METHOD OF DRYING WOOD AND PLANT FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC F26B5/04 F26B9/06 

FIELD: woodworking industry.

SUBSTANCE: method of drying wood is implemented as follows: first the wood heating is carried out in a drying chamber 1 at an atmospheric pressure, and in the receiver 5 a vacuum to 0.90 atm. is created with a vacuum pump 6, then the pump is turned off, the receiver is connected via valves 8 with a drying chamber, the time is noted during which the vacuum is equalised in them, then the vacuum pump is switched on, and the vacuum is brought in the drying chamber to 0.90 atm., then the drying chamber is disconnected with the receiver using the valves, the time is noted during which the vacuum in the chamber is reduced to 0.30 atm., and, during this time, it is brought to 0.90 atm. with the vacuum pump in the receiver again, and the receiver is connected again to the drying chamber, the time is noted during which the vacuum is equalised in the chamber and in the receiver, the vacuum pump is switched on and the vacuum is brought in the drying chamber to 0.90 atm., the receiver is disconnected with the drying chamber and repeat the previous steps until the industrial wood achieves the given relative humidity. And each chamber 1 of the plant for drying is made of two horizontally adjacent sections - drying 3 and heat-ventilating 4 that have a common leakproof welded closed housing in the form of two cylindrical surfaces, interconnected by a generator, the inner girders of the chamber 1 are located inside the housing 1, made of profile pipes, and in the heat-ventilating compartment 4 the heat panel and the vent panel parallel to it are mounted along the entire length of the housing that are covered with metal sheets to form with the compartment housing the space which is open from one side to the lateral surface of the industrial wood, and from the other - to the input of stream of vapour-air mixture from the drying compartment to the fans.

EFFECT: reduced costs.
