Description

[Technical Field]

[0001] The present invention relates to a processing device and a culling method. [Background technology]

[0002] In recent years, there have been seasonal outbreaks of highly pathogenic avian influenza, which is thought to have originated from migratory birds. Highly pathogenic avian influenza is designated as a livestock infectious disease, and infected livestock ("sick animals"; in the case of avian influenza, this means chickens, ducks, and quails) and / or livestock suspected of being sick ("suspected sick animals") may be required to be culled by law. In the case of chickens, the culling method has been to capture chickens housed in containers (cages, etc.) at poultry farms, remove them from the containers, and place several of them in plastic bags, etc., and then replace the air in the bags with carbon dioxide gas to suffocate the chickens inside the bags.

[0003] To carry out this series of processes on hundreds of thousands to millions of chickens in a short period of time, a human wave tactic is being used, with hundreds of people working nonstop. Because this is a sudden event, it is difficult to secure the necessary personnel, and the current situation is somewhat dependent on support from various government agencies.

[0004] An example of a countermeasure against such damage caused by avian influenza is disclosed in Patent Document 1 as a mobile photovoltaic device. In order to achieve the combined effects of environmental protection, convenience, and infection prevention, the device described in this publication includes a mobile carrier, and a laser vaporizer, gas processing device, and power supply device that are installed within the carrier's transport space.

[0005] The laser vaporization equipment performs the laser vaporization work for the waiting materials, the gas treatment equipment takes in and exhausts the gas for the laser vaporization equipment, and the power supply equipment stores and supplies the required electrical energy.When an animal-borne infectious disease such as avian influenza occurs, it can arrive at the scene quickly and flexibly and carry out the work directly on site with high efficiency.

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

[0007] That is, mounted on a trailer chassis that can be connected to a towing vehicle is a crusher that continuously crushes infected livestock, a heat sterilization container that is circulated and heated by an electric heater heating device with an automatic temperature control function that uses oil as a heat medium, a raw material pump screw and a first lamellar pump that transport the livestock crushed by the crusher to the heat sterilization container, and a raw material transfer pipe that connects the first lamellar pump and the heat sterilization container, and the livestock that have been heat sterilized by the second lamellar pump are transported from the heat sterilization container by a product discharge screw and transferred and filled into a sealed metal container with a lid via the product pump supply screw and product transfer pipe.

[0008] [Patent Document 1] Utility Model Registration No. 3235222 [Patent Document 2] Japanese Patent Application Laid-Open No. 2012-217629 Summary of the Invention [Problem to be solved by the invention]

[0009] As mentioned above, outbreaks of livestock infectious diseases are sudden events, making it difficult to respond to them. With the current human wave tactics, there is a limit to the number of people that can be gathered, and the need for an immediate response means that workers have to work long hours, and working while preventing secondary damage increases the damage to workers' health.

[0010] Patent Document 1 describes a vehicle compartment formed on the bed of a truck or the like, where the entire vehicle compartment is used as a treatment chamber and carbon dioxide gas is treated within the treatment chamber.As this is an on-board treatment device, it can be quickly dispatched to the site of an outbreak, and as it is equipped with advanced scientific equipment such as a laser vaporization device and an image recognition device, advanced treatment is possible.

[0011] However, if avian influenza breaks out at a poultry farm, etc., and there are a large number of sick and / or suspected sick animals (hereinafter also referred to as "sick animals, etc.") to process (for example, hundreds of thousands to millions of birds), one or two such advanced devices may not be enough. Furthermore, in practice, capturing a large number of sick animals, etc. and storing them in the same processing room requires a great deal of time, as they are living creatures that move around and need to be captured while avoiding secondary damage.

[0012] The livestock rendering treatment device described in Patent Document 2 crushes diseased livestock to process them, and therefore is likely to require a large number of post-processing steps from the perspective of preventing the spread of contamination. Furthermore, when processing huge quantities of farmed chickens, ranging from hundreds of thousands to millions, improvements are desired in terms of the labor required to capture and collect the objects and the simultaneous processing capacity.

[0013] The present invention has been made in consideration of the above-mentioned drawbacks of the prior art, and aims to provide a treatment device capable of efficiently mass-treating many sick animals, etc. It is also an object of the present invention to provide a method for culling sick animals, etc. using this treatment device. [Means for solving the problem]

[0017] An embodiment of the treatment device and culling method according to the present invention will be described below with reference to the drawings. In the following, the case will be described in which the affected livestock are chickens and the livestock infectious disease is highly pathogenic avian influenza (simply referred to as "avian influenza"). However, the affected livestock to which the treatment device and culling method of the present invention can be applied are not limited to this. Examples of affected livestock include cattle, sheep, goats, pigs, horses, chickens, ducks, quail, and honeybees, with chickens, ducks, and quail being preferred, and chickens being more preferred. Examples of livestock infectious diseases include rinderpest, bovine pleuropneumonia, foot-and-mouth disease, epidemic encephalitis, rabies, vesicular stomatitis, Rift Valley fever, anthrax, hemorrhagic septicemia, brucellosis, tuberculosis, Johne's disease, piroplasmosis, anaplasmosis, transmissible spongiform encephalopathy, glanders, equine infectious anemia, African horse sickness, peste des petit ruminants, swine fever, African swine fever, swine vesicular disease, fowl cholera, highly pathogenic avian influenza, low pathogenic avian influenza, Newcastle disease, poultry salmonellosis, and maggot rot, with fowl cholera, highly pathogenic avian influenza, low pathogenic avian influenza, Newcastle disease, and poultry salmonellosis being preferred, and highly pathogenic avian influenza and low pathogenic avian influenza being preferred.

[0018] 1 is a schematic perspective view of a poultry farm 50. A plurality of poultry houses 10 are built in the poultry farm 50.

[0019] Although not shown in the figure, there are multiple longitudinal aisles inside the poultry house 10, and cage shelves with over 100 rows of cages (an example of rearing containers) arranged vertically in multiple tiers are located on both sides of each aisle. Each cage houses one chicken, and is configured so that feed, water, and other necessities for the chickens are supplied automatically or manually.

[0020] Once avian influenza breaks out at such a poultry farm 50, one or more processing devices 100 are loaded onto a truck 30 and transported to an appropriate location near the poultry farm 50 to cull chickens infected with avian influenza and chickens suspected of being infected.

[0021] Mobile crane 20 or forklift 40 is prepared in advance at poultry farm 50. In the case of mobile crane 20, (hoisting) wire 26 is passed through hook 24 attached to the tip of boom 22 and connected to fixed hoisting rings 102 attached to multiple locations on the upper end of processing equipment 100, allowing mobile crane 20 to hoist processing equipment 100 from the bed of truck 30 and set processing equipment 100 in an appropriate location. In this way, since processing equipment 100 is provided with fixed hoisting rings 102, it can be easily transported to a desired location by crane and set up.

[0022] Furthermore, if a forklift 40 is available, the forklift 40's tines 42 are inserted into the fork claw holes 104 provided in the base of the lower portion of the processing device 100, and the processing device 100 is lifted from the bed of the truck 30, moved to a suitable location, and set up. The provision of the fork claw holes 104 thus makes it easy to move and set up the processing device 100 to a desired location using a forklift. The fork claw holes 104 and the hanging rings 102 are examples of attachments provided by the loading machine, and other attachments may also be provided. These attachments improve the portability of the processing device 100.

[0023] Here, the number of birds to be processed at poultry farm 50 where avian influenza has occurred ranges from hundreds of thousands to millions, so naturally multiple processing devices 100 are required, and for this reason processing devices 100 are simply and inexpensively constructed. At the same time, since they are not normally used, they are sized to be easily transported by truck 30 from the designated storage location to the designated location.

[0024] 2, 3A, and 3B are diagrams showing details of the processing apparatus 100. FIG.

[0025] The treatment device 100 includes a container-shaped storage unit 101. The storage unit 101 is large enough for a quarantine officer to enter inside. There are no particular limitations on the size, but it can have a width W of just under 2000 mm, a total height H including the base of just over 2100 mm, and a depth L of approximately 1800 mm to 4000 mm. The weight is approximately 500 kg to 1500 kg. One or more treatment devices 100 are loaded onto a truck depending on its load capacity.

[0026] A first entrance / exit 120 for quarantine personnel and the like to enter and exit is formed on one side surface (side wall) of the accommodation unit 101. A second entrance / exit 122 is formed on the opposite side. The first entrance / exit 120 and the second entrance / exit 122 may be the same size or different sizes. However, it is preferable that the opening be large enough to accommodate quarantine personnel and forklifts loaded with cages and the like.

[0027] The processing device 100 is similar to a portable storage shed or container, and the first entrance 120 and the second entrance 122 are double doors (double doors) that can be opened and closed freely. The right door 120a of the first entrance 120 is provided at the right end, and the left door 120b is provided at the left end, with multiple hinges 114 spaced apart in the vertical direction, and the doors can rotate around the hinges 114. The right door 122a and left door 122b of the second entrance 122 are similar to those described above.

[0028] Here, the first entrance 120 and the second entrance 122 are double doors that can be opened and closed freely, which is preferable in that the opening is wide and it is easy for a forklift to enter. On the other hand, doors other than double doors can also be used as long as the opening is wide enough to allow a forklift to access the interior.

[0029] The overall width of even the smallest forklifts is about 1050 mm, so it is desirable that the width of the first entrance 120 and the second entrance 122 be 1050 mm or more. By making the width of the first entrance 120 and the second entrance 122 1050 mm or more, sick animals and the like can be moved and housed inside the housing unit 101 together with their feeding containers, making it possible to cull a large number of sick animals and the like in a short period of time.

[0030] Door handles 112 are provided in the form of rods extending up and down above the first entrance 120 and the second entrance 122 (not shown in FIG. 2 because they are on the back side) at the center of the processing device 100. The upper and lower ends of the door handles 112 fit into door fixtures 116 attached to the storage unit 101 to prevent the right door 120a (122a) and the left door 120b (122b) from being left open.

[0031] The treatment device 100 is formed into a rectangular parallelepiped shape overall, and eaves 172 extend slightly forward from the ceiling of the first entrance 120 and the second entrance 122. The eaves 172 are provided to prevent corrosion of the door opening / closing hinges 114, door handle 112, and door fasteners 116, which are located on the front of the treatment device 100, due to rain falling on the treatment device 100, which is installed outdoors.

[0032] Similarly, to prevent the paint on the roof of the processing apparatus 100 from peeling off due to wind and rain, resulting in corrosion of the roof material, the roof slopes gently from the center of the processing apparatus 100 to both left and right ends, preventing raindrops from accumulating on the roof. An inlet 130 for introducing carbon dioxide gas (CO2) into the storage unit 101 is provided at the top of the side wall. The inlet 130 penetrates the side wall from the outside to the inside of the storage unit 101. In this example, the inlet 130 is provided on the side (side wall) of the storage unit 101, but the location is not limited thereto. For example, the inlet 130 may be provided on the right door 120a (122a), the left door 120b (122b), or the ceiling. However, providing the inlet 130 on the side or ceiling, i.e., a part other than the door, makes the storage unit more robust (since it is not a moving part) even when a tube or the like is connected to the inlet 130.

[0033] FIG. 3A is a plan view of processing device 100, and FIG. 3B is a front view of processing device 100 (viewed from the first entrance 120 side). Storage unit 101 is formed in a rectangular parallelepiped shape and includes: a base portion 110 at the bottom, which supports the load inside processing device 100 and has fork claw holes 104 formed therein; a floor plate 140 forming the upper surface of base portion 110; side plates 150 erected at both left and right ends of base portion 110; and a ceiling plate 170 provided at the upper end of side plate 150. The front side of FIG. 3B is first entrance 120 (open in FIG. 3B), and the rear side is second entrance 122 (closed in FIG. 3B). Both side plates 150 have metal siding on the surfaces exposed to the outside and particle board on the inner surfaces to form side walls.

[0034] The ceiling boards 170 that form the roof are made of plated or painted steel on the surface exposed to the outside and particle board on the inside. The floor boards 140 are made of waterproof plywood, and are structured to be resistant to corrosion even when forklifts or workers access the interior.

[0035] As described above, door fixing devices 116 are attached to the front end surfaces of ceiling panel 170 and base portion 110. Fork claw holes 104 are formed on the side surfaces of base portion 110. In this example, fork claw holes 104 are provided on the side surfaces, but depending on the relationship between width W and depth L, fork claw holes 104 may be provided on the front side (rear side).

[0036] Next, details of the inlet 130 provided on the side wall of the containing unit 101 are shown in Fig. 4. Fig. 4(a) is a front view of the inlet 130, Fig. 4(b) is a vertical cross-sectional view of the inlet 130, and Fig. 4(c) is a schematic diagram of the gas supply unit. The inlet 130 has a circular soft rubber plug member 132 that fits into an opening formed in the containing unit 101.

[0037] The plug member 132 forms a thin membrane on the outside of the side wall, and multiple slits 136 extending radially outward from the center are formed in the membrane. As a result, multiple fan-shaped fins 134 are formed in the membrane. A cylindrical fitting is provided on the back side of the membrane (inside the containing unit 101), which fits airtightly into the opening in the side wall. A stopper is formed on the back side of the fitting. If the fitting has virtually no gap in the radial direction, a stopper is not necessary.

[0038] The gas supply unit is a component for introducing carbon dioxide gas into the inside of the containing unit 101 through the inlet 130. The gas supply unit includes a gas supply source 900, a tube 902, and a valve 904.

[0039] A resin or metal tube 902 is fitted into the plug member 132 and is extended to the vicinity of the ceiling board 170 inside the processing device 100. Figure 5 is an image of an attachment jig 301 for fixing the tube, which is fixed to the ceiling of the storage unit 101. A carbon dioxide gas ejection part 300 fixed to the tip of the tube 902 is fixed by the attachment jig 301 to a framework material of the processing device 100 provided between the ceiling boards 170.

[0040] Mounting jig 301 is configured to include fixing tool 302 fixed to a framework material in the ceiling portion of processing apparatus 100, and inserting tool 303 fixed to jetting unit 300 and inserted into fixing tool 302 to fix the jetting unit and fixing tool 302. In this way, fixing can be achieved simply by inserting inserting tool 303 into fixing tool 302, so not only is fixing easy, but fixing tool 302 can be installed in various locations, and it is also easy to install multiple fixing tools, so jetting unit 300 can be easily fixed in various locations.

[0041] In this example, the ejection part 300 is fixed inside the accommodation unit 101 of the processing device 100 by the mounting jig 301 having the above-described configuration, but various other fixing methods can be adopted for fixing the ejection part 300. Furthermore, if the ejection part 300 is not fixed, the ejection part 300 and the tube 902 will move violently when the carbon dioxide gas is ejected, so it is desirable that the ejection part 300 be fixed.

[0042] Here, the fin portion (leak prevention packing) 134 of the plug member 132 through which the tube 902 is inserted is deformed in the insertion direction of the tube 902 by the insertion force at the time of insertion, thereby maintaining an airtight seal between the tube 902 and the plug member 132. In this Figure 4(c), the tube 902 is inserted from the inside to the outside of the processing device 100, but it goes without saying that the opposite may also be true.

[0043] In this case, the fin portion 134 is deformed toward the inside of the processing device 100, but the fin portion 134 is in tight contact with the tube 902 and the plug member 132, so airtightness is maintained between them.

[0044] The gas introduced into processing device 100 is carbon dioxide gas, which is led from gas supply source 900 to tube 902 via valve 904. Once a predetermined amount of cages has been carried into processing device 100, first entrance / exit 120 and second entrance / exit 122 are closed, and valve 904 is operated to supply carbon dioxide gas from gas supply source 900 to tube 902.

[0045] Once a predetermined amount of gas has been supplied, or until the gas concentration within the processing device 100 reaches a predetermined value, or once gas has been supplied (filled into the processing device 100) for a predetermined time, the valve 904 is again operated to stop the supply of carbon dioxide gas, and a predetermined time period is waited. After that, the cages are removed from the processing device 100, and sick animals and the like within the cages are collected and sent to the next process. Sick animals and the like can be transported into and out of the processing device 100 by hand (by quarantine personnel), but it is preferable to use a forklift or the like to minimize human (quarantine personnel) contamination.

[0046] The treatment device 100 is installed outdoors, where there are rarely any houses nearby, so a small amount of carbon dioxide gas leaking does not pose a problem. In addition, the better the airtightness, the better. In the present invention, further measures are taken to ensure the airtightness of the treatment device 100.

[0047] The treatment device 100 can be used as a storage shed and converted to treat avian influenza. While a conventional storage shed can be used as is, increasing the airtightness of the device can improve work efficiency. Generally, when used as a storage shed, if the interior is airtight, mold and other issues will develop if moisture or humidity accumulates inside. Therefore, the device is designed to ensure breathability while preventing theft and other issues.

[0048] Therefore, in the present invention, in order to achieve airtightness, the various airtight means shown in Fig. 6 are provided inside the processing apparatus 100. Fig. 6(a) and (b) show details of the sealing member 124, which is a rubber packing attached to the peripheral edge of the left door 120b, in a perspective view (Fig. 6(a)) and an AA cross-sectional view (Fig. 6(b)). Note that although the drawings show the left door 120b of the first entrance 120, the right door 120a of the first entrance 120 and the right door 122a and left door 122b of the second entrance 122 are similar.

[0049] The front surface (outside surface) of the left door 120b of the first entrance 120, which is exposed to wind and rain, is made of plated or painted steel plate 121a (hereinafter simply referred to as steel plate 121a or steel plate), which enhances its decorativeness and weather resistance. The inside of the door is made of plywood 121b to reduce weight.

[0050] Seal member 124, which is disposed around the four peripheries of left door 120b (the entire periphery of the door), is made of rubber or synthetic resin and includes door holder 124a overlapping the front surface of steel plate 121a, door holder 124d overlapping the front surface of plywood 121b, door thickness portion 124e extending in the thickness direction of left door 120b and formed to fit into left door 120b together with door holders 124a and 124d, seal reinforcement portion 124c extending upward from door holder 124d on the plywood side, and seal surface forming portion 124b extending upward from door holder 124a on the steel plate side and finally bent to form the exterior of seal member 124. Sealing surface forming portion 124b fits tightly against the front opening (door closing opening) of processing apparatus 100, thereby maintaining the airtightness of processing apparatus 100 and enabling the formation of an airtight space within processing apparatus 100.

[0051] Furthermore, as shown in Figure 6(c), the inner surfaces of the processing device 100, where the steel frame material and particle boards are joined, and where the particle boards are joined together, are caulked with a caulking material such as silicone rubber to form a caulking processing section 180, thereby sealing the processing device 100.

[0052] However, it is not completely sealed because if it were completely sealed, the internal pressure would increase when carbon dioxide gas was introduced, which would be dangerous. Therefore, it is desirable to have an airtightness that does not increase the internal pressure even when carbon dioxide gas is introduced.

[0053] Next, we will explain the means added to improve the portability of the processing device 100 according to the present invention. First, fork prong holes 104 are arranged on the side of the base 110 of the processing device 100. The fork prong holes 104 are provided on both sides.

[0054] Furthermore, eyebolt holes are usually provided in the roof, but in the present invention, to ensure airtightness of the roof and to prevent rainwater and the like from entering through the eyebolt holes, a substantially rectangular hanging ring 102 with openings 102b is welded 98 to the front and rear ends at the top of the side of the processing device 100 (FIG. 7 is a side view of the hanging ring 102). Since it is welded and fixed, corrosion of parts arranged near the hanging ring 102, such as hinges, caused by the eyebolt holes is reduced.

[0055] Next, we will explain how to use (culling method) the processing device 100. Figure 8 is a flow chart showing the procedure for using the processing device 100 (culling method).

[0056] First, in step S101, the doors (right door 120a, left door 120b) of the first entrance / exit 120 are opened, and sick animals, etc. are carried into the interior of the processing device 100 (inside the accommodation unit 101). The sick animals, etc. that are carried in may be housed in a rearing container. The accommodation unit 101 of the processing device 100 of the present invention is large enough to allow an epidemic prevention officer to enter inside, so when the sick animals, etc. are chickens, quails, ducks, etc., they can be easily housed in cages, which are common rearing containers.

[0057] In the past, diseased animals (e.g., chickens) were removed from their cages and placed in plastic bags or buckets, which were then filled with gas to suffocate them. In this case, quarantine personnel were divided into teams: one to remove the diseased animals from their cages, one to place the animals in plastic bags or buckets, and one to remove the suffocated animals from the bags or buckets and package them for transport to a processing facility (e.g., melting or incineration facility). Of these tasks, removing diseased animals from their cages was particularly difficult and could be the speed-limiting step of the entire process. One reason for this was that some diseased animals were considered suspected diseased but were not actually infected with a livestock infectious disease. Because these animals were in a "healthy" state, they often became violent when quarantine personnel unfamiliar with handling livestock attempted to remove them from their cages. This could delay the overall process. Furthermore, even though protective measures were in place, accidents could occur in which quarantine personnel were exposed to sick animals.

[0058] In the treatment device 100 of the present invention, sick animals can be transported directly into the housing unit 101 without being removed from the rearing container such as a cage, thereby preventing accidents such as those described above and significantly improving work efficiency.

[0059] Furthermore, one of the features of the culling of sick animals and the like using the treatment device 100 of the present invention is that it is more efficient because it takes into consideration the movement lines of disease prevention personnel and the like. This is because the housing unit 101 is provided with two opposite, airtightly closable entrances and exits, and the inside of the housing unit 101 can be made "one-way."

[0060] First, in this step (step S101), sick animals and the like are carried in from the first entrance / exit 120 side. In this example, it is the first entrance / exit 120 side, but this may also be the second entrance / exit 122 side. In either case, either one of the sides is used as the entrance for carrying in sick animals and the like.

[0061] Next, in step S102, the doors (right door 120a, left door 120b) of the first entrance / exit 120 are closed, and gas (carbon dioxide gas) is introduced into the processing device 100. At this time, the doors (right door 122a, left door 122b) of the second entrance / exit 122 are also closed. The carbon dioxide gas may be introduced from the gas supply unit described above in accordance with predetermined conditions. The conditions may be, for example, the gas supply time and the cumulative supply amount.

[0062] Gas supply from the gas supply unit may be performed manually by an operator (an epidemic prevention officer). In this case, the gas supply unit may be operated after confirming that the first entrance / exit 120 and the second entrance / exit 122 are closed. If the first entrance / exit 120 and the second entrance / exit 122 are equipped with sensors that detect a closed state, the gas supply unit may be configured to automatically supply gas according to predetermined conditions when the sensors detect a closed state. In other words, gas supply may be automatically started when a closed state is detected.

[0063] If the first entrance 120 and the second entrance 122 are equipped with sensors that detect the closed state, an alert can be generated if an attempt is made to start gas supply from the gas supply unit when the closed state of the door is not detected (the door is open). This can prevent unnecessary gas supply and accidents.

[0064] Next, in step S103, the doors of the second entrance 122 (right door 122a, left door 122b) are opened, and sick animals, etc. are carried out from the processing device 100. At this time, the carry-out exit is the entrance provided on the side opposite the carry-in entrance. In other words, when the first entrance 120 is used as the carry-in entrance, the second entrance 122 is used as the carry-out exit. In this way, sick animals, etc. within the processing device 100 will proceed in one direction.

[0065] As mentioned above, culling due to the outbreak of livestock infectious diseases occurs suddenly and requires a response within a limited time frame. Therefore, a large number of quarantine personnel must be mobilized and carried out all at once. These quarantine personnel are not necessarily specialized trained personnel (e.g., livestock quarantine officers), but the majority are general administrative personnel. To efficiently carry out the work, it is preferable to divide these personnel into teams: one to transport sick animals together with their feeding containers and place them in the processing equipment 100, and another to transport sick animals that have suffocated and died together with their feeding containers. In this case, providing two or more entrances to the processing equipment 100 allows personnel from each team to wait in front of each entrance and proceed with processing one after the other in a bucket brigade style, thereby making more efficient use of space and time. If there was only one entrance, the loading and unloading teams would become confused when opening the door after processing, and the cages being loaded and unloaded would interfere with each other, disrupting smooth flow.

[0066] Next, in step S104, the doors of the first entrance 120 (right door 120a, left door 120b) are opened again, and new sick animals or the like are carried into the processing device 100. In this example, steps S103 and S104 are performed sequentially, but these steps may also be performed simultaneously. Since the processing device 100 of the present invention has entrances on opposing side walls, even if both entrances are opened, there is no confusion because the people in charge of carrying out and carrying in are waiting in front of the entrances that they are responsible for. Furthermore, since sick animals or the like move in one direction within the accommodation unit 101, there is no interference between them.

[0067] As described above, according to this embodiment, the processing device 100 is portable, and the housing unit has multiple entrances and exits, so even quarantine personnel who have not received special training can efficiently cull sick animals, etc. Furthermore, by moving sick animals, etc. in one direction within the housing unit 101, the space around the processing device 100 can be used more efficiently. Therefore, for example, even when processing is performed by installing processing devices 100 next to each other with no gaps between them, there is no confusion or interference between quarantine personnel and cages, and culling can be carried out more efficiently.
