Wood drying is the process with the largest energy consumption in the processing of wood products. In my country, wood drying accounts for 40%-70% of the total energy consumption. Therefore, the energy saving of the drying process becomes particularly important. The current drying methods (using moist air as the medium) include: atmospheric drying, conventional room drying, dehumidification drying, solar drying, vacuum drying, etc.

A wood vacuum dryer is a device that removes moisture from the interior of a container by drawing air from the container to achieve a predetermined vacuum. When dry, the canister is under vacuum. The jacket is heated with hot water (or steam or thermal oil). As the tank rotates at a low speed, the material continuously moves up and down, entering a "diamond-shaped trajectory" inside and outside the tank, and absorbs and evaporates.

There are many ways to dry wood, how many do you know? There are Solar drying, Vacuum drying, Flue gas drying and so on.
