Description

Food waste disposer with dormant liquid spray means of deodorizing and fermenting agent

The present invention relates to a food waste treatment device having a dormant liquid spray means of deodorizing and fermenting agent, and more particularly, in a food waste disposal device having a structure capable of stirring, reducing evaporation and fermentation of food waste, The present invention relates to a food waste processor having a deodorization and fermentation agent spray means for preventing deterioration of fermentation conditions due to low humidity or low humidity.

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 of the food waste processor shown in FIG. 1, an input door 12 for injecting the residue and a discharge door 21 for removing the waste after treatment are formed on the outside of the main body of the food waste processor made of a heat insulator. Inside the main body, a fermentation tank 11 for processing residue and a deodorizer (not shown) for removing odor generated during the residue treatment process are 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.

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 in the forward and reverse direction by receiving a driving force by the electric mechanism 13, such as a chain, a timing belt, etc. provided in the fermentation tank 11, and the motor 14, such as an AC induction system.

On the other hand, the upper part of the food waste processor is provided with a suction fan 19 and an exhaust fan 19 'for sucking and discharging the outside air, and the suction fan and the heater 15 installed therein are external when necessary by a kind of fan heater function. The air is heated to flow in, and the exhaust fan 19 ′ deodorizes the gas (including steam) generated inside through the deodorizer and discharges it to the outside. A conventional deodorizer is a device for adsorbing malodor using activated carbon and is installed in the upper exhaust passage of the food waste processor.

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. Depending on the internal temperature and humidity conditions, the operation of the food waste processor may be controlled. 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 by 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 to maintain optimum fermentation or decomposition conditions of food waste.

However, the food waste processor of the above-described configuration cannot raise the humidity by simply operating the suction fan 19 and the exhaust fan 19 'when the humidity is lowered to 40% or less, and the heater 15 and the agitator. Although the operation of (16) can raise the humidity to some extent, it is not easy to raise the moisture in the fermentation tank 11, so that the fermentation conditions are poor because it eventually weakens the activity of the fermenting agent and leads to a dormant state. There is a problem. In particular, this problem occurs even more seriously if no new food waste is put in for 3 to 4 days after the addition of food waste.

The present invention is to solve the problems as described above, in the food waste processing apparatus of the structure that can agitate, reduce water evaporation and fermentation of food waste, when the odor is severe can improve the deodorizing performance of the deodorizing device, It is an object of the present invention to provide a food waste treatment device having a deodorizing and fermentation agent spray prevention means capable of preventing the fermentation conditions from being poor due to low humidity.
