subject: Automatic Control System For Wood Drying Kiln [print this page] System for wood drying kiln wherein the weight of a representative sample positioned remote from the batch of wood to be dried is monitored. The moisture content of the representative sample is calculated from the measured weight continuously and operational parameters with the kiln are automatically adjusted in response to the moisture content of the sample to provide desired drying conditions.
A monitoring system for a wood drying kiln having a housing with an interior wall surface, an area within the housing for placement of a charge of wood for drying of the charge of wood, and means for heating and humidifying the interior of the kiln, the monitoring system comprising: support means positioned adjacent the interior wall surface for supporting a representative sample of the charge of wood adjacent the interior wall surface and remote from the charge of wood; sensor means operatively connected to the support means for sensing a physical characteristic of the sample which is a function of moisture content in the sample; signal generation means operatively connected to the sensor means for generating a signal corresponding to moisture content of the sample as a function of the physical characteristic; control means operatively connected to the means for heating and humidifying the interior of the kiln and to the signal generation means for controlling the heat and humidity within the kiln in response to the signal received from the signal generation means;
. A monitoring system for a wood drying kiln having a housing with an interior wall surface, an area within the housing for placement of a charge of wood for drying of the charge of wood, and means for heating and humidifying the interior of the kiln during a drying process.
