Description

  The present invention relates to an organic matter processing machine, and more particularly to an organic matter processing machine that processes organic matter such as food waste discharged in the process of manufacturing, distributing, selling, and consuming food.

  Conventionally, this kind of organic matter processing machine is a garbage processing machine that stirs while heating the garbage in the treatment tank, and fermented and decomposes the garbage with microorganisms. The odor in the exhaust gas produced is deodorized by a deodorizing device.

  In practice, the deodorization device is provided in an exhaust path communicating with the outside from the treatment tank. For example, the catalyst is heated at an activation temperature by a catalyst heating means such as an electric heater, and the treatment tank is used with the catalyst at the activation temperature. Is deodorized by decomposing malodorous components in the exhaust gas from the exhaust gas (for example, see Patent Document 1).

  And in such a garbage processing machine, as shown in FIG. 4, it is comprised with the power switch 101 which supplies electric power to various circuit blocks, and starts to an operable state, the deodorizing switch 102, and the operation switch 103 When the operation mode for fermenting and decomposing the garbage in the processing tank is selected by pushing the operation switch 103 and pressing the other deodorization switch 102, the deodorization switch 102 is pressed. Deodorization stop operation mode that stops the operation of the deodorizing device every time the switch 102 is operated, and a strong deodorizing exhaust gas in a state where the catalyst is heated to a predetermined high temperature by an electric heater and the deodorizing ability of the catalyst is enhanced. The deodorization operation mode and the weak deodorization operation mode in which the exhaust gas is deodorized in a state where the catalyst is heated at a lower temperature than the strong deodorization operation mode and the deodorizing ability by the catalyst is lowered can be selected in order Uninasa are. In the figure, reference numerals 105 and 106 denote operation display lamps. When the above strong deodorization operation mode is selected, the operation display lamp 105 is turned on. On the other hand, when the weak deodorization operation mode is selected, another operation display lamp 106 is lit. It has become.

Thus, in the garbage processing machine, the user can select a desired operation mode by pressing the deodorizing switch 102 in accordance with the intensity of bad odor.
JP 2002-143810 A

  In the above configuration, the odor level (odor intensity) in the operation mode in which the raw garbage is decomposed and fermented is increased when the temperature in the treatment tank is high, as shown in FIG. When the temperature in the processing tank is low, the temperature becomes weak. In other words, the odor varies depending on the operation time and the heating conditions in the treatment tank.

  However, since the user selects the operation mode of deodorization based on the odor level when it is inevitably strong, even when the heating temperature in the treatment tank is actually low and the odor level is low, the user operates the electric heater of the deodorization device in the strong operation mode. The catalyst may be heated more than necessary to increase the activation temperature of the catalyst. For this reason, the conventional garbage processing machine has a very high running cost (electricity cost). In addition, in order to reduce the running cost, the user himself / herself needs to press the deodorizing switch 102 to switch between the strong and weak operation of the deodorizing device in accordance with the odor level, forcing the user to perform troublesome operations. There was a problem.

  Some deodorizers are always operated with a certain deodorizing capability during garbage disposal without requiring the user to operate the deodorizer, but this is also a criterion for determining when the odor level is high. As described above, the deodorizing ability is set in advance. For this reason, as in the above-described strong deodorizing operation mode, the catalyst is usually heated at a high temperature by the electric heater, so that the running cost is very high.

  By the way, in such a garbage processing machine, the stirring means is disposed in the treatment tank, and the stirring blades of the stirring means are rotated by a motor so that the garbage is stirred in the treatment tank to make aerobic microorganisms. Oxygen is supplied and the food waste is fermented and decomposed, but if the food waste is mixed with meat chunks, fish heads, or other large cooking debris, the processing does not end within a predetermined processing time. Conventionally, in order to avoid such a problem, a cumbersome and time-consuming process such as finely crushing garbage is necessary as a pretreatment for fermentation decomposition. In addition, when the garbage processor and the crushing device are separate, it takes time to pulverize the crushing device and to operate the crushing device, and to move the crushed garbage to the garbage processing device. There were many problems, such as taking.

  Furthermore, in such a garbage processing machine, when the fermentation decomposition of the garbage is completed and the residue is discharged from the processing tank, the discharge is performed after a predetermined container is set in the discharge port formed in the processing tank. A method is adopted in which a switch (not shown) is pressed to rotate the stirring blades of the stirring means, whereby the residue in the treatment tank is discharged from the discharge port with the stirring. However, since this stirring means is for fermenting and decomposing the garbage in the treatment tank, the speed of rotating the stirring blade is slow, and it takes time until the discharge of the residue is completed.

  The present invention has been made in consideration of the above points, and it is a first object of the present invention to provide an organic matter processing machine capable of performing optimal deodorization according to odor without forcing the user to perform troublesome operations and reducing running costs. One purpose.

  In addition, there is no need to grind the crushing equipment, the cost of operating the crushing equipment, the trouble of transferring the crushed garbage to the garbage treatment machine, and further propose an organic matter treatment machine that can shorten the processing time of fermentation decomposition The second purpose is to do.

  Furthermore, a third object is to propose an organic matter processing machine that can discharge residues in a short time.

  In the organic matter processing machine according to claim 1 of the present invention, since the operation of the deodorizing means and the like is controlled by the control means according to the detection level of the odor detecting part, the odor detecting part detects the bad odor when processing the organic matter. Since the operation is switched by this, the user himself / herself can save the trouble of switching the operation each time according to the odor. In addition, since the drive power consumption of the deodorizing means and the like can be kept to the minimum necessary according to the odor level, the power consumption can be reduced.

  In the organic matter processing machine according to claim 2 of the present invention, if the odor is eliminated by setting the predetermined detection level of the odor detection unit in advance to a level at which the user hardly feels odor, troublesome to the user accordingly. The operation can be stopped without forcing an unnecessary operation, and a useless running cost can be suppressed.

  In the organic matter treating machine according to claim 3 of the present invention, when a catalyst containing platinum, palladium or platinum and palladium as a component is used in a deodorizing apparatus, the deodorizing performance of the catalyst itself is good, and the catalyst heating means Since the components that can be decomposed differ depending on the heating temperature when the catalyst is heated, the deodorizing ability of the deodorizing means can be easily increased or decreased simply by changing the heating temperature for the catalyst.

  In the organic matter treating machine according to claim 4 of the present invention, when the odor is strong, the catalyst heating means is raised to increase the deodorizing ability, and when the odor is weak, the catalyst heating means is lowered to lower the deodorizing ability. Therefore, it is possible to minimize the energization to the catalyst heating means according to the odor.

  In the organic matter processing machine according to claim 5 of the present invention, large garbage can be crushed quickly by setting the stirring speed of the stirring means to a predetermined speed faster than usual for a predetermined time from the start of processing of the organic matter. By increasing the surface area of the garbage, biodegradation and water evaporation by heating can be performed effectively, so that the fermentation decomposition treatment time can be shortened. In addition, there is no need for a crushing drive source, and there is no need to separately crush organic matter with a crushing device, to operate the crushing device, and to move crushed garbage to a garbage processing machine.

  In the organic matter processing machine according to claim 6 of the present invention, when the residue is discharged, the stirring speed of the stirring means is set to a predetermined speed that is higher than usual, so that the number of discharges associated with stirring increases, so that from the inside of the processing tank in a short time More residue can be discharged.

  In the organic matter processing machine according to claim 1 of the present invention, optimal deodorization according to odor can be performed without forcing the user to perform troublesome operations, and the running cost can be reduced.

  In the organic matter processing machine according to claim 2 of the present invention, it is possible to stop the operation of the deodorizing apparatus without forcing the user to perform troublesome operations, and to reduce wasteful power consumption.

  In the organic matter treating machine according to claim 3 of the present invention, the deodorizing ability of the deodorizing means can be easily increased or decreased by merely changing the heating temperature for the catalyst.

  In the organic matter processing machine according to claim 4 of the present invention, it is possible to minimize energization to the catalyst heating means according to the odor, and wasteful power consumption can be reduced.

  In the organic matter processing machine according to claim 5 of the present invention, there is no need to grind in the crushing device, the cost of operating the crushing device, and the labor of transferring the crushed garbage to the garbage processing machine, and further, the fermentation decomposition treatment Time can be shortened.

  In the organic matter processing machine according to claim 6 of the present invention, the residue can be discharged in a short time.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

  1, 2 and 3, reference numeral 1 denotes a garbage processing machine corresponding to the organic matter processing machine of the present invention. The garbage processing machine 1 has a garbage (not shown) in a housing 2. In order to carry out ventilation and deodorization in the processing tank 3 for fermenting and decomposing, the stirring means 4 for stirring and mixing the garbage and the aerobic microorganism carrier in the processing tank 3, and the processing tank 3 The operation unit 8 (FIG. 3) for inputting various instruction commands is provided on the side surface of the housing 2.

  The processing tank 3 is provided with an input port 6 for supplying garbage into the processing tank 3 at an upper portion 3A thereof, and an input lid 7 configured to be able to open and close the input port 6.

  Further, a drive shaft 10 of the agitating means 4 is provided between the front wall 3B and the rear wall 3C of the processing tank 3 so as to be rotatable in the horizontal direction. It is formed in a U-shaped cross section that forms an arc shape in accordance with the rotation trajectory of the plurality of stirring blades 11 erected at 10.

  Further, on one side wall 3 </ b> E of the treatment tank 3, discharge means 12 for discharging the garbage residue after the fermentation decomposition from the inside of the treatment tank 3 is provided. The discharge means 12 includes a discharge port 13 formed in the side wall 3E of the processing tank 3, and a discharge door 14 configured to open and close the discharge port 13. In practice, the discharge port 13 is formed at a position where the residue can be discharged from the treatment tank 3 by overflow as the stirring means 4 stirs.

  The stirring means 4 in the processing tank 3 is supported by bearings 15 on both ends of the drive shaft 10 on bearings 15 provided on the front wall 3B and the rear wall 3C, and the shaft end on the rear wall 3C side. The drive motor 17 is connected to the sprocket 16 provided in the shaft via a roller chain (not shown), so that the rotation of the drive motor 17 is transmitted to the drive shaft 10, whereby the stirring blade 11 is removed from the processing tank. 3 can be rotated.

  Incidentally, in the case of this embodiment, the drive motor 17 can rotate the drive shaft 10 of the stirring means 4 at either a slow rotation speed of about 4 rpm or a higher rotation speed of about 10 rpm, for example. The slow rotation speed is set as the normal rotation speed.

  Further, the inside of the processing tank 3 is heated by a planar heater 18 as a heating means provided on the outer surface of the bottom 3D of the processing tank 3, and thus the temperature in the processing tank 3 is in an optimum range for activation of aerobic microorganisms. The gas generated in the treatment tank 3 at this time can be discharged to the outside through the ventilation deodorizing device 5.

  Here, the ventilation deodorizing device 5 is a tubular exhaust duct composed of an exhaust fan 20, a deodorizing device 21 as a deodorizing means for deodorizing the exhaust from the treatment tank 3, and a heat-resistant duct hose as an exhaust path. 22, a heat exchanger 23, and a tubular intake duct 24 as an intake passage communicating with the heat exchanger 23 from the outside.

  In practice, as shown in FIG. 2, the deodorizing apparatus 21 has a rod-shaped sheathed heater 26 as a catalyst heating means disposed inside the cylindrical portion 25, and is carried on the surface of the honeycomb structure stainless steel on the downstream side thereof. A platinum catalyst 27 is disposed, and the sheathed heater 26 can heat the platinum catalyst 27 to either a low temperature (for example, about 200 ° C.) or a high temperature (for example, about 300 ° C.).

  Incidentally, since the platinum catalyst 27 has platinum as a main component, an odor component that can be decomposed changes according to a temperature change. In this case, for example, ammonia and ethylene can be decomposed and purified at about 200 ° C., for example, acetaldehyde can be decomposed and purified at about 250 ° C., and, for example, ethyl acetate can be decomposed and purified at about 300 ° C. at a higher temperature. Thus, the deodorizing ability can be improved by changing the temperature of the platinum catalyst 27.

  The exhaust duct 22 includes a duct (hereinafter referred to as a treatment tank communication duct) 29 that communicates from the intake port 28 of the treatment tank 3 to the deodorization apparatus 21, and a duct (hereinafter referred to as a heat exchanger 23) that communicates from the deodorization apparatus 21 to the heat exchanger 23. This is called an intermediate duct (30) and a duct (hereinafter referred to as an external communication duct) 31 communicating from the heat exchanger 23 to the outside, and the treatment tank communication duct 29 and the external communication duct 31 exchange heat. Crossed with vessel 23.

  Thus, the exhaust gas generated in the processing tank 3 passes through the intake port 28, the processing tank communication duct 29, the cylindrical portion 25 of the deodorizing device 21, the platinum catalyst 27, the intermediate duct 30 and the heat exchanger 23 by the blower 20 in sequence. At this time, in the heat exchanger 23, the exhaust gas deodorized by the deodorizing device 21 is heat-exchanged with the outside air from the intake duct 24. Incidentally, the intake duct 24 is for taking in oxygen necessary for aerobic microorganisms from the outside.

  In practice, in this heat exchanger 23, the outside air supplied into the treatment tank 3 is heated to a predetermined temperature, so that the temperature of the garbage that is the object to be treated is kept at the predetermined temperature, and the garbage is efficiently collected. It is comprised so that fermentation decomposition | disassembly can be carried out. Incidentally, the exhaust gas supplied from the deodorizing device 21 and heat-exchanged in the heat exchanger 23 is exhausted from the external communication duct 31 to the outside.

  In addition to this configuration, the processing tank communication duct 29 located on the downstream side of the processing tank 3 is provided with an odor detection unit 35 made of, for example, a gas sensor, and is sent from the processing tank 3 by the odor detection unit 35. The odor level in the exhaust gas is always detected, and the detection result is given to the control unit 36.

  The intermediate duct 30 located downstream of the platinum catalyst 27 is provided with an exhaust temperature detection unit 37. The exhaust temperature detection unit 37 constantly detects the temperature of the exhaust gas that has passed through the platinum catalyst 27. The detection result is given to the control unit 36.

  The control unit 36 is configured to include a CPU (Central Processing Unit) that controls the entire garbage disposal machine 1 in an integrated manner. In addition to the odor detection unit 35 and the exhaust gas temperature detection unit 37, the control unit 36 includes an operation unit. The part 8, the sheet heater 18, the sheathed heater 26, the drive motor 17, and the like are connected.

  In this case, the control unit 36 is a deodorizing device control program stored in advance in a ROM (Read Only Memory) (not shown) in the control unit 36 in accordance with various commands input via the operation unit 8. Various programs such as an agitation start control program and a discharge agitation control program are read out and developed on a RAM (Random Access Memory) (not shown) in the control unit 36. It is designed to realize various functions.

  The operation unit 8 includes a power switch 8A that supplies power to various circuit blocks to start operation, and a weak deodorization operation mode in which deodorization is performed with the platinum catalyst 27 in a low temperature state or a platinum catalyst 27 in a high temperature state. A deodorizing switch 8B capable of selecting any one of the strong deodorizing operation modes for deodorizing and a discharging operation switch 8C for shifting to a discharging mode for discharging residues from the processing tank 3 are provided.

  In practice, when the power switch 8A is pressed, the control unit 36 starts to energize the drive motor 17 by executing a built-in stirring start control program, and rotates the drive shaft 10 of the stirring means 4 to rotate the processing tank 3. The stirring operation of the stirring means 4 is started in order to reduce the amount of organic matter inside. At this time, the control unit 36 controls the energization to the drive motor 17 so that the rotation speed is faster (in this case, faster than 4 rpm) only for a predetermined time (in this case, for example, about 1 hour) from the start of the stirring operation. 10 rpm), the mode is changed to a mode in which the drive shaft 10 and hence the stirring means 4 are rotated (hereinafter referred to as a stirring start mode). After that, the control unit 36, after a certain time (preset time, for example, about 1 hour) has elapsed from the start of the stirring operation, from the stirring start mode, the normal rotation speed (this speed is reduced) In this case, the mode is switched to a mode in which the drive shaft 10 and hence the stirring means 4 are rotated at about 4 rpm (hereinafter referred to as a normal stirring mode), and then the stirring blade 11 is continuously rotated at this slow normal rotation speed.

  By the way, the control unit 36 becomes a standard for stopping the operation of the deodorizing device 21 and a predetermined odor level (hereinafter referred to as a switching odor level) that serves as a standard for switching between the strong and weak operation of the deodorizing device 21. A predetermined odor level (hereinafter referred to as a stop odor level) is set in advance, and is received from the odor detector 35 by executing the deodorizer control program when executing the stirring start mode and the normal stirring mode. Based on the detection result, it is determined whether or not the odor level in the treatment tank communication duct 29 has reached this switching odor level and is equal to or lower than the stop odor level. At the same time, based on the detection result received from the exhaust gas temperature detection unit 37, the control unit 36 energizes the sheathed heater 26 that heats the platinum catalyst 27 so that the temperature of the exhaust gas that has passed through the platinum catalyst 27 approaches the set temperature. To control.

  Thereby, in the control part 36, when the odor level in the processing tank communication duct 29 (that is, the odor level in the processing tank 3) is high and reaches the switching odor level based on the detection result from the odor detection part 35. The sheathed heater 26 of the deodorizing apparatus 21 is controlled so that the platinum catalyst 27 is always operated in the strong deodorizing operation mode in which the heating temperature of the platinum catalyst 27 is increased. That is, the control unit 36 switches the odor level in the processing tank communication duct 29 based on the detection result from the odor detection unit 35 while executing the weak deodorization operation mode in which the exhaust temperature from the platinum catalyst 27 is low. If it is determined that the odor level has been reached, the mode is forcibly switched to the strong deodorization operation mode, the heating of the sheathed heater 26 is strengthened, the platinum catalyst 27 is maintained at a high temperature, and the deodorizing capability of the deodorizing device 21 is improved.

  On the other hand, when the odor level in the treatment tank communication duct 29 is low and does not reach the switching odor level, the control unit 36 controls the sheathed heater 26 of the deodorizing device 21 so as to always operate in the weak deodorizing operation mode. That is, the control unit 36 switches the odor level in the treatment tank communication duct 29 based on the detection result from the odor detection unit 35 while executing the strong deodorization operation mode in which the exhaust temperature from the platinum catalyst 27 is high. If it is determined that the odor level has not been reached, the mode is forcibly switched to the weak deodorization operation mode, the heating of the sheathed heater 26 is weakened, and the platinum catalyst 27 is maintained at a low temperature. In this case, in the deodorizing device 21, the platinum catalyst 27 can be maintained at a low temperature, so that energization to the sheathed heater 26 can be reduced.

  Furthermore, when the detection result by the odor detection unit 35 is equal to or lower than the stop odor level, the control unit 36 can also stop the heating of the platinum catalyst 27 by stopping energization of the sheathed heater 26. Thereafter, when the detection result by the odor detection unit 35 again becomes equal to or higher than the stop odor level, the control unit 36 starts energization to the sheathed heater 26 of the deodorizing device 21 and heats the platinum catalyst 27 again.

  In addition to this, when the discharge operation switch 8C is pressed, the control unit 36 executes the discharge stirring control program to switch from the normal stirring mode to the residue discharging mode, and to drive the drive motor 17 to rotate rapidly. Thus, the stirring blade 11 is started to rotate at a rotational speed (in this case, about 10 rpm) faster than the normal stirring mode. After that, for example, when the discharge operation switch 8C is pressed again, the control unit 36 switches the discharge motor from the discharge mode to the normal stirring mode by rotating the drive motor 17 again slowly, and rotates the stirring blade 11 at a low rotation speed. Continue to let.

  In the above-described configuration, in the garbage processing machine 1 according to the present embodiment, by opening the input lid 7 and introducing the garbage into the treatment tank 3 from the input port 6, the garbage and the garbage are disposed in the treatment tank 3. It contains a carrier of aerobic microorganisms that fermentatively decompose garbage. In this state, the operation is started by closing the closing lid 7 and depressing the power switch 8A, and the control unit 36 performs the planar heater 18, the drive motor 17, the sheath heater 26 of the deodorizing device 21, the heat exchanger 23, and the blower. Energization control to 20 is performed.

  The control unit 36 executes a stirring start mode for a predetermined time at the start of garbage processing immediately after operating the power switch 8A. In this stirring start mode, the drive motor 17 is driven to rotate at a high speed, and the driving force of the drive motor 17 is transmitted to the drive shaft 10 via the roller chain and sprocket 16 so that the plurality of stirring blades 11 have a higher rotational speed than usual. Rotate with. Thereby, a lump of meat, a fish head, and other large garbage are sandwiched between the side part and the bottom part in the processing tank 3 in a short time by the stirring blade 11, and can be finely crushed.

  Thus, even when a large amount of garbage is input, the surface area of the garbage is increased by reliably crushing it at the initial stage of the addition, and the garbage and aerobic microorganisms in the treatment tank 3 are increased. The carrier can be reliably mixed in a short time to facilitate biodegradation and water evaporation by heating. Therefore, the fermentation decomposition time of food waste can be shortened, and thus food waste can be efficiently fermented and decomposed. In addition, there is no need for a crushing drive source, and there is no need to separately crush organic matter with a crushing device, to operate the crushing device, and to move crushed garbage to a garbage processing machine.

  After that, when a preset fixed time has passed, the mode automatically switches from the stirring start mode to the normal stirring mode, and after crushing large garbage finely, the rotation speed of the stirring blade 11 is decreased. Thus, the power consumption by the drive motor 17 can be suppressed to the minimum necessary, and thus the power consumption can be further reduced as compared with the conventional case. At the same time, the temperature in the treatment tank 3 is maintained within the optimum range for the activation of the aerobic microorganisms by the planar heater 18, and the microorganisms cultured on the carrier while rotating the stirring blade 11 at a normal rotation speed. The food waste is decomposed into carbon dioxide and water and composted.

  The exhaust gas generated as the garbage in the treatment tank 3 is reduced is supplied by the blower 20 to the cylindrical portion 25 of the deodorizing device 21 through the treatment tank communication duct 29. It is supplied to the platinum catalyst 27 while being heated by the sheathed heater 26. At this time, the exhaust gas having an odor passes through the platinum catalyst 27 that is also heated by the sheathed heater 26, so that the odor component is oxidatively decomposed and deodorized. The deodorized exhaust gas is supplied to the heat exchanger 23 and subjected to heat exchange, and then discharged to the outside through the external communication duct 31. Here, if the exhaust gas supplied from the inside of the treatment tank 3 has a strong bad odor and the odor level of the odor detection unit 35 has reached the switching odor level, the control unit 36 strongly operates the garbage disposal machine 1. In the deodorizing operation mode, the energization rate of the sheathed heater 26 is increased to increase the heating of the platinum catalyst 27, and as a result, the temperature of the platinum catalyst 27 is increased to improve the deodorizing ability.

  On the other hand, if the exhaust gas supplied from the inside of the treatment tank 3 has a weak bad odor and the odor level of the odor detection unit 35 is lower than the switching odor level, the control unit 36 operates the garbage disposal machine 1. In the weak deodorization operation mode, the energization rate of the sheathed heater 26 is lowered to weaken the heating of the platinum catalyst 27, and as a result, the temperature of the platinum catalyst 27 is lowered to lower the deodorizing ability. Even when the deodorizing ability is thus reduced, the odor level in the exhaust gas is low, so that the malodorous component in the exhaust gas can be sufficiently decomposed and deodorized.

  Thus, it is possible to save the user himself from pressing the deodorizing switch 8B each time according to the odor level to switch to the deodorizing operation or the weak operation mode today. Further, by weakening the heating of the sheathed heater 26, the power consumption can be kept to the minimum necessary according to the odor level, and the power consumption can be reduced.

In addition, when the odor level hardly feels odor for the user, the odor level from the odor detection unit 35 becomes lower than the stop odor level, and the energization to the sheathed heater 26 of the deodorizer 21 is stopped accordingly. Therefore, when the odor level becomes low and the user no longer feels odor, the sheathed heater 26 of the deodorizing device 21 can be surely stopped, so that useless power consumption can be reduced. In addition, when the odor level at which the user feels odor is reached, the sheath heater 26 of the deodorizing device 21 starts to be heated again, and the deodorization is resumed by the platinum catalyst 27. By the way, when the residue accumulated in the processing tank 3 is discharged from the processing tank 3, the discharge door 14 of the side wall 3E is first opened and the discharge port 13 is opened. In this state, after setting a container (not shown) in the discharge port 13 and switching to the residue discharge mode by depressing the discharge operation switch 8C, the control unit 36 starts to drive the drive motor 17 to rotate rapidly. The driving force of the motor 17 is transmitted to the drive shaft 10 via the roller chain and the sprocket 16, and the plurality of stirring blades 11 rotate at a rotational speed faster than usual.

  As a result, when the stirring blade 11 passes near the discharge port 13, the residue near the discharge port 13 is raised, thereby overflowing the residue from the discharge port 13 and discharging the residue into the container set in the discharge port 13. I will let you. At this time, since the rotation speed of the stirring blade 11 is fast, the number of times the stirring blade 11 passes through the vicinity of the discharge port 13 can be increased, and the number of times of overflow of the residue by the stirring blade 11 can be increased. More residue can be discharged from within. Thereafter, when the discharge operation is finished and the discharge operation switch 8C is pressed again, the stirring blade 11 can be started to rotate again at a low rotation speed.

  As described above, in the present embodiment, the processing tank 3 for fermenting and treating organic garbage, the stirring means 4 for stirring the garbage in the processing tank 3, and the garbage in the processing tank 3 are used. Are provided in a sheet heater 18 as a heating means, a deodorizing device 21 as a deodorizing means for deodorizing exhaust from the treatment tank 3, and an exhaust duct 23 serving as an exhaust gas path. An odor detection unit 35 that detects odors, and a control unit 36 that is a control unit that controls, for example, the strength and weakness operation of the deodorizing device 21 according to the odor level (detection level) of the odor detection unit 35 is provided.

  As described above, the control unit 36 controls the strength and weakness operation of the deodorizing device 21 according to the odor level of the odor detection unit 35. Thus, the strong and weak operation of the deodorizing device 21 is switched, so that the user can save the trouble of switching the strong and weak operation of the deodorizing device 21 each time according to the odor. In addition, since the drive power consumption of the deodorizing device 21 can be kept to the minimum necessary according to the odor level, the power consumption can be reduced, and thus the optimum deodorization according to the odor can be performed without forcing the user to perform troublesome operations. In addition, the running cost can be reduced.

  Further, the control unit 36 of the present embodiment stops the operation of the deodorizing device 21 when the odor in the exhaust duct 23 is equal to or lower than the stop odor level that is a predetermined detection level set in advance, and the odor in the exhaust duct 23 is stopped. When the odor level is exceeded, operation of the deodorizing device 21 is started again.

  In this way, by setting the stop odor level to a level at which the user hardly feels odor and operating the deodorizing device 21, if the bad odor disappears, the user can respond to the deodorizing device without forcing the user accordingly. The operation can be stopped and wasteful power consumption can be reduced.

  Furthermore, in the present embodiment, the deodorizing apparatus 21 includes a sheathed heater 26 that is a catalyst heating unit that uses a platinum catalyst 27 containing platinum as a component and heats the platinum catalyst 27.

  When the platinum catalyst 27 is used in this way, the deodorizing performance of the catalyst itself is good, and when the catalyst is heated by the sheathed heater 26, the components that can be decomposed differ depending on the heating temperature. The deodorizing ability of the deodorizing device 21 can be easily increased or decreased simply by changing the heating temperature with respect to.

  Furthermore, the control unit 36 of the present embodiment has a configuration that controls the platinum catalyst 27 to a higher temperature as the odor level of the odor detection unit 35 is higher. In this way, when the odor is strong, the sheathed heater 26 is raised to increase the deodorizing ability, and when the odor is weak, the sheathed heater 26 is lowered to lower the deodorizing ability, and the sheathed heater 26 is energized according to the odor. Since it can be minimized, useless power consumption can be reduced.

  Furthermore, in a present Example, it is a heating means which heats the garbage in the processing tank 3 which ferments and decomposes | disassembles raw garbage, the stirring means 4 which stirs the garbage in the said processing tank 3, and the garbage in the processing tank 3 A planar heater 18, and a control unit 36 as stirring control means for stirring the stirring means 4 at a predetermined speed, that is, at a higher speed than when the start of the agitation of garbage, for a predetermined time; Is provided.

  In this way, by increasing the rotational speed of the stirring means 4 for a predetermined time from the start of stirring, large garbage can be crushed quickly, thereby increasing the surface area of the garbage, thereby causing biodegradation or heating. Since water evaporation can be performed effectively, the processing time for fermentation decomposition can be shortened. In addition, there is no need for a crushing drive source, and there is no need to separately crush organic matter with a crushing device, to operate the crushing device, and to move crushed garbage to a garbage processing machine.

  Furthermore, in this embodiment, the treatment tank 3 for fermenting and decomposing the garbage, the stirring means 4 for stirring the garbage in the treatment tank 3, and the planar heater 18 as a heating means for heating the garbage in the treatment tank 3 And the discharge means 12 which discharges the residue after the fermentation decomposition process from the inside of the processing tank 3 with stirring by the stirring means 4, and when the residue after the processing in the processing tank 3 is discharged, the stirring means 4 And a control unit 36 as discharge control means for stirring at a high speed which is a predetermined speed.

  As a result, by increasing the rotational speed of the stirring means 4 when discharging the residue, the number of discharges associated with stirring increases, so that more residue can be discharged from the treatment tank 3 in a short time, and thus the residue can be discharged in a short time. Can be discharged.

  In the above-described embodiment, the case where the platinum catalyst 27 is used has been described. However, the present invention is not limited to this, and a catalyst containing palladium as a component or a catalyst containing platinum and palladium is used. Even in this case, as in the above-described embodiment, the deodorizing ability can be changed according to the heating temperature of the sheathed heater, and the same effect as described above can be obtained.

  In the above-described embodiment, the case where the stirring start mode is executed by pressing the power switch has been described. However, the present invention is not limited to this, for example, throwing garbage into the treatment tank. The agitation start mode may be executed by closing the discharge door that has been opened and closed.

  Furthermore, in embodiment mentioned above, although the case where the garbage processing machine which fermented and decomposes garbage was applied as an organic substance processing machine was described, this invention does not restrict to this but processes organic substance If so, you may make it apply to other various organic substance processing machines.

  Further, the operation control of the deodorizing means is not stepwise depending on the strength as in the embodiment, but may be continuously variable.
