Description

Technical Field

[0005] ,

[0001] The present invention relates to a processing apparatus and a disposal method.

Background Art

[0002] In recent years, highly pathogenic avian influenza, which is thought to originate from migratory birds, etc., has been seasonally prevalent. Highly pathogenic avian influenza is designated as a livestock infectious disease, and livestock infected with this disease ("affected livestock", in the case of avian influenza, chickens, ducks, quails), and / or livestock suspected of being affected livestock ("suspected affected livestock") may be required to be culled by law. As a method of culling, in the case of chickens, the chickens housed in a feeding container (such as a cage) in a chicken farm are captured and taken out of the feeding container, and several chickens are housed in a plastic bag or the like, and the air in the plastic bag is replaced with carbon dioxide gas to asphyxiate the chickens in the plastic bag.

[0003] According to the Guidelines for the Prevention and Control of Specified Livestock Infectious Diseases published by the Ministry of Agriculture, Forestry and Fisheries, affected livestock and / or suspected affected livestock infected with a specific infectious disease need to be culled within 24 hours and the carcasses need to be incinerated or buried within 72 hours. Therefore, in order to perform this series of processes on hundreds of thousands to millions of chickens in a short period of time, a large-scale manpower approach is taken, and hundreds of people work continuously without rest. Since it is an urgent event, ensuring manpower for the large-scale manpower approach is also insufficient, and the current situation also depends on the support of various government agencies.

[0004] An example of a countermeasure law against such avian influenza damage is disclosed as a mobile vaporization device in Patent Document 1. In the device described in this publication, in order to achieve the effects of environmental protection, convenience, and prevention of infectious diseases, the mobile vaporization device has a movable carrier, a laser vaporization device, a gas treatment device, and a power supply device provided in the transport space of the carrier.

[0005] Here, the laser vaporization equipment performs laser vaporization on materials awaiting vaporization, the gas treatment device handles the intake and exhaust of gas to the laser vaporization equipment, and the power supply device stores and supplies the required electrical energy. When animal-borne infectious diseases such as avian influenza occur, the equipment can arrive quickly and agilely at the site and directly perform highly efficient work there.

[0006] Another example of disposing of livestock infected with infectious diseases is disclosed in Patent Document 2. The vehicle-mounted infectious animal rendering and processing device described in this publication moves livestock, especially livestock infected with infectious diseases, to a breeding facility and immediately sterilizes and disposes of them on the spot.

[0007] Specifically, the system is mounted on a trailer chassis that can be connected to a towing vehicle and includes a crusher for continuously crushing infected livestock, a heat sterilization container heated by a circulating electric heater heating device with an automatic temperature control function using oil as a heat transfer medium, a raw material pump screw and a first lamellar pump for transporting the animal bodies crushed by the crusher to the heat sterilization container, and a raw material transfer pipe connecting the first lamellar pump and the heat sterilization container. The second lamellar pump discharges the animal bodies after heat sterilization treatment from the heat sterilization container via a product discharge screw, and then transfers and fills them into a sealed metal container with a lid via a product pump supply screw and a product transfer pipe. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Utility Model Registration No. 3235222 Gazette [Patent Document 2] Japanese Patent Publication No. 2012-217629 [Overview of the project] [Problems that the invention aims to solve]

[0009] As mentioned above, outbreaks of livestock infectious diseases are sudden events, making it difficult to respond to them. The current manpower-intensive approach has limitations in the number of personnel that can be gathered, and the urgent need for response leads to longer working hours for workers. Furthermore, working while preventing secondary damage is increasing the health risks to the workers.

[0010] In the case described in Patent Document 1, a vehicle compartment is formed on the cargo bed of a truck or the like, and the entire compartment is used as a processing chamber to treat carbon dioxide gas. Because it is a vehicle-mounted processing device, it can be quickly dispatched to the scene of the outbreak, and because it is equipped with advanced scientific instruments such as a laser vaporizer and an image recognition device, it is capable of advanced processing.

[0011] However, if avian influenza occurs at a poultry farm or similar facility, and the number of infected and / or suspected infected animals (hereinafter also referred to as "infected animals, etc.") to be processed is large (for example, hundreds of thousands to millions of birds), one or two such advanced devices may be insufficient. Furthermore, in practical terms, capturing a large number of infected animals, etc. and housing them in the same processing room is time-consuming because they are living creatures that move around, making it difficult to capture them while avoiding secondary damage.

[0012] The livestock rendering apparatus described in Patent Document 2 crushes diseased livestock, and therefore appears to require a significant number of post-processing steps from the standpoint of preventing the spread of contamination. Furthermore, when processing a massive number of poultry, ranging from hundreds of thousands to millions of birds, improvements are desired in terms of the labor involved in capturing and collecting the target material and the simultaneous processing capacity.

[0013] This invention has been made in view of the shortcomings of the prior art described above, and aims to provide a highly durable processing device that can efficiently process a large number of sick animals and can be used repeatedly. Another objective is to provide a method for euthanizing sick animals using this processing device. [Means for solving the problem]

[Figure 13] This is a flowchart illustrating the procedure for using the processing device of the second embodiment (euthanasia method). [Modes for carrying out the invention]

[0030] Hereinafter, an embodiment of the processing apparatus and culling method according to the present invention will be described with reference to the drawings. In the following description, the infected animals will be chickens and the livestock infectious disease will be highly pathogenic avian influenza (simply referred to as "avian influenza"). However, the infected animals to which the processing apparatus and culling method of the present invention can be applied are not limited to these. Examples of infected animals include cattle, sheep, goats, pigs, horses, chickens, ducks, quail, and honeybees, among which chickens, ducks, quail, and pigs are preferred, and chickens and pigs are more preferred. Furthermore, examples of livestock infectious diseases include rinderpest, bovine pleuropneumonia, foot-and-mouth disease, epidemic encephalitis, rabies, vesicular stomatitis, Rift Valley fever, anthrax, hemorrhagic sepsis, brucellosis, tuberculosis, Johne's disease, piroplasmosis, anaplasmosis, infectious spongiform encephalopathy, bovine spongiform encephalopathy, glanders, equine infectious anemia, African horse plague, ruminant disease, classical swine fever, African swine fever, swine vesicle disease, poultry cholera, highly pathogenic avian influenza, low pathogenic avian influenza, Newcastle disease, poultry salmonellosis, and foulbrood, and the above-mentioned livestock infectious diseases can also be treated with this method.

[0031] Figure 1 shows a schematic perspective view of an example of a poultry farm 50. The poultry farm 50 has multiple chicken coops 10.

[0032] Although not shown in the diagram, the chicken coop 10 has multiple longitudinal aisles, and cage shelves with more than 100 rows of cages (an example of a breeding container) arranged in multiple tiers vertically are located on both sides of each aisle. Each cage houses one or more chickens, and the system is configured to automatically or manually supply the chickens with necessary supplies such as feed and water.

[0033] If an outbreak of avian influenza occurs at such a poultry farm 50, one or more processing units 100 are loaded onto a truck 30 and transported to a suitable location near the poultry farm 50 in order to cull chickens infected with avian influenza and chickens suspected of being infected.

[0034] A mobile crane 20 or a forklift 40 is prepared in advance at the poultry farm 50. In the case of the mobile crane 20, a (lifting) wire 26 is passed through a hook 24 attached to the tip of the boom 22 and connected to fixed lifting rings 102 provided at multiple locations on the upper end of the processing device 100, thereby allowing the mobile crane 20 to lift the processing device 100 from the truck bed 30 and install the processing device 100 in a suitable location. In this way, since the processing device 100 is equipped with fixed lifting rings 102, it can be easily transported and installed in a designated location by the crane.

[0035] Furthermore, if a forklift 40 is available, the forks 42 of the forklift 40 are inserted into the fork holes 104 provided in the base of the lower part of the processing device 100, the processing device 100 is lifted from the truck bed 30, and moved to a suitable location for installation. In this way, since the processing device 100 is equipped with fork holes 104, it is easy to move and install it in a predetermined location using a forklift. The fork holes 104 and the lifting ring 102 are examples of attachment devices for material handling machinery, and other attachment devices may also be provided. These attachment devices improve the portability of the processing device 100.

[0036] Here, since the number of birds to be treated at the 50 poultry farms where avian influenza has occurred ranges from several hundred thousand to several million, multiple processing units 100 are naturally required, and therefore the processing unit 100 is designed to be simple and inexpensive. In addition, since it is not used on a regular basis, it is sized to be easily transported by truck 30 from the designated storage location to the specified location.

[0037] [Configuration of the processing apparatus of the first embodiment] Figures 2, 3, and 4 are diagrams showing the details of the processing unit 100. Figure 2 is a plan view of the processing device 100, Figure 3 is a front view (open state) of the processing device 100, and Figure 4 is a perspective view showing the external appearance of the processing device 100. The processing device 100 mainly comprises a housing unit 101, an entrance / exit 120, and an inlet 130. The housing unit 101 is formed in a rectangular parallelepiped shape and comprises a base portion 110 at the bottom that bears the load inside the processing device 100 and has holes 104 for fork tines, a floor plate 140 that forms the upper surface of the base portion 110, side plates 150 erected at both left and right ends of the base portion 110, a back plate 160 erected at the rear end of the base portion 110, and a ceiling plate 170 provided at the upper ends of the side plates 150 and the back plate 160.

[0038] Furthermore, both side panels 150 and the back panel 160 can be constructed by using metal siding on the surface exposed to the outside (outer side) and arranging a water-resistant plate-shaped wooden member inside the containment unit 101 (inner side) to form the side walls. As will be described in detail later, the processing device 100 will be used repeatedly after the culling of infected animals, etc., so the processing device 100 needs to be washed and / or disinfected. For this reason, the processing device 100 needs to be water-resistant so that the inner and outer sides of the containment unit 101 do not rot or get damaged even after being washed and / or disinfected many times.

[0039] In this invention, water resistance means having the ability to withstand multiple washes and / or disinfections. Therefore, it is not necessary for it to be completely waterproof and impermeable to water, but it may be completely waterproof from the viewpoint of slowing down the deterioration of the treatment device 100.

[0040] Therefore, the treatment device 100 can be made water-resistant by using metal siding and / or a plate-shaped wood member that has been treated to be water-resistant, as described later.

[0041] The entrance / exit 120 includes a right door 120a and a left door 120b. As will be described in more detail later, the doors 120a and the left door 120b are integrally formed by using metal siding on the exterior side, placing a water-resistant wood component or plywood on the interior side, and then covering the water-resistant wood component from the interior side with metal siding.

[0042] As the board-shaped wood member, plywood with a thickness of 18 to 21 mm can be used. The plywood can be ordinary plywood, structural plywood, concrete formwork plywood, surface-treated concrete formwork plywood, decorative structural plywood, natural wood decorative plywood, or specially processed decorative plywood. Concrete formwork plywood is preferred from the viewpoint of water resistance and cost, but each type of plywood may be coated with a water-resistant paint before use. For concrete formwork plywood, resin-coated plywood is more preferable. Alternatively, MDF (Medium Density Fiberboard), particleboard, OSB (Oriented Strand Board), etc., may be used instead of plywood, or a single sheet of solid cedar wood may be used. In that case, water-resistant treatment such as resin coating is necessary. Hereinafter, board-shaped wood members that have undergone water-resistant treatment will be referred to as water-resistant wood members.

[0043] Examples of metal siding include aluminum-plated steel sheets, stainless steel sheets, tin-plated steel sheets, hot-dip galvanized steel sheets, electro-galvanized steel sheets, aluminum alloy-plated steel sheets, aluminum-zinc alloy-plated steel sheets, and steel sheets to which magnesium has been added for rust prevention.

[0044] Aluminum-plated steel sheets and stainless steel sheets are highly durable but difficult to install and expensive. Tin-plated steel sheets, hot-dip galvanized steel sheets, and electro-galvanized steel sheets have good water corrosion resistance and workability and are inexpensive, but they have low durability and are prone to rusting. For these reasons, aluminum-zinc alloy plated steel sheets and aluminum-zinc alloy plated steel sheets with added rust prevention properties from magnesium are preferred as metal siding materials because they have high corrosion resistance, waterproofing properties, strength, are lightweight and inexpensive.

[0045] To further enhance durability, resin paint may be applied to the metal siding. Alternatively, resin sheets or ceramic boards may be used instead of metal siding. Resin sheets are tough and inexpensive, but have poor weather resistance, such as being susceptible to UV degradation. Ceramic boards, on the other hand, are heat-resistant and corrosion-resistant, but are difficult to process and expensive. Therefore, it is preferable to use aluminum-zinc alloy plated steel sheets, or aluminum-zinc alloy plated steel sheets with magnesium added for rust prevention, rather than resin sheets or ceramic boards.

[0046] Since metal siding is water-resistant, using metal siding can result in a highly durable treatment device 100.

[0047] The ceiling panel 170 forming the roof has a plated or painted steel sheet on the outer side and a water-resistant wood material on the inner side. The floor panel 140 is also a water-resistant wood material. In other words, the side panels 150, back panel 160, ceiling panel 170, and floor panel 140 of the processing device 100 are all made of water-resistant wood material, so even if forklifts or workers access the interior, it is less likely to rot or deteriorate.

[0048] As described above, door fasteners 116 are attached to the front end surface of the ceiling panel 170 and the front end surface of the base portion 110. Fork claw holes 104 are formed in the base portion 110 at a position outside (side side) of the door fasteners 116. In this example, the fork claw holes 104 are provided on the front side, but depending on the relationship between the width W and depth L, the fork claw holes 104 may be provided on the side or the back side.

[0049] The right door 120a and the left door 120b are integrally formed when the entrance 120 is closed. The outer side (120c, 120d side) is made of metal siding, and the inner side (120a, 120b side) is made of water-resistant wood material. Furthermore, the water-resistant wood material is covered from the inner side with metal siding.

[0050] Since both sides of the right door 120a and the left door 120b are covered with metal siding, they have high water resistance, which helps to suppress corrosion and deterioration of the right door 120a and the left door 120b. Although a water-resistant resin paint could be applied instead of metal siding to the outer sides (120c and 120d sides) of both doors, it is preferable to use metal siding from the standpoint of durability and product liability law.

[0051] Through diligent research by the inventor, it has been found that the doors (120a and 120b) are more susceptible to moisture and scratches and more prone to deterioration than the storage unit 101. For this reason, it is preferable to cover both sides of the right door 120a and the left door 120b with metal siding.

[0052] Although not shown in the diagram, the water-resistant wooden components of the side panels 150, back panel 160, ceiling panel 170, and floor panel 140 can also be covered with metal siding from the inside. In this case, since the entire inside of the housing unit 101 is covered with metal siding, the corrosion and deterioration suppression effect of the processing device 100 will be better when loading and unloading gauges, when workers access the inside and damage the interior, or when cleaning the inside of the processing device 100 after use. From the viewpoint of cost reduction, the lower halves of the side panels 150 and back panel 160, and the floor panel 140 on the inside of the processing device 100, which are particularly susceptible to damage, may also be covered with metal siding.

[0053] The inlet 130 is a supply port for supplying a predetermined gas, such as carbon dioxide (CO2), to the inside of the containment unit 101 (a gas for euthanizing sick animals and / or suspected sick animals). As will be described in detail later, the inlet 130 is configured so that the air inside the containment unit 101 becomes nearly airtight when the predetermined gas is supplied into the containment unit 101.

[0054] The containment unit 101 should be large enough for quarantine personnel to enter inside. While not particularly limited in size, it may, for example, have a width W of slightly less than 2000 mm, a total height H including the base slightly more than 2100 mm, and a depth L of approximately 1800 mm to 4000 mm. Its weight may be approximately 500 kg to 1500 kg. One or more processing units 100 are loaded onto the truck, depending on its loading capacity.

[0055] The processing unit 100 is a movable storage unit or container-like structure, and it is desirable that the entrance / exit 120 be a double-hinged door (double door) that can be opened and closed, but it is not limited to this. Multiple hinges 114 are provided at vertical intervals on the right end of the right door 120a and on the left end of the left door 120b, and the doors are rotatable around the hinges 114.

[0056] Here, the entrance 120 is a double door that can be opened and closed, which is preferable because it allows for a wide opening and easy entry of a forklift. On the other hand, if an opening wide enough for a forklift to access the interior can be provided, a door other than a double door may be used.

[0057] The overall width of a forklift is about 1050 mm for smaller models, so it is desirable that the width of the entrance 120 be 1050 mm or more. Having an entrance 120 width of 1050 mm or more allows sick animals, along with their enclosures, to be moved and housed inside the containment unit 101, enabling the euthanasia of a large number of sick animals in a short time.

[0058] A door handle 112 is provided in the form of a vertically extending rod on the central side of the processing unit 100, above the entrance / exit 120. The upper and lower ends of the door handle 112 are fitted into door fasteners 116 attached to the storage unit 101 to prevent the right door 120a and the left door 120b from being left open.

[0059] The treatment device 100 is formed in a rectangular parallelepiped shape as a whole, with a canopy 172 extending slightly forward over the ceiling of the entrance 120. The canopy 172 is provided to prevent corrosion of the hinges 114 for opening and closing the door, the door handle 112, and the door fasteners 116, which are located on the front of the treatment device 100, by rain falling on the treatment device 100, which is installed outdoors.

[0060] Similarly, to reduce the risk of paint peeling off the roof surface of the treatment device 100 and corrosion of the roofing material due to wind and rain, the roof has a gentle slope from the center of the treatment device 100 toward both the left and right ends, preventing raindrops from accumulating on the roof. An inlet 130 for introducing carbon dioxide gas (CO2) into the containment unit 101 is provided above the right door 120a. The inlet 130 penetrates from the outside to the inside of the containment unit 101 through the right door 120a. In this example, the inlet 130 is provided on the right door 120a of the containment unit 101, but its position is not limited to this. For example, it may be provided on the left door 120b, on the side (side wall), or on the ceiling.

[0061] [Configuration of the processing apparatus in the second embodiment] Figures 5, 6, and 7 are diagrams showing details of the processing device 200. Figure 5 is a plan view of the processing device 200, Figure 6 is a front view (open state) of the processing device 200, and Figure 7 is a perspective view showing the external appearance of the processing device 200. The processing device 200 comprises a housing unit 201, a first entrance / exit 220, a second entrance / exit 222, and an inlet 130. The housing unit 201 is formed in a rectangular parallelepiped shape and comprises a base portion 210 at the bottom that bears the load inside the processing device 200 and has holes 204 for fork tines, a floor plate 240 that forms the upper surface of the base portion 210, side plates 250 erected at both left and right ends of the base portion 210, and a ceiling plate 270 provided at the upper ends of the side plates 250.

[0062] In Figure 7, the front side is the first entrance 220, and the rear side is the second entrance 222. Both side panels 250 can be constructed as side walls by using metal siding on the exterior side (outer surface) and placing water-resistant wood material on the interior side.

[0063] The first entrance / exit 220 (second entrance / exit 222) comprises a right door 220a (222a) and a left door 220b (222b). Similar to the first embodiment, the doors 220a (222a) and the left door 220b (222b) are integrally formed by using metal siding on the exterior side, placing a water-resistant wood member on the interior side, and then covering the water-resistant wood member from the interior side with metal siding. The metal siding and water-resistant wood member are the same as those used in the first embodiment.

[0064] The ceiling panel 270 forming the roof has a plated or painted steel sheet on the outer side and a water-resistant wood material on the inner side. The floor panel 240 is also a water-resistant wood material. In other words, the side panels 150, back panel 160, ceiling panel 170, and floor panel 140 of the processing device 100 are all made of water-resistant wood material, so even if forklifts or workers access the interior, it is less likely to rot or deteriorate.

[0065] As described above, door fasteners 216 are attached to the front end surface of the ceiling panel 270 and the front end surface of the base portion 210. Fork claw holes 204 are formed in the base portion 210 at a position outside (side side) of the door fasteners 216. In this example, the fork claw holes 204 are provided on the front side, but depending on the relationship between the width W and depth L, the fork claw holes 204 may be provided on the side or the back side.

[0066] The right door 220a (222a) and the left door 120b (222b) are integrally formed when the first entrance 220 and the second entrance 222 are closed. The exterior side is made of metal siding, the interior side is made of water-resistant wood material or plywood, and the water-resistant wood material is further covered from the interior side with metal siding.

[0067] The right door 220a (222a) and the left door 120b (222b) are covered on both sides with metal siding, providing high water resistance and suppressing corrosion and deterioration of the right door 220a (222a) and the left door 120b (222b). While it is possible to apply a water-resistant resin paint instead of metal siding to the outer surfaces (120c and 120d sides) of both doors, using metal siding is preferable from the standpoint of durability and product liability law.

[0068] Although not shown in the diagram, the water-resistant wooden components of the side panels 250, ceiling panels 270, and floor panels 240 can also be covered with metal siding from the inside. In this case, the procedure is the same as in the first embodiment, so a detailed explanation is omitted. The containment unit 201 should be large enough for quarantine personnel to enter. Its size is the same as that of the processing device in the first embodiment, so a detailed explanation is omitted.

[0069] A first entrance / exit 220 is formed on one side (side wall) of the containment unit 201 for the entry and exit of quarantine personnel, etc. A second entrance / exit 222 is formed on the opposite side. The sizes of the first entrance / exit 220 and the second entrance / exit 222 may be the same or different. On the other hand, it is preferable that the openings be large enough to accommodate quarantine personnel and forklifts loaded with cages, etc.

[0070] The processing unit 200 is a movable storage unit or container-like structure, and the first entrance 220 and the second entrance 222 are double doors that can be opened and closed. The right door 220a of the first entrance 220 has multiple hinges 214 spaced vertically at the right end, and the left door 220b has multiple hinges 214 spaced vertically at the left end, and the doors can rotate around the hinges 214. The right door 222a and the left door 222b of the second entrance 222 are the same as described above.

[0071] Here, the first entrance 220 and the second entrance 222 are double doors that can be opened and closed, which is preferable because it allows for a wide opening and easy entry of a forklift. On the other hand, if an opening wide enough for a forklift to access the interior can be provided, other types of doors can be used.

[0072] The overall width of a forklift is about 1050 mm for smaller ones, so it is desirable that the width of the first entrance 220 and the second entrance 222 be 1050 mm or more. By having the width of the first entrance 220 and the second entrance 222 be 1050 mm or more, sick animals can be moved and housed inside the containment unit 201 along with their feeding containers, allowing for the euthanasia of a large number of sick animals in a short time.

[0073] On the central side of the processing unit 200, above the first entrance 220 and the second entrance 222 (not shown in Figure 2 as it is on the back side), a door handle 212 is provided in the form of a vertically extending rod. The upper and lower ends of the door handle 212 are fitted into door fasteners 116 attached to the housing unit 201 to prevent the right door 220a (222a) and the left door 220b (222b) from being left open.

[0074] The treatment device 200 is formed in a rectangular parallelepiped shape as a whole, with canopies 272 extending slightly forward over the ceilings of the first entrance 220 and the second entrance 222. The canopies 172 are provided to prevent corrosion of the hinges 214 for opening and closing the door, the door handle 212, and the door fasteners 216, which are located on the front of the treatment device 200, by rain falling on the treatment device 200, which is installed outdoors.

[0075] Similarly, to reduce the peeling of paint on the roof surface of the treatment device 200 and the corrosion of the roofing material due to wind and rain, the roof has a gentle slope from the center of the treatment device 200 toward both the left and right ends, preventing raindrops from accumulating on the roof. An inlet 130 for introducing carbon dioxide gas (CO2) into the containment unit 201 is provided at the top of the side wall.

[0076] The inlet 130 penetrates the outside and inside of the housing unit 201 in the side wall. In this example, the inlet 130 is provided on the side (side wall) of the housing unit 201, but its position is not limited to this. For example, it may be provided on the right door 220a (222a), the left door 120b (222b), or on the ceiling. By providing the inlet 130 on the side or ceiling, i.e., in a part other than the door, it is easier to make it more robust (because it is not a movable part) even when a tube or the like is connected to the inlet 130.

[0077] [Configuration of the entry point] Next, Figure 8 shows the details of the inlet 130 provided in the housing units 101 and 201. Figure 8(a) is a front view of the inlet 130, Figure 8(b) is a longitudinal cross-sectional view of the inlet 130, and Figure 8(c) is a schematic diagram of the gas supply unit. The inlet 130 is composed of a stopper member 132 and a fin portion 134. The circular stopper member 132, made of soft rubber, is fitted into the openings formed in the housing units 101 and 201.

[0078] The stopper member 132 has a thin membrane on its outer surface, and the membrane has a plurality of slits 136 extending radially outward from the center. As a result, a plurality of fan-shaped fins 134 are formed on the membrane. On the back side of the membrane (inside the housing units 101 and 201) there is a cylindrical fitting portion that fits airtightly into the openings of the housing units 101 and 201. A retaining mechanism is formed on the back side of the fitting portion. If the fitting portion has virtually no gap in the radial direction, the retaining mechanism is not necessary.

[0079] The gas supply unit is a component for introducing carbon dioxide gas into the containment units 101 and 201 via the inlet 130. The gas supply unit comprises a gas supply source 900, a tube 902, and a valve 904. The tube 902, made of resin or metal, is fitted into the stopper member 132 and extends inside the processing unit 100 to the vicinity of the ceiling plate 170.

[0080] Figure 9 shows an image of the mounting jig 301 for fixing the tube, which is fixed to the ceiling of the housing units 101 and 201. The carbon dioxide gas ejection part 300, which is fixed to the tip of the tube 902, is fixed to the frame material of the processing equipment 100 and 200, which are installed between the ceiling panels 170, using the mounting jig 301.

[0081] The mounting jig 301 comprises a fixing device 302 fixed to the framework material of the ceiling portion of the processing devices 100 and 200, and an inserting device 303 fixed to the ejection unit 300 and inserted into the fixing device 302 to fix the ejection unit and the fixing device 302. In this way, fixing is easy as the inserting device 303 can be inserted into the fixing device 302, and the fixing device 302 can be installed in various locations and multiple devices can be installed easily, so the ejection unit 300 can be easily fixed in various locations.

[0082] In this example, the ejection unit 300 is fixed inside the housing units 101 and 201 of the processing devices 100 and 200 using the mounting jig 301 with the configuration described above. However, various other fixing methods can be used to fix the ejection unit 300. Furthermore, if the ejection unit 300 is not fixed, the ejection unit 300 and the tube 902 will move violently when carbon dioxide gas is ejected, so it is desirable that the ejection unit 300 be fixed.

[0083] Here, the stopper member 132 through which the tube 902 is inserted has its fin portion (leak-preventing packing) 134 deformed to fit tightly in the direction of insertion of the tube 902 due to the insertion force, thus maintaining an airtight seal between the tube 902 and the stopper member 132. In Figure 9, the tube 902 is inserted from the inside to the outside of the processing devices 100 and 200, but it goes without saying that the reverse is also possible.

[0084] In that case, the fin portion 134 deforms toward the inside of the processing devices 100 and 200, but airtightness is maintained because the fin portion 134 is tightly sealed between the tube 902 and the stopper member 132.

[0085] The gas introduced into the processing units 100 and 200 is carbon dioxide gas, which is supplied from the gas supply source 900 to the tube 902 via the valve 904. Once a predetermined amount of cages has been brought into the processing units 100 and 200, all inlets and outlets are closed, and the valve 904 is operated to supply carbon dioxide gas from the gas supply source 900 to the tube 902.

[0086] Generally, carbon dioxide gas is frequently used for euthanizing sick and / or suspected sick animals due to cost considerations. In this example, carbon dioxide gas is also used, but it is not limited to carbon dioxide gas; other gases such as nitrogen gas may also be used, as long as they are effective in euthanizing sick and / or suspected sick animals.

[0087] Once a predetermined amount of gas, or the gas concentration in the treatment devices 100 and 200, has been supplied (filled into the treatment devices 100 and 200) for a predetermined time, the valve 904 is operated again to stop the supply of carbon dioxide gas, and a predetermined time is waited. After that, the cages are removed from the treatment devices 100 and 200, the infected animals inside the cages are collected, and sent to the next process. The loading and unloading of infected animals into and out of the treatment devices 100 and 200 may be done manually (by disease control personnel), but it is preferable to use a forklift or similar equipment to minimize contamination with people (disease control personnel) in order to prevent infection of infectious diseases through close contact with infected animals.

[0088] Since the installation locations for the treatment devices 100 and 200 are either outdoors with no nearby houses or other buildings, a small amount of carbon dioxide gas leakage is not a problem. Furthermore, the present invention incorporates additional measures to ensure the airtightness of the treatment device 100.

[0089] The treatment devices 100 and 200, originally intended for storage, can be repurposed for avian influenza treatment. However, while the original storage devices can be used as is, improving airtightness will further enhance work efficiency. Generally, when used as storage, if the interior is airtight, mold and other growths can occur if moisture or humidity accumulates inside. Therefore, ventilation is ensured while preventing theft and other issues.

[0090] Therefore, in this invention, in order to ensure airtightness, the airtight sealing means shown in Figure 10 are installed inside the processing devices 100 and 200. Figures 10(a) and (b) show details of the sealing member 124, which is a rubber packing attached to the periphery of the left door 120b, in a perspective view (Figure 10(a)) and an AA cross-sectional view (Figure 10(b)). Although the drawings show the left door 120b of the entrance / exit 120, the same applies to the right door 120a of the entrance / exit 120, the right door 220a and left door 220b of the first entrance / exit 220, and the right door 222a and left door 222b of the second entrance / exit 222.

[0091] The front (exterior) and interior (interior) sides of the left door 120b of the entrance 120, which are exposed to wind and rain, are made of metal siding 121a and 121c, providing a structure that enhances aesthetics, weather resistance, and water resistance. Plywood 121b can be used as the core material for the left door 120b to reduce weight. To further enhance water resistance, plywood 121b may be made of water-resistant wood.

[0092] When moisture penetrates the plywood 121b during cleaning or rain, it can cause the door to corrode and deteriorate. Therefore, sealing material (caulking material) is applied to form a sealed section 125, which can prevent the door from rotting or deteriorating. Any type of sealing material can be used, including silicone-based sealing materials or modified silicone-based sealing materials that have excellent weather resistance, water resistance, and heat resistance.

[0093] The sealing member 124, positioned around the four perimeters (entire circumference) of the left door 120b, is made of rubber or synthetic resin and comprises a door holding portion 124a that overlaps the surface side of the metal siding 121a, a door holding portion 124d that overlaps the surface side of the plywood 121b, a door thickness portion 124e that is formed to fit into the left door 120b together with the door holding portions 124a and 124d and extends in the thickness direction of the left door 120b, a sealing reinforcement portion 124c that extends upward from the door holding portion 124d on the plywood side, and a sealing surface forming portion 124b that extends upward from the door holding portion 124a on the steel plate side and is ultimately bent to form the appearance of the sealing member 124. The sealing surface forming portion 124b adheres tightly to the front opening (door closing opening) of the processing device 100, thereby maintaining the airtightness of the processing device 100 and making it possible to create a sealed space inside the processing device 100.

[0094] Furthermore, as shown in Figure 10(c), a caulking material such as silicone rubber is applied to the joints or connections between the steel frame material and the water-resistant wood material, and between the water-resistant wood material, on the inner surfaces of the processing devices 100 and 200 to form a caulking processing area 180, thereby sealing the processing devices 100 and 200.

[0095] However, it is not made completely airtight. If it were completely airtight, the internal pressure would increase when carbon dioxide gas is introduced, which would be dangerous. Therefore, it is desirable to have an airtightness that does not cause an increase in internal pressure when carbon dioxide gas is introduced.

[0096] Figure 10(d) is a view of the sealing member 124 of the door 120b from the outside. Corner brackets 126 made of aluminum or stainless steel are fixed to the joint portion between the sealing members 124. The corner brackets 126 protect the joint portion between the sealing members 124, making it more difficult for the sealing members 124 to peel off the door 120b. The corner brackets 126 do not have to be installed, but it is preferable to install them from the viewpoint of durability of the sealing member 124 and airtightness provided by the sealing member 124 to the processing device 100(200). Furthermore, it is preferable to use a material with high water resistance and weather resistance for the corner brackets 126, but it is not limited to this.

[0097] [Means of improving portability] Next, the means attached to improve the portability of the processing apparatus 100 and 200 according to the present invention will be described. Here, the processing apparatus 100 will be described, but the same applies to the processing apparatus 200. First, the base portion 110 of the processing apparatus 100 has fork claw holes 104 on its side. Fork claw holes 104 are provided on both sides.

[0098] Figure 11 is a side view of the suspension ring 102. Normally, eyebolt holes are provided in the roof section, but in order to ensure the airtightness of the roof and prevent rainwater from entering through the eyebolt holes, in this invention, a substantially rectangular suspension ring 102 with openings 102b is welded 98 to the front and rear ends of the top side of the processing device 100. Because it is fixed by welding, corrosion of components located near the suspension ring 102, such as hinges, caused by eyebolt holes is reduced.

[0099] [Procedure for using the processing apparatus of the first embodiment] Next, we will explain how to use the processing device 100 (euthanasia method). Figure 12 is a flowchart showing the procedure for using the processing device 100 (euthanasia method).

[0100] First, in step S101, the doors of the entrance / exit 120 (right door 120a, left door 120b) are opened, and the infected animals are brought into the inside of the processing unit 100 (inside the containment unit 101). The infected animals brought in may be in a housing container. The containment unit 101 of the processing unit 100 of the present invention is sized so that disease control personnel can enter inside, so if the infected animals are chickens, quail, ducks, etc., they can be easily housed in cages, which are common housing containers.

[0101] Traditionally, a method was sometimes employed in which infected animals (such as chickens) removed from cages were placed in plastic bags, buckets, or pails, and then suffocated by gas. In this case, disease control personnel were divided into teams: those who removed the infected animals from the cages, those who placed them in plastic bags or buckets, and those who removed the suffocated animals from the plastic bags or buckets and packaged them for transport to processing facilities (such as melting and incineration facilities). Of these tasks, removing the infected animals from the cages was particularly difficult and sometimes became the rate-limiting step of the entire operation. One reason for this was that some of the infected animals, while treated as suspected cases, were not actually infected with livestock infectious diseases. Because these animals were, so to speak, "healthy," they often struggled violently when disease control personnel unfamiliar with handling livestock tried to remove them from the cages. In such cases, the entire operation could be delayed. Furthermore, even with protective measures in place, accidents could still occur in which disease control personnel were exposed to infected animals.

[0102] In the processing apparatus 100 of the present invention, sick animals can be transported directly to the containment unit 101 without being removed from cages or other breeding containers, thus preventing the aforementioned accidents and significantly improving work efficiency.

[0103] Next, in step S102, the doors of the entrance / exit 120 (right door 120a, left door 120b) are closed and gas (carbon dioxide gas) is introduced into the processing device 100. The carbon dioxide gas should be introduced from the gas supply unit described above according to predetermined conditions. These conditions may include, for example, the gas supply time and the cumulative supply amount.

[0104] Furthermore, the supply of gas from the gas supply unit may be performed manually by an operator (epidemic prevention officer). In this case, the gas supply unit should be activated after confirming that the inlet / outlet 120 is closed. If the inlet / outlet 120 is equipped with a sensor that detects a closed state, the gas supply unit may be configured to automatically supply gas according to predetermined conditions once the sensor detects a closed state. In other words, the gas supply may be automatically started using the detection of a closed state as a trigger.

[0105] If the entrance / exit 120 is equipped with a sensor that detects when it is closed, it can also be configured to generate an alert if an attempt is made to start supplying gas from the gas supply unit when the door is not detected as closed (the door is open). This helps to suppress unnecessary gas supply and also helps to prevent accidents. Next, in step S103, the doors of the entrance / exit 120 (right door 120a, left door 120b) are opened, and the infected animals are removed from the processing device 100.

[0106] Next, as step S104, the inside of the processing unit 100 is cleaned and / or disinfected. During culling in response to outbreaks of livestock infectious diseases, the inside of the processing unit 100 may become contaminated by the scattering of feces, urine, blood, etc., of infected animals, or, in the case of birds, by the laying of eggs. The processing unit 100 is used repeatedly to dispose of multiple infected animals. If it is used while contaminated, there is a risk of accidents such as disease control personnel being exposed to infected animals, or the possibility of spreading viruses to uninfected livestock when moving the processing unit 100 after one use to another site of a specific livestock infectious disease outbreak. Therefore, when contaminated, the inside of the processing unit 100 must be cleaned and / or disinfected. In this embodiment, step S104 is performed after step S103, but it may be omitted as appropriate depending on the degree of contamination inside the processing unit 100. However, once all culling work is completed, it is necessary to perform S104 in order to safely store the processing unit 100 until the next use. In that case, it is recommended to thoroughly dry the inside of the processing unit 100 before storing it.

[0107] [Procedure for using the processing apparatus of the second embodiment] Next, we will explain how to use the processing device 200 (euthanasia method). Figure 13 is a flowchart showing the procedure for using the processing device 200 (euthanasia method).

[0108] First, in step S201, the doors of the first entrance / exit 220 (right door 220a, left door 220b) are opened, and the sick animals are brought into the inside of the processing unit 200 (inside the containment unit 201). The sick animals brought in are the same as those in the processing unit 100 of the first embodiment, so no further explanation is given.

[0109] One of the features of the culling of diseased animals using the processing device 200 of the present invention is that the flow of movement of disease control personnel and others is taken into consideration, making it more efficient. This is because the containment unit 201 is equipped with two airtight, closable entrances and exits facing each other, and the inside of the containment unit 201 can be made "one-way".

[0110] First, in this step (step S201), the sick animal is brought in from the first entrance / exit 220 side. In this example, it is the first entrance / exit 220 side, but it may also be the second entrance / exit 222 side. In any case, one of the two sides is used as the entrance for bringing in the sick animal.

[0111] Next, in step S202, the doors of the first inlet / outlet 220 (right door 220a, left door 220b) are closed, and gas (carbon dioxide gas) is introduced into the processing device 200. At this time, the doors of the second inlet / outlet 222 (right door 222a, left door 222b) are also closed. The carbon dioxide gas and gas supply are the same as in the processing device 100 of the first embodiment, so the explanation is omitted.

[0112] Next, in step S203, the doors of the second entrance / exit 222 (right door 222a, left door 222b) are opened, and the infected animals are removed from the processing device 200. At this time, the exit is the entrance / exit located on the side opposite to the entrance. That is, if the first entrance / exit 220 is the entrance, then the second entrance / exit 222 is the exit. In this way, the infected animals inside the processing device 200 will move in one direction.

[0113] As mentioned above, culling due to outbreaks of infectious diseases in livestock occurs suddenly and requires action within a limited timeframe. Therefore, it must be carried out all at once by mobilizing a large number of disease control personnel. These disease control personnel are not necessarily all specially trained (e.g., livestock disease control officers), but the majority are general administrative staff. In order to efficiently carry out the work by dividing these personnel into teams, it is preferable to divide them into teams: one team to remove infected animals in their containers and place them in the processing unit 200, and another team to remove infected animals that have been suffocated in their containers. In this case, by providing two or more entrances and exits to the processing unit 200, personnel from each team can be stationed in front of each entrance and exit, and the processing can be carried out one after another in a bucket brigade manner, making more effective use of space and time.

[0114] Next, in step S204, the doors of the first entrance / exit 220 (right door 220a, left door 220b) are opened again, and new sick animals are brought into the processing unit 200. In this example, steps S203 and S204 are performed sequentially, but these steps may be performed simultaneously. Since the processing unit 200 of the present invention has entrances / exits on opposite side walls, even if both entrances / exits are opened, the person in charge of removal and the person in charge of receiving are waiting in front of their respective assigned entrances / exits, so there is no confusion. Also, within the containment unit 201, sick animals move in one direction, so there is no interference.

[0115] After step S204 is completed, return to step S202 and repeat the procedures from S202 to S204 until all infected animals and suspected infected animals have been euthanized.

[0116] Next, the inside of the processing device 200 is cleaned and / or disinfected, similar to step S104. The cleaning method and other details are the same as those of the processing device 100 in the first embodiment, so the explanation is omitted. Note that S104 is performed after all infected animals have been euthanized, but it may also be performed between S203 and S204 depending on the degree of contamination inside the processing device 200.

[0117] As described above, according to this embodiment, the processing device is portable, making it possible to transport infected animals in cages into the processing device and process a large number of animals simultaneously. This prevents secondary contamination and allows for processing with fewer personnel than currently possible. Furthermore, by making the door water-resistant and / or improving the durability of the sealing member, it is possible to provide a processing device that is less prone to deterioration and has superior durability compared to conventional processing devices.
