Specialists from the Yuri Gagarin State Technical University of Saratov (SSTU) have developed a highly efficient wood drying technology — the method speeds up the process and makes it more gentle.
The method of obtaining wood fuel developed by SSTU scientists is unique and includes several important stages.
The technology is based on the sublimation process: wood waste is wetted, then frozen and placed in a sublimation chamber. When heated to 40-50 degrees, water transitions from a solid state (ice) to a gaseous state. The weight of the material is reduced up to 10 times, and the structure of the raw material and its properties are preserved.
The technology will be used in the processing of sawdust generated during logging, woodworking, and the activities of communal services. The final product can be used to improve soil and develop new building materials.
