Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste processing machine for processing kitchen waste such as general domestic food waste.

[0002]

2. Description of the Related Art As a conventional food waste disposer, a disposer for crushing food waste and discharging it into sewage, or crushing food waste
There is a garbage dehydrator that dehydrates and collects. Disposers pollute rivers in areas without sewage treatment plants and cause environmental pollution. On the other hand, since the raw garbage dehydrator collects dehydrated raw garbage, it does not directly cause environmental pollution. However, if the collected raw garbage is left as it is, it easily decomposes and produces a foul odor. Therefore, deodorized and collected food waste may be stored at low temperature, or it may cause environmental pollution such as having to be frequently sent to a public garbage collection site for disposal.
There is a problem that the processing after processing with the processing machine is troublesome.

In order to solve this problem, there has been considered a food waste processing machine that reduces the original volume and weight of the food waste by crushing and drying it, and prevents spoilage. The structure of the food waste disposal machine will be described with reference to FIG. explain. Reference numeral 1 denotes a heat insulating container (in FIG. 6, an example is a vacuum heat insulating container having an inner wall and an outer wall and a space therebetween is evacuated), and 2 is a food waste container installed in the heat insulating container. A fixed blade 4 and a rotary blade 5 are provided in the garbage storage container 2 for crushing and stirring the garbage. The fixed blade 4 is provided on the inner wall of the garbage storage container 2, and the rotary blade 5
Is fixed to a rotary shaft 6 protruding from the bottom surface of the garbage storage container 2. Above the food waste container 2, a heater 8 and a fan 9 are provided as food waste heating means. 10 is a fan motor. A condenser section 11 is provided on the outer peripheral portion of the heat insulation container 1.
And the blower fan 12 is installed. Reference numeral 14 is a drive motor for rotating the rotary blade, which is connected to the rotary shaft 6 via a reduction gear 15. A condensed water outflow pipe 1 is provided below the condensing section 11.
8 and an exhaust pipe 19 are provided. Condensed water outflow pipe 1
A condensed water container 20 is provided at the tip of 8. A deodorizing device 21 (or a catalyst device) is provided behind the exhaust pipe 19. Reference numeral 22 is a food waste processing machine main body, and 23 is a lid. The lid 23 is supported by a hinge 24 and can be freely opened and closed on the food waste processing machine main body 22, the packing 3 is sandwiched, and the lid 23 and the food waste processing machine main body 22 are fixed by a latch-type handle 25 to form a food waste storage container. 2 becomes a closed state.

[0004] In the garbage treating machine configured as described above, the food waste put in the food waste container 2 is crushed and stirred between the rotary blade 5 and the fixed blade 4. At the same time, it is heated by the heater 8 and the fan 9. Water vapor containing odorous components is generated from the garbage, flows into the condensing unit 11, is cooled by the blower fan 12, is condensed, and is accumulated in the condensed water container 20 by the condensed water outflow pipe 18. On the other hand, the water vapor containing the odorous components that cannot be completely condensed is discharged from the exhaust pipe 19 to the deodorizing device 21.
And is guided to a catalyst device to purify odorous components. The crushed and dried food waste remains in the food waste container 2, but since the bulk is reduced and the water activity is reduced due to drying,
Even if it is put in the raw garbage storage container 2 as it is, it does not decompose or mold. Therefore, the garbage container 2
You can put the garbage on top of the dried garbage one by one and dry it until it is full. Then, the dry food waste remaining in the food waste container 2 and the condensed water accumulated in the condensed water container 20 are periodically collected and discarded.

[0005]

However, in the case of this food waste disposer, the heat insulating container 1 is used to shorten the drying time. Not done, so lid 2 after drying
There was a problem in safety, such as the possibility of touching the high-temperature storage container 2 when opening 3. Further, since the temperature inside the heat insulation container 1 naturally cools for 1 hour or more, if the drying time is combined, it is necessary to wait a long time until the treated dust is taken out, which is inconvenient. . It is conceivable to provide an air intake for shortening the cooling time, but in that case, the inside of the heat insulating container is not closed and the drying time is extended, and the odor at the time of drying is constantly released. The present invention solves the above problems and, by pulverizing and drying food waste without polluting the environment, reduces the original volume and weight of the food waste and prevents spoilage, and yet has excellent safety and operability. The purpose is to provide a garbage processor.
