Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for treating decompressed garbage which is dried under reduced pressure by suction and exhaust from atmospheric pressure, for example, to treat garbage generated in a kitchen called garbage. It is used for dry processing.

[0002]

2. Description of the Related Art Such a reduced-pressure food waste processing apparatus is disclosed in, for example, Japanese Patent Application Laid-Open No. 08-49969 and Japanese Patent Application Laid-Open No. 08-19.
It is already known from Japanese Patent No. 3784. Especially, in the latter publication, a disposer that simply crushes raw garbage and discharges it into the sewage has a significantly high BOD of the treated wastewater, which imposes a heavy burden on the sewage treatment. The raw garbage dehydrator that crushes, dehydrates and collects the raw garbage does not undergo any other treatment such as drying on the collected raw garbage, so it easily rots and causes bad odors and causes pests and pathogens. . A food waste treatment device that completely incinerates or drys food waste using heating means such as microwaves and heaters generates organic gas, that is, odor, in addition to water vapor, but it is necessary to deodorize and purify this odor component. It is extremely difficult, and inevitably causes odor problems during processing. And, especially in the incineration process, the equipment needs to withstand high temperature, and in the drying process, the treatment efficiency is low unless the temperature is set to a high temperature of at least 100 ° C. The point is that the raw garbage, which has been raised and modified, becomes very odorous after drying. Are disclosed respectively.

Further, this publication addresses the above problems and
A corresponding technique is disclosed by providing a storage unit for storing raw garbage, a decompression unit for decompressing the inside of the storage unit, and a heating unit for heating the raw garbage in the storage unit. According to this, since the garbage is heated while being decompressed, the moisture of the garbage can be efficiently evaporated at a low temperature, and the garbage can be dried in a short time, thereby reducing the problem of odor and the problem of heat. However, the time required for processing will be shortened.

[0004]

However, the inventors of the present invention have conducted various use experiments on the conventional apparatus as described above in consideration of the treatment in a dense area of a house or a building or in a home. . As a result, the following was revealed. In the conventional garbage processing device described above, since the drying processing container that stores the garbage and heats it from above while decompressing it and dries the garbage is vertically long, the closer it is to the full volume, the total volume of the accumulation depth of the garbage. Ratio is high. For this reason, it is difficult for radiant heat to reach the lower part due to an increase in distance and an increase in the amount of raw garbage passing through, and a large difference occurs in the degree of heating and the degree of temperature rise.
At the same time, even if the boiling point is reduced by depressurization, the ratio of the open area into the drying treatment container to the total volume of raw garbage is small, so the residence time of steam generated by the raw garbage itself is increased. I will end up.

These problems become more remarkable as the amount of raw garbage treated increases, and propagation of various bacteria in the half-baked heating portion due to uneven treatment, decay of raw garbage, generation of odor due to these, and generation of steam. This causes the bacteria to propagate and the garbage to rot due to being discharged after being in contact with the garbage for a long time, and to cause an odor to be generated. These can be dealt with to some extent by a type provided with a stirring means for crushing or stirring raw garbage as in the above-mentioned conventional example. However, it is difficult to efficiently and reliably replace the top and bottom of the garbage in the vertical drying treatment container, and the problem cannot be solved, and the processing time is inevitably long to eliminate the unevenness of the drying treatment for all the garbage. turn into.

In the above-mentioned conventional example, moisture in the exhaust gas including the sucked and discharged vapor is condensed and separated, and the condensed water is stored in the drain tank, which is generated from raw garbage during the exhaust to the outside. Since it is not mixed with water, the smell of steam generated from garbage does not occur. However, there is a separate effort to drain the condensed water to the sewage, and the condensed water at this stage still smells. According to a vaporization experiment conducted on the drain water separated from the exhaust gas by the present inventors, the drain water is vaporized by heating even though the evaporated water is condensed. Even in the case of pseudo vaporization in which fine atomization is performed by sound waves, non-vaporized foreign matter remains as a residue, and the vaporized and diverged air flow does not smell. here,
It can be said that the non-vaporized foreign matter contains a source of odor, and it is easy to cause the condensed water containing the odor to flow into the sewage as it is in the summer or high temperature areas where the odor is likely to occur.

From the above, in consideration of the treatment in a densely packed area of a private house or in a household, the propagation and decay of various bacteria in raw garbage, the further prevention of odor, the improvement of usability, the further reduction of the equipment cost, the further reduction of the running cost. Reduction etc. is desired.

An object of the present invention is to provide a method and apparatus for treating garbage that can solve at least one of such problems.

[0009]

In order to achieve the above object, a decompression raw garbage processing apparatus of the present invention is a drying treatment container having an agitating means inside, and a suction for depressurizing the inside of the drying treatment container. A decompression means, a condensing means for condensing the water in the exhaust during suction and exhaust between the drying processing container and the suction decompression means to separate it from the exhaust, and a storage means for storing the condensed water in the condensing means The main feature of the present invention is that the condensing means uses a suction / exhaust passage that is provided around the outside of the drying processing container.

In such a construction, by placing the raw garbage in the drying processing space in a suction and decompression environment, the boiling point of the water of the raw garbage is lowered so that the raw garbage can be efficiently dried at room temperature or low temperature, while the raw garbage is stirred. By reliably and vigorously exchanging the garbage, the raw garbage is directly and uniformly exposed to the decompressed environment to promote evaporation of water and diffusion to the upper part of the drying treatment space. As a result, the raw garbage can be dried at room temperature or at a low temperature more uniformly, efficiently, and in a shorter time than without stirring, and uneven processing or generated steam is caused by long stay in the raw garbage. Propagation and spoilage of various bacteria, and odor emission due to this can be reduced more than when not stirring. In addition, the device required for this does not become complicated and does not cause an increase in device cost. As a result, it is possible to easily prevent the moisture generated by the steam generated evenly for drying the garbage from being mixed in the exhaust gas as it is and producing an odor, and the separated condensed water is stored in the storage means. Since the water is stored, it is possible to prevent the condensed water from being inadvertently drained and causing problems such as odor.
In particular, since the condensing means uses a suction / exhaust passage that is piped around the outside of the drying processing container, it is sufficient to exhaust the moisture in the exhaust to the outside in a wide outer surrounding area along the outer surface of the drying processing container. The pipe length required for condensation can be obtained without increasing the bulkiness, and the device can be downsized and the cost can be reduced without deteriorating the performance of the device.

On the other hand, according to the method for treating decompressed garbage of the present invention, the garbage is placed in a suction decompressed environment in a drying treatment space having a depth dimension which is substantially equal to or less than the maximum dimension between the peripheral walls and stirred. The main feature is to perform a process of drying raw garbage.

In such a structure, the raw garbage in the drying treatment space is placed in a suction and decompression environment to lower the boiling point of the moisture of the raw garbage so that the raw dust can be efficiently dried at room temperature or low temperature, while the drying treatment space is being dried. Is approximately the same as or less than the maximum dimension between the peripheral walls, so that the ratio of the area open upward in the drying treatment space to the total volume of the garbage collected and agitated in the drying treatment space Is larger than the conventional one, and the ratio of the deposition depth is smaller than the conventional one, the vapor generated from the raw garbage easily diverges into the drying processing space without disturbing the raw garbage itself, and the vertical movement of the raw garbage by stirring The solid waste is directly and uniformly exposed to the decompression environment to promote the evaporation of water and the diffusion to the upper part of the drying treatment space.
As a result, it is possible to achieve uniform, efficient, and short-time drying of raw garbage at room temperature or at a low temperature.
It is possible to reduce the proliferation and spoilage of various bacteria due to the unevenness of the treatment and the generated steam staying in the garbage for a long time, and the emission of the odor due to this, more than ever before. In addition, the device required for this does not become complicated and does not cause an increase in device cost.

As an apparatus for achieving such a method,
A drying treatment container having a depth dimension substantially equal to or less than the maximum dimension between the peripheral walls and having a stirring means inside, and suction decompression means for suction decompressing the inside of the drying treatment container,
It is sufficient to use the internal space of the drying processing container as the drying processing space of the above method. However, a condensing unit that condenses the water in the exhaust gas during suction and exhaust between the drying processing container and the suction depressurizing unit to separate it from the exhaust gas, and a storage unit that stores the condensed water in the condensing unit. It is also possible to provide a device characterized by being provided. As a result, it is possible to easily prevent the moisture generated by the steam generated evenly for drying the garbage from being mixed in the exhaust gas as it is and producing an odor, and the separated condensed water is stored in the storage means. Since the water is stored, it is possible to prevent the condensed water from being inadvertently drained and causing problems such as odor.

By the way, a moisture absorbing member may be provided in the exhaust passage after the condensing means including the exhaust port of the suction decompression means. This makes it possible to easily separate the water contained in the exhaust gas at low cost by utilizing the hygroscopic effect of the hygroscopic member, or to separate and retain the separated water. When the moisture absorption is near saturation, take out the moisture absorption member and replace it, or
The absorbed water may be squeezed out or dried and then reused.

In addition to the above method, it is possible to radiatively heat the garbage from above.

In such a structure, the heat source of the upper shell is increased because the ratio of the area open upward in the drying processing space to the total volume of the garbage collected and stirred in the drying processing space is larger than in the conventional case. The ratio of the heating area and the area directly receiving the radiant heat of garbage increases. At the same time, since the ratio of the depth of accumulation of raw garbage to the total volume is smaller than in the conventional case, the distance from the heating source is shorter and the raw garbage itself is less likely to be disturbed. These results,
Radiant heat is more likely to reach all accumulated garbage than before, and the above-mentioned upper and lower agitation efficiency is higher than before so that the chances of radiation heat reaching each garbage evenly increase evenly. This makes it possible to achieve low-temperature drying more evenly and in a shorter time,
While further suppressing the generation of odor, the running cost when using a heating source is reduced as compared with the conventional case.

In addition to performing the radiant heating, the garbage is also heated from below by a heat absorbing member located in the bottom portion of the drying processing space and absorbing the heat from the above heating to raise the temperature. You can

In such a structure, the heat absorbing member absorbs radiant heat reaching the bottom of the drying treatment space and rises to a higher temperature than raw garbage due to the property that the heat absorbing member has a higher heat absorption rate and / or heat storage property than raw garbage. To do. For this reason, the raw garbage in the drying treatment space is also heated from the lower side to supplement the heating of the raw garbage at the bottom where the radiant heat from the top is hard to reach, improving the heating efficiency of the whole raw garbage and making it even and even shorter. Drying in time can be achieved.

In addition to performing the processing for drying the raw garbage by each of the above methods, the water in the exhaust gas during the suction and exhaust for the suction and pressure reduction from the drying processing space is condensed and separated, and the separated condensed water is separated. It is also possible to perform deodorizing and purifying exhaust that is vaporized or pseudo vaporized at a suitable time to leave the non-vaporized foreign matter and diffuse to the outside.

In such a structure, the odorous component contained in the vapor when the raw garbage is dried is removed by separating the water contained in the exhaust gas which is sucked and exhausted for the purpose of reducing the suction pressure as in the conventional case. In addition to exhausting and eliminating the influence of odor on the surroundings, the condensed water condensed for the separation is vaporized or pseudo-vaporized in a timely manner to be emitted to the outside.
You can save the trouble of flowing condensed water to sewage. In particular,
Even if there is an odorous component in the condensed water, the non-vaporized foreign matter including the odorous component remains as a residue due to the vaporization or pseudo-vaporization and remains as a residue. It is possible to prevent the influence of odor on the surroundings. This may be done continuously, or as needed, or whenever the condensed water reaches a predetermined amount, or periodically, such as timely.
The remaining non-vaporized foreign matter is a granular material, is easy to handle, and has a very small amount compared to the condensed water, so there is no problem in disposing it as general waste, and there is no odor when the condensed water is directly discharged into the sewage. The problem goes away.

As an apparatus for achieving such a method,
A drying processing container having an agitating means inside, a suction depressurizing means for sucking and depressurizing the inside of the drying processing container, and condensing water in exhaust gas during suction and exhaust between the drying processing container and the suction depressurizing means. It suffices to include a condensing means for separating from the exhaust gas, and a deodorizing and purifying exhaust means for timely vaporizing or pseudo-vaporizing the condensed water in the condensing means to leave the non-vaporized foreign matter and diffuse it to the outside.

In addition to this, it is possible to provide a supply means for supplying condensed water from the condensing means to the deodorizing / purifying / exhausting means in a timely manner.

With such a construction, the deodorizing / purifying exhaust means only needs to work when the condensed water is supplied, and the deodorizing / purifying exhaust can be achieved without excess or deficiency while minimizing the running cost.

It is easy to control that the timely supply is at regular intervals, and it is particularly suitable when the processing is stable.

Further, the condensing means in each of the above-mentioned devices may be one utilizing a suction / exhaust passage piped around the outside of the drying processing container.

With such a structure, in a wide outer peripheral region along the outer surface of the drying treatment container, the pipe length required to sufficiently condense the water in the exhaust gas to the outside can be obtained without making it bulky. Thus, it is possible to reduce the size and cost without lowering the performance of the device.

Further, in each of the above devices, a far infrared heater may be provided on the lid of the drying processing container.

With such a construction, when the garbage is placed in a reduced pressure environment in the drying treatment container and dried with stirring,
A far-infrared heater, which is a heating source, is supported without a special supporting member by using a lid that closes the drying processing space formed by the drying processing container at the upper part, and, in addition, radiation heating is performed from above, but in a depressurized state. The far-infrared rays, which have particularly excellent radiation characteristics and heating characteristics, make it possible to efficiently heat food waste and accelerate drying. Also,
When the drying treatment container has a depth dimension that is approximately equal to or less than the maximum dimension between the peripheral walls, in particular, in addition to the advantages already described by the shallow and wide drying treatment space, Both the ratio of the heating area of the far-infrared heater to the volume and the area of the area directly receiving the radiant heat of garbage become larger than before, and the radiant energy of far-infrared radiation and the disadvantage that heating energy is inversely proportional to the square of the distance are mitigated. Therefore, the heating efficiency is further improved and the drying can be accelerated, which leads to further reduction of odor and further reduction of running cost.

Further, a heat absorbing member for absorbing heat from the far-infrared heater to raise the temperature and heat the garbage from below can be provided at the bottom of the drying treatment container.

With such a structure, the heating from below in the drying processing space using the heat absorbing member can effectively be achieved by effectively functioning as the heat source of the far infrared heater.

In each of the above devices, a sensor is provided in the suction / exhaust path for detecting at least one of information relating to control of temperature, humidity, etc., including pressure for controlling processing operation. can do.

Usually, in the drying processing container or the drying processing space where the garbage is actually processed, the pressure, temperature, humidity, etc. related to the control are not constant depending on the place and the time. Therefore, if these pieces of information are detected in the garbage processing area, information that is far from the actual processing environment or processing state may be obtained. However, in the suction / exhaust path, the differences in pressure, temperature, and humidity due to the difference in the processing environment of each part in the drying processing space in the drying processing container and the difference in the processing state appear relatively stably. Therefore, by detecting necessary information related to control in this suction / exhaust path as in the above-mentioned configuration, the processing environment and the processing environment at that time can be changed from the relationship with the actual processing environment and processing state that have been verified in advance. The processing status can be determined without error,
By properly controlling the processing environment and processing state, it is possible to always stably dry food waste according to the setting.

Further objects and features of the present invention will become apparent from the following detailed description and drawings. The features of the present invention can be used alone or in combination in various combinations as much as possible.

[0034]

Embodiments of the method and apparatus for treating decompressed raw garbage of the present invention will be described below in detail with reference to the drawings for the understanding of the present invention.

In the simplest way, the reduced-pressure raw garbage treatment method of this embodiment is performed in the drying treatment space S with a depth dimension H that is substantially equal to or less than the maximum dimension D between the peripheral walls with reference to FIG. Place Garbage 1 in a suction depressurized environment and agitate Garbage 1
Is dried.

Thus, the raw garbage 1 in the drying processing space S
By placing in a suction and decompression environment, it is possible to lower the boiling point of water, which is said to be 80 to 90% of the garbage 1. The boiling point decreases as the vacuum pressure approaches vacuum, and becomes the lowest in vacuum. However, if the degree of vacuum becomes high, it will be costly to decompress and seal, and the drying processing container 2 forming the drying processing space S will be described.
It becomes a pressure device and becomes large and expensive. In any case, since the boiling point is lowered in a reduced pressure environment, it can be efficiently dried at room temperature without heating or at low temperature even if heated.

Moreover, while the garbage 1 is placed in such a reduced pressure environment, the depth dimension H of the drying treatment space S is substantially the same as or less than the maximum dimension D between the peripheral walls. The ratio A / V of the area A opened upward in the drying processing space S to the total volume V of the raw garbage 1 group stored and stirred in the chamber is larger than the conventional one, and the ratio H / V of the deposition depth is larger than the conventional one. As the steam 3 generated from the raw garbage 1 easily diffuses into the drying processing space S without disturbing the raw garbage 1 itself, and the upper and lower sides of the raw garbage 1 can be reliably and actively switched by stirring. The individual garbage 1 is directly and evenly exposed to the reduced pressure environment to promote the evaporation of water and the diffusion to the upper part of the drying processing space S. As a result,
Dry garbage 1 at room temperature or low temperature more uniformly than before,
It can be achieved efficiently and in a short time, and the proliferation and spoilage of various bacteria caused by the uneven treatment and the generated steam 3 staying in the garbage 1 for a long time, and the emission of odor due to this, can be reduced more than ever before. You can In addition, the device required for this does not become complicated and does not cause an increase in device cost.

As an apparatus for achieving such a method,
As shown in FIGS. 1 to 6, the maximum dimension D between the peripheral walls (diameter in a circular container as in the example shown in the figure) has a depth dimension H that is substantially equal to or smaller than that, and the stirring means 10 is provided inside. It is sufficient that the drying processing container 2 and the suction depressurizing means 4 for sucking and depressurizing the inside of the drying processing container 2 are provided, and that the internal space of the drying processing container 2 is used as the drying processing space of the above method.

However, as in the embodiment shown in the figure, there is a condensing means 5 for condensing the water in the exhaust gas during the suction and evacuation between the drying processing container 2 and the suction decompression means 4 to separate it from the exhaust gas 8. It is preferable that the storage means 7 for storing the condensed water 6 in the condensation means 5 is provided. As a result, it is possible to easily prevent the moisture generated by the steam 3 generated evenly and efficiently for drying the garbage from being mixed into the exhaust gas as it is and giving off an odor, and the separated condensed water 6 is stored. Since it is stored by the means 7, it can be prevented from being accidentally discharged as it is and the problem such as the odor caused by the condensed water 6 does not occur.

Instead of the storage means 7, or
At the same time, a moisture absorbing member (not shown) may be provided in the exhaust passage 11 after the condenser 5 including the exhaust port 9 of the suction pressure reducing unit 4. By doing so, it is possible to easily separate the water contained in the exhaust gas 8 at a low cost by using the hygroscopic action of the hygroscopic member, or to separate and retain the water. Zeolite (trade name) is used as the moisture absorbing member. When the moisture absorption is close to the saturated state, the moisture absorbing member may be taken out and replaced, or the absorbed moisture may be squeezed out or dried and used again. Exhaust 8 of condensed water 6 by the moisture absorbing member
The separation may be performed by passing the exhaust gas 8 through the moisture absorbing member, but there is a disadvantage that the ventilation resistance increases as the separating function and the amount of water absorption increase. Therefore, whether the exhaust gas 8 collides with the moisture absorption member to capture and absorb the condensed water 6 or the exhaust gas 8 collides with the wall of the device or the baffle plate and the separated condensed water 6 is absorbed and retained by the moisture absorption member. And exhaust 8
Is preferably exhausted from the exhaust port 9.

In addition to the method and / or apparatus in each case described above, it is preferable that the garbage 1 is radiantly heated from above by a suitable heat source 12 as in the embodiment shown in the drawing. As a result, the ratio A / V of the area A open upward in the drying processing space S to the total volume V of the raw garbage 1 group stored in the drying processing space S and stirred by the stirring means 10 is larger than the conventional one. As a result, the ratio HA / V of the heating area of the heat source 12 and the ratio A / V of the area where the raw garbage 1 directly receives the radiant heat increase, and at the same time, the ratio of the deposition depth H1 of the raw garbage 1 to the total volume V increases. As H1 / V becomes smaller than in the conventional case, the distance from the heat source 12 is short, and it is less likely to be disturbed by the garbage 1 itself. As a result, the radiant heat 13 from the heat source 12 is more likely to reach the accumulated raw garbage 1 than ever, and the stirring efficiency of the raw garbage 1 above and below is higher than the conventional one. Due to the synergistic effect that the radiant heat 13 directly reaches the heat exchanger 12 evenly, the drying at low temperature can be achieved more uniformly and in a shorter time, and when the heat source 12 is used while further suppressing the generation of odor. Running costs are lower than before.

In addition to performing such radiant heating, in the embodiment shown in the figure, a stirring means 10 is located in the bottom of the drying processing space S to absorb the heat from above and raise the temperature. The shared heat absorbing member 15 heats the garbage 1 from below.

The heat absorbing member 15 is effective if it absorbs heat and / or accumulates heat in excess of the raw dust 1, because it raises the temperature higher than that of the raw dust 1. If it depends on the material itself, a metal member may be used. It is suitable. If the surface is treated black, the endothermic effect is enhanced. However, the present invention is not limited to this, and members made of other materials and other methods can be adopted. Since the larger the area facing the heat source is, the more effective it is for absorbing heat, the bottom wall of the drying treatment container 2, or in addition to this, the peripheral wall itself or a peripheral wall thereof may be used. When the heat absorbing member 15 sharing the agitating means 10 is also used in combination with this, or independently, the heat absorbing member 15 is swirled in the drying treatment container 2 to agitate the raw garbage 1 so that the heat absorbing member 15 moves by a constant motion. Even if it is only partially, it is easy to uniformly apply the radiant heating from below to the whole garbage 1.

In any case, when the heat absorbing member 15 is provided, the heat source 12 that reaches the bottom of the drying processing space S due to the property that the heat absorption rate and / or the heat storage property is higher than that of the garbage.
By absorbing the radiant heat 13 from the above to raise the temperature higher than that of the raw garbage, the raw garbage 1 in the drying processing space S is also heated from below, and the radiant heat 1 from above does not easily reach the raw garbage 1 at the bottom. Since the above heating is supplemented, it is possible to improve the heating efficiency of the whole raw garbage 1 and achieve even drying in a shorter time. Further, the heating from below by the heat absorbing member 15 is performed by directly contacting with the garbage 1, and is also performed by the radiant heat 13 a from the heat absorbing member 15.

In order to perform the processing for drying the raw garbage 1 by each of the above-described methods or apparatuses, in the embodiment shown in the figure, the water content in the exhaust 8 which is in the middle of suction and exhaust due to the suction pressure reduction from the drying processing space S is removed. The condensed water 6 is condensed and separated, and the separated condensed water 6 is vaporized or pseudo-vaporized in a timely manner to leave the non-vaporized foreign matter 16 as schematically shown in FIG. I have to. As described above, vaporization is evaporation by heating, and pseudo-vaporization is atomization into a fine mist by ultrasonic waves. This is a characteristic of concentration and vibration separation for leaving non-vaporized foreign matter 16 containing odorous components as a residue. It is suitable because it can exhibit.

As a result, by separating the water contained in the exhaust gas 8 which is sucked and exhausted for suction decompression as in the conventional case, the odorous component contained in the steam 3 when the raw garbage 1 is dried is removed. In addition to exhausting and eliminating the influence of odor on the surroundings, the condensed water 6 condensed for separation from the exhaust 8 is vaporized or pseudo vaporized in a timely manner, and then is emitted to the outside as purified air 8a. By doing so, it is possible to save the trouble of flowing the condensed water 6 to sewage or the like.
In particular, even if there is an odorous component in the condensed water 6, the non-vaporized foreign matter 16 contains the odorous component and remains as a residue due to the vaporization or pseudo-vaporization, so that the vaporized divergence of the condensed water 6 eliminates the odorous component and exhausts it to the outside. The purified air 8a that has achieved so-called deodorizing purification is exhausted, and the influence of odors on the surroundings can be further prevented. This may be performed continuously, as needed, or whenever the condensed water 6 reaches a predetermined amount, or periodically, at any time, and the remaining non-vaporized foreign matter 16 is a granular material and is easy to handle. Moreover, since it is a very small amount compared to the condensed water 6, there is no problem of discarding it as general waste, and the problem such as the odor when flowing the condensed water 6 as it is to the sewage is solved.

In order to achieve this, in the apparatus of the embodiment shown in the figure, in addition to the drying processing container 2 having the stirring means 10 inside, the suction depressurizing means 4 and the condensing means 5,
The deodorizing / purifying / exhausting means 17 as shown in FIGS. 1, 3 and 4 is provided for vaporizing or pseudo-vaporizing the condensed water 6 in the condensing means 5 in a timely manner and leaving the non-vaporized foreign matter 16 to be diffused to the outside. The deodorizing purification discarding means 17 shown in the figure heats the condensed water 6 received as shown in FIG.
In order to perform this in a timely manner, a supply means 22 for supplying the condensed water 6 in the condensing means 5 to the deodorizing / purifying and exhausting means 17 in a timely manner is provided.

Specifically, the storage means 7 and the deodorizing / purifying / exhausting means 17 are connected by a solenoid valve 23, and whenever necessary,
The electromagnetic valve 23 is opened and the condensed water 6 stored in the storage means 7 is poured into the deodorizing / purifying / exhausting means 17 and heated by the heater 21 to be evaporated and diverged. As a result, the heater 21 needs to work only when the condensed water 6 is vaporized and diffused, and it is possible to achieve deodorizing and purifying exhaust gas that is sufficient in amount while minimizing the running cost. However, it is easy to control that the timely supply is at regular intervals, and it is particularly suitable when the process is stable. The deodorizing / purifying / exhausting means 17 may be provided with a deodorizing material 71 such as activated carbon in its vaporization treatment area or the like as shown in FIG. 3, for example, to enhance the deodorizing effect. The deodorizing material 71 may be a deodorizing catalyst. In the case of a catalyst, the deodorizing efficiency of the exhaust gas 8 containing water decreases, so that it is preferable to install the condensed water 6 in a path through which the condensed water 6 is vaporized and discharged as purified air 8a.

In the embodiment shown in the figure, the condensing means 5 also uses a suction / exhaust passage 11 which is provided around the outside of the drying processing container 2. Thereby, the drying processing container 2
In a wide outer area along the outer surface of the, the pipe length required to sufficiently condense the water in the exhaust 8 to the outside can be obtained without bulking, and the device can be downsized without deterioration in performance. The cost can be reduced. In the illustrated case, the suction / exhaust passage 11 is formed into a coil shape and descends from the drying processing container 2 side to the storage means 7 side with a gentle inclination. As a result, a pipe having a thinness and length suitable for exhausting air for suction and decompression necessary for the drying processing container 2 and cooling from the outside for condensation is achieved, and the exhaust gas 8 is exhausted by the cooling from the outside. When the water content is condensed during the exhaust, the water is smoothly flowed to the storage means 7 side while being transmitted along the inner wall of the suction / exhaust passage 11 by the inclination of the pipe and the pushing and movement by the exhaust flow toward the exhaust port 9. The storage means 7 can be easily reached. However, suction and exhaust path 1
The form of the one pipe can be freely selected.

Further, in the embodiment shown in the drawing, the heat source 12 for radiantly heating the garbage 1 is a far-infrared heater provided in the lid 25 which opens and closes the upper opening of the drying processing container 2. A heat source 12 which is an infrared heater is utilized by using a lid 25 that closes a drying processing space S formed by the drying processing container 2 in order to dry the garbage 1 in the drying processing container 2 in a reduced pressure environment while stirring. Can be supported without a special support member. Moreover, since the radiant heating is performed from above, the raw dust 1 can be efficiently heated and the drying can be promoted by the irradiation of far infrared rays having excellent radiation characteristics and heating characteristics in a reduced pressure state. In particular, the drying treatment space 2 is shallow and wide because the drying treatment container 2 has the depth dimension H that is substantially equal to or less than the maximum dimension D between the peripheral walls as described above, and the advantages described above due to the fact that the drying treatment space S is shallow and wide. In addition, the heating area ratio HA / V of the heat source 12 as the far-infrared heater to the total volume V of raw garbage and the ratio A / V of the area directly receiving heat of the raw garbage 1 are both larger than the conventional one, and far infrared rays Since the radiant energy and heating energy of the above are alleviated to the disadvantage of being inversely proportional to the square of the distance, the heating efficiency can be further improved and the drying can be speeded up, leading to further reduction of odor and further reduction of running cost. In order to increase the heating area ratio HA / V, the heat source 12 is preferably provided at the full opening of the drying processing container 2 regardless of whether it is a far-infrared heater or not, and the surface heater spreads in such a range. Are particularly preferable.

If the heat source 12 is a far infrared heater, the heat absorbing member 15 is naturally selected to be suitable for absorbing far infrared rays and raising the temperature. It works well and can be achieved more advantageously than with other types of heaters.

Further, in order to control various operations required for the drying treatment of the raw garbage 1 as described above, the apparatus of the embodiment shown in the figure has a control means 31 using a microcomputer as shown in FIG. I have it. The control means 31 is determined in advance in correspondence with the initial setting information, the setting information input from the operation panel 32 shown in FIG. 1, and the detection information such as the pressure, temperature, and humidity for the drying process in the reduced pressure environment. The operation control is performed according to the control program described above, and the drying process of the garbage 1 accompanied by stirring and heating in the above-described reduced pressure environment is performed. Further, the control means 31 displays a control state, various information and instructions on the operation panel 32 or the like as necessary, or gives a notice, a warning or an instruction by a buzzer sound or a pseudo voice.

Here, in order to obtain information relating to the control of the processing environment and the processing state such as pressure, temperature, and humidity, the drying processing container 2 and the drying processing space where the raw garbage 1 is actually processed are obtained. If the detection is performed in S, the information is not constant depending on the place and the time. Therefore, there is a case where information that is greatly deviated from the actual processing environment or processing state is obtained.
On the other hand, in the suction / exhaust passage 11 forming part or the whole of the suction / exhaust path, the drying processing space S in the drying processing container 2 is formed.
The differences in pressure, temperature, and humidity due to differences in the processing environment of each part and differences in the processing state appear relatively stably as an integrated one. Therefore, in the embodiment shown in the drawing, as shown in FIG. 4, a pressure sensor 41, a temperature sensor 42, and a humidity sensor 43 are provided in the middle of the suction / exhaust passage 11 to detect necessary information related to the control. is there. Thereby, the pressure sensor 41, the temperature sensor 42, and the humidity sensor 43
Based on the relationship between the information detected by and the actual processing environment and processing state verified in advance, the processing environment and processing state at that time can be determined without error, and the correct control of the processing environment and processing state can be performed. The garbage can always be dried stably according to the setting.

For example, the pressure information is used to control the operation of the suction pressure reducing means 4, the temperature information is used to control the driving of the heat source 12, and the humidity information is used to determine the progress and end of drying of the garbage 1. Used. However, the same applies to the detection of other necessary information, and even if only the suction / exhaust passage 11 detects at least one of the pressure, the temperature, and the humidity, the above-mentioned characteristics can be obtained in the detected information. To be

A more specific description will be given below. The drying treatment container 2 is made of metal and can share the heat absorbing member 15 for the radiant heat from the heat source 12, as shown in FIGS.
As shown in FIG. 5, the outer case 45 is fitted into the opening at the substantially central portion of the top plate 46 from above, and the outward flange portion is placed and fixed on and supported by the opening edge via the seal packing 47. The outer circumference of the drying treatment container 2 is covered with a heat insulating case 44, and the outer side thereof is covered with a metal enclosure wall 48 mounted and supported on the lower surface of the top plate 46, and the space between the two is condensed.
9 is formed. This drying processing container 2 is a heat insulating wall 44
The suction / exhaust passage 11 is piped in a condensing chamber 49 which is separated by, and the condensing means 5 is constituted by a fan 51 that cools this in the condensing chamber 49. The fan 51 is driven by a dedicated motor 72, but it may be shared with the motor 56 of the stirring means 10, and both means are driven simultaneously in most cases, which is suitable for simplification of structure and control. . The enclosure wall 48 integrally fixes the attachment portion 52 of the fan 51, and also the intake hole 4 for cooling.
8a and an opening 48b through which the drive shaft 53 of the stirring means 10 penetrates, or a dedicated exhaust port, and a fan 51 that blows air to the condensing means 5, and the like. To the respective parts of the piping of the suction / exhaust passage 11 in the condensing means 5 so that the condensing efficiency can be improved. Of course, the condensing means 5 can be configured as a heat sink with fins for condensing water, or can be condensed by contacting with a separately formed heat sink. Especially when a heat sink is provided at the outlet from the drying processing space S to the suction / exhaust passage 11, early condensation can be achieved, so that the condensation efficiency is improved. However, a heat sink may be provided at the connection portion of the suction / exhaust passage 11 to the storage means 7 so as to achieve final condensation so that the exhaust gas 8 does not contain water. The separation of the condensed water 6 from the exhaust gas 8 can be performed by centrifugal separation on the exhaust path without depending on the collision or the moisture absorbing member. Further, it may be mechanically separated by a vacuum pump, a suction pump, a fan or the like which is the suction pressure reducing means 4. When the condensation efficiency is increased by a heat sink or the like, the length of the suction / exhaust passage 11 for condensing can be shortened, which is suitable for enhancing the suction / exhaust efficiency.

The drive shaft 53 is supported by a bearing 54 provided at the center of the bottom of the drying processing container 2, and a stirring blade as the stirring means 10 is attached to the upper end. The stirrer 10 has a function of crushing the raw garbage 1 in addition to stirring the raw garbage 1, so that the evaporation of the water content of the raw garbage 1 can be further accelerated and the drying efficiency can be further improved. ing. The bearing 54 is used for the dry processing container 2 and the drive shaft 5.
A seal (not shown) is provided between the drying treatment container 2 and
It is designed so that no leak occurs when the pressure is reduced to a predetermined degree of vacuum. A passive pulley 55 is provided at the lower end of the drive shaft 53, and the motor 5 installed at the center of the bottom of the outer case 45
The rotation of No. 6 is decelerated and transmitted via the reduction mechanism 57. As a result, the crushing of the raw garbage 1 proceeds early, the water content becomes excessive, evaporation is delayed, and odor is generated.
It prevents various bacteria from multiplying and spoiling.

The lid 25 is supported by a pair of bearings 58 provided on both sides along one side of the top plate 46 of the outer case 45 as shown in FIGS. The seal packing 61 provided on the inner lid 60 fixed to the inner side of the upper plate 46 seals between the outer periphery of the opening in which the drying treatment container 2 of the top plate 46 is fitted and supported, and again, the reduced pressure state required for the drying treatment container 2 is maintained. I try to keep it. A cover 63 that forms a suction / exhaust chamber 62 between the inner lid 60 and the inner lid 60 is attached to the inner lid 60, and the air in the drying processing space S is sucked through a large number of suction holes 64 arranged on the outer periphery of the cover 63. It is designed to be evacuated by suction and exhausted. To this end, the side of the suction / exhaust passage 11 forming the condensing means 5 on the side of the drying processing container 2 extends in the tangential direction at one end along the peripheral wall of the outer casing 45 having a rectangular cross section as shown in FIG. As shown in FIG. 5, it rises to a position just below the lid 25, passes from the rising position between the lid 25 and the inner lid 60, and reaches the central portion of the suction / exhaust chamber 62 as shown in FIGS. It is connected to the chamber 62. As a result, the suction and depressurization action of the suction and depressurization means 4 is performed by the suction and exhaust passage 11 forming the condensing means 5 on the way and the suction and exhaust chamber 6.
2. Through the suction holes 64, the drying processing space S in the drying processing container 2 extends almost evenly. The heat source 12 is provided in such a size that it extends right inside the portion where the suction holes 64 are arranged to enhance the heating efficiency. However, the installation area of the heat source 12 can be enlarged by making the arrangement position of the suction holes 64 complicated with the arrangement position of the heat source 12.

The suction decompression means 4, the storage means 7, the deodorizing / purifying and exhausting means 17, and the suction depressurizing means 4> the storing means 7> the deodorizing / purifying / exhausting means 17 are in such a relation that the installation height is satisfied. 6 are sequentially moved and processed. Further, the storage means 7 and the deodorizing / purifying / exhausting means 17 are installed in a lower space formed in the plane arrangement of the drying processing container 2 in the outer case 45.

The suction hole 64 may be provided in the drive shaft 53 to suck and decompress the inside of the drying processing space S through the suction / exhaust passage 11 formed in the drive shaft 53. In this case, the suction holes 64 can efficiently suck and exhaust the generated vapor if they are in the accumulation area of the garbage 1, but the suction holes 64 are provided with air so that the crushed fine garbage 1 does not flow out. It is necessary to provide a filter that allows only water and moisture to pass through. A semipermeable membrane is suitable for this filter, for example. However, in order to avoid this, the drive shaft 53 may be provided so as to extend to the upper part of the drying processing space S, and the suction hole 64 may be provided in this upper part.

A deodorizing catalyst 65 is provided at the connection port of the suction / exhaust passage 11 to the suction / exhaust chamber 62. This catalyst 65 is located at the back of the heat source 12 provided on the side of the cover 63 forming the suction / exhaust chamber 62 facing the drying processing space S, and though the cover 63 is provided, it is close to the heat source 12. The heat of the heat source 12 is easily received, and the odor in the exhaust gas 8 that is sufficiently heated and sucked and exhausted through the catalyst 65 can be efficiently removed. The fact that the catalyst 65 faces the heat source 12 at the central portion thereof also improves the heating efficiency, which also improves the deodorizing effect. The advantage of the facing structure in which the catalyst 65 is positioned immediately behind the heat source 12 facing the drying process space S is effective even when the heat source 12 is provided on the side surface or the bottom surface of the drying process space S. Also, the catalyst 65
Does not have to be provided in combination with a dedicated heater, the apparatus is simplified and space is saved, and the apparatus cost is reduced. In addition, it also saves electricity, which reduces running costs.

A vacuum pump is used as the suction pressure reducing means 4 in the embodiment shown in the figure, but for example, when the atmospheric pressure in the drying processing space S is 0 mmHg, -600 mmHg to-.
It only needs to be able to reduce the pressure to about 650 mmHg, and other suction pumps and suction fans can also be used. The drying treatment temperature was lowered to about 55 ° C. to 60 ° C. by the above-mentioned reduced pressure, and good drying treatment was performed. An experimental example shows -595 mmHg to -6.
Far infrared heater 500W in a decompression environment of 40 mmHg
By performing a drying process for about 2 hours using the heat source 12 of
The amount of 700 g of garbage 1 was reduced to 90 g and it was possible to sufficiently dry it without generating odor. The temperature in the drying processing space S at this time was 65 ° C. to 110 ° C., but the temperature of the product, that is, the temperature of the dried product of the garbage 1 was about 60 ° C. as a whole.
It was about. The lid 25 is provided with a pressure gauge 81 for external monitoring.

FIG. 7 shows another example of the reduced-pressure raw garbage processing apparatus. In this example, the drying treatment container 2 has a depth H of not less than the maximum dimension D between the peripheral walls of the container in comparison with the above example. Although the schematic configuration is shown only schematically, the other configurations are not particularly different from the above example, and thus common members are denoted by the same reference numerals, and duplicate description will be omitted. Compared to the previous example, the drying process container 2 tends to be elongated, so the height becomes higher by that amount, but other equipment is installed sideways or around it to make it almost the same as the flat space and more than the previous example. In addition to being able to make it low, the overall height can be made low even if the plane space becomes large. Therefore,
This is particularly advantageous when there is a height limitation.

Further, the drying processing container 2 having the stirring means 10 therein, the suction depressurizing means 4 for sucking and depressurizing the inside of the drying processing container 2, and the suction between the drying processing container 2 and the suction depressurizing means 4. Condensing means 5 for condensing the water in the exhaust gas 8 during exhausting and separating it from the exhaust gas 8 and storage means 7 for storing the condensed water 6 in the condensing means 5 are provided, and the condensing means 5 is a drying treatment container. Suction / exhaust passage 1 piped around 2
1 is used, by placing the raw garbage in the drying treatment space in a suction depressurized environment, the boiling point of the water of the raw garbage is lowered so that the raw garbage can be efficiently dried at room temperature or low temperature. The garbage can be replaced reliably and actively, and the garbage can be exposed directly to the decompression environment without any unevenness to promote the evaporation of water and the diffusion to the upper part of the drying treatment space. As a result, the raw garbage 1 can be dried at room temperature or at a low temperature more uniformly, efficiently and in a shorter time than without stirring, and uneven treatment or generated steam 3 stays in the raw garbage 1 for a long time. Propagation and spoilage of various bacteria due to the above, and emission of odor due to this can be reduced more than when not stirring. In addition, the device required for this does not become complicated and does not cause an increase in device cost.
As a result, it is possible to easily prevent the moisture generated by the steam 3 that is evenly and efficiently generated for drying the raw garbage 1 from mixing in the exhaust gas 8 as it is and giving off an odor. Since the condensed water 6 is stored by the storage means 7, it is possible to prevent the condensed water 6 from being inadvertently drained and causing a problem such as an odor. In particular, since the condensing means 5 uses the suction / exhaust passage 11 that is piped around the outside of the drying processing container 2, the moisture in the exhaust gas 8 is discharged to the outside in a wide surrounding area along the outer surface of the drying processing container 2. It is possible to obtain the pipe length required for sufficient condensation before exhausting without being bulky, and to reduce the size and cost without lowering the performance of the device.

According to the main feature of the reduced-pressure raw garbage processing apparatus of the present invention, the raw garbage in the drying treatment space is placed in a suction depressurized environment to lower the boiling point of the moisture of the raw garbage and to improve the efficiency at room temperature or low temperature. While ensuring good drying, the garbage is replaced reliably and actively by stirring, and each garbage is exposed directly and evenly to the depressurized environment to evaporate water and diffuse to the upper part of the drying treatment space. Can be urged.
As a result, the raw garbage can be dried at room temperature or at a low temperature more uniformly, efficiently, and in a shorter time than without stirring, and uneven processing or generated steam is caused by long stay in the raw garbage. Propagation and spoilage of various bacteria, and odor emission due to this can be reduced more than when not stirring. In addition, the device required for this does not become complicated and does not cause an increase in device cost. As a result, it is possible to easily prevent the moisture generated by the steam generated evenly for drying the garbage from being mixed in the exhaust gas as it is and producing an odor, and the separated condensed water is stored in the storage means. Since the water is stored, it is possible to prevent the condensed water from being inadvertently drained and causing problems such as odor. In particular, since the condensing means uses a suction / exhaust passage that is piped around the outside of the drying processing container, it is sufficient to exhaust the moisture in the exhaust to the outside in a wide outer surrounding area along the outer surface of the drying processing container. The pipe length required for condensation can be obtained without increasing the bulkiness, and the device can be downsized and the cost can be reduced without deteriorating the performance of the device.

According to the reduced-pressure raw garbage treatment method and apparatus of the present invention, the raw garbage in the drying treatment space is placed in a suction depressurized environment to lower the boiling point of the moisture of the raw garbage and efficiently dry it at room temperature or low temperature. While the drying treatment space has a depth dimension that is substantially the same as or smaller than the maximum dimension between the peripheral walls, the drying treatment space with respect to the total volume of the garbage group that is accommodated in the drying treatment space and agitated. As the ratio of the area that is opened upwards is larger than before and the ratio of the deposition depth is smaller than before, the steam generated from the garbage disperses into the drying treatment space without disturbing the garbage itself. It is easy, and ensures that the upper and lower parts of the garbage are exchanged reliably and vigorously, and each of the garbage is directly exposed to the decompression environment without any unevenness and the moisture evaporates and diffuses to the upper part of the drying processing space. Unagaseru. As a result, the garbage can be dried at room temperature or at a low temperature more uniformly, efficiently, and in a shorter time than ever before, and unevenness in the treatment and generated steam can cause miscellaneous germs to stay in the garbage for a long time. Breeding and rotting,
The emission of odor due to this can be reduced more than ever. In addition, the device required for this does not become complicated and does not cause an increase in device cost.

In particular, in this apparatus, a condensing means for condensing the moisture in the exhaust gas during suction and exhaust between the drying processing container and the suction depressurizing means and separating it from the exhaust gas, and the condensed water in this condensing means are stored. By means of the storage means which is provided, it is possible to easily prevent the moisture due to the steam generated evenly and efficiently for drying the garbage from being mixed into the exhaust gas as it is and producing an odor. Moreover, since the separated condensed water is stored by the storage means, it is possible to prevent the condensed water from being carelessly drained and causing a problem such as an odor.

Further, by providing a moisture absorbing member in the exhaust path after the condensing means including the exhaust port of the suction decompressing means, the moisture contained in the exhaust can be easily utilized at low cost by utilizing the moisture absorbing function of the moisture absorbing member. It can be separated or held separate. When the moisture absorption is close to the saturated state, the moisture absorbing member may be taken out and replaced, or the absorbed moisture may be squeezed out or dried and used again.

Further, by radiantly heating the raw garbage from above, the ratio of the area open upward in the drying processing space to the total volume of the raw garbage group contained and stirred in the drying processing space is larger than in the conventional case. The proportion of the heating area of the heat source of the upper shell and the area of the area directly receiving the radiant heat of the garbage increases accordingly. At the same time, since the ratio of the depth of accumulation of raw garbage to the total volume is smaller than in the conventional case, the distance from the heating source is shorter and the raw garbage itself is less likely to be disturbed. As a result, the accumulated radiant heat is more likely to reach the radiant heat than before, and the above-mentioned vertical stirring efficiency is higher than before, so that the radiant heat is evenly increased directly to each trash. By the synergistic effect with the above, the drying at low temperature can be achieved more evenly in a shorter time, and the running cost when using the heating source can be reduced as compared with the conventional case while further suppressing the generation of odor.

In addition to this radiant heating, raw garbage is also heated from below by a heat absorbing member located in the bottom of the drying processing space and absorbing the heat from above heating to raise the temperature. Further, the heat absorbing member absorbs the radiant heat reaching the bottom of the drying processing space and rises in temperature higher than that of the garbage due to the property that the heat absorbing member has higher heat absorption rate and / or heat storage property than that of the garbage. For this reason, the raw garbage in the drying treatment space is also heated from the lower side to supplement the heating of the raw garbage at the bottom where the radiant heat from the top is hard to reach, improving the heating efficiency of the whole raw garbage and making it even and even shorter. Drying in time can be achieved.

In each case of performing the above-mentioned processing for drying the garbage, the water in the exhaust gas during the suction and exhaust for the suction and decompression from the drying processing space is condensed and separated, and the separated condensed water is timely. By performing deodorizing purification exhaust that vaporizes or pseudo-vaporizes and leaves non-vaporized foreign matter to diffuse to the outside, by separating water contained in the exhaust that is sucked and exhausted for suction decompression as in the past, raw garbage is removed. The odorous components contained in the dry steam are removed and exhausted, and in addition to eliminating the odor effect on the surroundings, the condensed water condensed for the above separation is vaporized or pseudo-vaporized in a timely manner to the outside. Since it is diverged to, it is possible to save the trouble of flowing condensed water to sewage. In particular, even if there is an odor component in the condensed water, the non-vaporized foreign matter including the odor component remains as a residue due to the vaporization or pseudo-vaporization and remains as a residue, and the vaporized divergence of the condensed water eliminates the odor component and is exhausted outside. It becomes exhaust gas and can prevent the influence of odor on the surroundings. This may be carried out continuously, as needed, or whenever the condensed water reaches a predetermined amount, or periodically, and the remaining non-vaporized foreign matter is a granular material and is easy to handle, and Since the amount is extremely small compared to the condensed water, there is no problem by discarding it as general waste, and problems such as odor when the condensed water is directly discharged to the sewage are solved.

In particular, the apparatus is provided with a supply means for supplying condensed water from the condensing means to the deodorizing / purifying / exhausting means in a timely manner so that the deodorizing / purifying / exhausting means operates only when the condensed water is supplied. Well, it is possible to achieve a proper deodorizing / purifying exhaust gas while minimizing the running cost.

It is easy to control that the timely supply is at regular intervals, and it is particularly suitable when the processing is stable.

Further, the condensing means in each of the above-mentioned devices uses a suction / exhaust passage which is provided around the outside of the drying processing container, so that the moisture in the exhaust is removed in a wide outer peripheral region along the outer surface of the drying processing container. It is possible to obtain the piping length required for sufficient condensation before exhausting to the outside without being bulky, and to reduce the size and cost without lowering the performance of the device.

Further, in each of the above-mentioned devices, the far-infrared heater is provided on the lid of the drying treatment container, so that the garbage can be placed in a reduced pressure environment in the drying treatment container and dried while stirring. Using the lid that closes the drying process space formed by the drying process container at the top, supports the far-infrared heater, which is a heat source, without a special support member, and
Although the radiant heat is applied from above, the raw dust can be efficiently heated and the drying can be promoted by the irradiation of far infrared rays, which has particularly excellent radiation properties and heating properties in a reduced pressure state. Further, in the case where the drying treatment container has a depth dimension that is substantially equal to or less than the maximum dimension between the peripheral walls, in particular, in addition to the advantages already described by the shallow and wide drying treatment space, The ratio of the heating area of the far-infrared heater to the total volume of and both the area of the area directly receiving the radiant heat of raw garbage are larger than the conventional one.
Since the radiant energy of far infrared rays and heating energy alleviate the disadvantage of being inversely proportional to the square of the distance, heating efficiency can be further improved and drying can be speeded up, leading to further reduction of odor and further reduction of running cost.

Further, by providing a heat absorbing member for absorbing heat from the far-infrared heater to raise the temperature and heat the food waste from below at the bottom of the drying processing container, the lower side of the drying processing space using the heat absorbing member is provided. Can effectively be achieved by effectively acting on the heat source of the far infrared heater.

In each of the above devices, a sensor for detecting at least one of information relating to control of temperature, humidity, etc., including pressure for controlling processing operation, is further provided in the suction / exhaust path, Normally, in the drying processing container or the drying processing space where the garbage is actually processed, the location where the pressure, temperature, humidity, etc. related to the control are not constant depending on the time is controlled by the suction / exhaust path. By detecting the necessary information involved,
From the relationship with the actual processing environment and processing state that has been verified in advance, it is possible to accurately judge the processing environment and processing state from time to time, and the correct control of the processing environment and processing state ensures that garbage is always set according to the settings. It can be stably dried.
