PROCEDURE FOR WOOD HEAT TREATMENT AND PLANT FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC B27K5/00 

FIELD: wood industry.

SUBSTANCE: perform the wood heating up to 160-260°C in the inert medium in the chamber, holding at high temperatures, removal of moisture from the wood, cooling, conditioning. The wood heating upto 160-260°C is carried out by the energy of the alternating electric field, created inside the wood at the pressure in chamber, exceeding the saturated water vapor, corresponding to the maximum heating temperature of the wood. The plant for the wood heat treatment contains a chamber, a heater, means for temperature, pressure monitoring and its adjustment, a loading trolley, and a tank for collecting condensate. The chamber is designed in the form of the autoclave press with operating pressure, exceeding the saturated steam pressure corresponding to temperature 260°C. Heater, which provides heating of wood up to 160-260°C, is made in the form of an electrical device that creates an alternating electric field inside the wood that is in the autoclave.

EFFECT: reduction of duration and power consumption of the wood heat treatment process.
