Apparatus and method for monitoring drying of an agricultural porous medium such as grain or seed

摘要

An apparatus and method for monitoring drying of an agricultural porous media such as grain and seed, includes deriving moisture content of the porous media using time domain reflectometry and utilizing moisture content to monitor and/or control the drying process. The porous media is positioned around a time domain reflectometry probe. An array of probes can be used to measure moisture in different areas of one batch of porous media or in a plurality of batches of porous media. The derivation of moisture content of the porous media around each probe would allow information to be provided to a dryer controller to alter the drying process if needed.
