Description

  The present invention relates to a garbage drying processing machine for drying and reducing the amount of garbage generated in general households and food factories, restaurants, fast food stores and the like.

As a conventional apparatus for reducing or eliminating garbage, two methods are generally used for both home use and business use. The drying method (for example, see Patent Documents 1 and 2) has some heating means (combustion, electric heater, magnetron, etc.), and directly raises the temperature of the garbage in the drying container by indirect heating means. A method for evaporating the moisture of garbage, drying and reducing the weight is well known. In the case of this drying method, a method of drying in a drying container, taking out the container, transferring to another container (such as a garbage bag), and discarding is common. In addition, the method by the decomposition of microorganisms decomposes garbage by decomposing bacteria by placing a base material that becomes a fungus bed such as large sawdust in a treatment tank provided with stirring means and controlling it to an appropriate temperature and humidity. Methods for weight loss are well known.

  In most cases, such conventional drying-type garbage drying processors indirectly heat the garbage by heating means, so the heat transfer to the garbage is poor and the moisture in the garbage is reduced. In order to eliminate it to the outside, the heating means must supply a heat quantity that is more than the minimum heat energy required for evaporation of moisture. For this reason, the drying time has been extended and the amount of power consumption has increased. In addition, in order to throw in new garbage generated during the operation of the garbage processor, you may need to stop the processor once and start again from the beginning. When the input lid of the processing machine was opened in order to throw in the garbage during operation, the vapor and odor evaporated from the garbage were diffused to the surroundings, which made it uncomfortable.

  Therefore, the present invention solves such a conventional problem, and the garbage is dried in a short time with less energy (electricity bill), and the garbage is continuously produced at any time without waiting for the completion of the drying. An object of the present invention is to provide a garbage drying processing machine that can be charged and that does not emit steam or odor from the charging part.

  In order to solve the above-mentioned conventional problems, the garbage drying processing machine of the present invention is provided with a garbage input unit and a garbage pulverizing means below, pulverizes the input garbage, and then the garbage is rotated while rotating in parallel. There is a heat treatment part that heats and dries by heating means provided inside at least a pair of substantially cylindrical rollers while compressing and transporting the food, and further stores the garbage after the drying process (hereinafter referred to as treated waste) once below A removable discharge container is provided.

  With this configuration, the heating means heats the place where the compressed garbage is in the thinnest plate shape. When the garbage in this state is compressed, the moisture contained in the garbage is instantaneously expelled to the garbage surface, and the moisture can be directly heated by the heating means, so that the thermal efficiency is improved. In addition, since the garbage itself becomes thin, heat transfer is quick and the temperature of the garbage can be raised instantaneously. Therefore, the heat efficiency is good for the early drying time, and the power consumption can be kept low.

  In addition, the raw garbage input from the input section is sequentially sent to the heat treatment section, heated by a substantially cylindrical roller, and dried raw garbage is stored in the discharge container. Because it becomes possible to continuously put in and the garbage can be dried when garbage is generated, odor is generated from the garbage that has been stored in the kitchen, and its surroundings are soiled. In addition, it is possible to create a comfortable kitchen space without requiring a kitchen space for temporarily collecting garbage.

  Further, a partition device is provided in a passage between the pulverizing unit and the heat treatment unit, and a control unit is provided for controlling the partition device to be closed except at a predetermined time.

  Thereby, during operation, for example, raw garbage is thrown in and the crushed garbage is sent to the heat treatment unit and heated by the heating device to generate steam and odor, but the state does not always continue, heating means The temperature control works, the heating means is turned off, and there are times when steam and odor are not generated much. By providing a control means that can open the partition device only in such a state, even when the garbage drying processor is in operation, when the garbage is put into the input section, the steam generated in the drying processing section There is almost no odor coming into the input section. In this way, even when throwing in newly generated garbage during operation of the garbage drying processor, it is blocked from the heat treatment part by the partition device, so that unpleasant odors and vapors diffuse into the room and make it uncomfortable. Can be eliminated.

  The garbage drying processing machine of the present invention has good thermal efficiency for a short drying time, low power consumption, and can be input continuously at any time from the input unit. Even when newly generated garbage is thrown into the inside, there is an effect that it is possible to eliminate unpleasant odors and steam from being diffused into the room and making it uncomfortable.

  According to a first aspect of the present invention, there is provided a garbage input unit, a garbage crushing unit provided below the input unit, a pressure feeding unit comprising at least a pair of substantially cylindrical rollers below the garbage input unit, and the substantially cylindrical roller. A heating unit configured to heat the heating unit, and a discharge container for storing treated garbage disposed below the heating unit, and a partition device between the pulverizing unit and the heating unit. A control device for opening and closing the partition device is provided.

  As a result, during operation, steam and odor generated in the drying processing unit enters the charging unit by controlling the partition device to open only when the operating state is low in generation of steam and odor in the heat processing unit. It can be prevented from coming. And even when throwing away newly generated garbage during operation of the garbage processing machine, it is cut off from the heat treatment part by the partition device, so that unpleasant odors and vapors are not diffused into the room and made uncomfortable. Is something you can do.

  In a second aspect of the present invention, a partition device and a control unit that can be opened and closed only when the heating unit of the heat treatment unit is OFF are provided between the pulverization unit and the heat treatment unit. As a result, the partition device can be opened only in a state where there is little (or no) generation of steam or odor in the heat treatment section, so that almost no vapor or odor enters the charging section.

  In a third aspect of the present invention, a partition device that can be opened during operation of the pulverizing unit and its control unit are provided between the pulverizing unit and the heat treatment unit. As a result, the passage to the heat treatment section can be opened only when the pulverizing means is in operation, and the crushed garbage covers the passage while the pulverizing means is in operation, so that the steam from the heat treatment section It is possible to almost eliminate the entry of odors and odors.

  According to a fourth aspect of the present invention, there is provided a partition device and a control means that are interlocked with the opening and closing of the garbage input portion lid and are closed when the lid is opened. As a result, the partition device can always be closed when the garbage is put in. Therefore, the steam and odor from the heat treatment section are blocked, and the steam and odor leak into the room whenever the garbage is put in. There is nothing.

  According to a fifth aspect of the present invention, there is provided a lock unit that prevents the charging lid provided in the charging unit from being opened during operation of the pulverizing unit. Thereby, it becomes the structure which does not open a charging lid at the time of the operation | movement of the grinding | pulverization means which can open | release a partition apparatus, and it can prevent more reliably that a vapor | steam and odor leak into a room | chamber interior.

  In a sixth aspect of the invention, the partition device rotates coaxially with the rotating blades of the pulverizing means. As a result, the partition device can always partition the passage between the charging section and the heating processing section even when the pulverized garbage is sent to the heating processing section, thereby eliminating the entry of steam and odor from the heating processing section to the charging section. It is something that can be done.

  According to a seventh aspect of the present invention, the passage between the pulverizing means and the heat treatment unit has a trap structure, and a partition device that opens to the heat treatment unit side is provided therebetween. Thereby, the garbage crushed by the pulverizing means once accumulates at the bottom of the pulverizing means, and when it accumulates to some extent, the partition device provided in the trap structure part is pushed open by the force of the pulverizing means and falls to the heat treatment part. For this reason, even if a special drive device or control device is not provided, the charging unit and the heat treatment unit are closed except when the crushed garbage passes through the partition device, and steam and odors are input to the charging unit. Never enter. Further, when the crushed garbage is passing, the passage is blocked by the garbage, so that steam and odor do not enter the input part in the same manner.

  According to an eighth aspect of the present invention, there is provided a garbage input unit, a garbage pulverizing unit provided below the input unit, a pressure feeding unit formed of at least one pair of substantially cylindrical rollers below, and the substantially cylindrical roller. A heat treatment unit comprising heating means for heating, a discharge container for storing the treated garbage provided below the heat treatment unit, and an exhaust device for discharging steam generated in the heat treatment unit to the outside There is a passage, and further, a bypass passage that leads from this passage to the garbage input part is provided. During operation of the garbage processor, the exhaust system always sucks steam and odors, and after deodorizing, exhausts them outside the main body. By providing the bypass passage, the steam and odor that have entered the charging section can be sucked by the exhaust device, so that the steam and odor are not exhausted into the room whenever garbage is input. Further, when the charging lid of the charging unit is opened, the pressure loss of the charging unit is reduced and a large amount of outside air is sucked, so that no odor or vapor leaks from the charging unit.

  The ninth aspect of the invention is provided with a control means for increasing the capacity of the exhaust device when the lid is opened in conjunction with the opening and closing of the garbage input portion lid. As a result, when the charging lid of the charging unit is opened, a large amount of outside air is sucked, and odors and vapors are more reliably prevented from leaking from the charging unit.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a longitudinal sectional view of a garbage drying processing machine according to a first embodiment of the present invention.

  In FIG. 1, a lid 2 is provided on the upper part of the garbage drying processing machine main body 1, and a garbage input unit 4 for temporarily storing the garbage 3 is provided. A pulverizing means 6 for pulverizing the garbage 3 by the rotation of the rotary pulverizing blade 5 is provided below the garbage input unit 4. Below the crushing means 6, there is a heat treatment unit 7, which is arranged in parallel with a predetermined gap with a substantially cylindrical roller 8. The substantially cylindrical rollers 8 are driven to rotate in opposite directions. A scraper 9 for scraping the garbage 3 attached to the substantially cylindrical roller 8 is provided on the lower surface of the substantially cylindrical roller 8. Further, a heating means 10 for heating the garbage 3 is fixed inside the substantially cylindrical roller 8 and is fixed at a fixed position with respect to the substantially cylindrical roller 8. The substantially cylindrical roller 8 rotates, but the heating means 10 does not rotate and is fixed at a fixed position. The fixing position is fixed to the nearest portion 11 closest to the adjacent substantially cylindrical roller 8. Further, a discharge container 12 for temporarily storing and discarding the garbage 3 dried by the heating means 10 is provided below the discharge container 12. In addition, a partition device 14 is provided in the passage 13 between the charging unit 4 and the pulverizing means 6 and the drying processing unit 7, and includes a movable partition plate (opening / closing unit) 15, a rotating arm 16, and an actuator 17. The device (control means) 18 can be opened and closed. Further, an exhaust port 21 connected to the deodorizing device 19 and the exhaust device 20 is provided above the heat treatment unit 7. The overall operation control is performed by the control device 18.

  In the above configuration, the lid 2 is opened, the garbage 3 is put in, the crushing means 5 is rotated, and the operation of the substantially cylindrical roller 8 and the heating means 10 of the heat treatment unit 7 is started. The input garbage 3 is finely pulverized by the pulverizing rotor 5 of the pulverizing means 6. When the substantially cylindrical roller 8 reaches a sufficient temperature by the heating means 10, the controller 18 is controlled to open the partition device 14, and the actuator 17 rotates the rotary arm 16 to open the partition plate 14. As a result, the garbage 3 falls downward and is sequentially swallowed by the substantially cylindrical roller 8.

  At this time, the garbage 3 is compressed and rolled by the substantially cylindrical roller 8 and at the same time is immediately heated by the heating means 10 provided at this position, and is discharged as a dry thin plate-like dried garbage 3. It is sent to the container 12. At this time, the dry garbage 3 is scraped off by a scraper 9 urged by an elastic body or the like (not shown) so that the dried garbage 3 does not adhere to the substantially cylindrical roller 6. At this time, since the heating means 10 is always located at the position where the compression rolling is performed, the garbage 3 is heated by the heating means 10 in a thinly stretched state as described above, and heat transfer is fast and efficient. Garbage can be dried.

  At the same time, the moisture is mechanically squeezed out from the solid interior of the garbage 3 by compression rolling so that the moisture can be evaporated without transferring heat to the solid interior, so that the drying speed can be further increased. It has become. In addition, since the drying process can be performed sequentially even if the garbage is continuously added, the garbage can be input at any time, so that it is not necessary to secure a place for placing the garbage 3 in the kitchen. Furthermore, since the control device 18 can control the partition device 14 so that the partition device 14 is always closed when the garbage 3 is put in, it is heated even if the main lid 2 is opened during the treatment of the garbage 3. Steam and unpleasant odors during drying can diffuse into the room and eliminate unpleasant feelings.

  Further, in the present embodiment, the configuration in which the partition device 14 can be opened only when the heating means 10 is turned off by the control device 18, in particular, the generation of steam and odor in the heat treatment unit 7 is small ( Since the partition device 14 can be opened only in a state in which there is no or nothing), almost no vapor or odor enters the charging unit 4. Further, even when fresh garbage 3 is introduced and the partition plate 15 is opened by chance, since there is almost no generation of steam or odor, it hardly diffuses into the room.

  Furthermore, in the present embodiment, by providing a partition device 14 that can be opened by the control device 18 when the crushing means 6 is operated, the crushing means 6 opens the passage to the heat treatment unit 7. It is possible only during the operation, and when the pulverizing means 6 is in operation, the crushed garbage 3 is present and often covers the passage, so that almost no vapor or odor enters from the heat treatment unit 7. It is something that can be done.

  Further, in the present embodiment, the control device 18 is provided with means (not shown) for detecting the open / closed state of the main body cover 2 in conjunction with the opening / closing of the main body cover 2 and the partition device 14 that is closed when the cover is opened. Then, since the partition device 14 can always be in a closed state at any timing when the garbage 3 is put in, the steam and odor from the heat treatment unit 7 are shut off and the garbage 3 is thrown in at any time. However, steam and odor will not leak into the room.

(Embodiment 2)
FIG. 2 is a vertical cross-sectional view of a portion around the lid of the garbage input portion of the garbage drying processing machine according to the second embodiment of the present invention.

  In FIG. 2, a locking portion 22 is provided on the lid 2, and the locking portion 22 is operated by an operation of an actuator 23 and a locking arm 24 provided in the garbage drying processing machine main body 1 with the lid 2 closed. 2 can be locked. Accordingly, the control device 18 controls the lid 2 to be locked when the crushing means 6 is in operation, and the partition device 14 is not likely to be opened when the crushing means 6 is likely to be opened. Thus, it is possible to more reliably prevent vapor and odor from leaking into the room.

(Embodiment 3)
FIG. 3 is a longitudinal sectional view of a garbage drying processing machine according to the third embodiment of the present invention.

  In FIG. 3, there is a crushing means 6 at the bottom of the charging unit 4, and a semi-cylindrical rotating partition plate 25 that rotates coaxially with the rotary crushing blade 5 of the crushing means 6 is provided. Further, the rotary crushing blade 5 and the rotary partition plate 25 are not synchronized but are rotated by separate driving.

With the above configuration, the garbage 3 thrown into the charging unit 4 can be pulverized sufficiently finely by the rotary pulverization blade 5 because the rotary partition plate 25 is closed. When the rotating partition plate 25 is rotated 180 degrees in order to send the crushed garbage 3 to the heat treatment unit 7, the crushed garbage 3 falls to the lower heat treatment unit 7. Also at this time, the charging unit 4 is in a state of being partitioned by the rotary partition plate 25, so that the steam and odor of the heat treatment unit 7 hardly enter the charging unit 4 at all times. Further, since it can be introduced even during pulverization, the usability can be greatly improved.

(Embodiment 4)
FIG. 4 is a partial vertical cross-sectional view of the input part of the garbage drying processor in the fourth embodiment of the present invention.

  In FIG. 4, a passage connecting the charging unit 4 and the drying processing unit 7 is a trap structure 26, and a partition plate 27 is provided in the middle. The partition plate 27 is elastically pivoted and is configured to always block the passage. ing.

  With this configuration, the passage is normally blocked by the partition plate 27, and steam and odor do not enter the charging unit 4. When the garbage 3 is introduced, the garbage 3 is pulverized at the bottom of the input unit 4 by the rotation of the pulverizing means 6, and at the same time the partition plate 27 is pushed open to send the crushed garbage 3 to the drying processing unit 7. be able to. Since the garbage 3 is full when the partition plate 27 is opened, steam and odor do not enter from the drying processing unit 7 at this time. As a result, even if a special drive device is not required, the steam and odor can be blocked, and the garbage 3 can be diffused into the room any time and the uncomfortable feeling is eliminated.

(Embodiment 5)
FIG. 5 is a longitudinal sectional view of a garbage drying processing machine according to the fifth embodiment of the present invention.

  In FIG. 5, a bypass path 28 directly connected to the deodorizing device 19 and the exhaust device 20 is provided on the side wall of the charging unit 4.

  With this configuration, during operation of the garbage drying processor, steam and odor are always sucked by the exhaust device 20, and after the odor component is removed by the deodorizing device 21, the exhaust gas is exhausted outside the main body 1. By providing the bypass passage 28, the steam and odor that have entered the charging section 4 can be sucked by the exhaust device 20, so that the steam and odor are not discharged into the room whenever garbage is input. Further, when the charging lid 2 of the charging unit 4 is opened, the pressure loss on the charging unit 2 side is reduced and a large amount of outside air is sucked in, so that odors and vapors are hardly leaked from the charging unit.

  Further, in the present embodiment, a control means is provided that increases the ability of the exhaust device 20 when the lid is opened in conjunction with the opening and closing of the garbage input unit lid 2. As a result, when the charging lid 2 of the charging unit 4 is opened, a large amount of outside air is sucked, and odors and vapors are prevented from leaking from the charging unit 4 more reliably.

  As described above, the garbage drying processing machine according to the present invention dries the garbage in a short time and with a small amount of energy (electricity bill) and continuously collects the garbage at any time without waiting for the completion of drying. It is possible to use a garbage drying treatment machine that can be charged and does not emit steam or odors from the charging part, and it can dry foods that generate unpleasant odors other than household garbage. It can also be applied to machines.
