Vuosien varrella Valutecin yhteistyö kansainvälisesti johtavien tutkijoiden kanssa Ruotsissa ja Suomessa on johtanut useisiin uraauurtaviin innovaatioihin.
Pohjoismainen sahateknologia on kehityksen eturintamassa. Etuoikeus toimia kotimarkkinoilla, joilla on ehkä maailman vaativimmat asiakkaat, on antanut meille erinomaisen perustan myös kansainväliselle menestyksellemme.
Nykyään Valutecilla on käytössään useita tärkeitä patentteja, jotka kattavat kaiken edistyneistä ohjausjärjestelmistä älykkäisiin teknisiin ratkaisuihin ja kuivauksen periaatteisiin.
Patents
1972 Dynamical drying process.
1989 OTC process (Optimized two-stage continuous dryer).
1991 Adaptive control of a simulator controlled batch kiln (Using an integrated simulator into the control system).
1995 AdaptiveTDL-control (Real time generation of the drying schedule by listening to the water evaporation from the wood, using the temperature drop across the load).
1995 Heating with saturated steam (the “Relax method” with high power saturated steam).
1999 External air cooling of fan motors.
2000 Expert system integrated in the control system. (A tool that automatically helps the operator to optimize the drying process depending on the incoming material and desired end results. It can optimize capacity, quality and energy consumption, at the same time. In other words optimize the drying costs!)
2002 Method for high temperature or heat treatment of wood
2003 Method of heating of wood (Special control method to optimize the heating which works best with preheated pressurised water spraying systems).
2004 Support beams for a dryer. (To prevent “flat bend” of the bottom layers in the package).
2006 Pulling device for a continuous dryer (The “hook” that gives the benefit of having no chain, no motor or no sensor in the drying climate).
2008 A method for adapting the requirement of drying air in wood driers. (Comparing climate conditions with the TDL to determine the need of air velocity which minimizes electric consumption).
2008 Method for dynamic control of the drying period in a continuous dryer. (Measuring moisture content contactless and controlling the drying time on this feedback signal).
2009 Optical shrinkage measurement (To determine moisture content).
2011 Door machinery (Special solution for vertical doors).
2013 Drying arrangement for high energy recovery (Drying at two different temperature levels, using the same energy twice to recover more energy than traditional solutions)
2014 Partial use of the circulating air for heat recovery, using the energy twice.
2015 Bypass of circulation air (Bypassing part of the air pass the heat coil to achieve less total pressure drop which lowers electric energy consumption).
2017 Flexible TC- Progressive Dryer.
2018 TC-Progressive with Pre Heating.
2025 Closed Drying Loop Solutions (Patent pending) .
