Hereinafter, the operation of the large-capacity food waste processor having a odor removing function according to an embodiment of the present invention.

Looking at the drying process of the food waste using a large-scale food waste processor with a odor removing function according to the present embodiment, first open the door 21 of the hopper 20 in the state in which the pulverizer 30 is operated and food waste When it is added, the crusher 30 is crushed to a size easy to dry and falls to the trash drying network 42.

In this way, when a certain amount of food waste is put in and the door is closed, the stirring operation by the stirrer 50 is performed. At this time, the water is sprayed and washed to the waste drying network 42 through the waste washing water supply unit 141 according to the state or type of food waste introduced. When the water injection process is performed in this way, it is possible to improve the treatment efficiency during the treatment of food waste containing liquid foreign matter having a high viscosity. In addition, when the injection process of water is carried out, the discharge control valve 81 of the exhaust line 80 is opened so that the washing water is discharged to the outside.

Then, when the external air is supplied to the heated heating means 60 by the hot air blowing fan 70, the external air is converted into hot air by a heat exchange action and sprayed onto the trash drying network 42 to perform the drying process of food waste. do. At this time, the forward and reverse rotation operations are repeatedly performed by the stirrer 50 to agitate the food waste, so that the drying process is more effectively performed.

In this drying process, since fine foreign matter is removed from the inlet hole 42a of the waste drying net 42 and attached to the inner wall surface of the drying furnace body 41, the water control valve 142a of the wall washing water supply unit 142 at a predetermined time. The inner wall surface is washed by the washing water sprayed through the injection hole of the water spray member 142b by opening the).

On the other hand, the dry air containing moisture evaporated from the food waste in the drying process is introduced into the sealed container 111 through the exhaust line 80 and the odor inlet pipe 112 by the suction force of the dry air suction fan 120. After that, the moisture remains in the water inside the sealed chamber 111b, and the dry air containing the odor is discharged to the odor removing means 130 through the odor discharge pipe 113.

When the dry air flows into the odor removing means 130 as described above, the odor is removed and extinguished because the exposed air is exposed to the heating element 132 while moving along the curved flow path of the odor removing chamber 131 formed by the partition 131a. That is, since it is thermally decomposed by an ultra-high temperature heating element made of molybdenum silicide (MoSi ₂ ) material heated to more than 1,500 ° C and exposed to near infrared rays emitted from the heating element, the odor component is removed and only clean dry air is discharged through the exhaust pipe. At this time, the near-infrared radiation emitted from the heating element 132 neutralizes the cation of the substance which is the main culprit of the odor by light rays having the property of anionizing the air, thereby removing the odor.

In addition, although heat is generated in the heat exchange duct 133 and the low voltage transformer 160 where the power supply unit 132a side of the heat generator is positioned, the hot air blower connected to the heat exchange duct 133 side generates heat. Since the outside air passes through the through hole 161 of the low voltage transformer 160 and the internal space of the heat exchange duct 133 by the action of the fan 70, a stable operation can be performed even if a separate cooling device is not provided. . In addition, as the outside air heated by the waste heat is supplied into the drying furnace 40 while passing through the heat exchange duct 133, hot air can be sprayed onto the food waste, thereby reducing the drying time of the food waste. And energy efficiency can be improved.

The control unit detects the moisture content by the detection signal applied from the humidity sensor 90 in the process of drying the above-mentioned food waste and is less than the preset value compared with the preset moisture content, the rotation direction of the stirrer 50. Rotate in the discharge direction of the food waste and at the same time to drive the door device 43 to discharge the dried food waste. That is, when the door driving means 43c is driven, the discharge door 43b is moved toward the waste discharge port 43a, so that the through portion 43d of the discharge door 43b is in communication with the waste discharge port 43a. The dried food waste in the vista 42 is discharged to the outside by the action of discharging the stirring member 52.

The discharge control valve 81 is installed to the exhaust line 80 inclined in the discharge direction, and is composed of an opening and closing pad formed of a pad of a material having a predetermined elasticity and flexibility, such as rubber and urethane. When the discharge control valve 81 having such a structure is installed, the gas component of the atmospheric pressure level discharged from the inside of the drying furnace 40 is blocked by the opening / closing pad and circulated to the drying furnace side by the suction force of the hot air blowing fan 70 and dried. The liquid substance discharged from the inside of the furnace 40 is discharged to the outside while pushing the opening and closing pad by water pressure.

Since the operation of the large-scale food waste processor with odor removing function according to another embodiment of the present invention is similar to the embodiment, only a part having a difference will be briefly described.

The food waste introduced via the hopper 20 and the pulverizer 30 is dried by hot air supplied by the heating means 60 and the hot air blowing fan 70 together with the stirring action of the stirrer 50. After the dry air generated in the process flows into the odor removing chamber 210 through the connecting pipe 215, the odor is removed.

That is, while the pyrolyzed pyrolyzed by an ultra-high temperature heating element made of molybdenum disulfide (MoSi ₂ ) made of molybdenum disulfide (MoSi ₂ ), which moves for a relatively long time along the curved flow path of the malodor removing chamber 211 formed by the partition wall 211a, is heated. Since it is exposed to near-infrared rays emitted from the odor component, only the clean dry air is discharged to the outlet side.

In the heat generation process of the heating element 220, the outside air is introduced into the cooling duct 212 where the power supply unit 221 is located by the cooling fan 213 to perform the cooling operation of the power supply unit 221. The heating element 220 performs a stable heating action.

Then, the air discharged through the outlet of the odor removal chamber 211 and the cooling duct 212 is joined to the exhaust line 80 via the air exhaust line 216, and then discharged to the outside.
