The operation of the garbage processing machine according to the embodiment will be described. First, a disposal bag 56 is set in a basket 54, garbage is put into the disposal bag 56, and the lid 40 is closed. , The processing time is set by the switch 76, and the drying processing is started. The rotary tank 16 is driven to rotate at high speed by the main motor 14, and separates water and oil contained in the garbage by the action of centrifugal force. Since hot air is constantly blown into the rotary tank 16, the water separated by the hot air is vaporized and discharged, and the garbage is heated and dried. The water and oil separated from the garbage are discharged from the upper portion of the rotary tub 16 to the outside by the centrifugal force of the rotary tub 16, and the tray 8 disposed outside the opening of the rotary tub 16.
Accumulate at 0.

The tray 80 is provided for temporarily storing the water and oil separated from the garbage by the rotation of the rotary tub 16, and has a ring surrounding the outside of the opening of the rotary tub 16 as shown in FIG. It is formed in a shape. A groove is provided on the inner peripheral edge of the tray 80 as shown in the figure, so that water and oil separated from garbage can be stored in the groove. The tray 80 is detachably attached so that dust and oil accumulated in the groove after the drying process can be washed at any time.

In the initial state in which the garbage is thrown in and the rotating tank 16 starts rotating, a lot of water is separated from the garbage, so that the water easily accumulates in the tray 80, but the hot air blown into the rotating tank 16 is The water also enters the tray 80 and heats the water to evaporate it into water vapor, which is discharged from the exhaust port 34 to the outside. The water that has accumulated in the tray 80 is eventually completely removed, and oil and dust carried along with the air from the inside of the rotary tank accumulate on the tray 80. Therefore,
After processing the garbage, only the oil remaining on the tray 80 may be washed. The garbage in the rotating tub 16 is dispersed by sticking to the inner wall surface of the basket 54 by centrifugal force generated by the rotation of the rotating tub 16, and the surface area exposed to the hot air is increased to be effectively dried. . Thus,
Separation of water and oil from the garbage, exhaustion by vaporization of the water by the hot air and drying of the garbage by the hot air effectively dry the garbage.

When the rotating tub 16 is rotated for a certain period of time and hot air is fed in to finish the drying of the garbage, the operation of the apparatus is stopped, and the garbage remaining in the rotating tub 16 is removed together with the waste bag 56 and the basket 54. Remove from and discard. After the drying process, the disposal bag 56 may stick to the inner surface of the basket 54 and may be difficult to be separated, so that the above-mentioned releasable material may be used as the disposal bag 56. Since the disposal bag 56 is preferably one that can effectively absorb moisture from garbage, a disposal bag 56 or the like having an inner surface made of a water-absorbing material and an outer surface made of a releasable material is preferable.

In an example of actual processing by the apparatus of the embodiment, the temperature of the hot air is 120 to 130 ° C. and the rotation speed of the rotary tank 16 is
When the processing was performed at 1500 rpm and 800 g of garbage, which is the average daily amount of garbage discharged at home, the processing was completed in about 3 hours. The garbage after the treatment became dry from the ground, and even if it was disposed of as ordinary garbage, there was no problem at all. Moreover, the volume of the garbage was reduced to about a quarter by the drying treatment, the weight was reduced, and the handling became extremely easy. It is difficult to treat fish and shellfish and the like because they contain oil together with water, but with this apparatus, the oil was also effectively removed. Thus, according to the apparatus of the present embodiment, garbage is processed in a completely dry state,
The garbage after treatment can be easily disposed of, the amount of refuse discharged can be effectively reduced, and refuse treatment that does not adversely affect the environment becomes possible.

The processing time for actually processing the garbage may be appropriately set depending on the amount of the garbage to be charged, the amount of water contained, and the like. It is preferable to set the rotation speed of the rotary tank 16 to a high speed at a point in time, and to switch the rotation speed to a low speed after a certain period of time. This is because noise or the like is generated when the rotary tank 16 is rotated at a high speed, and even after the moisture is separated to a certain extent, the rotation at a high speed is not so effective. As a method of controlling the rotation speed of the rotary tub 16 as described above, a method of setting and controlling a switching time, or a method of installing a humidity sensor at the exhaust port 34 to reduce the rotation speed to a low speed when the humidity of the exhaust gas becomes lower than a certain value, for example. It is possible to perform such a method as switching, or control such that the operation is automatically stopped when the humidity of the exhaust gas falls below a certain level.

In the apparatus of the above embodiment, a hot air delivery mechanism is provided inside the lid portion 40 so that the inner cover 62 and the rotary tank 1 are rotated.
6 were arranged close to each other, but this
This is because when the hot air blown into the basket 52 is reflected by the inner surface of the basket 52 and blows up, heat is exchanged with the outside air introduced from the suction port 74 to warm the outside air and enhance the heating effect of the outside air. In addition, the air is made to contact the outer surface of the motor 70 in the air duct 66 so as to circulate so that the heat generated by the motor 70 driving the blower fan 68 can also be used for heating the outside air.

In the apparatus of the embodiment, when removing the basket 54, it is only necessary to pull it out of the bucket 52.
The bucket 52 can be taken out of the rotary tank 16 by pulling it up with the flange. Thus, the bucket 52 and the basket 54 can be easily taken out and washed. When the inside of the fixed drum 22 needs to be cleaned, the rotating tank 16 is
By pulling up from 1, the rotating tank 16 can be easily removed and washed. In the embodiment, the engagement pin 50 is used.
Although the rotary tub 16 is mounted on the rotary support plate 21 in this example, the rotary tub 16 can be detachably configured by a method other than the engagement pin 50, such as a screw mounting method or a pin engagement locking method.
