The present invention crushes the food waste by a pair of rotating helical gears by rotating the food waste with microwaves as a heat source and transported to the injection chamber, and continuously to the drying chamber through the injection tube and nozzle at a constant pressure It is a device for moving and drying along the screw curve of a drying screw, and the steam generated during drying relates to a screw-type food waste treatment apparatus using a microwave which is purged by a deodorization tower so that no odor is generated.

Food waste is increasing year by year, and due to the difficulty of disposal due to landfilling or incineration, food waste emission standards are being strengthened gradually.

The biggest problem with food waste is that it contains a large amount of moisture, which easily rots and generates odors and sewage.

Simply embedding food waste underground causes environmental pollution, including leachate, and may be an inappropriate method for long-term treatment due to limited land area.

Food waste can be used as livestock feed when processed by removing debris, or it is highly valuable as compost.

In order to effectively treat food waste, water must be removed, and there are a number of conventional technologies developed for this purpose.

 Hereinafter, a representative prior art will be described.

First, a technology related to the treatment method of household food waste of the Republic of Korea Patent Application No. 1997-0013624 has been known, this technology is finely pulverized the food waste generated at home in the grinding chamber (2) injection hopper (3) Injecting into the processing chamber (4) through the transfer conveyor (5) in the processing chamber in the microwave microwave generated from the microwave generator 7 is irradiated to the food waste to dry and sterilize by dielectric heating method The present invention relates to a method of treating household food waste in which steam is discharged to a batch device and the treated food waste is recycled.

Patent Application No. 10-2005-0417) When discharging food waste from the grinding hopper with the grinding blade and then discharging the food waste to the outlet of the bottom, food waste with a lot of fiber is not crushed and is not crushed on the grinding blade and is not discharged. In addition, while providing an unnecessary load to the motor, there is a problem of the clean state inside the hopper.

In order to solve the problems of the prior art and to provide a processing apparatus capable of more efficiently treating food waste, the present invention uses a pair of interlocking helical gears to crush food waste and is driven by the rotational force and lead angle of the helical gear. The food waste pulverized at the obtained pressure was transferred to the injection chamber through the injection tube and the nozzle to be supplied continuously to the drying chamber composed of the porous cylinder and the drying screw.

The microwave generated by the microwaves uniformly passes through the electromagnetic wave uniform dispersion device 240 in the waveguide 230 toward the drying screw 200 and the porous cylinder 210, and the microwaves again face the drying screw and the porous cylinder. Reflecting reflectors to make By using the resonator plate 260 to be well exposed to food waste, water vapor generated during the drying process passes through a plurality of micro-pores and suction broa (300) formed at the end of the porous cylinder 210 generally known Various filtration filters (charcoal, activated carbon, etc.) of the sequential deodorization tower 320 is forced to be discharged to the atmosphere in the state of significantly reduced odor after the filtration process, drying screw 200 and the porous cylinder The food waste dried over was crushed again by the low speed grinding blade 190 installed at the end of the low speed motor 180 which is moved by a separate power, and collected by the collection box 290 through the outlet 280.
