FIELD OF THE INVENTION

The present invention relates to an apparatus and system for food storage.

BACKGROUND

Increasingly, food shortages loom in a world that grows enough food, but that sees harvests rot in fields, consumed by insects and rodents, or pilfered by thieves. In lesser developed countries, the source of these problems is often a lack of adequate food storage and security. Grain storage systems are also frequently antiquated and insufficient in a variety of ways, including relying upon old technology and old structures; these grain storage system deficiencies even exist in developed countries. Furthermore, many grain storage structures, such as silos, offer short term storage only and suffer from susceptibility to both internal and external hazards. The height of these type of structures also makes them vulnerable to severe weather as well as violent acts. As an additional deficiency, gas from the grain can build up internally in the storage structure leading to a potentially explosive, hazardous atmosphere.
These and other deficiencies exist.

SUMMARY OF THE INVENTION

An exemplary embodiment is a modular grain storage apparatus that is fixed. The storage apparatus comprises a scalable frame; a plurality of scalable side panels, each side panel securely attachable to other side panels, roofing panels, and the frame; and a plurality of scalable roofing panels that are securely attachable to other roofing panels, the side panels, and the frame.
Another exemplary embodiment is a modular grain storage apparatus that is mobile. The mobile storage apparatus comprises a scalable frame; plurality of hole-vented scalable floor panels, securely attachable to the frame; a plurality of wheels, securely attachable to the floor panels; a plurality of scalable side panels, each side panel securely attachable to the frame, one or more floor panels and securely attachable to one or more other side panels; and a plurality of roofing panels, each roofing panel securely attachable to one or more scalable side panels and the frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

It will be readily understood by those persons skilled in the art that the embodiments of the inventions described herein are capable of broad utility and application. Accordingly, while the invention is described herein in detail in relation to the exemplary embodiments, it is to be understood that this disclosure is illustrative and is made to provide an enabling disclosure of the exemplary embodiments. The disclosure is not intended to be construed to limit the embodiments of the invention or otherwise to exclude any other such embodiments, adaptations, variations, modifications and equivalent arrangements.
The following descriptions are provided of different configurations and features according to exemplary embodiments of the invention. These configurations and features may relate to providing an apparatus and system for storing grain and/or other foodstuffs. While certain nomenclature and types of applications or hardware are described, other names and application or hardware usage is possible and the nomenclature provided is done so by way of non-limiting examples only. Further, while particular embodiments are described, these particular embodiments are meant to be exemplary and non-limiting and it further should be appreciated that the features and functions of each embodiment may be combined in any combination as is within the capability of one of ordinary skill in the art.
The figures depict various functionality and features associated with exemplary embodiments. While a single illustrative block, sub-system, device, or component is shown, these illustrative blocks, sub-systems, devices, or components may be multiplied for various applications or different application environments. In addition, the blocks, sub-systems, devices, or components may be further combined into a consolidated unit. Further, while a particular structure or type of block, sub-system, device, or component is shown, this structure is meant to be exemplary and non-limiting, as other structure may be able to be substituted to perform the functions described.
Exemplary embodiments of the invention relate to grain storage structures or units which have a variety of features. The grain storage structures may have independent power sources and rely upon alternative energy sources. The structures may provide both long term and short term storage. The structures may be fixed or may be mobile. The structures may be constructed in a manner that places an economy on its material usage such that the structure is modular and cost effective to manufacture yet provides a high strength to weight ratio. The structures may incorporate a variety of security features. The structures are of a lower profile than existing structures providing less susceptibility to weather and other environmental hazards, including human hazards.
The structures may incorporate one or more sensors. The sensors may be both internal and external sensors. These sensors may be capable of monitoring a variety of conditions. By way of non-limiting example, the sensors may monitor temperature, humidity, weight of the contents, gases, access to the structure, power status, and location of the structure. The sensors may be configured such that a single sensor monitors a particular condition. Alternatively, a sensor may monitor a plurality of conditions. The sensors may be locally and/or remotely monitored.
The structures may incorporate a ventilation system preventing build-up of a moisture or harmful or dangerous gases. The ventilation system may be two-way to both ventilate the structure and be used to admit outside air into the structure to regulate the internal atmospheric conditions of the structure.
The structures may accommodate grain and/or foodstuffs in a variety of storage conditions. For example, the structure may accommodate bulk, bagged, crated, and box storage of grain. The structure may also accommodate canned or similarly contained foodstuffs. In one exemplary embodiment, the structure may be configured to USAID standards, capable of storing 1496 MT of one type of grain per module. The structure may have multiple such modules. The structures may be equipped with dual roll-up doors and access doors positioned on either side of the warehouse to enable first-in-first-out (FIFO) and last-in-first-out (LIFO) circulation of stored contents
The structures may further be reconfigurable to other configurations, including but not limited to, refrigerated storage, controlled atmosphere storage, and shelved storage for foodstuffs. Importantly, while exemplary embodiments are described herein with respect to storage of grain, the embodiments are not so limited and may be used for storage of a variety of foodstuffs, such as, for example, produce. Also other material, apart from foodstuffs, may be stored therein. It should be appreciated that appropriate modifications may be required to accommodate storage of other materials besides grain. Exemplary embodiments include two storage concepts: commercial warehousing that may be fixed, and mobile storage units that may be mobile.
The commercial warehousing facility may be the larger of the two embodiments. These units may be designed with the intent of providing short and long term centralized storage options for grain and other food stockpiles. The design is warehouse-like in appearance and modular in concept. The design is configured to be prefabricated and assembled with minimum effort. Aeration floor panels may be set on top of a formed concrete trench or on top of a flat concrete floor that may serve as the foundation.
Side panels are fasted to the foundation and to roof panels using internal pin locking hinges, allowing for security and customized scale. Each panel is produced with a number of standard and optional features according to end-user preferences, and then assembled on-site. Transparent panels may be placed around the tops of the side walls of the building to allow for sunlight, while reducing the chance of water leakage and improving roof load stability. The possible features of these panels and the available additional mechanisms are listed below. These are meant to be exemplary, non-limiting examples as it should be appreciated that other features are possible.
Exterior Panels:
Pre-fabricated, rust resistant steel panels
Reflective and insulating enamel/paint
Locking pin hinges placed on the interior side of panel (used to fasten panels together)
Built in foam or fiberglass insulation
Rubberized and sealed copings/thresholds (to prevent pest entry)
Green roof application built into roof panels (for insulation and renewable energy credits)
Rain capture feature built into roof panels, with water storage barrel hook up
Top load and side load door panels for entry into complex USAID compliant design
Internal Mechanisms:
Integrated bracket and racketing systems (to subdivide storage items)
Soft compartmentalization (dividers for a variety of grain to be stored in one location)
Passive inlets and exhaust vents
Mechanical ventilation fans
Hazardous gas monitors
Aeration fans (for grains)
Refrigeration cells (for perishables)
Controlled atmosphere cells (for perishables)
Electronic inventory monitoring
Distribution options for both bulk (fitted with collars/pumps and shaft) or bagged holds
Conveyor belt systems
Power Supply Options:
Petroleum fuel and gas generators
Photo-voltaic solar production integrated into roofing panels
On-site wind turbines
Grid power in-line hook up
Security:
Motion sensor door and perimeter exterior lighting
Security cameras
Electronic alarms
Barbed-wire roof copings
Razor-wire roof copings
Variety of locking options for all doors/openings (standard padlock, keypad, or hand scanner)
The mobile storage units, the smaller of the two exemplary embodiments, are designed with the intent of providing retail sized, transportable, closed containers for use on farms and smaller cooperatives for safe, secure grain and food storage. The mobile storage unit may borrow from technologies created for the commercial warehousing facilities, but given its application, is designed to be more economic (and therefore, less sophisticated) in nature. Rectangular in design, this unit may be pod-like in appearance. Like the commercial warehousing facility, the mobile storage unit may utilize the same rust resistant panel design and internal hinge locking devices to create a rectangular storage unit. The unit also may have a raised, hole vented floor. Reflective paint and insulation are also available. The unit can be accessed from either a side opening or top hatch, both of which have locking options. It may also include exhaust vents for passive moisture and warm air venting. The unit is mobile, but also can be placed on the ground and be pin secured. The unit has wheels that can lock in place in order to prevent theft. Trailer hitches may be attached to the unit, which also have lockable casings to prevent theft. The unit may have dimensions that allow for cargo-ship and train transportation, or have features that allow them to double as freight containers. Mobile storage units may be constructed so as to allow for direct use and integration into the commercial warehousing facilities.
FIG. 1A depicts a stationary modular storage apparatus 100 according to an exemplary embodiment of the invention. Storage apparatus 100 may comprise a scalable frame 101 a (shown in FIG. 2). The frame may comprise a plurality of beam-like elements. The beam-like elements may have a uniform length. The beam-like elements may have different lengths, depending on where they are located in the frame. The beam-like elements may have a cross-section that resembles an “I” shape. The beam-like elements may have a cross-section that resembles a “C” shape. Other cross-sectional shapes are contemplated, depending on the design preferences for the stationary modular storage apparatus.
The frame may be arranged to provide support for side panels 103 a and roofing panels 105 a. The frame may be constructed to a height sufficient to withstand inclement weather conditions. The frame may be made of steel. The plurality of beam-like elements may be joined using bolts, such as high-strength A325 type bolts. The frame may be securely attachable to a foundation. The foundation may be concrete, asphalt, or other earthen. The foundation may be trenched. The foundation may act as a barrier to burrowing vermin.

The roofing panels may be securely attachable to the frame 101 a using, for example, self-drilling screws. The roofing panels may be treated with an insulating material, such as fiberglass or foam. The roofing panels may be sloped (as shown in FIG. 1C). At least one of the roofing panels may include a rain capture feature. At least one of the roofing panels may be made of translucent material, as depicted by 105 b. The translucent material may act as a skylight to allow natural lighting of the interior of storage apparatus 100.
Storage apparatus 100 may be assembled using simple wrenches, drills and screw drivers. Storage apparatus 100 may be assembled without the need for welding. Floor panels, side panels, and roofing panels all may be easily loaded onto trucks and transported to the building site where the storage apparatus is assembled.
Storage apparatus 100 may include one or more racks 206, configured to store items, such as bags of grain. The racks 206 may be configured to accommodate bulk, bagged, crated, and/or box storage.
FIG. 1D depicts a modular stationary storage apparatus that has been adapted for increased storage using one or more scalable extenders 101 c that may be attached to frame 101 a at the base where the frame is connected to the ground or the foundation. The width and height of the modular storage apparatus depicted in FIG. 1D has been increased as compared to the modular storage apparatus depicted in FIGS. 1A-1C. Extender 101 c is shown in a cutaway view of the front of a modular storage apparatus. The scalable extenders 101 c may be of a sufficient length to allow frame elements 101 a to have a uniform length L1, as shown in FIG. 1D. Frame elements 101 a are shown on the outside of the modular storage apparatus in FIG. 1D, but they may be located behind side panels 103 a.
Extenders 101 c may be made of the same material as frame 101 a. Extenders 101 c may be made of steel. The extenders may be joined to the frame or other extenders using bolts, such as high-strength A325 type 1 bolts. The extenders may be securely attachable to the foundation using, for example, anchor bolts. While FIG. 1D depicts extender 101 c connecting frame 101 a to the foundation, extenders 101 c may additionally or alternatively be placed at other locations along the frame. For example, extender 101 c may be connected to frame element 101 a at the point where frame element 101 a adjoins one or more roofing panels. Extenders 101 c may also be securely attachable to side panels, roof panels, and floor panels, using, for example, self-drilling screws.
FIG. 1F depicts an exemplary embodiment of extender 101 c, from multiple perspectives. As depicted in FIG. 1F, extender 101 c may have a “c-channel” shape. “C-channel” extender 101 c is shown with two holes at each end to allow attachment to one or more frame elements 101 a. The cross-sectional shape of extender 101 c may be adapted to conform to the shape of the adjoining frame element 101 a, depending on the design needs.
FIG. 1G depicts another exemplary embodiment of extender 101 c. As shown in FIG. 1G, extender 101 c may have an “I” shape, or wide-flange design. In FIG. 1G, extender 101 c is shown with four holes at each end to allow attachment to one or more frame elements 101 a. The cross-sectional shape of extender 101 c may be adapted to conform to the shape of the adjoining frame element 101 a, depending on the design needs.
As used herein, the term “scalable” is defined to include the concept that the size of an element may be increased or decreased, depending on the design requirements for the modular storage apparatus. The scalable frame elements and/or panels may be manufactured to a certain size to meet design requirements of the modular storage apparatus. Alternatively, the scalable frame elements and/or panels may be configured such that the size may be altered during the assembly process of the modular storage apparatus. For example, the height, width, and/or length of a modular storage apparatus may be adjusted using one or more extenders. An extender may be attached to a frame element to increase the length of the frame element. This allows the frame elements to be scaled to provide a desired framework for different sized floor panels, roofing panels, and/or side panels. The scalable frame elements and/or panels may also be designed to be interchangeable.
Additionally or alternatively, as shown in FIG. 1E, at least a portion of the modular storage apparatus shown in FIG. 1D may rest on an elevated base 101 d. The elevated platform 101 d may be made of masonry or reinforced concrete.
As depicted in FIG. 2, the frame elements 101 a may be connected using one or more cable elements 101 b. Cable elements 101 b may act as a brace for frame 101 a.
Dimensionally, the exemplary stationary storage apparatus depicted in FIGS. 1A-1C and FIG. 2 may be 40 meters long, 15 meters wide, and 5 meters tall when fully assembled. When constructed, the combination of the frame 101 a and the roofing panels 105 a may have live load capacity of 600 N/m². The frame 101 a and roofing panels 105 a may have a snow load capacity of 200 N/m². The combination of the frame 101 a, side panels 103 a, and roofing panels 105 a may be able to resist a wind load of up to 150 km/hr. Because the roofing panels, floor panels, and side panels are modular and scalable, other dimensions are possible. A storage apparatus that is 40 m×15 m×5 m has a gross volume of 3,000 m³. Of this gross volume, approximately 1,536 m³may be usable for storage. For storing bagged grain, assuming one bag has a mass of 50 kg, and grain has a density of 713 kg/m³, the exemplary storage apparatus having the dimensions shown above could hold 21,903 bags of grain, as shown in the equation below:
Storage Capacity=1,536 m³×753 Kg/m³÷50 Kg/bag=21,903 Bags
For wheat, which has a density of roughly 790 kg/m³, the exemplary storage apparatus having the dimensions shown above could hold 24,269 bags of wheat, as shown in the equation below:
Storage Capacity=1,536 m³×790 Kg/m³÷50 Kg/bag=24,269 Bags
Storage apparatus having exemplary dimensions of 40 m×15 m×5 m may hold 1,800 MT of wheat.
The floor panels 102, side panels 103 a, and roofing panels 105 a may be made of a durable material. The material may be steel, such as 26 gauge steel that is hot rolled or cold formed. The steel may have a 350 MPa yield standard. The panels may be coated with a rust-resistant material. The floor panels, roofing panels, and side panels may be treated with a coating on either side to prevent deterioration. The floor panels, roofing panels, and side panels may be treated with a solar reflective substrate, such as paint or enamel. The floor panels, roofing panels, and side panels may be treated with flame-retardant materials.
The storage apparatus 100 having exemplary dimensions of 40 m×15 m×5 m uses significantly less steel than conventional storage structures. An assembled storage apparatus according to the present invention may be only 35% of the weight of a conventional structure. On a cost basis, the materials needed to construct the exemplary embodiment described above may cost 50% less than those used to build a conventional storage structure.
Stationary storage apparatus 100 may include one or more power generation devices or systems. The power generation devices or systems may include, without limitation, solar panels, wind turbines, and/or fuel-powered generators. The solar panels may be integrated with one or more of the roofing panels 105 a.

As will be understood by those skilled in the art, storage apparatus 300 may be compartmentalized to allow storage of both dry goods and perishable goods, as depicted in FIG. 3.
FIG. 7 depicts a stationary storage apparatus 700 adapted for controlled atmosphere storage. Controlled atmosphere storage refers to the monitoring and adjustment of oxygen (O₂) and carbon dioxide (CO₂) levels within a storage apparatus. As stored perishables respire due to metabolic activity, the levels of oxygen and carbon dioxide inside storage apparatus 700 will change. Controlled atmosphere storage may allow storage apparatus 700 to reduce the respiration rate of stored fruits and vegetables by 50% compared to refrigerated storage at the same temperature. Storage apparatus 700 may be adapted with one or more devices that may alter the levels of carbon dioxide and oxygen inside the storage apparatus.
Storage apparatus 700 may be adapted to include one or more scrubbers 710 to remove excess carbon dioxide. A scrubber may be, for example, a lime room adapted to absorb excess carbon dioxide. Storage apparatus 700 may be adapted to include ventilation units to add oxygen. Storage apparatus 700 may include one or more nitrogen displacement units to reduce oxygen levels inside storage apparatus 700. Storage apparatus 700 may include one or more nitrogen storage tanks and/or air compressors.
Storage apparatus 700 may include sealing materials 707 to create gas-tight storage. The joints between side panels, floor panels, and roof panels may be fitted with gas-tight tape or painted with flexible plastic paint. One or more side panels may be adapted to include a pressure/vacuum relief valve to maintain a desired pressure level inside the storage apparatus.
As shown in FIGS. 3 and 7, side panels 103 a may be treated with sealing material 307 or 707 to seal gaps between the side panels and the foundation. The sealing material may be, for example, caulk or foam strips. The sealing material may prevent essential gases from seeping out of the storage apparatus to aid in the preservation of perishable goods.
FIGS. 4-5 depict a stationary storage apparatus 400 that has been adapted for dry storage of grains, such as wheat, rice, corn, textile products and/or animal feed. Stationary storage apparatus 400 may include all the features of storage apparatus 100, as depicted in FIGS. 1A-1C and FIG. 2. Storage apparatus 400 may include one or more conveyer systems (not shown). A conveyer may be attached to frame 101 a. The conveyer may be configured to efficiently load and unload stored grain.
Stationary storage apparatus 400 may include one or more sensors 408 a. The sensors 408 a may be humidity sensors. Humidity sensors may be configured to detect atmospheric moisture within a storage unit. The sensors 408 a may be gas sensors. Gas sensors used in controlled atmosphere storages may be configured to detect the levels of gases within storage apparatus 400. Gas sensors 408 a may also be configured to monitor humidity levels.
Stationary storage apparatus 400 may include one or more temperature and or/moisture monitors 408 b. Temperature monitors may include one or more thermostats. Moisture levels and temperature affect grain deterioration. Temperature and gas monitors help detect grain temperature that may lead to mold growth, spoilage, sprouting, and insect infestation.
Stationary storage apparatus 400 may also include one or more ventilation systems. Ventilation systems may be configured to work in tandem with gas, humidity and temperature sensors to aerate the interior of storage apparatus 400 and prevent the buildup of harmful gases and/or moisture levels. Ventilation systems may be a combination of passive and mechanical venting devices. A passive ventilation device may include one or more louvres 409 a, or ridge vents. The ridge vents 409 a may be included in the side panels 103 a. A mechanical ventilation device may include one or more fans 409 b.
Temperature sensors 408 b, gas sensors 408 a, and ventilation systems may also be included in the refrigerated modular storage apparatus 300 and the controlled atmosphere modular storage apparatus 700.
Monitoring devices in modular storage apparatus 300, 400, and/or 700, such as gas sensors 408 a and temperature sensors 408 b, may be electronically connected to a network-enabled computer system for automated food storage monitoring and control (“the monitoring and control system”). The monitoring devices may gather monitoring data and relay the data to the monitoring and control system, which may be located on-site, or remotely connected to the monitoring devices via one or more networks.
The monitoring and control system may be configured to analyze the monitoring data to determine if one or more of the temperature levels, gas levels, and humidity levels have exceeded a threshold level. If a threshold level is exceeded, the monitoring and control system may display an alert to one or more users. The monitoring and control system may also be operably connected to the ventilation system to allow a user to activate one or more ventilation devices in response to the alert. The monitoring and control system may also be configured to automatically activate one or more ventilation devices to in response to an alert. Activating the ventilation system may involve expelling excess gases from the storage apparatus.
Monitoring devices in refrigerated storage apparatus 300 and controlled atmosphere storage apparatus 700 may be connected to the monitoring and control system described above. The system may be configured to activate controlled atmosphere storage devices in response to certain levels of oxygen and/or carbon dioxide that are detected by the monitoring devices. For example, if a threshold level of carbon dioxide is exceeded inside storage apparatus 700, the monitoring and control system may automatically activate one or more scrubbers to reduce the carbon dioxide levels inside storage apparatus 700 to an acceptable level that maximizes preservation of perishables, such as fruit and vegetables.
Grain storage apparatus 400, refrigerated storage apparatus 300, controlled atmosphere storage apparatus 700, and storage apparatus 100 may include one or more security devices, such as camera 407 a (shown in FIG. 4). Other security devices may include alarms and/or motions sensors. The one or more security devices may be connected to the network-enabled computer system. The security devices may alert the monitoring and control system when the storage apparatus has been breached or compromised. The alert may be an alarm. Security devices, such as surveillance cameras, may also be placed on the exterior of storage apparatus 400.
Other security devices may include one or more magnetic tags that may be attached to bags of grain or storage containers. The tags may be configured to trigger an alarm if they are improperly removed from the storage apparatus.
