INCREASING THE ENERGY EFFICIENCY OF THE PROCESS OF OSCILLATING VACUUM-CONDUCTIVE DRYING OF WOOD BY MEANS OF A HEAT PUMP

The article presents the results of investigations of the energy-saving technology of oscillating vacuum-conductive drying of wood in which the heat of the moisture evaporated from the material in the stage of vacuum treatment is fed by a heat pump for raising the temperature of the material in the stage of heating. A method for calculating the rate of moisture removal from a heated wood in the process of vacuum treatment depending on the vacuum depth, temperature, moisture content, and of the material thickness has been developed.
