Definitions
- the present invention relates generally to an apparatus for eradicating pests in commodities, wood products, paper products, machinery, appliances that dispense foods or drinks and packaging materials and, in particular, a portable apparatus for eradicating pests using heat.
- Wood packing such as pallets, dunnage, crating, packing blocks, drums, cases, load boards, pallet collars, commodities, related and un-related machinery and skids can be present in any imported, exported, or domestic consignment, including consignments which would not normally be the target of phytosanitary inspection.
- Wood packing is frequently made of non-manufactured, low quality inexpensive raw coniferous and/or non-coniferous wood that may not have undergone sufficient processing time or treatment to remove or kill pests present within raw wood and therefore becomes a pathway for the introduction and spread of pests.
- wood packing is very often re-used (in that packing received with an imported consignment may be used again to accompany a second consignment). Therefore, the true origin of any piece of wood packing material is difficult to determine and thus its phytosanitary status cannot be ascertained or guaranteed.
- Heat treatment is an effective method for controlling pests without the drawbacks of fumigation e.g., highly toxic chemicals, airtight fumigation containment, certified pest controller(s), regulation by various state and/or federal agencies, and lengthy treatment/clearing times. Studies have documented that temperatures at or above 120 degrees Fahrenheit for thirty minutes is lethal to insects and pests. (Forbes and Ebling 1987, Sheppard 1984, Quarles 1995, and Zeichner 1998)
- the NPPO National Plant Protection Organization
- the process for establishing import/export requirements for wood packing may be different from that used for commodities moving as consignments.
- Vending machines, water coolers, coffee machines and similar equipment lend themselves to be treated effectively with heat to eliminate pests without damaging the equipment. With the use of heat, no risk of chemical transfer to water or vending products can occur, thus greatly reducing liability. Moreover, there is a commercial need for a portable heat disinfestation apparatus that can eradicate pests and be moved from one location to another.
- the present invention describes a portable device that eradicates pests by the use of heat and that is relatively quick and easy to manufacture.

Abstract
A disinfestation apparatus that treats an existing structure with heat and is designed to be portable is disclosed.
Description
- The present application claims the benefit under any applicable U.S. statute to U.S. Provisional Patent Application No. 60/291,407 filed May 16, 2001, titled PORTABLE HEAT-TREATING DISINFESTATION APPARATUS.
- The present invention relates generally to an apparatus for eradicating pests in commodities, wood products, paper products, machinery, appliances that dispense foods or drinks and packaging materials and, in particular, a portable apparatus for eradicating pests using heat.
- Modern transportation means have made it feasible to transport foods, machinery and other commodities from one geographical region to markets in regions on the other side of the world. In addition, equipment that holds foods or drinks, such as vending machines, water-coolers, coffee machines, etc., have a high incident of infestation by cockroaches, other pests and larvae and their eggs. This infestation can be present in any imported, exported or domestic consignment due to the heat, moisture and dark cavities in their design.
- Wood packing such as pallets, dunnage, crating, packing blocks, drums, cases, load boards, pallet collars, commodities, related and un-related machinery and skids can be present in any imported, exported, or domestic consignment, including consignments which would not normally be the target of phytosanitary inspection. Wood packing is frequently made of non-manufactured, low quality inexpensive raw coniferous and/or non-coniferous wood that may not have undergone sufficient processing time or treatment to remove or kill pests present within raw wood and therefore becomes a pathway for the introduction and spread of pests. Furthermore, wood packing is very often re-used (in that packing received with an imported consignment may be used again to accompany a second consignment). Therefore, the true origin of any piece of wood packing material is difficult to determine and thus its phytosanitary status cannot be ascertained or guaranteed.
- In all regions of the world, imports of automobiles, machinery, parts and other non-food products are fumigated with Methyl Bromide or Ethylene Dibromide to kill pests hiding within various machinery or packaging. However, these chemicals can damage the ozone layer, and the residue left behind by these chemicals is harmful to people.
- Heat treatment is an effective method for controlling pests without the drawbacks of fumigation e.g., highly toxic chemicals, airtight fumigation containment, certified pest controller(s), regulation by various state and/or federal agencies, and lengthy treatment/clearing times. Studies have documented that temperatures at or above 120 degrees Fahrenheit for thirty minutes is lethal to insects and pests. (Forbes and Ebling 1987, Sheppard 1984, Quarles 1995, and Zeichner 1998)
- The NPPO (National Plant Protection Organization) has established requirements for non-manufactured wood packing to manage the pest risk associated with this pathway. The process for establishing import/export requirements for wood packing may be different from that used for commodities moving as consignments. The normal process of undertaking risk analysis to determine if measures are necessary and the strength of such measures are frequently not possible for wood packing material because its origin and phytosanitary status may not be known. For this reason, it has become mandatory to regulate wood packing broadly by applying globally accepted measures that eliminate any presence of the more important regulated pests and significantly reduce the risk for a number of others.
- Recent laws passed in Canada and in the European Union require that all wood and wood products and packing materials entering their respective countries be treated so as to eradicate pests. This invention embodies a proven treatment method which requires that wood packing be subjected to an elevated temperature (i.e., at least 56° Celsius) for an extended period of time (e.g., at least thirty minutes).
- Vending machines, water coolers, coffee machines and similar equipment lend themselves to be treated effectively with heat to eliminate pests without damaging the equipment. With the use of heat, no risk of chemical transfer to water or vending products can occur, thus greatly reducing liability. Moreover, there is a commercial need for a portable heat disinfestation apparatus that can eradicate pests and be moved from one location to another. The present invention describes a portable device that eradicates pests by the use of heat and that is relatively quick and easy to manufacture.

- For the purpose of this patent, the term “pest” shall be defined as, but not limited to, any unwanted living organism susceptible to eradication by means of heat (e.g., insects, biological organism, mold, fungus, anthrax, etc.)
- For the purpose of this patent, the term “heater” shall be defined as, but not limited to, any device that has the means to raise/increase the temperature of air or a given substance either directly or indirectly, through conduction, convection, or radiation. The source of heat can be derived from the means of a combustible fossil fuel (e.g., propane, natural gas, heating oil, etc.) electricity, steam, coal, or wood.
- For the purpose of this patent, the term “products” shall be defined as, but not limited to, non-manufactured wood packing (e.g., pallets, dunnage, crating, packing blocks, cases, load boards, skids, etc.), paper products, appliances that hold and dispense foods or drinks (e.g. vending machines, water coolers, coffee machines), and machinery equipment, and commodities.
- In describing a preferred embodiment of the invention, specific terminology will be selected for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and it is to be understood that each specific term includes all technical equivalents that operate in a similar manner to accomplish a similar purpose.
- Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings in which a portable disinfestation apparatus utilizing heat, in accordance with the present invention, is generally indicated at10.
- Referring to FIG. 1A, a
chamber 12 that is designed to be movable is set in place. Thechamber 12 is preferably insulated in order to conserve energy in bringing the interior of the chamber up to a desired temperature and in maintaining that temperature but may not be insulated in some cases due to use of existing truck body or the like. Thechamber 12 may either be of new construction or refurbished (e.g., a former reefer container, an insulated trailer on wheels, etc.). - The interior of the
chamber 12 may be designed to hold specific goods or commodities. For example, the width of thechamber 12 may accommodate a standard pallet, and/or shelves may depend from the walls to hold certain shipping containers. - In a preferred embodiment, the floor of the container may be reinforced to allow a forklift to ingress and egress. This feature will greatly facilitate loading and unloading of the
chamber 12. - The
chamber 12 preferably has a rectangular shape. This allows the chamber to be shipped conveniently on a flatbed truck, train car, ship or other means of transportation. - Referring to FIGS. 1A, 2,3, 4A and 5A, the
chamber 12 has a flat bottom 14, opposing parallel first and second endwalls 16 and 18 depending upward along the traverse side of the flat bottom 14, and opposing parallel third andfourth endwalls doors first endwall 16 to provide a means of ingress and egress to the interior of thechamber 12. - An important feature of the present invention is its portability. Forklift pockets may be formed below the
chamber 12 to allow a fork-lift to raise the chamber in order to move or reposition theapparatus 10. In an alternative embodiment, lifting mounts may be produced in the upper four comers of thechamber 12. The lifting mounts provide a means for an overhead crane, large fork-lift machine or ship's crane to attach to thechamber 12 in order to lift the chamber. - Other preferred embodiments are illustrated in FIGS. 1B, 5B,5C and 7. As shown in FIG. 5B, a plurality of
wheels 99 can be attached to the underside of saidchamber 12. (Alternatively, thechamber 12 can be attached to a flatbed trailer or other platform that haswheels 99.) Attached closer to the end of thechamber 12 opposite the wheels is astand 92 and ameans 97 for pulling thechamber 12. The stand allows theapparatus 10 to sit without external assistance. - As illustrated in FIGS. 1B, 5B, and5C the
chamber 12 may be adapted so that it can be easily mounted on, and removed from, atrailer bed 95. Thetrailer bed 95 has a plurality ofwheels 99 at its back end. At the front end of thetrailer bed 95 are ameans 97 to allow the trailer/chamber to be pulled by a truck (i.e., a tractor-trailer vehicle) and astand 92. - Referring to FIGS. 3 and 4A, the
rear wall 16 of the chamber has aninlet 28 and anoutlet 29. Aninlet duct 40, connects theinlet 28 to a direct firedheater 30. Theoutlet 29 is open to the ambient air. - In one embodiment a pair of
doors side walls doors chamber 12. - Referring now to FIGS. 6A and 6B, a typical direct fired
heating unit 30 is illustrated. This type of heating unit is usually identified by its elongatedcylindrical housing 32; however, some direct fired heaters have a rectangular or other polygonal shaped housing. A fan or blower connected to an electric motor and a burner assembly are mounted within thehousing 32. The fan or blower draws air in from theinlet end 34 of theheater 30, pushes the air through the housing and over the burner assembly and out the outlet end 36 of the housing. - In one embodiment the burner assembly is designed to mix oxygen from the air passing by with natural or propane gas. After an igniter ignites the air/gas mixture, the burner assembly ensures a controlled burn as long as gas is delivered to the burner assembly from an external source. Approximately the entire second half of the
housing 32 acts as a combustion chamber. As the air passes through the flame at the burner assembly and through the combustion chamber, it is heated to a desired temperature. - A
control box 38 is mounted on the exterior of thehousing 32. Thecontrol box 38 protects electronic circuitry used to control the operation of theheater 30. Specifically, the electronic circuitry controls the amount of gas delivered to the burner assembly, provides power to the electric fan motor and the starts the igniter. - As illustrated in FIG. 3, the
heater 30 is mounted on the outside of therear wall 16 of thechamber 12. Referring now to FIGS. 6A and 6B, first andsecond brackets heater 30 to the chamber'send wall 16. - Referring again to FIGS. 1A, 1B,3, 6A and 6B an
input air duct 40, connects theoutlet 36 of the direct firedheater 30 to aninlet 28 in the chamber. In FIG. 3, theoutlet 29 of thechamber 12 is located proximate theinlet 34 of theheater 30. This allows the heater to simultaneously draw in fresh air along with some of the relatively hot air being expelled from the interior of thechamber 12. This method saves energy while ensuring that the air inside of thechamber 12 stays at the desired temperature. - Referring now to FIG. 5C, a
portable apparatus 10 utilizes a remote indirect firedheater 32 as illustrated. Aninput air duct 40, connects the outlet of the indirect fired heater to theinlet 28 of thechamber 12. Theoutlet 29 of the chamber is connected to the inlet of the indirect firedheater 32 throughreturn air duct 41. This allows the heater to continuously re-circulate the heated air within the chamber thus saving energy and ensuring the air inside thechamber 12 stays at the desired temperature. - Referring now to FIGS. 5A, 5B and7, a
portable disinfestation apparatus 10 utilizing an indirect firedheater 50 is illustrated. The two types of disinfestation apparatus are basically the same except that the air in an indirect fired heat system does not come in direct contact with a burning flame. An indirect firedheater 50 is similar to gas-burning heaters found in many commercial buildings. - In one embodiment illustrated in FIGS. 7 and 14B the indirect fired
heater 50 has its output mounted directly over theplenum inlet 60 of thechamber 12.Ductwork 52 connects theoutlet 61 of thechamber 12 to the inlet of the indirect firedheater 50. (It should be noted that FIG. 4A shows theplenum inlet 28 as circular in shape; however, because the general shape and design of the indirect firedheater 50 is different than a direct firedheater 30, theplenum inlet 60 is usually rectangular when used with an indirect firedheater 50. - The interior of the chamber will now be described. Although the drawings show an indirect fired
heating system 50 in connection with the interior details, it would be understood by one skilled in the art that the interior chamber of anapparatus 10 using a direct firedsystem 30 is substantially identical. - A side cut away of the
chamber 12 is also illustrated in FIG. 7. Aplenum 55 is formed on the inside of theback wall 16. Theplenum 55 is substantially rectangular in shape and covers the entire width (i.e., fromlongitudinal wall 20 to longitudinal wall 22). A portion of the ceiling of the chamber forms the top of theplenum 55. Aplenum deck 56 forms the bottom. - Two diametrically
opposed ducts plenum 55 substantially the entire length of thechamber 12. Theducts duct - Referring now to FIG. 8, the face62 of the
plenum 55 is illustrated. FIG. 9A is a top view of the hypotenuse orlong side 64 of a triangular duct section. As illustrated, a plurality of mountingholes 66 is positioned along each edge of the hypotenuse side of the duct section. FIG. 9B is a side view of thehypotenuse side 64 of the duct section. - The bottom portions of the
hypotenuse side 64 are attached to the side wall (e.g., preferably with screws, but rivets, spot welding or other means may be used) of thechamber 12, while the top portion is attached in to the ceiling of thechamber 12. Thehypotenuse side 64 of the duct sections are joined to the upper left and upper right comers of the plenum face 62. Anend cap 71 seals off the end of each duct. - Duct end caps71, as shown in FIG. 10, close off the ends of each
duct hypotenuse side 64 and are secured by screws through mountingholes 69 to the ceiling and wall of thechamber 12. - The
ducts plenum 55 to be evenly distributed to the interior of thechamber 12. - In a preferred embodiment, the walls of the chamber are chamfered to form a plurality of parallel, vertically-oriented
channels 77 that extend from the ceiling to the floor of thechamber 12. Thechannels 77, best illustrated in the partial cross-sectional wall view of FIG. 11, help to ensure that the warm air does not stay suspended above the products placed inside the chamber. Thechannels 77 provide a vertical passageway for the air to circulate within thechamber 12. - FIG. 14A is an enlarged view of a floor portion. As illustrated, this system can utilize external rigid or flexible ducting as means of transport for heated supply air or return air, the floor is comprised of a plurality of T-shaped
supports 78 that extend upwards from abase 79. Referring again to FIG. 14A, the T-shapedsupports 78 define a plurality ofchannels 88 on the floor of the chamber. Thechannels 88 provide a horizontal floor-level passage for the air to move within thechamber 12. The T-shapedsupports 78 are made of metal in one embodiment so that they may support the weight of a fork lift or other machinery needed to load product within the chamber. - Referring now to FIGS. 13A and 13B, a
return baffle 70 depends from the deck of the plenum. Referring again to FIG. 7, thereturn baffle 70 ensures that only the cooler air near the floor of the chamber is returned to theheater 50. - In practice, the products are placed within the
chamber 12. Thedoors heater 50 ignites and the motor in the heater begins to turn the fan. Air is drawn out of thechamber 12 through theoutlet 61 and into theheater 50. The air is heated to a set temperature and is blown throughplenum inlet 60 into theplenum 55. Withinplenum 55, the heated air is divided substantially in two and directed into the ducts. - The
ducts chamber 12. Thegutters 77 direct the heated air downward along the walls ofchamber 12. Since hot air rises, some of the air directed by thegutters 77 moves to the center of thechamber 12. As the heated air cools, it falls to the floor of thechamber 12. The T-shapedsupports 78 providechannels 88 so that the cooled air can be returned, unobstructed to thereturn baffle 70 where it will eventually be drawn back through theoutlet 61 and into theheater 50. - Although this invention has been described and illustrated by reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made which clearly fall within the scope of this invention. The present invention is intended to be protected broadly within the spirit and scope of the appended claims.
