Interest Areas

A new device was invented for measuring the flow of seeds, grains, and other granular flow materials. The invention consists of a specially designed internal flow chamber section, a load cell arrangement, and a digital display unit. The electronic hardware assembly and software were developed to acquire, condition, and calibrate the signal from the load cell to flow rate. The device measures flow in real time and can be easily retrofitted in an existing seed or grain operation. Laboratory tests under static conditions showed that this device could precisely measure the flow rate in real time with an R2 of 0.9944, 0.9955, and 0.9880 for small-, large, and mixed-sized soybeans, respectively. Germination tests and the tests for mechanical damage showed that the device was gentle to seeds. Work is underway to adapt, build, and install the device in a seed facility and test its operation under real dynamic operating conditions, making the device more robust and thus more attractive for prospective licensees to commercialize the system and technology.
