Description

Food waste handler with a condenser.

The present invention relates to a food waste disposal device having a condenser, and more particularly, to a food waste disposal device configured to discharge steam and gas generated by stirring, reducing evaporation and fermentation of food waste, wherein the condenser in the exhaust duct It provides a food waste disposal device having a condenser that improves the deodorizing power of the deodorizer, the lifespan is extended, the ozone generation efficiency is increased, and the water is not controlled.

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 nearby drinking water sources or air. .

In the example food waste processor of FIG. 1, an input door 12 for injecting the residue and a discharge door 21 for removing the waste after treatment are formed outside the main body of the food waste processor made of a heat insulator. The main body is provided with a fermentation tank 11 for processing the residue and an exhaust duct 30 for discharging the fermentation gas and water vapor generated during the residue treatment process to the outside, and the exhaust duct 30 has a bad smell of the fermentation gas. Deodorizer 31 and the like for removing the is installed. The fermentation tank 11 is detachably installed in the main body so as to be detachable when the residue is removed or configured to remove the residue through the opening / closing door 22.

In addition, inside the fermentation tank 11, a stirrer 16 is rotatably mounted to decompose and treat the residue by stirring and fermenting the fermenter and the residue introduced from the outside. The stirrer 16 is rotated in the forward and reverse direction by receiving a driving force by the electric mechanism 13, such as 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 'is introduced through the input door 12 in the fermentation tank 11, and the fermentation produced by stirring, reducing water evaporation, and reducing fermentation of food waste. The gas and the water vapor are discharged through the deodorizer 31 provided in the exhaust duct 30.

At this time, the fermentation gas and water vapor at a high temperature of 50 ~ 60 ℃, ammonia (NH ₃ ) component contains a large amount of odor, the water vapor contains a large amount of water is discharged by the fermentation gas and water vapor to the deodorizer (31) After passing through), the odor and the like are deodorized, and then can be discharged 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 fermentation tank 11. The internal temperature and humidity conditions also control the operation of the food waste handler. One example of the control system is shown in FIG.

After the food waste is put in FIG. 2, the current temperature value and the humidity value are changed from the temperature sensor 17 and the humidity sensor 18 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 controlled, and the stirrer 16 is intermittently forward and reverse rotated to maintain optimum fermentation or decomposition conditions of the food waste.

However, according to the exhaust structure of the food waste processor of the above-described configuration, steam and gas generated while the food waste is stirred, reduced evaporation, and fermentation in the fermentation tank 11 are exhausted through the exhaust fan 19 '. While passing through the duct 30, the odor is deodorized while being in contact with the deodorizer 31, and then discharged to the outside, while the water vapor contains a large amount of water, while passing through the deodorizer 31 Moisture is adsorbed on activated carbon used to reduce the deodorization efficiency, shorten the life of the deodorizing device, and also lowers the ozone generation efficiency.

In addition, by evaporating the water inside the fermentation tank 11 through the water vapor, a problem such as the user to arbitrarily input water into the fermentation tank 11 to control the water in the fermentation tank 11 has been derived.

Therefore, the present invention is designed to solve the above problems, by installing a condenser in the open duct to remove moisture from the water vapor, and then configured to pass through the deodorizer, thereby improving the deodorizing power and life of the deodorizer, It is an object of the present invention to provide a food waste disposal apparatus having a condenser that has an effect of increasing ozone generating efficiency and not controlling moisture inside the fermentation tank.
