Conventional drying system

The conventional drying system only uses heat as an energy source. This way of drying is very interesting form an energy point of view when cheap energy sources such as wood or hot water are available. Air circulation, fans and heating elements are mounted between the roof and the suspended ceiling.

Our conventional drying chambers are very well insulated and vapour-tight. By introducing warm air into the room, the moisture contained in the wood is absorbed by the warm air and removed to the outside. This warm air circulates through the stacked wood. When the desired temperature an relative humidity is reached (this depends on the type of wood being dried), the ventilation system is modulated and opened by the control system. The modulating ventilation system ensures that part of this warm moist air is removed to the outside. This creates underpressure in the room. The negative pressure ensures that the same amount of fresh air is sucked in again from outside. By heating this fresh air, the relative humidity decreases and the wood again releases moisture to the air in the room.

This process repeats itself until the desired final humidity in the wood is reached.
