A stirring blade 54 that is rotated by the rotating shaft 41 to stir the food waste in the storage box 53, and a dehumidifier 60 that cools and dehumidifies the hot air containing the water that has been supplied to the food waste and has finished drying. .

As shown in FIG. 5, the dehumidifying device 60 has an inflow pipe 62 having an inflow port 61 for dehumidified air, a cooling water inflow port 63, a cooling water discharge port 64 and a dehumidification air discharge port 6.
5 is provided, the inside of the device is partitioned by a ventilation plate 66 made of punching metal having a hole diameter of, for example, 2 to 4 mm, and the inflow pipe 62 is positioned higher than the water surface in the device so that the cooling water does not flow backward. I'm turning in.

In FIG. 2, 70 is a control panel,
The operation switch 71 and the crushing switch 72 are provided, and the food waste processing apparatus 1 is configured as described above. As shown in FIG. 6, the electric circuit of the main part of the food waste processing apparatus 1 has an operation switch 71 guided from a power source 77, and is connected from the operation switch 71 to relays 73, 74, 75 and a crushing switch 72, respectively. The crush switch 72 is connected to the relay 76. The relays 73 and 7
The contacts 73a, 74a, 75a and 76a of 4, 75 and 76 are respectively guided in parallel from a power source 77, the contact 73a to the dehydration motor 40, the contact 74a to the blower 51, the contact 75a to the heater 52, and the contact 75a. 76a is connected to the crushing motor 11, respectively.

Next, the operation of the above embodiment will be described. First, when the operation switch 71 is turned on, the relays 73, 74 and 75 are energized and the contacts 73a, 74
a and 75a are closed, the dehydration motor 40 operates, the dehydration rotor 31 rotates, and the stirring blade 54 starts stirring.
The blower 51 is operated and the heater 52 is energized to turn red, and hot air circulates in the drying device 50 as shown by the arrow in FIG. Then, when the crush switch 72 is turned on,
The relay 76 is energized, the contact 76a is closed, and the crushing motor 11 starts rotating.

In this state, when the garbage is supplied while supplying water to the charging port 13, the crushing rotor 12 crushes the garbage and turns it into fluid garbage from the crushing device 10 through the conveying pipe 20 and the dehydrating device 30. It is sent into the dehydration rotor 31 of. Here, since the transport pipe 20 is provided with the trap portion 20a, if water is accumulated in the crushing device 10, the odor generated before the transport pipe 20 does not flow out to the crushing device 10 side. .

The fluidized garbage sent into the dewatering rotor 31 is conveyed by the scraping plate 32 while being immersed in the water stored in the bottom of the dewatering device 30. Here, as the dewatering rotor 31 rotates, the raw garbage is fed into the gap between the inside of the dewatering rotor 31 and the fixed transport plate 35, and at this time, the raw garbage is finely compressed. The micro-compressed food waste is dehydrated together with the negative pressure of the water flowing out from the small holes of the dehydration rotor 31 when it is separated from the water surface stored in the bottom of the dehydrator 30. When the rotation further progresses and the minute compressed food waste inside the dehydration rotor 31 reaches the concave end portion 35a of the transport fixing plate 35, the dehydrated food waste is discharged from the discharge port 3
It is discharged from 6 to the duct 55.

In this case, the dewatering rotor 31 and the scraping plate 3
Although a small amount of food waste remains in No. 2, it is washed away when it re-enters the water stored at the bottom of the dehydration device 30, so that there is less food waste left in the dehydration rotor 31. The water stored in the bottom of the dehydrator 30 is discharged from the drain pipe 37 when the water level reaches a predetermined level or higher.
Since the trap portion 37a that folds back at a position higher than the water surface accumulated at the bottom of the is not provided, the odor does not flow out through the drain pipe 37, and the odor does not flow in from the outside. Absent. The raw garbage dehydrated by the dehydrator 30 is carried into the storage box 53 of the dryer 50 through the duct 55. On the other hand, the air sent from the blower 51 is heated as it passes through the heater 52 to become warm air of 60 ° C. to 90 ° C., and is supplied to the garbage that is agitated by the agitating blade 54 in the storage box 53. At this time, the water in the food waste evaporates and the food waste is dried.

In this case, the hot air supplied to the food waste removes water from the food waste to become high-humidity hot air.
0 is dehumidified through a process to be described later, becomes low-humidity air, and is sucked into the blower 51, and as shown by an arrow in FIG. 1, circulation in a sealed state is repeated. Therefore, the food waste in the storage box 53 is quickly dried, and the dried food waste is stored in the storage box 5.
A door (not shown) is opened together with 3, and it is taken out of the apparatus.
Explaining the process of dehumidification, as shown in FIG. 5, the high-humidity warm air indicated by the arrow A1 enters the device through the inflow port 61 of the dehumidifying device 60 and the inflow pipe 62. Arrow B
Since the first cooling water flows in from the inflow port 63 and is discharged from the discharge port 64 as shown by the arrow B2, it rises through the cooling water circulating in the device.

Here, when high-humidity hot air passes through the ventilation plate 66 provided in the cooling water in the apparatus, a large number of small air bubbles are generated, and when these air bubbles rise, the air is cooled and cooled. Moisture contained in the wind becomes condensed water, is absorbed by the cooling water and is dehumidified, and the warm air of the arrow A2 that has been cooled and dehumidified is discharged from the discharge port 65 and sent to the blower 51, and the blower 5 again.
The circulation from 1 to the heater 52 is repeated.

Next, in this embodiment, the garbage is fed while supplying water from the inlet 13, but as shown in FIG. 7, by connecting the inlet 13 to the drain 81 of the kitchen sink 80, the kitchen The kitchen waste (garbage) discharged from the sink 80 can be continuously processed. Further, in the present embodiment, the ventilation plate 66 made of punching metal is used in order to reduce the air bubbles of the high-humidity hot air rising in the cooling water in the dehumidifying device 60. However, instead of this, stirring or ultrasonic waves are used. It is also possible to divide the bubbles into smaller pieces or aerate the bubbles with an air stone.

[0026]

Since the present invention is configured as described above, it has the following effects. (A) Since each processing of food waste is continuously performed in a sealed state, discharge of odor to the outside can be suppressed. (B) Since the food waste dehydrated in the drying device is dried with warm air of low humidity while being stirred, the food waste is dried quickly.
