An installation for timber drying includes calorifer, fan, humidifier, temperature control sensors, controller. Additionally it includes sensors for measurement of wood resistance installed symmetrically in perimeter of the surface of timber and connected through amplifiers to inputs of differential amplifier output of which is connected through the module of absolute value of signal to the first input of comparator the second input is connected to the master of permissible signal difference, and the output – to the input of controller the outputs of which are connected to humidifier and calorifer. |
