Drying complex for quick drying of technical wood and obtaining firewood, which is widespread in developed countries.

Developing the drying complex, the company GreenPower took into account all the necessary parameters of the drying process of the wood. Wood drying involves a list of peculiarities, caused by the necessity of speeding up the process of moisture evacuation out of splitwood.

The main difference between wood drying and sawdust drying is a higher drying agent temperature necessary for the increase of the speed of moisture evaporation from wood surface.

A high coefficient of efficiency. We have reached this due to the completely new method of wood drying: direct contact of wood with heat carrier moving at a fast pace. Due to the fact that raw material is carried in trolleys, it is possible to use the working space of the chamber maximum efficiently.

The functions of the control of the heat carrier temperature at the outlet from the heat generator and at the inlet to the chamber allows prevention of «wood cementation», a common problem where temperature regime is incorrectly regulated.

Drying chambers of the company GreenPower are equipped with a heat pump and other systems of warmth recuperation and condensation. The main principle of drying lies in functioning of the systems of ingoing and outgoing air. The heated air is directed to the loaded trolleys and supplies heat, then it saturates with evolving from wood moisture and is displaced by incoming dry hot air.
