In this structure, the raw garbage and the decomposition processing auxiliary material (hereinafter, also referred to as "auxiliary material") are put into the processing tank through the charging port and accommodated therein, and provided on the stirring shaft by the rotation of the stirring shaft. The stirring blades rotate in the treatment tank, the food waste and auxiliary materials are agitated and mixed, and the organic substances that make up the food waste are decomposed into carbon dioxide gas and water by the action of the microorganisms attached to the auxiliary materials. The decomposed product which is the residue after being decomposed and decomposed is discharged from the discharge port at the lower part of the treatment tank or stored in the discharge storage tank.

As microorganisms used for the microbial decomposition treatment of food waste, aerobic bacteria having a high decomposition effect are mainly used. Therefore, in the decomposition reaction system inside the treatment tank, the presence of oxygen for maintaining the activity of aerobic bacteria is an important condition, and the introduction of air from outside the treatment tank,
Also, it is important to secure the air permeability in these contents by stirring and mixing the food waste and auxiliary materials in the treatment tank. In addition, at the same time as stirring, by performing a crushing process to make raw garbage into pieces that are more easily decomposed,
The surface area, which is a factor that promotes the reaction of food waste with microorganisms and air, increases, and the decomposition further proceeds. Therefore, stirring and crushing in the processing tank of the food waste processing device are important conditions that affect the level of the decomposition processing function of food waste.

However, according to the conventional method, the contents such as food waste are only agitated by the rotating agitating blades stored in the treatment tank, so that the food waste is mixed with auxiliary materials and microorganisms. There is a limit to the degree and the degree of crushing of food waste, and it is not possible to supply oxygen sufficiently to microorganisms. Therefore, there is a limit to the efficient decomposition of food waste.

Further, when the water produced by the decomposition treatment accumulates in the treatment tank, the efficiency of contact of the garbage in the water-immersed portion with oxygen is lower than that in the non-immersed portion, and the decomposition treatment speed is reduced. There was a problem of letting it.

Further, in the conventional apparatus, it is necessary to provide a special discharge port or a discharge storage tank for discharging the decomposed product after the decomposition process, and in order to move the decomposed product from the inside of the processing tank to these discharge ports or the like. However, there are some inconveniences such as the need to push the decomposed product by the operation of the stirring blade.

Further, in the conventional apparatus, when the processing tank is opened during the operation for the purpose of additionally supplying auxiliary materials, the stirring blade may continue to rotate in the tank, which also contributes to the safety of work. There was a problem.

The object of the present invention is to improve the crushing effect of food waste in the treatment tank and the stirring effect of the food waste and the decomposition treatment auxiliary material, excluding the above-mentioned drawbacks of the prior art. An object of the present invention is to provide a food waste processing device which can improve the efficiency of food waste processing and can easily discharge the decomposed products after the decomposition processing from the inside of the processing tank.

Another object of the present invention is to provide an apparatus for treating food waste, which can prevent immersion of food waste or the like due to water produced by the decomposition treatment and prevent a decrease in the decomposition treatment speed.

[0012] Still another object is to provide a food waste processing apparatus which further enhances the safety of work when throwing in food waste or the like.
