[0022]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

(Embodiment 1) FIGS. 1 and 2 show an apparatus for drying food waste according to Embodiment 1 of the present invention.

In FIG. 1, reference numeral 1 is a main body of a raw garbage drying machine, 2 is a raw garbage storage section arranged in the main body 1, 3 is raw garbage stored in a raw garbage storage section 2, 4 is raw garbage 3 A heating heater 5 for heating the heating element 5 is a blower fan for sending hot air through the heating heater 4 in the direction of the garbage 3, and the heating heater 4 and the heating heater 6 constitute heating means 6. 7 is a stirring means for stirring (and crushing) the raw garbage 3 in the raw garbage storing section 2, 8 is a main body lid for attaching and detaching the opening of the raw garbage storing section 2, 9 is a packing for keeping airtight, and 10 is the raw garbage 3 Is a discharge means including a discharge fan 11 for discharging the exhaust of steam, odorous components, etc. generated during the dry weight reduction of the main body 1, and the exhaust outlet 12, the discharge path 13 and the exhaust path 12 above the garbage storage unit 2. It is designed to be discharged to the outside of the main body 1 via a catalytic deodorizing device 14 capable of removing odorous components in exhaust gas.

Reference numeral 17 is an intake port which constitutes an intake path into the garbage storage unit 2. Reference numeral 18 denotes a plate constituting the catalytic deodorizing device 14, which carries a substance such as platinum for deodorizing the odor of the exhaust gas passing therethrough by an oxidation reaction. 1
Reference numeral 9 is a catalyst heating means for heating the plate 16.

Numeral 15 is a detection means provided in the middle of the discharge path 13 to detect the temperature of the discharged exhaust gas and detect the end of drying. Reference numeral 16 is a control means for controlling the operation of the garbage drying processing machine by the detection by the detection means 15. In this embodiment, the control means 16 controls so as to substantially increase the discharge capacity of the discharge means 10 after detecting the completion of drying of the garbage. Specifically, the capacity of the discharging means 10 itself is increased, that is, the rotation speed of the discharging fan 11 that constitutes the discharging means 10 is increased. However, the present invention is not limited to this, and any indirect means may be used as long as it substantially increases the discharge capacity after detection of completion of drying of raw garbage.

In the above construction, the raw garbage 3 in the raw garbage storage unit 2 is heated by the heating means 6 and at the same time the stirring means 7 is heated.
Is dried with stirring (and crushing). Vapor and odorous components generated in the drying process of the raw garbage 3 are sucked by the discharge fan 11, pass through the discharge path 13, and are in the catalyst deodorizing device 14 between the surface of the plate 16 heated by the catalyst heating means 17. The odorous components are deodorized by the catalytic reaction and are discharged to the outside of the main body 1. At this time, since the inside of the garbage storage unit 2 is depressurized at the same time, outside air is introduced from the outside through the intake port 17. Then, when the drying is completed, the amount of water in the exhaust gas decreases, so the heat capacity of the exhaust gas also decreases, and the exhaust gas temperature passing through the exhaust path 13 rapidly decreases. This is detected by the detection means 15 and a signal is transmitted to the control means 16 to complete the drying process.

In this embodiment, as shown in FIG.
After the completion of the drying process, that is, after detecting the completion of drying the raw garbage, the process proceeds to a cooling process for cooling the dried raw dust. At this point, the control unit 16 increases the rotation speed of the discharge fan 11 to increase the exhaust flow rate of the discharge fan 11. It is controlled to increase. For example, the number of revolutions can be changed by utilizing a voltage change, a frequency change, and a winding specification change.

As a result, the amount of outside air entering the garbage storage unit 2 during and after the drying process of the garbage 3 is changed, the outside air amount is kept small during the drying process, and more heat energy than necessary for drying is applied. I'm losing things. After the drying is completed, the amount of outside air entering is increased, and the odor remaining in the garbage 3 is quickly released to the outside through the catalytic deodorizing device 14,
The unpleasant odor of the garbage 3 can be reduced quickly and significantly.

Further, after the drying is completed, in order to end the whole operation, it is necessary to lower the temperature in the garbage storage unit 2 and wait until the level at which the main body lid 8 is opened and there is no fear of being burned. . Therefore, by passing a large amount of outside air through the inside of the garbage storage unit 2, the temperature lowering speed is accelerated, and the entire operation of the garbage drying processing machine can be ended earlier. Therefore, it leads to a total reduction in energy.

(Embodiment 2) Regarding Embodiment 2 of the present invention,
This will be described with reference to FIG. The same parts as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

In the figure, the control means 16 controls the resistance varying means for varying the path resistance in the intake path or the exhaust path 13 to the garbage storage unit 2. In this embodiment, the variable resistance means is constituted by providing a throttle means 20 on the downstream side of the catalytic deodorizing device 14 in the discharge path 13 from the garbage storage 2 to the discharge means 10. As a specific example of the throttle means 20 for controlling the path resistance, a method of changing the path resistance by varying the valve opening using an actuator in a structure like a throttle valve in the path (not shown). ).

With this configuration, the resistance variable means for varying the path resistance during the drying process, that is, the path resistance of the throttle means 20 is controlled to be large, the amount of outside air introduced is kept small, and after the drying process is completed. On the contrary, it is possible to increase the amount of outside air introduced after the completion of drying is detected by the discharging means 10 having the same capacity by controlling to reduce the path resistance of the restricting means 20 without changing the capacity of the discharging means 10. is there.

A diaphragm means 20 for controlling the path resistance.
It is needless to say that the same action and effect can be obtained even if it is provided in the intake path connected to the intake port 17.

(Third Embodiment) The configuration of the third embodiment of the present invention is the same as that of FIG. 1 except for the control method, and therefore the description thereof is omitted.

In FIG. 4 showing the control method, the stirring means 7 is normally operated during the drying process, and the raw garbage 3 is stirred while stirring.
Is dried. Similarly, in addition to increasing the discharging capacity of the discharging means 10 after the completion of drying is detected by the drying completion detecting means 15, the stirring means 7 is also operated continuously.

As a result, even after the completion of drying by the detection means 15, the stirring means 7 is operated in the raw garbage storage unit 2 and the capacity of the discharge means 10 is increased. Due to both the effect of increasing the discharge capacity and the agitation of the dried garbage, the odor can be expelled from the garbage 3 more quickly, and the odor of the garbage 3 can be significantly reduced.

(Embodiment 4) The configuration of Embodiment 4 of the present invention is the same as that of FIG. 1 except for the control method, and therefore its explanation is omitted.

In FIG. 5 showing the control method, during the drying step, the stirring means 7 is operated to dry the garbage 3 while stirring. Similarly, in addition to increasing the discharging capacity of the discharging means 10 after the detection of the completion of drying by the detecting means 15, the stirring means 7 is continuously and intermittently operated after the completion of drying.

When the stirring means 7 is continuously rotated, dried raw garbage is liable to idle and the odor of the raw garbage 3 cannot be efficiently expelled in many cases. Therefore, by intermittently operating the stirring means 7, it is possible to prevent the garbage 3 from idling, and it is possible to reduce the total energy compared to continuous operation.

(Fifth Embodiment) The configuration of the fifth embodiment of the present invention is the same as that of FIG. 1 except for the control method, and therefore the description thereof is omitted.

In FIG. 6 showing the control method, the detection means 1
After the completion of drying by 5, the discharging capacity of the discharging means 10 is increased, and in addition, the stirring means 7 is intermittently operated in the raw garbage storage unit 2 to stir the dried raw garbage, so that the odor can be generated more quickly. You can get out of 3 efficiently. Further, at this time, the heating means 6 is provided only when the stirring means 10 is operating.
Is controlled to drive. This makes the garbage 3
The temperature rises a little and the odor becomes more likely to be expelled. As a result, 3
The odor of the dried food waste 3 can be further significantly reduced.

(Sixth Embodiment) The configuration of the sixth embodiment of the present invention is the same as that of FIG. 1 except for the control method, and therefore the description thereof is omitted.

In FIG. 7 showing the control method, the discharging means 10 is intermittently operated after the drying is completed, and the catalyst heating device 19 of the catalyst deodorizing device 14 is further operated during the operation of the discharging means 10.
I am trying to energize. As the odor is discharged by the discharge means 10, the amount of odor decreases in sequence. At this time, if the discharging means 10 and the catalyst heating device 19 are always operated continuously, there is much waste. Therefore, the discharging means 10 and the catalyst deodorizing device 14 (catalyst heating device 19) are intermittently operated to efficiently reduce the odor of the garbage 3.

(Embodiment 7) Regarding Embodiment 7 of the present invention,
This will be described with reference to FIG. The same parts as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

In the figure, a catalyst deodorizing device 14 and an adsorbing deodorizing device 21 are provided in series in a discharge path 13 from the garbage storage 2 to the discharging means 10, and the catalyst deodorizing device 14 is put into a non-operating state after completion detection. It is controlled to become. This is because the moisture contained in the odor generated from the raw garbage 3 after the drying is extremely smaller than the moisture generated during the drying, and therefore, the deodorization can be performed only by the adsorption deodorization device 21 without operating the catalyst deodorization device 14. It is possible enough. Therefore, after the catalyst deodorizing device 14 is operated and the drying is completed, energy for heating the catalyst is not required, and energy saving can be realized.

(Embodiment 8) As to Embodiment 8 of the present invention,
This will be described with reference to FIG. The same parts as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

The switching valve 22 is switched to the catalyst deodorizing device 14 side, and the switching valve 22 is switched to the adsorption deodorizing device 21 side after the completion of drying. This is because when the catalyst deodorizing device 14 and the adsorption deodorizing device 21 are arranged in series, the pressure loss of the entire discharge path 13 increases. Therefore, it is necessary to use the discharging means 10 having a high capacity, and this can be prevented.

(Embodiment 9) Regarding Embodiment 9 of the present invention,
This will be described with reference to FIG. The same parts as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

In the figure, a discharge path 13 from the garbage storage unit 2 to the discharge means 10 is composed of an adsorbing deodorizing device 21, a catalyst deodorizing device 14, and a discharging means 10 in that order, and a catalyst heating means 19 of the catalyst deodorizing device 14 is The adsorption / deodorization device 21 is provided at a position where it can be heated.

By deodorizing the desorbed components with, the odor is not emitted to the outside, and the adsorption / deodorization device 21 is regenerated.
1 can be used without replacement.

The embodiments described above are not limited to the individual embodiments, but can be implemented by appropriately combining them.

Needless to say, the various controls in each embodiment can be controlled by a plurality of control means instead of the single control means 16.
