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.

Embodiments of systems and approaches for managing post-harvest crop quality and pests are described. Such a system may include a plurality of edge devices each comprising sensor components and collectively forming a mesh network, for measuring the local physical environment within stored crops and, for example, transmitting the measurements to a service from within the crop storage area. In certain embodiments, such a system may be used to manage post-harvest crops and storage areasfor example, approaches are described for determining fumigation treatment duration, determining phosphine dosage, determining heat treatment duration, and determining safe storage time for crops.

A tower used to extend the life of the grains in the period of their storage, through procedures of grain humidification, sterilization, cooling, freezing and drying, which can be applied together or separately according to with the need of each particular cultivation, offering a multifunctional tower of high performance and low fuel & energy consumption, low noise and eco-friendly, not contaminating the grains that make the heat exchange with steam.

An apparatus for connecting a heater to a grain bin aeration fan features a multi-piece adapter device having a connection adapter with inlets for receiving flexible ducts from a heater. The connection adapter can be used on its own to directly interface with a grain bin aeration fan of a first size, or can be used in combination with a cooperative sizing adapter to adjust an effective outlet size of the adapter to better fit a grain bin aeration fan of a different second size. An ambient air intake in the connection adapter entrains ambient air into the heated air stream.

A method for silaging harvested crops includes distributing and compacting silage consisting of shredded foliage plants in a silo. The silo is then sealed and then fermented in the silo. At least one part of the silage is flushed with an inert gas after an aerobic phase of the fermentation is detected with a first sensor. The inert gas may also be introduced into the silage if a penetration of atmospheric oxygen is detected in the silage with a second sensor.
