Description

MOBILE ABATTOIR APPARATUS,AND COMPONENTS, SYSTEMS, AND METHODS THEREFORFIELD

[0001] The present disclosure relates generally to a mobile abattoir apparatus and attendant components and systems. Further related are methods for manufacturing and utilising the mobile abattoir and its components.BACKGROUND

[0002] To obtain animal meat for consumption, animals are typically transported to abattoirs. Often, this requires travel over significant distances. This increases costs, causes inhumane treatment, and substantially diminishes the quality of the end product.

[0003] During transportation, animals are generally placed in confined areas without sustenance. Being in close confinement causes bruising of the animals and discoloration of the carcass that is prepared. Animals arrive at a slaughterhouse in a highly stressed condition and are subjected to further stress while there. All of these factors significantly reduce animal welfare, as well as the value and desirability of the meat that is produced.

[0004] In spite of such clear disadvantages, many countries require animals to be slaughtered and processed through a regulated abattoir. If animals are slaughtered outside of a regulated abattoir (e.g., on a farm or small holding), this is considered to be unregulated “home kill”, and the meat is barred from being sold. The result is that standard transportation and standard abattoirs continue to be used, and continue to cause significant negative impacts to animals as well as the resulting meat.

[0005] It is clear that there is a critical need for new apparatuses, systems, and methods which allow more humane, hygienic, efficient, and cost effective meat production.SUMMARY

[0193] As used herein, “approximately” means up to 10% greater or up to 10% lesser than a particular value, or up to 5% greater or up to 5% lesser than a particular value.

[0194] “Essentially” encompasses a dimension (e.g., length, width, height or depth, for example, length ‘A’) that is up to 10% greater or lesser than the dimension being compared, or up to 5% greater or up to 5% lesser than the dimension being compared (e.g., length, width, height or depth, for example, length ‘B’).

[0195] “Essentially vertical” encompasses an orientation that is up to 10° out from true vertical, or up to 5° out from true vertical. “Essentially horizontal” encompasses an orientation that is up to 10° out from true level, or up to 5° out from true horizontal.

[0196] The directional terms “top”, “bottom”, “upper”, and “lower”, as used herein are defined relative to apparatus, given the viewpoint of a person using the apparatus. For example, in relation to the chiller vehicle, this person can be positioned at the rear end of a chiller vehicle, facing inward. Alternatively, in relation to the processing envelope and its components, the person may be facing the processing envelope. The dimension of “length” for the apparatus is determined by measuring the apparatus from top to bottom, for example, with regard to aperson using the apparatus. The dimension of “width” for the apparatus is determined by measuring the apparatus from left to right, with regard to a person using the apparatus. The dimension of “depth” for the device is determined by measuring the apparatus from front to back, with regard to a person using the apparatus. The width and depth may be measured at the top or bottom of the apparatus or may be measured from a cross-section of the apparatus.

[0197] Unless the context requires otherwise, the terms “affixing”, “engaging”, “fastening”, “securing”, and the like, are not to be read as limited to direct connections, and may also include indirect connections. For example, a stated first component “engaged with” a stated second component may be engaged via, through, or by, one or more unstated interceding components.Apparatus and its components

[0198] The present disclosure encompasses a mobile abattoir apparatus along with associated components and systems that significantly improve processing efficiency and reduce processing times for animal carcasses. The disclosed apparatus, components, and systems thereby minimise the time between gate and plate.

[0199] The advantages for the consumer include the best tasting and freshest meat possible; reduced costs by reduced processing, marketing, and distribution margins; and accurate traceability of the animal and slaughtering process. The advantages for the animal producer include higher returns over schedule price; processing of animals on demand; and improved profitability, particularly for family farms and small holdings. The advantages for animal welfare include significant reduction in discomfort and stress; smaller stocking rates and increased rotation; and overall increase in feed leading to heathier stock. It is the aim of this disclosure to provide the noted benefits or to at least provide the public with a useful alternative.

[0200] In specific aspects, the disclosed mobile abattoir apparatus utilises a processing envelope, which can be used in conjunction with a chiller vehicle, and optionally, a service vehicle. The processing envelope provides, for example, a hygienic enclosure for slaughtering or butchering an animal. The chiller vehicle provides, for example, means for craning animals or carcasses and storing carcasses or carcass parts. The service vehicle provides, for example,storage for needed materials and / or waste materials. Each of these components is described in detail as follows.Retractable screens

[0201] The processing envelope includes one or more retractable screens and a roof extension. In various aspects, the one or more retractable screens are engageable with the roof extension, while the roof extension is engageable with the chiller vehicle. This arrangement is described in more detail, below. The one or more retractable screens are designed to create a hygienic slaughtering or butchering area and to inhibit entry of insects, birds, etc, into the processing envelope. The one or more retractable screens are designed to avoid the excess weight associated with rigid and fixed walls. This allows the processing envelope to be easily assembled and disassembled as needed.

[0202] As exemplifications, the one or more retractable screens may include one or more of: covers, curtains (e.g., drop curtains), panels, sheets, shutters, tarps (e.g., drop tarps), and movable walls (e.g., accordion walls; folding walls; retractable walls; sliding walls; etc), or others, or any combination thereof. The one or more screens may comprise any shape or combination of shapes. Noted in particular are quadrilateral shapes, for example, rectangular shapes. The one or more retractable screens may be slidable or rollable on a track or rail or rod, such as a curtain track, curtain rail, curtain rod, or similar. The one or more retractable screens may include one or more portions that are clear or semi-clear. The one or more screens may include one or more portions with perforations. The perforations can be used to allow airflow without allowing insect entry. The one or more retractable screens may comprise any material(s). Specifically noted are one or more of: water resistant materials, waterproof materials, and the like. Also noted are flexible metal meshes, flexible fibreglass meshes, flexible fabric meshes, and the like. Examples include one or more of: canvas (e.g., coated cotton), nylon, polyester, polyethylene, polypropylene, polyvinyl chloride, vinyl, and others. Any combination of materials may be utilised.

[0203] In certain aspects, the one or more retractable screens may be engageable with one or more fasteners. The one or more fasteners can be used to engage the screens together. The one or more fasteners can be used to engage the screens with the chiller vehicle. For example, the vertical edges or essentially vertical edges of the retractable screens may beengaged together. This can assist with exclusion of insects, dirt, debris, etc. As exemplifications, the one or more fasteners may include one or more of: bungees, buttons, catches, clamps, clasps, clips, elastics, hooks, hook and loop fasteners, latches, magnets, pegs, snaps, straps, ties, zippers, or others, or any combination thereof. Optionally, the one or more retractable screens may be engageable with a floor area, which is described below. As exemplifications, the floor engagement may include one or more of: bungees, catches, clamps, clasps, clips, elastics, hooks, hook and loop fasteners, latches, magnets, pegs, snaps, straps, ties, zippers, or others, or any combination thereof. Optionally, the one or more retractable screens may be engageable with one or more securements to keep the one or more screens in a raised position (e.g., rolled up or folded up). As exemplifications, the one or more securements may include one or more of: buttons, catches, chains, clamps, clasps, clips, hooks, hook and loop fasteners, latches, pegs, snaps, straps, ties, zippers, or others, or any combination thereof.Roof extension

[0204] Along with the one or more retractable screens, the processing envelope includes a roof extension. The one or more retractable screens are engageable with the roof extension as noted above. The engagement s) may be reversible. As exemplifications, the one or more retractable screens may be engaged with the roof extension by one or more of: buttons, brackets, catches, clamps, clasps, clips, hooks, hook and loop fasteners, latches, loops, pegs, snaps, straps, ties, wire, zippers, or others, or any combination thereof. In addition to or as alternatives to this, the one or more retractable screens may be engaged with the roof extension by one or more of: adhesives, bolts, nails, pins, screws, staples, stitches, studs, tacks, or others, or any combination thereof. The roof extension may include a rack for sliding or rolling the one or more retractable screens, such as a curtain track or similar. The roof extension may comprise any shape or configuration. Specifically noted are clamshell type roofs and pop-top type roofs.

[0205] Exemplary sizes for the roof extension include a width that may range at about 2 to about 2.5 m, or about 2.2 to about 2.5 m, or about 2.5 to about 3.5 m, or about 2.6 to about 3.6 m, or about 2.7 to about 3.7 m, or about 2.8 to about 3.8 m, or more, and a length that may range at about 2.5 to about 4.5 m, or about 2.6 to about 4.6 m, or about 2.7 to about 4.7 m, or about 2.8 to about 4.8 m, or about 2.9 to about 4.9 m, or about 3 m to about 5 m, or about 3.5 to about 5.5 m, or about 4 to about 6 m, or more. The roof extension may be comprised of oneor more materials including: fabrics, metals, plastics, resins, woods, and others, and any combination there of. The roof extension (and / or other part(s) of the processing envelope) may include one or more fans and / or one or more air filters as described herein. In certain aspects, positive air pressure may be provided inside the processing envelope. Positive air pressure can assist with the exclusion of unwanted matter from the processing envelop, e.g., insects, dirt, debris, etc. Other features may be included with the roof extension as desired.

[0206] As noted, the roof extension is engageable with the chiller vehicle. For example, the roof extension may engage with the chiller vehicle at or proximate to the roof top of the vehicle. The roof extension may engage with the chiller vehicle at or proximate to the rear of chiller vehicle. The engagement s) may be reversible. For example, the roof extension may be engaged with the vehicle by one or more of: brackets, clatches, clamps, clips, hooks, latches, mounts, screws, straps, ties (e.g., ratchet ties), or others, or any combination thereof. In particular aspects, the roof extension may be positioned on one or more roof rails. This allows the roof extension to be shifted in a rearward direction (e.g., slid or rolled) relative to the chiller vehicle. In certain aspects, the roof extension can be shifted rearwar d / outward so as to be cantilevered over the rear end of the chiller vehicle. In certain aspects, the rearward / outward shifting of the roof extension can be used to position the roof extension over the tailgate of the chiller vehicle, when the tailgate is lowered. The tailgate of the vehicle is described in more detail, below. When not in use, the roof extension can be shifted forward / inward, so as to be returned to a resting position. The resting position may be over the roof top (or at least a portion of the roof top) of the chiller vehicle.

[0207] In particular aspects, the roof extension may be comprised of a top portion, optionally a front portion, optionally a back portion, and one or more side portions (e.g., opposing sides). The top portion may be engaged with the one or more side portions. Where a front portion is included, this may be engaged with the top portion and may also be engaged with the one or more side portions. Where a back portion is included, this may be engaged with the top portion and may also be engaged with the one or more side portions. As exemplifications, the roof extension may be configured to comprise one or more flat sections. For example, the top portion of the roof extension may comprise a flat or generally flat configuration. Where present, the at least one side portion of the roof extension may comprise a flat or generally flat configuration. The optional back portion (and / or front portion) maycomprise a flat or generally flat configuration. Each of these may comprise any shape(s) and any materials(s). Noted in particular are quadrilateral shapes, including rectangular shapes. Noted also are metal, wood, resin materials, and any combination thereof.

[0208] In certain cases, the roof extension may a configured as a housing, for example, to provide a strong and stable covering. A top portion and side portion of the roof extension may be oriented perpendicularly or essentially perpendicularly relative to each other. A top portion and front portion of the roof extension may be oriented perpendicularly or essentially perpendicularly relative to each other. A top portion and back portion of the roof extension may be oriented perpendicularly or essentially perpendicularly relative to each other. A side portion and front portion of the roof extension may be oriented perpendicularly or essentially perpendicularly relative to each other. A side portion and back portion of the roof extension may be oriented perpendicularly or essentially perpendicularly relative to each other. A side portion and a back portion may extend lengthwise (downwards) to an extent that is greater than the lengthwise extension (downwards) of a front portion. Other configurations of these components are also possible.

[0209] It is possible for the roof extension to be oriented in a way to be horizontal or essentially horizontal, e.g., in relation to the roof top of the chiller vehicle. For example, the roof extension (e.g., the top portion of the roof extension) may be positioned so as to be parallel or essentially parallel to the roof top for the chiller vehicle. In further examples, the roof extension (e.g., the top portion of the roof extension) may be positioned so as to be parallel or essentially parallel to the roof top for the main trailer (e.g., cargo trailer). It is further possible for the roof extension to be sloped or to have one or more sloped sections, e.g., in relation to the roof top of the chiller vehicle. For example, the roof extension (e.g., the top portion of the roof extension) may be designed so as to have one or more sloping sections, e.g., sections that are angling or curving downward. This can assist with the shedding of leaves, rain, sleet, snow, etc.

[0210] In additional aspects, one or more retractable screens may be engaged with a top portion of the roof extension, e.g., positioned along the perimeter of the underside of the top portion. At least one retractable screen may be engaged with a front portion of the roof extension and / or at least one retractable screen may be engaged with a back portion of the roof extension. It is also possible for at least one retractable screen to be engaged with a side portionof the roof extension. For example, each of the side portions may have engagement with a retractable screen. As exemplifications, the one or more screens may be provided as preengaged with the roof extension or may be engaged with the roof extension when needed (e.g., during assembly of the processing envelope).

[0211] As particular aspects, two separate retractable screens (e.g., two hanging curtains) may be engaged on one or more tracks or rails or rods that follow along, or follow generally along, the outer perimeter of the roof extension. For example, a first retractable screen can positioned on a right section of the roof extension, and a second retractable screen can be positioned the left section of the roof extension. When rolled up or folded up, the first and second retractable screens can be stored against the roof extension. When unrolled or unfolded, the first and second retractable screens can be moved along the screen rails so as to meet together, e.g., at the front and back of the roof extension, to thereby form an enclosure. As various exemplifications, the one or more retractable screens may be retracted upwards by rolling and / or folding the screen(s), the one or more retractable screens may be extended downwards by unrolling and / or unfolding the screen(s); and / or the one or more retractable screens are extendable sidewards by sliding and / or rolling the screen(s) along a perimeter or part of a perimeter of the roof extension.

[0212] In noted aspects, the roof extension may be engaged with one or more roof rails, so as to provide a sliding or rolling movement for roof extension. The sliding / rolling engagement can be enabled by one or more intermediary devices, e.g., one or more of: wheels, tracks, rollers, runners (e.g., with ball bearings), or others, or any combination thereof. For example, a first roof rail can be engaged with a first section of the roof extension (e.g., right side). A second roof rail can be engaged with a second section of the roof extension (e.g., opposing side; left side). As a particular example, a first roof rail may be engaged with one or more intermediary means (e.g., legs) that engage with a first section of the roof extension (e.g., right underside of the roof extension). And along with this, a second roof rail may be engaged with one or more intermediary means (e.g., legs) that engage with a second section of the roof extension (e.g., opposing side; left side). As still a further example, a first roof rail may be engaged with a first section of the roof extension (e.g., on right underside of the roof extension) and this first roof rail may also be engaged with one or more intermediary means (e.g., legs). In turn, the intermediary means may be engaged with a first mount on the chiller vehicle (e.g.,at right side of the roof top of the chiller vehicle). And along with this, a second roof rail may be engaged with a second section of the roof extension (e.g., opposing side; on left underside of the roof extension) and this second roof rail may also be engaged with one or more intermediary means (e.g., legs). In turn, the intermediary means may be engaged with a second mount on the chiller vehicle (e.g., at left side of the roof top of the chiller vehicle).

[0213] The one or more roof rails may be oriented to be horizontal or essentially horizontal, e.g., in relation to the roof top of the chiller vehicle. For example, the one or more roof rails may be positioned so as to be parallel or essentially parallel to the roof top for the chiller vehicle. In further examples, the one or more roof rails may be positioned so as to be parallel or essentially parallel to the roof top for the main trailer (e.g., cargo trailer). As exemplifications, the one or more roof rails may be positioned onto the roof top of the chiller vehicle. For example, one roof rail may be positioned onto a right side of the roof top of the chiller vehicle, and one roof rail may be positioned on a left side of the roof top of the chiller vehicle. As further exemplifications, the one or more roof rails may be positioned onto the roof extension itself, and may engaged with the chiller via intermediary means (e.g., legs). For example, one roof rail may be positioned onto a right side of the roof top extension, and one roof rail may be positioned on a left side of the roof top extension.

[0214] In particular aspects, the one or more roof rails may be designed so as to extend beyond the rear portion of the chiller vehicle. In other aspects, the one or more roof rails may be designed not to extend beyond the rear portion of the chiller vehicle. In either case, the one or more roof rails can allow the roof extension to cantilever beyond the rear portion of the chiller vehicle. Optionally, one or more locks can be used to secure the roof extension in its position on the one or more roof rails. As exemplifications, locking may be achieved by one or more of: arms, couplings, links, pins, rods, tabs, or others, or any combination thereof. A particular example would be a connecting rod that is engageable with a section of the roof extension and is also engageable with the chiller vehicle or a panel on the chiller vehicle.

[0215] As noted above, it may be desirable for each roof rail to be engaged with a set of intermediary means, such as legs, which mediate an operative association between the roof extension and the chiller vehicle. The set of legs or other intermediary means may be engaged with the roof extension, and may be further engaged with the chiller vehicle. For example one or more legs may be engaged with a right section of the roof extension, and also a right sectionof the chiller vehicle. In the same way, or more legs may be engaged with a left section of a roof extension, and also a left section of the chiller vehicle. In certain aspects, the set of legs may mediate a sliding or rolling action for the roof extension, e.g., shifting rearwards and shifting forwards relative to the chiller vehicle. In further aspects, the set of legs may mediate lifting and lowering actions for the roof extension, e.g., raising upwards and lowering downwards relative to the chiller vehicle.

[0216] As specific exemplifications, each leg may include at least one linkage at or proximate to the roof extension. In particular, it is possible for each leg to include at least one linkage at or proximate to a roof rail (e.g., pivoting or hinging linkage). It is further possible for each leg to include at least one linkage at or proximate to the chiller vehicle (e.g., pivoting or hinging linkage). It is possible, as well, for the set of legs to be positioned parallel or essentially parallel to each other. For pivoting linkages, these may comprise at least one of: pin, bolt, boss, bush, disc, finger, gasket, nut, ring, rivet, washer, or others, or any combination thereof. As an example, a pivoting arrangement may include a bolt or similar, which accommodates one or more bushes. The pivoting arrangement may be held at each end by a plate or similar, for example, a cap, collar, cover, dome, flange, etc.

[0217] In particular aspects, the movement of the lower linkage and upper linkage of each leg may provide for a parallel motion, such that the leg(s) can facilitate movement of the roof extension upwardly and away from the roof rail, and the leg(s) can facilitate movement of the roof extension downwardly and towards the roof rail. This arrangement is illustrated herein. In noted aspects, the leg(s) may further assist in the movement of the roof extension rearwardly and forwardly in relation to the chiller vehicle. In particular, it is possible for each leg to be engaged with a guide that is adapted to transition along a roof rail. For example, a guide may be engaged with one or more of: wheels, rollers, runners (e.g., with ball bearings), or others, or any combination thereof. Accordingly, a guide can act as a rolling carriage along a roof rail. This arrangement is also illustrated herein.

[0218] In certain aspects, a set of legs or other intermediary means may be engaged with one or more supports. For example, supports may extend between two legs, such that a first leg (e.g., right leg) may be connected to a second leg (e.g., opposite; left leg) via one or more supports. This can reinforce and strengthen both legs. In further aspects, supports may extend between a set of parts engaged with the chiller vehicle. For example, supports mayextend between two legs engaged with the roof extension, such that a first leg (e.g., right side) may be connected to a second leg (e.g., opposite; left side) via one or more supports. As another example, supports may extend between two mounts engaged with a chiller vehicle, such that a first mount (e.g., right side) may be connected with a second mount (e.g., opposite; left side) via one or more supports. The supports may be provided in any arrangement relative to the legs, rails, mounts, etc., although a perpendicular or essentially perpendicular arrangement is specially noted. There may be one, two, three, four, or more supports between each set of legs, rails, mounts, etc. As exemplifications, the one or more supports may include: bars, brackets, chains, girders, rods, shafts, spars, yokes, or others, or any combination thereof. The supports may include any material(s). Noted are metal, wood, resin materials, and any combination thereof.

[0219] In further aspects, the first and second roof rails may be engaged with one or more braces. The one or braces can assist in holding the roof rails in position above the chiller vehicle. The one or more braces may be oriented to be vertical or essentially vertical. For example, the one or more braces may be oriented perpendicularly or essentially perpendicularly in relation to their associated roof rail. Other orientations are also possible. In specific arrangements, a first roof rail may be engaged with one or more braces, and such braces may be engaged with a first side of the chiller vehicle (e.g., right side). A second roof rail may be engaged with one or more braces, and such braces may be engaged with a second side of the chiller vehicle (e.g., opposing side; left side). The engagement of the brace(s) and the side(s) of the chiller vehicle may be direct or indirect. For example, it is possible for the first roof rail to be engaged with one or more braces, and such braces may be engaged with a panel that sits on or adjacent to a first side of the chiller vehicle (e.g., right side). Similarly, it is possible to the second roof rail to be engaged with one or more braces, and such braces may be engaged with a panel that sits on or adjacent to a second side of the chiller vehicle (e.g., opposing side; left side). When the one or more roof rails are engaged with their respective brace(s), this allows the roof extension to be shifted and cantilevered beyond the rear portion of the chiller vehicle.

[0220] In specific aspects, a roof top or a side wall of a chiller vehicle may be modified to allow slidable or rollable engagement with at least one section of the roof extension. For example, a chiller vehicle may adapted to contain at least one recess that extends proximal to the edge of the roof top and proximal to the rear end of the roof top. As exemplifications, theat least one recess may include one or more of: a channel, groove, gutter, slot, or another, or any combination thereof. In use, the at least one recess can be capable of receiving at least one section of the roof extension, and allowing sliding or rolling of the at least one section along the recess. The recess may be formed by a cutting or indentation made into the roof top, or a cutting or indentation made into the top of the side wall of the vehicle. As an alternative, a recess may be formed by an addition to the chiller vehicle. For example, a panel can be added onto a side of the chiller vehicle (see above), and a recess may be formed between the top of the panel and the roof top of the chiller vehicle. Alternatively, a track can be added onto the roof top of the chiller vehicle, the track including a recess to allow sliding or rolling of at least one section of the roof extension. It is also possible for a section of the roof extension to be engaged by sliding / rolling in the recess via one or more intermediate parts.Floor area

[0221] The processing envelope may be positioned so as to have a floor area. In certain aspects, the floor area for the processing envelope can comprise the tailgate of the chiller vehicle. For example, the tailgate of the chiller vehicle can be opened outward and lowered into a horizontal position or essentially horizontal position. In particular, the tailgate may be lowered to sit flat or essentially flat on the ground. Optionally, a tailgate extension may be added to the lowered tailgate to provide more floor space. The tailgate extension may be provided as a flap, a slat, a grate, or another, or any combination thereof. As exemplifications, the size of the floor area (e.g., a tailgate with or without a tailgate extension) may have a width and / or length ranging at about 2.2 to about 2.5 m, or about 2.5 to about 3.5 m, or about 2.6 to about 3.6 m, or about 2.7 to about 3.7 m, or about 2.8 to about 3.8 m, or more.

[0222] In specific aspects, the roof extension can be positioned above the tailgate in its horizontal position or essentially horizontal position. Where a tailgate extension is utilised, the roof extension can be positioned to extend rearwardly beyond the tailgate in its horizontal position or essentially horizontal position. As exemplifications, the roof extension can be positioned up to 1 m, or up to 1.1 m, or up to 1.2 m, or up to 1.3 m, or up to 1.4 m, or up to 1.5 m beyond the tailgate. Then, the tailgate extension can be added to the tailgate. In certain aspects, the tailgate is has automatic lifting and lowering functions. Tailgates with hydraulic lifting and lowering functions are particularly noted. For example, power tail lifts can be utilised.

[0223] As particular exemplifications, the roof extension may be utilised as follows. Once the roof extension is in place, the one or more retractable screens can be engaged with the roof extension and then extended sidewards around the roof extension and the tailgate / tailgate extension, and thereby set out the processing area. Alternatively, where retractable screens are pre-engaged with the roof extension, these can be extended downward (e.g., unrolled or unfolded) from the roof extension toward the tailgate / tailgate extension, and thereby set out the processing area. These methods allow quick and easy assembly of a processing envelope. Then, when the processing envelope is no longer required, the one or more retractable screens can be removed from the roof extension or returned to a retracted position (e.g., rolled up or folded up), the roof extension can be returned to its resting position, and the tailgate can be returned to its closed position on the chiller vehicle.

[0224] It is also to provide a floor area for the processing envelope that sits on top of the tailgate of the chiller vehicle. It is further possible to provide a floor area for the processing envelope that is independent to the tailgate of the chiller vehicle. For example, a floor extension for the processing envelope can be set on one or more rails on the cargo floor of a chiller vehicle such as a refrigerated truck. In certain aspects, a floor extension can be shifted in a rearward direction (e.g., slid or rolled) relative to the chiller vehicle using the one or more floor rails. In certain aspects, a rearwar d / outward shifting of the floor extension can be used together with the rearward / outward shifting of the roof extension, and thereby position the top and bottom for the processing envelope. Once these parts are positioned, the retractable screens that are engaged with the roof extension can be extended (e.g., unrolled) from the roof extension toward the floor extension. This again achieves quick and easy assembly of the processing envelope. When not in use, the floor extension can be shifted forward / inward to a resting position.

[0225] In further exemplifications, the, the roof extension may be utilised as follows. When the one or more retractable screens are in a retracted position (e.g., rolled up, folded up, or slid back), a carcass can be brought onto the floor area (e.g., onto the lowered tailgate). When ready to butcher, the one or more retractable screens can be transitioned to their extended position (e.g., unrolled from the roof extension). When the one or more retractable screens are in an extended position (e.g., extended sidewards and / or extended downwards, and optionally fastened together), this can form the enclosed area that is protected from insects and other pests. When the mobile abattoir is set for transit, the one or more retractable screens can be put intoa retracted position (e.g., rolled up or folded up towards the roof extension), or one or more screens can be removed, to provide less wind resistance to the vehicle and to protect the screens from damage.

[0226] With the roof extension in place, the floor area in place (e.g., tailgate or floor extension), and the retractable screens in a closed position, the processing envelope can comprise any shape or configuration. Specifically noted are cuboid, essentially cuboid, trapezoidal prism, and essentially trapezoidal prism shapes. Where the roof extension comprises a clamshell type roof, it will be understood that this may add headspace to the processing envelope that is triangular prism or essentially triangular prism in shape. As exemplifications, the height of the processing envelope may range at about 3.4 to about 4.4 m or about 3.5 to about 4.5 m, or about 3.6 to about 4.6 m, or about 3.7 to about 4.7 m, or higher. As further exemplifications, the length and / or width of the processing envelope may range at about 2.2 to about 2.5 m, or about 2.5 to about 3.5 m, or about 2.6 to about 3.6 m, or about 2.7 to about 3.7 m, or about 2.8 to about 3.8 m, or more.

[0227] Where the roof extension comprises a pop-top type roof, it will be understood that this may add headspace to the processing envelope that is trapezoidal prism, or essentially trapezoidal prism in shape. By lowering the floor area (e.g., using a hydraulic tailgate), this can provide a larger working area and larger headspace in the processing envelope. Optionally, a ramp may be utilised with the chiller vehicle and / or service vehicle. For example, a ramp may be used in addition to a tailgate to assist with loading / unloading, including loading / unloading to the processing envelope.

[0228] Within the processing envelope, it is possible to include a cradle to hold larger carcasses (e.g., beef or sheep). The cradle may be a portable cradle that can be engaged with the floor area once the floor area is put into position. The cradle may be permanently affixed to the floor area. For example, the cradle can be affixed to the inside of the tailgate of the chiller vehicle, such that the cradle is automatically put into position when the tailgate is lowered to be horizontal or essentially horizontal. Within the processing envelope, it is also possible to include a knocking box. The knocking box allows entry of a live animal and subsequent killing of the animal. The knocking box may be portable and may be engaged with the floor area once the floor area is put into position. The knocking box may be permanently affixed to the floor area. For example, the knocking box can be affixed to the inside of the tailgate of the chillervehicle, such that the knocking box is automatically put into position when the tailgate is lowered to be horizontal or essentially horizontal.

[0229] Included within the processing envelope may be a wash station. This may be a fully portable wash station, or the wash station may be engaged with the floor area once the floor area has been put into position. As another alternative, the wash station may be permanently affixed to the floor area. For example, the wash station can be affixed to the inside of the tailgate, such that the wash station is automatically put into position when the tailgate is lowered to be horizontal or essentially horizontal. Included within the processing envelope may be one or more fans and / or one or more filters. Exemplifications include one or more of: extraction fans, high volume fans, HVLS fans, high speed fans, or others, or any combination thereof. Further exemplifications include one or more of: activated carbon filters, electrostatic filters, fiberglass filters, foam filters, HEPA filters, pleated filters, refrigerator filters, UV filters, or another, or any combination thereof. For example, one or more fans and / or one or more filters may be positioned in the roof extension. Other features may be included for use with the processing envelope as desired.Chiller vehicle

[0230] The processing envelope may be utilised in conjunction with a chiller vehicle, and optionally, a service vehicle, as noted. In certain aspects, the chiller vehicle may be a refrigerated vehicle, such as a trailer (e.g., cargo trailer) or truck with refrigeration capacity. In other aspects, the chiller vehicle may be a vehicle with cool storage capacity, such as a trailer (e.g., cargo trailer) or a truck with cool storage capacity.

[0231] As exemplifications, a refrigerated truck, such as a refrigerated box truck, refrigerated semi-trailer truck, or similar, may be utilised. As other exemplifications, a cool storage truck, such as a cool storage box truck, cool storage semi-trailer truck, or similar, may be utilised. In particular aspects, the chiller vehicle may include both refrigeration and cool storage capacities. Exemplary sizes for the cargo holding portion of the chiller vehicle (e.g., cargo trailer) include widths ranging up to about 1.8 m, or up to about 2 m, up to about 2.5, or up to about 2.55 m, or wider as needed, and lengths ranging up to about 6 m, or up to about 8 m, or up to about 11.5 m, or up to about 12.6 m, or up to about 14 m, or up to about 18 m, or longer as needed. The payload capacity for the cargo holding portion of the chiller vehicle (e.g.,cargo trailer) may range from up to about 2 ton, up to about 3 ton, up to about 5 ton, or up to about 10 ton, or more as needed. In particular aspects, the chiller vehicle may have all wheel drive capabilities, four wheel drive capabilities, six wheel drive capabilities, or similar. The chiller vehicle may also be assisted by hydraulic power take off (hydraulic drive PTO), e.g., to allow operation of a main lifting device. The operation of a main lifting device (e.g., crane) is described further below.

[0232] The front and / or middle cargo areas of the chiller vehicle may include one or more areas designated for cooling. The cooling area(s) may include one or more components to speed the rate of cooling and / or increase the level of cooling for the carcass / carcass parts. Fan assisted cooling may be utilised. Refrigeration may be utilised, such as fan forced refrigeration. The cooling area(s) can include one or more vents, one or more air extraction means, and / or one or more air movement means. As exemplifications, this may include one or more of: air filters, fans, ducts, or similar, or any combination thereof. Various fans and air filters can be readily incorporated as described herein. The cooling area(s) can include one or more rails and / or one or more racks for storing the processed carcasses / carcass parts. It is expected that the meat rails and / or meat racks will provide storge for multiple carcasses or carcass parts (e.g., quartered carcasses). For example, accommodation can be provided for a total carcass / carcass parts amount of up to 6 large animals, up to 8 large animals, up to 10 large animals, or up to 12 large animals, or more (e.g., beef carcasses / carcass parts).

[0233] In certain aspects, at least one meat rail and / or at least one meat rack of the chiller vehicle are supported by one or more struts. For example, one or more struts may be positioned vertically or essentially vertically as supports for the meat rail(s). The struts may be any size as needed. As specific exemplifications, one or more struts may extend from the ceiling of the chiller vehicle to the floor of the chiller vehicle. Such struts may be securely engaged with the ceiling of the chiller vehicle to the floor of the chiller vehicle. This provides sufficient strengthening for the struts and make it possible to maintain the meat rail(s) in a horizontal or essentially horizontal position.

[0234] In other aspects, the meat rail(s) and / or meat rack(s) of the chiller vehicle may comprise one or more securements to assist in keeping the carcasses / carcass parts in place. As exemplifications, the securements may include one or more of: catches, chains, clamps, clasps, clips, dividers, hooks, latches, straps, strops, ties, or others, or any combination thereof. Whereracks are utilised, these may comprise one or more openings to assist cool airflow, for example, one or more of: cavities, holes, mesh, slits, slots, or others, or any combination thereof. In various aspects, the meat rails and / or meat racks may comprise one or more materials. Metal materials (e.g., steel, including stainless steel) are specifically noted.

[0235] The meat rails may be at any height. Where there are multiple meat rails being used, these may be different heights. Exemplary heights include ranges at about 1.6 to about 2.4 m, or about 1.7 to about 2.3 m or about 1.8 to about 2.2 m, or about 1.9 to about 2.1 m. The meat rails may be any length. Where there are multiple meat rails being used, these may be different lengths. In certain aspects, the meat rail may extend the length of the cooling area of the chiller vehicle, or approximately the length of the cooling area. In particular aspects, the meat rail may also extend outward beyond the rear portion of the chiller vehicle. For example, the meat rail may extend into the processing envelope, when the processing envelope is assembled. Various means may be utilised to allow for such outward extension. As one exemplification, the terminal portion of the meat rail, i.e., landing rail, may pivot so as to fold outward when the landing rail is needed, and to fold inward when the landing rail is no longer needed. As another exemplification, the landing rail may be telescopic so as to extend outward when the landing rail is needed, and to compress inward when the landing rail is no longer needed. In this way, the landing rail may assist in holding or transitioning the carcass / carcass parts from the processing envelope, when required, and still allow the closing of the rear of the chiller vehicle (e.g., closing of the tailgate).

[0236] In particular aspects, the chiller vehicle may include a main lifting device, such as a crane. The main lifting device may assist with loading carcasses onto the floor area. The main lifting device may also assist with moving carcasses into position on the floor area (e.g., onto a cradle). Advantageously, a main lifting device will have sufficient capacity to allow an animal / animal carcass to be lifted onto the floor area without dragging. This reduces the potential for contamination and allows weight to be transferred directly to the chassis of the chiller vehicle. As one exemplification, the main lifting device can be a truck mounted crane, which is also known as a lorry mounted crane or lorry loader. When provided for a trailer, this can be described as a trailer mounted crane. It is expected that the main lifting device will have hydraulic lifting and lowering functions. Specific examples include Fassi, HIAB, HMF,Liebherr, and Palfinger cranes. Noted in particular are compact cranes from Endura™ Equipped, such as Quicklift® cranes, including QL350.

[0237] The maximum lift capacity for the main lifting device (e.g., crane) may be, for example, at least 1000 kg, at least 1500 kg, at least 2000 kg, at least 2200 kg, at least 2400 kg, at least 2500 kg, at least 3000 kg, at least 3200 kg, at least 3500 kg, or more. The maximum lift capacity may range, for example, at about 1200 kg to about 2200 kg, or about 1400 kg to about 2400 kg, or about 1600 kg to about 2600 kg, or about 1800 kg to about 2800 kg. The maximum height for the crane at lift may be, for example, at least 1 m, at least 1.2 m, at least l.6 m, at least 2 m, at least 2.2 m, at least 2.6 m, at least 3 m, at least 3.2 m, at least 3.6 m, at least 4 m, at least 4.2 m, at least 4.6 m, or more. The maximum height at lift may range, for example, at about 1.6 m to about 3.6 m, about 2 m to about 4 m, or about 2.2 m to about 4.2 m, or about 2.6 m to about 4.6 m. The maximum reach of the main lifting device may be, for example, at least 2 m, at least 2.3 m, at least 2.5 m, at least 2.7 m, at least 3.3 m, at least 3.5 m, at least 3.7 m, at least 4 m, at least 4.3 m, at least 4.5 m, at least 4.7 m, at least 5 m, at least 5.3 m, at least 5.5 m, at least 5.7 m, at least 6 m, or more. The maximum reach may range, for example, at about 1 m to about 3 m, or about 1.5 m to about 3.5 m, or about 1.7 m to about 3.7 m, or about 2 m to about 4 m, or about 2 to about 5 m, or about 2 to about 6 m, or about 2.7 m to about 3.7 m, or about 2.7 m to about 4.7 m, or about 2.7 m to about 5.7 m. The weight at maximum reach may be for example, at least 500 kg, at least 600 kg, at least 700 kg, at least 800 kg, at least 900 kg, at least 1000 kg, or more. The stowed height may be, for example, about 1 m or less, about 1.2 m or less, about 1.4 m or less, about 1.5 m or less, about 1.6 m or less, or about 1.7 m or less.

[0238] In certain aspects, the main lifting device, such as a crane, may be situated in the cargo area of the chiller vehicle, e.g., a cargo area of a trailer or truck having refrigeration and / or cool storage capacity. For example, the main lifting device may be situated in the rear portion of the cargo area of the chiller vehicle. In particular, the main lifting device may be situated at a rear portion of the chiller vehicle which will be proximal to the processing envelope once assembled. In specific exemplifications, the main lifting device may be positioned within a range of about 0.5 to about 0.9 m, or about 0.6 to about 0.8 m, or about 0.7 to about 0.77 m from the rear end of the chiller vehicle. Optionally, the main lifting device may be separated from the one or more cooling areas by a wall. The wall may include a door, suchas a sliding door. This walled off arrangement can maximise cooling while also maintaining hygiene in the cooling area.

[0239] It is also possible to include supplementary lifting devices with the chiller vehicle. As exemplifications, such devices may include one or more of: booms, hoists, pulleys, winches, or others, or any combination thereof. In certain aspects, the supplementary lifting device(s) may have moderate lifting capacity, for example, about 50 kg to about 300 kg, or about 80 kg to about 200 kg, or about 120 kg to about 160 kg. As further exemplifications, one or more winch pulleys and one or more remote winches may be utilised. In particular aspects, one or more winch pulleys may be utilised. In further aspects, one or more hoists may be utilised. For example, supplementary lifting devices may be used proximal or adjacent to the roof extension and / or the processing area. In particular aspects, supplementary lifting devices may be engaged with the roof extension. In other aspects, supplementary lifting devices may be remote from the roof extension and / or the processing area. For example, such may be used in the cargo trailer, e.g., in one or more cooling areas. Other features may be included for use with the chiller vehicle as desired.

[0240] As particular examples, one or more supplementary lifting devices may be employed where a landing hook can facilitate the quartering of a carcass. In certain aspects, one or more landing winches and / or one or more landing hoists may be utilised. Specifically, at least one landing winch and / or at least one landing hoist can be used to assist with de-hiding and processing of very large carcasses. In certain aspects, at least one landing winch and / or at least one landing hoist may be included proximal to the roof extension. For example, the at least one landing winch and / or at least one landing hoist may be engaged with the roof extension (e.g., suspended therefrom). In specific aspects, at least one landing winch or at least one landing hoist may be hung from a spreader bar. For example, a landing winch or landing hoist can assist in removing the forequarters before the hindquarters are landed. Use of the landing winch or landing hoist as a supplementary lifting device together with the crane as a main lifting device can enable processing of oversized carcasses within the processing envelope. This is described in more detail herein.

[0241] Optionally, the chiller vehicle can include one or more areas for storing implements for slaughtering and butchering. This can include secure areas for ammunition, captive bolts, electric stun devices, firearms, knives, and / or sharpeners. As other options, thechiller vehicle can include one or more of: sterilisers, water heaters, water pressure pumps, water stations, water hoses, hose reels, or others, or any combination thereof. The chiller vehicle can also include one or more inspection areas. As other options, one or more service vehicles may be used in conjunction with the chiller vehicle. The service vehicle may comprise a trailer, for example, an enclosed trailer. Exemplary sizes for the service vehicle (e.g., enclosed trailer) include widths of up to about 1.2 m, or up to about 1.5 m, or up to about 1.8 m, or wider as needed, and lengths of up to about 1.8 m, or up to about 2.4 m, or up to about 3 m, or longer as needed.

[0242] In certain aspects, the service vehicle may be towable by the chiller vehicle or another vehicle. The service vehicle can be utilised for providing auxiliary storage and / or facilities. For example, the service vehicle may carry one or more of: califonts, compressors, generators, gas supply (e.g., LPG canisters), hoses, hose reels, water pumps, water storage, and waste storage (e.g., for offal or other offcuts), or others, or any combination thereof. As exemplifications, the waste storage may include one or more of: bags, bins (e.g., wheeled bins), boxes, sacks, or others, or any combination thereof. To minimise waste, it is possible for rendering and / or onsite alkali hydrolysis to be utilised. Other supplementary storage means or facilities may be included with the service vehicle as desired.Systems

[0243] The disclosed components and systems allow the user to quickly and easily: load an animal / carcass and assemble the processing envelope for processing, then when finished, disassemble the processing envelope and allow travel of the mobile abattoir.

[0244] In certain aspects, the processing envelope may be provided as its component parts or as an assembled unit. For example, the roof extension may be provided, or the one or more retractable screens may be provided, or the roof extension may be provided along with the one or more retractable screens. In specific aspects, the roof extension may be provided as being pre-engaged with the one or more retractable screens. Alternatively, the roof extension and the one or more retractable screens may be provided along with means to allow engagement between the roof extension and the one or more screens. In particular aspects, one or more screens can be provided with the one or more fasteners to fasten the one or more screens together (e.g., along vertical edges) and / or the one or more securements to secure the one ormore screens in a retracted position (e.g., rolled up or folded up at or proximate to the roof extension).

[0245] In further aspects, the processing envelope may be provided as pre-engaged with the chiller vehicle. Alternatively, the processing envelope may be provided separately from the chiller vehicle. As an example, the processing envelope may be provided with means to allow engagement between the processing envelope and the chiller vehicle. The means provided may allow engagement between the roof extension of the processing envelope and the roof top of the chiller vehicle. For example, the roof extension may be positioned on one or more rails on the roof top of the chiller vehicle, as described herein. In additional aspects, the chiller vehicle may be provided withMethods of use and manufacture

[0246] Previous transportable abattoirs have been unwieldly and expensive, and unsuitable for small farm or small holding usage. The mobile abattoir as described herein is exceedingly manoeuvrable and cost effective. It significantly reduces the time needed to set up and clean up between animals. This in turn allows more animals to be processed. Because the mobile abattoir is utilised in situ, this avoids the significant physical and perceptual stressors for animals that are associated with traditional transportation and slaughterhouses. This provides substantial improvements in animal welfare as well as meat quality.

[0247] The mobile abattoir of this disclosure may be utilised and adapted as needed. In one particular aspect, the process includes one or more of: (1) optionally, moving the chiller vehicle into position; (2) lowering the tailgate of the chiller vehicle to create a floor area; (3) positioning a carcass in or on the floor area (e.g., using crane provided in chiller vehicle); (4) assembling the processing envelope; (5) processing the carcass in the processing envelope; and (6) storing the processed carcass in the chiller vehicle.

[0248] In one other aspect, the process includes one or more of: (1) optionally, moving the chiller vehicle into position; (2) lowering the tailgate of the chiller vehicle to create a floor area; (3) assembling the processing envelope; (4) killing and positioning the animal in or on the floor area (e.g., using crane provided in chiller vehicle); (5) processing the carcass in the processing envelope; and (6) storing the processed carcass in the chiller vehicle.

[0249] As exemplifications, the assembly of the processing envelope can include one or more of (1) sliding or rolling the roof extension to allow positioning over the tailgate of the chiller vehicle and extending the one or more retractable screens (e.g., downwards and / or sidewards); (2) optionally, engaging the one or more retractable screens along their vertical or essentially vertical edges; and (3) optionally, engaging the one or more retractable screens with the lowered tailgate along their bottom edges.

[0250] As exemplifications, the procedure carried out in the processing envelope can include one or more of (1) removing head, hocks, skin, guts and quartering the carcass; (2) removing cheeks and tongue, clearing edible offal to bags, placing pet food parts in bins, and transitioning all retained material to the cooling area(s) (e.g., via landing rail(s) / meat rail(s)); (3) placing inedible offal into bins for loading onto the service vehicle; (4) washing down the processing envelope area; and (5) optionally, repeating these steps with the next carcass.

[0251] For very large animals, the loading procedure can include one or more of (1) lifting carcass onto the carcass cradle positioned on the floor area (e.g., on lowered tailgate); (2) removing head and hocks and skinning hide down to cradle; (3) with the main lifting device (e.g., crane), lifting the carcass up with a spreader bar and eviscerating carcass; (4) splitting the carcass down the spine and partially cutting the forequarters so as to make the carcass foldable (e.g., the forequarters can remain attached to the hindquarters by a belly flap); (5) engaging the forequarter region with the supplementary lifting device (e.g., landing hoist) proximate to the roof extension, and lifting with a second spreader bar; (6) completing the cutting for the forequarters (e.g., cut into two portions) and landing the forequarters onto the landing rail; (7) transitioning the cut forequarters towards the cooling area; (8) with the main lifting device, landing the hindquarters onto the landing rail; and (9) transitioning the hindquarters towards the cooling area. This procedure can allow processing, storage, and transport for oversized carcasses (e.g., carcasses longer than 1.5 m).

[0252] The components and processes of the mobile abattoir enable a licenced abattoir operator to work efficiently and effectively in the field. For example, for convenience, a chiller vehicle can provide access to all needed tools such as air blades, knives, steel, splitting saws, amongst others. As other examples, a tool steriliser and a hand wash station can be provided. After one or more processing jobs, the stored carcasses / carcass parts can be delivered forsecondary processing, e.g., at a local butcher. After this delivery, the chiller vehicle and processing envelope can be foamed and washed down ready for the next jobs.

[0253] It will be understood that the disclosed mobile abattoir can be adapted for use with many different animals. Examples include but are not limited to: alpaca, bison, boar, buffalo, camel, caribou, cattle, deer (including chital, fallow deer, mule deer, musk deer, red deer, reindeer, roe deer, rusa, sambar deer, sika deer, white tailed deer, and others), elk (including wapiti and others), emu, goat, kangaroo, llama, oryx, ostrich, pigs, sheep (including lambs), yak, and zebu. The weight of the animal / carcass may range, for example, about 70 kg to about 700 kg, or about 80 kg to about 800 kg, or about 90 kg to about 900 kg, or more.

[0254] Various manufacturing methods may be utilised for the disclosed mobile abattoir and its components. As exemplifications, the one or more retractable screens may be produced by: crimping, extrusion, lacing, stitching, webbing, weaving, or other methods, or any combination thereof. As further exemplifications, the roof extension may be produced by: extrusion, moulding, rolling, welding, or other methods, or any combination thereof. Where the roof extension is provided to be pre-engaged with the one or more retractable screens, this can be achieved by: gluing, nailing, screws, sewing, stapling, tacking, or other methods, or any combination thereof. Where the floor area (e.g., tailgate) for the processing envelope is to provide affixed features such as a cradle or a knocking box, this can be achieved by: cutting, bolting, drilling, welding, or other methods, or any combination thereof. Similar methods may be utilised for obtaining other features for the chiller vehicle, including the meat rails, meat racks, ventilation, etc.Specific exemplifications
