In case of direct steaming the saturated water steam is directly inserted into the kiln.
In case of indirect steaming we heat the water which is at the bottom of the steam kiln facility and which evaporates into the space around it.
Direct steaming is faster than indirect but indirect steaming causes fewer mistakes on the wood. Steaming is a procedure which belongs to the heat treatment of wood.
During this procedure the following wood characteristics can be changed:
- The colour of the wood
- The wood becomes softer
- The wood can be bent in a better and easier way
- The wood gets sterilized
- With this procedure some of the mistakes in the wood can be covered
