Application of high frequency vacuum wood dryer in mahogany furniture
For large section woods and hard hardwoods, especially valuable rosewoods, the technology used in high frequency vacuum wood dryers is more suitable. High frequency vacuum wood dryer heating is a medium heating that evaporates moisture by increasing the temperature, that is, the molecules in the wood rotate at a high speed, generate heat quickly, and then achieve rapid water absorption drying through vacuum negative pressure.
High frequency vacuum drying technology has the following advantages in the drying of valuable mahogany furniture:
1. Drying and stability: Because of the vacuum environment, the boiling point of water is low, and it can be vaporized at 60 °C. Low-temperature drying can greatly reduce the cracking, deformation and discoloration of wood. The high frequency vacuum wood dryer is especially suitable for temperature-sensitive valuable wood. .
2. Speed: There is no doubt that high frequency drying is fast. One is that the temperature gradient inside and outside the wood is high during the heating process, and the moisture is discharged quickly, and the other is that the vacuum negative pressure can quickly absorb moisture.
3. Good quality: There is a hydraulic platform on the top of the high frequency vacuum wood dryer, which can compress the wood, prevent deformation, and play the role of wood leveling.
