In the state in which the door 22 is opened as shown in FIG. 2, the food waste is contained in the basket 40 and accommodated in the housing 20. At this time, the stirring blade 30 inserted into the connection port 41 of the basket 40 is inserted and coupled to the rotary shaft 102 of the stirring motor 100.

When power is applied through the control unit 200 in this state, the carbon heater 52, the plasma generator 60, the negative ion generator 63, the ozone generator 66, the suction fan 70 and the stirring motor 100 are operated. do. 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 gas 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, various odorous gases in the heating chamber 21 are discharged and deodorized (S22) to the deodorizing filter 80 through the distribution duct 72 by suction and blowing power of the suction fan 70, and a part thereof is for drying. S18 is supplied to the discharge gas inlet port 24 through the circulation pipe 90 and at the same time, the remaining part is supplied to the heating part 50 through the heating circulation pipe 92.

At this time, the negative pressure is generated in the heating chamber 21 by the amount of exhaust discharged through the deodorizing filter 80, and the outside air is introduced into the heating chamber 21 through the outside air inlet duct 62.

The negative ions generated in the negative ion generator 63 (S15) are supplied to the deodorizing filter 80 by the suction fan 70 together with the fresh external air introduced through the duct 69. Therefore, the catalyst reaction of the deodorizing filter 80 proceeds smoothly to increase the deodorizing effect, thereby extending the life of the deodorizing filter 80 is economical.

At this time, if a negative pressure difference is set at a ratio of 80%: 20% of the amount of plasma flowing from the plasma generator 60 and the amount of anions generated from the anion generator 63 as much as the amount of air going out of the deodorizing filter 80, the deodorizing filter 80 Anion is released to the air through the) can be obtained.

In particular, plasma, ozone, and anion become one of the three to decompose harmful gas, and the air coming out through the deodorizing filter 80 refreshes a person's mood with fresh air.

In this state, the stirring blade 30 is rotated to stir and crush the food waste contained in the basket 40 (S14). At this time, the hot air, anion and ozone introduced into the in-port 24 are injected through the exhaust hole 32a and blown into between the food wastes stirred in the basket 40.

Therefore, the food waste contained in the basket 40 is rapidly dried by stirring, crushing and hot air, and sterilization of the food waste bacteria by anion and ozone. At this time, the food waste coming up on the inner wall of the basket 40 is restrained by the unevenness 43.

At this time, the moisture generated from the food waste is not connected to the discharge gas inlet port 24 because the connection port 41 protrudes to a certain height from the bottom surface of the basket 40.

On the other hand, various compounds generated from the food waste subjected to hot air drying in the basket 40 are decomposed by the plasma generated through the plasma generator 60. That is, compounds such as sulfurous acid gas, nitrogen compounds, carbon monoxide, etc. generated from food waste are decomposed to remove odors.

That is, when the plasma generator 60 applies a negative boltage to a pointed needle, the energy such that electrons with negative electrons from the tip of the needle may cause ionization by a high energy process. It is released at high speed and collides with molecules and compounds in the air in the heating chamber 21 to form anions, thereby decomposing odors by decomposing dust, various harmful gases and compounds in the heating chamber 21.

Therefore, as the drying time elapses, the gas from which the odor is removed is sucked into the suction port of the suction fan 70.

On the other hand, a part of the gas sucked by the suction fan 70 (S16) is supplied to the injection nozzle 58 through the heating circulation pipe (92) (S20), various exhaust gases passing through the injection nozzle 58 and The compound is sterilized and deodorized by far infrared rays while passing through the carbon heater 52.

Therefore, in the heating chamber 21, various compounds generated in the basket 40 are decomposed and deodorized by the plasma unit 60 and the carbon heater 52, and the fresh air is discharged through the filter 80 by the amount of the fresh air. 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.

On the other hand, according to the present invention, when the drying process of the food waste is completely completed by the control unit 200, the control unit 200 may notify the user by visual or / and audio signals through the alarm unit 214 (for example, an alarm lamp or a speaker).

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 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 completely dried without smell, so that it can be disposed of as general waste.

Therefore, the food waste processor 10 of the present invention is excellent in processing not only general food waste but also particularly odorous meat or fish waste.
