METHOD FOR WOOD DRYING Russian patent published in 2001 - IPC

FIELD: wood drying in a drying chamber, in which the drying agent, for example air, circulates through a pile of wood placed in a drying chamber in the process of drying. SUBSTANCE: drying agent temperature drop (ΔT) is measured in connection with passage of the drying agent through the wood pile, and the obtained value of temperature drop is used for check-up or control of the state of the circulating drying chamber with due account made, for example, for the content of moisture in it and its temperature. Temperature T against the dry thermometer and temperature TV against the moist thermometer of the circulating drying agent are also measured near the wood pile, and the obtained information on temperature is additionally used for check-up or control of the state of the circulating drying agent with due account made, for example, for the content of moisture in it and its temperature. The drying process is carried out by means of a number of different stages (stages II-V) at variation of check-up or control of interrelated values of temperature drop (ΔT) against the dry thermometer, temperature T against the dry thermometer and temperature TV against the moist thermometer. EFFECT: optimized drying process by determination of time moment, when the necessary final moisture index is attained. 8 cl, 3 dwg
