Description

Deodorization system of food waste treatment device according to humidity and agitation

The present invention relates to a deodorization system of a food waste treatment device according to humidity and agitation, and more specifically, to ferment by heating and stirring food waste disposed of at home, and the gas and water vapor discharged after deodorization are collected and the waste is collected. In the food waste treatment apparatus for waste disposal or composting, it relates to a deodorization system of a food waste treatment apparatus according to humidity and agitation, which can be effectively deodorized from steam and gas discharged according to agitation and humidity.

In general, each home or restaurant, such as the leftover (food waste) is discharged every day, such residue is used as a livestock feed or is simply thrown away by simply filtering through the strainer. 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 contaminates the surrounding drinking water or air. have.

The food waste disposal window of the example shown in FIG. 1 is provided with an input door 12 for inputting the residue and an discharge door 21 for removing the residue after the treatment. The inside of the main body is provided with a fermentation tank 11 for processing the residue and a deodorizer (not shown) 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 the residue is removed or configured to remove the residue through the opening / closing door 22.

Inside the fermentation tank 11, a stirrer 15 is rotatably mounted, and the residue is decomposed and processed by stirring and fermenting the fermentation agent and the residue introduced from the outside. The stirrer 16 is rotated forward and backward 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 portion of the food waste treatment apparatus is installed intake and exhaust fan 19 for sucking and discharging the outside air, the suction fan and the heater 15 installed therein is heated by the outside air if necessary by a kind of fan heater function inflow The exhaust fan deodorizes the gas (including water vapor) generated inside through the deodorizer and discharges it to the outside. Conventional deodorizers are devices for adsorbing odors using activated carbon and are installed in the upper exhaust passage of the food waste disposal apparatus.

However, although the food waste treatment device of the above-described configuration mechanically agitates and ferments, it increases the efficiency of the fermentation and shortens the treatment time. However, the odor of the mixed gas of the gas and water vapor generated during the agitation is a normal activated carbon deodorizing device. It is difficult to remove only, and there is a problem that excessive ozone is generated even when an ozone generator is used, or it is operated in a state that is not optimal for deodorization and thus cannot play a role.

The present invention is to solve the above problems, to provide a deodorization system of food waste treatment apparatus according to the humidity and agitation, which can be effectively deodorized by maintaining the optimum state according to the stirring and humidity from the steam and gas discharged Its purpose is to.
