Embodiments of the present invention will now be described with reference to the drawings. Embodiment 1 FIG. The first embodiment shown in FIGS. 1 to 6 relates to a garbage drying processing apparatus for drying garbage generated in ordinary households and restaurants without crushing. The main body 1 of the kitchen refuse drying treatment apparatus is constituted by a closed structure and an open structure. In the sealed structure,

At the lower end of the draining basket 9, an airflow blowing structure 10 is provided as a bottom structure that holds the kitchen waste 3 and allows water to flow down and airflow through. Above the open portion at the top of the processing container 4, one end side is a hinge 11.
The closed lid 2 is connected to the processing container 4 by opening the closed lid 2. The garbage 3 can be put into the drainage basket 9 of the processing container 4, and the closed circulating air passage 7 can be closed by closing. At the edge of the opening of the hermetic circulation air passage 7 which comes into contact with the hermetic lid 2 in a closed state, a seal 12 for performing an airtight function is provided.
And a lock mechanism 13 for locking the closed state of the sealing lid 2 is also provided. Further, a damper 14 for holding the closed lid 2 in an open state is also attached to the hinge 11 portion.

The bottom side of the processing container 4 is connected to a chamber 15 in which a blower 5 and a heater 1 are connected.
6 and a kitchen waste receptacle 17 are incorporated. Blower 5
Has an operating point of a static pressure of 100 mmH ₂ O and an air flow rate of about 1 m ³ / min, forms an airflow to be sent to the airflow blowing structure 10 of the processing container 4, and raises the temperature of the airflow between the air outlet and the airflow blowing structure 10. A heater 16 of a sheathed heater or a ceramic heater having an output of several hundred watts is provided as a heating means. The kitchen waste receptacle 17 is a container body having an open top, and the chamber 15 is formed by a shelf structure or the like so that the open part faces directly below the airflow blowing structure 10 of the processing container 4.
Is held within.

The suction port of the blower 5 faces a downstream end of a communication air passage 18 connecting the downstream side of the condenser 6 and the chamber 15. The closed circulating air passage 7 of the portion constituted by the condenser 6 is formed substantially vertically in the vertical direction on the downstream side of the processing vessel 4, and is connected to the chamber 15 by a communication air passage 18 at a lower portion. The condenser 6 is configured such that only the condenser 19 faces the closed circulation air passage 7. The condenser 19 of the condenser 6 is made of a metal having good heat conductivity having corrosion resistance and heat resistance, and its inner surface facing the closed circulation air passage 7 is provided with a water-repellent material 20 (a fluororesin or a tetrafluoroethylene resin). ), And a fibrous or porous water-absorbing material 21 is detachably attached to the outer surface facing the open structure. The blower 5 blows the air into the chamber 1
5, the processing vessel 4, the condenser 6, and the connecting air passage 18 flow in this order;
The closed circulation air passage 7 is circulated. As shown in FIG. 2, it is desirable that the closed circulation air path 7 employs a heat insulating structure 22 for all paths except the condensing section 19 from the viewpoint of drying efficiency.

Below the condenser 19 inside the closed circulation air passage 7 of the condenser 6, a drain tank 23 having an open top as a water treatment part is arranged so as to receive the water condensed in the condenser 19. ing. The drain tank 23 is configured to be able to be taken in and out of the main body 1 by inserting and removing, and when inserted, airtightness with the main body 1 is maintained. In addition, a water level detecting means (not shown) for detecting a water level can notify that the water is full when the water is full.

The open structure is constituted by a container structure having an open upper part, in which water can be stored in a lower part.
Is part of. The cooling device 8 includes a pump 24 that sucks up the stored water and supplies water from above to a water-absorbing material 21 that is installed outside the condensing portion 19 of the condenser 6 that forms the inner portion of the open structure. A ventilation fan 25 for ventilating the inside of the structure is provided, and the condenser 19 of the condenser 6 can be continuously cooled by water. The ventilation fan 25 is provided at the upper part of the open structure, takes in air outside the device,
The air is blown downward from above along the water absorbing material 21,
Promotes cooling.

The structural part of the closed circulation air passage 7 has corrosion resistance,
It is made of a plastic (PP resin or PS resin) or a stainless steel plate capable of obtaining heat resistance (withstanding about 120 ° C.), and the blower 5 and the heater 16 are also provided with corrosion resistance. The term “corrosion resistance” as used herein refers to resistance to ammonia, amine, methyl carbane, hydrogen sulfide, acetic acid, ethyl acetate, aldehyde, oils and fats contained in the kitchen waste 3.

A control circuit 26 is incorporated at an appropriate place outside the closed circulation air passage 7 of the main body 1 to control the operation of the drying operation based on the temperature information from the temperature sensors 28 and 29 when the operation switch 27 is turned on. The temperature sensor 28
Is for detecting the temperature of the airflow blown into the processing container 4, and the temperature sensor 29 is for detecting the temperature of the airflow before flowing into the condenser 6 having exited from the processing container 4.

This garbage drying treatment apparatus is basically for drying garbage 3 at a low temperature (50 ° C. to 90 ° C.). Open the sealing lid 2 and remove the kitchen waste 3 into the drainage basket 9 of the processing container 4.
When put into the kitchen, the water contained in the kitchen waste 3 flows down,
It is received by the kitchen waste receptacle 17. When the opened lid 2 is closed, the contact switch 30 is closed and the operation is in a standby state. When the operation switch 27 is turned on, the control circuit 26
Drives the blower 5 to form a circulating airflow in the closed circulating air passage 7. At the same time, the temperature of the airflow blown into the processing container 4 is detected by the temperature sensor 28, and this temperature is, for example, 7
The power supply to the heater 16 is controlled so as to be 0 ° C. to 80 ° C. In addition, while the temperature detected by the temperature sensor 29 is lower than the set temperature, a process for not operating the cooling device 8 is performed.

Therefore, immediately after the operation switch 27 is turned on,
The blower 5 and the heater 16 operate, and the cooling device 8 is stopped. Since the blower 5 generates heat by the internal coil during its operation, the blower 5 together with the heater 16 has a temperature of 70.degree.
It contributes to generating an airflow at a temperature of 80 ° C. In this way, an air flow having a temperature of 70 ° C. to 80 ° C. is generated, and the processing vessel 4
Is blown into the garbage 3 in the processing container 4 from the airflow blowing structure 10. The kitchen waste 3 put into the processing container 4
Is a conical shape, so that the airflow blown from the lower airflow blowing structure 10 is diffused according to the shape of the processing container 4 so as to prevent the kitchen waste 3 from sticking due to its own weight. Pass through the gap of the kitchen waste 3 almost uniformly. During this time, the airflow continuously removes the moisture of the kitchen waste 3 and circulates in the closed circulation air passage 7.

While the temperature detected by the temperature sensor 29 is equal to or lower than a predetermined temperature, the cooling device 8 is stopped to give priority to increasing the temperature of the airflow. When the temperature detected by the temperature sensor 29 exceeds the predetermined temperature, the control circuit 26 operates the cooling device 8 to cool the condenser 19 of the condenser 6 from outside. That is, the pump 24 operates to pump up the water stored in the open structure, supply the water to the water-absorbing material 21 from above the condensing section 19, and vaporize and cool the entire condensing section 19. At the same time, cooling is promoted by the operation of the ventilation fan 25. The steam in the airflow flowing through the condenser section 19 of the condenser 6 in the closed circulation air passage 7 that has been vaporized and cooled is condensed by utilizing the heat of vaporization in the condenser section 19 and condensed into the condenser section 19 to become water droplets. The water droplets condensed in the condensing section 19 are dropped by their own weight without being stagnated because the water repellent coating is applied to the condensing section 19, and are received in the drain tank 23 below.

The low-temperature, low-temperature airflow that has passed through the condenser 6 is sucked into the chamber 15 from the communication air passage 18 by the blower 5 and blown into the processing container 4. The air flow blown into the processing container 4 is supplied with heat from the blower 5 and a heater 16.
Is a low humidity stream at a temperature of 70 ° C to 80 ° C due to heat received from However, if the temperature of 70 ° C. to 80 ° C. is obtained by receiving the heat from the blower 5, the heater 16 is not energized.

In this way, the water in the kitchen waste 3 in the processing container 4 is continuously removed and dried. As the drying process of the kitchen waste 3 proceeds, the temperature of the airflow before entering the condenser 6 increases. And the temperature sensor 29
When the detected temperature is equal to or higher than the predetermined temperature, the control circuit 26 determines that the drying process has been completed, and
6. The operation of the cooling device 8 is stopped. The kitchen waste 3 that has been dried may be opened and closed, and the whole draining basket 9 may be taken out and appropriately processed. The water collected in the drain tank 23 during the drying process is drawn out of the drain tank 23 and drained as appropriate. The kitchen waste dropped into the kitchen waste receiver 17 evaporates due to an air current in parallel with the drying process of the kitchen waste 3, and does not need to be processed.

A characteristic of the kitchen waste processing apparatus is that the kitchen waste 3 in the processing container 4 is dried without being crushed by blowing air at a relatively low temperature. In the drying treatment by blowing high-temperature air such as 100 ° C. to 120 ° C., if garbage, plastic containers, rubber bands, and the like are mixed in the garbage 3, they are burnt or deteriorated by heat and must be separated in advance. If drying treatment is performed with these mixed,
From the dried garbage 3, a strong irritating odor accompanying the burning or deterioration of plastic or rubber is emitted. In the high-temperature treatment, the volatile components contained in the garbage 3 also have a large volatilization amount, and the condensed water also has an odor due to the volatile components, which impairs usability.
Furthermore, since the amount of water vapor generated due to the high-temperature treatment is large and the internal pressure of the apparatus is large, it is necessary to adopt a firm airtight holding structure and the structure becomes complicated.
The above-mentioned problems are all eliminated by the drying treatment by blowing air at a temperature of up to 90 ° C. For example, even if a plastic container is mixed, it can be separated from garbage after drying if necessary without burning.

Further, since the kitchen refuse 3 is dried by circulating an air flow in the closed circulation air passage 7, the odor does not leak into the room or the surroundings, and the energy consumption can be reduced in combination with the drying at a low temperature. The dried garbage 3 is reduced in weight, and has a clean and easy-to-handle processing form that does not have odor and does not easily rot. By using tap water or the like for cooling the condensing section 19, no unpleasant odor is generated at the time of evaporation, and furthermore, by supplying / stopping water, the airflow in the closed circulation air passage 7 is controlled without controlling the blower 5 and the heater 16. The temperature can be arbitrarily controlled, and the configuration of the cooling device 8 can be made simple and small. Further, since the water repellency is imparted to the condensing portion 19 of the condenser 6, there is no possibility that the condensed water stays in the condensing portion 19 while adhering thereto and is re-vaporized by the heat of the airflow. Therefore, the moisture in the kitchen waste 3 in the processing container 4 can be continuously removed without lowering the drying speed.

In the drying state, the blower 5 is located on the downstream side of the processing container 4, so that the blower 5 is not directly exposed to the organic gas contained in the garbage 3, so that corrosion of the impeller and the like can be avoided. Moreover, the heat generated by the blower 5 can be effectively used for drying the garbage 3. In addition, since the blower 5 is disposed below the processing container 4, the center of gravity of the apparatus is located below the stable area, and the apparatus hardly falls. When the blower 5 is built in the sealing lid 2 or the like, not only the device becomes unstable, but also the weight of the sealing lid 2 increases, the operability deteriorates, and the configuration of the sealing circulation air passage 7 becomes complicated, The pressure loss will also increase. In this garbage drying treatment apparatus, since the lid 2 is located at the upper part, the opening and closing operation is easy, and the garbage 3 can be easily taken in and out.

As shown in FIG. 3, the cooling device 8 may be configured by filling a heat storage material 31 such as water into an open structure, or may be configured by an electronic cooling device 32 such as a Peltier device as shown in FIG. Alternatively, a heat pump type configuration as shown in FIG. 5 may be employed. The cooling device 8 using the heat storage material 31 such as water has a simple configuration, and the cooling capacity can be easily improved by introducing a cooling material such as ice. Further, the cooling device 8 using the electronic cooling element 32 can promote simplification and downsizing of the configuration, and the heat pump type cooling device 8 can increase the cooling capacity and shorten the drying processing time. . As a simpler cooling device, as shown in FIG.
It can also be composed only.

By adopting the above, the garbage 3 in the processing container 4 can be floated by the dynamic pressure of the air flow to form a gap, and ventilation can be provided between the garbage 3, and the progress of the moisture removal of the garbage 3 can be more quickly. can do.

Further, as shown in FIG.
At the center of the pipe, a pipe 37 having a closed end and having a blowout hole 36 on the outer periphery may be erected so that airflow can be blown. Further, as shown in FIG. An outer peripheral blowing port 38 for blowing may be formed. If the former configuration is adopted, airflow can be blown radially from the outlet 36 of the pipe 37, and a heated low-humidity airflow can be blown into the upper part of the kitchen waste 3 as well. Drying can be promoted by bringing the air flow into uniform contact with the surface. In addition, if the latter configuration is adopted, the airflow can be blown into the processing container 4 also from the outer peripheral inlet 38, and the heated low-humidity airflow can also be blown into the upper part of the kitchen waste 3. Drying can be promoted by uniformly contacting the airflow with the kitchen waste 3.

In addition, as shown in FIG. 10, a heat pipe or a heat conductor 39 can be provided upright from the airflow blowing structure 10 of the processing container 4. According to this configuration, the heat of the air current can be substantially uniformly transmitted to the garbage 3 in the processing container 4 in the vertical direction, and drying of the garbage 3 can be promoted.

Is the same as Therefore, the same portions as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and the description thereof will be omitted.
