14 Solutions at the cutting edge of technology. In every detail. Valmatics 4.0 is the only control system on the market that provides sawmills around the world with tools to automate and optimize drying in every type of lumber kiln. The system, which was developed for Industry 4.0, has a modern, intuitive user interface and is constantly being developed using the latest lumber drying technology. The high quality of the process is ensured by simulators programmed with data from hundreds of thousands of measurements to enable the calculation of drying processes with unbeatable accuracy from beginning to end. Valmatics 4.0 is also the only control system on the market to combine simulator technology with adaptive control, enabling the optimization of capacity, quality and energy consumption. Simultaneously. Stainless steel unit construction • All kilns are built using Valutec’s stainless steel construction system, an FEM calculated design in 2–10 mm steel. • Prefabricated modules with minimal welding. • Static joints with screw joints and silicone seals. • Resistant to heat expansion and fatigue. • No need for assembly welding. • Great protection against instability and fractures. Efficient motors Valutec’s continuous kilns are built with synchronous reluctance motors as an option. The motors have an efficiency standard of IE5, three levels above IE2, which is the current EU standard. This ensures energy efficiency and minimizes CO2 emissions. Energy savings can reach up to 25 percent, and because the bearings are permanently lubricated, they maintain a 10-20°C lower temperature, resulting in motors with service lives up to four times longer than motors with an IE2 rating. Doors • Robust doors made of aluminum or stainless steel. • Same elements and joints as the building system. • Mineral wool insulation and profiled. covers with good insulation against heat and noise. • The elements are held together by an outer frame with a sealing strip. • Bearing pins provide effective locking to the door frame’s sealing surface. • Door lift with electric vertical wire winch. Fans • Axial fans optimized based on operating conditions for maximum efficiency. • Adjustable or fixed blades. • For operating temperatures above 90 °C (195 °F), we supply motors with air cooling. • An external cooling fan provides cooling air for each motor. Baffles • F or sealing around the lumber load to prevent energy leakage and unnecessary moisture content variation. • Fixed side and roof baffles with EPDM rubber or polyamide wire cloth. • Adjustable side baffles with manual operation. • Roof baffles integrated with pressure frames. Lumber feed • Package feeder system with stable lumber trolleys and hooked bar feeder function with motor external to kiln. • Fully automatic feeder system at the input and output buffers. Pressure frames • For minimal deformation of top layers. • Stable, stainless steel guided load frames allows permanently mounted cylinders and fully tiltable frames with no risk of jamming. • Holds up to one metric ton per cylinder. • Stainless steel piston rods with Viton seals, stainless steel pipes and connections. • Also available in a scissors design for integration into existing kilns. Security solutions • Light beams at input and output of buffer and loading zone. • Safety switches at all wicket doors. • Hatch doors, operable from inside and outside.
