, the odor flowing into the discharge hole (65a) of the discharge plate 65 is blocked by the sealing member 82 coupled to the front of the discharge plate (65).
