BACKGROUND OF THE INVENTION
  This invention generally relates to garbage disposalIn machineMore specifically, garbage processing that treats garbage by heating and dryingIn machineRelated.
[0002]
[Prior art]
In recent years, disposal of garbage generated in restaurants has become a major social problem. As a matter of fact, most of the garbage processing at restaurants is requested by a garbage disposal contractor. At restaurants, employees put garbage generated during business into garbage bags, and when the garbage bags are full, they are taken out to the dump.
[0003]
The garbage bag used at this time has a large volume, and the accommodated garbage is heavy because it contains moisture. For this reason, the bag may be torn while the garbage bag is being carried out. In addition, the contents may flow out of the garbage bags due to operations such as crows and dogs at the dump. In such a case, an unpleasant odor is generated from the garbage bag, resulting in a very unsanitary situation.
[0004]
In order to solve such problems, garbage processing machines that process garbage using bacteria are becoming widespread. Other types of garbage processing machines include those that heat and dry garbage with hot air, and are disclosed, for example, in JP-A-6-262163 as a garbage disposal apparatus (Patent Document 1). According to the garbage processing machine of the type disclosed in Patent Document 1, by heating and drying the garbage, the volume of the garbage can be compressed and the weight can be reduced. And it becomes possible to process the dried garbage with general burning garbage.

[Problems to be solved by the invention]
In the garbage processing machine using bacteria, the bacteria are generated in the processing machine, and the garbage is decomposed by the bacteria. However, the amount of garbage that can be treated with bacteria is limited to a small amount, and it is difficult to use in restaurants where large amounts of garbage are continuously generated. For this reason, the garbage processing machine using bacteria is mainly used only for home use.
[0007]
In addition, it takes a period of several tens of days to treat garbage with bacteria. For this reason, when throwing in the next garbage, it is necessary to open the lid of the garbage processing machine which has not been processed yet. At this time, since the garbage in the processing machine is in the middle of being decomposed and decayed, a tremendous odor leaks from the inside to the outside. Such a problem due to a strange odor is also one of the reasons why garbage processing machines using bacteria are not popular in restaurants.
[0008]
Similarly, even in a garbage processing machine of the type in which the garbage is heated and dried with hot air as disclosed in Patent Document 1, it takes a long time to completely dry the garbage. When a long time is spent in the treatment, the amount of garbage treated is limited, and the garbage in the middle of drying rots and a strange odor is generated.
[0009]
Moreover, in order to improve the speed | rate which dries garbage, the method of raising the temperature which heats garbage can be considered. However, the garbage contains vegetables, etc. If the heating temperature is too high, the vegetables may burn out. In order to avoid such a situation and ensure safety, it is necessary to set the heating temperature below a certain temperature, which is the reason why the processing speed of the garbage processing machine cannot be improved.
[0010]
  Accordingly, an object of the present invention is to solve the above-described problems, and can process a large amount of garbage quickly and safely, and does not generate a bad odor.MachineIs to provide.
[0011]
[Means for Solving the Problems]
  The garbage processing machine according to the present invention is a side wall extending in the vertical direction, and defines an internal space for accommodating the garbage.Cylindrical shapeSide wallAnd a bottom surface that closes one end of the side wallA garbage storage section having internal combustion space, a stirring means for stirring the garbage, a first heating means for heating the garbage through the side wall, and an internal space. Second heating means for supplying a gas for drying the accommodated garbage and exhaust means for discharging the gas in the internal space to the outside are provided.The stirring means is a blade-like member that extends upward along the inside of the side wall from the bottom surface side and moves along the inside of the side wall. A 2nd heating means supplies gas toward the garbage in the state which dances in internal space by the stirring means.
[0012]
According to the garbage processing machine configured as described above, the garbage stored in the garbage container is dried by the stirring means, the first and second heating means, and the exhaust means. If the garbage can be completely dried, the garbage taken out from the garbage container can be treated as normal burning garbage. In addition, garbage is foodstuffs containing moisture, for example, the leftovers etc. which generate | occur | produce from a restaurant.
[0013]
The structure of the garbage processing machine for drying the garbage will be described in more detail. First, the garbage that comes into contact with the side wall of the garbage container is heated by the first heating means. Under the present circumstances, since the side wall of a garbage accommodating part extends inclining with respect to the perpendicular direction, the contact area of garbage and a side wall can be increased. Further, since the garbage in the internal space is stirred by the stirring means, the garbage heated on the side wall by the first heating means is sequentially replaced. Thereby, the heating by the 1st heating means is performed uniformly with respect to the whole garbage, and the garbage can be dried efficiently.
[0014]
Separately, gas for drying the garbage is supplied by the second heating means, and the garbage is dried. Drying by the second heating means is effectively performed on the garbage exposed to the atmosphere of the internal space inside the garbage containing portion, particularly the garbage in the state of dancing in the internal space by the stirring means. At this time, since the side wall of the garbage containing portion extends while being inclined with respect to the vertical direction, the garbage contacting the side wall can be dropped downward in the vertical direction to flutter the internal space. Thereby, the garbage can be efficiently dried by the second heating means.
[0015]
  Furthermore, the garbage is accelerated by being stirred by the stirring means. That is, the atmosphere in the internal space is heated by the first and second heating means. In addition, a gas such as steam generated from the garbage is sequentially discharged to the outside by the exhaust means. Drying of the garbage can be promoted by stirring the garbage in a high temperature atmosphere in the formed internal space.The stirring means is a blade-shaped member that moves along the inside of the side wall. For this reason, the relative movement with respect to the side wall of the garbage accommodating part of garbage can be performed reliably, and the garbage which contacts a side wall can be replaced | exchanged one after another. Thereby, heating of garbage by the 1st heating means can be accelerated | stimulated, and garbage can be dried in a shorter time.
[0016]
As described above, the garbage is dried while the agitation by the agitation means, the heating by the first heating means, the gas supply by the second heating means, and the gas discharge by the exhaust means interact with each other. To do. Thereby, garbage can be dried in a short time, and the processing capacity of a garbage processing machine can be improved significantly. In addition, since the processing of the garbage can be completed before the garbage rots, an unpleasant odor does not occur. Furthermore, since drying of garbage can be accelerated without raising the first and second heating means to high temperatures, there is no possibility that the garbage will burn inside the garbage container. For this reason, the safety of the garbage disposal machine can be ensured.
[0017]
Preferably, the garbage processing machine further includes an inner container in which the garbage is accommodated. The inner container is detachably provided inside the garbage container. According to the garbage processing machine configured as described above, the inner container removed from the garbage container is placed in a place where garbage is generated, such as a kitchen, and the garbage is put into the inner container. . Then, when the inner container is full, the inner container is attached to the garbage container and the garbage is processed. By providing such a detachable inner container, it is not necessary to throw away the garbage to the garbage disposal machine each time, and it is not necessary to install the garbage disposal machine in a small kitchen. Moreover, by providing the inner container in which the garbage is directly stored separately from the first heating means, it is possible to prevent the juice dripping from the garbage from adversely affecting the first heating means.
[0018]
Furthermore, it is preferable that the garbage processing machine includes a plurality of inner containers. In this case, while the empty inner container is installed and used in a kitchen or the like, the inner container filled with the garbage can be attached to the garbage container and the garbage can be processed.
[0019]
Preferably, the inner container is provided in contact with the inner side of the side wall. According to the garbage processing machine comprised in this way, the heating of the garbage by the 1st heating means performed via the side wall of a garbage accommodating part can be performed efficiently.
[0020]
Preferably, the garbage processing machine further includes a guide member for guiding the inner container when the inner container is inserted into the garbage container. The guide member is provided between the garbage container and the inner container. According to the garbage processing machine comprised in this way, an inner side container can be smoothly attached or detached with respect to a garbage accommodating part.
[0021]
Preferably, the garbage processing machine further includes a drain for discharging the liquid that has entered between the garbage container and the inner container to the outside. The drain is provided in the garbage storage unit. When detaching the inner container from the garbage container, or when putting garbage directly into the inner container, the juice dripping from the garbage may enter between the garbage container and the inner container. There is. According to the garbage processing machine comprised in this way, the liquid which infiltrated between the garbage accommodating part and the inner side container can be discharged | emitted actively outside. Thereby, it is possible to prevent the generation of a strange odor due to the decay of the liquid that has entered, and the sanitary aspect of the garbage disposal machine from being impaired.
[0023]
Preferably, the garbage processing machine further includes a reflux line for refluxing the gas in the internal space. The second heating means is provided on the reflux line. According to the garbage processing machine configured as described above, the gas in the internal space heated to a high temperature by the first and second heating means flows back to the reflux line. Then, this gas can be heated to a higher temperature by the second heating means and supplied to the garbage as hot air. Thereby, compared with the case where external air is heated to high temperature by a 2nd heating means, thermal efficiency can be improved significantly and the drying of garbage by a 2nd heating means can be performed still more efficiently.
[0024]
Preferably, the garbage processing machine further includes a deodorizing device provided on a path through which the gas in the internal space is discharged to the outside by the exhaust means. The gas discharged to the outside by the exhaust means may contain a strange odor depending on the contents of the garbage. According to the garbage processing machine configured as described above, the gas in the internal space containing the off-flavor is discharged to the outside through the deodorizing device, so that the off-flavor can be prevented from drifting outside.
[0025]
Further preferably, the first heating means is a heater arranged in a spiral shape outside the side wall. According to the garbage processing machine comprised in this way, the heating of the garbage by a 1st heating means can be performed uniformly in the side wall of a garbage accommodating part.
[0026]
  A garbage disposal method according to the present invention is a side wall extending inclined with respect to a vertical direction, and defines an internal space for accommodating garbage.Cylindrical shapeSide wallAnd a bottom surface that closes one end of the side wallAnd moving the garbage along the inside of the side wall by stirring the garbage with a stirring means provided in the internal space, and Simultaneously with the step of dropping the garbage from the inner upper portion toward the lower portion and the step of stirring the garbage, the first heating means provided on the outer side of the side wall moves along the inner side of the side wall. While heating the garbage and supplying the gas for drying the garbage falling from the upper part toward the lower part by the second heating means and the process of stirring the garbage, And a step of discharging the gas to the outside by an exhaust means.
[0027]
According to the garbage processing method configured as described above, the step of stirring the garbage by the stirring means, the step of heating the garbage by the first and second heating means performed simultaneously with this step, the exhaust The garbage thrown into the garbage container is dried by the step of discharging the gas in the internal space by the means.
[0028]
The step of drying the garbage will be described in more detail. In the step of stirring the garbage, the garbage is actively brought into contact with the atmosphere of the internal space to dry the garbage. At this time, the atmosphere in the internal space is heated to a high temperature by the first and second heating means. Further, a gas such as steam generated from the garbage is sequentially discharged to the outside by the exhaust means without filling the internal space. For this reason, drying of garbage by the process of stirring garbage is promoted.
[0029]
Further, the garbage is caused to move in a predetermined manner inside the garbage container by the process of stirring the garbage. That is, the garbage is moved along the inside of the side wall, and the garbage that has reached the upper part inside the side wall in the vertical direction is dropped toward the lower part. The movement of the garbage is made possible by the side wall of the garbage storage portion extending while being inclined with respect to the vertical direction. Then, the garbage moving at a predetermined position is dried by the first and second heating means.
[0030]
In the process of heating the garbage by the first heating means, the garbage is moved with respect to the side wall of the garbage accommodating portion, so that new garbage is heated one after another. For this reason, heating of garbage by the 1st heating means can be performed uniformly with respect to the whole garbage, and drying of garbage can be performed efficiently. Further, in the step of supplying the gas by the second heating means, the gas for drying the garbage is supplied to the garbage falling from the upper part of the side wall toward the lower part. Thus, by sequentially supplying the gas heated to a high temperature to the garbage flowing in the internal space, the garbage can be efficiently dried by the second heating means.
[0031]
As described above, the step of stirring the garbage by the stirring means, the step of heating the garbage by the first and second heating means performed simultaneously with this step, and the step of discharging the gas by the exhaust means Thus, it is possible to continuously and continuously dry garbage. For this reason, garbage can be dried in a short time, and time reduction of a garbage disposal process can be aimed at.

[0045]
FIG. 3 is a cross-sectional view showing the garbage processing machine in a state in which the bucket in FIG. 1 is removed from the garbage containing portion. With reference to FIG. 3, the bucket 15 removed from the garbage processing machine 1 is installed in a place such as a kitchen where garbage is generated. Moreover, the garbage processing machine 1 may include a plurality of buckets 15. In this case, while installing the bucket 15 in a kitchen or the like, the other bucket 15 can be attached to the garbage processing machine 1 to perform the processing of the garbage.
[0046]
A handle 31 is provided on the upper end side of the side wall of the bucket 15. In a state where the lid 16 is opened, the bucket 15 can be removed from the garbage container 2 by pulling the handle 31 toward the front. At this time, when the bucket 15 is removed, the coupling between the coupling 23 and the drive pulley of the transmission device 24 is released. Then, the stirring blade 6 is separated from the garbage processing machine 1 together with the bucket 15. For this reason, the bucket 15 is installed in a kitchen or the like with the stirring blades 6 provided. When the bucket 15 is inserted into the garbage container 2 and installed at a predetermined position, the coupling 23 and the drive pulley of the transmission 24 are automatically connected. Thereby, the stirring blade 6 can be rotated again via the transmission device 24 and the coupling 23.
[0047]
The garbage processing machine 1 according to the first embodiment of the present invention includes a side wall 3 that is inclined and extends with respect to a vertical direction, and has a side wall 3 that defines an internal space for containing the garbage. A waste container 2, a stirring blade 6 provided as an agitation means for agitating the garbage, and a first heating means provided outside the side wall 3 for heating the garbage through the side wall 3. , A hot air heater 7 as a second heating means for supplying a gas for drying the garbage stored in the internal space, and an exhaust fan as an exhaust means for exhausting the gas in the internal space to the outside 21.
[0048]
The garbage disposal machine 1 further includes a bucket 15 as an inner container in which the garbage is accommodated. The bucket 15 is provided in contact with the inside of the side wall 3. The garbage processing machine 1 further includes a drain hose 27 as a drain for discharging the liquid that has entered between the garbage container 2 and the bucket 15 to the outside. The stirring blade 6 is a blade-shaped member that moves along the inside of the side wall 3. The garbage disposal machine 1 may include a plurality of buckets 15.
[0049]
The garbage disposal machine 1 further includes a reflux line 11 for refluxing the gas in the internal space. The hot air heater 7 is provided on the reflux line 11. The garbage disposal machine 1 further includes a deodorizing device 10 provided on the exhaust duct 19 as a path through which the gas in the internal space is exhausted to the outside by the exhaust fan 21. The heater 5 is a heater arranged in a spiral shape outside the side wall 3.
[0050]
Then, the process of drying and processing garbage with the garbage processing machine 1 is demonstrated. Referring to FIG. 1, a bucket 15 into which raw garbage is thrown in a kitchen or the like is inserted into the raw food storage unit 2. In addition, you may throw in garbage directly in the bucket 15 with which the garbage processing machine 1 was installed in the kitchen etc. by installing it. The operation panel 28 is operated to energize the motor 25, the fan 14, the exhaust fan 21, the hot air heater 7 and the heater 5.
[0051]
FIG. 4 is a cross-sectional view showing the state of garbage stored in the bucket when the stirring blade is rotated. With reference to FIG. 4, the stirring blade 6 rotates inside the bucket 15 by energizing the motor 25. As the stirring blade 6 rotates, the garbage rotates around the central axis 8 inside the bucket 15. At this time, since the centrifugal force acts on the rotating garbage, the garbage 43 a moves along the side wall of the bucket 15.
[0052]
Moreover, the garbage which moved to the upper part 41 located upward in the vertical direction falls toward the lower part 42 located downward in the vertical direction. At this time, since the side wall of the bucket 15 is inclined with respect to the vertical direction, the garbage 43 b falling from the upper portion 41 toward the lower portion 42 is in a state of dancing in the atmosphere inside the bucket 15.
[0053]
As described above, by rotating the stirring blade 6, the garbage 43a moves along the side wall of the bucket 15, and the garbage 43b falls from the upper part 41 toward the lower part 42. Can be repeated inside the bucket 15.
[0054]
Note that the shape of the stirring blade 6 may be changed as appropriate in order to allow the garbage to perform the above-described movement cycle efficiently. Examples of such a change in the shape of the stirring blade 6 include changing the number of blade members constituting the stirring blade 6 or changing the angle at which the blade member is provided with respect to the side wall of the bucket 15. Further, the stirring blade 6 may be formed so that the blade member extends in the direction of the central axis 8 while drawing a curve.
[0055]
By energizing the heater 5, the heat generated from the heater 5 is transmitted through the side wall 3 of the garbage container 2 and reaches the bucket 15. At this time, since the garbage accommodating part 2 and the bucket 15 are in contact, the heat generated from the heater 5 can be efficiently transmitted. The heat generated from the heater 5 mainly heats the garbage 43a moving along the side wall of the bucket 15. At this time, the heater 5 is controlled so that the heating temperature of the garbage becomes about 140 ° C. The higher the heating temperature, the faster the garbage can be dried. However, when the heating temperature is higher than a predetermined temperature, vegetables contained in the garbage may ignite. For this reason, it is preferable to set the heating temperature of the garbage by the heater 5 to about 140 ° C.
[0056]
The garbage which contacts the side wall of the bucket 15 is always replaced by the rotation of the stirring blade 6. For this reason, garbage will be in the state heated while repeating a movement on the frying pan (side wall of the bucket 15) heated to high temperature. Thereby, the heating of the garbage by the heater 5 is performed uniformly with respect to the whole garbage, and a garbage can be dried efficiently.
[0057]
In addition, when the method of rotating the bucket 15 itself as a stirring means for stirring the garbage is employed, the relative movement between the garbage and the side wall of the bucket 15 cannot be sufficiently promoted. For this reason, if it says only in the above-mentioned effect, this Embodiment which employ | adopted the blade-shaped member which moves along the side wall of a garbage accommodating part as a stirring means is more effective.
[0058]
Referring to FIGS. 1 and 4, by energizing fan 14, the gas inside bucket 15 is guided from suction port 13 to reflux line 11. The gas led to the reflux line 11 eventually reaches the hot air heater 7 and is heated to a temperature of about 130 ° C. by the hot air heater 7 that is energized. Then, hot air is supplied from the blower opening 12 toward the inside of the bucket 15.
[0059]
Inside the bucket 15, the hot air advances in the direction indicated by the arrow 45 (see FIG. 4) and is supplied to the garbage 43 b falling from the upper portion 41 toward the lower portion 42. The garbage 43b is in a state of dancing in the atmosphere inside the bucket 15. For this reason, garbage 43b will be in the state where the wind of the dryer was applied by hot air being sprayed. Thereby, garbage can be dried efficiently.
[0060]
Further, by introducing the gas inside the bucket 15 into the reflux line 11 and heating it with the hot air heater 7, hot hot air is supplied. For this reason, the thermal efficiency which heats garbage with the hot air heater 7 can be improved.
[0061]
In the present embodiment, the garbage containing portion has an upper portion located above the side wall in the vertical direction and a lower portion located below the side wall in the vertical direction. The downstream end of the reflux line is provided so that hot air from the downstream end is supplied on a line connecting the upper part and the lower part of the garbage container.
[0062]
By energizing the exhaust fan 21, steam generated inside the bucket 15 is discharged to the outside through the relay duct 19 a and the exhaust duct 19. At this time, the steam passes through the deodorizing device 10 provided in the middle of the exhaust duct 19. Since a high-performance catalyst for reducing odor is provided inside the deodorizing apparatus 10, no off-flavor is emitted to the outside. The steam further passes through the cooling device 35. The steam is cooled by the cooling device 35. For this reason, the steam is discharged in a water state to a drain pipe to which the other end of the exhaust duct 19 is connected.
[0063]
The atmosphere inside the bucket 15 is heated to a high temperature by the heater 5 and the hot air heater 7. Further, steam generated from the garbage inside the bucket 15 is sequentially discharged to the outside by the exhaust fan 21. Therefore, a high-temperature atmosphere suitable for drying garbage is formed inside the bucket 15. Then, by rotating the stirring blade 6 inside the bucket 15, the contact between the high temperature atmosphere and the garbage is repeated one after another. Thereby, drying of garbage can be promoted.
[0064]
When drying of the garbage stored in the bucket 15 is completed, energization to each device of the garbage processing machine 1 is stopped. At this time, by incorporating a sensor in the garbage processor 1, it is possible to detect the dry state of the garbage and automatically control the operation. As a method of detecting the dry state by the sensor, a method of measuring humidity or measuring temperature inside the bucket 15 can be considered. By adopting such a method, it is possible to determine a uniform dry state regardless of the type or amount of garbage.
[0065]
Assuming a case where 10 (L) of garbage is processed by the garbage processor 1, the garbage can be completely dried in about 2 to 3 hours. For this reason, when the garbage processing machine 1 is used for household use, it is possible to complete the processing of the garbage discharged from the previous meal before the garbage discharged from the meal is put into the bucket 15. it can.
