The present invention is directed to agriculture systems, more particularly to a self-contained semi automated production facility capable of culturing plants and other organisms in a controlled environment. The present invention is in no way limited to the examples disclosed herein.
As population continues to grow, more land is required for habitation and more food is required for consumption. To accommodate growing urbanization and the decrease of arable land area, agricultural systems are centralizing to hotspots within the U.S. and other countries. However, these large-scale production systems may use inefficient methods, and some systems may select fruits and vegetables for their ability to be harvested early and transport for extended periods of time as opposed to being selected for good nutritional content. The increase use of transplants is needed to support the increase in farming for the rising population. Some consumers may wish to engage in supporting or growing locally produced foods for increased quality, nutrition and lower price. However, many cities lack the zoning laws to address small-scale agricultural operations. The present invention features a self-contained semi-automated production facility capable of culturing plants and other organisms in a controlled environment. The system of the present invention provides optimal environmental conditions, regardless of the external conditions, to allow for production of such plants and organisms. The system of the present invention helps to use better technologies to produce food, rather than the traditional methods. The present invention is in no way limited to the examples disclosed herein.
Any feature or combination of features described herein are included within the scope of the present invention provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this specification, and the knowledge of one of ordinary skill in the art.

The system 100 of the present invention comprises an outer shell 49. In some embodiments, the exterior shell 49 is similar to a shipping container, which is well known to one of ordinary skill in the art, however the exterior shell 49 is not limited to a shipping container. The exterior shell 49 may be constructed in a variety of sizes, for example sizes appropriate for small and large-scale use. An interior shell is disposed (e.g., slidably disposed) in the exterior shell 49. The system 100 may comprise one or more power sources. The power source, for example, may comprise an alternative energy-generating component to create an off-grid or grid-tied system such as one or more photovoltaic panels 55. One or more access points (e.g., doors 50) are disposed in the exterior shell 49. The shell 49 may further comprise a variety of other components, for example for providing strength and/or insulation (e.g., for helping to control the internal environmental conditions accurately). Insulating paint 48 may be coated on the exterior shell 49. In some embodiments, the system 100 further comprises a weather station 52, a GPS tracking and communications component 53, and/ora computer control system 54.
The system comprises user access points and alternative energy-generating components (e.g., Photovoltaic panels) The system may also feature communication components, which allow for communication of information to and from the device. The weather station communicates external environmental information to and from the device for control.
The system 100 may comprise an interior shell 47, which may slide into the exterior shell. The interior shell 47 may provide additional insulation for the system 100 (e.g., resistance to entry/exit or heating or cooling), a chemical resistant barrier, and beams for securing internal structural components (e.g., providing additional strength to the system 100), equipment, wiring, other devices, and the like. A chemical-resistant liner 46 may be disposed in the interior shell 47, allowing the unit to be effectively cleaned and sterilized in preparation for use or modification of the system without damaging the exterior shell 49. Various attachment or fitting components 44 may be disposed on the outside of the interior shell 47, allowing the interior shell 47 to be slid or mounted into the exterior shell 49.
The interior shell 47 provides a means of mounting growing modules and other materials needed for the system 100. For example, mounting components 45 may be disposed on the inner walls of the interior shell 47 for mounting growing modules, irrigation components, light components, and the like.
The present invention is not limited to a configuration with an exterior shell and an interior shell. For example, in some embodiments, the system 100 comprises a single shell, and in some embodiments, the system 100 comprises a plurality of shells.
The system 100 of the present invention comprises a plurality of growing modules, which are small isolated containment units. The system 100 creates micro-climates (e.g., with specific environmental parameters) inside the various growing modules installed in the system 100, and each growing module can be used to grow a specific plant or organism (or certain groups of plants or organisms), allowing the specific grown requirements of those plants or organisms to be met. The artificial micro-climates created allows for growth of these plants and organisms in non-traditional environments such as buildings and other urban settings. The growing modules allow for efficient control of parameters such as temperature, light, humidity, carbon dioxide concentration, and the like, because the growing modules have a small volume of space. The environmental parameters are also monitored via sensors 4 for feedback control.
The growing module may comprise a growing module container and a grid disposed inside the growing module container. The grid comprises a plurality of cells each adapted to hold a plant. In some embodiments, the grid is accessible via an opening access disposed in the growing module container. In some embodiments, the opening access is positioned in a top surface of the growing module container. In some embodiments, the opening access is positioned in a side surface of the growing module container.
In some embodiments, the growing module may comprise a lighting component and a cultivation component, and the housing that surrounds it, which holds the fans and part of the sliding mechanism. The removable and stackable modules are independently controlled and maintained in the system.
The system 100 may also be designed to provide the user information about the plant or organism as it progresses, either for educational purposes or to help the user to make decisions, e.g., to modify conditions or to harvest, etc.
The ability to instantaneously adjust environmental settings based on what is occurring inside the growing area and regulates the immediate conditions of the aerial cultivation environment surrounding the organism, e.g., using components 10, 27, and 30, allows for almost complete control of its culture and manipulation, modification, and/or response. Through the use of external weather stations (e.g., components 52 and 53), the system 100 may opt to utilize external conditions for heating and cooling the device, as well as using data for acclimatizing plants to external conditions where and when appropriate. Usage of passive cooling and heating will increase the efficiency of the device and lower its power requirements.
Using lighting sources in the growing module (e.g., component 200) such as, but not limited to solar collectors, LEDs, and fluorescent lights (e.g., components 6, 7, 8, 42), the culture and manipulation of plants and other organisms is made possible without use of sunlight. And, such light sources allow the system 100 to manipulate the light conditions as desired (e.g., alternative light cycles, etc.). Light diffusing panels [7] may be used to achieve uniform lighting throughout the growing module, while able to provide cooling and additional airflow (possibly directed) to the aerial portion of the growing environment. Additional heat generated by the light source may be separated by the diffusing panel and then ventilated away from the growing environment (e.g., via component 8). Removing excess heat reduces the load on the air conditioning units, creating a more efficient system.
Controlling the light output reaching the organism allows precise and accurate control of the plant's/organism's development through exposure to specific wavelengths of light emitted including but not limited to UV, PAR, and IR spectrum. Since the amount of light needed varies per plant/organism, the system 100 of the present invention integrates algorithms contained within the computer control systems 54. These algorithms and programs communicate with sensors 4 inside the growing modules to control light intensity, duration, color, quality, and other factors to yield the desired type of growth. This combination of automatic environmental control and sensing allows users to operate the device without prior knowledge of the plant's/organism's optimal conditions.
Computer control systems 54 coupled with sensors 4 (e.g., see components 30, 33, 37, 52, 53, 55, 57, etc.) monitor real-time parameters including but not limited to: air temperature (AT), solution temperature, RH (%), PAR (umol m-2 s-1), CO2, dissolved oxygen, and other parameters, in addition to visual monitoring through camera and other imaging techniques. Communications between sensors and the computer control systems 54 allow for automated control of the conditions required for growth of the selected organism based on pre-programmed set points so the user requires no prior experience or knowledge. Alternatively, a user may enter alternate parameters or set points. Integrating visual monitoring allows for pre-programmed decision software to completely control plant growth and reduces the user's interaction. The computer and other control systems allow remote monitoring, access, and control to be accomplished through terminals, computers, laptops, PDA's, and other communication devices. Remote access allows user interaction and troubleshooting to occur in a non-contact manner, helping to eliminate disturbing of the production process.
The system 100 of the present invention integrates hydroponic methods on a controlled recirculating system and allows for high-efficiency usage of inputs such as water and fertilizer. Some examples of hydroponic methods (e.g., “deep-flow hydroponics”) have demonstrated reductions in water usage, for example by over about 50 fold. Recirculating methods increase the efficiency of water use by re-using treated water and preventing it from running out of the system and into the ground. Using an internal irrigation system (e.g., see components 19, 23, 31, 33-40), water may be re-circulated continuously throughout the system. By treating with sterilizing lamps or anti-microbial lights and/or ozone-generating systems (e.g., see component 32), nutrient solution and water may be recirculated without introduction of pests, pathogens, and other organisms that may develop or be introduced otherwise. Other treatments (e.g., chemical additives) may be used with the system 100 of the present invention. The recirculation of nutrient solution and its sterilization using the system 100 may provide for optimal water usages and higher efficiency of usage for fertilizer as well.
The lighting and airflow fixture comprises a housing (e.g., a cylindrical housing) and a fan disposed in the housing and positioned to blow air downwardly (e.g., vertically). The lighting and airflow fixture as shown positioned the fan at the top portion of the housing and the bottom portion of the housing is open to allow air flow to exit the housing. A light emitting diode (LED) assembly board comprising LEDs is disposed below the fan in the housing, and a light diffuser is disposed below the LED assembly board. In some embodiments, the light diffuser comprises air flow orifices. An adjustable air flow nozzle extends downwardly from the fan and protrudes through the LED assembly board and the light diffuser. The adjustable air flow nozzle provides directed air flow downwardly (e.g., to the bottom portion of the housing). A plant (e.g., in a cell in a grid of a growing module) is positioned below the air flow. The LEDs provide light, and the light diffuser shapes and directs the light to the plant.
The lighting and airflow fixture may be a part of a growing module. As previously described, the growing module may comprise a growing module container and a grid disposed inside the growing module container. The grid comprises a plurality of cells each adapted to hold a plant. A light and airflow unit is positioned above the grid. A plurality of lighting and airflow fixtures are disposed in the light and airflow unit such that each lighting and airflow fixture is positioned above a cell and air flow from the fan and light from the LEDs of the lighting and airflow fixture is directed downwardly to its respective cell.
In some embodiments, the light and airflow unit disposed inside the growing module container above the grid comprises a light and a plurality of light diffusers positioned below the light such that each light diffuser is positioned above a cell. The light diffusers are adapted to shape light passed to the cells. In some embodiments, a fan is disposed above the light diffusers. Each light diffuser directs air flow downwardly to its respective cell.
