A bin vent apparatus is described herein for use on a storage bin for agricultural products. The storage bin can have a sidewall and a roof defining an interior. The bin vent apparatus includes a plurality of discrete, roof-mounted vent filters. Each of the vents has an inlet for receiving air from an interior of the bin, an outlet for venting air from the vent, a fluid flow path between the inlet and the outlet, and one or more filters disposed in the fluid flow path between the inlet and the outlet to filter the air received from the interior of the bin. A fan is disposed in the flow path and downstream of the one or more filters, the fan being operable to cause air to flow into the inlet, through the filter, and out of the outlet.

A vent for a ventilated concrete floor structure, which includes parallel spaced-apart support beams and a concrete floor thereover, comprises upstanding longitudinally-extending sidewalls interconnected in transversely spaced-apart relation and a passageway therebetween for releasing air from at least one air duct underneath the floor to a ventilated space thereover. The passageway has an inlet at bottoms of the sidewalls communicated with an air duct and an outlet at tops of the sidewalls at an upper surface of the floor. The sidewalls are metallic. Upright sidewall portions extend in a height direction of the vent and upper sidewall portions defining the sidewall tops extend transversely outwardly from the upright portions to provide upper surfaces arranged substantially flush with the upper floor surface. The passageway is substantially prismatic, and the rectangular inlet opening is wider than the rectangular outlet opening. Lower sidewall portions are configured to rest on the support beams.

A grain handling system having an air system is presented that is capable of automatically detecting and clearing a plug in a tube of an air system using a central controller, an air pressure sensor, a dynamic pressure relief valve and a variable frequency drive connected to and controlling a blower motor. When a plug is detected, the central controller stops the flow of grain into the tube and ramps up the output of the blower motor to full capacity. Thereafter, the central controller performs an unplugging routine by opening and closing the dynamic pressure relief valve causing surges of air to impact the plug either breaking up the plug or bumping the plug along the tube until it clears. Once the plug clears, the central controller resumes normal operation.

A modeling framework for evaluating the impact of weather conditions on farming and harvest operations applies real-time, field-level weather data and forecasts of meteorological and climatological conditions together with user-provided and/or observed feedback of a present state of a harvest-related condition to agronomic models and to generate a plurality of harvest advisory outputs for precision agriculture. A harvest advisory model simulates and predicts the impacts of this weather information and user-provided and/or observed feedback in one or more physical, empirical, or artificial intelligence models of precision agriculture to analyze crops, plants, soils, and resulting agricultural commodities, and provides harvest advisory outputs to a diagnostic support tool for users to enhance farming and harvest decision-making, whether by providing pre-, post-, or in situ-harvest operations and crop analyses.

A system is presented for monitoring grain handling systems at a grain handling site. The system includes a central control system and one or more intermediate control devices communicatively connected to the grain handling systems. The central control system is configured to provide a first user interface configured to facilitate creation of a process flow and programming of the intermediate control devices to operate in accordance with the process flow. In one or more arrangements, the central control system is configured to control operation of grain handling systems to optimize the process flow for one or more performance parameters selected by a user.

Facilities for storing large quantities of potatoes, other tubers, vegetables, produce, and/or other crops are disclosed herein. In one embodiment, a facility configured in accordance with the present technology circulates air from a pile of potatoes into one or more ceiling cavities above the potatoes to warm ceiling panels. Aspects of this embodiment can reduce undesirable water formation on the potatoes.
