HF vacuum timber dryer

HF vacuum drying equipment is a relatively small and fast timber drying machine,it is used to dry hard wood and thicker timber ,which solves the distortion problems of hardwood and larger section timber ,it is very suitable for the solid wood furniture factory and timber process factory to dry the timber in last stage, because of its advantage of small batch production and short drying cycle .

1. Principle of HF vacuum dry

It adopts HF electric field as heating source, uniformly radiate to timber, and come through timber directly heat the moisture, which fast remove the moisture by vacuum water absorption function.

1.1 HF drying features and advantages:

1.Vacuum state: water boiling point is lower under the vacuum state, the moisture is heat to 60℃，it will start to vaporize in HF container ,so meeting the drying destination in low temperature sate ,then mostly reduce problems of timber distortion and crack, especially suitable for precious timber drying .

2. HF vacuum dryer has the sterilization and environmental protection functions

3.  Fast temperature rising:  No need hot conduction, outside and inside of timber will be heated at same time.

4. Fast dehydration: timber temperature will be a higher inside and lower outside during heating (it is opposite to the traditional heating method).

5. High quality : it is available to control timber moisture gap and surface humidity by controlling temperature rise speed and relative vacuum degree and cooling speed, so that it is efficiency to resolve the inside cracking ,end cracking ,and surface cracking ,color changed.  

6. Good Adaptability : it not only realizes drying in low temperature ,but also drying in high temperature, remove stress, solid resin, which most suitable for all of kinds species of the timber drying .

7. Lower drying cost

8 .No environment pollution

2.Vacuum degree:-0.07～0.09MPa, adjusting according to needs.

3.Dry Temperature: ≤90℃，you can set by user.

4.Dry Timber species: various of wooden timber

5. Initial moisture :< 40%

6. Finial moisture: user set it according to needs.

9. Temperature control: Temperature testing meter

10. Moisture checking:  adopts weight method and moisture testing meter.

 11. Safety protection:  Spark suppression and smog alarming.

 12. Avaliable Loading timber size: 1000mm(H)×1000mm(W)×3000mm(L)

 13. Control system: Manual delay
