Instrument for monitoring the moisture content of wheat grain in the production process of drying

A method and instrument are considered for monitoring the moisture content of grain directly in a drying chamber. The method is based on the dependence of temperature and moisture content of drying agent and its gradient at the outlet from the drying chamber on grain moisture content. The instrument makes it possible to monitor grain moisture content in the range 13–20%. The main absolute measurement error for grain moisture content does not exceed 0.8%. The instrument is made on a practicable and inexpensive fundamental basis, and is reliable and simple in operation.
