It promotes the crushing of garbage in the processing tank b and the decomposition by high temperature fermentation.

There is also a type of rotating the rotating shaft f in both forward and reverse directions in order to prevent the fibers contained in the garbage from getting entangled in the stirring blade c.

[0005] In most cases, all of the garbage processing products in the processing tank b are discharged by manually opening the lid e of the processing tank b and taking out the garbage.

[0006]

However, in such a conventional food waste treating apparatus a, the stirring blade c is used.
Often, the garbage is discharged from the discharge port without being sufficiently decomposed into powder by the rotation of the blade, and moreover, the blade-like stirring blade c is liable to be entangled with fibrous material and the like, and the rotation axis f can be easily rotated. It is not allowed to stir during rotation and discharge during reverse rotation.

Further, the manual work for completely discharging the garbage processing products in the processing tank b requires a great deal of labor, and its improvement is desired.

The present invention is based on the use of a stirrer provided with spiral stirring blades around the rotary shaft, and discharges only the treated waste products that have been sufficiently stirred, decomposed into powder and dried. It is an object of the present invention to provide a food waste treatment device which can be discharged from an outlet and can enhance the reliability of the device.

[0009]

In order to achieve the above object, the apparatus for treating garbage according to the present invention comprises a stirrer provided with a spiral stirring blade around a rotating shaft in a treatment tank for treating with fermenting bacteria. The raw garbage treated product in which the raw garbage input port and the stirring blade of the stirring body are located in the vicinity of the end of the processing tank on the side opposite to the direction in which the raw garbage is fed by the rotation of the rotating shaft in one direction, and the raw garbage is treated. And a discharge port for discharging.

It is to be noted that the treatment tank is equipped with a weir body that rises from the wall surface of the treatment tank and separates the raw garbage being processed from the discharge port, so that the untreated raw garbage is inadvertently discharged. It is desirable to prevent this.

Further, it is desirable that the rotary shaft is rotatable in the other direction, because it is possible to automatically discharge all the food waste treated products.

There is an exit. Therefore, relatively large garbage immediately after being charged, heavy garbage, and moisture-containing garbage are always sent in the direction opposite to the discharge port by the spiral stirring blade, and therefore In the state of a light garbage treated product that has been thoroughly stirred, dried into fine powder, and decomposed,
Only the overflowed material can be discharged from the discharge port, and the reliability of the apparatus can be improved, and since the stirring blade has a spiral shape, the entanglement of the fibrous material and the like can be reduced compared to the blade-shaped one.

Further, in the invention of claim 2, when the processing tank comprises a weir body which rises from the wall surface of the processing tank and separates the raw garbage being processed from the discharge port, the weir body is stirred and decomposed. Inadequate garbage can be prevented from being inadvertently discharged from the discharge port.

Further, in the invention of claim 3, when the rotary shaft can be rotated in the other direction as well, the reverse rotation of the other direction sends the raw garbage processing product toward the discharge port and discharges it. It is possible to automate all discharges, and can be effectively used for maintenance, long-term non-use, etc. For example, one motor that rotates the rotating shaft has two functions of stirring / disassembly and discharge. It can be done.
