PANEL MANUFACTURING
The air is heated by hot air-water heat exchangers where the temperature of the water is around 100°C. The working temperature does not change the colour of the wood particles and has various benefits such as no risk of fire. A WESP is not required due to the low VOC emission levels that are well within the environmental limits. In addition, less resin is required in the production process because it is not lost through being burnt in the dryer. Another benefit of a belt dryer is the gentle handling of material. The material inside does not break up, thus retaining the size of the flakes at outfeed from the input. This further prevents the production of dust caused when flakes are broken. In the final section of the Dynadryer, where the drying process terminates and the moisture content of the wood is extremely low, the drying air is recovered and reintroduced into the initial section where the wet material is. This is called the Energy Recovery System as recycling the air through the system enables savings in terms of drying power. Across the systems and equipment devised by IMALPAL Group, words like “recovery”, “efficiency”, and “customisation” are recurring and deliberate choices highlighting IMALPAL Group’s response to the growing need to produce top quality panels from recycled wood waste. As the wood industry transits to new supply chains to mitigate its environmental impact, by focusing closely on ways to limit the waste of resources and power, it is possible to reduce emission levels to safeguard the environment the world live in.

The Dynadryer is a belt dryer which is equipped with a material dosing unit that forms a uniform mat of particles on the perforated belt. Belt dryers have many advantages and one specific benefit for wood recycling is that they run at low temperatures, with a maximum of 95°C.
