Description

Food waste processor with long ozone reaction path

The present invention relates to a food waste processor having a long ozone reaction path, and more particularly, a long ozone reaction path for reacting and deodorizing the exhaust gas generated by stirring, fermenting and decomposing food waste with ozone in an efficient and durable manner. Food waste disposer.

In general, each home or restaurant, such as the leftover (food waste) is discharged every day, such residues are used as livestock feed or simply filtered through a strainer and then discarded. These residue treatment methods increase the amount of food waste in the total amount of waste, and if the food waste is not disposed of smoothly, it causes odors and pollutes the surrounding drinking water or air. .

In the example food waste processor shown in Figure 1, the main body 10 of the food waste processor made of a heat insulating material is formed with an input door 12 for inputting the residue and a discharge door 21 for removing the residue after treatment The inside of the main body 10 is provided with a fermentation tank 11 for processing residue and a deodorizer 30 for removing odor generated during the residue treatment process. The fermentation tank 11 is detachably installed in the main body so as to be detachable when removing the debris, or as shown to remove debris through the opening and closing door 22.

Moreover, inside the fermentation tank 11, the stirrer 16 is rotatably mounted, and the residue is decomposed and processed by stirring and fermenting the fermentation agent and the residue added from the outside. The stirrer 16 is rotated forward and backward by receiving a driving force by the electric mechanism 13 by a chain, a timing belt, etc. which are provided in the fermentation tank 11, and the motor 14, such as an AC induction system.

Meanwhile, a suction fan 19 and an exhaust fan 19 ′ are installed at the upper portion of the food waste processor, and the suction fan 19 and the heater 15 installed therein are provided by a kind of fan heater function. If necessary, the outside air is heated and introduced, and the exhaust fan 19 ′ deodorizes the gas (including water vapor) generated therein through the deodorizer 30 installed in the exhaust duct 19 and discharges it to the outside.

The motor 14, the heater 15, the suction fan 19, the exhaust fan 19 ′ and the like are connected to the control panel 20 using a microcomputer, so that the operation of the food waste disposal system is controlled by a predetermined procedure or program. It may be configured to be controlled. The control panel 20 also controls the operation of the food waste processor in a sequential or manual operation according to the set operation mode, and receives the input of the temperature sensor 17 and the humidity sensor 18 installed inside the drying vessel. The internal temperature and humidity conditions also control the operation of the food waste processor. One example of the control system is shown in FIG.

After the food waste is put in FIG. 2, the current temperature and humidity values from the temperature sensor 17 and the humidity sensor 18 are changed from the time when the input door 12 is closed by the input door sensor 12 ′. When input to the microcomputer 20a via the A / D converters 20b and 20c, the heater 15, the motor 14, the suction fan 19 and the exhaust fan are passed through the driving units 20d and 20e according to a predetermined program. By driving (19 '), the temperature and humidity are adjusted to 20 to 30 DEG C and 40 to 60%, and the stirrer 16 is intermittently forward and reverse rotated to maintain optimum fermentation or decomposition conditions of food waste.

However, the deodorizing device 30 of the food waste treatment device having the above-described structure, although it is forced stirring and fermentation, improves the efficiency of fermentation and shortens the processing time. However, the odor of the mixed gas of the gas and water vapor generated during stirring is usually reduced. It is difficult to remove only by the activated carbon deodorizing filter 34, and a method of increasing the deodorizing effect by using the ozone generating lamp 32 as shown in FIG. 1 has been applied. In this case, a high voltage from the high pressure generator 31 is applied to the ozone generating lamp 32 to generate ozone, and the ozone generated from the lamp 32 reacts with the exhaust gas flowing from the lower portion to increase the deodorizing effect, but for a long time In use, there is a problem that the exhaust gas containing water vapor directly contacts the ozone generating lamp 32, and foreign matter adheres to form a scale, thereby degrading the efficiency and deodorizing effect of the ozone generating lamp, and the waste ozone downstream. Although the waste ozone is prevented by passing through the adsorption filter 33 to adsorb the waste ozone, in consideration of deterioration of the ozone generating lamp 32, when the high performance is achieved, there is a problem that the air leakage of the waste ozone is likely to occur. .

In addition, in FIG. 1, the flow rate at which the exhaust gas and the waste ozone pass through the waste ozone adsorption filter 33 and the deodorization filter 34 of the deodorizing sheet 30 is provided adjacent to the ozone generating lamp 32 and below. Since the inlet of the exhaust gas is formed, it is not uniform in the cross section, the upper part is high and the lower part is low, so that the effective deodorizing effect is not obtained, and the lifespan of the filters is shortened. This is particularly acute when the ozone wall is formed.

The present invention is to solve the above problems, the non-contact type ozone generator and long ozone reaction path to the deodorization by reacting the ozone generated by stirring, fermentation and decomposition of food waste with ozone efficiently and durable. The object of the present invention is to provide a food waste processor, and furthermore, to provide a food waste processor that can reduce noise caused by the discharge of exhaust gas and can prevent waste ozone from leaking out.
