In the plasma generator 60, a plasma is generated (S10), and in the negative ion generator 63, an anion is generated (S15).

In addition, ozone is generated from the ozone generator 66 (S15 '), and the ozone oxidizes and decomposes harmful gases generated during food waste drying, and oxidizes and kills cell membranes of bacteria with strong oxidizing power. In particular, it is mixed with harmful ammonia gas and reduced to water and nitrogen, which is decomposed by anions and plasma.

The interior of the heating chamber 21 in the enclosure 20 by heating the carbon heater 52 is heated (S12) to form a high temperature atmosphere. In addition, by the suction and blowing force of the suction fan 70, the odor gas in the heating chamber 21 is discharged and deodorized (S22) through the distribution duct 72 to the deodorizing filter 80, a part of which is a drying circulation pipe ( 90 is supplied to the discharge gas inlet port 24 (S18) and at the same time the remaining portion is supplied to the heating unit 50 through the heating circulation pipe 92 (S20).

By introducing the through the air inlet duct 62, the load of the deodorizing filter 80 is reduced. In particular, the deodorizing filter 80 is further reduced in the deodorizing load by exhausting in a low density layer at the outlet of the suction fan 70 to improve the service life.

In addition, the hot air is circulated into the basket 40 (S18) and blown around the stirring blade 30 to further accelerate the drying speed of the food waste, and sterilize the food waste by anion and ozone. do.

As described above, the food waste processor 10 of the present invention blows hot air into the basket 40, and the hot air contains negative ions so that both drying and deodorization are performed. In addition, the stirring wing 30, the stirring and pulverization is made at the same time.

In addition, since the odor generated from the food waste is sterilized and decomposed by the carbon heater 52 and the plasma generator 60 and discharged to the filter 80, there is no concern about the occurrence of the odor to the outside. In particular, by recycling a portion of the gas discharged through the drying circulation pipe 90 and the heating circulation pipe furnace 92 can be maximized the drying and deodorizing action.

After the complete drying process of the food waste by the timer 210 is completed, the carbon heater 52 and the plasma generator 60 is stopped, only the suction fan 70 is operated for a predetermined time so that the temperature of the heating chamber 21 is Significantly lower. After that, the door 22 is opened and the basket 40 is taken out. Therefore, the food waste contained in the basket 40 is drastically reduced in volume and is completely dried without smell, and thus can be disposed of as general waste.

Therefore, the sterilization and deodorization device of the food waste disposal system of the present invention is excellent in the sterilization and deodorization process of meat or fish wastes, as well as the processing of general food wastes, in particular.
