Grain aeration systems and techniques
In one embodiment, the invention is directed toward a networked grain aeration control system. For example, the system can provide centralized monitoring of the aeration of a number of grain storage facilities, thereby improving the management of stored grain. The networked grain aeration control system can allow the custodian of the system to offer an aeration service. Farmers, or other individuals, cooperatives, or companies can purchase the aeration service at a cost proportionate to the amount of stored grain to be aerated and the duration of storage. In this manner, the purchaser of the aeration service can avoid relatively high fixed costs that can be associated with various aeration hardware.
1. A crop storage system for reducing defect levels to increase crop quality, comprising:
a crop storage facility;
a fan associated with the crop storage facility, wherein the fan is configured to aerate the crop; and
a computing device in communication with the crop storage facility, wherein the computing device is configured to:
manage the storage of the crop;
determine an amount of heat generated by the fan; and
adjust the management of the storage of the crop according to the determined amount of heat.
2. The system of claim 1 , wherein the computing device estimates the amount of heat generated by the fan, wherein factors associated with the estimate include the size of the crop storage facility and the size of the fan.
3. The system of claim 1 , further comprising a static pressure node, wherein the computing device is configured to receive static pressure data from the static pressure node and estimate the amount of heat generated by the fan from the static pressure data.
4. The system of claim 1 , further comprising a heat sensor for measuring the amount of heat generated by the fan, wherein the computing device is configured to receive the heat data and adjust the management according to the determined amount of heat.
5. The system of claim 1 , wherein the computing device is configured to manage crop temperature.
