As shown in FIGS. 3 and 4, the first and second pulverizing members 22 and 23 have first and second pulverizing members 22 and 23, which have opposite ends and are rotatably fixed to the front and rear surfaces of the chamber 21, Shafts 22a and 23a and a plurality of first and second crushing blades 22b and 23b extending along the longitudinal direction of the first and second crushing shafts 22a and 23a.

The first and second grinding bodies 22 and 23 are disposed in parallel to the inside of the chamber 21, and the first and second grinding blades 22b and 23b are disposed in a mutually offset state, Do not.

As shown in FIG. 4, the first and second crushing shafts 22a and 23a are coupled to each other in a tooth-like manner, and the first and second crushing shafts 22a and 23a Is connected to the drive unit 26 by a power transmission means 27 such as a chain, a belt, or the like. It is to be understood that such connection may be made in various forms known as shown in FIG.

When the chamber 21 is viewed from the front, the first and second grinding bodies 22 and 23 are rotated in the inner direction (normal rotation direction) adjacent to each other in accordance with the driving of the driving unit 26.

The food waste located on both sides of the chamber 21 by the rotation is crushed while being transferred between the first and second crushing bodies 22 and 23.

The first and second pulverizing bodies 22 and 23 are configured to rotate reversely, and when the object such as metal waste, which is difficult to be pulverized, is input, the first and second pulverizing bodies 22 and 23 can be recovered in a reverse rotation manner.

The crushing unit 30 has both ends and extends in the direction of both ends of the crushing unit 20. The crushing unit 30 has an inlet 32 through which the food waste is crushed and a discharge port 33 through which the crushed food waste flows. A screw conveyor 34 rotatably fixed to both ends of the compression tube 31 and a driving motor 35 for transmitting a rotational force to the screw conveyor 34. [

When the food garbage disposing device 1 is viewed from the front, one end is positioned below the crushing unit 20, and the other end is positioned in one direction Thereby forming an elongated shape.

The inlet (32) is provided at the lower end of the one end, and the outlet (33) is provided at the upper end of the other end. That is, the food garbage disposal apparatus 1 is configured such that the inlet port 32 and the discharge port 33 are spaced farthest from each other in the longitudinal direction of the compression pipe 31, and the compression of the food waste is maximized .

The screw conveyor 34 has a shaft 36 having both ends and extending in both ends thereof and a screw 37 provided along the longitudinal direction of the shaft 36.

Both ends of the shaft 36 are rotatably fixed to both ends of the compression tube 31, and one end of the shaft 36 is connected to the driving motor 35. It is needless to say that the connection between the driving motor 35 and the shaft 36 may take various forms as shown in FIG.

At this time, it is preferable that the crimping portion 30 further includes a support frame 38 for supporting the compression tube 31 upwardly inclined from the one end to the bullet end.

The support frame 38 may be composed of a plurality of frames and is fixed to the frame unit 40 or another separate structure 100 or the like to support the compression tube 31 in an inclined manner.

The compression tube 31 is upwardly inclined in a direction in which the food waste is moved so that moisture that is compressed and discharged by driving the screw conveyor 34 is separated and discharged in a direction opposite to the moving direction of the food waste .

The compression unit 30 may further include a discharge pipe 39 for collecting or discharging moisture generated in the process of pressing the food waste to the lower side of the one end of the compression pipe 31. It is needless to say that the discharge pipe 39 may be provided with an opening / closing valve 39a.

The moisture discharged through the discharge pipe 39 is heated to a temperature of about 90 degrees by the drying unit 50 described later, so that food poisoning bacteria and infectious germs can be discharged in a sterilized state.

The food waste disposal apparatus 1 may further include a drying unit 50 for drying the food waste introduced into the inlet 32 and transferred to the outlet 33.

The drying unit 50 may include a plurality of magnetrons 51 that receive power from the outside and radiate a microwave into the inside of the compression tube 31.

The plurality of magnetrons 51 uniformly heat the outside and inside of the food garbage by direct heating heating the water molecules capable of dielectric heating by generating a microwave, that is, a power wave of 2,450 MHz. In other words, the plurality of magnetrons 51 radiate a microwave to the inside of the compression tube 31 and heat-dry the food garbage moving inside the compression tube.

The plurality of magnetrons 51 are installed along the longitudinal direction of the compression tube 31 and a plurality of hollows 31a are formed in the compression tube 31 so that the plurality of magnetrons 51 can be fixedly installed. .

Preferably, the front ends of the plurality of magnetrons 51 are introduced into the plurality of hollows 31a, and the microwaves are hermetically sealed to prevent the microwaves from flowing out to the outside.

In the food garbage disposal apparatus 1, a carbon-containing material (not shown) containing a carbon component may be applied or attached to the inner circumferential surface of the compression pipe 31 to increase the heating effect. This makes it possible to reduce the waste of heat.

The food waste is dried by the microwave and high-temperature steam is generated. In this high-temperature steam, heat is recovered by a separate heat recovery device (not shown), and the moisture is sterilized by high temperature sterilization.

The food waste is firstly dewatered in the crushing process in the crushing unit 20 and is dehydrated in the process of being squeezed by the crushing unit 30 and is simultaneously dewatered by the microwaves generated in the plurality of magnetrons 51 And finally dried.

That is, the plurality of magnetrons 51 are supplied with power from the outside to generate a microwave, and the food garbage is finally heated and dried by the microwave.

Therefore, the food garbage disposal apparatus 1 grinds the food garbage supplied from the outside, while the food garbage to be crushed is compressed and dried by microwave to minimize the moisture content, There is an effect that the amount can be reduced.

The dehydrated waste becomes flammable waste, and the amount of waste discharged is measured by RFID.

Compared with the conventional Ni-Cr heating method, the microwave heating method according to the present invention takes about 20 minutes to dry food waste using a 20 Kw magnetron, and takes about 240 minutes to dry a 20 Kw electric heater In general, the microwave heating method according to the present invention requires about 1/5 of energy compared with the conventional heating method.

Since the moisture content of the food waste is about 80%, the final waste amount of the food waste treated by the present invention is reduced to about 1/10 of the initial input weight.

The present invention is not limited to the above-described embodiments, but may be modified in various ways within the spirit and scope of the present invention as set forth in the following claims. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
