A pallet 4 loaded with wood 3 is carried into a container 1, the container 1 is sealed, and a vacuum pump 7 is driven to reduce the pressure inside the container 1. At the beginning of this reduction operation, the pressure inside the pressure bag 17 is also reduced while being balanced with the pressure inside the container 1, and along with this pressure reduction, the pressure bag 17 expands and the gap between the container 1 and the wood 3 is reduced. It is filled with an expanded pressure bag 17. When the inside of the container 1 reaches the desired degree of vacuum, the vacuum pump 7 is stopped, and the drive motors 13 and 2 of the liquid pump 11 and the water pump 22 are turned off.
Start 4. At this time, since there is usually a certain pressure difference of 1 atm or less between the internal pressure of the pressure bag 17 and the internal pressure of the container 1, initially only the liquid pump 11 is driven and the processing liquid is pumped into the container 1. entered.
As the processing liquid is fed into the container 1, the internal pressure of the container 1 increases, and when it becomes equal to the internal pressure of the pressure bag 17, the water pump 22 is also driven, and the pressure bag 1
7, and when the pressure inside the pressure bag 17 becomes higher than the pressure inside the container 1 by more than the pressure difference set in the differential pressure switch 27, the water pump 22 stops. . By supplying water into the pressure bag 17 by turning the water pump 22 on and off, the internal pressure of the pressure bag 17 is maintained at a range equal to or slightly higher than the internal pressure of the container 1, and the inflated state of the pressure bag 17 is maintained. Ru. When the container 1 other than the part filled with the pressure bag 17 and the wood 3 is filled with the treatment liquid and the pressure reaches the pressure required for impregnation treatment, the pressure switch 16 is activated and the liquid pump 11 and water are filled. The pump 22 is stopped, and the wood 3 is impregnated with the treatment liquid. Due to the penetration of the treatment liquid into the wood 3, etc.
If the internal pressure inside the container 1 decreases, the pressure switch 16
The stop signal is released, the liquid pump 11 and possibly the water pump 22 are driven, and a predetermined pressure is maintained.
