1. Field
The field relates generally to poultry processing and more particularly to handling, growing and transporting live poultry.
2. Background Art
Loading and unloading birds and transportation of live birds from the hatchery stage through the kill stage at a production facility is a challenging task. The birds have to be gathered, contained and transferred to a transport means and subsequently unloaded with minimal damage or harm to the animal, which is challenging because birds instinctively resist such movement. For example, transport of live poultry from the hatchery to growing houses and from growing houses to processing facilities is required. One method of transport of live poultry is containing the birds in cages and stacking the cages on a truck with a flatbed trailer for transport. Loading and unloading trailers with live animals, particularly from a location where the animals are grown or raised to a processing facility, can in the case of chickens, increase the stress level of the animal. With heightened stress, animals are more likely to have increased body temperature, experience bruising, dislocated wing/leg joints and potential tissue damage along with an increased pH level, which may affect the quality of the muscle. Once the birds are captured in cages, the cages must be loaded on the trailer.
Existing systems involve crews of catchers to unload the birds from the growing colonies and load them for transport means. Loading of the cages on the trailer consumes the full time of one operator to move cages from the house or growing area to the trailer and it requires skill to stack cages on the trailer so that they can be properly secured for transport. The cages often become damaged in this operation over time and need to be repaired and eventually replaced. Damage to the cages often involves the doors through which the birds are inserted. Poorly operating doors leads to increased time to load cages and potential bird damage.
There are significant labor issues because it is very labor intensive and requires some level of skill and training. There are health issues for both the birds and the handlers. The labor intensive handling of the birds promotes infections of the handler and risks harm to the birds. This results in numerous health and safety concerns. The cages are prone for damage which can cause bird damage and extensive time and labor is utilized to fill the cages with birds and load and secure them for transport. The cages or other transport containers also have to be cleaned prior reuse, which can also be a labor intensive and costly effort.
Loading of poultry is a cumbersome and time consuming task. In the catching process, the poultry are placed into cages. Some cage designs consist of “drawers” and can vary from 10 to 15 drawers averaging a 20-25 bird capacity per drawer. Birds can be placed into the cages either manually or by semi-automatic means. A forklift then can load a flatbed truck with 18-22 cages that are stacked in pairs. Once the cages are in place, each stack has to be secured by chains to the frame of the trailer.
Semi-automated methods of harvesting the birds in the houses have encountered mechanical and functional problems. In one sense this semi-automated method eliminates the need for operators to physically pick up the birds. However, operators are still needed to operate the equipment and to move the birds forward and away from the sides of the house. Therefore, some handling is still necessary.
Plastic poultry trays or drawers are sometimes used to transport and house birds temporarily, however, these systems are temporal and only used during certain stages and are not integral with growing systems or transport systems. Use of such trays or drawers still require significant handling of birds, though they may be somewhat more durable than metal cages. Further, these plastic poultry trays, though less often than the standard cages, are also subject to damage or breakage resulting in a need to replace the entire tray, even though only one area of the tray may be cracked or otherwise damaged. The plastic trays are likely easier to clean and sanitize than the standard cage but given the size of the typical plastic tray and the webbing of the mesh, they also can be difficult to clean. Also, storing trays when they are not in use can consume a large amount of space.
As noted above, problems occur with, loading, unloading, harvesting, placing birds into cages (plastic drawers or trays), loading the cages on a transport, and transporting to the processing facilities. Also, current processes are labor intensive and costly. The problems occur as the DOC (Day Old Chicks) are transitioned from the hatcheries to the growing centers and then to the production facilities. A new system and method for harvesting, loading, growing, transporting, and unloading is needed that addresses the above problems by reducing physical handling of the birds from the hatchery stage through the kill and production stage. In the new system and method, the device by which the birds should be transported should be reusable, interchangeable, and easily cleaned.
The technology involves a system and method for handling poultry comprising a colony basket apparatus utilized throughout the process of transitioning the DOC from the hatchery, to the growing facility, through the growing process, and on to the production facility. The colony basket apparatus is utilized for harvesting, loading and unloading, growing, transport, storing and holding through the shackling process prior to the kill process. The method utilizes the colony basket apparatus to perform the steps of retrieving and loading a grouping of the DOC into the colony basket at the hatchery, transporting the same grouping of birds in the same colony basket to the growing facility, loading the colony basket containing the original grouping of birds into the colony system of the growing facility, growing the DOC to Broilers (chickens bred and raised specifically for meat production) in the original colony basket in which they were installed, removing and harvesting live poultry from the colony system while maintaining the same grouping of birds in the same colony basket in which they were originally placed, stacking and loading the colony basket of Broilers on a transport, transporting to a poultry production facility, unloading the colony basket and temporarily storing the poultry in the same colony basket for subsequent killing. The invention more particularly relates to a new portable colony basket for holding and making possible all necessary functions for the poultry animals from the DOC stage, through growing, through transport and up to production while maintaining a grouping of birds or subset thereof in the same colony basket throughout the process all of the way through the shackling process.
The concept of harvesting poultry utilizing one type of colony basket uniformly throughout the entire process from capturing the DOC at the hatchery to growing houses equipped with colony systems and on to production will make the process more efficient and will result in less worker and animal stress by resolving many of the problems related to the current methods of manually catching birds and placing in cages or other containers or using semi-automated systems to harvest and transition poultry. With the present invention, stackable tray colony baskets can be utilized that can be placed into and retrieved from colony systems in growing houses using automated systems and can be transferred and retrieved from transports when transitioning between locations within the overall process and the colony baskets can be further integrated with feeding and watering systems. The trays can be made from molded plastic or other material including metal aluminum metal and can have an open grid flexible flooring elevated above a lower manure trap flooring to keep the birds out of their manure and the sides can be vented. The bottoms can have an open grid pattern bottom to allow the birds to grasp with their paws to stabilize and reduce wing flapping, but the floor can also be flexible to reduce injury to the bird. The grid pattern also allows debris and feces to fall out to reduce cleaning and increased airflow to ventilate the birds. The top and bottom perimeter edges of the cages can be complimentary in shape for ease of stacking and stability reducing lateral movement of the stacked trays with respect to each other. The sides of the trays can also have vented openings. Once an upper tray is stacked on top of a lower tray, birds placed in the lower tray are contained. The upper most tray in a stack of trays can be capped by an additional empty tray or other cover or ceiling in the colony system or in the transport or other automated transitioning means.
An empty stack of colony baskets can be transported to a hatchery and loaded with DOC. The stack of colony baskets containing DOC can be loaded on a transport rack, which receives the colony baskets and transported to a growing house from the hatchery. The colony baskets can be unloaded from the transport rack to be transferred into a poultry house colony system manually or the transfer can by automated by a powered mover or conveyor and/or loading system. This method provides that no container stacks have to be manually or mechanically un-stacked for loading poultry because the DOC are already in the colony baskets. Previous systems required that trays be removed from a stack and then the poultry would be loaded into the trays and the trays are re-stacked, a powered mover can transport the trays to the outside to be loaded onto the trailer. The process of loading and unloading birds in the growing house has been eliminated.
The construction of the trailer can be a flatbed trailer with vertical framework to make up the structural integrity as well as to hold the stacks of individual colony baskets. There can be a plurality of vertical and horizontal rails to insure the structure and flexibility of the size and number of colony baskets the transport is capable of handling.
With the design of the present invention, there can be a frame work constructed on the transport trailer holding a lightweight material that can be pulled alongside the trailer to cover the sides. This shroud can create an envelope in which the environment can be better controlled and provide a more suitable environment for the animals
Once the trailer arrives at the plant, the colony baskets can be unloaded and automatically moved into a warehouse or holding facility. This process can be performed as trucks arrive in order to build an entire storage of birds for a production shift. The trucks can be automatically unloaded in a very short period of time, thus eliminating the need for a forklift. The system can work in a “last-in first-out” method. The process can be improved through the efficiency of bringing the birds in the same colony basket that originated at the hatchery and the same colony basket continuing through the growing process and on to the production plant kill area and not consuming time loading and unloading birds into and out of cages or other containers.
The automated unloading can be done automatically to pull the trays off the trailer (or flatbed of transport) from the side of the truck in the stacked formation into a transport rack or onto either a conveyor or pull chain system. The transport rack or the conveyor can take the trays to the staging area where they can be un-stacked manually or by using destacker equipment.
With the proposed method, the colony baskets provide a perfect transport, growing container and housing means all in one unit to move the birds through the entire process. This system can eliminate the unnecessary handling of the birds and possibly make the process more efficient.
In another implementation of the present technology, a modular colony basket (modular tray) is used for the colony basket apparatus. The modular basket can comprise a floor formed of mesh panels and modular side walls that receive a beam extending through a hinge element connecting mesh panels to the floor. As in the previously described colony basket, the modular basket is stackable with other modular baskets and can have all of the functionality and interfaces as the non-modular implementation. The modularity of the basket allows the basket or tray to be periodically disassembled for routine scheduled cleaning and sanitizing, which would be easier than trying to clean and sanitize the whole basket. Further, if only a small section of a basket/tray is damaged, the modularity provided with this implementation allows a given section to be replaced without disposing of the entire tray.
There are a number of advantages to the design of the present invention for harvesting poultry. Safety is increased for the handler and the birds and health risks are reduced. The efficiencies of handling and transporting birds is improved and the process is less labor intensive and causes less stress on animals.
Moreover, because the present invention teaches the use of a modular colony basket, a method is provided wherein the devices used to transport the birds may be easily disassembled and cleaned before being reassembled.
These and other advantageous features of the present invention will be in part apparent and in part pointed out herein below.

The process can begin at the hatchery where a grouping of birds (for example DOC) are gathered and placed into a colony basket. A plurality of baskets can be stacked on over top of another for transport. A netting material can be shrouded over each colony basket to assist in containing the birds. The grouping of birds and their respective colony basket in which they are placed can remain in the same colony basket throughout the process until they are removed as broilers at the kill station. This reduces the handling of the birds to avoid injury and helps to prevent the spread of bacteria or disease between bird groupings. The grouping of DOC can be transported to a growing house in the same colony basket in which they were originally placed at the hatchery, where the poultry are grown for future processing. At the growing location there can be a series of growing colony racks for housing the colony baskets with the original grouping of birds placed therein at the hatchery. At the growing facility, the colony baskets can be integrated with water and feed channels and watering and feed troughs. The colony baskets can have a specific configuration to integrate with the watering and feeding systems as outlined herein in order to assist poultry going through the growth process and assist the operators at the growing facility for attending to the birds. When the poultry have completed the growth process, now in the broiler stage, they can be transported to a location for processing as a final food product. A transport can arrive at the growing location to receive the poultry that have completed the growth process. The transport system can be a truck and trailer combination. The trailer can be a standard flatbed trailer on which colony baskets containing the fully grown poultry can be loaded. The colony baskets containing the original grouping of birds, or some subset thereof, can be transferred from the colony racks of the colony system to the flatbed of the transport. A netting material can be shrouded over each basket before it is stacked in order to assist in retaining the bird. The colony baskets can be stacked one atop another. The transport can be loaded with the fully grown birds and transported along a travel route to an unloading station at a processing facility. The transfer system for transferring the colony baskets from the colony racks to the flatbed can be automated as described herein.
The unloading station can include an automated unloading system for automatically unloading a colony basket stack from the trailer for storage in an adjacent storage area of the processing facility. Tray stacks can be conveyed to a storage location having a climate controlled storage facility for housing the poultry in the stacked configuration prior to the rendering process. The storage area can be operated on a first in first out system such that a given colony basket stack does not dwell in the storage area for an extended period of time. The storage area can also have a system for controlling and tracking the weight of the tray stacks which could ultimately provide weight information regarding the fully grown poultry.
Within the storage facility there can be an automated unstacking system for unstacking the colony basket stacks for conveyance through the processing facility. There can be a stunning system utilized including a gaseous environment for stunning the poultry or it can include an electric shock stunning system or a combination of the two. If a gaseous environment stunning system is utilized, the gaseous environment can be a multi-stage stunning system where the first stage(s) can be a combined induction phase and the second stage(s) can be the combined stunning phase. This system can generally be referred to as a controlled atmosphere stunning system or CAS. Once the colony baskets containing the original grouping of birds/poultry have transitioned through the stunning system, the poultry can be unloaded from the trays at an unloading station. The unloading station can comprise an automated unloading system which is operable to tilt the colony baskets sufficiently to remove the stunned poultry from the colony baskets. This is the first point in the process that the birds are removed since their original placement into the colony basket at the hatchery as DOC. Once removed from the colony baskets, the stunned poultry can be conveyed to a shackling station where the poultry can be hung from a shackle conveyor for being conveyed to a plant evisceration facility.
As described the colony baskets can be stackable. Further the colony basket can have an interwoven wire mesh elevated floor above the colony basket bottom floor where the mesh openings are sufficiently large for debris to pass therethrough and also providing a means for the bird to grasp hold in order to stabilize itself and the mesh floor can be flexible in order to avoid injury to the birds. The frame of the colony baskets include various portions including perimeter top and bottom rim flanges and upright vented side walls. The upward facing surface portion of the upper perimeter top rim flange can be designed to be complimentary with respect to the downward facing portion of the bottom perimeter rim flange. This complimentary configuration can be designed such that the trays interlock when they are stacked thereby resisting longitudinal and latitudinal movement of the trays with respect to each other.
The stackable tray can be constructed having a top rim flange and a bottom rim flange, which defines the longitudinal and latitudinal dimensions of the tray. The top and bottom rim flanges can have L-shaped cross sections. The inner perimeter of the top rim flange can define an upper opening or upward facing opening through which birds can be easily inserted. The bottom rim flange defines the perimeter of the lower or downward facing opening closed off by the solid floor. The solid floor can have elevators for elevating the mesh floor proximately above the solid floor. The mesh flooring is designed with vented openings where the openings are sufficiently large to allow debris to pass there through. The flexible mesh floor design provides for a surface that can be grasped by the talons of a bird without injury. Upright side walls can be attached around the perimeter of the tray and attached to support members. The inner perimeters of the top rim flange and the bottom rim flange, which define the upper and lower openings respectively, can have substantially the same geometry.
The top rim flange can include stabilization standoffs which can extend vertically. The top rim flange can have on an upper surface a vertical standoff The flange and the complementing recessed receptacle on the underside of the colony basket when engaged, one with respect to the other in a stackable fashion, they can resist longitudinal and latitudinal shifting of trays, one with respect to the other. Also, the stabilization standoffs can be placed along the latitudinal and longitudinal sides of the top rim flange. The spacing between the longitudinal, the latitudinal, and the corner upright support ribs define the vented openings of the tray. The spacing between the support members and the height of the support members can be optimized depending on the type of bird being contained within the stackable trays.
For stacked colony baskets the uppermost colony basket can have a top cover or a netting installed of the uppermost colony basket. The top cover can have a mesh screen for covering the opening of the uppermost tray. The perimeter of the mesh screen can be defined by the top cover flange. The top cover flange can have recessed receptacles for interfacing with the raised standoffs of the uppermost tray.
The colony basket stacks can be transitioned to the transport and loaded on the flatbed by way of a transfer rack or loading dock or other means for loading the colony basket stacks. Vertically protruding standoffs can be provided on the flatbed for and dimensioned to be received by the recessed receptacles of the lower most colony basket in a stack. The transport can have a shroud covering for better controlling the environmental exposure of the poultry. The shroud covering can be supported by transport side rails. One or both of the side panels of the shroud covering can be a retractable curtain for exposing the flatbed from either side. The shroud covering can also have a rear transport cover opening and or a side transport cover opening through which colony baskets can be loaded.
The stacked colony baskets can be loaded through the transport cover opening by sliding them along tray tracks which extend along the flatbed. The trailer can be a standard trailer; however, the trailer can have side railings for supporting shroud covering. The top surface of the flatbed can have raised standoffs that conform to the recessed receptacles on the underside of the tray to restrict lateral sliding or movement of the bottom most tray.
The technology described above includes an additional embodiment. In the additional embodiment, the colony baskets described herein above are replaced with modular baskets. The modular baskets may be utilized and integrated interchangeably with the invention described above.
Each basket 2710 comprises a floor formed by an array of interconnected molded plastic floor panels 2720. The floor comprises a plurality of corner panels, edge panels and middle panels. Each floor panel can be formed as a flexible mesh panel for allowing animal waste and other debris to drop through while providing a comfortable surface for poultry. In the illustrative embodiment, each floor panels 2720 are identical and formed from the same mold, though the invention is not so limited.
Interconnected side panels 2750 are connected to the floor panels 2720 to form side walls for the basket 2710. As described below, the side panels receive beams that connect the floor panels to each other to connect the side panels to the floor. The side panels have pliable mesh of expanding size. As also described below, the basket 2710 comprises side panels having at least two different, but similar configurations.
The basket 2710 has an open top, though the invention is not so limited, and when the sides are assembled, recesses 2751 can be formed to receive watering and feeding systems.
The basket 2710 is stackable with one or more other baskets to form a vertical, space-saving stack of apartments. Multiple stacks may be arranged within a frame, or arranged side-by-side to form a colony.
The basket as illustrated comprises twenty-five floor panels 2720 and fourteen side panels 2750, though one skilled in the art will recognize that any suitable number and arrangement of panels may be used to form a basket of any suitable size, shape and configuration.
In one embodiment, each floor panel can be between about approximately fifteen and about approximately twenty inches, and one implementation can be between about eighteen and about nineteen inches, by between about approximately twelve and about approximately fifteen inches, and in one implementation can be between about approximately thirteen and about approximately fourteen inches. The side panels have a height between about approximately eight and about approximately twelve inches, and one implementation can be about ten inches and a length between about approximately twenty inches and about approximately twenty five inches.
The basket 2710 as illustrated and described may hold about ten lbs per square foot. The number of birds each basket holds depends on the intended slaughter weight of the bird. In one implementation, the basket 2710 may hold about 90 six pound birds, about 140 four pound birds or about 209 2.2 pound birds.
The edges slope downwards to create a bowl channeling debris through the mesh openings 3023. As shown in
The center of the floor panel 2720 may be solid for injection molding purposes.
The floor panels 2720 include hinge elements 3032, 3033, 3034, 3035 extending below the mesh floor 3022 from each end of edges 3026 and 3027. A first pair of hinge elements 3032, 3033 extends down from edge 3026, and a second pair of hinge elements 3034, 3035 extends down from edge 3027. The second pair of hinge elements is offset from the first pair. As shown, hinge 3033 is positioned at a corner of the generally rectangular floor panel, whereas hinge 3032 is offset from the corner of the floor panel thereby allowing hinge 3034 of an interfacing abutting floor panel to be position adjacent hinge 3032 and aligned such that beam 3280 may be inserted through the hinge openings. Similarly, on the opposing side of the floor panel, hinge 3034 is positioned at the corner of the floor panel and hinge 3035 is positioned such that it is offset from the corner of the floor panel. Therefore, hinges 3033 and 3034 at diagonally opposing corners of the floor panel are positioned at the corner and hinges 3032 and 3035 are offset from the corner.
As shown in
As clearly illustrated in
As shown in
The side panels 2750 connect to the floor using the beams 3280.
The side panels 2750 are connected together to form the side walls of the basket 2710. In the illustrative embodiment, each side panel includes links along the first side and second side edges for connecting the side panel to an adjacent side panel. The links are configured such that the side panels may be connected at either 90° or 180°, as shown in
The illustrative basket comprises four different configurations of side panels, each with similar features, as described below.
The side panels 2750a further include hooks 3769 extending from the bottom edge for receiving edge beams 3280 that connect floor panels together.
The side panels 2750a further include a cavity, illustrated as recess 3781, formed in the top edge for allowing the passage of feeding tubes or pipes. As illustrated, these side panels 2750a can be positioned to extend along the short side wall of the basket adjacent the corner of the basket.
An inside ledge 3791 extends between the links 3762, 3772 above the beam openings 3552. The ledge 3791 slopes downwards and overlaps the floor panels 2720 when the basket is assembled to promote cleanliness. Even when the floor panels bow under the weight of animals in the basket, the overlap between the inside ledges 3791 and floor panel edges prevent separation between the components.
Above the ledge 3791, the space between the edges of the panels forms an expanding mesh 3793. The openings 3795 in the mesh 3793 grow larger the higher they are to accommodate growing poultry. In one implementation, the openings are between about approximately one and about approximately three inches wide, where in one implementation the openings are about approximately 2.2 inches and between about one and about approximately two inches tall, preferably about approximately 1.5 inches tall.
The side panel 2750a further includes openings 3797 below the ledge 3791 to promote airflow. The side panels used in the opposite corners from the side panels 2750a are substantially similar, except for the length of the inside ledge 3791.
The illustrative modular plastic basket provides a comfortable, sanitary, accessible environment with optimal air flow and ventilation for raising chickens or other products. The modular plastic baskets are easily assembled and stackable to save space.
Poultry can be raised in the basket from the beginning to the end of life. The basket may be easily removed from a poultry house and trucked to a process facility, where it is unloaded, cleaned, then sent back to a hatchery or poultry house.
The various poultry handling examples shown above illustrate a novel system and method for handling poultry. A user of the present invention may choose any of the above chicken handling embodiments, or an equivalent thereof, depending upon the desired application. In this regard, it is recognized that various forms of the subject chicken handling could be utilized without departing from the spirit and scope of the present invention.
As is evident from the foregoing description, certain aspects of the present invention are not limited by the particular details of the examples illustrated herein, and it is therefore contemplated that other modifications and applications, or equivalents thereof, will occur to those skilled in the art. It is accordingly intended that the claims shall cover all such modifications and applications that do not depart from the spirit and scope of the present invention.
Other aspects, objects and advantages of the present invention can be obtained from a study of the drawings, the disclosure and the appended claims.
