High frequency vacuum wood dryer is a kind of drying machine with low temperature in vacuum situation, smaller but much faster than the conventional kilns. It is suitable for all kinds of wood, from veneer/lamina/board to thick lumber, even heavy timber with large dimension.
For thin piece like veneer or floor board lamina, high frequency vacuum wood drying not only offer short drying cycle but also eliminate the problem of curve or shrink. For thick and hard wood, like Merbau,Mahogany,etc. HF wood dryer brings good drying quality with uniform moisture content, free of split or spark both on surface or inside of wood, short drying time will meet the customer’s demand for production.

1.High Frequency Vacuum Wood Drying Principle

High frequency electric field is as the main power for heating, it acts on the wood uniformly. The intensity of the heating depends directly on the moisture content of the wood an the electric field, while the moisture movement depends on the pemeability of the wood and internal pressure radient. In vacuum situation, the boiling point of water is decreased with decreasing pressure. The movement of water through wood increase leading to shorter drying time than can be achieved at atmospheric pressure.

2.Character of SAGA High Frequency Vacuum Wood Dryer

A.SAGA OFFER ONE BUTTON CONTROL TECHNOLOGY
Full automatic drying program within PLC control system for different type of wood, the worker don’t need to know too much knowledge about wood drying cook the wood perfect.
B.PRECISE AND RELIABLE MONITORING SYSTEM
High precision and stable monitoring spare will always guide on the machine both for warantee of good drying quality or safety of personal and machine.
C.WELL SELECT SPARE PARTS
We choose high grade stable spare parts which is tested for long time for the machine to make it stable running and problem free.
D.LOGICAL AND SAFE DESIGN
With more than 10 years of experienced engineer, the customer can expect a more logical and humanistic machine that very easy to use, stable running and help a lot in production.

4.WORKING PROCESS
(1) Load the wood on the feeding cart and place electrode after the layer finish.
(2) Push in to the tank and close the door.
(3) Start the system: vacuum pump starts first, when it reaches the set limit, HF power starts automatically to heat.
(4) When HF heat to the set max limit temperature, HF stop and wait, after temperature falls to the min limit, HF generator starts to heat again, during this cycle, vacuum pressure is always near -0.09Mpa, if it falls below set limit, vacuum pump starts automatically.
(5) When the drying cycle finish, the weight sensor will calculate and stop all the system, drying process finish.
