subject: All Kind Of Wood Drying Equipment [print this page] A monitoring system for wood drying kilns 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, the monitoring system comprising:
support means positioned in the housing and adjacent the interior wall surface for supporting a representative sample of the charge of wood in the housing and adjacent the interior wall surface and remote from the charge of wood during the wood drying equipment process;
sensor means operatively connected to the support means for continuously sensing a physical characteristic of the sample which is a function of moisture content in the sample, during the drying process;
control system 30 in response, to adjust the appropriate control devices 60-63 and thereby regulate the drying system to achieve the desired wood dry equipments environment.
It is noted that several properly selected samples are needed and accurate control provided so that the wood drying kilns conditions satisfy both the needs of the fast- drying parts of the charge and the slow- drying parts. To avoid over- drying, the kiln conditions may have to slow the drying of the fast- drying lumber, so that the slow- drying lumber can "catch up", and ideally, all lumber in the stack reach the final desired moisture content at the same time. Also the invention is not limited to kilns for hardwoods. Pine or other softwoods, if used for furniture or other fine work may also be dried with the system of the invention.
