Description:
Drying chambers for drying lumber are equipped with high-quality equipment. The drying quality is achieved through electronic control and process control.

Our products have proven themselves to be the best when drying various species, both coniferous and hardwood. UVN- are used not only for drying lumber, but also for heating industrial premises. At the same time, woodworking waste is used as fuel, using these heating units, you get a very cheap solution for heating industrial premises.

The SKD-60 drying complex based on wood waste with a UVN-250 heat generator.

The drying complex is designed for drying lumber with a one-time loading of a 68-69 cubic meter drying chamber with automatic control, autonomous heat supply from the UVN heating unit.

The principle of operation of the UHF:
hot gases from the furnace furnace pass through the flue channels of the heat exchanger, give off heat to the heated air, after which they go into the chimney. And the heated air flows from the heat exchanger into the drying chamber, where, passing through the stack, it heats the lumber and takes away moisture. The moist and cooled air is fed back into the heat exchanger, dehumidified and reheated, and forcibly enters the chamber by purging with a centrifugal fan. For forced dehumidification of the air on the heating unit, there are dampers for the inflow of fresh air and the discharge of wet air. The temperature in the chamber is regulated by the actuating mechanisms of automation (blower fan, relief valve and air supply, etc.)

The heat carrier is heated air, which is supplied to the drying chamber from the heating unit by a fan.

The drying chamber is a modular prefabricated steel structure.

The frame consists of profile elements.

Sandwich panels made of aluminum, sheet thickness 0.8, with mineral wool insulation with a density of 110 kg/m3, of own production, with an outer wall made of profile metal, were used as wall and roofing elements.

The modular design allows additional modules to be connected, which expands the capabilities of the complex and significantly reduces the cost of the upgraded complex. The gate of the chamber is hermetically sealed, sliding on a rail using an opening mechanism.

There is a door between the chamber and the furnace compartment, where the UVN heating unit is located, for servicing the chamber during the drying cycle.

Thermally protected axial reversible fans are installed in the SCD chamber, which ensure the optimal required speed of air movement through stacks of lumber.

The ventilation system for the supply and distribution of coolant consists of: a discharge fan, axial reversible fans mounted on a frame under a raised ceiling, a system of supply and exhaust ducts.

The fuel for the heat unit is woodworking waste (sawdust, bark, shears, dead wood, firewood), peat, etc. Pre-grinding, sorting, and other fuel preparation is not required. The fuel can be supplied to the furnace in mixed form, even with a high degree of humidity (up to 65%) without pre-drying. The installation is easy to maintain and reliable in operation, allows you to recycle waste and reduce the cost of drying lumber. The download is manual.

The automatic wood drying control system is made up of controller modules. The system includes 8 moisture sensors of lumber, 2 temperature sensors, 2 equilibrium humidity sensors. The software of the system allows drying of various types and grades of wood (spruce, pine, oak, birch, larch). The control and operation of the equipment is carried out by the Litouch automation system. Active control of the final moisture content of lumber is up to 7%, and control is carried out according to the average humidity value.

Along with active monitoring and programmatic regulation of the drying process, the automatic control system monitors the condition of the equipment and ensures trouble-free operation of the installation. The system has three operating modes: automatic, semi-automatic, and manual.

The drying complex is supplied in the form of separate blocks and nodes, and is assembled on a pre-prepared foundation. The foundation is made by the Customer according to the drawings of the Supplier.
