New Hydrothermal Equipment and Technology for Improvement of Black
The project will implement
a new combined drying-steaming technology on an industrial scale.
This new drying-steaming process is based on laboratory experiments.
During this planned process the drying and the steaming will be
carried out in the same vacuum drying chamber as a joint progress.
The drying will be followed by the steaming. The advantages of this
planned process are: the stress release process is unnecessary after
drying, no secondary drying process is needed after steaming, no
material transport is needed between drying and steaming.
A new combined drying-steaming
technology will be implemented on industrial scale. Steaming experiments
will be carried out on parquet dimension black locust wood samples
at laboratory conditions. The optimum steaming time will be determined
with different steaming temperatures. A drying-steaming equipment
will be designed and installed. Drying-steaming experiments will
be carried out in the new chamber with industrial size quantity
of wood. The steaming parameters created after laboratory experiments
will be modified with the data of industrial experiments. The colour
change caused by steaming will be monitored by computer-supported
colorimeter. The quality of drying and steaming will be qualify
regarding to the standards.
