| Outline of Final Research Achievements |
The microwave freeze dryer has been developed for waterlogged wood conservation. The equipment is a freeze dryer with the added capability of allowing microwave to applied in the drying chamber. The freeze dryer is capable of achieving an absolute pressure of 10Pa. The chamber size is φ900mm×1800mm. The microwave source is magnetron which has a frequency of 2.45±0.05GHz and a maximum output of 2kW.
Based on experiments of the microwave freeze drying, the microwave system generates heat within the waterlogged wood sample itself so that sublimation is accelerated. We found the potential of the microwave freeze drying to remove the water which remains in depth of waterlogged wood.
